Abstract:
To prevent accidental falls in medical facilities, various types of bed-sensors have been produced by the clinical engineering department of our hospital. In this study a newly developed bed-sensor using a pyroelectric type infrared sensor was evaluated. The features of this bed-sensor are that it costs only 4,000 yen and can be installed anywhere on beds. It was found that the pyroelectric type infrared sensor (AMN13112) made by Matsushita Electric Works served our purpose. We test used the new bed-sensor in the for three months in the patient's ward and in the health care facility for the elderly attached to our hospital, as the systems to monitor patients who are attempting to get up, to prevent patients from leaving the bed unattended, and to replace the conventional floor sensor. As a result, it was formed that the new sensor is very usable in these applications and is also excellent in safety. But when the bed-sensor was installed in a wrong position, it was activated as a typicel nurse call system. For practical use, some improvements are necessary in stabilizing detection distance and precise control of sensitivity.
