Description

A kind of medical prone air mattress

Technical field

The utility model belongs to the technical field of medical equipment, and specifically relates to a medical prone inflatable mattress.

Background technique

For patients with serious illness, dyspnea, acute respiratory distress syndrome, etc., their pulmonary oxygenation function is very poor. Prone position treatment means that the patient lies on his stomach to breathe. Treatment in the prone position can improve the patient's hypoxic state, improve the ratio of ventilation to blood flow in the lungs, reduce the compression of the lungs, recruit partially atrophied alveoli, improve the ventilation of the patient's lungs, and restore the patient's lungs under the action of gravity. It is beneficial to the drainage of intratracheal secretions and can improve the success of treatment.

Prone components are often used in the prior art. Foam or plastic prone components are placed on the bed. However, they need to be placed on the bed before the patient lies prone. The spacing of each component is only adjusted and placed through visual inspection. Patients with limited mobility will defecate after lying prone. It is difficult to adjust the position again. Prone patients often use the envelope-type turning method when turning over. The auxiliary equipment is too thick and it is inconvenient to turn over. The auxiliary equipment is too thin and cannot reduce pressure. The single height of the prone component is not suitable for a diverse patient population.
