Abstract
The utility model discloses a thoracocentesis device which comprises an injection needle barrel (1), a puncture needle (2), a piston (3), a piston rod (4), a handle (5) and a sucking-in catheter (6). The puncture needle (2) is connected with the injection needle barrel (1) through the sucking-in catheter (6), the piston (3) is arranged in the injection needle barrel (1), the piston rod (4) is fixed at the rear end of the piston (3), the handle (5) is fixed at the other end of the piston rod (4), a latex tube (7) communicated with an inner cavity of the injection needle barrel (1) is arranged on the lower side wall of the injection needle barrel (1), the tail end of the latex tube (7) is connected with a measuring flask (8), and the sucking-in catheter (6) is provided with a flow switch (10) and a three-way switch (9). The thoracocentesis device is simple in structure, capable of sucking pleural effusion of any amount by one time of puncture according to needs, capable of injecting medicine in the effusion sucking process, and convenient to operate and use, and complex puncture processes are reduced.
Description
Technical field
The utility model relates to the medical instrument field, be specifically related to a kind of thoracic puncture set.
Background technology
thoracic puncture set is the medical apparatus and instruments of often using in cardiac thoracic surgery, it is by thrusting torso model with puncture needle, then utilize the negative pressure in syringe successfully the hydrops in torso model or gas to be extracted out, in the diseases such as treatment pneumothorax or pleural effusion, good effect is arranged, but there is a problem in this common perforator: when the hydrops in human body or gas when less, utilizing this perforator to extract once can complete, but when the hydrops that need extract or gas are more, necessary repeated multiple times extraction, puncture needle must be pulled out each time, pour out liquid in syringe, then extract next time, so operation is very loaded down with trivial details, not only increased patient's misery, also increased the weight of medical personnel's working strength.
The utility model content
For the existing deficiency that exists, this utility model purpose is to be to provide a kind of thoracic puncture set.
to achieve these goals, this utility model is to realize by the following technical solutions a kind of thoracic puncture set, comprise syringe cylinder, puncture needle, piston, piston rod, handle and suction catheter, described puncture needle is connected with syringe cylinder by suction catheter, be provided with piston in syringe cylinder, piston rear end is fixed with piston rod, the piston rod other end is fixed with the hands handle, the lower wall of syringe cylinder is provided with the latex tubing that is communicated with the syringe inner chamber, latex tubing end connection capacity bottle, described suction catheter is provided with flow switch and three-way cock, described three-way cock is provided with the injection interface.
As preferably, described puncture needle is provided with graduation mark, and clear and definite puncture needle thrusts the degree of depth.
As preferably, described puncture needle rear end is fixed with the sucker of adsorbable human body skin.
A kind of thoracic puncture set of the present utility model is simple in structure, can accomplish that one-time puncture just can extract the hydrothorax of any amount as required, can be in the time of drawing liquid and injection of medicine, and easy for operation, reduced the puncture complicated processes.
