Abstract

By a method to measure the blood pressure of a patient, a series of measurements for the diastolic, the systolic blood pressure and for the pulse rate are made. The results are analyzed in order to determine, and to display whether the patient is properly settled to a rest condition, and whether the patients blood pressure variation is found as being normal. Further it is investigated, whether there are high measurement result alterations due to artifacts. Highly altered results are excluded. If the results are sufficiently similar, an average of the result is made. If the results are not sufficiently similar, but still below pre-defined alteration limits, a weighted average is applied to the systolic and the diastolic blood pressure.

Description

552127 A7 ^-~ --- B7_______ 5. Invention: ΓΤ ~ The present invention relates to a method and device for non-invasively measuring a patient's blood pressure. Automatic electronic sphygmomanometers for non-invasively measuring a patient's blood pressure are widely known. This type of sphygmomanometer can basically measure the blood pressure values of systolic and diastolic blood pressure using a 'star method' such as vibration oscillometric measurement. During the measurement, 疋 is based on the pressure formed by the patient's armband during inflation and deflation. Therefore, it is basically possible to measure the systolic and diastolic blood pressure, and even the pulse beat rate according to the change in the pressure of the cuff. Automatic electronic blood pressure measurement devices are usually placed on the patient's upper arm, wrist or finger. When measuring, there are always some special reasons that cause errors. However, the inaccuracy of the measurement results may be due to the patient's normal physiological changes, inadequate meditation status, pathological blood pressure changes, or technical or usage problems related to threshold values. For example, positional changes during measurement may cause usability thresholds. If the patient follows the instruction manual of the measuring device correctly, errors caused by insufficient meditation and shaking threshold can be avoided. Generally speaking, as long as the patient is not in a state of sufficient meditation or the patient's position is shaking during the measurement, incorrect measurement results may be caused. This problem has been explained in the European patent application EP-99122743. 9 filed by the inventor at the same time. The purpose of the present invention is to overcome the lack of prior art, and in particular to provide an automatic, non-invasive sphygmomanometer and a method for measuring blood pressure to reduce such incorrect measurement results. In addition, another object of the present invention is to detect physiological blood pressure changes during blood pressure measurement. According to the present invention, in order to solve the above-mentioned purpose, the application based on this article is adopted (please read the precautions on the back before filling this page) ------- Order · IL ------ line 4 5. Description of the invention () The method of independent items of patent scope and the device for non-invasively measuring blood pressure. However, we found that there are four main reasons for the different blood pressure measurements before and after. It is a patient's normal physiological changes, inadequate static state, or pathological changes in stress. However, the pathological changes may be caused by various disorders of heart and blood organs. After that, its change is also affected by the chip value. Technical thresholds observed today, such as interference caused by the device, and usage thresholds, such as interference caused by patient shaking. Regarding the cause of each difference between successive measurement results, each has a specific probability. The slight difference without specific tendency is mainly due to the physiological changes in arterial blood pressure. The so-called mild-to-moderate differences are known to those who are familiar with the industry and follow specific rules of change, which may vary depending on the patient's meditation status. Generally speaking, 'In this case, the measurement of diastolic blood pressure = the result will rise in turn.' ^ Much of the high degree of change is due to layer values. The invention can improve the judgment of blood pressure measurement results. The present invention makes it possible to purely partition the error caused by frequency and the error caused by noise and / or physiology. In addition, the present invention has to = no relax to a meditation state.疋 Patient 疋 Non-invasive measurement, especially oscillometric measurement. According to the method of the present invention, in the first step, the patient's diastolic and systolic blood pressure values and pulsation rate,

This oscilloscope measurement method is known to those familiar with the industry, so it is not necessary to explain it in detail. After measuring diastole, systolic blood pressure value, and pulsatility rate in step-a)), repeat the first step a)) at least once. As a result, a series of continuous measurements of systolic and diastolic blood pressure and pulsatile rate are produced. The values specified below, such as the average, are then calculated. 0 In the next step, the continuous results of this series are automatically analyzed to determine the validity of the results. During the analysis, it can be confirmed whether the result meets one or more of the following conditions: Condition i ·): Confirm whether the measured results of the diastolic or systolic blood pressure value and the pulsation rate are steadily decreasing or increasing. If, in successive measurements, the systolic blood pressure value continuously decreases, or the diastolic blood pressure value continues to increase or decrease, and at the same time, the pulsation rate continuously decreases during the measurement period, it can be concluded that the patient is not in a state of sufficient meditation. The continuous decrease or increase is defined as follows, with reference to three measurements and analysis:

Si-S (i-l) < ASi, i-l (A)

Di-D (i-1) < Paper i-1 (Βϊ)

Di-D (i-l) < > ADi, i-1 (B2)

Description of the invention (ΔΡ21 =- 5 [bpm] If (A) and (B1) and (C) or (A) and (B2) and ⑹ 成) hold true. Condition ii, tension, systolic pressure, and pulsation rate == 11 The quantities are calculated according to the following formulas: 丄 Α-mean n mean n Σ where mean = R.

