[0046] In particular, the present invention can distinguish the significant influence cycle and the weak interference cycle through the hypoxia influence tendency characterization values corresponding to different hypoxia influence cycles, improving the oxygen utilization efficiency. Moreover, whether to enable the oxygen compensation device can be determined through the reduction amount of the oxygen concentration in the target object area, further improving the oxygen utilization efficiency.

[0054] Please refer to Figure 1 As shown, it is a structural block diagram of the self - regulating diffusive oxygen - rich sleep pillow according to an embodiment of the present invention. The present invention provides a self - regulating diffusive oxygen - rich sleep pillow, which includes a pillow surface, a pillow core, and an oxygen - delivery pipe provided with a plurality of through - holes inside the pillow core, and further includes:

[0055] An oxygen - delivery assembly, which includes an oxygen - delivery pipe for delivering oxygen to the sleep pillow, a storage module connected to the oxygen - delivery pipe for storing the data obtained by a heart - rate sensor and a blood - pressure sensor, and an oxygen - compensation device for increasing the oxygen concentration in each time period of the oxygen - delivery pipe;

[0058] An oxygen supply controller, which is respectively connected to the oxygen delivery component, the monitor and the analyzer, includes a clustering unit and a control unit. The clustering unit is used to distinguish the significant impact period and the weak interference period based on the hypoxia impact tendency characterization value corresponding to different hypoxia impact periods;

[0059] The control unit responds to the division result of the clustering unit and monitors the oxygen state in the sleep pillow area, including,

[0060] Determine the oxygen supply characterization parameter of the oxygen delivery tube based on the change amount of the heart rate and blood pressure of the target within a predetermined period and the variance of the oxygen concentration parameter in the sleep pillow area, predict whether there is an abnormality in the oxygen concentration in the target area based on the oxygen supply characterization parameter of the oxygen delivery tube, and determine whether to activate the oxygen compensation device based on the reduction amount of the current oxygen concentration in the target area;

[0061] Or, do not activate the oxygen compensation device.

[0062] Specifically, the present invention provides a self-regulating diffused oxygen-rich sleep pillow, which includes a pillow surface, a pillow core and an oxygen delivery tube, and also includes an oxygen delivery component, a monitor, an analyzer, and an oxygen supply controller. The oxygen is delivered to the oxygen delivery tube of the sleep pillow through the oxygen delivery component. The monitor uses a heart rate sensor and a blood pressure sensor to monitor the heart rate and blood pressure of the target. The analyzer analyzes the historical data monitored by the monitor. Moreover, the hypoxia impact period is identified through the heart rate and blood pressure of the target, and the significant impact period and the weak interference period are distinguished based on the hypoxia impact tendency characterization value, and the oxygen state in the sleep pillow area is monitored to determine the oxygen delivery tube characterization parameter. Based on the oxygen delivery tube characterization parameter, it is predicted whether there is an abnormality in the oxygen concentration in the target area to determine whether to turn on the oxygen compensation device, considering the impact of environmental area differences on the target during the operation of the oxygen-rich sleep pillow, adaptively activate the oxygen compensation device, and then ensure the oxygen supply efficiency and the oxygen condition in the target area.

[0063] Specifically, the present invention is applied to hotel rooms in plateau areas. Commonly, the oxygen delivery component includes an oxygen delivery tube and a storage module. The energy storage module is usually installed on the back of the heart rate sensor and the blood pressure sensor. Due to individual differences in oxygen inhalation of the target, there are differences in the oxygen supply period in the target area. And in some cases, there may also be certain differences in altitude reaction among different target individuals.

[0064] Specifically, the target object is a person with vital signs during implementation, and the target object area is the area around the sleep pillow where the individual is located.

[0065] Specifically, no specific limitations are imposed on the structures of the monitor, analyzer, oxygen supply controller itself, and each unit therein. They may be composed of logical components, and the logical components include field programmable processors, computers, or microprocessors in computers.

[0066] Specifically, a self-regulating diffusive oxygen-rich sleep pillow includes a pillow surface, a pillow core, and an oxygen delivery tube provided inside the pillow core with several through holes. The form of the oxygen compensation device is not limited. A diffusive plate may be provided on the pillow chassis, and the diffusive plate is connected to a guide tube through a one-way valve, and the guide tube communicates with an external gas delivery tube. The surface of the diffusive plate is evenly covered with nozzles. There are gas outlets on the front and air holes on the side of the nozzles. Even if the gas outlet is blocked due to the head pressing down, the air holes on the side can still continue to supply gas. Another form may be to use an oxygen generator to generate oxygen, and the oxygen is delivered to the oxygen delivery tube inside the pillow through a hose. For example, oxygen is generated by a modular membrane separation oxygen generator and delivered to the oxygen delivery tube inside the pillow through a hose. The oxygen generator can directly separate oxygen from the air, and the concentration can reach about 30%, which can effectively increase the oxygen concentration around the pillow. Other forms may also be used and will not be elaborated here.

