Abstract

The utility model discloses an asymmetric hemostatic clamp comprising a clamp body, which is characterized in that the clamp body comprises two arc linear clamp arms with an oblate clamp and an upper and a lower asymmetric clamp body on a handle, the clamp arm of the lower clamp body is longer than the upper clamp body, a prominent rotation shaft fastener and a rotary groove engaged with the rotation shaft fastener are respectively jointly arranged at both sides of the assembly between the upper and lower clamp body, the upper and lower clamp body are mutually clipped by the rotation shaft fastener, two fixing grooves each assembled with an elastic circlip are respectively arranged on the clamp arms of the corresponding positions on the upper end face of the upper clamp body and the lower end face of the lower clamp body, and the elastic circlips are crossed through two ends of a spacing hole arranged on the handle of the clamp body and are respectively clipped in the fixing groove of the elastic circlips. The utility model claims for the asymmetric type of the upper and the lower clamp body, when the push is needless the clamp arm of the lower clamp body is longer for dispersing the stress and the clamp of the upper clamp body is need to push the needle hole for centralizing the stress. The clipping strength of the clamp can be adjusted by the replacement of elastic circlips. The utility model has simply structure, aesthetic appearance and convenient utilization.

Description

Asymmetric hemostatic clamp

Technical field:

This utility model relates to medical equipment, is used for the asymmetric hemostatic clamp of pin hole hemostasis usefulness when especially a kind of blood drawing, blood transfusion, transfusion.

Background technology:

At present, various big hospital is when blood drawing, blood transfusion, transfusion, and major part all is to adopt the rubber leather hose to tighten arm, stops the above blood of arm and flows toward the back of the hand or finger, have an acupuncture treatment then, and this hemostasis mode troublesome poeration, the colligation tension can produce pain.In blood drawing, blood transfusion, when transfusion finishes to extract syringe needle, normally adopt absorbent cotton or adhesive bandage to push the mode of pin hole to the hemostasis of pin hole, make blood stay the actual time and solidify at wound, reach the hemostatic purpose.Particularly when transfusing blood in a large number or donating blood, because pin hole is excessive, the wound that syringe needle causes is big; the blood transfusion time is long, and blood is difficult for solidifying, and wants the pressing hole about 15 minutes usually; even the longer time; after massive blood loss, blood transfusion, transfusion, under people's health and the bad situation, also want oneself push down the another hands with absorbent cotton or adhesive bandage with a hands; regular meeting feels to push finger and aches; psychentonia, inconvenience is movable again simultaneously, has increased people's misery.In order to solve the hemostasis problem of blood drawing, blood transfusion, transfusion, China Patent No. is: disclose a kind of " medical hemostatic folder " but it in 200420053859.0 the patent and mainly be the hemostasis before being used to draw blood, transfuse blood, infuse, and extracted the hemostasis behind the syringe needle after can not being used to draw blood, transfuse blood, infuse.

The utility model content:

The purpose of this utility model exactly will for the public provide a kind of simple in structure, easy to operate, use comfortable, the hemostasis of adversary or foot before can being used to draw blood, transfuse blood, infuse, the asymmetric hemostatic clamp of the pin hole hemostasis usefulness after being used to again draw blood, transfuse blood, infuse on adversary or the foot.

The purpose of this utility model is achieved through the following technical solutions:

This utility model comprises clamp, it is characterized in that: described clamp is by two asymmetrical upper clamp that are provided with oblate chuck circular arc line clevis arm and handgrip and lower clamp is equipped forms, the jig arm of lower clamp is longer than upper clamp, rotating shaft clamp that is provided with protrusion and the rotation groove that is complementary with the rotating shaft clamp are staggered respectively in the both sides, equipped place of upper clamp and lower clamp, upper clamp and lower clamp clamp mutually by the rotating shaft clamp, be respectively equipped with the holddown groove of equipped elastic circlip on the jig arm of the lower surface opposite position of the upper surface of upper clamp and lower clamp, elastic circlip passes upper clamp, the spacing hole two ends that is provided with on the handgrip of lower clamp is installed on upper clamp respectively, in the holddown groove of the elastic circlip that is provided with on the lower clamp.

In order to save material, concave surface can be arranged in the jig arm position of the lower surface of the upper surface of upper clamp and lower clamp, the upper and lower end face of upper clamp and lower clamp or wherein the one side the handgrip position can be arranged to concave surface, the jig arm of clamp and handgrip position also can be the planes.

During use, with hand live in, the handgrip of lower clamp mouthful opens folder, makes the chuck of upper clamp be pressed in the pin hole place that is stamped absorbent cotton or adhesive bandage on the arm then, unclamp handgrip and get final product.

Simple in structure, the good looking appearance of this utility model, when being clamped on finger or the arm, the profile staff grips the shape of pushing, because upper and lower clamp is made as asymmetric, long at the lower clamp of not pushing like this, can dispersive stress, and the chuck of upper clamp need be pushed pin hole, so need stress concentration.The folder power size of clip can have inflexible elastic circlip by replacing and regulate, and to reach energy hemostatic purpose, can the labor pain sense be not good again.

Description of drawings:

Fig. 1 is a side of the present utility model overall structure sketch map;

Fig. 2 is a vertical view of the present utility model.

Among the figure: the holddown groove of 1 upper clamp, 2 lower clamps, 3 elastic circlips, 4 rotating shaft clamps, 5 spacing holes, 6 elastic circlips.

The specific embodiment:

This utility model is made up of clamp and elastic circlip 3, clamp can adopt plastics or PVC material to fall to make and form, elastic circlip 3 can adopt stainless steel material to make, clamp is by two asymmetrical upper clamp 1 that are provided with oblate chuck circular arc line clevis arm and handgrip and 2 equipped compositions of lower clamp, the jig arm of lower clamp 2 is longer than upper clamp 1, rotating shaft clamp 4 that is provided with protrusion and the rotation groove that is complementary with rotating shaft clamp 4 are staggered respectively in the both sides, equipped place of upper clamp 1 and lower clamp 2, upper clamp 1 clamps mutually with rotating shaft clamp 4 with lower clamp 2, concave surface is arranged in the jig arm position of the lower surface of the upper surface of upper clamp 1 and lower clamp 2, on upper clamp 1 and the lower clamp 2, the lower surface or wherein the one side the handgrip position be arranged to concave surface, clamp is arranged to concave surface can save material, the corresponding medial surface of folder mouth of clamp handgrip is arranged to concave surface except that saving the material, a clamp handgrip folder mouthful corresponding lateral surface is controlled the position and is arranged to the scrobicula face and can also plays anti-skidding effect, on the jig arm of the lower surface opposite position of the upper surface of upper clamp 1 and lower clamp 2, be respectively equipped with the holddown groove 6 of equipped elastic circlip, be respectively equipped with spacing hole 5 on the handgrip of upper clamp 1 and lower clamp 2, round and elastic jump ring 3 passes in the holddown groove 6 that spacing hole 5 two ends are installed on elastic circlip respectively.
