Description

Medical nasal oxygen cannula

Technical Field

The utility model belongs to the field of medical equipment, and particularly relates to a medical nasal oxygen cannula.

Background

The nasal oxygen tube is a medical device which is connected with the oxygen therapy system and is used for oxygen inhalation of human body, and when in use, the nasal oxygen tube can be inhaled only by inserting the nasal insertion branch tube into nostril and hanging the tube connected with the two ends of the nasal insertion branch tube on the ears. Usually, when the patient uses the oxygen-absorbing agent, the oxygen-absorbing agent needs to keep continuously to achieve the treatment effect.

However, when wearing the nasal oxygen cannula, the nasal prongs tend to scrape against the nasal cavity, thereby irritating the nasal cavity, causing discomfort or pain to the patient. The nostril size of each person is also different, if the nostril of the patient is too small, the nasal oxygen cannula is difficult to wear, the foreign body sensation is strong, and if the nostril of the patient is too large, the nasal oxygen cannula connection is unstable. In addition, the input oxygen has a certain impulsive force, the nasal cannula is also a single-hole output, and the sudden input oxygen can lead to strong impact feeling of the nasal cavity of a patient when the treatment is started, thereby affecting the treatment comfort level.

In addition, in the oxygen inhalation process, the pipeline of the nasal oxygen tube is hung on the ear all the time, and the pipeline is harder, and also can cause the patient to feel uncomfortable at the ear, and the treatment comfort level is influenced as well. For this reason, there is a need for improvement of the above-mentioned drawbacks.
