AI Technical Summary

Technical Problem

During the use of nasal oxygen cannulas, waste gas in the nasal cavity mixes with oxygen, affecting the cleanliness of the oxygen and causing discomfort when inhaling oxygen.

Method used

A nasal oxygen tube with ventilation function was designed, including an adjustment mechanism, an adsorption mechanism, and a ventilation mechanism. A fan maintains a negative pressure in the main ventilation tube, a ceramic plate regulates the oxygen temperature, the adsorption mechanism adsorbs nasal mucus, and honeysuckle extract is used to improve nasal comfort.

Benefits of technology

It effectively prevents exhaust gas from mixing with oxygen, optimizes oxygen inhalation comfort, increases oxygen temperature, reduces nasal discomfort, adapts to different patients' nostril spacing, and is more comfortable for long-term use.

Abstract

This invention discloses a nasal oxygen cannula and a ventilation method with ventilation function, including an adjustment mechanism. An adsorption mechanism is movably connected to the adjustment mechanism, and both the adsorption mechanism and the adjustment mechanism are connected to a ventilation mechanism. The adjustment mechanism includes a first nasal cannula and a second nasal cannula, with the adsorption mechanism movably engaged with both the first and second nasal canns. The ventilation mechanism includes two ventilation branches, each with a second perforation on its inner top wall. A first ventilation hole is provided on one inner side of the adsorption mechanism and connected to the ventilation branch. First perforations are provided on the inner bottom walls of the first and second nasal canns, with the first perforation located directly above the second perforation. Ceramic plates are fixedly connected to both the first and second perforations. The nasal oxygen cannula and ventilation method disclosed in this invention can optimize the comfort of oxygen inhalation while preventing waste gas from mixing with the supplied oxygen.
