[0002] There are many items in medical examinations that require patients to lie on a medical bed to cooperate with the doctor's operation, including chest and heart examinations. When doing a heart examination, the person being examined usually needs to lie flat, and the examiner uses an instrument to transmit ultrasonic waves to the human body, and then inputs the reflected waves sensed back into the computer instrument. After image processing, the produced image is used as the basis for diagnosis. The existing examination bed is a simple bed structure with a disposable bed sheet laid on it to ensure the patient's hygiene and cleanliness. When examining the patient, it takes a lot of time to adjust the patient's lying posture. The examination can only be carried out after the posture is adjusted. Some elderly patients cannot complete the action independently during the posture adjustment process and need the assistance of medical staff, which further increases the examination time.
