Description

An extended oxygen tube to prevent the tongue from falling backwards

technical field

The invention relates to the technical field of medical devices, in particular to an expanded oxygen tube for preventing the tongue from falling backward.

Background technique

Oxygen infusion is a method of inserting special bilateral nasal catheters into both nostrils to inhale oxygen. Its main function is to increase the partial pressure of arterial oxygen, improve the oxygen supply of the human body, and reduce the burden of breathing and circulation caused by compensatory hypoxia. The causes of hypoxia are different, and the effect of oxygen infusion is also different. The effect of oxygen infusion is significant for those who have oxygen absorption disorders or insufficient ventilation due to lung tissue lesions that affect the ventilation function. It has a certain effect, but it cannot fundamentally solve the problem of hypoxia. At present, the following methods are used for oxygen delivery in the market: nasal cannula oxygen supply, mask atomization oxygen supply, oxygen hood, oxygen tent and special oxygen supply method. Generally, when performing oxygen infusion operations, it is necessary to cooperate with a ventilator through an oxygen infusion tube.

Oxygen tubes currently on the market are not firmly fixed during use and are easy to slip, and long-term wear can easily form pressure sores on the patient's face. It is difficult to meet the oxygen supply requirements of the mask and the atomized oxygen supply of the mask. Therefore, we propose a more practical extended oxygen delivery tube that prevents the tongue from falling back.
