Design and Application of Wearable Combined Wound Healing Devices

Purpose: to design a kind of device with which wound patients are able to receive treatment at home in a long-term, safe and reliable manner.

The highlight is that different parts after dismantled can play an important role in clinical operation.

Methods: The said device is designed using several sensors. It consists of four parts: 1. repeatable negative pressure device, which can be adjusted automatically in the case of air leakage; 2. body fluid management system around the wound; 3. wound effusion management system; 4. tube removal resistant and anti-shift alarm system. 56 patients are chosen, and they are divided randomly into 30 patients using wearable negative devices (test group) and 26 patients using traditional negative pressure devices (control group). The frequency of changing the dressing, healing time, occurrence of peripheral skin complications, tube removal rates and air leakage rates of the two groups of patients are compared.

Result: There is difference (P<0.05) between the test group and the control group in healing time. And for other indices, the test group is far superior to the control group (p<0.01).

Conclusion: Medical treatment of patients’ wounds using the wearable negative pressure devices can increase healing speed, reduce the frequency of changing the dressing, decrease the occurrence of peripheral wounded skin complications, reduce tube removal, save medical treatment costs and minimize the labor of medical staff.
