Abstract

The utility model relates to a disposable multipurpose lancet which is mainly used for medical clinical blood sampling of blood routine examinations and acupoint pricking bloodletting. The utility model is composed of a needle handle 1, a needle 2, and a needle cap 14 is attached to the utility model. The utility model is characterized in that the needle handle 1 is in a tapered tube shape, and is composed of the upper section of the needle handle 3 and the lower section of the needle handle 4, a step 5 is arranged between the two sections, a hole 6 is arranged in the upper section of the needle handle 3, a hole 7 is arranged in the lower section of the needle handle, the hole 6 is communicated with the hole 7, and neck is arranged at the communicated point. The needle 2 is composed of an upper section of the needle bar 9, a lower section of the needle bar 10, and a tip of the needle 11. Compared with the needle handle 1, the needle cap 14 is not provided with the hole 7, a solid 15 is arranged at the position of the hole 7, and other structures are completely the same. The upper section of the needle bar 9 is inserted and sheathed in the hole 7.

Description

Multipurpose lancet

This utility model relates to a medical apparatus and instruments, is used for the lancet of using that clinical blood routine examination blood sampling is used or acupuncture point pricking method blood-letting is used more.

Present clinical blood routine examination blood sampling is adopted directly to contact wound with the blood routine examination sample sipper tube behind the thorn blood such as some water-color paintbrush points and suck blood more; The traditional three edged needle of the traditional Chinese medical science is adopted in acupuncture point pricking method blood-letting more.All be to reuse through sterilization or after disinfecting.So the anxiety of cross infection is all arranged.So far the two does not see that as yet a kind of ideal needle set emerges.

The purpose of this utility model is: provide a kind of be convenient to disposable; Can also be used as the lancet of using of acupuncture point pricking method blood-letting as avoiding the blood routine examination sample sipper tube directly to touch the sleeve gasket of wound again as the blood taking needle of clinical blood routine examination more.

Below in conjunction with accompanying drawing, this utility model is described in detail:

Fig. 1 is this utility model front view.

Fig. 2 is a pin medicated cap front view.

With reference to accompanying drawing: a kind of multiplex lancet is made up of handle 1, pin 2, and has been installed with pin cap 14; It is characterized in that: needle handle 1 is tubular for taper, is made up of needle handle epimere 3 needle handle hypomeres 4, and there is step 5 two sections centres, and needle handle epimere 3 is interior porose 6, and needle handle hypomere 4 is

interior porose

7, and 6 holes, hole are communicated with hole 7, and connectivity part has eck 8; Pin 2 is made up of shank epimere 9, shank hypomere 10, needle point 11; Pin cap 14 is compared with needle handle 1, and this is located to solid 15 except there not being hole 7, and other structures are just the same; And shank epimere 9 sleeves are in hole 7. And shank epimere 9 is truncated cone-shaped, and shank hypomere 10 is cylindrical, and needle point 11 is triangular prism shaped. And the degree of depth in hole 6 is longer than the total length of needle handle hypomere 4 and shank hypomere 10 and needle point 11; And but in the blood routine examination sample sipper tube patchhole 6, when it was inserted to eck 8, a bit of corresponding site formation was movingly more than 8 for hole 6 and blood routine examination sample sipper tube and aperture 12 and eck. And many multiplex lancets is mutual when nestable, and after needle handle hypomere 4 patchholes 6 were interior, hole wall 13 was the plane with step 5 and coincide, and needle handle hypomere 4 forms movingly with hole 6 epimeres. And hole 7 is truncated cone-shaped, behind shank epimere 9 patchholes 7, has a bit of eck 8 that passes to enter in the hole 6, and this moment, shank epimere 9 formed movingly with hole 7.

Below in conjunction with embodiment and the simple summary of using method operation principle of the present utility model.

With reference to accompanying drawing: but needle handle 1 injection mo(u)lding, pin 2 stainless steel silk punch forming.Will be more than many nestable with lancet, bottom one put pin medicated cap 14, topmost a sticking one deck is foretold membrane closure hole 6, uses the bag film asepsis vacuum packing after the sterilization treatment.

During use, take off pin medicated cap 14 earlier, to use lancet more, and use and once to take off one and abandon it, simultaneously the pin cap sleeve be covered on that newly to expose pin 2 still untapped many with on the lancet, prevent to pollute, when using last, throw off the thin film on the aperture 12, in pin medicated cap 14 patchholes 6, the pin medicated cap 14 like this, played the effect of holding length of picking up that increases a needle handle 1 the most not again.Be used as the blood routine examination blood sampling time spent, the lancets of using that take off behind the thorn blood can be enclosed within on the blood routine examination sample sipper tube more, insert the back pin and supported out, needle handle 1 is limited on the blood routine examination sample sipper tube then.Because the feature of hole 6, hole 7, eck 8, during sampling operation, hole 7 forms the isolation distance of routine blood test sample sipper tube and skin wounds, and hole 7 a picture horn mouth cover wound simultaneously, and hole 7 forms a negative pressure cavity, finishes and sucks blood.After operation is finished, take off from the blood routine examination sample sipper tube and to abandon it.

Because needle point 11 is triangular prism shaped, so can use the different dynamics of weight according to patient's skin thickness, thorn is created suitable wound and oozing of blood amount, so not only can make the blood routine examination blood taking needle but also can make acupuncture point pricking method fleams and use.

In sum, this utility model has been realized the purpose of design that proposes.
