Negative-pressure wound therapy (NPWT) has become the standard of care for wound management. Application of NPWT to the hand and foot is technically challenging due to difficulty in obtaining a proper air seal. The cost of the treatment is another negative factor affecting NPWT in developing countries. We describe an easy and economical technique for the application of NPWT to the extremities using collage powder and sterile surgical glove. Collagen creates a physiological interface between the wound surface and the environment and is also non-immunogenic, non-pyrogenic, hypoallergenic, and pain-free. We used this method in 20 patients. In all cases, we could achieve a proper air seal and significantly reduce the cost. The median duration of NPWT application was 9 days. This combination turned out to be a good alternative to traditional VAC with respect to the duration and cost of treatment and also ergonomically better in the management of extremity wounds.
负压伤口治疗（NPWT）已成为伤口管理的护理标准。由于难以获得合适的气密效果，将NPWT应用于手和足部在技术上具有挑战性。治疗成本是影响发展中国家NPWT应用的另一个负面因素。我们描述了一种使用胶原蛋白粉和无菌手术手套将NPWT应用于四肢的简便且经济的技术。胶原蛋白在伤口表面与环境之间形成生理界面，并且还具有非免疫原性、无热原性、低过敏性且无痛的特点。我们对20例患者使用了这种方法。在所有病例中，我们都能实现合适的气密效果并显著降低成本。NPWT应用的中位持续时间为9天。就治疗持续时间和成本而言，这种组合被证明是传统VAC的良好替代方案，并且在四肢伤口管理方面在人体工程学上也更优。
