A wound treatment apparatus and exudate guiding unit thereof. The wound treatment apparatus connecting to a wound includes the guiding unit and a negative pressure collecting module. The guiding unit includes a main body, an elastic member and an accommodating portion. The main body has a first end and a second end, wherein the first end is communicate with the wound. The elastic member is disposed in the main body to isolate the first end and the second end. The accommodating portion is formed within the elastic member. The negative pressure collecting module connects with the guiding unit, includes a negative pressure source and a collecting unit, and connects with the second end. When the negative pressure source provides a negative, the elastic member is deformed to allow the accommodating portion to communicate with the first end and the second end. When the negative pressure source stops operating, the elastic member returns to its original shape to isolate the accommodating portion, the first end and the second end.一種創傷處理裝置及其導液單元。創傷處理裝置連接於傷口,包括導液單元以及負壓集液模組。導液單元包括主體、彈性件以及容納部,主體具有第一端以及第二端,其中第一端與傷口連通;彈性件設置於主體中,將第一端與第二端隔離;容納部形成於彈性件內部。負壓集液模組係與導液單元連接,其包括一負壓源與一集液裝置。負壓集液模組與第二端連通。當負壓源提供負壓時,彈性件變形使容納部分別與第一端與第二端連通,當負壓源停止時,彈性件回復原狀使容納部分別與第一端與第二端隔離。10‧‧‧創傷處理裝置110‧‧‧導液單元1101‧‧‧第一端1102‧‧‧第二端111‧‧‧主體113‧‧‧彈性件115‧‧‧容納部130‧‧‧連接單元150‧‧‧負壓源170‧‧‧集液裝置190‧‧‧壓力感測器R‧‧‧流阻結構T‧‧‧齒部T1‧‧‧第一管路T2‧‧‧第二管路TS‧‧‧不透氣表層W‧‧‧傷口
