Description

Technical Field

[0001] This application relates to the field of modern TCM technology, and in particular to a TCM blood pressure and pulse detection system, method and equipment. Background Technology

[0002] In the past, the training of TCM practitioners was extremely difficult because pulse diagnosis techniques could not be standardized or made objective. Even among skilled pulse diagnostics, it was hard to reach a consensus. Furthermore, the difficulties and instability caused by human factors in the process of TCM pulse diagnosis could not be avoided, and it was also difficult to pass on the knowledge to each other.

[0003] Therefore, there is an urgent need to provide a standardized pulse detection system based on the physical essence of pulse diagnosis techniques, to automate the classification of the 27 or 30 pulse types in traditional Chinese medicine for blood pressure, in order to make up for the above-mentioned deficiencies. Summary of the Invention

[0004] This application provides a traditional Chinese medicine blood pressure pulse detection system, method, and device to achieve more accurate pulse detection, identification, and classification of the pulse of the target based on the arterial blood pressure information of the target.

[0005] This application provides a traditional Chinese medicine blood pressure and pulse detection system, comprising:

[0006] An arterial blood pressure information acquisition module is used to acquire arterial blood pressure information of the target being measured; wherein, the arterial blood pressure information includes the mean arterial blood pressure of the target being measured, and the mean pressure is: the average arterial blood pressure during one cardiac cycle when the cuff pressure is lower than the diastolic pressure;

[0007] The first pulse classification module is used to classify the pulse of the target's blood pressure in traditional Chinese medicine by comparing the average pressure of the target's arterial blood pressure with a preset average pressure threshold. The pulse categories in the first stage include deep pulse, floating pulse, and neither floating nor deep pulse.

[0008] This system enables a more accurate classification of the pulse characteristics of the target in Traditional Chinese Medicine (TCM) based on the target's arterial blood pressure information, classifying it as a deep pulse, a floating pulse, or a pulse that is neither deep nor floating.

[0009] In some embodiments, a first-stage pulse classification of the target's blood pressure pulse is performed by comparing the mean arterial blood pressure of the target with a preset mean blood pressure threshold, including:

[0010] When the average pressure is less than a preset first average pressure threshold, the pulse pattern of the blood pressure of the target under test is determined to be a floating pulse.

[0011] If the average pressure is greater than a preset second average pressure threshold, then the pulse pattern of the measured target's blood pressure is determined to be a deep pulse.

[0012] If the average pressure is between the preset first average pressure threshold and the preset second average pressure threshold, then the pulse pattern of the measured target in traditional Chinese medicine is determined to be a pulse that is neither floating nor sinking.

[0013] Wherein, the first average pressure threshold is less than the second average pressure threshold.

[0014] This system allows for the determination of whether the pulse pattern of the target's blood pressure is a floating pulse, a deep pulse, or a pulse that is neither floating nor deep, based on the average arterial blood pressure of the target.

[0015] In some embodiments, the arterial blood pressure information may also include the pulse pressure difference of the arterial blood pressure of the target being measured;

[0016] The system also includes:

[0017] The second pulse classification module is used to classify the pulse characteristics of the target's blood pressure in traditional Chinese medicine by comparing the pulse pressure difference of the target's arterial blood pressure with a preset pulse pressure difference threshold. The pulse characteristics in the second stage include full pulse, weak pulse, and neither full nor weak pulse.

[0018] This system allows for the classification of the pulse characteristics of the target's arterial blood pressure into three categories based on the pulse pressure difference: full pulse, weak pulse, and neither full nor weak pulse, according to traditional Chinese medicine principles.

[0019] In some embodiments, a second-stage pulse pattern classification of the target's blood pressure pulse is performed by comparing the pulse pressure difference of the target's arterial blood pressure with a preset pulse pressure difference threshold, including:

[0020] If the pulse pressure difference is less than the preset first pulse pressure difference threshold, then the pulse pattern of the measured target's blood pressure is determined to be a weak pulse.

[0021] If the pulse pressure difference is greater than the preset second pulse pressure difference threshold, then the pulse pattern of the measured target's blood pressure is determined to be a real pulse.

[0022] If the pulse pressure difference is between the first pulse pressure difference threshold and the second pulse pressure difference threshold, then the pulse pattern of the measured target in traditional Chinese medicine is determined to be a pulse that is neither deficient nor excessive.

[0023] Wherein, the first pulse pressure threshold is less than the second pulse pressure threshold.

[0024] This system allows for the determination of whether the pulse pattern of the target's arterial blood pressure is a weak pulse, a strong pulse, or a pulse that is neither weak nor strong, based on the pulse pressure difference of the target's arterial blood pressure.

[0025] In some embodiments, the system further includes:

[0026] The third pulse classification module is used to determine the pulse amplitude rhythm of the target being tested, and to perform a third-stage pulse classification of the target's blood pressure pulse according to the pulse amplitude rhythm of the target being tested; wherein, the pulse amplitude rhythm of the target being tested refers to the correspondence between the amplitude change of the target's pulse and the cuff pressure change.

[0027] The pulse classification in the third stage includes: soft pulse, hesitant pulse, scattered pulse, floating pulse, hollow pulse, surging pulse, leather pulse, faint pulse, short pulse, non-floating pulse, slow pulse, arterial pulse, long pulse, thin pulse, large pulse, wiry pulse, tense pulse, solid pulse, weak pulse, deep pulse, hidden pulse, and firm pulse.

[0028] This system allows for the classification of the pulse patterns of the target's blood pressure according to the pulse amplitude rhythm. The classification includes soft pulse, hesitant pulse, scattered pulse, floating and weak pulse, floating pulse, hollow pulse, surging pulse, leather pulse, faint pulse, short pulse, non-floating and weak pulse, slow pulse, arterial pulse, long pulse, thin pulse, large pulse, wiry pulse, tense pulse, solid pulse, weak pulse, deep pulse, hidden pulse, and firm pulse.

[0029] In some embodiments, the third-stage pulse classification of the blood pressure pulse of the target under test based on the pulse amplitude rhythm includes:

[0030] Generate a pulse amplitude rhythm image for the pulse classification of the target under test. The pulse amplitude rhythm image is a function graph used to present the correspondence between the amplitude change of the pulse of the target under test and the cuff pressure change. The correspondence reflects the pulse classification of the target under test.

[0031] Among them, the waveform on the pulse amplitude rhythm image of floating pulse type is below the preset first average pressure threshold;

[0032] The waveform on the pulse amplitude rhythm image of deep pulse type is above the preset second average pressure threshold;

[0033] The waveform on the pulse amplitude rhythm image of a pulse that is neither floating nor sinking appears in the range between the first average pressure threshold and the second average pressure threshold;

[0034] and:

[0035] In the pulse amplitude rhythm image of the virtual pulse type, the pulse amplitude of the first pulse after the diastolic pressure of the target being measured is lower than the preset first pulse pressure difference threshold.

[0036] In the pulse amplitude rhythm image of the real pulse type, the pulse amplitude of the first pulse after the diastolic pressure of the target being measured is higher than the preset second pulse pressure difference threshold.

[0037] In the pulse amplitude rhythm image of the non-false pulse type, the pulse amplitude of the first pulse after the diastolic pressure of the target being measured is between the first pulse pressure difference threshold and the second pulse pressure difference threshold;

[0038] Among them, the soft pulse, hesitant pulse, scattered pulse, superficial pulse, floating pulse, hollow pulse, surging pulse, and leather pulse all belong to the floating pulse category, and their waveforms in the pulse amplitude rhythm image are displayed in the range where the cuff pressure is lower than the preset first average pressure threshold; among them, the soft pulse, hesitant pulse, and scattered pulse all belong to the deficient pulse category, and the amplitude values ​​of the soft pulse, hesitant pulse, and scattered pulse are all lower than the preset first pulse pressure difference threshold; the surging pulse and leather pulse all belong to the solid pulse category, and the amplitude values ​​of the surging pulse and leather pulse are all higher than the preset second pulse pressure difference threshold; the superficial pulse, floating pulse, and hollow pulse all belong to the neither superficial nor solid pulse category, and the amplitude values ​​of the superficial pulse, floating pulse, and hollow pulse are all between the first pulse pressure difference threshold and the second pulse pressure difference threshold;

[0039] The weak pulse, deep pulse, firm pulse, and hidden pulse all belong to the deep pulse category, and their waveforms in the pulse amplitude rhythm diagram all show a cuff pressure higher than a preset second average pressure threshold. Among them, the weak pulse belongs to the false pulse category, and the amplitude value of the weak pulse is lower than a preset first pulse pressure difference threshold. The firm pulse and hidden pulse both belong to the real pulse category, and the amplitude values ​​of the firm pulse and hidden pulse are higher than a preset second pulse pressure difference threshold. The deep pulse belongs to the neither false nor real pulse category, and the amplitude value of the deep pulse is higher than the preset first pulse pressure difference threshold and lower than the preset second pulse pressure difference threshold.

[0040] The pulses described are: faint pulse, short pulse, non-superficial pulse, slow pulse, thready pulse, long pulse, arterial pulse, full pulse, tense pulse, wiry pulse, and large pulse. All of these belong to the category of pulses that are neither superficial nor deep. Specifically, faint and short pulses belong to the category of weak pulses, and their amplitude values ​​are lower than a preset first pulse pressure difference threshold. Full, tense, wiry, and large pulses belong to the category of full pulses, and their amplitude values ​​are higher than a preset second pulse pressure difference threshold. Non-superficial pulses, slow pulses, thready pulses, arterial pulses, and long pulses belong to the category of pulses that are neither superficial nor full, and their amplitude values ​​are higher than the preset first pulse pressure difference threshold and lower than the preset second pulse pressure difference threshold.

[0041] This system generates pulse amplitude rhythm images for pulse classification of the target being tested, and determines the superficiality and solidity of the pulse based on the pulse amplitude rhythm images of each pulse type.

[0090] This system allows for the determination of whether the pulse of the target is a normal pulse, slow pulse, moderate pulse, rapid pulse, fast pulse, or faint pulse based on the rhythm and rate of the pulse.

[0091] In some embodiments, before comparing the mean arterial blood pressure of the target with a preset threshold, the first pulse classification module is further configured to:

[0092] Determine whether the pulse wave of the target being tested has two peaks;

[0093] When biphasic pulses are present: if the average pressure is less than a preset first average pressure threshold, the pulse pattern of the tested target's blood pressure is determined to be a surging pulse; if the average pressure is greater than the preset first average pressure threshold, the pulse pattern of the tested target's blood pressure is determined to be a slippery pulse.

[0094] When there is no biphasic pulse, or after determining that the pulse pattern of the target's blood pressure belongs to the surging or slippery pulse according to traditional Chinese medicine, the pulse pattern of the target's blood pressure is classified in the first stage by comparing the average pressure of the target's arterial blood pressure with a preset threshold.

[0095] This system enables the determination of whether the pulse of the target is a surging pulse or a slippery pulse based on the pulse wave of the target.

[0098] By comparing the average arterial blood pressure of the target with a preset average blood pressure threshold, the pulse pattern of the target's blood pressure is classified in the first stage according to traditional Chinese medicine. The pulse pattern categories in the first stage include deep pulse, floating pulse, and neither floating nor deep pulse.

[0099] This method enables a more accurate classification of the pulse characteristics of the target's blood pressure in Traditional Chinese Medicine (TCM) based on the target's arterial blood pressure information.

[0116] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0117] This application provides a traditional Chinese medicine blood pressure pulse detection system, method, and device to achieve more accurate pulse detection, identification, and classification of the pulse of the target based on the arterial blood pressure information of the target.

[0118] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0119] The terms "first," "second," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0120] The following examples and embodiments are to be understood as illustrative only. While this specification may refer to "a," "an," or "some" examples or embodiments in several places, this does not mean that every such reference relates to the same example or embodiment, nor does it mean that the feature applies only to a single example or embodiment. Individual features of different embodiments may also be combined to provide other embodiments. Furthermore, terms such as "comprising" and "including" should be understood not to limit the described embodiments to consisting only of those features mentioned; such examples and embodiments may also include features, structures, units, modules, etc., not specifically mentioned.

[0121] The various embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that the order in which the embodiments are presented in this application represents only a chronological order and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0122] It should be noted that the technical solution provided in this application embodiment is illustrated by taking pulse classification based on arterial blood pressure data collected by a blood pressure monitor as an example, but it is not limited thereto.

[0123] The following are explanations of some of the terms that appear in the text:

[0124] 1. In the embodiments of this application, the term "pulse amplitude graph" refers to a function graph showing the relationship between the change in pulse amplitude and the change in cuff pressure. The vertical axis of the function graph is the amplitude value of each pulse during the cuff deflation process, and the horizontal axis is the cuff pressure value corresponding to each pulse. The cuff pressure value, or cuff pressure for short, refers to the pressure value generated when inflating and deflating the cuff during blood pressure measurement.

[0125] 2. In the embodiments of this application, the term "rising edge time" refers to the duration of the rising edge of the pulse wave. The longer the rising edge time, the worse the blood flow and the greater the blood viscosity. Conversely, the shorter the rising edge time, the better the blood flow.

[0126] 3. In the embodiments of this application, the term "concave coefficient" refers to the concave coefficient between two peaks of a pulse wave, which is the ratio of the value of the concave portion between the main peak and the next peak to the value of the highest peak, and the unit is pressure value;

[0127] 4. In the embodiments of this application, the term "waveform coefficient" refers to the area of ​​the waveform, i.e., the denominator, which is the peak of the pulse wave and the time of the horizontal axis. The actual area of ​​the waveform is used as the numerator. The ratio of the numerator to the denominator is the waveform coefficient, which is also equivalent to the duty cycle (i.e., the degree of fullness).

[0128] 5. In the embodiments of this application, the term "not large and flat" refers to the change in the amplitude of the pulse wave (i.e., the pulse amplitude rate). If the difference between the amplitude of the pulse wave and the cuff pressure is very small (within a preset range), it is considered large and flat; otherwise, it is considered not large and flat.

[0129] In the past, cultivating pulse diagnosis skills in the training of TCM practitioners was extremely difficult, and even among highly skilled pulse diagnoses, consistency was rare. Therefore, it is necessary to start from the physical essence of pulse diagnosis and seek a path that is similar to pulse diagnosis in terms of physical principles.

[0130] In his commentary on the book "Binhu Pulse Study", Li Shizhen clearly pointed out that the six pulse types of "floating", "sinking", "slow", "rapid", "deficient" and "excessive" perfectly embody the three dimensions of "exterior", "interior", "cold", "heat", "deficient" and "excess" in traditional Chinese medicine. By combining the pulse characteristics of these three dimensions, one can roughly determine the condition of the disease. All other pulse types are further refinements based on these six general pulse types.

[0131] Therefore, as long as we can understand the physical nature of the above six pulses by studying the process of arterial blood pressure measurement, we may be able to understand all 27 or 30 pulse types based on these six guiding pulses.

[0132] To address the aforementioned issues, this application provides a Traditional Chinese Medicine (TCM) blood pressure pulse detection system. This system, developed from a physical perspective, offers a novel approach to obtaining the 27 or 30 pulse patterns found in TCM. This method not only provides a more objective and stable way to obtain the 27 or 30 pulse patterns but also allows for quantification. The TCM blood pressure pulse detection system uses the mean arterial blood pressure (PM) as the basis for distinguishing and quantifying the pulse's depth; the pulse pressure difference (ΔP) as the basis for distinguishing and quantifying the pulse's strength; the amplitude variation of the pulse during cuff deflation (pulse amplitude rhythm) as a supplement to confirming its depth and pulse type classification; and the identification of pulse waveform, rhythm, and rate during cuff deflation as a summary for determining pulse type identification and classification. This allows for a more objective and quantifiable detection, identification, and extraction of TCM blood pressure pulse patterns.

[0133] See Figure 1This application provides a traditional Chinese medicine blood pressure and pulse detection system, which includes, for example, an arterial blood pressure information acquisition module 100, a first pulse classification module 200, a second pulse classification module 300, a third pulse classification module 400, a fourth pulse classification module 500, and a waveform determination module 600; wherein:

[0134] The arterial blood pressure information acquisition module 100 is used to acquire the arterial blood pressure information of the target being measured.

[0135] The first pulse classification module 200 is used to classify the pulse of the target in traditional Chinese medicine by comparing the average pressure of the arterial blood pressure of the target with a preset average pressure threshold, and classifying the pulse as deep pulse, floating pulse, or neither floating nor deep pulse; it is also used to determine whether the pulse wave of the target has a double peak, and when a double peak exists, to determine whether the pulse wave of the target belongs to a bounding pulse or a slippery pulse.

[0136] The second pulse classification module 300 is used to classify the pulse characteristics of the target's arterial blood pressure into full pulse, weak pulse, and neither full nor weak pulse by comparing the pulse pressure difference of the target's arterial blood pressure with a preset pulse pressure difference threshold.

[0137] The third pulse classification module 400 is used to classify the pulse characteristics of the target's blood pressure according to the pulse amplitude rhythm of the target, including soft pulse, hesitant pulse, scattered pulse, floating and weak pulse, floating pulse, hollow pulse, surging pulse, leather pulse, faint pulse, short pulse, non-floating and weak pulse, slow pulse, arterial pulse, long pulse, thin pulse, large pulse, wiry pulse, tense pulse, solid pulse, weak pulse, deep pulse, hidden pulse, and firm pulse.

[0138] The fourth pulse classification module 500 is used to classify the pulse of the target in traditional Chinese medicine based on the rhythm and rate of the pulse of the target, such as knotted pulse, intermittent pulse, hurried pulse, normal pulse, slow pulse, moderate pulse, rapid pulse, quick pulse, acute pulse, and detached pulse.

[0139] The waveform determination module 600 is used to determine the waveform corresponding to the blood pressure pulse of the target in traditional Chinese medicine based on the pulse shape (i.e., the waveform of the pulse wave) of the target.

[0140] See Figure 2 This application provides an embodiment of a method for classifying the pulse characteristics of a target's blood pressure into a first category of pulse characteristics (i.e., deep pulse, floating pulse, and neither floating nor deep pulse) (for example, by performing this through the aforementioned first pulse characteristic classification module 200). The specific steps include:

[0141] Step S101, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0142] Step S102: Based on the arterial blood pressure information obtained in step S101, determine whether the pulse wave of the target being measured has two peaks (i.e., each pulse wave has two peaks, which is determined by signal processing). If it exists, proceed to step S103; if it does not exist, proceed to step S104.

[0143] Step S103: Calculate the mean blood pressure P based on the arterial blood pressure information obtained in step S101. M If P M If the blood pressure is <80 mmHg, then the pulse pattern of the person being measured according to Traditional Chinese Medicine (TCM) is a bounding pulse; if P M If the blood pressure is >80 mmHg, then the pulse pattern of the target in Traditional Chinese Medicine is a slippery pulse.

[0144] Step S104: Calculate the mean blood pressure P based on the arterial blood pressure information obtained in step S101. M If P M If the blood pressure is <80 mmHg, then the pulse pattern of the measured target in Traditional Chinese Medicine is a floating pulse; if P M If the blood pressure pulse of the target is within the range of [80 mmHg, 105 mmHg], then the pulse pattern according to Traditional Chinese Medicine is neither floating nor deep; if P M If the blood pressure is >105 mmHg, then the pulse pattern of the target in Traditional Chinese Medicine is a deep pulse.

[0145] See Figure 4 This application provides an embodiment of a method for classifying the pulse characteristics of a target's blood pressure into a second category (i.e., a full pulse, a weak pulse, or a pulse that is neither full nor weak) (for example, by performing this classification via the aforementioned second pulse classification module 300). The specific steps include:

[0146] Step S201, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0147] Step S202: The first pulse classification module 200 determines whether the pulse wave of the target being measured has a double peak based on the arterial blood pressure information obtained in step S201. If it does, proceed to step S203; if it does not, proceed to step S204.

[0148] Step S203: The first pulse classification module 200 calculates the mean pressure P based on the arterial blood pressure information obtained in step S201. M If P M If the blood pressure is <80 mmHg, then the pulse pattern of the person being measured according to Traditional Chinese Medicine (TCM) is a bounding pulse; if P M If the blood pressure is >80 mmHg, then the pulse pattern of the target in Traditional Chinese Medicine is a slippery pulse.

[0149] Step S204: The first pulse classification module 200 calculates the mean pressure P based on the arterial blood pressure information obtained in step S201.M According to P M Determine the superficial or deep category of the pulse in Traditional Chinese Medicine for the target blood pressure.

[0150] Step S205: Calculate the pulse pressure difference ΔP based on the arterial blood pressure information obtained in step S201. If ΔP < 25 mmHg, the pulse pattern of the measured target in traditional Chinese medicine is a weak pulse; if ΔP is within the range of [25 mmHg, 50 mmHg], the pulse pattern of the measured target in traditional Chinese medicine is a neither weak nor strong pulse; if ΔP > 50 mmHg, the pulse pattern of the measured target in traditional Chinese medicine is a strong pulse.

[0151] See Figure 5 This application provides a method for classifying the pulse characteristics of a target's blood pressure into a third category of pulse characteristics (i.e., soft pulse, hesitant pulse, scattered pulse, floating and weak pulse, floating pulse, hollow pulse, surging pulse, and leather pulse) (for example, executed through the aforementioned third pulse characteristic classification module 400). Assuming the target's blood pressure pulse characteristics belong to the first category of pulse characteristics, the specific steps include:

[0152] Step S301, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0153] Step S302: The first pulse classification module 200 determines that the pulse wave of the target does not have a double peak based on the arterial blood pressure information obtained in step S301.

[0154] Step S303: The second pulse classification module 300 calculates the mean pressure P based on the arterial blood pressure information obtained in step S301. M P was obtained M <80, indicating that the pulse pattern of the target's blood pressure in traditional Chinese medicine belongs to the floating pulse in the second category of pulse patterns;

[0155] Step S304: Calculate the pulse pressure difference ΔP based on the arterial blood pressure information obtained in step S301. If ΔP < 25 mmHg, proceed to step S305; if ΔP is within the range of [25 mmHg, 50 mmHg], proceed to step S307; if ΔP > 50 mmHg, proceed to step S309.

[0156] Step S305: Based on the arterial blood pressure information obtained in step S301, determine the systolic blood pressure P. S Is it less than 80 mmHg? If P S If the blood pressure is less than 80 mmHg, proceed to step S306; otherwise, the blood pressure pulse of the target under test belongs to the scattered pulse in the third category of pulse patterns.

[0157] Step S306: Determine whether the leading edge time of the pulse wave of the target being tested is greater than 120ms. If the leading edge time is greater than 120ms, the pulse pattern of the target being tested in traditional Chinese medicine blood pressure belongs to the soft pulse in the third type of pulse pattern; if not, it belongs to the hesitant pulse.

[0158] Step S307: Based on the arterial blood pressure information obtained in step S301, determine whether the concavity coefficient of the pulse amplitude is greater than 0.2. If the concavity coefficient is greater than 0.2, then the pulse pattern of the measured target in traditional Chinese medicine belongs to the hollow pulse in the third type of pulse pattern; if not, proceed to step S308.

[0159] Step S308: Compare the waveform coefficient K of the pulse wave of the target to be tested with the preset threshold, and compare the pulse pressure difference ΔP. If ΔP < 30 mmHg, the pulse pattern of the target's blood pressure in traditional Chinese medicine belongs to the floating and weak pulse in the third type of pulse pattern; otherwise, the pulse pattern of the target's blood pressure in traditional Chinese medicine belongs to the floating pulse in the third type of pulse pattern.

[0160] Step S309: Based on the arterial blood pressure information obtained in step S301, determine whether the waveform coefficient K of the pulse wave is less than 0.4. If K < 0.4, the pulse pattern of the measured target in traditional Chinese medicine belongs to the surging pulse in the third type of pulse pattern; if not, it belongs to the leather pulse.

[0161] See Figure 6 This application provides a method for classifying the pulse characteristics of a target's blood pressure using a third category of pulse patterns (i.e., faint pulse, short pulse, non-floating pulse, slow pulse, thready pulse, long pulse, arterial pulse, full pulse, tense pulse, wiry pulse, and large pulse) (for example, executed through the aforementioned third pulse pattern classification module 400). Assuming the target's blood pressure pulse belongs to the first category of pulse patterns (neither floating nor sinking), the specific steps include:

[0162] Step S401, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0163] Step S402: The first pulse classification module 200 determines that the pulse wave of the target does not have a double peak based on the arterial blood pressure information obtained in step S401.

[0164] Step S403: The second pulse classification module 300 calculates the mean pressure P based on the arterial blood pressure information obtained in step S401. M P was obtained M Within the range of [80 mmHg, 105 mmHg], the pulse pattern of the measured target's blood pressure in traditional Chinese medicine is determined to be a non-superficial and non-deep pulse in the second category of pulse patterns.

[0165] Step S404: Calculate the pulse pressure difference ΔP based on the arterial blood pressure information obtained in step S401. If ΔP < 25 mmHg, proceed to step S405; if ΔP is within the range of [25 mmHg, 50 mmHg], proceed to step S406; if ΔP > 50 mmHg, proceed to step S409.

[0166] Step S405: Determine whether the pulse pressure difference ΔP of the target is less than 10 mmHg. If ΔP < 10 mmHg, the pulse pattern of the target's blood pressure in Traditional Chinese Medicine (TCM) belongs to the faint pulse in the third category of pulse patterns. If 10 mmHg ≤ ΔP < 15 mmHg, the pulse pattern of the target's blood pressure in TCM belongs to the short pulse in the third category of pulse patterns. If 15 mmHg ≤ ΔP < 25 mmHg, the pulse pattern of the target's blood pressure in TCM belongs to the non-floating and weak pulse in the third category of pulse patterns.

[0167] Step S406: Determine whether the heart rate of the target being tested is greater than 89 beats / min. If so, the pulse pattern of the target's blood pressure in traditional Chinese medicine belongs to the arterial pulse pattern in the third category. If not, proceed to step S407.

[0168] Step S407: Determine whether the heart rate of the target being tested is less than 63. If so, the pulse pattern of the target's blood pressure in Traditional Chinese Medicine belongs to the slow pulse pattern in the third category. If not, proceed to step S408.

[0169] Step S408: Determine whether the waveform coefficient K of the pulse wave of the target being tested is greater than 0.45. If so, the pulse of the target being tested in traditional Chinese medicine belongs to the long pulse in the third type of pulse; if not, it belongs to the thin pulse.

