Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable double-channel oxygen-absorbing nasal mask. Background Art

[0002] Nursing is used to treat patients in medical treatment, and different equipment is used according to different nursing needs. In clinical practice, when patients use oxygen therapy, the traditional methods include mask oxygen inhalation and nasal cannula oxygen inhalation for auxiliary care. Oxygen inhalation is the most commonly used treatment for patients with hypoxia or resuscitation. According to the different oxygen flow rates given by the oxygen therapy plan, nasal oxygen cannula or mask is selected as the main consumables for oxygen therapy.

[0003] After searching, a Chinese patent with announcement number CN214435771U discloses an oxygen nasal mask, including a nasal mask body, an airway tube, an internally threaded sleeve, and a fixing belt. The fixing belt is arranged on the left and right sides of the nasal mask body. The airway tube is provided with a connector, which extends into the internally threaded sleeve. A limiting chuck is provided at the upper end of the connector, and a step hole is provided at the lower end of the internally threaded sleeve. The outer diameter of the limiting chuck is larger than the inner diameter of the step hole. The nasal mask body matches the outer contour of the nose. One to two nasal tubes are provided at the lower edge of the nasal mask body, and the lower ends of the nasal tubes are connected to the internally threaded sleeve through threads.

[0004] However: In the prior art, ordinary oxygen therapy patients generally use nasal oxygen tubes, which are generally only suitable for low-flow oxygen supply. If the flow rate is relatively large, people cannot tolerate it, resulting in nasal discomfort, dry nasal mucosa and even bleeding. At the same time, there are disadvantages such as the nose tip is easily blocked by nasal mucus and is not easy to clean. The mask oxygen inhalation method is to cover the cup tightly on the mouth and nose and fix it with an elastic band. Its advantages are that the patient has less discomfort, no mucosal irritation and dry blowing feeling. However, the disadvantage is that the oxygen consumption is 1-2 times greater than that of the nasal oxygen tube, and there are many inconveniences in language communication, eating or expectoration during oxygen therapy, and the patient's acceptance is also poor; and patients with oral and nasal indwelling gastrointestinal tubes cannot use it, and cannot undergo gastroscopy, which has clinical limitations. To this end, based on long-term clinical observation and practice, combined with the advantages and disadvantages of both, a new type of disposable dual-channel oxygen inhalation nasal mask is proposed to fill the clinical gap of this kind of medical material.
