Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of for liquid suction pipe syringe needle, belongs to medical drawing liquid, blood drawing instrument.
Background technology
Syringe needle is the most frequently used the loaded and unloaded parts of domestic and international syringe, and existing syringe needle is a kind of metal needle and dispensing needle head, and syringe needle generally comprises the metal tube and the headgear for being connected with syringe with needle point.
At present, syringe needle is while for syringe, directly can also be enclosed within the front end of tube for transfusion, reach and transfusion and drawing liquid function, hospital is general syringe needle and the combined form of liquid suction pipe in drawing liquid medical procedure, liquid suction pipe adopts flow speed controller, the speed of flow speed controller scalable drawing liquid and keying, although but adopt this flow speed controller to reach the effect of adjustment, but the drawing liquid process of single can only be carried out, at the end of drawing liquid, need to carry out keying by flow speed controller to control, and when drawing liquid, the actual volume of drawing liquid cannot be estimated, easily there is the problem that drawing liquid is too much.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid suction pipe syringe needle, by adopting negative pressure drawing liquid and syringe needle to arrange micro-control device in drawing liquid process, solving traditional liquid extracting device and cannot connect the problem that drawing liquid and liquid cannot estimate.
The technical scheme in the invention for solving the technical problem is such:
A kind of liquid suction pipe syringe needle, comprise a tubulose syringe needle and the thin wall casing being sleeved on end of tubular needle head-tail, the first end of end of tubular needle is most advanced and sophisticated, the other end and thin wall casing grafting, its key technology is, the motion stops that described tubulose syringe needle is built-in with valve plate and is connected with valve plate, described valve plate outward flange is connected with tubulose syringe needle inner wall sealing, valve plate central part offers through hole, described motion stops is by non-return cock cap, connecting rod, back-moving spring, limit base and control line are formed, non-return cock cap is connected with limit base by connecting rod, limit base is connected with control line, back-moving spring is sleeved on connecting rod, back-moving spring two ends respectively with limit base and valve plate apical grafting, described thin wall casing end is provided with double tube adapter sleeve, and one end of double tube connection tube is communicated with thin wall casing, and the other end is communicated with side pipe one end with supervisor respectively, and the described side pipe other end is communicated with volumetric flask, and volumetric flask is circumscribed with negative tube.
Further improvement of the utility model is: described tubulose syringe needle is made up of needle point and needle tubing, and needle point and needle tubing are socketed.
The beneficial effects of the utility model are:
Liquid suction pipe syringe needle in this utility model adopts built-in micro-amounts of liquids controller, instead of traditional external flow speed controller, built-in flow speed controller is owing to adopting the structure of valve plate and motion stops, not only can realize the effect of coutroi velocity, and reach the effect opened and closed at any time, achieve in drawing liquid process without the need to pulling out pin and continuous drawing liquid; Have at the thin wall casing end peripheral hardware coordinated with liquid suction pipe syringe needle and negative pressure drawing liquid is provided and the volumetric flask that drawing liquid volume estimates can be realized, not only achieve negative pressure drawing liquid but also can real-time monitored drawing liquid volume, avoid drawing liquid to cross the secondary injury of multipair patient.
