 従来から血液を採取するためのさまざまな穿刺器具や、それとともに用いられる使い捨て式のランセットが開発されている。このような穿刺器具においては、ランセットを穿刺器具に取り付けたり取り外したりする際に、ランセットの一端から露出した穿刺針に誤って手などに刺してしまう危険性があった。上述の問題を受け、穿刺針を囲むキャップを有し、穿刺針に直接触れる危険性がなく穿刺器具に対してランセットの着脱が可能な穿刺針カートリッジや再装着しても再利用を防止することができる穿刺針カートリッジが開発されてきた(例えば、特許文献1参照)。 Conventionally, various puncture devices for collecting blood and disposable lancets used therewith have been developed. In such a puncture device, when attaching or removing the lancet to / from the puncture device, there is a risk that the puncture needle exposed from one end of the lancet may be mistakenly inserted into a hand or the like. In response to the above-mentioned problems, a puncture needle cartridge that has a cap that surrounds the puncture needle and has no risk of direct contact with the puncture needle and allows the lancet to be attached to and detached from the puncture device, and prevents reuse even if it is remounted. A puncture needle cartridge that can be used has been developed (see, for example, Patent Document 1).

 以上のように構成される穿刺針カートリッジ105と穿刺装置本体101の再使用防止及び露出防止の動作について説明する。 The operation of preventing reuse and preventing exposure of the puncture needle cartridge 105 and the puncture apparatus main body 101 configured as described above will be described.
 まず、穿刺針カートリッジ105と穿刺装置本体101の各動作状態について説明する。 First, each operation state of the puncture needle cartridge 105 and the puncture apparatus main body 101 will be described.
 図5乃至図10は、穿刺針カートリッジ105と穿刺装置本体101の各動作状態における要部断面図である。図5は、穿刺針カートリッジ105装着前を、図6は、穿刺針カートリッジ105を穿刺装置本体101に装着した状態を、図7は、保護キャップ202を分離した状態を、図8は、穿刺後の状態を、図9は、廃棄後の状態を、図10は、廃棄後、再装着した状態を、それぞれ示す。 5 to 10 are cross-sectional views of the main part of the puncture needle cartridge 105 and the puncture apparatus main body 101 in each operation state. 5 shows a state before the puncture needle cartridge 105 is attached, FIG. 6 shows a state in which the puncture needle cartridge 105 is attached to the puncture device main body 101, FIG. 7 shows a state in which the protective cap 202 is separated, and FIG. FIG. 9 shows a state after disposal, and FIG. 10 shows a state after disposal after re-installation.
 [穿刺針カートリッジ105装着前(図5)]
 図5は、第1アーム209の先端部が穿刺針ホルダ201(図3参照)の開口部211から露出して、ランセット本体203の前方への移動を規制する<第1の状態>を示している。
[Before puncture needle cartridge 105 is mounted (FIG. 5)]
FIG. 5 shows a <first state> in which the distal end portion of the first arm 209 is exposed from the opening 211 of the puncture needle holder 201 (see FIG. 3), and the forward movement of the lancet body 203 is restricted. Yes.
 [穿刺針カートリッジ105装着時(図6)]
 穿刺針カートリッジ105が穿刺装置本体101に装着されると、穿刺針カートリッジ105を構成するランセット本体203のチャッキング部206がプランジャ103に把持される。穿刺針カートリッジ105の装着と同時に、穿刺装置本体101は、穿刺針カートリッジ105の装着に伴うプランジャ103に設けられた穿刺バネ(図示せず)の付勢により、穿刺のためのチャージ動作が行われて、穿刺の準備状態となる。
[When puncture needle cartridge 105 is mounted (FIG. 6)]
When the puncture needle cartridge 105 is mounted on the puncture device main body 101, the chuck 103 of the lancet main body 203 constituting the puncture needle cartridge 105 is gripped by the plunger 103. At the same time when the puncture needle cartridge 105 is mounted, the puncture device main body 101 is charged for puncture by the bias of a puncture spring (not shown) provided on the plunger 103 when the puncture needle cartridge 105 is mounted. Thus, preparation for puncture is made.
 [保護キャップ202取外し時(図7)](保護キャップ202なし状態)
 図7は、穿刺針カートリッジ105装着時(図6)において、ランセット本体203と保護キャップ202が分離された状態を示している。
[When removing protective cap 202 (FIG. 7)] (Without protective cap 202)
FIG. 7 shows a state where the lancet body 203 and the protective cap 202 are separated when the puncture needle cartridge 105 is attached (FIG. 6).
