Abstract
The utility model belongs to the technical field of medical instruments, and aims to provide an endocrine effusion extractor. The endocrine effusion extractor aims to solve the technical problem that at present, effusion cannot completely enter a liquid storage tube in an effusion extracting process. The endocrine effusion extractor comprises a negative-pressure needle tube, and the negative-pressure needle tube comprises a needle barrel, a needle head, a piston and a pintle, wherein the needle head is arranged at the front end of the needle barrel, the piston is disposed in the needle barrel, and the pintle is connected with the piston. The endocrine effusion extractor is characterized in that the wall, which is close to the lower side of the front end, of the needle barrel outwards extends to form an effusion outlet port, a spacing block is arranged in the needle barrel, faces a position above the effusion outlet port, and extends to the inside of the effusion outlet port so as to divide the needle barrel and the effusion outlet port into front parts and rear parts, and the piston is located in the rear part of the needle barrel. The endocrine effusion extractor is reasonable in structure, is operated simply and conveniently, and can be widely applied to endocrine effusion extraction.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically is meant a kind of endocrine hydrops withdrawal device.
Background technology
The endocrine disturbance can cause the hydrops at positions such as thoracic cavity, abdominal cavity, adopts tapping to diagnose and treat clinically mostly, after drawing liquid, shifts liquid onto in vitro censorship.Adopt this mode, in the process that liquid shifts, cause the pollution of liquid easily, thereby cause the inaccurate of testing result, the influence treatment.ZL200920227239.7 endocrine disturbance hydrops withdrawal device, the disclosed withdrawal device of this patent comprises the negative pressure needle tubing, is provided with connection tube in negative pressure needle tubing underside of forward, and the inner chamber of connection tube is communicated with the negative pressure syringe intracavity, and the liquid storage test tube is enclosed within on the connection tube.This hydrops withdrawal device can be extracted into hydrops in the liquid storage pipe in drawing liquid, has saved the process that liquid shifts, and inspects the technical problem that liquid receives external contamination by ready samples thereby solved.But this withdrawal device finds in use that after the piston in the syringe leaves the connection tube mouth of pipe there have quite a few hydrops not get into liquid storage pipe to be interior but inner with being advanced into syringe behind the piston, causes the inaccurate of hydrops extraction amount.
Summary of the invention
The purpose of this utility model provides a kind of endocrine hydrops withdrawal device, to overcome the technical problem that hydrops can not get into liquid storage pipe fully in the drawing liquid process at present.
For realizing above-mentioned technical purpose; The technical scheme that this utility model adopts is: a kind of endocrine hydrops withdrawal device; Comprise the negative pressure needle tubing; The negative pressure needle tubing comprises piston that the syringe needle, syringe of syringe, syringe front end is inner and the pintle that links to each other with piston, it is characterized in that: said syringe stretches out in the downside needle cylinder wall near front end and one goes out liquid interface, is being provided with a shaping piece over against the syringe inside that goes out above the liquid interface; Shaping piece extend to out liquid interface inside with syringe and go out liquid interface be divided into before and after two parts, piston is positioned within the syringe latter half.
The beneficial effect of this utility model is: since in the syringe set inside shaping piece, hydrops can be entered in the liquid storage pipe through going out liquid interface before the shaping piece by shutoff fully, has prevented that hydrops from moving with piston and get in the syringe of back.This utility model is rational in infrastructure, easy and simple to handle, can be widely used in the extraction operation of endocrine hydrops.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
Among the figure, 1, syringe, 2, syringe needle, 3, piston, 4, pintle, 5, go out liquid interface, 6, shaping piece, 7, liquid storage pipe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Shown in accompanying drawing, a kind of endocrine hydrops withdrawal device comprises the negative pressure needle tubing, and the negative pressure needle tubing comprises piston 3 that syringe needle 2, the syringe of syringe 1, syringe front end is inner and the pintle 4 that links to each other with piston.
As shown in the figure; The difference of this utility model and conventional needle tubing is; Syringe 1 stretches out in the downside needle cylinder wall near front end and one goes out liquid interface 5; Be provided with a shaping piece 6 over against the syringe inside that goes out above the liquid interface, shaping piece 6 extend to out liquid interface 5 inside with syringe 1 and go out liquid interface 5 be divided into before and after two parts, piston 3 is positioned within the syringe latter half.
As shown in the figure, during practical application, liquid storage pipe 7 is connected on out on the liquid interface 5; Two parts before and after shaping piece 6 is divided into syringe 1 and the inside that goes out liquid interface 5; But two parts communicate through liquid storage pipe 7 again, and in the process of therefore behind pulling piston 3, moving, syringe inner chamber and liquid storage pipe 7 inside before the piston 3 all produce negative pressure; The endocrine hydrops is drawn out of, and the endocrine hydrops of extraction can only enter into liquid storage pipe 7 along the first half outlet that goes out liquid interface 5 owing to receive the obstruct of shaping piece 6.
