Description

A kind of infusion needle combination type fin

Technical field

This utility model belongs to medical product technical field, specifically relates to a kind of infusion needle combination type fin.

Background technology

In prior art, infusion needle generally includes connected tube for transfusion and puncture needle, puncture needle arranged outside sleeve pipe, near puncture needle, fin is provided with outside tube for transfusion, time medical personnel infuse to patient or take a blood sample, remove sleeve pipe, hand-held fin punctures, and then fin is attached to blend compounds cloth on patient skin and is fixed.In time infusing or blood sampling terminates; the needle point of transfusion needle is just outside exposed; often or stab medical personnel; easily cause the antibacterial of nurse or the infection of virus; in the industry to this has been a lot of research and improving; such as adopt syringe needle etc. that is type self-destroyed, self-locking, make syringe needle be not easy to stab medical personnel.But, while drawing attention to exposed syringe needle, also need to cause enough attention to the complexity in piercing process.

Fin of the prior art is fixed because needs are attached on patient skin, this just determines is in laminar substantially, when the hand-held fin of such medical personnel punctures, finger can only pinch the edge at fin, finger is determined by the thickness of fin with the contact area of fin, easy skidding, very not smoothly, there is certain difficulty in operation, so easily impact puncture effect, also the misery of patient can be increased, if increase the thickness of fin in order to finger when increasing gripping and the contact area of fin, then the sense of discomfort of patient can be increased again when being fixed fin.

Summary of the invention

Technical problem to be solved in the utility model is just to provide a kind of infusion needle combination type fin, contact area during finger grip can be increased, puncture procedure is smoothly convenient, and do not need the thickness increasing fin, while facilitating medical personnel to operate, also can ensure the comfort of patient, alleviate its misery.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of infusion needle combination type fin, comprise and to be arranged on outside tube for transfusion near the fin body of puncture needle rearward end and to be set in and to inject cover outside described fin body, described cover of injecting comprises two grip blocks and a forward block, described two grip blocks are clamped in the both sides of fin body respectively, and described forward block to be arranged between two grip blocks and to prop up fin body rearward end.

This utility model adopts compound mode, fin body can keep flake, and injecting cover before puncture procedure, be enclosed within fin this is external, increase its thickness, increase contact area during finger grip, make gripping more stable, puncture procedure is convenient, after puncture completes, cover will be injected and throw off, and make fin body be close to skin and be fixed.Like this, while facilitating medical personnel to operate, also can ensure the comfort of patient, alleviate its misery.

Preferably, described two form groove between grip block and forward block, are provided with layer of silica gel inside described groove.The gap that layer of silica gel can be filled up fin body and inject between cover, and slip between the two can be prevented, make to control puncture needle during operation more stable, prevent from skidding, alleviate the misery of patient.

Preferably, be provided with convex tendon inside described grip block, described fin body is provided with the through hole matched with convex tendon on relevant position, and the material of described forward block is elastomer.Material due to forward block is elastomer, there is certain elasticity, grip block can be broken into two with one's hands to both sides, under the elastic reaction of forward block, grip block automatic rebounding is adjacent on fin body sidewall, and convex tendon is through through hole, positioning action can be played, fin body is formed integrally with injecting overlap, prevents from skidding between the two, stability during raising puncture procedure.After puncture completes, then grip block being broken into two with one's hands to both sides, take off and inject cover, fin body is fixed, and the through hole on fin body can't to fixedly impacting.

Preferably, the described front end face of two grip blocks and the rear end face of forward block are circular arc concave surface.When medical personnel carry out puncture procedure, forefinger and middle finger are placed on respectively the front end face of two grip blocks, thumb is placed on the rear end face of forward block, three finger grip fins, can carry out puncture procedure easily, and above-mentioned three end faces are designed to circular arc concave surface, more meet ergonomics, more naturally comfortable when medical personnel are gripped, improve puncture success rate, effectively alleviate the misery of patient.

Preferably, described fin body leading section protrudes from and injects cover leading section.When puncturing, when medical personnel grip fin, forefinger and middle finger can clamp fin body, are more conducive to controlling puncture needle, handled easily.

Preferably, described fin body and inject between cover and be provided with lanyard.And can inject on cover and be provided with small circle ring at fin body, between small circle ring, connect lanyard, after taking off and injecting cover, injecting cover can be suspended on fin body by lanyard, is not easy to lose.

A kind of infusion needle combination type fin of the present utility model, adopts compound mode, and fin body can keep flake, and injecting cover before puncture procedure, be enclosed within fin this is external, increases its thickness, increase contact area during finger grip, and gripping surface is designed to circular arc concave surface, more meet ergonomics, make gripping more stable, puncture procedure is convenient, like this, while facilitating medical personnel to operate, also can ensure the comfort of patient, alleviate its misery.After puncture completes, will inject cover throw off, make fin body be close to skin and be fixed, and inject cover hung by lanyard, be not easy lose.
