The specific embodiment
For shape of the present invention, structure and feature can be understood better, below will enumerate preferred embodiment and be elaborated by reference to the accompanying drawings.
In per rectum, three-cavity air bag closed drainage pipe box dress mainly comprises two parts: three-cavity air bag closed drainage pipe and external fixing device in per rectum.In per rectum, three-cavity air bag closed drainage pipe comprises main drainage tube 2, on the outer wall of main drainage tube 2 front ends, is bonded with air bag 1, and the inner termination of main drainage tube 2 exposes to air bag 1 front end, in order to drain feces.The external end head of main drainage tube 2 is provided with main drainage tube cap 6, in order to the external end head of opening and closing of fault main drainage tube 2.
Secondary drainage tube 5 is located on main drainage tube 2, and the inner termination of secondary drainage tube 5 is positioned at air bag rear end.Have a gas tube 4 to reach in air bag 1, there is charging valve 3 gas tube 4 rear ends.During use, the external end head of main drainage tube 2 is connected with general drainage bag, and the external end head of secondary drainage tube 3 is connected with vacuum extractor, to keep wound surface portion enteric cavity to be beneficial to the healing of wound surface in closure and clean conditions.
