Abstract
Disclosed is a thoracic and abdominal cavity puncture and drainage device, which comprises a liquid-storing bag, a puncture needle, an injector and a guide pipe. The thoracic and abdominal cavity puncture and drainage device is characterized in that the puncture needle is connected with the front end of the guide pipe, the injector is connected with the tail end of the guide pipe, a three way cock is arranged on the guide pipe, a guide branch pipe is connected with a three way cock, and the liquid-storing bag is connected with the guide branch pipe, a first one-way valve is arranged on the guide pipe between the three way cock and the puncture needle, and a second one-way valve is arranged on the guide branch pipe. When using, the injector is pumped, liquid enters the injector after passing through the guide pipe, the first one-way valve and the three way cock, when the liquid in the injector is full, the injector is pushed, and then, the liquid enters the liquid-storing bag after passing through the guide pipe, the three way cock and the second one-way valve, and the liquid is collected and drained reciprocally like this. Because the first one-way valve and the second one-way valve are all one-way valves, the liquid can not return when pushing the injector. The thoracic and abdominal cavity puncture and drainage device is simple and reasonable in structure, relatively low in volume requirement to the injector, light and convenient in operation and strong in safety.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of splanchnocoel puncturing drainer.
Background technology
Publication number is that CN2535050, the patent No. are that 01280010.4 Chinese patent discloses that a kind of valve formula is taken out, drain pump, it fixes a porous type (or " rice " font) support in the syringe interior forward end, the support front places one can forward and backward mobile free diaphragm, conduit of traveling in the core bar, rear end of conduit connects a check valve, porous type support (or " rice " font) is arranged in the valve, a cell-free membrane patch is arranged before the support.Its defective is: the conduit on the liquid storing bag is connected on the core bar of syringe, and conduit is drawn by hands by core bar, when the push-and-pull core bar, can cause operation inconvenience, because liquid storing bag is connected on the conduit of syringe core rod, makes syringe can not exchange use.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of simple and reasonable, portable splanchnocoel puncturing drainer of operation is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.This utility model is a kind of splanchnocoel puncturing drainer, comprises liquid storing bag, puncture needle, syringe and conduit, is characterized in, described puncture needle is connected the front end of conduit, and syringe is connected the end of conduit; Be provided with the three way cock on conduit, be connected with a conduit on the three way cock, liquid storing bag is connected on the conduit; On the conduit between three way cock and the puncture needle, be provided with first check valve, on a conduit, be provided with second check valve.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of splanchnocoel puncturing drainer is characterized in, between described puncture needle and the conduit, be connected by female Luer between syringe and the conduit.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of splanchnocoel puncturing drainer is characterized in, is provided with tongs on puncture needle.
When this utility model uses, twitch syringe, hydrops enters in the syringe behind conduit, first check valve, three way cock; After hydrops in the syringe is taken out completely, pushing syringe, hydrops enters liquid storing bag behind main pipe, three way cock, second check valve, carry out the hydrops drain and so forth.Because first check valve and second check valve are check valve, so hydrops can not backflow during pushing syringe.Compared with prior art, this utility model is simple and reasonable, and is less to the volume requirement of syringe, operate light, high safety.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
