Pulse pressing clip for finger

Abstract

The invention discloses a pulse pressing clip for a finger, which is used for treating blood collection of finger ends. The pulse pressing clip for the finger consists of a clip body (1) parallel to a jaw, a spring (2), inner side convex cross grain elastic plastic (3), outer side concave cross grain elastic plastic (4), a finger ring (5) and a rope (6). In the scheme, the inner side convex elastic plastic (3) at the jaw is designed according to finger end vessel anatomy characteristics and can form pressure areas in palmar surface and back surface venous return areas of the finger to effectively prevent peripheral blood return of the finger, so that blood is collected smoothly, the pain of a blood-collected person is reduced, and the physical labor of blood collection personnel is reduced; the friction between an operator and a blood collection extruded finger is reduced by the outer side concave cross grain elastic plastic (4); and the finger ring (5) makes the operator conveniently wear the pulse pressing clip in a hand, so that taking and placing frequencies and pollution are reduced.

Description

technical field [0001] The invention relates to a finger pressure pulse clip used for treating blood collection from finger tips, belonging to the technical field of medical products. Background technique [0002] Finger tip blood collection is to puncture the skin of the finger, and the blood collection personnel repeatedly squeeze the venous return area near the puncture point with their hands to make the blood flow out from the puncture point. When the squeezing force is insufficient, the blood flow out is slow and easy to coagulate, and blood collection cannot be completed quickly; when the squeezing force is too high, the collected blood is likely to be mixed with more tissue fluid, which affects the test results and increases the pain of the blood sampled. This manual repeated squeezing of blood collection will bring fatigue and soreness to the fingers of the blood collection personnel, and the long-term repeated extrusion actions of the blood collection personnel may ...

AI Technical Summary

Problems solved by technology

Wherein, if a medical cuff clip, a kind of cuff clip is used for finger tip blood collection, its curved clip arm does not conform to the anatomical characteristics of the arteriovenous vessels of the finger tip, and it is easy to contact the puncture point and cause pollution when the blood collection is completed and taken off; When the pulse clip is applied to the finger, it is small and still needs to adjust the nut to form the pressure, which is time-consuming and the operating space is too small
