Description

Technical Field

[0001] The present invention relates to the technical field of oxygen concentration monitoring, and in particular to an oxygen concentration monitor and a monitoring method thereof. Background Art

[0002] Hypoxia is a very common pathological and physiological phenomenon in clinical practice. Hypoxia can occur in almost all respiratory diseases and heart diseases. When a patient is hypoxic, oxygen is administered clinically through nasal cannula, mask, etc., which is commonly known as oxygen therapy. Oxygen therapy can increase blood oxygen saturation, increase oxygen partial pressure in the blood, and improve the hypoxic state of local tissues. It is a very practical and important issue to observe whether oxygen therapy is effective through an oxygen concentration monitor. Therefore, an oxygen concentration monitor and its monitoring method are needed.

[0003] The existing technology lacks a monitoring method that comprehensively considers performance monitoring, calibration, environmental factors and sampling frequency, which may lead to a decrease in the accuracy and reliability of the monitor, affecting the accurate monitoring and diagnosis of the patient's health status. Obviously, this monitoring method has at least the following problems: 1. The existing technology lacks monitoring and analysis of performance attenuation parameters, and the performance degradation of the monitor may not be detected and processed in time. This may cause the monitor to be in a state of low accuracy for a long time, affecting the accurate monitoring of the patient's health status. At the same time, there is no clear calibration judgment standard and analysis of calibration adjustment values, which may lead to accuracy problems of the monitor. The monitor may accumulate errors due to long-term non-calibration, which ultimately leads to inaccurate monitoring results.

[0004] 2. The existing technology lacks monitoring methods that take environmental factors into consideration. The monitor may be overly sensitive or insensitive to changes in the environment, resulting in deviations in monitoring results. For example, under different temperature, humidity and air pressure conditions, the monitor may show different accuracy and stability. At the same time, it is difficult to optimize the sampling frequency according to the patient's condition and environmental factors, which may lead to redundancy or omission of the monitor's sampling data. This will affect the efficiency and accuracy of monitoring and may lead to omissions or misjudgments of the patient's health status. Summary of the invention

[0017] A2. Compare the body mass assessment coefficient corresponding to the monitored patient in the target oxygen concentration monitor with the body mass assessment coefficients corresponding to each sampling frequency in the sampling frequency set of the monitored patient. If the body mass assessment coefficient corresponding to the monitored patient in the target oxygen concentration monitor is the same as the body mass assessment coefficient corresponding to a certain sampling frequency in the sampling frequency set of the monitored patient, then the sampling frequency in the sampling frequency set of the monitored patient will be used as the sampling frequency corresponding to the monitored patient in the target oxygen concentration monitor.

[0018] Preferably, the analysis obtains the environmental assessment coefficient corresponding to the target oxygen concentration monitor at each acquisition time point. The specific analysis process is as follows: the temperature, humidity and air pressure corresponding to the target oxygen concentration monitor at each acquisition time point are recorded as qi, yi and pi respectively, where i represents the number corresponding to each acquisition time point, i=1,2......n, n is any integer greater than 2, and is substituted into the calculation formula The environmental assessment coefficient γ corresponding to the target oxygen concentration monitor at the i-th acquisition time point is obtained i , where q′, y′, and p′ are the standard temperature, standard humidity, and standard air pressure corresponding to the set oxygen concentration monitor, respectively; τ1, τ2, and τ3 are the weight factors corresponding to the set oxygen concentration monitor temperature, humidity, and air pressure, respectively; Δq, Δy, and Δp are the set allowable oxygen concentration monitor temperature difference, allowable oxygen concentration monitor humidity difference, and allowable oxygen concentration monitor air pressure difference, respectively.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiments of the present invention Figure 1 As shown, the oxygen concentration monitor monitoring method includes: step one, obtaining performance attenuation parameters: obtaining the performance attenuation parameters corresponding to the target oxygen concentration monitor, the performance attenuation parameters including accuracy, response time, slope value and intercept value, thereby analyzing the performance attenuation parameters corresponding to the target oxygen concentration monitor to obtain the performance attenuation evaluation coefficient corresponding to the target oxygen concentration monitor.

[0030] It should be noted that, through experimental tests, the performance of the target oxygen concentration monitor is evaluated under various conditions: Accuracy: the accuracy is evaluated by comparing the difference between the oxygen concentration value output by the monitor and the actual oxygen concentration value; Response time: the response time is evaluated by analyzing the time required for the monitor to generate an output signal from receiving an input signal; Slope value and intercept value: the slope value and intercept value of the best fit line are found by fitting the data output by the monitor.

[0031] In a specific embodiment, the performance attenuation parameters corresponding to the target oxygen concentration monitor are analyzed, and the specific analysis process is as follows: the accuracy, response time, slope value and intercept value corresponding to the target oxygen concentration monitor are recorded as z, x, c and v respectively, and substituted into the calculation formula The performance attenuation evaluation coefficient corresponding to the target oxygen concentration monitor is obtained Among them, z′, x′, c′, and v′ are the standard accuracy, standard response time, standard slope value, and standard intercept value corresponding to the set oxygen concentration monitor, respectively; σ1, σ2, σ3, and σ4 are the weight factors corresponding to the accuracy of the set oxygen concentration monitor, the weight factors corresponding to the response time, the weight factors corresponding to the slope value, and the weight factors corresponding to the intercept value, respectively.

[0032] It should be noted that the target oxygen concentration monitor needs to achieve the required accuracy level in actual applications, the maximum time required for the monitor to generate an output signal after receiving an input signal, and the standard slope and intercept values ​​of the linear relationship of the monitor's output data are set. The standard accuracy, standard response time, standard slope value, and standard intercept value corresponding to the oxygen concentration monitor can be discussed and confirmed with technical experts, users, and relevant standard organizations based on actual application needs and performance requirements.

[0033] It should also be noted that according to the importance of accuracy, response time, slope value and intercept value in the monitor performance, corresponding weight factors are set, and through actual testing and verification, the weight factors corresponding to the accuracy, response time, slope value and intercept value of the oxygen concentration monitor are obtained to ensure that the performance of the monitor can meet actual needs.

[0034] It should be noted once again that σ1, σ2, σ3, and σ4 are all greater than 0 and less than 1.

[0035] Step 2. Determine the calibration status: Determine whether the target oxygen concentration monitor needs to be calibrated based on the performance attenuation evaluation coefficient corresponding to the target oxygen concentration monitor. If it is determined that the target oxygen concentration monitor needs to be calibrated, analyze the calibration adjustment value corresponding to the target oxygen concentration monitor, and adjust the target oxygen concentration monitor according to the corresponding calibration adjustment value.

[0036] In a specific embodiment, the determination of whether the target oxygen concentration monitor needs to be calibrated is carried out as follows: the performance attenuation assessment coefficient corresponding to the target oxygen concentration monitor is compared with the performance attenuation assessment coefficient corresponding to a set standard oxygen concentration monitor. If the performance attenuation assessment coefficient corresponding to the target oxygen concentration monitor is smaller than the performance attenuation assessment coefficient corresponding to the set standard oxygen concentration monitor, it is determined that the target oxygen concentration monitor needs to be calibrated. If the performance attenuation assessment coefficient corresponding to the target oxygen concentration monitor is greater than or equal to the performance attenuation assessment coefficient corresponding to the set standard oxygen concentration monitor, it is determined that the target oxygen concentration monitor does not need to be calibrated.

[0037] In another specific embodiment, the calibration adjustment value corresponding to the target oxygen concentration monitor is analyzed, and the specific analysis process is as follows: a performance attenuation assessment coefficient corresponding to the target oxygen concentration monitor is differentially calculated with a performance attenuation assessment coefficient corresponding to a set standard oxygen concentration monitor to obtain a difference between the performance attenuation assessment coefficient corresponding to the target oxygen concentration monitor and the performance attenuation assessment coefficient corresponding to the set standard oxygen concentration monitor, and the difference is compared with the calibration adjustment value corresponding to each difference in a database; if the difference is the same as a calibration adjustment value corresponding to a certain difference in the database, the calibration adjustment value corresponding to the difference in the database is used as the calibration adjustment value corresponding to the target oxygen concentration monitor.

[0038] Step 3. Obtaining the body mass index: When the target oxygen concentration monitor is running, the body mass index corresponding to the patient monitored in the target oxygen concentration monitor is obtained. The body mass index includes blood oxygen saturation, respiratory rate and heart rate, and then the body mass assessment coefficient corresponding to the patient monitored in the target oxygen concentration monitor is obtained by analysis.

[0039] It should be noted that the blood oxygen saturation, respiratory rate and heart rate corresponding to the target oxygen concentration monitor are obtained by using sensors and monitoring equipment.

[0040] In a specific embodiment, the analysis obtains the body mass assessment coefficient corresponding to the patient monitored in the target oxygen concentration monitor. The specific analysis process is as follows: the blood oxygen saturation, respiratory rate and heart rate corresponding to the patient monitored in the target oxygen concentration monitor are recorded as f, g and h respectively, and substituted into the calculation formula The body mass assessment coefficient φ corresponding to the monitored patient in the target oxygen concentration monitor is obtained, where f′, g′, and h′ are the standard blood oxygen saturation, standard respiratory rate, and standard heart rate corresponding to the set monitored patient, respectively. They are respectively the weight factors corresponding to the patient's blood oxygen saturation, the weight factors corresponding to the respiratory rate, and the weight factors corresponding to the heart rate.

[0041] It should be noted that Both are greater than 0 and less than 1.

[0042] It should also be noted that the process of standardizing blood oxygen saturation, standard respiratory rate, standard heart rate, and standard parameters should be based on the patient's actual situation and health needs, and determined by medical experts, nurses, and reference to medical literature or clinical guidelines. First, it is necessary to determine the importance of each indicator in physical health assessment, and discuss and exchange opinions on the importance of each indicator with medical experts, nurses and other professionals to obtain professional advice and guidance, as well as refer to relevant literature and research to understand the importance and impact of different indicators in physical health assessment, so as to set the weight factors corresponding to monitoring the patient's blood oxygen saturation, respiratory rate, and heart rate.

[0043] Step 4. Setting the sampling frequency: Obtain the age and disease severity of the patient monitored in the target oxygen concentration monitor, and then analyze and set the sampling frequency corresponding to the patient monitored in the target oxygen concentration monitor based on the age, disease severity and body mass assessment coefficient of the patient monitored in the target oxygen concentration monitor.

[0044] In a specific embodiment, the sampling frequency corresponding to the patient monitored in the target oxygen concentration monitor is analyzed, and the specific analysis process is as follows: A1. Compare the age and disease severity corresponding to the patient monitored in the target oxygen concentration monitor with the age and disease severity corresponding to each sampling frequency set in the database. If the age and disease severity corresponding to the patient monitored in the target oxygen concentration monitor are the same as the age and disease severity corresponding to a sampling frequency set in the database, then use the sampling frequency set in the database as the sampling frequency set corresponding to the patient monitored in the target oxygen concentration monitor.

[0045] A2. Compare the body mass assessment coefficient corresponding to the monitored patient in the target oxygen concentration monitor with the body mass assessment coefficients corresponding to each sampling frequency in the sampling frequency set of the monitored patient. If the body mass assessment coefficient corresponding to the monitored patient in the target oxygen concentration monitor is the same as the body mass assessment coefficient corresponding to a certain sampling frequency in the sampling frequency set of the monitored patient, then the sampling frequency in the sampling frequency set of the monitored patient will be used as the sampling frequency corresponding to the monitored patient in the target oxygen concentration monitor.

[0046] It should be noted that doctors will evaluate patients during the diagnosis and treatment process. Doctors can evaluate patients based on their condition, signs, symptoms, etc. to determine the severity of their condition. Doctors will also learn about the age of patients.

[0047] In the embodiment of the present invention, the performance status of the target oxygen concentration monitor can be monitored in real time by acquiring and analyzing the performance attenuation parameters. This helps to adjust the performance of the monitor in a timely manner to ensure its accuracy and stability, thereby improving the performance and service quality of the monitor. Based on the performance attenuation evaluation coefficient, it can be accurately determined whether the monitor needs to be calibrated, avoiding unnecessary calibration or ignoring the actual need for calibration. In this way, the accuracy and efficiency of the calibration can be improved, the accuracy and reliability of the monitor can be ensured, and the efficiency of the monitor can be improved through precise performance adjustment and calibration judgment, as well as personalized monitoring services, and unnecessary maintenance costs and manpower input can be reduced. This helps to improve the efficiency and quality of medical services while saving medical resources.

[0048] Step 5. Obtaining the environmental assessment coefficient: When the target oxygen concentration monitor is running, set several collection time points to collect the environmental data corresponding to the target oxygen concentration monitor at each collection time point. The environmental data includes temperature, humidity and air pressure, and then analyze to obtain the environmental assessment coefficient corresponding to the target oxygen concentration monitor at each collection time point.

[0049] It should be noted that special environmental sensors are used to obtain data such as temperature, humidity and air pressure. These sensors are directly installed near the target oxygen concentration monitor or integrated into the monitor to monitor environmental parameters in real time.

[0050] In a specific embodiment, the analysis obtains the environmental assessment coefficient corresponding to the target oxygen concentration monitor at each acquisition time point. The specific analysis process is as follows: the temperature, humidity and air pressure corresponding to the target oxygen concentration monitor at each acquisition time point are recorded as qi, yi and pi respectively, where i represents the number corresponding to each acquisition time point, i=1,2......n, n is any integer greater than 2, and is substituted into the calculation formula The environmental assessment coefficient γ corresponding to the target oxygen concentration monitor at the i-th acquisition time point is obtained i , where q′, y′, and p′ are the standard temperature, standard humidity, and standard air pressure corresponding to the set oxygen concentration monitor, respectively; τ1, τ2, and τ3 are the weight factors corresponding to the set oxygen concentration monitor temperature, humidity, and air pressure, respectively; Δq, Δy, and Δp are the set allowable oxygen concentration monitor temperature difference, allowable oxygen concentration monitor humidity difference, and allowable oxygen concentration monitor air pressure difference, respectively.

