A negative pressure wound therapy system capable of detecting exudate color, comprising: a liquid collecting bottle (5) for collecting wound exudate; a negative pressure wound therapy device (8), comprising a negative pressure source (6) and a controller (7); a wound kit, for being filled in a wound and sealing the wound, and communicated with the liquid collecting bottle (5) by a connecting pipe (4); a color collecting system (9), for acquiring a color signal and/or visual signal of the exudate; and a color detection and control unit, provided in the controller (7), and used for calculating the color corresponding to the exudate according to the acquired color signal and/or visual signal of the exudate. Through on-line detection of the exudate color, the negative pressure wound therapy system generates an alarm signal in time to alert medical care personnel or patients to take measures in time before accidents, and the medical care personnel also can perform more advanced study on wound information conveniently. |
