Intelligent oxygen supply system

Abstract

The intelligent oxygen supply system comprises a physiological parameter acquisition module, a respiratory signal detection module, a control module and an oxygen supply module, one end of the oxygen supply pipeline is connected with the oxygen bottle, and the oxygen supply pipeline is used for supplying oxygen in the oxygen bottle into the oxygen supply pipeline; the second end of the oxygen supply pipeline is connected with the three-way pipe fitting through a gas path; one branch of the three-way pipe fitting is an oxygen outlet which is connected with the oxygen mask; the electromagnetic valve is arranged on the oxygen supply pipeline; the breathing signal detection module is connected with the other branch air path of the three-way pipe fitting and is used for collecting breathing air pressure information of the user; intelligent and accurate oxygen supply is performed through accurate judgment of the breathing state of a user, real-time calculation and control of the oxygen demand of an oxygen uptake person, the oxygen supply amount is strictly controlled, real-time control is performed according to the oxygen demand of a wearer, the oxygen utilization rate and the oxygen utilization rate of the oxygen uptake person are improved, and the oxygen supply efficiency is improved. And meanwhile, various physiological parameters of the user are monitored in real time, so that the personal safety of the user is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic control of oxygen flow, in particular to an intelligent oxygen supply system. Background technique [0002] The atmosphere in high-altitude areas is characterized by low pressure and low oxygen. As the altitude increases, the air becomes thinner. Workers in high-altitude areas will experience symptoms of altitude sickness such as headaches, nausea, vomiting, and unresponsiveness. Therefore, additional oxygen Inhalation to maintain the normal operation of body functions is of great significance for performing important work or military work in high altitude areas. Many workers in high-altitude areas will carry oxygen cylinders or oxygen bags with them for oxygen supply, but the traditional oxygen supply mode causes unnecessary waste of oxygen and cannot be used for a long time. Therefore, automatic adjustment of oxygen supply becomes a better choice. [0003] However, the pulsed oxygen supply sy...

Many workers in high-altitude areas will carry oxygen cylinders or oxygen bags with them for oxygen supply, but the traditional oxygen supply mode causes unnecessary waste of oxygen and cannot be used for a long time. Therefore, automatic adjustment of oxygen supply becomes a better choice

[0003] However, the pulse oxygen supply system currently on the market has the disadvantages of low response sensitivity, sometimes not supplying oxygen during inhalation, and the amount of oxygen supply cannot be changed according to the needs of the human body.

For example, the existing pulse oxygen supply system adopts the method of pulse oxygen supply at fixed time intervals, which cannot automatically match the breathing of the user; some pulse oxygen supply systems require the user to manually adjust the oxygen supply according to their own feelings. Waste of user time and poor utilization of oxygen
