Abstract

The invention discloses a disposable wetting nasal oxygen cannula which consists of an air inlet 1, a wetting pipe 2, an air outlet 3, a wetting pipe bottom cover 7 and an air discharging pipe 12, wherein the air inlet 1 is located at the upper end of the wetting pipe 2; the air outlet 3 is located on the wetting pipe bottom cover 7; a solid wetting substance 6 is arranged in the wetting pipe 2; the disposable wetting nasal oxygen cannula further comprises an air guide pipe 4; the air guide pipe 4 is plugged into the wetting pipe 2 from the air inlet 1; and vent holes 5 are formed in the air guide pipe 4. According to the disposable wetting nasal oxygen cannula, the solid wetting substance replaces conventional wetting fluid, so that the size of a wetting device is reduced, and the wetting device is light in mass, convenient to operate, uniform in wetting of wet oxygen and long in duration, and can filter out pathogenic microorganisms and avoid cross contamination; and the disposable wetting nasal oxygen cannula is required to be used within a set time limit to guarantee the wetting effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable humidified nasal oxygen tube. Background technique [0002] Oxygen infusion is one of the most commonly used rescue or treatment methods in hospitals. A large number of patients, especially critically ill patients, cannot do without oxygen inhalation therapy. As an important conventional medical equipment, oxygen humidification devices are used in large, medium and small hospitals. necessary. The existing humidification devices are all water humidification, which makes the humidification bubble bath sound loud, which in turn affects the patient's rest and sleep quality. In addition, most of the existing humidification devices are humidification bottles, which occupy a large space and affect the use , inconvenient operation, repeated use by patients, easy to cross infection. Contents of the invention [0003] The technical problem to be solved ...
