[0002] With the aggravation of population aging and the increase in the number of patients with chronic diseases, the need for health monitoring of people with limited mobility is becoming increasingly urgent.

[0003] Traditional health monitoring devices often have a single function, unable to simultaneously monitor respiratory and vital sign parameters, and lack an intelligent abnormal judgment and early warning mechanism, resulting in a high false alarm rate and untimely response. Especially in the elderly population with a high incidence of respiratory function abnormalities and cardiovascular diseases, real-time and accurate health monitoring is particularly important. Existing intelligent wheelchairs, although having basic mobility functions, lack an integrated health detection system and cannot meet the health management needs of users.

[0064] It is understandable that the present invention can comprehensively evaluate the user's health status by collecting modules to monitor the user's breathing parameters (breathing frequency, tidal volume) and vital sign parameters (heart rate, blood oxygen saturation) in real time. The processing module adopts a multi-level abnormal judgment mechanism, first identifying abnormalities through preliminary judgment and then calculating abnormal values in combination with change values, improving the accuracy and reliability of detection. This dual judgment mechanism can effectively reduce false alarms and missed alarms, ensuring timely detection of breathing and vital sign abnormalities. The alarm module gives graded alarms according to the level of abnormal values and provides more accurate warning information in combination with the comprehensive alarm level of breathing and vital signs. This system is particularly suitable for users with limited mobility or poor breathing function, such as the elderly, postoperative patients, or patients with chronic respiratory diseases, and can help them grasp their own health status in real time, reduce the risk of sudden health problems, and improve the quality of life. In addition, the intelligent and automated design of the system reduces the burden on nursing staff and provides efficient technical support for medical care.

[0065] Specifically, the ventilator is set on the wheelchair so that the user can continuously breathe with the ventilator when traveling in the wheelchair.

[0066] In some embodiments of the present application, when the processing module is configured to preliminarily judge whether the user's breathing is abnormal according to the breathing parameters, it includes:

[0067] Preset a standard range for breathing frequency and a standard range for tidal volume;

[0068] If the breathing frequency is not within the standard range of breathing frequency and / or the tidal volume is not within the standard range of tidal volume, the preliminary judgment result is that an abnormality has occurred;

[0069] If the breathing frequency is within the standard range of breathing frequency and the tidal volume is within the standard range of tidal volume, the preliminary judgment result is that no abnormality has occurred.

[0070] In some embodiments of the present application, when the processing module is configured to calculate a first abnormal value if the preliminary judgment result is that an abnormality has occurred, it includes:

[0071] Calculate the absolute value of the frequency difference between the breathing frequency and the standard range of breathing frequency, and calculate the absolute value of the tidal difference between the tidal volume and the standard range of tidal volume; wherein, if the breathing frequency is within the standard range of breathing frequency, the absolute value of the frequency difference is recorded as 0; if the tidal volume is within the standard range of tidal volume, the absolute value of the tidal difference is recorded as 0;

[0072] Calculate the first abnormal value through the following formula:

[0073]

[0074] In the above formula, S1 represents the first outlier, ΔP represents the absolute value of the frequency difference, Pmax represents the maximum value of the standard range of the respiratory rate, Pmin represents the minimum value of the standard range of the respiratory rate, ΔC represents the absolute value of the tidal volume difference, Cmax represents the maximum value of the standard range of the tidal volume, and Cmin represents the minimum value of the standard range of the tidal volume.

[0075] In some embodiments of the present application, when the processing module is configured to collect the respiratory change value of the respiratory parameter and calculate the second outlier according to the respiratory change value, it includes:

[0076] Collect the respiratory rate change value and the tidal volume change value within a preset time;

[0077] Set the respiratory rate safety fluctuation value and the tidal volume safety fluctuation value, and calculate the second outlier according to the following formula:

[0078]

[0079] In the above formula, S2 represents the second outlier, ΔPb represents the respiratory rate change value, ΔCb represents the tidal volume change value, Pd represents the respiratory rate safety fluctuation value, and Cd represents the tidal volume safety fluctuation value;

[0080] Wherein, the respiratory rate change value is the absolute value of the difference between the initial respiratory rate and the final respiratory rate within a preset time, and the tidal volume change value is the absolute value of the difference between the initial tidal volume and the final tidal volume within a preset time.

