Air cushion bed based on pressure change rate

Abstract

The invention discloses an air cushion bed based on a pressure change rate. The air cushion bed comprises a detection module, a data processing module and an execution module. The detection module is provided with a pressure sensor, an excrement and urine sensing device and an air pressure sensor, the pressure sensor is used for detecting the pressure and controlling the inflation and deflation rates of the air cushion bed according to the pressure change rate, the excrement and urine sensing device monitors whether a patient suffers from incontinence or not, the air pressure sensor detects the inflation and deflation state of the air cushion, and safety is guaranteed. The data processing module carries out remote data transmission by using Zig Bee, carries out data processing on received detection data by using an RANSAC algorithm, and carries out PWM (Pulse-Width Modulation) automatic adjustment on the inflating and deflating speed according to the processed data. The execution module comprises an upper-layer air cushion and a lower-layer air cushion, and body position changes such as left-side turning over, right-side turning over and sitting up are achieved through the combined action of inflation and deflation of the upper-layer air cushion and the lower-layer air cushion. Compared with a traditional air cushion bed, the air cushion bed has the advantages that the inflation and deflation rate of the air cushion can be automatically adjusted, the comfort of a patient is greatly improved, and greater convenience is brought to medical staff.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an air mattress based on a pressure change rate. Background technique [0002] At present, in various hospitals, there are many critically ill patients with limited mobility and long-term bed rest leading to decubitus ulcers. Due to the long-term troubles of the disease, many patients are fat or swollen, and they are overweight. When the patients need to turn over, the medical staff need to expend a lot of energy and physical strength to help the patients. In response to this problem, those skilled in the art have developed an air mattress that assists medical personnel to assist the patient to turn over, but the inflation and deflation speed of the existing air mattress is too slow or too fast, which often makes people feel uncomfortable, and sometimes even because of a malfunction This leads to a sudden change in the inflation and deflation speed of the air mattress; in additio...
