The purpose of this utility model, be to avoid weak point of the prior art, and provide a kind of thoracic cavity gas-liquid to attract drainage device continuously, it can carry when breathing with the thoracic cavity formed pressure differential in order to open two check valves by patient, attract hydrothorax or pneumatosis, and initiatively drain, can execute external force extruding leather bag again, utilize the hydrops or the pneumatosis in the vacuum suction thoracic cavity that forms in the leather bag, and installed drainage bottle, in order to the pressure differential and the volume of metering of measuring patient respiration, can avoid the pollution of chest fluid again by the thoracic cavity drain.

The purpose of this utility model can reach by following measure: the thoracic cavity gas-liquid of a kind of attraction and drain torso model hydrops and gas attracts drainage device continuously, include leather bag 1,

check valve

2,3,

drainage tube

6,7,8, drainage bottle 9, insert graduated glass tubing 10 in the drainage bottle, form by leading to atmospheric glass tubing 11 and drain bottle stopper 12 etc. in the drainage bottle.The switching resistance that it is characterized in that

check valve

2,3 is equal to or less than 2 millimeters of water, and can rely on formed pressure differential

switching check valve

2,3 when breathing and initiatively drain.Or push leather bag 1 by external force and utilize the Negative Pressure Difference that forms in the leather bag to open and

close check valve

2,3 and passive drain.

The purpose of this utility model can also reach by following measure: the check valve of installing on the drainage tube that connects thoracic cavity one end 2, its flow direction is led to leather bag 1, the check valve of installing on the drainage tube that connects drainage bottle one end 3, its flow direction is led to drainage bottle 9.Leather bag 1 is with elastic material manufacturings such as rubber or

plastics.Check valve

2 and 3 valve body are that valve block the 4, the 5th is with other elastomeric material manufacturings such as silica gel with light plastic or lucite manufacturing.

This utility model has following accompanying drawing:
