Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of blood oximeters and related technical fields, and in particular, to a blood oximeter adjustment method and device. Background Art

[0002] As a portable medical device, users can use the oximeter to monitor their health status, including heart rate and blood oxygen, anytime and anywhere. There are two measurement methods of the oximeter: reflection and transmission.

[0003] Among them, the measurement principle of the transmission oximeter is as follows: there is a light-emitting LED on one side of the finger, and a photodiode on the other side (used to detect light intensity and convert light into current. The stronger the light, the greater the current). Human fingers (including skin, bones, and blood) absorb light, and blood absorbs more light than other tissues. During the flow of blood, due to the periodic beating of the heart, the blood presents a pulsating form, that is, a pulse. This will cause the absorbed light to be different, and the feedback to the photodiode will present a changing photocurrent. When the sampling frequency is high enough, a complete and continuous pulse waveform will be presented. The heart rate is calculated by counting the number of continuous pulse waveforms and calculating the number of waveforms per minute, that is, the number of heartbeats. The oxygen inhaled through breathing will combine with hemoglobin in the blood to form oxygenated hemoglobin. Hemoglobin has a higher absorption coefficient for red light, and oxygenated hemoglobin has a higher absorption coefficient for infrared light; the blood oxygen result can be calculated by detecting oxygenated hemoglobin and hemoglobin using red light and infrared light respectively.

[0004] The current mainstream blood oximeters have problems during use due to the thickness of human fingers, skin color, and environmental factors, resulting in a narrow application range and inaccurate test results. Summary of the invention

[0063] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0064] Based on the problems existing in the existing technology, Figure 1 is a flow chart of a blood oximeter adjustment method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the specific process of the blood oximeter adjustment method includes:

[0065] S110, acquiring light intensity data corresponding to the target finger to form a light intensity data group.

[0066] Specifically, the light intensity data group includes a plurality of light intensity data, and the light intensity data is light intensity data passing through the target finger detected by the light receiving component of the oximeter.

[0067] In a specific implementation, firstly, after the target finger is placed on the oximeter, the photodiode of the oximeter detects the light intensity data passing through the target finger.

[0068] One possible way to obtain the light intensity data corresponding to the target finger and form a light intensity data group includes: obtaining the light intensity data corresponding to the target finger and sequentially forming a light intensity data group whose state information is a target preset threshold.

[0069] Specifically, the target preset threshold is set to include at least a first target preset threshold and a second target preset threshold, and by continuously acquiring light intensity data corresponding to the target finger, a first light intensity data group of the first target preset threshold and a second light intensity data group of the second target preset threshold are sequentially formed.

[0070] Exemplarily, the first target preset threshold is 100, and the second target preset threshold is 30. By acquiring the light intensity data corresponding to the target finger and dividing the collected light intensity data of the target finger, a first light intensity data group whose state information is the first target preset threshold is formed in sequence, and a light intensity data group whose state information is the second target preset threshold is formed in sequence. For example, if the collected light intensity data corresponding to the target finger is 150, then the light intensity data 1-100 form a first light intensity data group. Since the number of data of the remaining light intensity data 101-150 does not meet the first preset threshold, the remaining light intensity data 101-150 do not form a first light intensity data group. In addition, the light intensity data 1-30 can also form a second light intensity data group, 31-60 form a second light intensity data group, 61-90 form a second light intensity data group, 91-120 form a second light intensity data group, and 121-150 form a second light intensity data group.

[0071] S120. Calculate parameter information corresponding to the light intensity data group according to the state information corresponding to the light intensity data group.

[0072] The state information includes the number of light intensity data included in the light intensity data group and / or the time of collecting the light intensity data group, and the parameter information includes the perfusion index and / or the average light intensity.

[0073] Perfusion Index (PI), PI value reflects the pulsating blood flow, that is, reflects the blood perfusion capacity. The greater the pulsating blood flow, the more pulsating components, and the greater the PI value. Therefore, the measurement site (skin, nails, bones, etc.) and the patient's own blood perfusion (arterial blood flow) will affect the PI value. Since the sympathetic nerves affect heart rate and arterial blood pressure (affecting pulsating arterial blood flow), the human body's neural regulation system or mental state will also indirectly affect the PI value.

[0074] The average light intensity is the average value of the light intensity passing through the target finger detected by the photodiode of the oximeter. The average light intensity indirectly reflects the blood flow status of the human body.

[0075] As an implementable method, parameter information corresponding to the light intensity data group is determined according to state information corresponding to the light intensity data group, including: configuring a pre-associated adjustment parameter type according to a target preset threshold, and calculating parameter information corresponding to the adjustment parameter type based on the acquired light intensity data group.

[0076] Specifically, the adjustment parameter type is determined to be the perfusion index according to the first target preset threshold, and the corresponding first perfusion index is calculated according to the first light intensity data group; the adjustment parameter type is determined to be the average light intensity according to the second target preset threshold, and the corresponding first average light intensity is calculated according to the second light intensity data group.

[0077] Exemplarily, when the number of light intensity data included in the first light intensity data group is 100 light intensity data, the corresponding first perfusion index is calculated based on the first light intensity data group, and when the number of light intensity data included in the second light intensity data group is 30 light intensity data, the corresponding first average light intensity is calculated based on the second light intensity data group.

[0078] The first perfusion index is calculated as follows: first, the average value DC corresponding to the 100 light intensity data included in the first light intensity data group is calculated, and then the difference AC corresponding to the maximum light intensity value and the minimum light intensity value corresponding to the 100 light intensity data included in the first light intensity data group is calculated, and the first perfusion index is determined by multiplying the average value DC with the difference AC between the maximum light intensity value and the minimum light intensity value. The first average light intensity is calculated as follows: the average value DC corresponding to the 30 light intensity data included in the second light intensity data group is calculated.

[0079] In this embodiment, when the number of acquired light intensity data does not meet the first target preset threshold value, but meets the second target preset threshold value, at this time, by acquiring the first average light intensity corresponding to 30 light intensity data in the light intensity data group, it is possible to adjust the current gear according to the user's finger situation and then adjust the light intensity of the light-transmitting fingers, such as bright fingers (thin fingers are easy to transmit light) and dark fingers (fat fingers are not easy to transmit light), thereby reducing the time for adjusting to the appropriate light intensity and improving the accuracy of the oximeter measurement results. As the acquired light intensity data increases, when the number of light intensity data meets the first target preset threshold value, at this time, the first perfusion index corresponding to the light intensity data is calculated, and then the current gear of the oximeter is adjusted according to the first perfusion index, that is, according to the perfusion index, the current gear of the oximeter is adjusted to eliminate the influence of the human body's own environment on the accuracy of the oximeter measurement results, thereby improving the accuracy of the oximeter.

[0080] As another implementable method, parameter information corresponding to the light intensity data group is determined based on status information corresponding to the light intensity data group, including: when the acquired status information of the light intensity data group meets N times the target preset threshold, a pre-associated adjustment parameter type is configured according to the target preset threshold, and parameter information corresponding to the adjustment parameter type is calculated based on the most recently acquired sub-light intensity data group, wherein the light intensity data group includes N sub-light intensity data groups, the status information of each sub-light intensity data group is the target preset threshold, and N is an integer greater than or equal to 1.

[0081] Specifically, when the status information of the acquired light intensity data group meets A times the first target preset threshold, the adjustment parameter type is determined to be the perfusion index according to the first target preset threshold, and the corresponding second perfusion index is calculated according to the latest acquired sub-light intensity data group; when the status information of the acquired light intensity data group meets B times the second target preset threshold, the adjustment parameter type is determined to be the average light intensity according to the second target preset threshold, and the corresponding second average light intensity is calculated according to the latest acquired sub-light intensity data group.

[0082] In this embodiment, the first target preset threshold is 100, the second target preset threshold is 30, and a light intensity data group is formed by acquiring light intensity data corresponding to the target finger. When the status information of the acquired light intensity data group meets A times the first target preset threshold, for example, if the collected light intensity data corresponding to the target finger is 150, then the light intensity data group composed of light intensity data 1-100 meets 1 times the first target preset threshold. At this time, the sub-light intensity data group composed of the light intensity data corresponding to 1-100 has calculated the corresponding perfusion index, and as the light intensity data continues to increase, it increases to 200, that is, the status information of the light intensity data group meets 2 times the first target preset threshold. At this time, the second perfusion index corresponding to the sub-light intensity data group formed by the light intensity data 101-200 is calculated. If the number of light intensity data collected corresponding to the target finger is 150, light intensity data 1-30 form a second light intensity data group, 31-60 form a second light intensity data group, 61-90 form a second light intensity data group, 91-120 form a second light intensity data group, and 121-150 form a second light intensity data group. As the light intensity data continues to increase, it increases to 180, that is, the state information of the light intensity data group meets 6 times the second target preset threshold. At this time, the second average light intensity corresponding to the sub-light intensity data group formed by light intensity data 151-180 is calculated.

[0083] In the above embodiment, when the state parameter is the time for collecting light intensity data groups, at this time, the first target preset threshold is the time for one cycle of the pulse wave, and the second target preset threshold is less than the time for one cycle of the pulse wave; when the state parameter is the number of light intensity data groups collected, at this time, the second target preset threshold is less than the first target preset threshold.

[0084] Since the blood oximeter needs at least one pulse wave cycle (normally 60 / minute) to calculate the PI value, and when 100 light intensity data are obtained, the time corresponding to the acquisition of 100 light intensity data is exactly the time of one pulse wave cycle, therefore, the parameter information corresponding to the light intensity data group can be determined by the number of light intensity data groups collected or the time of collecting light intensity data groups.

[0085] S130: Adjust the light intensity of the light emitting component of the oximeter according to the parameter information.

[0086] As a specific implementable method, the current level of the oximeter is adjusted according to the relationship between the parameter information and the preset parameter information.

[0087] The preset parameter information includes a preset perfusion index and a preset average light intensity.

[0088] As a specific implementation, adjusting the current level of the oximeter according to the relationship between the parameter information and the preset parameter information includes: adjusting the current level of the oximeter according to the relationship between the perfusion index and the preset perfusion index.

[0089] Specifically: when the perfusion index is less than a first preset perfusion index, the current gear of the blood oximeter is increased; when the perfusion index is greater than a second preset perfusion index, the current gear of the blood oximeter is decreased.

[0090] The first preset perfusion index is 0.4, and the second preset perfusion index is 1, wherein 0.4 is a weak perfusion index and 1 is a strong perfusion index. Under this perfusion index, the blood oxygen value measurement results are inaccurate.

[0091] By calculating the perfusion index, the current gear of the oximeter is adjusted according to the perfusion index. Since the perfusion index can stably reflect the blood flow state of the human body and is less affected by the external environment, for example, when the human hands are cold, the blood flow at the fingertips decreases and the PI value is low. By calculating the PI value and adjusting the current gear of the oximeter, the inaccurate measurement results of the oximeter caused by the human body being affected by changes in the ambient temperature can be reduced.

[0092] As another specific implementation, adjusting the current level of the oximeter according to the relationship between the average light intensity and the preset average light intensity includes: adjusting the current level of the oximeter according to the relationship between the perfusion index and the preset perfusion index.

[0093] Specifically, when the average light intensity is less than the first preset average light intensity, the current gear of the oximeter is increased; when the average light intensity is greater than the second preset average light intensity, the current gear of the oximeter is reduced.

[0094] By calculating the average light intensity and adjusting the current gear of the oximeter according to the average light intensity, the influence of bright fingers (thin fingers are easy to transmit light) and dark fingers (fat fingers are not easy to transmit light) on the accuracy of the oximeter measurement results can be avoided. The influence of received light intensity on the accuracy of the oximeter measurement results can also be filtered out.

[0095] It should be noted that, in the above embodiment, in the process of increasing the current level of the oximeter or decreasing the current level of the oximeter, the value of the current level increased or decreased each time is one level.

[0096] It should be noted that in the disclosed embodiment, the current gear of the oximeter includes 5 gears. The current value of the first gear is: when there is no finger in the oximeter, the current value required for the maximum light intensity that the photodiode in the oximeter can receive, and this current is the minimum current. The current value of the fifth gear is, based on the big data collection of the thickness of multiple people's fingers, the thickest (dark finger) is put into the oximeter, and the current value required for the maximum light intensity that the photodiode can receive is the maximum current. The current values ​​of other gears are the equal parts of the maximum current and the minimum current.

[0097] The oximeter adjustment method provided by the embodiment of the present disclosure obtains light intensity data corresponding to a target finger to form a light intensity data group, wherein the light intensity data is light intensity data detected by a light receiving component of the oximeter and transmitted through the target finger; according to state information corresponding to the light intensity data group, parameter information corresponding to the light intensity data group is calculated; and according to the parameter information, the luminous intensity of the light emitting component of the oximeter is adjusted, wherein the parameter information corresponding to the calculated light intensity data group includes an average light intensity and a perfusion index, and the current gear of the oximeter is adjusted according to the average light intensity, so as to eliminate the influence of bright fingers, dark fingers and ambient light on the accuracy of the oximeter measurement result, and the current gear of the oximeter is adjusted according to the perfusion index, that is, according to the perfusion index, the current gear of the oximeter is adjusted to eliminate the influence of the human body's own environment on the accuracy of the oximeter measurement result, that is, the influence of the thickness of the human finger and the skin color on the accuracy of the oximeter measurement result can be eliminated, and the influence of environmental factors on the accuracy of the oximeter measurement result can also be eliminated. In the present invention, different adjustment parameter types are determined according to the state information of the light intensity data group; the efficiency of adjusting the light intensity is enhanced, so that the blood oximeter can output a stable value in a shorter time, and the blood oximeter outputs a value faster.

[0098] In a specific implementation, before obtaining the light intensity data corresponding to the target finger, the method further includes: adjusting the current gear of the oximeter to an initial gear, wherein the initial gear is a middle gear of the current gear of the oximeter.

[0099] Before obtaining the light intensity data corresponding to the target finger, first adjust the current gear of the oximeter to the initial gear, that is, the middle gear of the current gear, to ensure the accuracy of the light intensity data obtained later, reduce unnecessary adjustment of the current gear, and improve the efficiency of the oximeter in outputting stable values.

[0100] In addition, the oximeter adjustment method disclosed in the present application also includes: obtaining a preset number of light intensity data groups by sliding value acquisition; calculating the average value of the light intensity data group; when the average value is greater than a first preset value and the current gear is at the lowest gear, determining that the finger has fallen off and outputting a warning message.

[0101] Specifically, the light intensity data corresponding to the target finger at the lowest gear is obtained according to a preset sliding method; when the sliding window meets the preset sliding window, the average value of the light intensity data group corresponding to each sliding window is determined in turn; when the average value is greater than the first preset value and the current gear is the lowest gear, it is determined that the finger has fallen off and an early warning message is output.

[0102] After the current gear is adjusted based on the light intensity data group, the target finger status information needs to be determined in the process of obtaining the light intensity data corresponding to the next target finger, that is, when obtaining the light intensity data group corresponding to the target finger, if the target finger slips, the light intensity data corresponding to the target finger needs to be obtained again. The way to determine whether the target finger slips is: obtain the light intensity data corresponding to the target finger at the lowest gear in a preset sliding manner; when the sliding window meets the preset sliding window, determine the average value of the light intensity data corresponding to each sliding window in turn; determine the state information of the target finger according to the average value of the light intensity data corresponding to each sliding window.

[0103] The preset sliding mode is to slide to obtain the light intensity data corresponding to windows 1-8, 2-9, 3-10, ..., and the number of sliding windows is related to the target preset threshold and the light intensity data included in the sliding window. For example, when the target preset threshold is 30, the light intensity data included in the sliding window is 8, and the number of sliding windows is 23. When the average value of the light intensity data included in a sliding window fluctuates greatly, the light intensity data collected in the sliding window will show the phenomenon of the target finger slipping.

[0104] In addition, in the embodiment of the present disclosure, by adjusting the current of the oximeter, it is ensured that the oximeter outputs a stable waveform, thereby achieving accurate detection of human blood oxygen changes based on the waveform output by the oximeter.

[0105] The following will be explained through specific examples, such as Figure 2As shown, firstly, step S11 is executed to adjust the oximeter to the initial current gear, which is the middle gear in the oximeter current gear, and then step S12 is executed to obtain the light intensity data corresponding to the target finger at the initial current gear. Step S13 is to determine the state information of the target finger according to the preset sliding mode. The specific process of step S13 is to first obtain the light intensity data corresponding to the target finger at the lowest gear according to the preset sliding mode, and then determine the average value of the light intensity data corresponding to each sliding window in turn, and finally determine the state information of the target finger according to the average value of the light intensity data corresponding to each sliding window. When the state information of the target finger is in the non-falling state, step S14 is executed to determine whether the acquired light intensity data corresponding to the target finger meets the target preset threshold value. When the acquired light intensity data corresponding to the target finger meets the first target preset threshold value (100), step S15 is executed. When the acquired light intensity data corresponding to the target finger does not meet the first target preset threshold value, step S20 is jumped to determine whether the light intensity data corresponding to the target finger meets the second target preset threshold value (30). In step S15, the average value DC of the light intensity data group corresponding to the target finger is obtained. Step S16: the target finger is obtained. The difference AC between the maximum and minimum values ​​of the light intensity data in the light intensity data group corresponding to the target finger, step S17, determine the perfusion index according to the average value of the light intensity data group and the difference between the maximum and minimum values ​​of the light intensity data in the light intensity data group, step S18, determine whether the perfusion index is less than 0.4, when the perfusion index is less than 0.4, increase the current by one gear, when the perfusion index is greater than 0.4, continue to S19, determine whether the perfusion index is greater than 1, when the perfusion index is greater than 1, increase the current by one gear, when the perfusion index is less than 1, then execute step S20, determine whether the light intensity data included in the light intensity data group corresponding to the target finger meets the second target A preset threshold is set as the target. When the light intensity data included in the light intensity data group meets the second target preset threshold, step S21 is executed to calculate the average light intensity of the light intensity data corresponding to the second target preset threshold. According to the average light intensity of the light intensity data obtained by calculation, step S22 is executed to determine whether the average light intensity exceeds the upper limit. When the average light intensity exceeds the upper limit, the current is lowered by one level. When the average light intensity does not exceed the upper limit, step S23 is executed to determine whether the average light intensity is less than the lower line. When the average light intensity is less than the lower line, the current is increased by one level. When the average light intensity is not less than the lower limit, return to step S12 to obtain the next group of light intensity data groups, and continue the above-mentioned cyclic adjustment.
