New Description: [New Technology Field] This creation department is about a blood pressure pulse wave extraction and parameter analysis system device, especially a high-sensitivity pressure sensitive element in contact with the front end device of pressure application. A blood pressure analysis system device for analyzing a variety of waveform parameters. [Prior Art] In the development of the instrument, it is usually used to study the pulse, pulse and wave. In the hardware design, the pressure transducer, condenser microphone and strain gauge are mainly used. Or the relevant sensor, take the position of the wrist, the off, the ruler, and measure the balance of the float, the middle, and the sinker. The obtained amount is measured by the Qualcomm _ Qualcomm and the low pass filter, and then the analogy After the digital signal is transferred to the computer, the pulse wave of the computer is finally analyzed and compared with the pulse wave in the database to judge the patient's pulse. In the past few dozens, there are new scholars at home and abroad who are engaged in the research of pulse wave. For example, the early research and development of the nine scholars of the Chinese Medical College, the uncle of the New York, since 1977, engaged in the study of pulse wave shape analysis, grain - Set the pulse wave _ judgment standard, and use this to understand the condition of the human body. In the early research of Professor Zhu, the application of multi-channel recorder and self-made pressure conversion to '1 measured 25 surface wave waveform, and in recent years, with the rapid change of computer technology, the research of pulse diagnosis instrument also Update. In the fine years of China Medical University, Cai Yunning, Liu Dingming and other scholars have made a series of improvements and research on the pulse diagnosis instrument. Their research content is mainly the machine, the test pulse, the purpose of the pulse, and the acquisition of the pulse. In the pulse diagnosis site to enter the sputum (four) I and the study 'also makes the school money to rely on the pre-stress and displacement of the way to find a better positioning point. /, 5 .M325098 In recent years, in the study of pulse diagnosis, there are many software and hardware devices that use computer to write combined with pulse diagnosis, such as Professor Wang Weigong of Yangming University. In 1983, the original "Resonance Theory,", in theory It is thought that the pulse wave is the pressure wave of blood, and when it flows through the internal organs of the body, it is generated by resonance with the heart. He uses the pressure transducer to obtain the pulse wave. After analysis, the resonance wave intensity at different frequencies and the health status of different organs are found. It is related to each other and uses this theory to design a set of instruments for pulse wave research. In 1995, Lai Jianheng, a master student of Weng Qingsong Laboratory, used infrared light to analyze the finger pulse signal of high blood pressure patients. The results of the study and the identification of the end of the finger, can analyze the injury of the pulse... The spectrum analysis method discusses the spectrum power of the hypertensive patients is different from the normal human power. Then in 1996, the Department of Medical Engineering of Zhongyuan University Weng Qingsong's laboratory has developed a three-finger mechanical pulse diagnosis system and computer-aided analysis secrets, and analyzed the patients of various pulse types, aiming at the quantification of P and U angles. Line analysis, the results found that a variety of pulse waveforms can be measured and measured. ···^ Bu In 1989, 'Zhongyuan University Lai Yubin master student database technology development "pulse wave measurement and analysis of New Zealand", at the same time invented the three fingers The hardware device, followed by the graduate student of the Central University Medical Institute, Li Enzhang, under the guidance of Professor Fu Shien, developed the "mechanical finger and pulse wave analysis system, the age system is a kind of computer intelligence system, the design not only contains In addition to the analysis function, it also adds the characteristics of the m-reading, and also improves the hardware device of the three fingers. Others such as Professor Wei Lingyun of Jiaotong University also conducted related research on pulse diagnosis. He used the spectral energy ratio and matched the relationship between the inch and the viscera as the main reference index. M325098 c Compare normal pulse with abnormal pulse The spectrum of the wave changes. In 1993, the successful university, Yang Shoukun, was born in the application of single crystal microcomputer technology to develop "portable f intelligent pulse wave Wei _4 and analysis of suspicion, ... product is - 可立 portable 1 test system" research and development After the money was completed and passed the clinical experiment, it was finally put on the market. In addition, in 1998, Feng Chiu University’s Lin Qinyu New Zealand used the principle of pulse diagnosis to develop and develop a new type of sensory P material (10) pulse diagnosis (4) The multi-pulse signal system has further development in the research of pulse wave signal sensing and extraction system. • In 2005, students such as Chen Chuanzong and Wu Mingchuan of the Taipei University of Science and Technology analyzed the state of digital blood flow. The method of constructing a pulse wave analysis system and exploring its application