Description

electric monitoring bed

technical field

The invention relates to the technical field of medical instruments, and more specifically, relates to an electric monitoring bed.

Background technique

Some bedridden patients fixed in one posture for a long time will cause physical discomfort and cause bed sores. Other patients who use a ventilator in the intensive care unit do not move for a long time, and are prone to VAP (ventilator pneumonia), so they need to be separated for a while Time to turn over the patient, while raising the patient's upper body to a 30 ° angle inclined position. There are also some patients who need to be treated in a special (head higher than the feet) or reverse special (feet higher than the head) posture for a long time. Patients sometimes need to sit up and read books and newspapers.

Some of the existing nursing beds have the functions of turning over, lying on the back and turning down the legs, but they do not have the function of making the bed surface integrally inclined. Moreover, the angles of turning over, lying on the back, and turning the legs cannot be clearly displayed, and various inclination angles cannot be finely controlled. When the patient turns over, the bed board is divided into left and right parts, and the bed board on the left side or the right side is lifted to support the patient to turn over. Due to the body curve of the human body, when the patient is weak and loose, it will feel uncomfortable to be supported by a plank and turn over.
