objectiveto discuss the effect of the self-made negative pressure suction device in preoperative preparation of wound repair.methods27 patients who suffered soft tissue defect received the treatment of negative pressure suction device and underwent debridement during the time of dressing change, after 7 to 30 days （average 15.6 days） therapy, these wounds were repaired with skin grafts or flaps.resultsall of these patients' wounds became cleaner and smaller than before, and granulation tissue were fresh, the dermatoplasty or skin flap transplantation operations were successful.

目的：探讨自制简易负压吸引装置在创面修复术前期准备中的治疗作用。方法：对27例有皮肤软组织缺损的患者采用自制的简易负压吸引装置治疗，并在每次更换负压装置时进行清创。经过7～30日，平均15.6日的治疗后，在创面上行二期游离植皮或皮瓣转移修复术。结果：27例患者经过治疗后创面清洁，面积较前缩小，肉芽生长新鲜，游离植皮或皮瓣转移修复均一次性获得成功。

Then the flow coefficient could be calculated. Differential pressure was measured with varied air flow regulated by the valve. Based on the measured data, the relationship curve of the differential pressure and air flow was drawn. It could not be done in the former test platform.