[0170] Step S409: Determine whether the pulse pressure difference ΔP of the target being tested is greater than 60. If yes, proceed to step S410; otherwise, proceed to step S411.

[0171] Step S410: Determine whether the pulse wave of the target is non-sine based on the waveform coefficient K of the target's pulse wave (e.g., K<0.45 is non-sine). If it is, the pulse wave of the target's blood pressure belongs to the large pulse in the third type of pulse. If not, proceed to step S411.

[0172] Step S411: Determine whether the pulse wave of the target is not large and flat based on the pulse amplitude rate of the target's pulse wave (if the change in pulse amplitude rate is within the preset range, i.e., the difference is very small, then the pulse wave is large and flat; otherwise, it is not large and flat). If so, the pulse wave of the target's blood pressure in traditional Chinese medicine belongs to the wiry pulse in the third type of pulse. If not, proceed to step S412.

[0173] Step S412: Determine whether the pulse wave of the target is wiry (e.g., K≥0.45) based on the waveform coefficient K of the target's pulse wave. If so, the target's pulse pattern in traditional Chinese medicine belongs to the tense pulse in the third type of pulse pattern; otherwise, it belongs to the solid pulse.

[0174] See Figure 7 This application provides a method for classifying the pulse characteristics of a target's blood pressure into a third category (i.e., weak pulse, deep pulse, firm pulse, and hidden pulse) using traditional Chinese medicine (TCM) methods (e.g., through the aforementioned third pulse classification module 400). Assuming the target's TCM blood pressure pulse belongs to the deep pulse category within the first category, the specific steps include:

[0175] Step S501, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0176] Step S502: The first pulse classification module 200 determines that the pulse wave of the target does not have a double peak based on the arterial blood pressure information obtained in step S501.

[0177] Step S503: The second pulse classification module 300 calculates the mean pressure P based on the arterial blood pressure information obtained in step S501. M P was obtained M >105 mmHg, indicating that the pulse pattern of the measured target's blood pressure in traditional Chinese medicine belongs to the deep pulse in the second type of pulse pattern;

[0178] Step S504: Calculate the pulse pressure difference ΔP based on the arterial blood pressure information obtained in step S501. If ΔP < 25 mmHg, the pulse pattern of the measured target in traditional Chinese medicine belongs to the weak pulse in the third type of pulse pattern; if ΔP is in the range of [25 mmHg, 50 mmHg], the pulse pattern of the measured target in traditional Chinese medicine belongs to the deep pulse in the third type of pulse pattern; if ΔP > 50 mmHg, proceed to step S505.

[0179] Step S505: Determine whether the waveform coefficient K of the pulse wave of the target being tested is less than 0.45. If so, the pulse pattern of the target being tested in traditional Chinese medicine belongs to the hidden pulse in the third type of pulse pattern. Otherwise, it belongs to the firm pulse.

[0180] See Figure 8 This application provides an embodiment of a method for classifying the pulse characteristics of a target's blood pressure into a fourth category of pulse characteristics (i.e., knotted pulse, intermittent pulse, hurried pulse, normal pulse, slow pulse, moderate pulse, rapid pulse, quick pulse, acute pulse, and detached pulse) (for example, executed through the aforementioned fourth pulse characteristic classification module 500). The specific steps include:

[0181] Step S601, for example Figure 3 As shown, the arterial blood pressure information of the target under test within one detection cycle is obtained through the arterial blood pressure information acquisition module 100;

[0182] Step S602: Based on the pulse rhythm and rate in the arterial blood pressure information, determine whether the pulse of the target being measured is arrhythmic. If yes, proceed to step S603; otherwise, proceed to step S606.

[0183] Step S603: Determine whether there are premature beats in the pulse of the target based on the arterial blood pressure information of the target. If so, the pulse of the target in traditional Chinese medicine blood pressure belongs to the knotted pulse in the fourth type of pulse. If not, proceed to step S604.

[0184] Step S604: Determine whether the target has bigeminy based on the arterial blood pressure information of the target. If yes, the target's pulse pattern in traditional Chinese medicine belongs to the intermittent pulse pattern in the fourth category. If not, proceed to step S605.

[0185] Step S605: Determine whether the target has atrial fibrillation based on the arterial blood pressure information of the target. If it exists, the target's TCM blood pressure pulse belongs to the fourth type of pulse, namely the hurried pulse. If it does not exist, proceed to step S606.

[0186] Step S606: Based on the arterial blood pressure information of the target, determine whether the number of pulses per breath (i.e., one breath) of the target is within [4 to 5]. If so, the pulse pattern of the target's blood pressure in traditional Chinese medicine belongs to the normal pulse in the fourth category of pulse patterns; if not, proceed to step S607.

[0187] Step S607: Based on the arterial blood pressure information of the target, determine whether the target's heart rate (HR) is less than 60 beats / min. If so, the target's TCM blood pressure pulse belongs to the slow pulse in the fourth category of pulse patterns. If not, proceed to step S608.

[0188] Step S608: Based on the arterial blood pressure information of the target, determine whether the target's heart rate (HR) is within the range of [60 beats / min, 70 beats / min]. If so, the target's TCM blood pressure pulse belongs to the slow pulse in the fourth type of pulse. If not, proceed to step S609.

[0189] Step S609: Based on the arterial blood pressure information of the target, determine whether the target's pulse rate is 6 beats per breath. If it is 6 beats per breath, the target's pulse rate in Traditional Chinese Medicine belongs to the rapid pulse in the fourth category of pulse patterns. If it is not 6 beats per breath, proceed to step S610.