[0067] Specifically, no specific limitations are imposed on the installation positions of the heart rate sensor and the blood pressure sensor. Each sensor may be installed in different areas of the sleep pillow and will not be elaborated here.

[0068] Specifically, the oxygen detection unit may be a logical component for obtaining information. For example, it may access an oxygen sensor management system to obtain relevant parameters and will not be elaborated here.

[0069] Please refer to Figure 2 As shown in the logical determination diagram for identifying the hypoxic influence period of the embodiment of the present invention. The analyzer of the present invention is used to identify the hypoxic influence period based on the difference between the heart rate and blood pressure of the target object in different historical periods in the storage module, where

[0070] The variance of the ratio of the heart rate of the target object in each historical period to a predetermined heart rate threshold is calculated and determined as the first hypoxic influence factor;

[0071] The variance of the ratio of the blood pressure of the target object in each historical period to a predetermined blood pressure threshold is calculated and determined as the second hypoxic influence factor;

[0072] The sum of the first hypoxic influence factor and the second hypoxic influence factor is determined as the hypoxic influence parameter;

[0073] If the hypoxic influence parameter corresponding to a single historical period is greater than a predetermined variance threshold, it is determined that the historical period is a hypoxic influence period.

[0074] Specifically, the variance threshold is determined based on the average variance of the hypoxia impact parameters obtained within a number of historical periods, and is set to be between 1.15 times and 1.25 times the average variance.

[0075] Specifically, to reflect the monitorability of the oxygen change and its impact on the target object, the historical period is selected within the interval [2 min, 6 min].

[0076] Please refer to Figure 3 as shown, which is the logical decision diagram for analyzing the hypoxia impact tendency characterization value of the embodiment of the present invention. The analyzer of the present invention is used to analyze the hypoxia impact tendency characterization value of the target object within different impact periods based on the change mean value of the oxygen concentration parameters in the target object area, including,

[0077] calculating the ratio of the oxygen concentration parameter in the target object area to the standard oxygen concentration threshold to determine the first historical hypoxia feature;

[0078] calculating the ratio of the change mean value of the oxygen inhalation concentration of the target object to the oxygen concentration change threshold to determine the second historical hypoxia feature;

[0079] calculating the sum of the first historical hypoxia feature and the second historical hypoxia feature to determine the hypoxia impact tendency characterization value.

[0080] Specifically, the change mean value of the oxygen inhalation concentration of the target object reflects the change of the oxygen concentration in each area of the target object under different hypoxia impact periods. The oxygen concentration change threshold is a reference value used to measure whether the degree of this change is significant, and is set to the average change mean value of the oxygen inhalation concentration of the target object within a number of historical periods in implementation. By calculating the ratio, the change threshold can be standardized, which is convenient for comparison and comprehensive analysis with other features.

[0081] Similarly, for the ratio of the oxygen concentration parameter in the target object area to the standard oxygen concentration threshold, the standard oxygen concentration threshold is set to the average value of the oxygen concentration parameters in the target object area within a number of historical periods in implementation. Taking this ratio as the first historical data feature comprehensively considers the change of the oxygen concentration parameter in the target object area under different oxygen concentration impact periods.

[0082] Specifically, by adding the first historical data feature and the second historical data feature, the hypoxia impact tendency characterization value is obtained. This value comprehensively considers the oxygen concentration parameter in the target object area and the change of the oxygen inhalation concentration of the target object and other oxygen concentration parameters under the influence of oxygen concentration in different hypoxia impact periods, and can more comprehensively reflect the hypoxia impact tendency of a single target object under a specific hypoxia impact period.

[0083] Specifically, by analyzing multiple oxygen concentration parameters, the degree of influence of oxygen concentration on the target can be more accurately evaluated. Different oxygen concentration parameters reflect the changes in oxygen concentration in different plateau regions from different perspectives. Considering these parameters comprehensively can reduce the limitations of single-parameter evaluation and provide a more comprehensive and accurate assessment result of the temperature influence.

[0084] Please refer to Figure 4 As shown, it is the logical decision diagram for distinguishing the significant influence period and the weak interference period in the embodiment of the present invention. The clustering unit of the present invention is used to distinguish the significant influence period and the weak interference period based on the hypoxia influence tendency characterization values corresponding to different hypoxia influence periods, including

[0085] If the hypoxia influence tendency characterization value is greater than or equal to the preset influence tendency characterization value, it is determined as the significant influence period;

[0086] If the hypoxia influence tendency characterization value is less than the preset influence tendency characterization value, it is determined as the weak interference period.

