Abstract
Pressure ulcers cause a lot of pain and discomfort in the patient. It also has a negative impact on the quality of life. Some patient’s treatment process may be take longer in hospitals. Like accident injuries, orthopedic treatments, long-term oncologic treatments. In these processes the time that spent on patient beds is very important. These patients must not be moved while the healing process. Especially elderly patients’ and in these long-term patients some bed injuries may occur because of the pressure on their body named bed sores. Due to the negative effects of pressure ulcers on patients and costly treatment, they must be prevented. Controlling the pressure intensity can help prevent pressure ulcers. Currently, the solutions to prevent pressure ulcers include using different methods for movement and displacement of patients. In this study, a patient bed has been designed to prevent pressure ulcers in long-term inpatients as application of electronics in medicine. In this bed, several plastic balls placed on pressure points. These points are the most pressurized points of the human body. The control of pressure in this points to be implemented in real time by an arduino mega controller board. Then the simplified control system is tested on the designed bed. The air inside the airbags placed at the pressure points according to the pressure sensor values connected to the designed system is changed by the compressor. It has been observed that the pressure values decreased by an average of 8-11% by inflating the balls at the pressure points in the designed patient bed system In this way, pressure ulcers occurring at pressure points can be reduced and pressure ulcers can be prevented.
Highlights
Nowadays, depending on factors such as sedentary lifestyles and unhealthy eating disease has increased
The aim of this study is to investigate whether the pressure at the pressure points decreases or not automatically thanks to the designed bed system
Patient bed modeling, simulation, design and application were performed to prevent the development of pressure sores
Summary
Nowadays, depending on factors such as sedentary lifestyles and unhealthy eating disease has increased. If a person lying on bed for a long time without any movement, some injuries will occur on specific pressure points They are localized areas of damage to skin and adjacent tissues due to applied pressure, friction or shear. Infection and prolong wound healing can be seen on inactive patients [1] Conditions such as immobility, skin condition, edema, diabetes, vascular disease, smoking are effective in the formation of pressure ulcers [2]. These formations, are tissue damage that occurs in areas exposed to is chemia (reduced or stopped blood flow) after unbalanced pressure distribution [3]. These ulcers cause difficult treatment processes, and increase the length of hospital stay, decrease the quality of life of patients and their relatives, and increase the cost of health services [46]
