Abstract

The utility model discloses a pleural effusion and ascites drawing liquid device, which comprises a needle, wherein the needle is connected with a liquid inlet port of a three-way pipe through a pipeline, a liquid drainage port of the three-way pipe is connected with a liquid receiving device through the pipeline, another one branch port of the three-way pipe is connected with an injector through the pipeline, the pipeline in the inner portion of the three-way pipe is respectively equipped with two plug elastic switches which are used to control liquid to enter and drainage, channels are sealed by the plug elastic switches in a static state, the plug elastic switch on a liquid inlet port channel is automatically opened when pumping liquid, the plug elastic switch on a liquid drainage port channel is located in a sealing state and vice versa when drainaging the liquid, thereby controlling the whole process of pumping and drainaging the liquid at an unidirectional direction, and achieving the automatic control of pumping the liquid in thoracic and abdominal cavities. The structure is simple, and the use is convenient.

Description

The ascites pleural fluid liquid extracting device

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially designs a kind of breast, seroperitoneum withdrawing device.

Background technology

When treating some disease on the hospital clinical, sometimes need endoceliac hydrops is extracted out, especially to breast, Intraabdominal hydrops is extracted out, when hydrops more for a long time, need carry out continuous drawing liquid, the continuous liquid extracting device of the ascites pleural fluid of prior art (patent No. ZL99223735.1), be between syringe needle and syringe, to add check valve, when drawing liquid, a check valve is opened another closed check valve, and the check valve of liquid through opening injected in the syringe tube, during the discharge opeing body, the check valve switch is reverse, and the pushing syringe nook closing member is discharged liquid in the syringe shop from the check valve of opening.This liquid extracting device need ceaselessly repeat to open, close the operation of check valve, medical worker's complex operation.

The utility model content

Technical problem to be solved in the utility model provides a kind of ascites pleural fluid liquid extracting device simple in structure, easy to use.

For solving the problems of the technologies described above, the technical solution of the utility model is: the ascites pleural fluid liquid extracting device, comprise syringe needle, described syringe needle is connecting the inlet of tee T by pipeline, the leakage fluid dram of described tee T connects the liquid receiving system by pipeline, another mouth of described tee T connects syringe by pipeline, be separately installed with the plug elastic switch that plug and spring constitute on the inlet of described tee T and the leakage fluid dram pipeline, and the plug in the inlet passage in the plug elastic switch is pressed close to inlet, and the plug in the leakage fluid dram passage in the plug elastic switch is away from leakage fluid dram.

As a kind of preferred version, described liquid receiving system can be drainage bag or disposable urine drainage bag.

As a kind of preferred version, conical structure is adopted in the coupling of described inlet and leakage fluid dram.

As to improvement of the technical scheme, described inlet and leakage fluid dram coupling are provided with anti-slip tank.

Owing to adopted technique scheme, the ascites pleural fluid liquid extracting device, comprise syringe needle, described syringe needle is connecting the inlet of tee T by pipeline, the leakage fluid dram of described tee T connects the liquid receiving system by pipeline, another mouth of described tee T connects syringe by pipeline, be separately installed with the plug elastic switch that plug and spring constitute on the inlet of described tee T and the leakage fluid dram pipeline, and the plug in the inlet passage in the plug elastic switch is pressed close to inlet, and the plug in the leakage fluid dram passage in the plug elastic switch is away from leakage fluid dram.Two plug elastic switch are set respectively on the tee T internal pipeline are used to control feed liquor and discharge opeing, plug elastic switch closed channel in static state, inlet passage upper plug head elastic switch is opened automatically during drawing liquid, leakage fluid dram passage upper plug head elastic switch still is in closed state, otherwise during discharge opeing, thereby finished the overall process of unidirectional control drawing liquid discharge opeing, realized the automatic control of splanchnocoel drawing liquid, easy to use, and simple in structure.
