Description

Air-water type pressure sore prevention mattress

Technical Field

The utility model belongs to a mattress, in particular to an air-water type anti-pressure sore mattress.

Background

It was thought in the past that pressure sores were often caused by the patient lying in bed for a long period of time. However, the research shows that no matter the compression caused by any body position, the pressure sore can be generated under the action of enough pressure bearing time and pressure.

The old people are high-incidence people of pressure sores, and investigation shows that more than 70 percent of pressure sore patients come from the old people of more than 70 years old, and not only do the old people suffer from pressure sores in hospitalization and have various complications, and the fatality rate of the old people is more than 50 percent if the old people suffer from infection or septicemia after poor healing. The pressure sores not only affect the recovery of the old patients from the primary disease, but also increase the hospitalization time and the treatment difficulty of the patients.

At present, China has no direct data for reporting medical expenses for treating pressure sores of the old. Relevant statistics in the United states indicate that about 170 million people suffer pressure sores each year and lead to 6000 deaths of patients, with treatment costs reaching $ 10-85 billion. Moreover, the high treatment cost not only brings economic pressure to the families of patients, but also causes heavy burden to the families and the society because the pressure sores are cured slowly and easily repeatedly. However, the population over 60 years old in China exceeds 2.3 hundred million, and how to effectively prevent and treat pressure sores is the main research direction at present.

At present, most of common mattresses for preventing and treating pressure sores are polyurethane gel pads, and the common mattresses are found in clinical use to easily enable the skin of a patient in an operation to be in a wet state for a long time, but increase the risk of pressure sores.

Therefore, how to alleviate the pain of the pressure sore of the patient, timely discover the pressure sore, treat early, prevent early and heal early, and simultaneously can make corresponding nursing work for the medical staff to timely and effectively judge the pressure sore stage, and the reduction of the work load is the problem which needs to be solved urgently at present.
