Pressure injury prevention and control mattress used on flatcar

Abstract

The invention discloses a pressure injury prevention and control mattress used on a flatcar. The mattress comprises an air bed, air pumps, a control device, an electromagnetic valve and a power supplydevice, wherein the air bed is divided into three areas including the areas with small pressure injury risks on the two sides and the area with large pressure injury risks in the middle; two groups of strip-shaped air bags are alternately distributed in the areas on the two sides, and the first air pump conducts inflation and exhaust on the interiors of the two groups of strip-shaped air bags inturn every 8 minutes; on the basis of in-turn inflation and exhaust and according to pressure changes at each position of the air bed, the inflation degree of the second air pump on each position is controlled through a control device. The mattress is economical, practical, comfortable and effective, the requirements of different individuals on the air bed can be met, and the occurrence of pressure injury in the anesthesia recovery period and transferring process of a patient after general anesthesia is effectively prevented; meanwhile, the mattress is applicable to emergency rescue rooms andthe 120 first-aid transferring process.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a pressure injury prevention mattress used on a flat car. Background technique [0002] Pressure injury is a common problem faced by health care institutions around the world. It not only brings great pain to patients, seriously reduces their quality of life, but also increases medical costs and consumes a lot of medical resources. Surgical patients are high-risk groups of pressure injury, and its incidence rate is as high as 4.7%-66.0%. Patients with general anesthesia after surgery generally have to experience an anesthesia recovery time of 60-80 minutes on a flat car. Due to the residual effects of various anesthetics and muscle relaxants, plus preoperative malnutrition, long-term braking during surgery, and surgical trauma , blood loss, fluid loss, and pain. At this time, the risk of pressure injury in patients is greatly increased. Common methods for preventing ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the anesthesia recovery period, the patient's vital signs are still unstable, and life-threatening may occur at any time. At this time, moving the patient is more likely to be dangerous. In addition, due to the manpower and space in the anesthesia recovery room, it is difficult to turn the patient over

[0004] 2. Sponge pads commonly used in clinical practice have poor air permeability and are prone to local depressions for a long time, and the patient's sweat and blood are easy to accumulate, which will not only cause local skin moisture and tissue bruises, but also lead to pressure injuries. May also cause nosocomial infection

[0005] 3. Elastic foam, silicone or gel mattresses are only used by very few hospitals in China because they are expensive and impractical

Patients on the flat car can only lie in the supine position, so the risk of pressure injury in the sacral coccygeal region of patients on the flat car is significantly higher than other parts. In addition, different patients have different body shapes, and the supporting pressure required by their bodies is also different, but the commonly used clinical pressure Sexual injury prevention mattresses have a fixed shape, and the position of each pressure support point after inflation is also fixed. The patient's experience is poor, and the effect of preventing pressure injury is limited; the intelligent air mattress with adjustable pressure can be adjusted according to the pressure of various parts of the human body. The inflated pressure of the air mattress can effectively prevent the occurrence of pressure injury, but it is expensive, has poor practicability, and is not suitable for clinical application

[0007] In addition, the existing air mattresses can only use alternating current, and cannot be used when there is no alternating current or the alternating current is cut off. on the bed, more prone to pressure injuries
