The drainage tube comprises an inlet section and an outlet section, the inlet section is arranged in polyvinyl alcohol sponge, the tube wall of the inlet section is provided with at least one drainage hole, the outlet section is arranged outside the polyvinyl alcohol sponge and is provided with an external connection port, a plug is arranged in the external connection port, the end of the outlet section is connected with a container, and the container is connected with a negative pressure source. The negative-pressure drainage device is suitable for surgical drainage.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a negative pressure drainage device for surgical drainage. Background technique [0002] When the patient is subjected to various acute traumas, skin and soft tissue injuries, and ulcers and bedsores caused by various reasons, the patient's skin will have exudate, and the exudate must be removed at this time so that the wound can heal faster. At present, the wiping with medical cotton wool is mostly used to remove the exudate. However, when using medical cotton to wipe the wound, if the wiping force is too large, the wound is likely to suffer secondary trauma; and the medical cotton is prone to fiber shedding, and the fibers falling into the wound will cause damage to the wound; Limited, when there is a lot of exudate at the wound, a large amount of medical cotton must be used, which not only causes a lot of waste but also pollutes the environment. Contents of the invention ...
