Description

Improvement type oxygen mask

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to an improvement type oxygen mask.

Background

With the increasing aging of the population, the oxygen saturation of blood of many patients decreases to different degrees due to the failure of the respiratory or cardiac function caused by various reasons, the oxygen concentration of the inhaled oxygen needs to be increased in the early stage of the disease to improve the symptom of the anoxia, and the effect of the mask oxygen inhalation is obvious after one of the long-standing treatment methods.

According to the existing oxygen supply mode of the mask, the non-oxygen storage type mask is mainly used clinically at present. However, when the oxygen therapy device is used, the patient often accidentally loosens the oxygen connecting pipe and the oxygen pipe interface due to the change of the body position or other reasons, the oxygen therapy effect of the patient is affected due to the fact that timely intervention is not performed, meanwhile, due to long-term use, the friction between the facial skin and the edge of the mask is prone to pressure damage, the pain of the patient is increased, meanwhile, only 1 hanging rope is insufficient in stability, the hanging rope is prone to slipping, and the curative effect is reduced.

The Chinese patent application: CN201179261Y discloses an air cushion type oxygen inhalation mask, which is an improvement on the original oxygen inhalation mask, and mainly comprises a mask, an oxygen inhalation tube, an inflation inlet, an air cushion, and a head fixing strap, and is characterized in that: the periphery of the face mask is provided with an air cushion which is fixedly connected with the face mask, one side of the face mask is provided with an inflation inlet, and the periphery of the face mask is provided with the air cushion. Although the device can keep the oxygen inhalation concentration of a patient, the oxygen inhalation effect is poor, and the single fixing band makes the fixing effect of the mask unstable, which easily causes the slippage of the mask.

The Chinese patent application: CN209019691U discloses an oxygen inhalation mask, which comprises a mask body, an oxygen therapy tube joint integrally connected with the mask body, 2 elastic band mounting ears integrally connected with the mask body, an elastic band arranged on the mask body by using the 2 elastic band mounting ears, 2 spring buckles and 2 medical silicone tubes; the medical silicon rubber tube is characterized in that 1 elastic band is arranged and is arranged in a mode of bending into 2 paths and knotting the end head, the elastic band penetrates out of the front end parts of 2 elastic band mounting lugs to form 2 hanging parts, and 1 medical silicon rubber tube is respectively sleeved on the 2 hanging parts; the 2 spring buckles are respectively arranged at the positions of the elastic bands at the rear ends of the 2 elastic band mounting lugs by 1; the part of the elastic band which is positioned at the rear end of the 2 spring buckles is sleeved on the cover body in a mode of passing through a triangular area formed by the cover body and the upper end of the oxygen therapy pipe joint. The device mainly is the improvement of the elastic cord on the face guard, though can improve the laminating compactness of oxygen inhalation mask and face, the edge of face guard does not set up the device that can reduce and contact the friction with the patient, simultaneously because long-term the use, the pressure nature damage easily takes place for the friction at facial skin and face guard edge, increases patient's misery, consequently uses not very conveniently.

In view of the above, there is a need for an improved oxygen mask that can increase the wearing comfort of the patient, reduce the skin pressure injury, reduce the accidental slippage, and improve the oxygen therapy effect, but no report on the new improved oxygen mask is found.
