Description

Medical bed with turning function for patients with severe pneumonia and method thereof

technical field

The invention relates to the technical field of medical devices, in particular to a medical bed with a turning function for patients with severe pneumonia and a method thereof.

Background technique

The severity of pneumonia depends on the degree of local inflammation, the spread of lung inflammation, and the degree of systemic inflammatory response. For example, severe hypoxemia or acute respiratory failure in patients with pneumonia requires ventilation support, or hypotension, shock and other manifestations of circulatory failure and Other organ dysfunction can be identified as severe pneumonia. Severe pneumonia may manifest as respiratory failure, and the nervous system symptoms mainly include listlessness, drowsiness or irritability. In severe cases, disturbance of consciousness, optic disc edema, coma, convulsions, and cerebral herniation may occur, and children may die due to central respiratory failure . Severe pneumonia can often lead to circulatory system involvement, manifested as weak pulse, rapid heart rate, low and blunt heart sounds, aggravated cyanosis, and increased lung rales. Pale complexion, dark and clammy skin, decreased urine output, decreased blood pressure, and prolonged capillary refill time occur in shock and peripheral circulatory failure. When treating or nursing patients with severe pneumonia, medical staff often need to manually turn them over. The existing nursing medical beds generally push the bed board on one side to an inclined position, and then artificially turn the patient onto the flat side bed board. .

The medical bed with rollover function is convenient for the staff to help the patient's body turn to both sides respectively, and is convenient for the staff to adjust the angle of the sponge pad according to the patient's needs. When the patient sits up, it is more comfortable to lean on the sponge pad with his back.

Although this application solves the problems in the background technology to a certain extent, there are the following problems in this application: 1. The patient generally sleeps in the middle of the bed, and before turning over, the patient needs to be moved to one side of the movable board. , There is difficulty in moving the patient; 2, when helping the patient to stand up, the movable plate on the other side is in a flat state, and the patient rotates to a larger corner on the movable plate that is laid flat, which is easy to cause damage to the patient.