[0190] Step S610: If the pulse rate of the target in one breath is 7 beats, then the pulse rate of the target in traditional Chinese medicine belongs to the rapid pulse in the fourth category of pulse patterns; if the pulse rate of the target in one breath is 8 beats, then the pulse rate of the target in traditional Chinese medicine belongs to the acute pulse in the fourth category of pulse patterns; if the pulse rate of the target in one breath is ≥9 beats, then the pulse rate of the target in traditional Chinese medicine belongs to the depleted pulse in the fourth category of pulse patterns.

[0191] See Figure 9 In this embodiment of the application, the waveform determination module 600 described above determines the waveform (i.e., pulse waveform) corresponding to the blood pressure pulse of the target in traditional Chinese medicine based on the pulse shape of the target.

[0192] In Traditional Chinese Medicine (TCM) pulse diagnosis, the variation in the pulse's pulsation felt by the doctor's fingers as they press from light to heavy pressure is called "external length." This sensation during pulse diagnosis can be visualized as a length diagram, for example... Figure 9 The first row of the diagram corresponding to each pulse pattern shown represents the different characteristics of different pulse patterns on the length chart.

[0193] For example Figure 9 As shown, if the pulse length charts for each subject (i.e., the test targets) could be obtained, it would provide a very important and visual supplement to the interpretation of pulse information. For example:

[0194] First, the pulse can be visually classified into floating pulse, neither floating nor sinking pulse, and sinking pulse from the pulse length chart of each examinee, as well as the pulse condition can be visually classified into weak and strong pulse.

[0195] Secondly, for example Figure 9 As shown, the pulse length curve of the hollow pulse has a bimodal characteristic, and the concavity coefficient of its pulse wave is >0.2.

[0196] Furthermore, from the pulse wave graph (the second row of the graph corresponding to each pulse pattern), there are four types of pulses with wiry characteristics (K≥0.45): wiry pulses with a floating nature are called "leather"; wiry pulses with a deep nature are called "firm"; wiry pulses with a large and flat length graph are called "tight"; only wiry pulses with a length graph that is not large and flat are called "wiry". It is evident that the length graph plays a decisive role in the characterization of a wiry pulse.

[0197] The analysis of pulse information using the aforementioned pulse length and shortness diagrams demonstrates their effectiveness in distinguishing between superficial, deep, weak, and strong pulses, as well as in interpreting specific types of wiry pulses. Their visual representation makes them easier to learn and master. However, these diagrams are based on the dynamic variations of fingertip sensation. In this embodiment, during arterial blood pressure measurement, the cuff pressure changes and related pulse information are simultaneously recorded and plotted as a "pulse amplitude rhythm" diagram, which is the aforementioned pulse length and shortness diagram. This pulse amplitude rhythm image serves as a visual supplement to the first pulse classification module 200 and the second pulse classification module 300; it also visually represents the pulse amplitude variation patterns of different pulse types with cuff pressure changes. Therefore, the pulse amplitude rhythm image is an indispensable visual means for pulse classification, truly realizing the graphical representation of the "pulse length and shortness diagram awareness" previously only understood by traditional pulse diagnosis experts. In other words, the pulse amplitude function graph proposed in this application is a personalized long / short graph. A new method is proposed to automatically obtain personalized long / short graphs, creating a new approach for the implementation of the third pulse classification module of this system, improving the accuracy and efficiency of long / short graph drawing, and avoiding the errors and inefficiencies caused by manually drawing long / short graphs.

[0198] In addition to the above Figure 5 , 6 The third type of pulse classification method provided in section 7, in some embodiments, can also utilize the aforementioned third pulse classification module to generate a pulse amplitude rhythm diagram for each pulse type based on the correspondence between the amplitude changes of the pulse of the tested target and the cuff pressure changes. Through the pulse amplitude rhythm diagram of each pulse type, the specific category, superficiality / deepness, and strength / weakness of each pulse type can be visually displayed, for example... Figure 9 As shown, the horizontal axis represents the cuff pressure value, and the vertical axis represents the amplitude value of each pulse during the cuff deflation process.

[0199] As can be seen from the pulse amplitude rhythm graph, the waveform of a floating pulse is below a preset first average pressure threshold, meaning that the cuff pressure value (horizontal axis) corresponding to its peak is less than the preset first average pressure threshold. The waveform of a deep pulse is above a preset second average pressure threshold, meaning that the cuff pressure value corresponding to its peak is greater than the preset second average pressure threshold. The waveform of a pulse that is neither floating nor deep is within the range between the first and second average pressure thresholds, meaning that the cuff pressure value corresponding to its peak is between the preset first and second average pressure thresholds.

[0200] As for the "empty," "full," and "neither empty nor full" pulses, these will also be reflected in the amplitude changes of the pulse in the pulse amplitude rhythm diagram. That is, the vertical axis of the pulse amplitude rhythm diagram can be quantified by the aforementioned preset first pulse pressure difference threshold and preset second pulse pressure difference threshold. For any pulse determined to be "empty," the pulse amplitude of the first pulse after diastolic pressure will definitely be lower than the preset first pulse pressure difference threshold. For any pulse determined to be "full," the pulse amplitude of the first pulse after diastolic pressure will definitely be higher than the preset second pulse pressure difference threshold. For any pulse determined to be "neither empty nor full," the pulse amplitude of the first pulse after diastolic pressure will definitely be between the aforementioned preset first pulse pressure difference threshold and preset second pulse pressure difference threshold.