 [穿刺後(図8)](保護キャップ202なし状態)
 穿刺装置本体101に備えられている穿刺ボタン108の押下により、ランセット本体203が前方へ移動し、穿刺針207の先端が穿刺針ホルダ201から突出することで皮膚を穿刺する。図8は、その穿刺後に穿刺針207が戻った状態を示している。このとき、第1アーム209の先端部及び第2アーム210の先端部は穿刺針ホルダ201の内側に存在する。
[After puncturing (FIG. 8)] (without protective cap 202)
When the puncture button 108 provided on the puncture apparatus main body 101 is pressed, the lancet main body 203 moves forward, and the tip of the puncture needle 207 projects from the puncture needle holder 201 to puncture the skin. FIG. 8 shows a state where the puncture needle 207 has returned after the puncture. At this time, the distal end portion of the first arm 209 and the distal end portion of the second arm 210 are present inside the puncture needle holder 201.
 上述のように、第1アーム209の先端部と第2アーム210の先端部とが穿刺針ホルダ201内に納まって、ランセット本体203が穿刺針207の軸方向に移動可能な穿刺後の状態が<第2の状態>である。 As described above, the distal end portion of the first arm 209 and the distal end portion of the second arm 210 are accommodated in the puncture needle holder 201 so that the lancet main body 203 can move in the axial direction of the puncture needle 207. <Second state>.
 [廃棄後(図9)](保護キャップ202なし状態)
 図9A.Bに示すように、穿刺装置本体101から使用後の穿刺針カートリッジ105を抜き、使用後の穿刺針カートリッジ105を廃棄する。図9Bは、第1アーム209の先端部及び第2アーム210の先端部がそれぞれ、穿刺針ホルダ201の開口部211(図3参照)から露出して、ランセット本体203の前方への移動を規制する<第3の状態>を示している。廃棄された穿刺針カートリッジ105は、ユーザの誤操作によって、ランセット本体203の後端部(チャッキング部206側)が前方に押された場合に、まず、第2アーム210の先端部が穿刺針ホルダ201に係合し、穿刺針207の露出を防止する。さらに、第2アーム210が破損した場合にでも、第1アーム209の先端部が穿刺針ホルダ201と係合し露出を防止する。このように廃棄後には、常に2種類のアームが針の露出防止にはたらくことにより、より安全な製品とすることができる。
[After disposal (Fig. 9)] (Without protective cap 202)
FIG. 9A. As shown in B, the used puncture needle cartridge 105 is removed from the puncture apparatus main body 101, and the used puncture needle cartridge 105 is discarded. FIG. 9B shows that the distal end portion of the first arm 209 and the distal end portion of the second arm 210 are exposed from the opening 211 (see FIG. 3) of the puncture needle holder 201, and the forward movement of the lancet body 203 is restricted. <Third state> is shown. When the rear end portion (the chucking portion 206 side) of the lancet body 203 is pushed forward by a user's erroneous operation, the discarded puncture needle cartridge 105 first has the tip end portion of the second arm 210 as the puncture needle holder. Engage with 201 to prevent exposure of puncture needle 207. Furthermore, even when the second arm 210 is damaged, the tip of the first arm 209 is engaged with the puncture needle holder 201 to prevent exposure. Thus, after disposal, the two types of arms always work to prevent the exposure of the needle, so that a safer product can be obtained.
 [廃棄後再装着(図10)]
 図10は、廃棄後にリキャップ(保護キャップ202の再装着)された穿刺針カートリッジ105を穿刺装置本体101に再装着した状態を示している。廃棄後の穿刺針カートリッジ105の穿刺装置本体101への再装着それ自体は可能であるものの、第2アーム210の先端部が穿刺針ホルダ201から露出し、第2アーム210の先端部と穿刺針ホルダ201が係合することによって、ランセット本体203が前方へ移動して穿刺を行うことを防止する。つまり、廃棄(使用)済みの穿刺針カートリッジ105は、間違って再使用することはできないため、安全である。
[Re-install after disposal (Fig. 10)]
FIG. 10 shows a state in which the puncture needle cartridge 105 that has been recapped after disposal (reattachment of the protective cap 202) is reattached to the puncture apparatus body 101. FIG. Although it is possible to reattach the puncture needle cartridge 105 to the puncture device main body 101 after disposal, the tip of the second arm 210 is exposed from the puncture needle holder 201, and the tip of the second arm 210 and the puncture needle Engagement of the holder 201 prevents the lancet body 203 from moving forward and puncturing. That is, since the discarded (used) puncture needle cartridge 105 cannot be reused by mistake, it is safe.
