Pressure sore preventing auxiliary breathing machine adapting to body position changes

By designing the breathing mask tracking follow-up structure, the breathing tracheal retraction structure and the breathing mask timing loose structure in the ventilator, the problem that the tracheal is easily folded or pulled when the position of the ventilator changes, and facial discomfort and pressure ulcers caused by long-term tension of the breathing mask is avoided, thus achieving more efficient and comfortable use of the ventilator.

AI Technical Summary

Technical Problem

When the patient's position changes, the respiratory hose is easily folded or excessively pulled, causing the ventilator to fail to supply air normally, and even causing the patient to breathe blockage; at the same time, wearing the respiratory mask for a long time will cause facial discomfort and pressure ulcers.

Method used

A pressure-proof ulcer assisted ventilator that adapts to changes in position is designed, using a breathing mask tracking follow-up structure, a breathing tracheal retracting structure and a breathing mask timing loosening structure, which can automatically adjust and relax through wireless signals and pressure sensing membranes.

Benefits of technology

It effectively avoids the respiratory trachea being folded or excessively pulled due to changes in body position to ensure smooth trachea; at the same time, by regularly relaxing the pressing surface of the respiratory mask, discomfort and pressure ulcers caused by long-term pressure on the face are avoided, and the comfort of the ventilator is improved.

Abstract

The invention relates to an anti-pressure-sore auxiliary breathing machine adapting to body position changes, which belongs to the technical field of medical instruments and comprises a breathing machine main body, a body position tracking slide rail, a breathing tube retracting and releasing device, an anti-bending air tube, a positioning breathing mask, an automatic releasing and fixing belt and a central controller. By arranging the auxiliary breathing machine with the real-time automatic adjusting structure for the air pipe and the timing releasing structure for the breathing mask at the same time, the position of the mask is tracked through the position signal emitter, and the anti-bending air pipe is adjusted in combination with the body position tracking sliding rail and the breathing pipe retracting and releasing device; the fixing belt is electrically controlled, so that the position and the extension length of the trachea can be automatically adjusted according to the face movement of a patient, the phenomenon that the trachea is pressed and folded or is excessively stretched and tightened is avoided, and the trachea is ensured to be continuously and smoothly used normally; the pressing and attaching face of the breathing mask can be loosened at regular time, and the using comfort degree of the breathing machine is improved.