Ri n n; Σ 丨 heart-Σ end 丨 n --- I--I I I I--II I (Please read the precautions on the back before filling this page).

In the formula, Ri is the measurement result of diastolic, systolic blood pressure and pulsation rate, and η is the number of continuous measurements. The variable index is determined for all values of systolic, diastolic blood pressure, and pulsatile rate. The private number in this variable is an indicator that describes the stability of the measurement. If the variable index is 咼, it may be due to cardiovascular disorders that affect the stability of blood pressure, such as from arrhythmia, heart failure, or arterial control disorders. Therefore, the variable index of each summer test result can be compared with a predetermined or predeterminable variable index limit. If the variable index is above this limit, the patient / user can be informed of this result. It is recommended that the patient take another measurement. Condition i i i ·): According to another preferred embodiment of the present invention, it is determined whether the difference between successive measurement results of cardiac systolic waste and diastolic blood pressure is lower than a predetermined or predeterminable similarity limit. The similarity limit can be set, for example, to be: +/- 12 mmHg for diastolic blood pressure and +/- 18 mmHg for systolic blood pressure. If these differences are below the similarity limit, it can be assumed that the size of the blood wood paper is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 552127 A7 I -------------------- B7__ 5. Description of the invention () _ The measurement results are sufficiently similar to each other. In this case, based on the measurement results of cardiac, visceral contraction and diastolic 敎, to obtain the standard arithmetic mean. Condition 1v ·): Based on yet another—a better fact, it is to determine whether the difference between consecutive measurements of cardiac contraction and diastolic blood pressure is higher than a predetermined dissimilarity limit. In principle, the similarity limit can be set as follows: diastolic blood pressure to the heart is +/- 25_Hg, and diastolic blood pressure to the heart is + / _. Right this blood [One of the results in the test is below this limit, it can be assumed that this result is unique 'and attributed to independence. Therefore, such results in the measurement sequence are ignored. As a result of money, anyone who is higher than the so-called recording limit of condition iu but low = the so-called disparity limit of condition iv may be caused by pathological cardiovascular phenomena1 and may also be caused by the stratum value. Although the above conclusions are not correct, they cannot be completely ignored. We can weight the measurement results to an average value, which can reduce the impact of these values. Therefore, confirming the results of health tests is not as effective as the results of general measurements. By this measurement, the threshold value can be reduced. Each measurement result of θ I that does not exceed the so-called similarity limit of condition iii may be a correct measurement result. This is used to calculate the standard average result. In principle, we take three measurements. If one measurement result is omitted, J may perform a fourth measurement to produce three usable measurement results. If it is assumed that the value is measured by the measuring device in a specific way, it will be = a retest. Therefore, the maximum number of measurements of blood dust is taken as 5, including 3 measurements-this is a re-measurement caused by the threshold value, and one time may be determined by the degree of difference of the paper. χ 297 Extension ---------- ·

However, it is advisable to use three measurements' to control the entire measurement cycle, however, the cycle should not exceed $ to 7 minutes. The device according to the invention is the method described above, which measures the blood pressure of a patient non-invasively. For this purpose, the device is provided with a device for determining the patient's diastolic and systolic blood pressure and pulsatile rate by oscillometric measurement. The device is also provided with a device for storing a series of continuous measurements of systolic, diastolic blood pressure, and pulsatile rate. The device includes a device for analyzing a series of successive measurements of diastolic and systolic blood pressure and pulsatile rate. The device for analyzing results is suitable for determining whether the result of diastolic or systolic blood pressure continuously decreases or increases, and whether the result of pulsation rate decreases at the same time. According to a preferred embodiment of the present invention, the device for analysis is also suitable for determining the so-called variable index and used to compare the variable index with a predetermined or predeterminable variable index limit. According to another preferred embodiment of the present invention, the device for analysis is suitable for determining whether a series of measurement results such as systolic, diastolic blood pressure, and pulsation rate are lower / higher than a predetermined or predeterminable Similarity limit 'and / or dissimilarity limit. The device according to the present invention is further provided with a device for calculating an average value or a weighted average value based on the series of measurement results.

