Claim:
A wound treatment apparatus applied to a wound, comprising a guiding unit, comprising: a main body having a first end and a second end, wherein the first end is communicated to the wound; an elastic member, disposed in the main body to isolate the first end from the second end, the elastic member comprising a plurality of teeth; an accommodating portion formed within the elastic member between two adjacent teeth; a negative pressure collecting module connecting with the guiding unit, comprising: a negative pressure source providing negative pressure to the wound; and a collecting device collecting exudates of the wound; wherein when the negative pressure source sucks air from the guiding unit, the elastic member deforms to allow the accommodating portion to communicate with the first end and the second end, respectively, and when the negative pressure source stops the sucking action, the elastic member is restored to allow the accommodating portion to isolate the first end from the second end.