[0087] Specifically, the preset influence tendency characterization value, as a key judgment criterion, plays a role in dividing the significant influence period and the weak interference period. In implementation, the preset influence tendency characterization value is selected within the range of [2.15, 2.35].

[0088] Specifically, when the hypoxia influence tendency characterization value is greater than or equal to the preset influence tendency characterization value, it is determined as the significant influence period. This indicates that within this period, the influence of oxygen concentration on the target is relatively significant, which may lead to a large change in the health status of the target. Preferably, the oxygen concentration requirements of each target are different. If the target has a fast oxygen absorption rate, it will cause a decrease in the oxygen concentration in the target area, or if the oxygen concentration in the target area changes too quickly, it may trigger sudden changes in the heart rate and blood pressure of the target, affecting the health and safety of the target.

[0089] Specifically, if the hypoxia influence tendency characterization value is less than the preset influence tendency characterization value, it is determined as the weak interference period. Within this period, the influence of oxygen concentration on the target is relatively small, and the changes in the heart rate and blood pressure of the target are relatively gentle. At this time, the target can sleep in a relatively stable state, and the performance indicators such as the heart rate and blood pressure of the target are relatively stable.

[0090] Specifically, the control unit responds to the division result of the clustering unit, including

[0091] If the partitioning result is a significant impact period, determine the oxygen supply characterization parameter of the oxygen supply pipe based on the change amounts of the heart rate and blood pressure of the target object within a predetermined period and the variance of the oxygen concentration parameter in the target object area. Predict whether there is an abnormality in the oxygen concentration in the target object area based on the oxygen supply characterization parameter of the oxygen supply pipe. Determine whether to activate the oxygen compensation device based on the reduction amount of the current oxygen concentration in the target object area;

[0092] If the partitioning result is a weak interference period, do not activate the oxygen compensation device.

[0093] Specifically, within a significant impact period, the oxygen concentration has a greater impact on the heart rate and blood pressure of the target object. By monitoring the change amount of the oxygen concentration in the target object area, the impact degree of the change in the external environmental oxygen concentration on the heart rate and blood pressure of the target object can be understood. At the same time, the change ratio of the oxygen concentration inhaled by the target object reflects the health changes of the target object individual under different oxygen concentration conditions. Combining these two parameters to determine the oxygen supply characterization parameter can more comprehensively evaluate the impact of the oxygen concentration on the target object in the entire sleep area.

[0094] Specifically, when the changes in the heart rate and blood pressure of the target object rise sharply, it may cause a change in the oxygen concentration inhaled by the target object, thereby affecting the oxygen supply efficiency of the sleep pillow. By analyzing the oxygen supply characterization parameter of the oxygen supply pipe of the sleep pillow, it is possible to predict whether there is an abnormality in the oxygen concentration in the target area of sleep.

[0095] Specifically, within a significant impact period, the usage cost and benefits of the oxygen compensation device need to be considered. The oxygen supply of the oxygen compensation device is an important consideration. If the oxygen concentration in the target object's sleep area brought about by activating the oxygen compensation device is too large, it may lead to waste of oxygen supply and low oxygen supply efficiency. At the same time, the reduction amount of the current oxygen concentration in the target object area needs to be considered. If the reduction amount of the oxygen concentration is large, it may be necessary to activate the oxygen compensation device to reduce the potential safety hazard of the target object individual caused by the oxygen concentration impact.

[0096] Specifically, if the current oxygen concentration in the target object area is normal and the current reduction amount of the oxygen concentration is relatively small, the oxygen compensation device may not be activated, but other measures may be taken, such as issuing an alarm to take drugs to prevent altitude sickness, including drugs such as Rhodiola rosea, acetazolamide, and dexamethasone, to reduce the impact of the oxygen concentration change on the safety of the target object individual.

[0097] Specifically, the control unit is used to determine the oxygen supply characterization parameter of the oxygen supply pipe based on the change amounts of the heart rate and blood pressure of the target object within a predetermined period and the variance of the oxygen concentration parameter in the target object area, including,

[0098] Calculate the ratio of the change amount of the heart rate of the target object to the predetermined heart rate change threshold and determine it as the first oxygen supply parameter feature;

[0099] The ratio of the change in the blood pressure of the target object to the blood pressure change threshold is calculated and determined as the second oxygen supply parameter characteristic;

[0100] The ratio of the change in the oxygen concentration in the target object area to the oxygen concentration change threshold is calculated and determined as the third oxygen supply parameter characteristic;

[0101] The sum of the first oxygen supply parameter characteristic, the second oxygen supply parameter characteristic, and the third oxygen supply parameter characteristic is calculated and determined as the oxygen supply characterization parameter of the oxygen delivery tube.