Description of the invention () Second a to second c: meditation state detection curve. Third figure: Similarity / dissimilarity detection curve. According to the present invention, in order to measure blood pressure, multiple measurements need to be performed successively. In principle, it is performed three times, and in some cases even up to five measurements can be made to obtain diastolic blood pressure D, systolic blood pressure S, and pulse rate p. Each measurement lasts about 60 seconds. During the two measurements before and after, another 45-60 seconds pause. This is necessary because the vein must be fully restored to flow between measurements. According to medical findings, this will take at least 45 seconds. The three measurements yield a series of measurements: Dl 'D2, D3 representing the diastolic blood pressure value; S1, S2, S3 representing the systolic blood pressure value; and PI, P2, P3 representing the pulsatile rate. These values are stored in the blood pressure measuring device. After three successful measurements, the average value can be calculated (see below) and the measurement results can be analyzed. The first step is to confirm that the patient is in a timely state of meditation. To this end, confirm whether the following first condition i ·) holds: For condition i ·), the systolic blood pressure standard is: S3 < S2 — aS < Si — 2dS, (A) where dS is set to about 5mmHg. For the condition i ·), the diastolic blood pressure standard is: D3 > D2 + dD > Dl + 2dD or (β1) D3 < D2-dD < Dl- 2dD, (B2) where dD is set to about 3 [mmHg] for condition i ·), The beat rate standard is ·· (Please read the precautions on the back before filling this page)

When the patient is not When in a meditation state, the change in pulsation rate will gradually decrease with time. For this reason, dPl is set higher than dP2. If any of the systolic blood pressure standard (A), diastolic blood pressure standard (B1) or (B2), And the pulsatility rate standard (C) was established at the same time, and the patient was determined not to be in a timely state of relaxation. In the state of insufficient relaxation, the performance of systolic blood pressure, diastolic blood pressure, and pulsation rate are shown schematically in the second a From the second graph to the second c. According to the second graph from the second a, the systolic blood pressure value continues to decrease from the first to the third measurement results. The successive blood pressure values S1 and S2, and the difference between% and S3 are higher than the parameter dS. Figure 2b shows the performance of diastolic blood pressure if the patient does not relax to the meditation state in a timely manner. In this case, with three measurements, the diastolic blood pressure usually increases steadily toward a steady-state value. Figure b, the values of di, and D3 increase steadily The differences between D2 and D1, and between D3 and D2 are higher than the predetermined limit of the variable dD. In some cases, patients who do not relax in time, their diastolic blood pressure values will decrease towards a steady-state value D3 氺. In this case, D1 * is higher than 卯 氺, and the latter is south of D3 氺. Two conditions can be seen in those who are not relaxed in time. The second C chart shows the change in pulse rate of patients who are still not in time for meditation 11 paper scale Applicable to China National Standard (CNS) A4 specification (210 X 297 mm) ----------------- (Please read the precautions on the back before filling this page) 1J.-≫ * 0-line 552127 297 mm) A7 V. Description of the invention (忒 The pulse rate value decreases toward a steady state value. Successive measurement results ρ, P2 and P2, P3 are higher than the predetermined limit dp. If The condition shown in the second a or the figure is true, and the second. The condition shown in the figure is true, it can be concluded that the patient did not relax in a timely manner. The offending patient / user was informed of this situation and was suggested After the purposeful meditation, perform the measurement step again. In another step, confirm the measurement by condition ii ·) Whether the results showed signs of distortion in blood pressure stability. For this purpose, a variable exponential yoke is applied to the diastolic, systolic blood pressure, and pulsation rate according to the following formula: ^ _ 1V1 ~ mean | n mean where mean = 坌 ΜΜ η and Ri is the measurement result Di , D2, D3, and SI, S2 S3 ', and pi, P2, P3. The Variable Index VI describes the standard deviation of the pairwise results in the measurement sequence and is independent of the number of measurements. For example, if the systolic blood pressure values are sl = 112_Hg, S2 = 124mmHg, and S3 = 124mmHg, the average is calculated as follows:

Mean = (112 + 124 + 124) / 3 = 120_Hg In this example, the variable index of systolic blood pressure is then calculated as follows:

Vis = ^ (120-112 + 124-120 + 124-20) /120=16/120=4..4% If the variable index is higher than the variable index limit, inform the user by displaying this situation / patient. If the variable index frequently exceeds a predetermined limit, it is recommended that the user (manual operation) make further diagnosis. These variable indexes are typically as follows: · For systolic blood pressure: 10 [0 / 〇] 12 (CNS) A4 (21〇T? (Please read the note on the back 3 before filling out this page) · 552127 A7 _B7___ 5. Explanation of the invention (), for diastolic blood pressure is .10 [%], and for pulsatility rate is .8 [%]. (Please read the precautions on the back before filling this page) Calculate the average of the measurement results Before, confirm whether the continuous blood pressure values are similar to each other, that is, confirm whether the following conditions iii.) Are true: For systolic blood pressure, condition iii is: S1-18mmHg < S2 < Sl + 18mmHg S2-18mmHg < S3 < S2 + 18mmHg For diastolic blood pressure, condition iii is: D1 -12mmHg < D2 < Dl + 12mmHg D2-12mmHg < D3 < D2 + 12mmHg If all the above conditions are true, the conclusion is that the measurement result is correct. Therefore, the standard arithmetic average of the measurement results is as follows: S = (Sl + S2 + S3) / 3 D = (Dl + D2 + D3) / 3 The values S and D are displayed on the blood pressure measurement device one after the other. _Line · The above range (+/- 18nnnHg and +/- 12minHg) is called the limit of similarity. It has been found that the similarity limit of systolic blood pressure +/- 18mmHg and the similarity limit of diastolic blood pressure +/- 12mmHg can be obtained with sufficient accuracy. Other similarity limits can also be used. In addition, confirm whether condition iv.) Is satisfied. Check whether the results are different from each other. The condition iv.) Is defined as follows: systolic blood pressure:

Sl + 40mmHg < S2 < S1 -40mmHg S2 + 40_Hg < S3 < S2-4〇_Hg 13 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 552127 A7 _B7___ V. Description of the invention () Diastolic blood pressure:

Dl + 25mmHg < D2 < Dl-25mmHg (Please read the precautions on the back before filling out this page) D2 + 25mmHg < D3 < D2-25mmHg If at least one of the above four conditions is met, it is concluded that at least one of the measurement results comes from False test. For systolic blood pressure of +/- 40mmHg and for diastolic blood pressure of +/- 25mmHg, this range is called the limit of dissimilarity. One can boldly assume that a measurement that exceeds the limit of dissimilarity represents a threshold value. These results are not used. If the above condition i v.) Does not hold ^ That is, if all the results are not different and the above condition iii.) Does not hold, that is, the results are not sufficiently similar to each other, then a weighted average is obtained. It is assumed that blood pressure measurements that are neither similar nor distinctive reflect a threshold or a severe pathological blood pressure variation. Therefore, the following formula is used to calculate the weighted average to reduce the impact of these values: S = 2Sl + 2S2 + S3 / 5 where S3 is a non-similar value and D = 2Dl + 2D2 + D3 / 5 where D3 is a non-similar value . A more general formula is: A1S1 + A2S2 + A3S3 A1 + A2 + A3 ^ B1D1 + 2D2 + Ugly 3D3 B1 + 52 + 53 where A1 >A3; A2 > A3 if S3 is not similar to S1 and S2, and B1 >B3; B2 > B3 If D3 is not similar to D1 and D2.

The values of Al, A2, A3 and Bl, B2, and B3 are determined empirically, and are set to 2 for similar values (such as S1 and S2) and 1 for non-similar values. Where there are further findings in the study, the Chinese paper standard (CNS) A4 (210 X 297 mm) can be applied to these 14 paper sizes. 552127 A7 5. Description of the invention (factors are modified without departing from the scope of the invention. In the third figure, the figure shows the most likely reason for the special blood pressure difference during the measurement of the # series. The curve 1 represents the probability of measuring the physiological blood pressure difference. Due to physiological reasons, the small difference in blood pressure More often. If the difference is within the range defined by similarity, that is, the condition iu), the standard arithmetic mean can be obtained. -Generally speaking, among those who are in a state of meditation, the difference in physiological blood pressure is small. The large continuous blood pressure difference, which exceeds the limit of dissimilarity, that is, the establishment condition iv), is most likely due to the stratum value. The probability of chip value is shown in curve 3 of the third figure. When the measurement result is in Article #iv.), After referring to the high disparity standard, the average value is not calculated and the equivalent value is rejected. If neither of conditions iii ·) and iv ·) holds, that is, if the measurement result is higher than the similarity limit but lower than the dissimilarity limit, the difference may be due to a pathological cause or a threshold value. The probability of blood a difference due to pathological reasons is shown in curve 2 in the second figure. In this case, a weighted average is calculated. ^ This similarity limit is set to 18 mmHg for systolic blood pressure and 12 mmHg for diastolic blood pressure. The anisotropy limit is set to 40 mmHg for systolic blood pressure and 25 mmHg for diastolic blood pressure. If one measurement is rejected, the fourth measurement is started.