 上述したように、穿刺針カートリッジ105は、第1アーム209の先端部が穿刺針ホルダ201から露出して、ランセット本体203の前方への移動を規制する<第1の状態>と(図5参照)、第1アーム209の先端部と第2アーム210の先端部とが穿刺針ホルダ201内に納まって、ランセット本体203が穿刺針ホルダ201内を移動可能な<第2の状態>と(図8参照)、第1アーム209の先端部と第2アーム210の先端部が、それぞれ穿刺針ホルダ201から露出して、ランセット本体203の前方への移動を規制する<第3の状態>と(図9B参照)を取り得る。 As described above, in the puncture needle cartridge 105, the distal end portion of the first arm 209 is exposed from the puncture needle holder 201, and the forward movement of the lancet body 203 is restricted (first state) (see FIG. 5). ), The distal end portion of the first arm 209 and the distal end portion of the second arm 210 are accommodated in the puncture needle holder 201, and the lancet body 203 is movable in the puncture needle holder 201 (second state) (FIG. 8), the distal end portion of the first arm 209 and the distal end portion of the second arm 210 are respectively exposed from the puncture needle holder 201 to restrict the forward movement of the lancet body 203 <third state> ( (See FIG. 9B).
 第2アーム210の先端部が穿刺針ホルダ201から露出することによって、使用後の穿刺針カートリッジ105を穿刺装置本体101にセットし、穿刺動作をさせようとしても、第2アーム210の先端部が穿刺針ホルダ201に係合し、(図10参照)、ランセット本体203の前方への移動を規制する。また、第2アーム210は、第1アーム209以上の強度を持っているため、ユーザの強引な操作を防止することができる。 When the distal end portion of the second arm 210 is exposed from the puncture needle holder 201 and the puncture needle cartridge 105 after use is set in the puncture device main body 101 to perform the puncture operation, the distal end portion of the second arm 210 is not moved. It engages with puncture needle holder 201 (see FIG. 10) and restricts the forward movement of lancet body 203. Moreover, since the 2nd arm 210 has the intensity | strength more than the 1st arm 209, a user's forcible operation can be prevented.
 このように、使用済み穿刺針カートリッジ105の再使用及び穿刺針207の穿刺針ホルダ201からの露出を確実に防止することができる。 As described above, the reuse of the used puncture needle cartridge 105 and the exposure of the puncture needle 207 from the puncture needle holder 201 can be reliably prevented.
 次に、第1アーム209と第2アーム210の動作についてさらに詳細に説明する。 Next, the operations of the first arm 209 and the second arm 210 will be described in more detail.
 上記<第1の状態>、<第2の状態>、<第3の状態>及び「廃棄後の穿刺針207の露出防止状態」にある時の第1アーム209及び第2アーム210の動作について述べる。 Regarding the operations of the first arm 209 and the second arm 210 in the above <first state>, <second state>, <third state>, and the “prevented exposure state of the puncture needle 207 after disposal” State.
 〔第1の状態〕
 <第1の状態>は、穿刺針カートリッジ105を穿刺装置本体101(図1参照)に装着前の状態である。
[First state]
<First state> is a state before the puncture needle cartridge 105 is attached to the puncture apparatus main body 101 (see FIG. 1).
 第1アーム209は、ランセット本体203が前方へ移動するのを防止する。第1アーム209の先端部は、穿刺針ホルダ201から、その先端部が露出する。第1アーム209の先端部は、ランセット本体203が前方に移動しようとした時に、穿刺針ホルダ201の開口端部214(図5参照)部分に係合し、前方への移動を規制する。この構成により、特に通常手順と異なり、穿刺針カートリッジ105を穿刺装置本体101に装着する前に、保護キャップ202が外されてしまった場合でも、穿刺針207の露出を規制し安全である。 The first arm 209 prevents the lancet body 203 from moving forward. The distal end portion of the first arm 209 is exposed from the puncture needle holder 201. When the lancet body 203 is about to move forward, the distal end portion of the first arm 209 engages with the opening end portion 214 (see FIG. 5) portion of the puncture needle holder 201 and restricts forward movement. With this configuration, unlike the normal procedure, the exposure of the puncture needle 207 is restricted and safe even if the protective cap 202 is removed before the puncture needle cartridge 105 is attached to the puncture apparatus main body 101.
 第2アーム210の先端部は、穿刺針ホルダ201内にとどまる。 The tip of the second arm 210 remains in the puncture needle holder 201.
