Description
Technical field
The present invention relates to a kind of instrument that detects blood oxygen saturation and pulse, refer in particular to and a kind of testing circuit and display device are integrated into finger type instrument for detecting sphygmus and blood oxygen saturation on the soft fingerstall.
Background technology
Pulse and blood oxygen saturation are important human body physiological parameters.Instrument for detecting sphygmus and blood oxygen saturation one adopt the method for Photoelectric Detection to measure human pulse and blood oxygen saturation, and detection position commonly used is finger.Compound mode according to detection probe and display part, can be divided into desk-top, hand held and refer to formula, wherein blood oxygen probe desk-top and hand held is to link to each other with main frame by a long wire, refers to that formula then is that blood oxygen probe and detection and display part are integrated.
Finger formula blood oxygen instrument and hand held and table type photo ratio, smaller and more exquisite, easy to use.Therefore, going for hospital and family, also is that the sports enthusiast is selected more and more.
According to detecting principle, finger formula blood oxygen instrument will reach good performance, must guarantee during use following some: the one, finger must contact closely with photoelectricity testing part, can owing to human motion generation point and photoelectric device between relatively moving, not cause that much noise is arranged in the detection signal; The 2nd, blood oxygen instrument is wanted to shield surrounding environment light, in order to avoid testing result is impacted; The 3rd, the clamping force of finger is wanted suitably, it is bad that too conference causes the finger blood supply, artificially produces weak perfusion, and too pine is then pointed and can move, and produces motion artifacts; The 4th, if blood oxygen instrument is to use in hospital, then can be cleaned by ethanol or other sterilised liqs and sterilize, to prevent cross infection; Five is that good antidetonation and shatter-resistant performance will be arranged.
Finger formula blood oxygen instrument in the market has two classes, and the first kind is the finger formula blood oxygen instrument of clip structure, and such as United States Patent (USP) the 6th, 654, No. 621 and Chinese invention patent application all disclose this type of blood oxygen instrument for No. 200610144965.3.Its structure one by upper and lower cabinet, flexible glue pad, elastic clamping structure, luminous and receive structure, testing circuit and display device and form.Wherein, upper and lower cabinet connects by spring assembly, consists of a clip structure, and by pressing an end, the other end can open.During use the upper and lower shell of clip is opened, finger is placed on the flexible glue pad, and spring structure can be fixed on the flexible glue pad by finger, is presented on the display screen of loam cake after by Photoelectric Detection blood oxygen levels being detected.
Equations of The Second Kind product such as Pulseox 550 (SPO MEDICAL company product) are by upper and lower cabinet, soft fingerstall, luminous and receive structure, testing circuit and display device and form.Wherein, an end of upper and lower cabinet is fixed together by fixture.Push the both sides of soft fingerstall during use with hands, soft fingerstall is opened, finger inserts in the soft fingerstall.The finger that inserts soft fingerstall produces an extruding to upper and lower shell, and upper and lower shell can produce a compressing power to finger conversely, thereby can finger is fixing.
By finding that relatively the difference of first kind product and Equations of The Second Kind product is, adopts movable connection between the upper and lower shell of first kind product, and is fixed connection structure between the upper and lower shell of Equations of The Second Kind product.First kind product is to guarantee can both clamp after the finger of different thicknesses is put into by a spring assembly, the Equations of The Second Kind product is by a soft fingerstall and finger contact, the upper and lower shell of extruding after the soft fingerstall expansion, because upper and lower shell has an end to fix, therefore, can produce a pressure to finger, guarantee that by this pressure finger contacts well with photoelectric device.
Yet in fact the structural design of this two series products is difficult to reach the purpose of guaranteeing to point with the photoelectric device close contact.In the first kind product, the people of thick fingers is difficult to obtain consistent pressure with pointing thin people, is easy to produce too pine or too tight phenomenon.In addition, adopt the structure of spring clip, after finger is put into, cause easily inhomogeneous to finger pressure.In the Equations of The Second Kind product, thick finger has very large constriction, and thin finger can feel that blood oxygen instrument is loosening as soon to fall down.
The upper and lower shell of first kind product is open, therefore, can not effectively block surrounding light and enter probe, and this is so that this series products possibly can't use under outdoor sunlight.
In addition, therefore first kind product, can't carry out disinfection to the flexible glue pad owing to can't seal between flexible glue pad and the shell.Also not sealing between photoelectric device and the soft fingerstall also is open between soft fingerstall and the shell simultaneously in the soft fingerstall of Equations of The Second Kind product, therefore also can't carry out good sterilization.Therefore, this two series products all is unfavorable for using in the hospital.
First kind product cabinet is easy to fall apart or ftracture after being subject to external force collision.The Equations of The Second Kind product casing also is plastic material, and this is also so that blood oxygen instrument is easy to occur breaking damage in the situation that drops or clash into, and perhaps causes inner member, circuit impaired.Therefore, be necessary existing product is improved, improve its shock resistance and shatter-resistant performance.
Summary of the invention
The object of the invention is to solve existing finger formula blood oxygen instrument finger is clamped that property is poor, poor to the surround lighting light-proofness, shatter-resistant is poor, water proofing property is poor, wears the problems such as comfort level is poor, a kind of finger type instrument for detecting sphygmus and blood oxygen saturation based on soft fingerstall is provided.
For achieving the above object, the present invention proposes following technical scheme:
