Description of the Invention: [Technical Field] The present invention relates to a blood sample measuring method, and more particularly to a voltage-time variation waveform of blood pressure pulsation which can be disturbed by external vibration when the amount of shame is applied. The method of subtracting the interference variation waveform obtained by the conversion function to restore the voltage-time-varying waveform without vibration interference and measuring the correct blood pressure value. [Prior Art] According to the 'normal sphygmomanometer', it is divided into traditional mercury and electronic, in which the mercury sphygmomanometer is not only time-consuming, but also requires professional training and experience, so that you can measure the correct blood pressure, electronic blood table The upper type, the wrist type, the finger type, the finger type, etc., because the electronic blood dust does not need to be the work of the slave, and the measurement result is displayed on the display, so that the subject is very t-existing in the use. Although there is the above convenience; but because of the well-known measurement results of blood dust, not only with the second car, for example, the blood pressure is usually lower in the morning, but the blood pressure at noon is higher. According to the record of the remaining money (four), the financial model of the market = the case / sales system is to raise the amount of the sphygmomanometer to the situation where the blood pressure of the measured piece is not accurate. [Summary of the Invention] In the case of the shortcomings of people's money in the use of shame pressure, it is aimed at the method of “wrong” and “vibration interference”. ° Again.

Then, the measured blood pressure pulsating voltage _ time change waveform is subtracted from the vibration waveform of the vibration and then the correct blood pressure value is calculated. Another object of the present invention is to provide a method for eliminating vibration interference when measuring blood pressure by a sphygmomanometer, wherein the acceleration sensor in the sphygmomanometer detects whether the vibration interference received by the blood pressure is within an allowable range, if it exceeds The allowable range will send a warning signal to remind the subject and re-measure. According to still another object of the present invention, the warning signal is displayed through a display device (which may be an LCD display screen, an LED light number) or a broadcaster, such as voice, music, sound, various color sentences, text, lights, or graphics. . [Embodiment] Please refer to FIG. 2, which is a method for eliminating vibration interference when measuring a pressure. The sphygmomanometer is mainly used by the pressure sensor 10' to accelerate the sensor 20, The warning unit 3〇 and the measuring circuit 40 are composed, and the pressure sensor 1〇, the acceleration sensor 2〇, the warning unit 3〇 and the measuring circuit 40 respectively (the blood pressure is the same as the measuring circuit system) The measuring circuit is the same, so the structure is not described in detail here; the φ the pressure sensor 1()' is a waveform of the voltage between the side-b temples by the pressure difference of the blood pressure pulsation; In the embodiment, the acceleration sensor 2G′ generates an acceleration _ crystal of different voltage changes when the spatial position changes, and then measures the time variation waveform of the device and the interference voltage (but is familiar with the skill artist, still It can be implemented by other components, for example, the accelerator is a two-dimensional space changeer for the debt measurement or the three-dimensional space change can be detected; the warning unit 30' can be an LCD display screen, an LED signal or a broadcaster, etc. The vibration interference caused by the measurement of the subject exceeds the allowable range When the voice, music, sound, various colors of light, graphics or text, etc., to remind the subject; 丄 to 6592, the measuring circuit 40, is received by the pressure sensor 10, the acceleration sensor 20 The voltage-time change waveform is calculated and calculated; ^The mouth is shown in Figures 1, 2, 4 and 4A (this embodiment is a wrist-type electronic sphygmomanometer as an example) 'Related to the technical content, features and effects of the present invention The following steps can be clearly presented; Step S01: Turn on the sphygmomanometer to perform the blood pressure measurement function; Step S02: The sphygmomanometer acceleration sensor 2 detects whether the vibration interference is within the allowable range, beyond the range of the valley If the step is not exceeded, the step S04 is executed; Step S03: the warning unit 30 sends a warning signal to remind the subject, and the step S02 is re-executed (the warning signal in the embodiment) It can be voice, music, sound, various colors of light, graphics or text, etc., the display device can be LQ) display screen, LED display screen, light or speaker, etc.; Step S04: respectively detect pressure sensor 1 And accelerating the voltage _time change waveform of the sensor 2 并 and performing step S05; step S05: detecting the voltage _ time change waveform of the acceleration sensor 2Q subjected to the vibration interference according to the conversion function, calculating the interference waveform change, And performing step s〇6; Step S〇6: subtracting the voltage-time variation waveform of the blood pressure pulse detected by the vibration interference from the interference waveform change, and performing step s〇7; Step S07: subtracting the interference waveform The blood pressure pulsation voltage _ time change waveform is changed, and the correct blood pressure value is calculated. The following is a method for calculating the conversion function in step S05. Please refer to FIG. 3, which is an example of a wrist sphygmomanometer. The sphygmomanometer is equipped with a pressure sensor, an accelerometer, and an airbag bag that is attached to the wrist of the human body. At this time, the blood pressure is used as a dummy to measure, and when the measurement is made, the pressure gauge is vibrated. The voltage and time change waveform of the pressure sensor after the airbag bag is inflated and vibrated, and the voltage generated by the sphygmomanometer to the vibration in the acceleration sense _Time change The waveform is measured; after the measurement, the upper part of the figure is the fine _ time-varying waveform of the accelerating device when the vibration is vibrated, and the lower part is the voltage detected by the interference of the 13265592 force sensor in the vibration- Time-varying waveform; carefully observe the waveforms of the upper and the dam, and find that the number of cycles is the same, and there is a corresponding relationship between the pressure sensor and the voltage detected by the acceleration sensor, that is, the pressure sensor The detected voltage (ie, the change in the interference waveform that is simply disturbed by the vibration) can be obtained by multiplying the voltage detected by the acceleration sensor by a statistically summarized conversion function (such as F(At) below). Therefore, statistically, a corresponding mathematical function relationship can be used to explain the method of eliminating vibration interference, as follows: P" (At )= P(At)+G(At)*F(At) where P”(△〇-- In order to measure the voltage-time change waveform detected by the pressure sensor, it contains the voltage-time variation waveform of blood pressure and vibration interference; P(At)--in the ideal state, when it is not subjected to vibration, Pressure sensor detects the voltage-time change of human blood pressure pulsation Waveform; G(ZVt)--the voltage _ time-varying waveform for accelerating the vibration of the sensor at the same time; F(Z\t)- is the transfer function in the above environment, which will be detected by the accelerating sensor The voltage multiplied by this conversion function is the interference waveform change of the pressure sensor; G(At)*F(At)—is the interference waveform change of the pressure sensor; (Δt)-- is the measurement time ( The time difference in the same time); so Ρ(Δΐ) =PM (At ) -G(At)*F(At), that is, the voltage _time change waveform of the correct unvibrated pressure sensor is equal to The voltage-time variation waveform that is disturbed by the vibration subtracts the product of the conversion function and the voltage-time-varying waveform detected by the acceleration sensor. In summary, the method of the present invention belongs to the first invention, and the method of the present invention can be applied to various types of electronic sphygmomanometers, including a desktop type, a wrist type, a tunnel type, a finger type, and the like. The invention is based on the changes and modifications of the book, which are still covered by the patent of the present invention.
