Portable oxygen production and air supply device and method

Abstract

The invention belongs to the technical field of air separation, and particularly relates to a portable oxygen production and air supply device and method. According to the oxygen production and air supply device, a pulse air supply method is adopted, the oxygen supply flow in unit breathing frequency can be changed along with the change of the breathing frequency, but the total oxygen supply amount in unit time is still maintained; along with the change of the breathing frequency, the air supply amount of each time of breathing is synchronously changed, the phenomena of 'air cut-off ' and 'no or insufficient supply' are avoided, and the air supply experience feeling is good; moreover, although the air supply flow in the unit breathing frequency is small along with the increase of the breathing frequency, the total air supply amount still maintains the original air supply flow, so that the oxyhemoglobin saturation can be effectively maintained; moreover, when the air supply breathing frequency is reduced, the endurance time is prolonged by changing the operation load of the device; and the device can be safely and continuously used in various environments.

Description

technical field [0001] The invention belongs to the technical field of gas separation, and in particular relates to an individual soldier's portable oxygen-generating gas supply device and method which can change the oxygen supply flow rate following the breathing rate of the individual personnel. Background technique [0002] As the altitude continues to increase, the oxygen content in the atmosphere (absolute value, g / m 3 ) and partial pressure of oxygen (pressure value, kPa) decrease accordingly, the oxygen content in the blood (blood oxygen saturation) decreases, and the natural reaction of the human body becomes severe, resulting in such as rapid heart rate, slow response, irritability, and decreased immunity and other physical injuries, accompanied by a series of problems such as headache, abdominal distension, hair loss, dyspnea, lack of energy, poor sleep quality, memory loss and even death from pulmonary edema. , Travelers, or Tibetans living on the plateau, effect...

AI Technical Summary

Problems solved by technology

Due to the fixed flow rate of oxygen generating equipment, in order to meet the oxygen supply flow rate required by personnel at higher altitudes, the gas supply capacity of the equipment is required to be higher. Affected by this, the size, volume, weight, required power, and battery life of the concentrator must be adjusted accordingly. The design challenge is huge; although some products are coupled with the design of pulse breathing, in order to reduce the oxygen supply at a unit respiratory rate and reduce the demand for air supply flow of the equipment, it is still a quantitative output gas supply that follows the respiratory rate method, when the respiratory rate changes, it is easy to fail to keep up and cause oxygen supply failure

However, if the air supply follows the respiratory rate, the oxygen supply purity of the concentrator will decrease due to the increase of the air supply flow per unit time, and the blood oxygen saturation cannot be effectively maintained. Therefore, a more effective air supply method is urgently needed solution
