[0029] The specific scheme of an internal medicine massage device provided by the present application is described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1 , which shows a flow chart of a medical massage device provided by an embodiment of the present application, including the following steps:

[0031] Step 1: Obtain the vibration intensity and power of the vibration motor and the user's heart rate and blood oxygen value during the massage process of the internal medicine massage device.

[0032] The purpose of this embodiment is to accurately and effectively regulate the vibration power of the motor in the internal medicine massage device, avoid problems that affect the effect and comfort of the massage, and improve the effect and comfort of the massage for the user.

[0033] In order to accurately and effectively regulate the vibration power of the motor in the internal medicine massage device, during the process of performing internal medicine massage on the user, the vibration intensity and power signal of the vibration motor at each sampling moment are respectively sampled using a vibration sensor and a power sensor. At the same time, the heart rate sensor and the blood oxygen sensor are respectively sampled using a heart rate sensor and a blood oxygen sensor. In this embodiment, the sampling rate is 10 Hz, and data information within 2 minutes before the current moment is obtained, and the sampled data information is transmitted to the information processing unit.

[0034] Step 2: Determine the massage stimulation characteristic value at each sampling moment according to the difference in peak value and peak position of the vibration intensity at all sampling moments in the local moment set of each sampling moment.

[0035] Normally, changes in the vibration intensity of the vibration motor in an internal medicine massage device will affect the user's heart rate and blood oxygen changes. The faster the vibration intensity of the vibration motor changes and the higher the level of vibration intensity, the higher the massage stimulation produced on the user's body, and the more likely it is that the user will experience shortness of breath. At this time, the vibration parameters of the motor need to be accurately and effectively regulated to improve the massage effect and massage comfort.

[0036] Since the massage stimulation amount in different time periods has different characteristics, in order to accurately and effectively control the vibration parameters of the motor, it is first necessary to analyze the massage stimulation characteristics at different times. In this embodiment, the set of 30 sampling moments with the closest time interval to each sampling moment is used as the local moment set of each sampling moment, and the sequence composed of the vibration intensities of all sampling moments in the local time period of each sampling moment arranged in chronological order is used as the vibration intensity sequence of each sampling moment.

[0037] In order to analyze the changes in vibration intensity at different times, the vibration intensity sequence is used as the input of the AMPD peak detection algorithm (Automatic multiscale-based peak detection). The AMPD peak detection algorithm is used to obtain all peak positions and peak intensities in the vibration intensity sequence. The AMPD peak detection algorithm is a well-known technology and the specific process will not be repeated here.

[0038] Generally speaking, the smaller the distance between adjacent peak positions in a vibration intensity sequence and the greater the difference between the peak intensities corresponding to adjacent peak positions, the more significant the variation characteristics of the vibration intensity are, and the greater the degree of massage stimulation produced on the user's body.

[0039] Based on the above analysis, the massage stimulation characteristic value at each sampling moment during the massage process is calculated:

[0040] , where is the massage stimulation characteristic value at the t-th sampling moment, is the number of peaks in the vibration intensity sequence at the tth sampling moment, and are the i-th and i-1-th peak intensities in the vibration intensity sequence at the t-th sampling moment, is the Euclidean distance function, and are the i-th and i-1-th peak positions in the vibration intensity sequence at the t-th sampling moment, is the Euclidean distance between the i-th and i-1-th peak positions in the vibration intensity sequence at the t-th sampling moment. The smaller the Euclidean distance between adjacent peak positions and the greater the difference between the peak intensities, to a certain extent, the higher the degree of massage stimulation to the user, and the greater the massage stimulation characteristic value.

[0041] Step 3: Determine the physical sign stability coefficient at each sampling moment based on the degree of change of the blood oxygen value at all sampling moments in the local moment concentration of each sampling moment and the degree of confusion of the heart rate values ​​at all sampling moments, and obtain the motor vibration suitability at the sampling moment in combination with the massage stimulation characteristic value.

[0042] Generally speaking, there is a high correlation between the degree of massage stimulation and the user's heart rate and blood oxygen. For example, if the massage stimulation is too great, it is likely to cause the user's breathing to become rapid, with more chaotic heart rate changes and increased blood oxygen changes. At this time, the appropriate degree of motor vibration is relatively low, so the vibration parameters of the motor need to be accurately and effectively regulated to improve the comfort level of the massage.

[0043] In order to analyze the suitability characteristics of motor vibration during massage, the blood oxygen values ​​of all sampling moments in the local moment set of each sampling moment are sequenced in chronological order as the blood oxygen value sequence of each sampling moment, and the first-order difference sequence of the blood oxygen value sequence is calculated. The first-order difference sequence reflects the blood oxygen change characteristics in the user's body. The more positive values ​​in the first-order difference sequence, the more moments of increased blood oxygen, and the larger the cumulative sum of positive values, the greater the degree of increased blood oxygen, and the stronger the blood oxygen increase effect of the user's body.

[0044] Based on the above analysis, the normalized result of multiplying the cumulative sum of all the sequence values ​​greater than zero (that is, positive values) in the first-order difference sequence corresponding to each sampling moment by the number of the sequence values ​​greater than zero is calculated in the following formula for ease of understanding:

[0045] , where is the blood oxygen enhancement intensity at the t-th sampling moment, is the normalization function, is the number of positive values ​​in the first-order difference sequence of the blood oxygen value sequence at the t-th sampling moment, It is the sum of all positive values ​​in the first-order difference sequence of the blood oxygen value sequence at the t-th sampling moment. The more positive values ​​there are and the larger the sum of positive values ​​is, the greater the degree of blood oxygen increase is at this time, and the greater the blood oxygen increase intensity is.

[0046] Furthermore, according to the blood oxygen enhancement intensity at each sampling moment, combined with the information entropy of the heart rate values ​​at all sampling moments in the local moment concentration of each sampling moment, the vital sign stability coefficient at each sampling moment is calculated.

[0047] Preferably, in this embodiment, the vital sign stability coefficient at each sampling moment is the reciprocal of the sum of the blood oxygen enhancement intensity at each sampling moment and the information entropy. It should be noted that in this embodiment, in order to avoid the situation where the denominator is zero in the calculation process of the reciprocal and the ratio, 0.01 is added to the denominator in this embodiment. In the actual application process, the implementer can set it by himself. The calculation of information entropy is a well-known technology, and the specific process will not be repeated. The higher the blood oxygen enhancement intensity and the greater the information entropy, the more chaotic the heart rate changes in the user's body are and the stronger the blood oxygen enhancement effect is. To a certain extent, it reflects that the smaller the stability of the human body's vital signs at this time, the smaller the vital sign stability coefficient, that is, the smaller the suitability of the motor vibration simulated by the internal medicine massage device at this time.

[0048] Furthermore, the motor vibration suitability at each sampling moment is obtained based on the vital sign stability coefficient and the massage stimulation characteristic value at each sampling moment. Preferably, in this embodiment, the motor vibration suitability at each sampling moment is the ratio of the vital sign stability coefficient to the massage stimulation characteristic value at each sampling moment.

[0049] It can be understood that the larger the massage stimulation characteristic value and the smaller the physical sign stability coefficient, to a certain extent, it indicates that the massage stimulation degree of the internal medicine massage device is greater and the more unstable the human body signs are during massage, which more reflects that the massage technique simulated by the internal medicine massage device at this time cannot make the human body within a comfortable range, that is, the smaller the suitability of the motor vibration, the smaller the motor vibration suitability, and the more it is necessary to accurately and effectively control the vibration parameters of the motor to improve the comfort level of the massage.

[0050] Step 4: Obtain the characteristic intensity of pain during the massage process based on the average level and fluctuation of the motor vibration suitability at all sampling moments during the massage process.

[0051] Generally speaking, the more stable the change of motor vibration suitability between different sampling moments and the greater the average level of motor vibration suitability, the less pain caused by massaging the acupoints during massage; conversely, the more unstable the change of motor vibration suitability between different sampling moments and the smaller the average level of motor vibration suitability, the greater the pain caused by massaging the acupoints during massage, that is, the lower the comfort level of human body massage, and at this time, it is more necessary to accurately and effectively regulate the vibration power parameters of the motor to improve the massage effect and comfort level of the user.

[0052] Based on the above analysis, in this embodiment, the average level and fluctuation degree of the motor vibration suitability at all sampling moments during the massage process are combined to obtain the characteristic intensity of the pain sensation during the massage process. The specific expression is:

[0053] , where is the characteristic intensity of pain during massage, is an exponential function with a natural constant as base, is the mean value of the motor vibration suitability at all sampling moments during the massage process, is the standard deviation of the motor vibration suitability at all sampling moments during the massage process, To avoid a value with a denominator of zero, the value of this embodiment is 0.01. The larger the standard deviation and the smaller the mean, to a certain extent, it reflects that the more unstable the motor vibration suitability characteristics simulated by the internal medicine massage device and the lower the average level of the motor vibration suitability characteristics, the more likely it is that the massage acupoints will produce a greater degree of pain, and the greater the intensity of the pain characteristic, that is, the higher the degree of regulation of the motor vibration power parameters at this time.

[0054] Step 5: According to the difference between the characteristic intensity of the pain and the preset pain threshold, and the preset motor vibration power during the massage process, the power of the vibration motor of the massage device is adjusted.

[0055] In order to accurately and effectively regulate the power of the vibration motor in the internal medicine massage device, the characteristic intensity of pain during the massage process is used to calculate the adjustment power of the vibration motor:

[0056] , where is the adjustment power of the vibration motor, is the ceiling function, is the power of the vibration motor during massage. is the preset control level threshold, in this embodiment, the value is 30, is a preset pain threshold, and in this embodiment, the value is 0.4.

[0057] It can be understood that if the characteristic intensity of the pain sensation at the massage point at the current moment is less than or equal to the preset pain threshold, that is, the pain level at the massage point at the current moment is at a relatively low level, indicating that the motor vibration power of the internal medicine massage device is more suitable for continuing the massage, then the motor vibration power will not be adjusted, and the massage will continue with the motor vibration power at the current moment; if the characteristic intensity of the pain sensation at the massage point at the current moment is greater than the preset pain threshold, the pain level at the massage point at the current moment is at a relatively high level, indicating that the motor vibration power of the internal medicine massage device is no longer suitable for continuing the massage, and the adjustment power for adjusting the motor vibration power at the current moment is transmitted from the information processing unit to the motor control unit, and the motor vibration power of the vibration motor in the internal medicine massage device is reduced to the adjustment power by the motor control unit, thereby avoiding the problem of affecting the massage effect and comfort level, and improving the massage effect and comfort level of the user.
