Pressure sore preventing bed provided with feedback information

Abstract

The invention disclose a pressure sore preventing bed provided with feedback information. The bed comprises a bed frame, an air container, an inflation and deflation device, a compound air cushion anda sponge mat. According to the bed, by arranging the compound air cushion on the rigid air container, detecting the stress state of each air bag through wireless pressure sensor chips, obtaining theportions, under pressure for a long term, of a bedridden patient, feeding the information back to a numerically-controlled detection instrument through the wireless pressure sensor chips and controlling and adjusting the air pressure of each air bag of the compound air cushion through the numerically-controlled detection instrument, the contact portions of a mattress and the bedridden patient arechanged, so that prevention, alleviation and treatment of the condition of the patient with pressure ulcers are achieved. The bed has the advantages that the structure is simple, operation and use areconvenient, the precision of the positions of the air bags is high, and the effects of prevention and treatment are good.

Description

technical field [0001] The invention relates to a medical and health care device, which is used for the rehabilitation and auxiliary treatment of patients, especially a pressure sore prevention bed provided with feedback information. Background technique [0002] Pressure ulcer is a serious problem that harms bedridden patients for a long time. It is unavoidable in hospitals, nursing homes, wheelchairs and family beds. At present, there is no effective method for preventing pressure ulcers that can be widely used. We can only rely on the guidance of clinicians to take preventive measures measures to reduce and slow down the likelihood of developing pressure ulcers. Once a patient develops a pressure ulcer, doctors need to diagnose and treat it according to the severity of the condition, which is expensive and painful for the patient. For long-term bedridden patients, how to prevent and alleviate pressure ulcers in the early stage is an urgent task to solve the problem. In ...

Problems solved by technology

In order to solve this problem, people have invented anti-pressure sore mattresses, which have achieved certain effects. For example, the anti-pressure sore mattress of patent No. 201610914906.3 uses self-excited oscillating flow heat pipes, which has a complex structure and is difficult to realize. If it is partially damaged, It is not easy to maintain and has no feedback mechanism; the functional mattress with air pressure sensor used in the patent No. 201320488575.3, due to the irregular deformation of the air bag will affect the air pressure measurement results, resulting in chaotic capture of the treatment target, and the signal transmitted by the air pressure sensor The error is large, it is difficult to obtain the ideal physical therapy effect
