Description

Die vorliegende Erfindung betrifft eine Insulinspritze des Typs "Pen" gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an insulin syringe of the "pen" type according to the preamble of the claim 1.

Es sind bereits seit einigen Jahren Insulinspritzen bekannt, welche die Form eines Schreibstiftes aufweisen, so daß sich bei diesen Geräten mittlerweile der englische Ausdruck "Pen" durchgesetzt hat (siehe US PS 4 592 745). Derartige Insulinpen besitzen dabei in ihrem mittleren Bereich eine auswechselbare Insulinpatrone, welche mit Hilfe eines in Längsrichtung beweglichen Kolbens jeweils vorgegebene Mengen von Insulin durch eine im vorderen Bereich angeordnete, ebenfalls auswechselbare Spritzennadel abgeben kann. Eine genaue Einstellung der gewünschten Menge des einzuspritzenden Insulins wird dabei mit Hilfe eines im hinteren Bereich der Insulinpen angeordneten Drehknopfes erreicht, mit welchem der Vorschub des beweglichen Kolbens der Insulinpatrone genau eingestellt wird.It's been a few years Insulin syringes known, which have the shape of a pen, so that with these devices meanwhile the English term "pen" has prevailed (see U.S. Patent 4,592,745). Such insulin pens have in their middle Area of a replaceable insulin cartridge, which can be longitudinal moving piston each predetermined amounts of insulin a replaceable syringe needle located in the front area can give up. An exact setting of the desired amount of the injected Insulin is made with the help of one in the back of the insulin pen Arranged knob reached with which the feed of the movable piston of the insulin cartridge is precisely adjusted.

Der Benutzer einer derartigen Insulinpen kann dabei die gewünschte Dosierung von einzuspritzendem Insulin auf zweierlei Weise überwachen:

  • – Durch Mitzählen der Verrasterungen des im hintern Bereich der Insulinpen angeordneten Drehknopfes, wobei eine einzelne Verrastung entweder ein oder zwei Insulineinheiten entspricht. Dieses Mitzählen der Verrastungen des Drehknopfes kann dabei sowohl mechanisch wie auch akustisch wahrgenommen werden. Und
  • – mit Hilfe einer elektrischen Analog- oder Digitalanzeige, welche die Anzahl der eingestellten Insulineinheiten optisch anzeigt. Dabei haben sich mittlerweile vor allem LED-Anzeigen durchgesetzt, weiche durch ein vorgegebenes Fenster die eingestellten Insulineinheiten in Form von Zahlen im dekadischen System wiedergeben.
The user of such an insulin pen can monitor the desired dosage of insulin to be injected in two ways:
  • - By counting the catches of the rotary knob arranged in the rear area of the insulin pen, a single catch corresponding to either one or two insulin units. This counting of the locking of the rotary knob can be perceived both mechanically and acoustically. And
  • - With the help of an electrical analog or digital display, which visually shows the number of insulin units set. In the meantime, LED displays have prevailed, which show the set insulin units in the form of numbers in the decade system through a given window.

Es hat sich nunmehr herausgestellt, daß bei Diabetikern, welche derartige Insulinpen über Jahre hinweg benutzen, aufgrund des schwankenden Zuckergehaltes der Gefäße Spätschäden auftreten, welche zu einem Nachlassen der Sehfähigkeit bis zum eventuellen Erblinden führen. Derartige Spätschäden des Auges werden dabei als "Retinopathie" bezeichnet.It has now been found that in diabetics, which such insulin pen about Use for years due to fluctuating sugar levels the vessels suffer late damage, which to a decrease in vision lead to eventual blindness. Such late damage to the The eyes are referred to as "retinopathy".

Ein Nachlassen der Sehfähigkeit bei Diabetikern hat zur Folge, daß derartige Patienten bei der Einstellung der von ihnen verwendeten Insulinpen das vorgesehene Anzeigefenster nur noch schlecht oder gar nicht mehr ablesen können, was dann die Gefahr einer Insulinüberdosierung hervorruft. Eine derartige Überdosierung bewirkt bei den jeweiligen Patienten Unterzuckerzustände, welche als "Hyperglykämie" bezeichnet werden. Da derartige Unterzuckerzustände zu spastischen Erscheinungsbildern und im Extremfall auch zu komatösen Zuständen führen, müssen Insulinüberdosierungen so weit wie möglich vermieden werden.A decrease in vision in diabetics has the consequence that such patients when hiring of the insulin pen they are using the intended display window can only read poorly or not at all, which then creates the danger of a Insulin overdose causes. Such an overdose causes hypoglycaemia in the respective patient, which as "hyperglycemia" be designated. Because such hypoglycemic conditions lead to spastic appearances and in extreme cases too comatose states to lead, have to Insulin overdoses as far as possible be avoided.

Um derartige unerwünschte Insulinüberdosierungen zu vermeiden, ist es somit bereits bekannt (siehe US PS 5 569 214), einen vergrößerten T-förmigen Griff vorzusehen, damit eine Verstellung des am hinteren Ende der Insulinpen vorgesehenen Drehknopfes auch von körperbehinderten Personen in zufriedenstellender Weise durchgeführt werden kann.To such undesirable insulin overdoses to avoid it is therefore already known (see US Pat. No. 5,569,214), an enlarged T-shaped handle provide for an adjustment of the at the rear end of the insulin pen provided rotary knob also by disabled people in can be performed satisfactorily.

Um die Ablesbarkeit der innerhalb eines Fensters angegebenen Insulineinheiten zu erleichtern, ist es ferner bekannt (siehe US PS 6 001 082), in einem gewissen Abstand des betreffenden Fensters eine Vergrößerungslinse vorzusehen, was bei sehgestörten Diabetikern eine gewisse Erleichterung der Benutzung derartiger Insulinpen ergibt.To ensure the readability of the inside a window insulin units is easier it is also known (see US Pat. No. 6,001,082), at a certain distance to provide a magnifying lens of the window in question, what in visually impaired Diabetics get some relief from using such Insulin pen results.

Unter Berücksichtigung dieses Standes der Technik ist es Aufgabe der vorliegenden Erfindung, die bereits bekannten Insulinpen derart weiterzubilden, daß selbst Personen mit eingeschränkter oder gar keiner Sehfähigkeit, so wie sie bei einer langjähriger Insulineinnahme häufig hervorgerufen wird, eine genaue Dosierung der einzuspritzenden Insulinmenge vornehmen können, so daß auf diese Weise ungewünschte Unter zuckerzustände mit den entsprechenden Krankheitssymptomen weitgehend zu vermeiden sind.Taking this state into account the technology is the object of the present invention, which already to further develop known insulin pens such that even people with restricted or even no eyesight, just like a long-time Insulin intake is common an exact dosage of the amount of insulin to be injected can make so that on this way unwanted Under sugar conditions to be largely avoided with the corresponding symptoms of the disease are.