 〔第1の状態から第2の状態への遷移状態〕
 上述した<第1の状態>と<第2の状態>との間には、(1)穿刺針カートリッジ105装着時(図6参照)、(2)保護キャップ202分離(図7参照)が存在する。
[Transition state from the first state to the second state]
Between <first state> and <second state> described above, (1) when puncture needle cartridge 105 is mounted (see FIG. 6), (2) separation of protective cap 202 (see FIG. 7) exists. To do.
 先に第1の状態から第2の状態へと移行する過程として(1)、(2)について説明する。 First, (1) and (2) will be described as a process of shifting from the first state to the second state.
 (1)穿刺針カートリッジ105装着時(図6参照)
 第1アーム209の先端部は、穿刺針カートリッジ105を穿刺装置本体101に装着する動作に応じて、ベースメカ102(図6参照)の端面に案内されてランセット本体203の軸心方向へ移動する。第1アーム209の先端の最終位置は、ベースメカ102の内側である。
(1) When the puncture needle cartridge 105 is mounted (see FIG. 6)
The distal end portion of the first arm 209 is guided by the end surface of the base mechanism 102 (see FIG. 6) and moves in the axial direction of the lancet body 203 in accordance with the operation of mounting the puncture needle cartridge 105 to the puncture apparatus body 101. The final position of the tip of the first arm 209 is inside the base mechanism 102.
 第2アーム210の先端部は、穿刺針ホルダ201内にとどまる。 The tip of the second arm 210 remains in the puncture needle holder 201.
 (2)保護キャップ202分離(図7参照)
 第1アーム209の先端部及び第2アーム210の先端部の動作変化はない。
(2) Separation of protective cap 202 (see FIG. 7)
There is no change in the operation of the tip of the first arm 209 and the tip of the second arm 210.
〔第2の状態〕
 次に、<第2の状態>について図8を用いて説明する。
[Second state]
Next, <second state> will be described with reference to FIG.
 穿刺ボタン108を押すことによって、穿刺針207の先端が穿刺針ホルダ201から突出して皮膚を穿刺する。それに伴い、第1アーム209の先端部も前進し、穿刺針ホルダ201の内部に入る。第1アーム209の先端部は、その後、プランジャ103が穿刺バネの自由長の位置まで後退した際に止まる。止まった時の穿刺針ホルダ201内部における第1アーム209の先端部の位置は、穿刺針カートリッジ105装着時の位置よりも前方でかつ穿刺針ホルダ201の内部である。 By pressing the puncture button 108, the tip of the puncture needle 207 protrudes from the puncture needle holder 201 and punctures the skin. Accordingly, the distal end portion of the first arm 209 also advances and enters the puncture needle holder 201. Thereafter, the distal end portion of the first arm 209 stops when the plunger 103 is retracted to the position of the free length of the puncture spring. The position of the distal end portion of the first arm 209 inside the puncture needle holder 201 when stopped is in front of the position when the puncture needle cartridge 105 is mounted and inside the puncture needle holder 201.
 この時、第1アーム209の先端部および第2アーム210の先端部は、穿刺針ホルダ201内にとどまる。この穿刺後の状態を第2の状態とする。 At this time, the distal end portion of the first arm 209 and the distal end portion of the second arm 210 remain in the puncture needle holder 201. This state after puncturing is defined as a second state.
 〔第2の状態から第3の状態への遷移状態〕
 以下、<第2の状態>の後に後述の<第3の状態>へと続く廃棄時(図9参照)の一連動作について、便宜上その1からその4に分割して説明する。

 廃棄用部材106が穿刺針ホルダ201のみを押す動作に伴って、穿刺針ホルダ201のみが穿刺針207先端方向に動くが、ランセット本体203は移動しない。この時に、穿刺針ホルダ201が、開口端部214内側の傾斜にそって第1アーム209の先端部をランセット本体203の軸心方向に弾性変形させながら動く。そして第1アーム209の先端部が、開口端部214(図5参照)を通過すると、第1アーム209の先端部が穿刺針ホルダ201から露出する。
Disposal 1
As the discarding member 106 pushes only the puncture needle holder 201, only the puncture needle holder 201 moves toward the distal end of the puncture needle 207, but the lancet body 203 does not move. At this time, the puncture needle holder 201 moves while elastically deforming the distal end portion of the first arm 209 in the axial direction of the lancet body 203 along the inclination inside the opening end portion 214. When the distal end portion of the first arm 209 passes through the opening end portion 214 (see FIG. 5), the distal end portion of the first arm 209 is exposed from the puncture needle holder 201.