[0102] To reflect the difference in oxygen concentration requirements, the predetermined heart rate change threshold is set based on the average heart rate value of the target object within the historical period, and is set to be between 0.95 times and 0.98 times the average heart rate value.

[0103] The blood pressure change threshold is set based on the average blood pressure mean value of the target object within the historical period, and is set to be between 0.90 times and 0.95 times the average blood pressure mean value of the target object.

[0104] Specifically, by adding the first oxygen supply parameter characteristic, the second oxygen supply parameter characteristic, and the third oxygen supply parameter characteristic, the oxygen supply characterization parameter is obtained. This parameter comprehensively considers the impacts of the heart rate change, blood pressure change, and oxygen concentration change in the target object area on the health of the target object. Preferably, if all three characteristic values are large, it indicates that the heart rate change, blood pressure change, and oxygen concentration change of the target object all have a greater impact on the target object, and at this time, the oxygen supply characterization parameter will also be large.

[0105] Specifically, the control unit is used to predict whether there is an abnormality in the oxygen concentration in the target object area based on the oxygen supply characterization parameter of the oxygen delivery tube, including,

[0106] If the oxygen supply characterization parameter of the oxygen delivery tube is less than or equal to the preset oxygen supply characterization parameter, it is predicted that there is no abnormality in the oxygen concentration in the target object area;

[0107] If the oxygen supply characterization parameter of the oxygen delivery tube is greater than the preset oxygen supply characterization parameter, it is predicted that there is an abnormality in the oxygen concentration in the target object area.

[0108] Specifically, the preset oxygen supply characterization parameter, as a key reference value for judging whether there is an abnormality in the oxygen concentration in the target object area, is comprehensively determined based on factors such as the healthy mean values of the heart rate and blood pressure of the target object, historical operation data, and the oxygen concentration requirements of the target object. Preferably, through a large amount of analysis of the oxygen inhalation requirements of the same type of target object under different plateau effects, a value that can distinguish whether the oxygen concentration is abnormal is determined.

[0109] Specifically, when the oxygen supply characterization parameter of the oxygen delivery tube is less than or equal to the preset oxygen supply characterization parameter, it is predicted that there is no abnormality in the oxygen concentration in the target area. This means that under the current operating conditions, the changes in oxygen concentration in the target area and the physical signs reflected by the changes in the target's heart rate and blood pressure are within an acceptable range, and the oxygen in the ambient air can also supply oxygen according to the expected performance requirements. Preferably, the changes in the target's heart rate and blood pressure are relatively small, and the impact on the oxygen concentration in the target area is not significant. At the same time, the changes in the oxygen concentration in the target area are also maintained at a relatively stable level, which can meet the target's demand for oxygen inhalation.

[0110] Specifically, if the oxygen supply characterization parameter of the oxygen delivery tube is greater than the preset oxygen supply characterization parameter, it is predicted that the oxygen concentration in the target area is abnormal, which means that the oxygen concentration change in the current area exceeds the acceptable range of the target. This may be due to severe altitude sickness, which has a significant impact on the heart rate and blood pressure of the target, and thus cannot meet the predetermined oxygen supply effect requirements.

[0111] Specifically, the control unit is used to determine whether to activate the oxygen compensation device based on the reduction amount of the current oxygen concentration in the target object area when it is predicted that the oxygen concentration in the target object area is abnormal.

[0112] Specifically, in a photovoltaic energy storage system, when the predicted energy storage effect of the energy storage battery does not meet the predetermined standard, consider taking measures to improve the situation. The oxygen compensation device is a possible solution, but it also consumes oxygen. Therefore, it is necessary to comprehensively evaluate the changes in oxygen concentration after the oxygen compensation device is activated and the changes in oxygen concentration in the current area to determine whether the activation of the oxygen compensation device can affect the health and safety of individuals in the target area.

[0113] Specifically, the control unit is used to determine whether to activate the oxygen compensation device based on the reduction amount of the current oxygen concentration in the target area, including:

[0114] If the reduction in oxygen concentration in the current target area is greater than or equal to a preset oxygen concentration consumption threshold, determining to activate the oxygen compensation device;

[0115] If the reduction amount of the oxygen concentration in the current target area is less than the preset oxygen concentration consumption threshold, it is determined not to enable the oxygen compensation device.

[0116] Specifically, it also includes a display, which is connected to the monitor and is used to display the data monitored by the monitor.

[0117] Specifically, the display is connected to the monitor and can display the data monitored by the monitor in real time. This is crucial for the operation and management of the oxygen-rich sleep pillow. Preferably, the user can understand the key parameters such as the heart rate, blood pressure of the target object, and the oxygen concentration in the target object area at any time through the display. In practical applications, the operator can intuitively see the current state of the system, discover abnormal situations in a timely manner, and take corresponding measures.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
