Abstract

The invention discloses a ventilator mask for preventing pressure injury in the field of medical equipment. The ventilator mask includes a mask part covering the patient's face and a negative pressure machine for supplying oxygen. The trachea, the mask part includes a jaw, a nose-pressing part and an oral cavity, the flanks of the nose-pressing part have a Mobius ring structure, and the surface of the Mobius ring is provided with an arc-shaped groove, and Both ends of the Mobius ring are bonded to the mask, and the middle part of the Mobius ring is loose. Since the Mobius structure is set, the skin or wound on both sides of the patient's nose is always on the surface of the Mobius ring when it fits the Mobius ring structure. Pressing inward, the skin or wound cooperates with the gap of the arc-shaped groove, reducing the pressure on the skin or wound.

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...
