Abstract
Description
Technical Field
[0001] This utility model belongs to the field of non-invasive ventilator oxygen supply mask wearing technology, specifically relating to a non-invasive ventilator oxygen supply mask fixing device. Background Technology
[0002] In the medical field, non-invasive ventilators are an important respiratory support device and are widely used in the treatment of various respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and acute respiratory failure. Non-invasive ventilators deliver oxygen and / or positive pressure air to the patient's airway through an oxygen supply mask to assist or replace the patient's spontaneous breathing and improve the patient's ventilation and oxygenation function. However, existing technologies for fixing oxygen supply masks for non-invasive ventilators have many problems. Traditional fixing methods often use headbands or straps, which can easily lead to poor fit between the mask and the patient's nose and face, resulting in inadequate fixation. Improper fixation can also cause gaps between the mask and the face, allowing oxygen to leak out. The working principle of non-invasive ventilators requires a certain positive pressure inside the oxygen supply mask to ensure that oxygen can smoothly enter the patient's respiratory tract. However, due to an insecurely fixed mask, the pressure inside the mask often fails to reach the set pressure, thus affecting the treatment effect. Therefore, this invention proposes a fixing device for oxygen supply masks for non-invasive ventilators. Utility Model Content
[0003] The purpose of this invention is to provide a fixation device for a non-invasive ventilator oxygen supply mask, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a non-invasive ventilator oxygen supply mask fixing device, comprising... An elastic mesh cap with an open bottom is fitted over the patient's head. The elastic mesh cap covers the non-invasive ventilator oxygen supply mask worn on the patient's face. The surface of the non-invasive ventilator oxygen supply mask is provided with a tube seat, and the top of the tube seat is connected to a top tube that extends to the outside of the elastic mesh cap. The surface of the elastic mesh cap has eye notches and chin notches. And an arc-shaped sponge pad that is fitted onto the top surface of the jacking pipe and fits into the elastic mesh cap.
[0005] Preferably, the surface of the elastic mesh cap has a welt between the eye and chin notches, and the first Velcro strap on the surface of the non-invasive ventilator oxygen supply mask passes through the welt and attaches to the surface of the elastic mesh cap.
