Respirator mask capable of preventing pressure injury

Abstract

The invention discloses a respirator mask capable of preventing pressure injury, which belongs to the field of medical instruments. The respirator mask comprises a mask part covering the face of a patient and a negative pressure machine for supplying and infusing oxygen, wherein an air guide pipe is communicated between a breathing part and the negative pressure machine, the mask part comprises achin part, a nose pressing part and an oral cavity part, a side wing of the nose pressing part is provided with a Mobius ring structure, an arc-shaped groove is formed in the surface of the Mobius ring, the two ends of the Mobius ring are bonded with the mask part, and the middle of the Mobius ring is loose. Due to the fact that the Mobius structure is arranged, the skin or wounds on the two sidesof the nose wing of the patient are always located on the surface of the Mobius ring when attached to the Mobius ring structure, the skin or wounds press the Mobius ring inwards at the moment, the skin or wounds are in clearance fit with the arc-shaped grooves, and the pressure on the skin or wounds is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a pressure injury prevention ventilator mask. Background technique [0002] As the interface between the ventilator and the patient, the ventilator mask is in direct contact with the patient. It is a tool used to assist the ventilator in ventilation and plays a pivotal role in the treatment process. Generally, patients need to use the ventilator for at least 6-8 hours. The long-term compression of the mask increases the vertical pressure, which blocks the blood flow in the compression area of ​​the facial mask and is prone to pressure injury. The longer the compression time, the higher the pressure. Sexual injury leads to a higher incidence of ulcers. A retrospective survey of non-invasive positive pressure ventilation patients found that the incidence of facial pressure injury was 25.49% during the use of non-invasive positive pressure ventilation. [0003] At present, in orde...

AI Technical Summary

Problems solved by technology

Due to the medical device-related pressure injury caused by the mask, the patient's skin has wounds or even infection, and it is no longer possible to continue to wear the ventilator mask, which increases the patient's pain and medical expenses (the wound in this technical solution refers to but is not limited to pressure wounds caused by injuries)
