Description

Non-invasive ventilator mask seal decompression pad

technical field

The utility model relates to the technical field of medical devices, in particular to a non-invasive ventilator mask sealing decompression pad.

Background technique

Non-invasive ventilation refers to the respiratory support mode of mechanical ventilation without the establishment of an artificial airway. Traditional respiratory support requires endotracheal intubation or tracheostomy to create an artificial airway. Endotracheal intubation and tracheotomy not only cause trauma to the patient, but also have certain risks during the operation. Due to the complicated operation of endotracheal intubation and tracheotomy, hospitalization is required. According to the survey, the incidence of pulmonary infection after endotracheal intubation for more than 3 days can be as high as 20%. Non-invasive ventilation connects the patient to the ventilator through a mask and is used for the treatment of acute respiratory failure. It is easy to operate and avoids endotracheal intubation. and its tracheotomy operation, which saves patients from endotracheal intubation or tracheotomy, and reduces complications associated with tracheal intubation and its ventilator treatment, such as the incidence of ventilator-related lung infections, prolonged Difficulty in weaning and prolonged hospital stay after ventilator treatment. In short, non-invasive ventilation is simple and easy to operate, medical treatment and nursing are more convenient, the hospitalization time of patients is reduced, and medical expenses are reduced.

At present, patients using non-invasive ventilators in clinical practice often have instrumental pressure ulcers on the nose and face in contact with the non-invasive mask, and due to the size of the face, a part of the air leaks, which cannot achieve the therapeutic effect.

2. In the present utility model, due to the pressure of the ventilator mask, the skin of the nose and face of the patient is red, swollen, ruptured and even the pressure and necrosis of the alar portion of the nose, thereby bringing pain and trouble to the patient. At this time, the decompression pad is an isosceles triangle. , it can fit more effectively with the triangular area of the face, and a decompression sealing airbag is set on the inside of the body of the decompression pad. According to the size of the patient's face, the airbag can be inflated from the air injection port to freely adjust the relationship between the ventilator mask and the airbag. The space ratio of the face enhances the sealing and compression resistance of the ventilator mask. The set nose wing protection groove can effectively prevent the patient from secondary injury caused by the nose wing compression. It prevents the mask from falling off when the patient orally fasts water or wipes phlegm.