 この間、第2アーム210の先端部は、穿刺針ホルダ201内にとどまっている。 During this time, the tip of the second arm 210 remains in the puncture needle holder 201.
 廃棄時その2
 廃棄用部材106は、前述の廃棄時その1での押す動作を継続し、穿刺針ホルダ201がさらに前方へ移動するが、第1アーム209の先端部位置はそのままとどまる。
2 at the time of disposal
The discarding member 106 continues the pushing operation of the first at the time of discarding, and the puncture needle holder 201 moves further forward, but the position of the distal end portion of the first arm 209 remains as it is.
 このさらなる前方への移動によって、今度は、穿刺針ホルダ201が、開口端部214内側の傾斜にそって第2アーム210の先端部をランセット本体203の軸心方向に弾性変形させながら動く。 This further forward movement causes the puncture needle holder 201 to move while elastically deforming the tip of the second arm 210 in the axial direction of the lancet body 203 along the inclination of the inside of the opening end 214.
 〔第3の状態〕
 廃棄時その3
 そして第2アーム210の先端部が、開口部211の前端である開口端部214を通過すると、弾性変形が元に戻りながら第2アーム210の先端部が穿刺針ホルダ201から露出する。この状態を<第3の状態>とする。
[Third state]
Disposal 3
When the distal end portion of the second arm 210 passes through the opening end portion 214 that is the front end of the opening portion 211, the distal end portion of the second arm 210 is exposed from the puncture needle holder 201 while the elastic deformation is restored. This state is referred to as <third state>.
 廃棄時その4
 第1アーム209のつけね後端部とガイド215後端部の少なくとも一方が穿刺針ホルダ201開口部211の後端に係合して、廃棄用部材106の力がランセット本体203に加わり、チャッキング部206がプランジャ103から解放され、穿刺針カートリッジ105が穿刺装置本体101から廃棄される。
4 at the time of disposal
At least one of the rear end of the first arm 209 and the rear end of the guide 215 engages with the rear end of the puncture needle holder 201 opening 211, and the force of the disposal member 106 is applied to the lancet body 203, thereby The king portion 206 is released from the plunger 103, and the puncture needle cartridge 105 is discarded from the puncture device main body 101.
 この間は、第1アーム209の先端部及び第2アーム210の先端部の動作変化はない。 During this time, there is no change in the operation of the tip of the first arm 209 and the tip of the second arm 210.
 以上、<第1の状態>、<第2の状態>、<第3の状態>における第1アーム209及び第2アーム210の動作について述べた。続いて、「廃棄後の穿刺針207の露出防止又は再使用防止」状態にある時の第1アーム209及び第2アーム210の動作について述べる。 The operation of the first arm 209 and the second arm 210 in the <first state>, <second state>, and <third state> has been described above. Next, the operation of the first arm 209 and the second arm 210 when in the “prevented exposure or reuse prevention of the puncture needle 207 after disposal” state will be described.
 廃棄後の穿刺針207の露出防止は、穿刺装置本体101への穿刺針カートリッジ105の再装着がない場合について説明し、廃棄後の穿刺針207の再使用防止は、穿刺装置本体101への穿刺針カートリッジ105の再装着がある場合について説明する。 The prevention of exposure of the puncture needle 207 after disposal will be described in the case where the puncture needle cartridge 105 is not remounted to the puncture apparatus main body 101, and the reuse of the puncture needle 207 after disposal is prevented from puncturing the puncture apparatus main body 101. A case where the needle cartridge 105 is remounted will be described.
 〔廃棄後の穿刺針207の露出防止〕
 穿刺装置本体101への穿刺針カートリッジ105の再装着がない場合
 穿刺針207を露出する方向へランセット本体203が動いた時、第2アーム210の先端部が穿刺針ホルダ201に係合する。これにより、ランセット本体203が前方へ移動することを規制し、穿刺針207が穿刺針ホルダ201から露出することを防止できる。さらに、第2アーム210が破損した場合であっても、第1アーム209の先端部が穿刺針ホルダ201に係合する。このように廃棄後には、常に第1アーム209および第2アーム210の2種類のアームが穿刺針207の露出防止のために機能することにより、より安全な製品とすることができる。
[Preventing exposure of puncture needle 207 after disposal]
When the puncture needle cartridge 105 is not reattached to the puncture device main body 101 When the lancet main body 203 moves in the direction in which the puncture needle 207 is exposed, the tip of the second arm 210 is engaged with the puncture needle holder 201. This restricts the lancet body 203 from moving forward and prevents the puncture needle 207 from being exposed from the puncture needle holder 201. Furthermore, even if the second arm 210 is damaged, the tip of the first arm 209 is engaged with the puncture needle holder 201. Thus, after disposal, the two types of arms, the first arm 209 and the second arm 210, always function to prevent the puncture needle 207 from being exposed, so that a safer product can be obtained.