[0081] In some embodiments of the present application, when the processing module is configured to obtain the respiratory outlier according to the first outlier and the second outlier, it includes:

[0082] Calculate the respiratory outlier through the following formula:

[0083] Sh = S1 * a + S2 * b;

[0084] In the above formula, Sh represents the respiratory outlier, S1 represents the first outlier, S2 represents the second outlier, a and b represent weights, and a + b = 1.

[0085] It can be understood that in the embodiments of the present application, the processing module determines whether the user's breathing is abnormal through a series of steps. First, it sets the standard ranges of breathing rate and tidal volume. If the user's breathing rate or tidal volume exceeds these ranges, the system will initially determine it as abnormal. Conversely, if both are within the standard ranges, the breathing is considered normal. Further, if the initial determination is abnormal, the system calculates a first abnormal value based on the deviation of the breathing rate and tidal volume from their respective standard ranges. In addition, the system also monitors the change values of the breathing parameters and calculates a second abnormal value based on this, which reflects the fluctuations of the breathing rate and tidal volume within a preset time. Finally, the system combines the first abnormal value and the second abnormal value and obtains a comprehensive breathing abnormal value through weighted calculation, so as to more accurately evaluate the user's breathing condition. This method not only considers the static breathing parameter standards but also the changes of breathing parameters over time, providing a comprehensive breathing health assessment for the user.

[0086] In some embodiments of the present application, when the processing module is further configured to initially determine whether the user's vital signs are abnormal according to the vital sign parameters, it includes:

[0087] Preset the standard ranges of heart rate and blood oxygen saturation;

[0088] If the heart rate is not within the standard range of the heart rate and / or the blood oxygen saturation is not within the standard range of the blood oxygen saturation, the initial judgment result is abnormal;

[0089] If the heart rate is within the standard range of the heart rate and the blood oxygen saturation is within the standard range of the blood oxygen saturation, the initial judgment result is not abnormal.

[0090] In some embodiments of the present application, when the processing module is further configured to calculate a third abnormal value if the initial judgment result is abnormal, it includes:

[0091] Calculate the absolute value of the heart rate difference between the heart rate and the standard range of the heart rate, and calculate the absolute value of the blood oxygen difference between the blood oxygen saturation and the standard range of the blood oxygen saturation; wherein, if the heart rate is within the standard range of the heart rate, the absolute value of the heart rate difference is recorded as 0; if the blood oxygen saturation is within the standard range of the blood oxygen saturation, the absolute value of the blood oxygen difference is recorded as 0;

[0092] Calculate the third abnormal value through the following formula:

[0093]

[0094] In the above formula, S3 represents the third outlier, ΔX represents the absolute value of the heart rate difference, Xmax represents the maximum value of the heart rate standard range, Xmin represents the minimum value of the heart rate standard range, ΔY represents the absolute value of the blood oxygen difference, Ymax represents the maximum value of the blood oxygen saturation standard range, and Ymin represents the minimum value of the blood oxygen saturation standard range.

[0095] In some embodiments of the present application, when the processing module is further configured to collect the sign change values of the vital sign parameters and calculate the fourth outlier according to the sign change values, it includes:

[0096] Collect the heart rate change value and the blood oxygen saturation change value within a preset time;

[0097] Set the heart rate safety fluctuation value and the blood oxygen saturation safety fluctuation value, and calculate the fourth outlier according to the following formula:

[0098]

[0099] In the above formula, S4 represents the fourth outlier, ΔXb represents the heart rate change value, ΔYb represents the blood oxygen saturation change value, Xd represents the heart rate safety fluctuation value, and Yd represents the blood oxygen saturation safety fluctuation value;

[0100] Wherein, the heart rate change value is the absolute value of the difference between the initial heart rate and the final heart rate within a preset time, and the blood oxygen saturation change value is the absolute value of the difference between the initial blood oxygen saturation and the final blood oxygen saturation within a preset time.

[0101] In some embodiments of the present application, when the processing module is further configured to obtain the sign outlier according to the third outlier and the fourth outlier, it includes:

[0102] Calculate the sign outlier through the following formula:

[0103] St = S3 * c + S4 * d;

[0104] In the above formula, St represents the sign outlier, S3 represents the third outlier, S4 represents the fourth outlier, c and d represent weights, and c + d = 1.

