Abstract
An automatically flat clamp medical injection needle of the utility model comprises a pintle, a needle stem and a needle point. The utility model is characterized in that the side wall of the pintle is opened with small air-inlet openings and a layer of film-separating net is added inside the small air-inlet openings. In the process of the flooding of an injector, the utility model is capable of taking-in air simultaneously, then the formation of the negative pressure inside a bottle is avoided, thereby the repeated de-needling to suck air can be avoided, the working efficiency is increased, the pollution is reduced, the infusion reaction is prevented, enough medicine fluid which enters the human body is ensured, and the therapeutic effect is increased.
Description
Technical field
This utility model relates to a kind of syringe needle.
Background technology
Injection needle is made up of pintle, pin stalk, needle point, cooperates with the nipple end of syringe piston tube.Need be at clinical transfusion toward the air of injection in infusion bottle or the medicine bottle, to increase pressure of the inside of a bottle or to equate with external atmosphere pressure with required medicinal liquid equivalent.In case the formation negative pressure is transferred to syringe needle to inhale the equivalent air once more and is injected in bottle, to have aspirated repeatedly since like this, nurse's power of giving up is lost time, and is easily polluted, and causes infusion reaction, and micro-medicated fluid loss is arranged, and causes the amount of liquid medicine deficiency, influences therapeutic effect.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automatic concora crush syringe needle, and air inlet simultaneously in the fluid injection process avoids a bottle interior negative pressure to form.
The automatic concora crush syringe needle of this utility model comprises pintle, pin stalk, needle point, it is characterized in that having the air inlet aperture on the pintle sidewall, is added with one deck barrier film net in the air inlet aperture.
Air inlet aperture on the pintle sidewall can guarantee that air inlet gets final product, and the aperture of barrier film net is the smaller the better, gets final product not hinder air inlet and leakage.During actual the use, when the piston push rod of syringe promoted medicinal liquid by the needle injection medicinal liquid, medicinal liquid penetrated with rectilinear direction, and is just very little by the probability of sidewall aperture leakage itself, so the setting of air inlet aperture can not have influence on the normal use of syringe, still more the air inlet aperture open very little.
Front end after pintle both can corresponding nipple end at the syringe piston tube be inserted in the position of air inlet aperture also can be corresponding to the nipple end of piston cylinder and the cooperation position of pintle.
Advantage of the present utility model:
Air inlet simultaneously in syringe fluid injection process is avoided a bottle interior negative pressure to form, thereby has also been avoided pulling out the pin suction air repeatedly, has improved work efficiency, has reduced opportunities for contamination, has avoided infusion reaction, can guarantee that enough medicinal liquids enter human body, improves therapeutic effect.