in the pulse image has made the pulse diagnosis a major step in the research of automation technology. Therefore, in recent years, the modern development of the pulse research can be roughly Divided into pulse pressure belt, and Zhiju Lishou # two ways, although the pulse pressure belt improved type of button has the advantage of being easy to fix, but it has the measurement _ pulse wave riding wrist overall blood test, Lin single secret In the foot of the three-point pulse, and in the mechanical arm extraction interface The development of the Lai can be used to make the three-point pulse of the ruler, but there are also shortcomings of the measurement point displacement caused by the movement of the wrist. In addition, in the research of foreign scholars, KMiyak let others focus on the writing of blood ship waves. In the parallel blood vessels, _ force waves, but the direction of their analysis, usually only the blood vessels of the blood vessels, _ disease, and no more like a pulse for the internal organs of the body to make a more layered discussion, Lan master (four) research method, is fast The source of blood pressure waves analyzed after the conversion of the thorn leaves is from the invading heart to the signal directly or indirectly from the artery. The main research is focused on the pathological blood bank wave. In the spectrum, find out the parameters of the parameters to interpret various diseases. 7 • M325098 In summary, the research on the application of computer to pulse at home and abroad is mainly focused on the development of pulse (10), and in the process of development, Firstly, it emphasizes the collection and comparison of waveform samples, and cooperates with the development of various database systems for analysis. Through the continuous efforts of these scholars and experts, the scientific research of pulse diagnosis is more vague than traditional. The concept has a clearer numerical definition. However, because the main parameters and quantification of pulse wave are still not fully integrated in the current pulse diagnosis research, most of them are mainly based on single-view waveform changes, lacking main waveform feature points and _ Characteristic parameters _ take or strict statistical analysis, so the study is still relatively large, such as hypertension in the field of medicine, taking the main pulse in the main pulse wave, p wave amplitude and angle should In view of the above, the author has addressed the above-mentioned problems and solved the above-mentioned shortcomings. [New content] The main purpose of this creation is to provide a system of health-healthy blood pressure pulse devices and analysis. Including the whole hand and leg pressure belt type inspection device, and the hand-held pulse wave extraction device which can take a single point and _ inch rule, combined with the ECG pickup device which can record synchronously. So that the system can simultaneously capture the pulse signal and compare it with the ECG for comparison and diagnosis. In order to achieve the above objectives, the blood pressure pulse acquisition and analysis system device of the present invention includes: a pirate host body, and an internal instrument panel, a wave filter, a circuit board for amplifying and benefiting, etc., are arranged inside. There is also a wrist pulse pressure belt with blood pressure wave picking device, - single point pressure ° skin clothing, and - electrocardiogram Na Hang set 'these and the instrument, the host _, with blood pressure pulse wave analysis system unit, The blood pressure waveform is completely reproduced on the screen 8. M325098, and the blood pressure waveform is analyzed and extracted. The pulse pressure is transposed with blood, and the gas is pressurized by the gas motor, and then pressurized by the tube-like rubber county capsule, and the blood flow pulsation of the wrist is generated to the inflatable rubber capsule. Force, and then use a pipeline to connect to a gas force sensor' This pressure sensor converts the reaction of blood pressure fluctuations into electrical signals, and finally through analog digital conversion! The signal is digitized and transferred to a computer and converted into a text slot for recording. _ The device for single-point pressure-type pulse wave is a contact pressure sensing for 'such as strain gauge' to directly contact the pulse of the human wrist epidermis, which is generated by the pulse through the skin for the sensor The pressure wave can be converted into a signal by a pressure sensor. Finally, the signal is digitized and transmitted to a computer through an analog digital converter, and converted into a text file for recording. The device is based on the three electrode patches of Xiang-Xiang, which are placed in the left, right and left feet of the human body. The human body electrical signals are differentially amplified, filtered, and then enlarged and then amplified through the wires. An analog-to-digital converter that digitizes the signal, transmits it to a computer, and converts it into a text file for recording. , /, Zhongyu blood pressure pulse wave analysis system unit, is a computer software program to write a signal analysis software interface 'which can be a complete blood pressure secret on the screen, and analysis of the characteristics of the blood wave material line and Capture, including the coordinates of each important parameter in the blood pressure waveform, such as the main wave rise point s, the main peak peak point P, the tidal wave peak highest point