AI Technical Summary

Technical Problem

Under bumpy conditions, water from the humidification bottle in existing oxygen inhalation devices can easily splash into the nostrils, causing choking and airway obstruction, affecting the safety and comfort of trainees.

Method used

An oxygen inhalation auxiliary device was designed, including a bottle body, a cap body, a mounting base, and a fixing mechanism. The staggered arrangement of the air inlet and outlet grooves and the sealing ring prevent the humidifying liquid from splashing in bumpy environments. The fixing mechanism is used to fix the mounting base inside the bottle neck to ensure the stability of the gas passage.

Benefits of technology

It effectively prevents the humidifying fluid from entering the respiratory tract under bumpy conditions, ensuring the safety and comfort of trainees' oxygen intake, improving gas exchange efficiency, and avoiding the risks of choking and airway obstruction.

Abstract

The utility model provides an oxygen inhalation auxiliary device under bumpy conditions, which comprises a bottle body, a bottle neck arranged on the bottle body, a cover body screwed on the bottle neck, the cover body communicated with an oxygen bottle through a mounting pipe, an air inlet pipe arranged in the mounting pipe, an air outlet pipe connected with an oxygen inhalation mask arranged on the cover body, and a mounting seat arranged in the bottle neck, an air outlet groove and an air inlet groove are formed in the upper side and the lower side of the installation base respectively, communicated and staggered, the air inlet pipe penetrates through the installation base and extends into the bottle body, and a fixing mechanism connected with the bottle neck is further arranged on the installation base. When the device is used for breathing under the bumpy condition, gas can enter the mouth and the nose through the gas inlet groove and the gas outlet groove in sequence, and due to the fact that the gas inlet groove and the gas outlet groove are arranged in a staggered mode, splashing of humidifying liquid can be blocked, and the situation that the humidifying liquid enters the respiratory tract and affects normal breathing of people due to bumpy vehicles is effectively prevented.
