DEVELOPMENT OF EVALUATION SYSTEM BY IMAGE PROCESSING FOR BEDSORE PREVENTION AND TREATMENT WHICH CAN BE USED ON BEDSIDE

研制了一套可在床边使用的压疮防治图像处理评价系统。本研究的目的是评价老年关节挛缩症患者床上压力分布情况。用触觉传感系统测量30°仰卧位和侧位的压力分布。我们对肌挛缩症患者的合适位置进行了评估。在仰卧位和侧位30度时，肌挛缩症患者的身体支撑面积小于非肌挛缩症患者，这是因为关节痉挛使患者的肢体支撑力降低。有关节挛缩症的患者与无关节挛缩症的患者相比，身体压力集中。由于肌挛缩程度不同，有必要单独考虑身体的位置。

Evaluation system by image processing for bedsore prevention and treatment which can be used on bedside was developed. The aim of this study is to evaluate of pressure distribution in bed for the elderly patient with joint contracture. The pressure distributions in supine and lateral position of 30 degree were measured by using the tactile sensor systems. We evaluated suitable positioning for patients with contracture. In supine and lateral position of 30 degree, the body support area of patient with contracture was smaller than patient without contracture because joint contracture makes the support of lower extremity decrease. The body pressure of the patient with joint contracture was concentrated in comparison with the patient without joint contracture. Since there was a difference in degree of contracture, it was necessary to consider the positioning of the body, individually.
