Description

Technical Field

[0001] The present invention relates to the fields of architectural environment and respiratory medicine, and more particularly to a wearable device for an oxygen supply system and a diffuse oxygen supply system. In particular, the present invention relates to a wearable device for an oxygen supply system and a diffuse oxygen supply system that regulates the oxygen partial pressure of inhaled gas. Background Art

[0002] Because atmospheric pressure at high altitudes is lower than at sea level, the partial pressure of inspired oxygen decreases while the volume fraction of oxygen in the air remains unchanged. When the partial pressure of inspired oxygen drops below normal pressure and normoxic conditions, it reduces blood oxygen saturation, leading to hypoxemia and acute and chronic altitude sickness, which significantly impacts the production and daily lives of those living at high altitudes. This is particularly true during sleep, as the brainstem-driven autonomous breathing function is affected, leading to central apnea and hypopnea, and also to problems like Cheyne-Stokes respiration, severely impacting sleep quality and quality of life for those living at high altitudes.

[0003] Diffuse oxygen supply in rooms offers a method for increasing the inspired oxygen partial pressure (POP) of indoor air. While maintaining a constant low-pressure environment, it increases the volume fraction of oxygen in the air, thereby increasing the POP. However, currently available diffuse oxygen supply devices primarily provide oxygen continuously upon activation or release a fixed amount of oxygen into the room at fixed intervals. This fixed, "static" oxygen supply strategy cannot meet the "dynamic" needs of individuals in real time, resulting in both insufficient and excessive oxygen supply. When the released oxygen is insufficient to meet the oxygen needs of individuals in the room, the oxygen supply needs to be increased and maintained for a period of time to maintain the required POP. When the released oxygen exceeds the POP, the oxygen supply needs to be reduced or even suspended. This diffuse oxygen supply adjustment method, which is based on the actual "dynamic" needs of individuals, is a more scientific and economical approach. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0022] Example 1

[0023] According to the wearable device of the oxygen supply system provided by the present invention, Figure 1 As shown, it includes: a headband 1, a flexible bandage 2, an inhaled gas oxygen partial pressure analyzer 3 in the respiratory zone, an oxygen volume concentration monitoring probe 4, an atmospheric pressure monitoring probe 5, a rigid branch tube 6, a flexible branch tube 7 and a nasal airflow monitoring probe 8. The rear end of the headband 1 is connected to the flexible bandage 2, and the flexible bandage 2 is placed in the occipital lobe area of ​​the brain. The flexible bandage 2 can be used to adjust the head circumference when worn.

[0024] A respiratory zone inhaled gas oxygen partial pressure analyzer 3 is installed at the front end of the headband 1. An oxygen volume concentration monitoring probe 4 and an atmospheric pressure monitoring probe 5 are provided on the respiratory zone inhaled gas oxygen partial pressure analyzer 3. The shape of the respiratory zone inhaled gas oxygen partial pressure analyzer 3 is adapted to the frontal lobe area of ​​the brain. The respiratory zone inhaled gas oxygen partial pressure analyzer 3 is placed in the frontal lobe area of ​​the brain for measuring and calculating the inhaled gas oxygen partial pressure value.

[0025] A rigid branch tube 6 is connected to the side of the headband 1, which is connected to a nasal airflow monitoring probe 8 via a flexible branch tube 7. The flexible elbow 7 is placed in the nose and mouth area to adjust the position of the nasal airflow monitoring probe 8 at the nasal air outlet. The nasal airflow monitoring probe 8 is used to monitor nasal airflow during sleep and determine whether central apnea and hypopnea events have occurred.

[0026] Example 2

[0027] The utility model provides a diffuse oxygen supply system, such as Figure 2 As shown, the wearable device including the oxygen supply system in Example 1 further includes a wall-mounted diffuse oxygen supply device 9 and a remote controller 10. The remote controller 10 is connected to the respiratory zone inhaled gas oxygen partial pressure analyzer 3 and the wall-mounted diffuse oxygen supply device 9 via infrared signals, and the respiratory zone inhaled gas oxygen partial pressure analyzer 3 is connected to the wall-mounted diffuse oxygen supply device 9 via Bluetooth.

[0028] Before going to sleep, the user manually operates the wall-mounted diffuse oxygen supply device remote control 10 to set the sleep mode and activate the respiratory zone inhaled gas oxygen partial pressure analyzer 3. The respiratory zone inhaled gas oxygen partial pressure analyzer 3 measures and calculates the human body's inhaled gas oxygen partial pressure value. The respiratory zone inhaled gas oxygen partial pressure analyzer 3 includes two monitoring probe assemblies: an oxygen volume concentration monitoring probe 4 and an atmospheric pressure monitoring probe 5. The oxygen volume concentration monitoring probe 4 and the atmospheric pressure monitoring probe 5 respectively obtain the oxygen volume concentration value and the atmospheric pressure value. The two values ​​are multiplied to calculate the inhaled gas oxygen partial pressure value. The inhaled gas oxygen partial pressure value is used as the input signal source, and the wall-mounted diffuse oxygen supply device 9 is connected and adjusted via Bluetooth to release oxygen flow and concentration. When the oxygen partial pressure value of the inhaled gas is greater than 110 mmHg, indicating that the physiological equivalent altitude is approximately lower than 3000 m, the volume concentration of oxygen released by the wall-mounted diffuse oxygen supply device 9 is set to 23%, and the flow rate is set to 2 L / min; when the oxygen partial pressure value of the inhaled gas is between 85 and 110 mmHg, indicating that the physiological equivalent altitude is approximately between 3000 and 5000 m, the volume concentration of oxygen released by the wall-mounted diffuse oxygen supply device 9 is set to 25%, and the flow rate is set to 5 L / min; when the oxygen partial pressure value of the inhaled gas is less than 85 mmHg, indicating that the physiological equivalent altitude is approximately higher than 5000 m, the volume concentration of oxygen released by the wall-mounted diffuse oxygen supply device 9 is set to 27%, and the flow rate is set to 8 L / min.

[0029] When this embodiment is in use, the nasal airflow monitoring probe 8 continuously monitors the nasal respiratory airflow. When the nasal airflow signal is detected to be greater than or equal to 90% lower than the airflow rate in the previous second and the duration is greater than or equal to 10 seconds, it is considered that a central apnea event has occurred. Regardless of the value of the oxygen partial pressure of the inhaled gas, the wall-mounted diffuse oxygen supply device 9 forcibly releases oxygen at a flow rate of 10 L / min with a volume concentration of 30%. When the nasal airflow signal is detected to be greater than or equal to 30% lower than the airflow rate in the previous second and the duration is greater than or equal to 10 seconds, it is considered that a central respiratory hypopnea event has occurred. Regardless of the value of the oxygen partial pressure of the inhaled gas, the wall-mounted diffuse oxygen supply device 9 forcibly releases oxygen at a flow rate of 8 L / min with a volume concentration of 27%.
