摘要：
A negative pressure drainage and cleaning system for sutureless closure of a skin wound. The system comprises: a flushing device (1), which comprises a conveying pump (103) and a first catheter (105) partially probing into a subcutaneous wound internal cavity (8) at a preset depth and is used for conveying a cleaning solution by means of the first catheter (105) to the preset depth of the subcutaneous wound internal cavity (8)； a negative pressure device (2), which comprises a negative pressure source (202) and a second catheter (205) partially probing into the subcutaneous wound internal cavity (8) at a preset depth and is used for generating negative pressure to force the subcutaneous wound internal cavity (8) to be closed during healing and draining effusion in the subcutaneous wound internal cavity (8) by means of the second catheter (205)； a control device (3), electrically connected to the flushing device (1) and the negative pressure device (2) and used for maintaining a vacuum degree of the subcutaneous wound internal cavity (8) by controlling the output pressure or flow of the flushing device (1) and the negative pressure device (2) according to the received feedback.The system can assist to implement the sutureless closure of a full-thickness tissue above the deep fascia of the skin, avoids horizontal scars on the skin surface caused by suture compression/cutting, and leaves no suture knots in the superficial fascia, thereby eliminating an important factor which causes colonization of bacteria and a main cause of recurrence of wound infection.L'invention concerne un système de drainage et de nettoyage à pression négative pour la fermeture sans suture d'une plaie cutanée. Le système comprend : un dispositif de rinçage (1), qui comprend une pompe de transport (103) et un premier cathéter (105) pénétrant partiellement dans une cavité interne (8) de plaie sous-cutanée à une profondeur prédéfinie et servant à transporter une solution de nettoyage au moyen du pr
