Abstract
The utility model provides a thoracocentesis device operated by one person. The thoracocentesis device comprises a puncture needle. The tail portion of the puncture needle is communicated with a negative-pressure suction bottle through a first drainage tube. The negative-pressure suction bottle is communicated with a drainage bag through a second drainage tube. The first drainage tube is provided with a first one-way valve. The second drainage tube is provided with a second one-way valve. When the negative-pressure suction bottle expands, the first one-way valve is opened, and the second one-way valve is closed; when the negative-pressure suction bottle contracts, the first one-way valve is closed, and the second one-way valve is opened. Before puncture, firstly, the person treads the negative-pressure suction bottle, inserts the puncture needle and releases the foot at the same time, and pleural effusion will flow into the negative-pressure suction bottle through the first drainage tube; then, the person treads the negative-pressure suction bottle so that the pleural effusion in the negative-pressure suction bottle can be drained into the drainage bag through the second derange tube. In this way, the pleural effusion can be easily and conveniently pumped by one person, and therefore labor cost is lowered; furthermore, the puncture needle can pump out the pleural effusion immediately under the action of negative pressure after being inserted into the thoracic cavity, and the pleural effusion pumping speed can be controlled by treading the negative-pressure suction bottle.
