Balloon type primary oxygen supply device

Abstract

The invention discloses a balloon type primary oxygen supply device. The balloon type primary oxygen supply device comprises a disposable oxygen humidifying bottle, oxygen delivery corrugated pipes, a balloon buffer, a four-way opening and an exhausting corrugated pipe, wherein one end of the disposable oxygen humidifying bottle is connected with a high-pressure oxygen delivery opening and the other end is connected with the oxygen delivery corrugated pipes through a conversion opening to guarantee that the humidity of the output high-pressure oxygen is proper and prevent a respiratory tract from being dry and infected; two oxygen delivery corrugated pipes are connected through the balloon buffer, so that the input high-pressure oxygen flow can be buffered, the balloon type primary oxygen supply device has an oxygen storing function, and the breathing state of a patient can be observed at any time through the fluctuation of a balloon; the oxygen delivery corrugated pipes are connected with the respiratory tract of the patient through a square opening below a four-way pipe; a switch is arranged on an opening above the four-way pipe, so that sputum suction can be conveniently performed when necessary in case of emergency; one side of the four-way pipe is connected with the oxygen delivery corrugated pipes, an air suction valve is arranged in the middle of the side, and the high-pressure oxygen enters the respiratory tract of the patient from the air suction valve during inspiration of the patient, and the other side of the four-way pipe is connected with the exhausting corrugated pipe, an exhalation valve is arranged in the middle of the side, and exhaled air of the patient is exhausted from the exhalation valve.

Description

technical field [0001] The invention belongs to the field of medical devices, and specifically provides a safe, effective and convenient hyperbaric oxygen chamber device for patients with tracheotomy, tracheal intubation, or severe coma. Background technique [0002] At present, clinically, when inhaling oxygen in the hyperbaric oxygen chamber used for patients with tracheal intubation, tracheotomy or even severe coma, face mask oxygen inhalation or helmet-type first-level oxygen inhalation method is often used. In the hyperbaric oxygen chamber of the medium, a helmet or oxygen tent is used to cover the upper body of the patient to create a small space, and the helmet or oxygen tent is filled with oxygen through the first-level oxygen supply device in the oxygen chamber to create an approximate pure oxygen environment. The patient breathes gas from the helmet or oxygen tent. The disadvantage is that the gas exhaled by the patient is not easy to discharge, and the oxygen ten...

AI Technical Summary

Problems solved by technology

The disadvantage is that the gas exhaled by the patient is not easy to discharge, and the oxygen tent or helmet is a mixed gas. In fact, the oxygen concentration in this environment cannot reach the ideal concentration at all; if the patient needs to suck sputum, the helmet (or oxygen tent) must be removed to proceed Sputum suction care is complicated and time-consuming; the oxygen in the helmet (or oxygen tent) will leak into the cabin during suction, which will increase the oxygen concentration in the cabin (the oxygen concentration in the cabin is specified in GB12130 "National Standard 5. Technical Requirements" The value should not be greater than 23%), thus increasing the risk of combustion and explosion in the oxygen chamber
