Description

Multi-position bedsore-proof air cushion device with prone cushion

Technical Field

The invention belongs to a device for preventing bedsore or helping a patient turn over, and particularly relates to a multi-position bedsore-preventing air cushion device with a prone cushion, belonging to the technical field of special mattresses for the purpose.

Background

Bedsore, also known as pressure ulcer and pressure sore, is caused by tissue ulceration and necrosis due to continuous ischemia, anoxia and malnutrition caused by long-term local tissue compression. Skin pressure sores are a common problem in rehabilitation and care. According to the reports of relevant documents, about 6 million people die from pressure sore merging symptoms every year; when the patient is locally pressed for a long time, when tissues at the bone protrusion part are pressed, the microcirculation regulating force is weakened, local capillaries are subjected to ischemia, the tissue is pressed more highly, the ulcer forming time is shorter, if the human body is continuously pressed by 8.0kPa, the blood flow in the skin is reduced to 33 percent of normal blood flow, the tissue is pressed for more than 3 hours, tissue damage is generated, and bedsore is caused if the pressure is not relieved.

For normal healthy people, after falling asleep at night, the body position is always changed by ceaselessly turning over, bedsores are avoided, particularly for children, the body position is changed ceaselessly during sleeping at night, but for the elderly with poor physical ability, operation patients and long-lying bed patients, the body position is difficult to change automatically, bedsores are easy to occur, and therefore various air mattresses are also generated on the market for avoiding bedsores except for the fact that nursing staff turns over and wipe bodies ceaselessly.

At present, the lying mode is mainly lying on the back, and in clinical severe patients, especially patients with lung diseases, lying on the back for a long time, accumulated air at the bottom is drawn to the high position due to the fact that accumulated liquid flows to the low position, and the bottom of the lung cannot exchange air for a long time, so that alveolus lesion can be caused, and lung treatment and recovery are affected. Therefore, the patients need to be treated by prone position and prone auxiliary ventilation treatment. At present, the prone position is realized mainly by manually plugging a spongy cushion or a pillow, the physical support for medical care is large, and the pressure of the contact surface of a patient is fixed and can not be flexibly adjusted according to the patient.

Currently, the related products on the market are:

(1) the mattress consists of a strip-shaped inflatable bag, can be flatly placed on a bed, is inflated by an inflator pump, is tightly plugged with an air nozzle cap after inflation is finished, is fixed on the bed by a rope through a perforation, and is paved with a bed sheet.

(2) The fluctuation inflation type bedsore-proof air cushion is composed of a strip-shaped inflatable bag, the air bag is divided into odd-numbered air passages and even-numbered air passages from top to bottom, the two groups of air passages are inflated and deflated circularly about every 10-12 minutes, and the air passages fluctuate after being inflated, so that the air cushion has the functions of massage and ventilation.

(3) The spherical inflated bedsore-proof air cushion consists of regularly arranged spherical air bags capable of being set on bed or chair and capable of moving to support body to reduce the pressure on the surface of the fixed part and shorten the time.

(4) The household medical nursing bed utilizes a hand-operated mechanical arm to adjust the inclination of a left bed plate and a right bed plate so as to achieve the aim of turning over a patient.

Above 4 kinds of conventional air mattress only are used for the patient to face upward the position and the bedsore is prevented in the side position nursing, in the use, all are difficult to realize that the prone position nursing prevents bedsore, are unfavorable for that the patient nurses recovered.
