Cast Liner for Early Detection and Prevention of Skin Infections

Abstract

The orthopedic cast immobilization is popular when dealing with the fracture and the fact that it is surrounded by the entire cast does not allow one to observe the condition of the skin at all times. When an individual is immobilized for a long period of time, the moisture level, temperature, humidity and skin pH can change and this can cause maceration of the skin, irritation, infection and patient discomfort. These complications are, in most instances, only revealed after the symptoms have become apparent, and this reflects the necessity of a preventive method of monitoring. This paper gives the design and development of a smart wearable cast liner that is aimed at monitoring the microenvironment under the orthopedic casts. The proposed system will combine the moisture, body temperature, environmental temperature and humidity sensors, and the skin pH. Microcontroller, which has the ability of wireless communication, is used to process sensor data to facilitate real-time monitoring and issue alerts in the event of abnormal conditions detected. Besides that, the coin vibration motors are also integrated to offer the patient controlled noninvasive itch relief. To show that the system is feasible, a working prototype of the system has been created. The proposed device will help patients and caregivers to detect unfavorable conditions at an early stage when they are immobilized. It will be possible to evaluate the system clinically in the future to find out how effective it is in the actual healthcare environment.
