Description

A nasal mask for oxygen inhalation

technical field

The utility model relates to the field of medical devices, in particular to a nasal mask for oxygen inhalation.

Background technique

Clinically, when patients use the respiratory humidification therapy device, they generally inhale oxygen by inserting the nasal breathing tube directly into the nostrils. Post-fixation, if the elastic band is too elastic, it will easily lead to ischemia and pressure ulcers in the tightening area. If a fixing band with weak elasticity is used, the nasal breathing tube is fixed by the elasticity of the elastic band itself, and only the nasal guide is used. The treatment method of the breathing tube stuffed into the nasal cavity is easy to slip off when worn for a long time.

Chinese patent CN208989963U discloses a new type of nasal mask for oxygen inhalation. The nasal mask is arranged to fit the outer contour of the user's nose, and the air intake ducts are arranged on both sides of the nasal mask to satisfy the patient's oxygen inhalation, but the nasal mask is fitted with the patient's nose. The long-term contact of the parts caused pressure ulcers, the connection method of the air intake catheter and the nasal mask was not determined, and the problem that the air intake catheter was easy to fall off was not solved.