T, the tidal wave start point E, the specific wave start point C, the heavy beat wave drop branch F, The end point of the pulse wave s', the slope between the points and the angle of the skin peak, the ZU of the main wave rising branch, etc., the parameter can be stored in the electric 9. M325098 brain hard disk after the extraction, in the soft interface of the analysis parameter In the design, the analysis of the pulse waveform parameters is better, and then the design of the user-operated analysis software of the LabView user can be completed. Calculate the angle angle of the p and u angles in the blood pressure wave and make all the parameters can be displayed in the interface of the 'such as the blood pressure waveform. For example, the main wave rise point s, the main peak peak point P ' The highest point of the tidal wave peak τ 'the tidal wave starting point E , the beat wave starting point c, the heavy beat wave drop branch F, the pulse end point S', and the slope and angle between the points (such as the zp of the main peak, the ZU of the main wave rising branch), etc., after the parameter is retrieved Can be stored on a computer hard drive. The system device of this creation includes the electrocardiograph (10)), the design of the Western medicine wrist pulse pressure band Na pulse wave, and the integration of the contact surface force material point. In the past, the old pulse diagnosis instrument was not able to take the parameters and analyze the parameters. In addition to the combination of single point, pulse pressure belt and other two types of diagnosis, and at the pressure front end The device's new contact-type high-sensitivity pressure-sensing element (Kyowa PSM_1KAB) makes it possible to contact the Lu-shaped pulse wave to capture the blood pressure wave signal with high sensitivity. The purpose of the present invention, the technical content, the features, and the effects achieved by the present invention will be more readily understood by the following detailed description of the preferred embodiments. [Embodiment] Please refer to the first figure. In the process of taking the pulse wave, it is often necessary to use a variety of different pressures to understand the difference between the waveform of the brachial artery under different external force and the signal source.

In addition, please refer to the sixth and seventh figures, the pulse pressure belt of the radial artery pulse wave extraction device 12, mainly the devil thief cloth surface 18, the devil silk matte surface 19, the soft rubber inflatable capsule 2 〇, the plastic enamel outer coating The fabric surface 21 is connected to the domain domain body 9 via the trunking and twisting assembly 22. The radial artery pulse wave extraction device 12 is mainly based on a gas pressure sensor (Mps 2〇〇) combined with a traditional wrist pulse pressure belt to extract blood pressure waves from the wrist, the principle is similar to the measurement of the traditional pulse pressure belt. The blood pressure signal is measured by a series of amplification and filtering circuits to measure the blood pressure signal generated by the human body. The pulse pressure band blood pressure wave picking device is a __ marriage air motor to pressurize the gas, and pressurizes the rubber bag through the official line to force the blood flow pulsation of the wrist to generate the inflatable rubber skin capsule - The reaction force is then connected to a gas pressure sense by means of a pipeline. The pressure sensor converts the reaction force of the blood pressure fluctuation into an electrical signal. Finally, the signal is digitized and transmitted to the computer through an analog digital converter, and converted. Record in a text file. In addition, in the design of the lead II electrocardiogram and brain wave diagram, please refer to the fourth figure, which is to use the electrocardiogram to extract silver chloride (AgCl) adhesive sensor (sens〇r)10, such as As shown in the figure of the 12th M325098, the physiological weak electrical signal is also recorded through the 漪 series amplification filter circuit 7 after the 'input signal transmission interface card (DAQ card) 4. The system of this creation experiment drives the instrumentation amplifier (INA118) and the amplification filter circuit (OP741) with a stable input voltage of ±12 volts (V), and transmits the signal to the signal transmission interface card 4 to analogize the digital signal. Finally, through the software operation, the signal is sorted and collected, and recorded into a text file type (TXT), so that the waveform of the recording slot can be displayed at any time or signal analysis can be performed for other analysis software. The architecture of the overall system is based on the ability to expand the physiological signal input to integrate any physiological signals needed at any time. The electrocardiograph device uses a three-electrode patch and places it on the left, right and left feet of the human body. The human body electrical signal is differentially amplified, filtered, and amplified by the electric wire through an analog digital converter. The signal is digitized and transferred to the computer and converted to a text file for recording. The blood pressure pulse wave analysis system unit is a computer software program that composes a signal analysis software interface, which can completely reproduce the blood pressure waveform on the computer screen, and analyze and extract the characteristic parameters of the blood pressure waveform.