 〔廃棄後の穿刺針207の再使用防止〕
 穿刺装置本体101への穿刺針カートリッジ105の再装着がある場合(リキャップなし)
 使用済みランセットの再使用は、禁止されている。それにもかかわらず、ユーザが穿刺装置本体101への穿刺針カートリッジ105の再装着をした場合には、図9Bに示すように、第2アーム210の先端部と穿刺針ホルダ201が係合することによって、ランセット本体203が前方へ移動することを規制し、再使用できない。
[Preventing reuse of puncture needle 207 after disposal]
When the puncture needle cartridge 105 is reattached to the puncture device main body 101 (without recap)
Reuse of used lancets is prohibited. Nevertheless, when the user reattaches the puncture needle cartridge 105 to the puncture device main body 101, the tip of the second arm 210 and the puncture needle holder 201 are engaged as shown in FIG. 9B. Therefore, the lancet body 203 is restricted from moving forward and cannot be reused.
 以上詳細に説明したように、本実施の形態によれば、穿刺針カートリッジ105を構成するランセット204は軸方向の互いに異なる位置に、弾性変形が可能な第1アーム209と第2アーム210とを有し、穿刺針カートリッジ105は、第1アーム209の先端部が穿刺針ホルダ201から露出して、ランセット本体203の移動を規制する<第1の状態>と、第1アーム209の先端部と、第2アーム210の先端部とが穿刺針ホルダ201内に納まって、ランセット本体203が穿刺針207の軸方向に移動可能な<第2の状態>と、第1アーム209の先端部と第2アーム210の先端部がそれぞれ、穿刺針ホルダ201から露出して、ランセット本体203の移動を規制する<第3の状態>とを取り得る。この構成により、患者が使用済み穿刺針カートリッジ105を再装着しても再度の穿刺動作を防止することができる。 As described above in detail, according to the present embodiment, the lancet 204 constituting the puncture needle cartridge 105 has the first arm 209 and the second arm 210 that can be elastically deformed at different positions in the axial direction. The puncture needle cartridge 105 includes a distal end portion of the first arm 209 that is exposed from the puncture needle holder 201 to restrict the movement of the lancet body 203, and a distal end portion of the first arm 209. The second arm 210 and the distal end of the first arm 209 are accommodated in the puncture needle holder 201 so that the lancet body 203 can move in the axial direction of the puncture needle 207, and the distal end of the first arm 209 The distal end portions of the two arms 210 are exposed from the puncture needle holder 201 and can take <third state> in which the movement of the lancet body 203 is restricted. With this configuration, even if the patient re-installs the used puncture needle cartridge 105, the puncture operation can be prevented again.
 また、使用後の穿刺針カートリッジ105において、第2アーム210の先端部あるいは第1アーム209の先端部が穿刺針ホルダ201と当接することで使用後の穿刺針207の露出を防止することができる。 Further, in the puncture needle cartridge 105 after use, the distal end portion of the second arm 210 or the distal end portion of the first arm 209 abuts against the puncture needle holder 201, thereby preventing the puncture needle 207 after use from being exposed. .
 また、使用後のランセット本体203の軸方向の動きを規制する第1アーム209及び第2アーム210を設けているため、第2アーム210が破損することがあっても、破損しなかった他方のアームにより穿刺針の露出を防止でき、より一層安全である。 In addition, since the first arm 209 and the second arm 210 that restrict the axial movement of the lancet body 203 after use are provided, even if the second arm 210 may be damaged, the other arm that has not been damaged The arm can prevent the puncture needle from being exposed, making it even safer.
 本実施の形態では、第1アーム209あるいは第2アーム210は、アームが2種類あることで、再使用防止機能を強化することができる。また、使用後の穿刺針207の露出防止も強化することができる。 In the present embodiment, the first arm 209 or the second arm 210 has two types of arms, so that the reuse prevention function can be enhanced. Further, prevention of exposure of the puncture needle 207 after use can be enhanced.
 また、アーム形状において、アームから分岐した突起部212を設けたことで、より穿刺針ホルダ201と係合したり、よりアームが開きにくくなったりするため、再使用及び露出の防止に役立つ効果がある。 In addition, in the arm shape, by providing the protruding portion 212 branched from the arm, the arm is more easily engaged with the puncture needle holder 201 and the arm is more difficult to open. is there.