[0201] From the pulse amplitude patterns of various pulse types, we can see that the floating pulse type includes: soft pulse, hesitant pulse, scattered pulse, floating and weak pulse, floating pulse, hollow pulse, surging pulse, and leather pulse. Among these, the weak pulse type includes soft pulse, hesitant pulse, and scattered pulse; the strong pulse type includes leather pulse and surging pulse; and the pulse type that is neither weak nor strong includes floating and weak pulse, floating pulse, and hollow pulse. The deep pulse type includes: weak pulse, deep pulse, firm pulse, and hidden pulse. Among these, the weak pulse type includes weak pulse; the strong pulse type includes firm pulse and hidden pulse; and the pulse type that is neither weak nor strong includes deep pulse. The pulse type that is neither floating nor deep includes: faint pulse, short pulse, non-floating and weak pulse, slow pulse, thready pulse, long pulse, arterial pulse, strong pulse, tense pulse, wiry pulse, and large pulse. Among these, the faint pulse and short pulse type belong to the weak pulse type; the strong pulse type includes strong pulse, tense pulse, wiry pulse, and large pulse; and the pulse type that is neither weak nor strong includes slow pulse, thready pulse, long pulse, and arterial pulse.

[0202] For example Figure 10 As shown, the horizontal axis represents the cuff pressure value (expressed as average pressure) for each pulse, and the vertical axis represents the amplitude change pattern of each pulse during cuff deflation (expressed as pulse pressure difference). For floating pulses, specifically those belonging to the weak pulse category, the peak in the pulse amplitude rhythm image is located to the left of the preset first average pressure threshold and below the preset first pulse pressure difference threshold.

[0203] Similarly, for the floating pulse type, the pulse that belongs to the solid pulse type has a peak in its pulse amplitude rhythm image that is located to the left of the preset first average pressure threshold and above the preset second pulse pressure difference threshold.

[0204] The pulse pattern belonging to the category of "neither weak nor strong" in the floating pulse pattern has a peak in its pulse amplitude rhythm image located to the left of the preset first average pressure threshold and between the preset first pulse pressure difference threshold and the preset second pulse pressure difference threshold.

[0205] The pulse pattern belonging to the category of weak pulse in the deep pulse pattern has a peak in its pulse amplitude rhythm image located to the right of the preset second average pressure threshold and below the preset first pulse pressure difference threshold.

[0206] The pulse pattern belonging to the solid pulse type in the deep pulse pattern has a peak in its pulse amplitude rhythm image located to the right of the preset second average pressure threshold and above the preset second pulse pressure difference threshold.

[0207] The pulse pattern of deep pulse belongs to the category of pulse that is neither weak nor strong. The peak of the pulse amplitude rhythm image is located to the left of the preset second average pressure threshold and between the preset first pulse pressure difference threshold and the preset second pulse pressure difference threshold.

[0208] The pulse that is neither floating nor sinking belongs to the category of weak pulse. The peak of its pulse amplitude rhythm image is located between the preset first average pressure threshold and the preset second average pressure threshold, and is below the preset first pulse pressure difference threshold.

[0209] The pulse that is neither floating nor sinking belongs to the solid pulse category. The peak of the pulse amplitude rhythm image is located between the preset first average pressure threshold and the preset second average pressure threshold, and is above the preset second pulse pressure difference threshold.

[0210] The pulse that is neither floating nor sinking belongs to the category of pulse that is neither weak nor strong. The peak of its pulse amplitude rhythm image is located between the preset first average pressure threshold and the preset second average pressure threshold, and is also located between the preset first pulse pressure difference threshold and the preset second pulse pressure difference threshold.

[0211] As can be seen, the third pulse classification module provided in this application embodiment is used to perform a third-stage pulse classification of the TCM blood pressure pulse of the target based on the pulse amplitude rhythm of the target. There are several possible methods. For example, it can directly generate and output a pulse amplitude rhythm image of the target's pulse classification; it can also classify the target's TCM blood pressure pulse based on the target's pulse amplitude rhythm and output the classification result; or it can output both simultaneously, that is, outputting not only the classification result but also the pulse amplitude rhythm image.

[0212] In summary, for example Figure 1 As shown in the embodiment of this application, a traditional Chinese medicine blood pressure and pulse detection system includes:

[0213] The arterial blood pressure information acquisition module 100 is used to acquire the arterial blood pressure information of the target being measured; wherein, the arterial blood pressure information includes the mean arterial blood pressure of the target being measured (i.e., the aforementioned P). M The mean pressure is: the average arterial blood pressure during one cardiac cycle when the cuff pressure is lower than the diastolic pressure;

[0214] The first pulse classification module 200 is used to classify the pulse of the target's blood pressure in traditional Chinese medicine by comparing the average pressure of the target's arterial blood pressure with a preset average pressure threshold. The pulse categories in the first stage include deep pulse, floating pulse, and neither floating nor deep pulse.

[0215] The first pulse classification module 200 performs the first stage of pulse classification based on the average arterial blood pressure of the target.

[0216] To determine whether the pulse pattern of the target's blood pressure is a floating pulse, a deep pulse, or a pulse that is neither floating nor deep, in some embodiments, the pulse pattern of the target's blood pressure is classified in the first stage by comparing the mean arterial blood pressure of the target with a preset mean blood pressure threshold, including:
