The invention discloses a negative-pressure drainage device. The negative-pressure drainage device comprises a drainage tube and a liquid storage bag, wherein a liquid input end of a negative-pressure drainage ball is connected with the drainage tube through a connecting tube, a liquid output end of the negative-pressure drainage ball is connected with the liquid storage bag through a second connecting tube, the liquid input end and the liquid output end of the negative-pressure drainage ball are respectively arranged at the upper end part and the lower end part thereof, an exhaust hole is formed in the upper end part of the negative-pressure drainage ball, a first one-way valve which communicates from the outside to the inside is installed in the liquid input end, a second one-way valve which communicates from the inside to the outside is installed in the exhaust hole, and a control valve is installed on the second connecting tube. In this structure, after the negative-pressure drainage ball is contracted to exhaust air from the second one-way valve, the drainage tube is placed in a chamber to be drained; when the negative-pressure drainage ball is expanded, body liquid can be drained into the negative-pressure drainage ball, and thus the operation is simplified and the device is more convenient to use.
Description
technical field [0001] The invention relates to a medical device, in particular to a negative pressure drainage device. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in recent years for the treatment of wounds. It uses bio-semipermeable membranes to seal open wounds, generates a certain negative pressure through negative pressure drainage devices, and acts on the wound surface through drainage tubes and dressings. The wound after debridement can accelerate the blood circulation of the wound, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, inhibit the growth of bacteria, and directly accelerate wound healing, or for surgical repair creating condition. The existing negative pressure drainage device comprises a negative pressure drainage ball, the input end of the negative pressure drainage ball is connected wi...