 特に、本実施の形態では、保護キャップ202をリキャップされ、かつ穿刺装置本体101に装着されても、再使用できないようにすることができるという特有の効果がある。 Particularly, in the present embodiment, there is a specific effect that even if the protective cap 202 is recapped and attached to the puncture apparatus main body 101, it cannot be reused.
 なお、本実施の形態では、第1アーム209と第2アーム210を2個ずつ配置し、等角度(180度)の位相に配置した例について説明したが、第1アーム209と第2アーム210が、2個であること、等角度であることは、それぞれ限定されない。 In the present embodiment, an example in which two first arms 209 and two second arms 210 are arranged at equal angles (180 degrees) has been described. However, the first arm 209 and the second arm 210 are described. It is not limited that there are two or equal angles.
 また、第1アーム209及び第2アーム210が、傾斜部209a,210aを有すること、第2アーム210が、突起部212を有することは、それぞれ限定されない。 Further, it is not limited that the first arm 209 and the second arm 210 have the inclined portions 209a and 210a, and the second arm 210 has the protruding portion 212, respectively.

(Embodiment 2)
FIG. 11 is a perspective view of the protective cap and lancet body of the puncture needle cartridge according to Embodiment 2 of the present invention. The same components as those in FIG. 4 are denoted by the same reference numerals, and description of overlapping portions is omitted.
 図11において、ランセット304は、ランセット本体203の軸周りの位相が異なった位置に配置される第1アーム309と第2アーム310とを有する。 11, the lancet 304 has a first arm 309 and a second arm 310 that are arranged at positions where phases around the axis of the lancet body 203 are different.
 図11に示すように、実施の形態2では、第1アーム309と第2アーム310がそれぞれ90度の位相差を持った位置に2個ずつ配置されており、第1アーム309、第2アーム310ともに、実施の形態1と同じく等角度(180度)の位相に配置されている。 As shown in FIG. 11, in the second embodiment, two first arms 309 and two second arms 310 are arranged at positions having a phase difference of 90 degrees, and the first arm 309 and the second arm Both 310 are arranged at the same angle (180 degrees) as in the first embodiment.
 また、第1アーム309と第2アーム310の先端部のチャッキング部206側に、傾斜部309a,310aを有している。 In addition, inclined portions 309 a and 310 a are provided on the chucking portion 206 side of the tip portions of the first arm 309 and the second arm 310.
 また、第2アーム310には、突起部311が設けられている。突起部311は、第2アーム310の先端部から穿刺方向に突出した形状を有する。 Further, the second arm 310 is provided with a protrusion 311. The protrusion 311 has a shape protruding from the distal end portion of the second arm 310 in the puncture direction.
 実施の形態1の第1アーム209と第2アーム210とが同位相に配置されていたのに対し、実施の形態2では、第1アーム309と第2アーム310との位相が異なる。この時、ユーザによる誤操作によって容易に全てのアームを内側に変形させることを防止する。 While the first arm 209 and the second arm 210 of the first embodiment are arranged in the same phase, in the second embodiment, the phases of the first arm 309 and the second arm 310 are different. At this time, it is possible to prevent all the arms from being easily deformed inward by an erroneous operation by the user.
 実施の形態2によれば、実施の形態1の効果に加えてさらに以下の効果がある。すなわち、実施の形態1の第1アーム209及び第2アーム210のように、アームが同位相の場合には、廃棄後、このアームを指で掴んで、無理な操作をすると針が露出する場合が考えられる。これに対して、実施の形態2では、第1アーム309と第2アーム310の位相が90度ずらすことで、上記のような操作が非常に難しくなり、露出防止により効果がある。 According to the second embodiment, in addition to the effects of the first embodiment, the following effects are further obtained. That is, when the arms are in the same phase as in the first arm 209 and the second arm 210 of the first embodiment, the needle is exposed when the arm is grasped with a finger after being discarded and an unreasonable operation is performed. Can be considered. On the other hand, in the second embodiment, since the phases of the first arm 309 and the second arm 310 are shifted by 90 degrees, the operation as described above becomes very difficult, and it is more effective in preventing exposure.
 なお、本実施の形態では、第1アーム309と第2アーム310がそれぞれ90度の位相差を持った位置に2個ずつ配置し、等角度(180度)の位相に配置した例について説明したが、第1アーム309と第2アーム310が、2個であること、90度の位相差であること、等角度であることは、それぞれ限定されない。 In this embodiment, an example is described in which two first arms 309 and two second arms 310 are arranged at positions having a phase difference of 90 degrees, and are arranged at an equiangular (180 degrees) phase. However, it is not limited that there are two first arms 309 and two second arms 310, a phase difference of 90 degrees, and equiangularity.
