Low-power-consumption oxyhemoglobin saturation value following oxygen generation device

Abstract

The invention relates to the technical field of oxygen generation, in particular to a low-power-consumption oxyhemoglobin saturation value following oxygen generation device and method. Comprising a control system for receiving a signal value and generating a control signal; and a pressure generating assembly for pressurizing air; an adsorbent is loaded in the adsorption assembly, and oxygen needed by a user is generated according to the pressure swing adsorption principle; the oxygen conveying pipeline is used for outputting oxygen generated by the adsorption assembly to an oxygen using object; the pipeline drift diameter adjusting assembly is arranged in the oxygen conveying pipeline and used for adjusting the effective drift diameter L of the oxygen conveying pipeline; and the blood oxygen detection assembly is used for detecting a blood oxygen saturation value of a user in real time, determining a target gear according to the blood oxygen saturation value and adjusting the duty ratio P of the pressure generation assembly and the effective drift diameter L of the oxygen conveying pipeline in real time, and power consumption can be reduced to the maximum extent under the condition that the oxygen demand of the user is met.

Description

technical field [0001] The invention relates to the technical field of oxygen production, in particular to a low-power consumption blood oxygen saturation value following oxygen production device and a method thereof. Background technique [0002] With people's continuous pursuit of health, oxygen therapy has gradually entered the public's field of vision, and oxygen generators such as oxygen generators and health care machines have also begun to enter more and more people's homes. The initial oxygen concentrator is relatively large, it is rarely moved, and is usually powered by mains electricity. However, with the diversification of people's usage scenarios, higher requirements are also placed on the oxygen concentrator's ability to adapt to the environment. , Portability is one aspect of oxygen concentrator improvement. [0003] For small and portable oxygen generators, people are no longer limited by the fact that the oxygen generator cannot be moved. When there is a nee...

Problems solved by technology

[0003] For small portable oxygen generators, people are no longer limited by the fact that the oxygen generator cannot be moved. When there is a need to go out, the user can take the small portable oxygen generator to go out at any time, and the user can still perform ideal oxygen therapy when going out. , which makes small portable oxygen generators have more and more market demand, because when going out, small portable oxygen generators are powered by batteries, so the battery power maintenance time directly affects the user experience. And if you want to supply it for a longer time, then the battery is usually bigger, which makes it difficult for the user to carry it out to achieve portability.
