Description
Technical field
The invention belongs to disposable use medical apparatus and instruments, relate in particular to a kind of band and automatically get rid of the inner air tube function, can not close actuator after in pipe, filling with medicinal liquid can seal the not disposable infusion set of flow liquid automatically.
Background technology
The disposable infusion set of domestic each clinical use of clinical unit of medical institutions; Mainly form by bottle plug puncture unit protective sleeve, bottle plug puncture unit, air filter, infusion tube, dropper, dropping funnel, flow regulator, liquid medicine filter and venoclysis needle; The tradition method for using is: have before the patient not being carried out venipuncture, need to get rid of the transfusion inner air tube.It has two kinds of manual methods usually: the one, bottle plug puncture unit is inserted the transfusion bottle stopper of reversal of the natural order of things after, make dropper get rid of air in the dropping funnel up at lower liquid outlet, treat to charge in the dropping funnel dropping funnel and make it vertically can avoid producing great amount of bubbles after half; Another method is that flow regulator cuts out, pinch press dropping funnel to make it suck about 1/2 to 2/3 place of medicinal liquid to dropping funnel after, slowly open flow regulator, also can avoid producing great amount of bubbles.Also be with self-bleeding transfusion device in the market; But these a lot of times that all will exhaust medical personnel wait for that before sick bed filling with medicinal liquid in the pipe gets rid of inner air tube; Improper as when operating, having slightly; Medical personnel's a certain amount of medicinal liquid of then will releasing removes to get rid of bubble, brings inconvenience to medical personnel like this.
Summary of the invention
The object of the present invention is to provide the full self-venting transfusion device of a kind of disposable use, solve existing transfusion device and can not fill with the technical problem that medicinal liquid is got rid of the time of inner air tube in the pipe with needing before sick bed, to wait for by automatic vent.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of disposable use full-automatic exhaust transfusion device; Comprise bottle plug puncture unit protective sleeve, puncture device, air filtration film, air lock, top hose, dropper, latex medicated cap, dropping funnel, automatic exhauster, bottom hose, flow regulator, liquid medicine filter and venoclysis needle; The bottle plug puncture unit protective sleeve is placed on the puncture device; Puncture device, top hose, dropper, dropping funnel, automatic exhauster, bottom hose, liquid medicine filter connect successively, and the latex cap sleeve is connected on the dosing mouth of dropper, and flow regulator is placed on the bottom hose; The needle stand of venoclysis needle is socketed on the conehead of liquid medicine filter; Venoclysis needle is made up of catheter block, small hose, needle handle, needle tubing, needle shield and baffling device, it is characterized in that: the needle shield head end of venoclysis needle is provided with a baffling device, and baffling device is made up of exhaust seat, air filtration film and Nei Sai; The air filtration film is embedded in through interior plug in the head end of exhaust seat, and the air filtration film is the film that blocks water.
The above-mentioned full exhaust transfusion device of disposable use, the exhaust seat of said baffling device can be an one with the transfusion needle needle shield, and is also separable.
The above-mentioned full exhaust transfusion device of disposable use, the exhaust seat axial centre place of said baffling device can establish a tiny passage, and there is the step that engages with the air filtration film at the passage rear portion.
