Problems solved by technology

prone to counting errors due to sometimes memory errors, sometimes mixed with foam
The size of the suction negative pressure is completely adjusted by the operator through the control of the syringe. The pressure is unstable. If the negative pressure is too small, the suction may not be possible. Sliding lung causing injury
Vibration of the needle due to suction action can also lead to accidental injury to internal thoracic organs

Abstract

The invention provides an automatic thoracentesis suction device which comprises a puncture needle. The automatic thoracentesis suction device is characterized in that a liquid-column pressure suction device is connected onto the puncture needle, is arranged vertically and is lower than the puncture needle. The automatic thoracentesis suction device has the advantages that the automatic thoracentesis suction device can be operated easily and conveniently and is convenient and sanitary, labor is saved, fatigue of operators is prevented owing to the fact that hydrops are automatically sucked under the negative pressure, the hydrops can be prevented from being contaminated, environments can be prevented from being polluted by the hydrops, and patients are prevented from being accidentally injured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic chest puncture suction device for preventing pollution. Background technique [0002] At present, when the fluid is extracted during the operation, two people are required to cooperate. A thoracentesis was performed by one person, and the pleural effusion was aspirated through an interpreter. After filling the syringe with fluid, the syringe needs to be separated from the drainage tube to remove the fluid. In order to prevent open pneumothorax caused by venting the chest cavity, or fluid outflow, another person needs to clamp the drainage tube connected to the puncture needle through a hemostat. After the syringe is emptied, the drainage tube is connected again, and the other person releases the hemostat, draws the fluid again, and so on. [0003] This method is cumbersome to operate and requires two people to work together, and the work efficiency is low; ...
