Description

Technical Field

[0001] The present invention relates specifically to the technical field of remote controllers, and in particular to an oxygen concentrator terminal remote controller and a system thereof that can monitor heart rate and blood oxygen. Background Art

[0002] A diffused oxygen concentrator is a device that improves the external environment of the human body by increasing the oxygen content (oxygen concentration) in a confined space.

[0003] Powered by electricity and using air as the raw material, pressure swing adsorption (PSA) technology is typically employed. This utilizes the properties of molecular sieves (such as lithium and zeolite) that their nitrogen adsorption capacity increases when pressurized and decreases when depressurized, creating a cycle of pressurized adsorption and depressurized desorption. During this process, nitrogen in the air is adsorbed by the molecular sieve, while oxygen is enriched and collected, achieving oxygen-nitrogen separation and continuously producing oxygen for diffusion. The entire oxygen production process is a purely physical adsorption process, devoid of chemical reactions and environmentally friendly.

[0004] Oxygen is thin in the plateau, and diffused oxygen concentrators can increase indoor oxygen concentration, improve the quality of life of plateau residents, reduce altitude sickness, enhance cardiopulmonary function, and enhance immunity. They are a health guarantee for the elderly, children, and patients with chronic diseases; such as hospital wards, sanatoriums, etc., to create an oxygen-rich environment for patients, assist in the treatment of respiratory diseases, cardiovascular diseases, etc., and promote patient recovery.

[0005] Currently, existing remote controls for diffusion oxygen concentrators only provide control functions, but users lack a clear sense of the physical changes they experience after using the concentrator. Hotel guests in high-altitude areas may experience decreased sleep quality due to hypoxia, but lack real-time information about their blood oxygen levels. Patients with chronic respiratory diseases lack objective data to guide adjustments to their oxygen use when using oxygen concentrators. Hotel staff are unable to monitor guests' health status and provide necessary assistance. Summary of the Invention

[0006] The purpose of the present invention is to provide an oxygen concentrator terminal remote control and system that can monitor heart rate and blood oxygen. By integrating heart rate and blood oxygen sensors on the remote control, real-time feedback on the oxygen production effect can be achieved, and staff can remotely learn about the health status of residents through a data interaction network; so as to solve the technical problems raised in the above background technology.

[0019] As a further technical solution of the present invention, the control unit calculates the blood oxygen saturation using the following formula:

[0020]

[0021] Among them, Ired and Iir are the transmitted light intensities of red light and infrared light, respectively, and Ired0 and Iir0 are the reference light intensities, respectively.
