Double nasal oxygen cannula direct oxygen feeding method and double nasal oxygen cannula

Abstract

The present invention relates to a medical device and aims to provide an improvement of a nasal oxygen cannula oxygen feeding method. The oxygen feeding method has characteristics of being simplifiedin operation steps, saving production cost and reducing labor consumption; and the provided nasal oxygen cannula has characteristics of being strong in bending resistance and ensuring oxygen supply stability and unobstruction. Technical schemes are as follows: the double nasal oxygen cannula direct oxygen feeding method comprises the following steps: 1) a connector directly communicates one ends of two small tubes to an oxygen source to introduce oxygen, and the other ends of the two small tubes communicate with a nasal plug as an air supply end for patients; and 2) inner walls of the two small tubes are evenly distributed with a plurality of reinforcing ribs extending along length to improve the bending resistance of the small tubes.

Description

technical field [0001] The invention relates to a medical appliance, especially a method and appliance for oxygen inhalation. Background technique [0002] Nasal oxygen cannula is a commonly used oxygen supply medical device in medical units, and it consumes a lot as a disposable product. Existing oxygen delivery methods are (see image 3 ): Connect one end of the thicker single tube 6 to an oxygen source (such as bottled oxygen) through the joint 4 after the oxygen is drawn out, then connect the other end of the single tube to two nasal plugs through the conversion joint 5 A small tube is used to provide oxygen to the patient through nasal congestion; this method not only requires more operation steps, but also has many parts, resulting in more production costs and labor consumption; and the two small tubes are circular in cross section The thin plastic tube is not strong in bending resistance (it is easy to block the airflow channel when bending), and cannot guarantee the...