[0105] It can be understood that in the embodiments of the present application, the processing module preliminarily determines whether the user's vital signs are abnormal through a series of preset standard ranges of heart rate and blood oxygen saturation. When the heart rate or blood oxygen saturation exceeds these ranges, the system will preliminarily determine it as abnormal. In addition, the system can also calculate a third abnormal value and a fourth abnormal value, respectively based on the deviation of the heart rate and blood oxygen saturation from their respective standard ranges and the change value of the vital signs within a preset time. The third abnormal value is calculated based on the relationship between the absolute value of the difference between the heart rate and blood oxygen saturation and the maximum and minimum values of their respective standard ranges, while the fourth abnormal value is calculated based on the relationship between the change value of the heart rate and blood oxygen saturation within a preset time and their respective safe fluctuation values. Finally, by combining the third abnormal value and the fourth abnormal value and assigning corresponding weights, the system can obtain a comprehensive vital sign abnormal value, thereby providing a more comprehensive evaluation of the user's vital sign abnormalities. This method can not only detect abnormal vital signs in a timely manner but also provide more accurate and personalized health monitoring results through comprehensive analysis of the changes in different parameters.

[0106] In some embodiments of the present application, the alarm module is configured to perform hierarchical alarms respectively according to the respiratory abnormal value and the vital sign abnormal value, and when performing a comprehensive alarm according to the alarm levels of the two hierarchical alarms, it includes:

[0107] Set a first respiratory abnormal value and a second respiratory abnormal value, where the first respiratory abnormal value is less than the second respiratory abnormal value;

[0108] If the respiratory abnormal value is less than the first respiratory abnormal value, a first-level respiratory abnormal alarm is performed; if the respiratory abnormal value is greater than or equal to the first respiratory abnormal value and less than or equal to the second respiratory abnormal value, a second-level respiratory abnormal alarm is performed; if the respiratory abnormal value is greater than the second respiratory abnormal value, a third-level respiratory abnormal alarm is performed; where the respiratory abnormal alarm levels are, from low to high, the first-level respiratory abnormal alarm, the second-level respiratory abnormal alarm, and the third-level respiratory abnormal alarm;

[0109] Set a first vital sign abnormal value and a second vital sign abnormal value, where the first vital sign abnormal value is less than the second vital sign abnormal value;

[0110] If the vital sign abnormal value is less than the first vital sign abnormal value, a first-level vital sign abnormal alarm is performed; if the vital sign abnormal value is greater than or equal to the first vital sign abnormal value and less than or equal to the second vital sign abnormal value, a second-level vital sign abnormal alarm is performed; if the vital sign abnormal value is greater than the second vital sign abnormal value, a third-level vital sign abnormal alarm is performed; where the vital sign abnormal alarm levels are, from low to high, the first-level vital sign abnormal alarm, the second-level vital sign abnormal alarm, and the third-level vital sign abnormal alarm;

[0111] If both the respiratory abnormality alarm level and the physical sign abnormality alarm level are higher than or equal to level two, a comprehensive alarm is issued.

[0112] It can be understood that in some embodiments of the present application, the alarm module realizes a hierarchical alarm mechanism by setting different thresholds for respiratory and physical sign abnormalities, thereby improving the accuracy and pertinence of the alarm. Specifically, by setting the first and second respiratory abnormality values and the first and second physical sign abnormality values, the system can issue respiratory abnormality alarms and physical sign abnormality alarms of level one, level two, or level three respectively according to the severity of the abnormality values. This hierarchical alarm method can not only timely remind medical staff to pay attention to the patient's condition, but also take corresponding emergency measures according to the severity of the abnormality. In addition, when both the respiratory abnormality alarm level and the physical sign abnormality alarm level reach or exceed level two, the system will trigger a comprehensive alarm, which ensures that when the patient has multiple health problems, joint response measures can be quickly taken, thereby improving the treatment effect and safety of the patient. Generally speaking, this hierarchical and comprehensive alarm mechanism helps to improve the response efficiency and accuracy of the medical monitoring system and provide more considerate and timely medical services for the patient.
