Oxygen tube

Abstract

The invention belongs to the technical field of medical equipment. In order to solve the problem that tiny water droplets are easily produced inside the current oxygen inhalation tube to choke the patient or irritate the patient's respiratory tract, and it is easy to explode when discounted, the present invention proposes an oxygen inhalation tube, which includes an upper connecting pipe, an air-water separation device and a lower connecting pipe The gas-water separation device includes a holding tube and a filter tube, the filter tube is located inside the containing tube, the upper end of the filter tube is provided with a gas-water separation sheet, and the lower end of the filter tube is provided with a circular connection Surface; the pipe wall of the containing pipe is provided with a drainage pressure relief valve, the upper end of the containing pipe is connected with the upper connecting pipe, the lower end of the containing pipe is connected with the lower connecting pipe, and the lower connecting pipe is provided with a nasal suction pipe. The oxygen inhalation tube of the present invention can remove the tiny water droplets inside the oxygen inhalation tube, so as to avoid the tiny water droplets from choking the patient or irritating the patient's respiratory tract. Safety of Oxygen and Oxygen Therapy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an oxygen inhalation tube. Background technique [0002] Oxygen inhalation is a commonly used treatment method in clinic. It is used to correct hypoxia, increase arterial blood oxygen partial pressure and oxygen saturation level, and promote metabolism. It is one of the important methods for auxiliary treatment of various diseases. At present, the equipment used for oxygen inhalation mainly includes oxygen source, oxygen humidifier, and oxygen inhalation tube. Among them, the oxygen humidifier is used to humidify oxygen, that is, to add water vapor to the oxygen to keep the patient's trachea moist. Increase the oxygen intake time to increase the oxygen intake, improve blood oxygen saturation, and prevent the occurrence of cerebral hypoxia. At present, there are two problems with the oxygen inhalation tube used for oxygen inhalation. One is that the oxygen inh...

Problems solved by technology

[0003] In order to solve the problem that tiny water droplets are easily produced inside the current oxygen suction tube, which can choke the patient or irritate the patient's respiratory tract, and easily explode when discounted, the present invention proposes an oxygen suction tube, which can remove the fine water droplets inside the oxygen suction tube. beads to avoid choking on the patient or irritating the patient's respiratory tract. At the same time, the oxygen inhalation tube will automatically release pressure when the air pressure rises due to discounts, which will ultimately greatly improve the safety of oxygen inhalation and oxygen therapy for patients.
