A control circuit for a body position rotation instrument is controlled by a single chip microcomputer (U2), and comprises an air inflation circuit, a deflation circuit, a digital body position sensor circuit, an air bag pressure detection circuit, a voltage stabilizing circuit, a battery electronic quantity detection circuit, and an acousto-optic alarm circuit. A digital body position sensor determines a body position change of a patient, and the body position of the patient is adjusted by inflating or deflating a back air bag of the patient, so that the patient keeps in a lateral decubitus. The body position rotation instrument can improve the sleep condition of a patient without affecting the sleep quality of the patient, and is suitable for a patient with an obstructive sleep apnea. |