[0051] Step 6. Selection of compensation algorithm: According to the environmental assessment coefficient corresponding to the target oxygen concentration monitor at each acquisition time point, the compensation algorithm corresponding to the target oxygen concentration monitor at each acquisition time point is analyzed, and the target oxygen concentration monitor at each acquisition time point is adjusted according to the corresponding compensation algorithm.

[0052] It should be noted that the compensation algorithm is used to correct or adjust the reading of the target oxygen concentration monitor to eliminate the interference of environmental factors on the oxygen concentration measurement. The compensation algorithm includes temperature compensation, humidity compensation and air pressure compensation.

[0053] It is also necessary to explain that temperature compensation: the effect of temperature on oxygen concentration is common, so the reading of the target oxygen concentration monitor can be compensated according to the change in temperature. For example, if the temperature rises, the reading can be reduced according to the temperature coefficient to reduce the effect of temperature on oxygen concentration. Humidity compensation: Humidity can also affect the reading of the oxygen concentration monitor, especially in an environment with high humidity. The reading can be adjusted according to the humidity coefficient to eliminate the interference of humidity on oxygen concentration. Barometric pressure compensation: Changes in barometric pressure may also affect the measurement of oxygen concentration, especially in high altitude or low pressure environments. The reading can be compensated according to the barometric pressure coefficient to correct the effect of barometric pressure on oxygen concentration.

[0054] In a specific embodiment, the compensation algorithm corresponding to the target oxygen concentration monitor at each acquisition time point is analyzed, and the specific analysis process is as follows: the environmental assessment coefficient corresponding to the target oxygen concentration monitor at each acquisition time point is compared with the environmental assessment coefficient corresponding to each compensation algorithm in the database. If the environmental assessment coefficient corresponding to the target oxygen concentration monitor at a certain acquisition time point is the same as the environmental assessment coefficient corresponding to a compensation algorithm in the database, then the compensation algorithm in the database is used as the compensation algorithm corresponding to the target oxygen concentration monitor at the acquisition time point. In this way, the compensation algorithm corresponding to the target oxygen concentration monitor at each acquisition time point is analyzed.

[0055] The embodiment of the present invention can improve the adaptability of the monitor to environmental changes by considering environmental factors and selecting appropriate compensation algorithms. This helps to reduce the impact of environmental factors on monitoring results, improve the stability and accuracy of monitoring data, and personalize monitoring services by obtaining the patient's body mass index and environmental assessment coefficient. The sampling frequency and compensation algorithm of the monitor are adjusted to more accurately monitor the patient's physiological parameters.

[0056] Embodiments of the present invention Figure 2As shown, the oxygen concentration monitor includes an oxygen concentration monitor 1, a low oxygen concentration alarm switch 2 is electrically installed on the upper side of the outer surface of the oxygen concentration monitor 1, and an excessively high oxygen concentration alarm switch 4 is electrically installed on the lower side of the outer surface of the oxygen concentration monitor 1, and the low oxygen concentration alarm switch 2 is symmetrical with the excessively high oxygen concentration alarm switch 4, a low oxygen concentration alarm light 3 and an excessively high oxygen concentration alarm light 5 are electrically installed between the low oxygen concentration alarm switch 2 and the excessively high oxygen concentration alarm switch 4, and the low oxygen concentration alarm light 3 is close to the low oxygen concentration alarm switch 2, and the excessively high oxygen concentration alarm light 5 is close to the excessively high oxygen concentration alarm switch 4, a spring shaft 6 is rotatably installed on the central axis of the oxygen concentration monitor 1, and a pipeline clamp 7 is opened on one side of the oxygen concentration monitor 1.

[0057] The present invention provides an oxygen concentration monitor and a monitoring method thereof, which effectively improves the accuracy and reliability of the monitor through comprehensive performance parameter acquisition, calibration judgment, body mass index analysis, sampling frequency setting, environmental assessment and compensation algorithm selection. This method can not only optimize the physical condition assessment of the monitored patient, but also provide more accurate monitoring data according to the environmental conditions, thereby better meeting clinical needs, providing reliable monitoring services, and further improving the quality of medical care.
