本文通过时１４４例乳癌患者术后采用一次性负压引流器、胃肠减压吸引器、低负压电动吸引器三种方法行创口负压引流，对术后皮下积液发生率进行对比观察，结果证明，一次性负压引流器容量小、引流过程中压弹簧易自动松开，负压随之消失；胃肠减压器也不能持续维持有效负压，二者对皮下渗血、渗液均不能及时引出。低负压电动吸引器可根据需要调节负压吸引力，能持续稳定地保持所需负压，使皮肤紧贴皮下组织，皮下积液发生率明显低于前两者。
This article through 144 cases of breast cancer patients after a negative pressure drainage device, gastrointestinal decompression suction device, low negative pressure electric suction device wound wound drainage three methods, the incidence of subcutaneous fluid after the comparison observed The results show that the capacity of disposable negative pressure drainage device is small, the pressure spring is easy to loosen and the negative pressure disappears during the drainage process; the gastrointestinal regulator can not continue to maintain effective negative pressure, both of them subcutaneously oozing and seeping Liquid can not lead out in time. The low suction electric aspirator can adjust the negative pressure attraction according to need, can maintain the required negative pressure continuously and stably, make the skin close to the subcutaneous tissue, the incidence of subcutaneous effusion is significantly lower than the first two.