 また、第1アーム309及び第2アーム310が、傾斜部309a,310aを有すること、第2アーム310が、突起部311を有することは、それぞれ限定されない。 Further, it is not limited that the first arm 309 and the second arm 310 have the inclined portions 309a and 310a, and the second arm 310 has the protruding portion 311, respectively.

 一方、図16に示すように、穿刺針カートリッジ705が使用済みの状態では、第2アーム210は、穿刺針ホルダ201から露出し、第2アーム210のホルダ係合部213が、穿刺針ホルダ201の開口端部214と係合する。 On the other hand, as shown in FIG. 16, when the puncture needle cartridge 705 has been used, the second arm 210 is exposed from the puncture needle holder 201, and the holder engaging portion 213 of the second arm 210 is moved to the puncture needle holder 201. Engaging with the open end 214.
 これにより、ランセット本体203が穿刺針の軸方向(穿刺方向)に移動することが規制される。 This restricts the movement of the lancet body 203 in the axial direction (puncture direction) of the puncture needle.
 このため、ユーザが、使用済みの穿刺針カートリッジ705のランセット本体203を押しても、穿刺針207が穿刺針ホルダ201から露出しない。 Therefore, even if the user presses the lancet body 203 of the used puncture needle cartridge 705, the puncture needle 207 is not exposed from the puncture needle holder 201.
 また、ユーザが、使用済みの穿刺針カートリッジ705を穿刺装置本体101に再装着し、穿刺ボタン108(図1参照)を押し下げても、ランセット本体203が穿刺針207の軸方向(穿刺方向)に移動することが規制され、再度穿刺されることがない。 Further, even if the user remounts the used puncture needle cartridge 705 to the puncture apparatus main body 101 and depresses the puncture button 108 (see FIG. 1), the lancet main body 203 remains in the axial direction (puncture direction) of the puncture needle 207. It is restricted from moving and is not punctured again.
 このように、本実施の形態によれば、穿刺針カートリッジ705が使用済みの状態において、ランセット本体203の移動を規制する第2アーム210を設けることにより、使用済み穿刺針カートリッジ705の再使用及び使用済み穿刺針カートリッジ705の穿刺針207の露出を防止することができる。 As described above, according to the present embodiment, in the state where the puncture needle cartridge 705 has been used, the second arm 210 that restricts the movement of the lancet body 203 is provided, so that the used puncture needle cartridge 705 can be reused. Exposure of the puncture needle 207 of the used puncture needle cartridge 705 can be prevented.
 さらに、図16に示すように、使用済みの状態で、ホルダ係合部213が穿刺針ホルダ201を挟むように、ホルダ係合部213を二股に分かれた形状とすることにより、穿刺針207の軸方向に垂直な方向の外側から第2アーム210を押圧しても、第2アーム210が開口部211から穿刺針ホルダ201の内側に入り込まないようにすることができる。 Furthermore, as shown in FIG. 16, the holder engaging portion 213 is formed in a bifurcated shape so that the holder engaging portion 213 sandwiches the puncture needle holder 201 in the used state, thereby Even if the second arm 210 is pressed from the outside in the direction perpendicular to the axial direction, the second arm 210 can be prevented from entering the inside of the puncture needle holder 201 from the opening 211.
 なお、ホルダ係合部213の形状は図16に示した形態に限らず、他の実施の形態において開示した第2アームの形状等、第2アーム210が開口部211から穿刺針ホルダ201の内側に入り込まないようにすることができるものであれば他の形状であってもよい。 Note that the shape of the holder engaging portion 213 is not limited to the shape shown in FIG. 16, and the second arm 210 extends from the opening 211 to the inside of the puncture needle holder 201, such as the shape of the second arm disclosed in other embodiments. Other shapes may be used as long as they can be prevented from entering.
 以上の説明は本発明の好適な実施の形態の例証であり、本発明の範囲はこれに限定されることはない。 The above description is an illustration of a preferred embodiment of the present invention, and the scope of the present invention is not limited to this.
 上記各実施の形態では穿刺針カートリッジ及び穿刺装置という名称を用いたが、これは説明の便宜上であり、穿刺器具、穿刺具等であってもよいことは勿論である。 In the above embodiments, the names puncture needle cartridge and puncture device are used. However, this is for convenience of explanation, and it is needless to say that the puncture device, the puncture device, and the like may be used.
