Description
技术领域technical field
本实用新型属于医疗技术领域，具体涉及一种皮下积液综合治疗装置。The utility model belongs to the field of medical technology, in particular to a comprehensive treatment device for subcutaneous effusion.
背景技术Background technique
外科手术后，病人由于肥胖、营养状况较差、高血糖及手术切口感染等原因容易出现皮下脂肪液化，进而导致皮下有大量的积液影响伤口的愈合，此时需要将手术切口下方的液体引流出来，进而促进伤口愈合，现有方案需要用注射器抽吸生理盐水润湿纱布之后，将纱布剪成与手术切口相适应的形状，然后将纱条塞入切口内，所以操作过程较为麻烦，而且浪费一瓶生理盐水及注射器。效果较差，现有方案通过纱条的吸引作用促进伤口内的液体排出，而纱条的吸引力很差，所以不能将伤口内的液体完全吸引出来，而且纱条只能吸引液体，不能将坏死的物质吸引出来，所以伤口可能继续感染或脂肪液化。对于伤口较长的病人，塞入纱条的长度有限，用镊子塞入纱条较为困难，不易塞入最低端。塞纱条需要每天将原有纱条掏出并放置新的纱条，浪费时间并增加伤口感染风险。对于伤口愈合较快的病人，伤口内的肉芽组织容易长入纱布内，此时拉出纱布时容易疼痛并出血。After surgery, patients are prone to liquefaction of subcutaneous fat due to obesity, poor nutritional status, hyperglycemia and surgical incision infection, which in turn leads to a large amount of subcutaneous fluid that affects wound healing. At this time, the fluid under the surgical incision needs to be drained. out, and then promote wound healing, the existing scheme needs to use a syringe to aspirate the physiological saline to wet the gauze, cut the gauze into a shape suitable for the surgical incision, and then insert the gauze into the incision, so the operation process is more troublesome, and Waste a bottle of saline and a syringe. The effect is poor, and the existing solution promotes the discharge of the liquid in the wound through the attraction of the gauze, but the attraction of the gauze is very poor, so the liquid in the wound cannot be completely sucked out, and the gauze can only attract the liquid, not the Necrotic material is drawn out, so the wound may continue to become infected or the fat liquefies. For patients with long wounds, the length of the inserted gauze is limited, and it is difficult to insert the gauze with tweezers, and it is not easy to insert the lowest end. Tucked sliver requires daily removal of the old sliver and placement of a new sliver, wasting time and increasing the risk of wound infection. For patients with fast wound healing, the granulation tissue in the wound is easy to grow into the gauze, and it is easy to cause pain and bleeding when pulling out the gauze.
