Anti-bedsore air cushion bed

Abstract

The invention relates to an anti-bedsore air cushion bed, and belongs to the field of medical instruments. The air cushion bed comprises two layers of detachable inflatable mattresses, a tissue bloodflow and pressure synchronous acquisition module, a data transmission module, a controller module, a power supply module and an alarm module. The two layers of detachable inflatable mattresses comprise turning-over layers and multi-independent air bag layers, the turning-over layers achieve the left-right turning-over function of a patient, each multi-independent air bag layer is formed by arranging a plurality of air bag units, and the mattress is divided into three areas including a head area, a back and hip area and a leg area. A tissue blood flow and pressure synchronous acquisition moduleis arranged in each multi-independent air bag layer air bag unit to synchronously acquire the tissue blood flow perfusion condition of the local part of the human body and the surface pressure of thecorresponding part, so that the real-time pressure and skin microcirculation detection of the part of the bedridden patient can be realized, and a blood flow perfusion amount and body surface pressure curve is established; and a safety pressure threshold value is determined, a pressure and time safety area is determined, and airbag pressure adjustment is performed according to a detection resultfeedback formula. The turning-over air cushion and the nursing bed are combined for use, bedsores are prevented for a patient, and meanwhile nursing personnel can push the patient to walk conveniently.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to an anti-decubitus air bed. Background technique [0002] The occurrence of pressure sores is mainly related to external factors such as pressure, shear force, friction and moisture, among which pressure and duration are the most important pathogenic factors. When the patient is in one position for a long time, it will cause the microcirculation of skin tissue, muscle and so on to be blocked. [0003] Chinese patent CN102670374A discloses a detachable fully automatic inflatable anti-decubitus cushion, including a cushion body, an airbag and a gas regulating device. Airbag air supply is a detachable single airbag structure. The middle part of the cushion is provided with a urine wetness alarm sensor, and the gas regulating device is provided with a pressure alarm to realize the alarm of the air leakage of the single air bag. [0004] Chinese patent CN110772385A discloses a flexible...

Problems solved by technology

However, the above-mentioned patents lack the detection of the skin microenvironment of the patient; the fine-tuning of the local pressure cannot be realized for the critically ill patients who are bedridden for a long time and cannot take care of themselves, the effect is not good, and a lot of nursing work is still required
