Description of the invention: [Technical field to which the invention pertains] - The present invention relates to a home-type pulse wave detection system and a detection method thereof, and more particularly to a pulse wave data of any two ends of an individual capable of simultaneously sampling and living. Measure and judge the state of the pulse wave. [Prior Art] According to how to prevent and evaluate arteriosclerosis, it is an important issue that modern people cannot neglect. The conventional arteriosclerosis measuring instrument uses a pressure sensor to capture the artery. The signal or the ultrasonic sensor is used to capture the signal, but this method is susceptible to waveform distortion caused by the hand fiber interference. At present, non-invasive arteriosclerosis measuring instruments commonly used in large hospitals in Taiwan generally have one of the following points, such as: 1. Artificial pulsed pulse: it is easier to receive external interference, and Humans, due to the action of the central nervous system, sympathetic nerves, and parasympathetic nerves, produce less fibrillation of the fibrotic fibers and are prone to waveform distortion. (2) Need ECG positioning: However, if the position of the electrode patch is not trained, it is difficult to find the correct position, and the measurement of the heart and the electrogram must be applied to the V-poor, the measurement is very Time consuming and inconvenient. Grain (n-synchronous current model only uses - group sensor volume wave t slave to make pulse wave speed (Pulse Wave Vel_ race, by = type must first measure the upper limb signal, then measure the lower limbs to call no lower limb bribes is not The pulse wave emitted by the same dirty stroke is therefore to be considered. The price of the instrument is not affordable to the family. If it is necessary, the concept of arteriosclerosis detection is extended to the family. _(4)_ Home = mechanism of ' ' 'but its measurement method is not the current medical circle sst = puise wave vei 〇 city, pwv), but the use of the pulse of the skin vibration hardening, the volume of the result is accurate The correlation of 1259073 is a matter of consideration. As mentioned above, the above-mentioned measuring device does not provide a kind of health demand, so it is used for a low-cost, high-precision tooth.

In the transport, and processing, with the purpose 'The invention includes: a plurality of health wave signals to capture the skirt, for stepping to capture one At least one first portion and a 3-wave data on the living individual; the -th processing circuit 'for converting the aforementioned & poor material' into digital pulse signal data; a second processing circuit The digital pulse signal data includes: performing __ feature point finding and = speed calculation; and a display device for displaying the detection result. / According to the present invention, the nano wave device is taken The pulse signal is used to greatly reduce the cost. According to another aspect of the present invention, the pulse signal acquisition device is configured to optically capture a volumetric wave signal capture clip to simultaneously locate one of the two parts of the living individual. For the purpose of making the above-mentioned objects, features and advantages of the present invention more obvious, the preferred embodiments of the present invention, together with the description, are described in detail below. Way] Please Referring to Figures, there is shown a system architecture diagram of a pulse wave detection system 1 exaggerated in accordance with a preferred embodiment of the present invention, the system comprising:
複數個脈波峨娜裝i 1G，用1顶步擷取—活的個體 (諸如.一心職具有鼓動狀態之人）上之至少一第一部位D 1259073 (諸如：手指，fmger)與一第二部位14 (諸如：腳趾，t〇e)之 脈波貧料（如第二圖所示），其中，該第一部位12盥第二部位 14之脈波資料係不同位置。在本實施例中，該脈^訊號娜 裝置10係設有兩個，其採用相同之紅外線感應裝置，如使用 Nellcor公司所生產的型號DS_1〇〇A機構搭配Ute〇N公司生 產的紅外線發射裝置型號LTE3G2與紅外線感應裝置型號 LTR309，而透過雙通道感應裝置同步讀取前述第一、二部位 12、14包含手指及腳趾之脈波資料。該雙通韻應裝置係可 利用兩條光容積波訊號擷取夾，以同步擷取資料。 二第-處理電路20，諸如採用—微處理器電路，如採用 德州儀器公司(Texas Instrument, TI)生產的型號Msp43〇F149 作為本系統核心，其主要負責整體系統動作，用以將前述所顧 取之該，類比脈波資料，轉換成為數位脈波訊號資料。 了第二處理電路30，諸如剌—數位峨處理器(卿加 SignalProcessc^DSp)，用以處理前述之第一處理電路⑼之該 2脈波訊號·，讀理分析魏錄波域的特徵點包括 、點及主波峰（请配合參照第二圖），而根據於該活的^^固體 上之任二檢測位置之距離（諸如前述之第一部位12與第二部 二14間之距離）而除以前述該數位脈波訊號的特徵^，包“ ί二二部f 12、14兩脈波起博點間之時間差，或兩脈波之 ^峰間之時間差’而可計算出該脈波傳導速度㈣兄 ^吻，PWV)。更進一步地說，由於脈波是因為心臟搏動所 |起的波傳導現象，除了因為心臟的收縮與舒張所引起 =十ίίίΐ壓力在2中傳導的反彈波、管壁内的散射波與 象而動脈硬化會導至血液流速與脈 ^傳¥速度增加’且雜脈波的波形會延著祕血管傳佈全 ^ ’因此，擷取不_位脈波並利畴徵點定位，即可導出脈 疫傅導速度。 起搏點是整個脈波外形的起始點’代表心臟收縮開始，大 6 1259073 里血液流入動脈的起始點，血管内容積與血流量突然快速擴 ，，造成脈波急遽上升至主波峰的現象；而脈波最低點則通 於重搏波頂點至下一週期的起搏點之間，反映了心臟於 ，容性，縮時期血管内少量的容積與血流量。因此本發明計 异脈波最低點至主波峰頂點的二階微分，如（丨）式所示，經 由二階微分後的最大值便可定位出此段脈波瞬間變化率最 的位置，此位置即為起搏點。 凡[”]=羞:〜]----------------(1)A plurality of pulse waves are loaded with i 1G, and one step is taken - at least one first part D 1259073 (such as: finger, fmger) and one on the living individual (such as a person with a motivated state) The pulse wave of the second portion 14 (such as the toe, t〇e) is as shown in the second figure, wherein the pulse data of the second portion 14 of the first portion 12 is different. In this embodiment, the pulse signal device 10 is provided with two the same infrared sensing device, such as the model DS_1〇〇A manufactured by Nellcor Co., Ltd., and the infrared emitting device manufactured by Ute〇N. The model LTE3G2 and the infrared sensing device model LTR309, and the first and second portions 12 and 14 including the pulse wave data of the finger and the toe are synchronously read by the two-channel sensing device. The dual-pass rhyme device can utilize two optical volume wave signal capture clips to simultaneously capture data. The second-processing circuit 20, such as a microprocessor circuit, such as the model Msp43〇F149 manufactured by Texas Instruments (TI), is the core of the system, and is mainly responsible for the overall system operation for the aforementioned In this case, the analog pulse data is converted into digital pulse signal data. a second processing circuit 30, such as a digital-digital processor (Singapore Plus SignalProcessc^DSp), for processing the 2-pulse signal of the first processing circuit (9), and reading the feature points of the Wei-recording domain, Point and main peak (please refer to the second figure), and according to the distance of any two detection positions on the living solid (such as the distance between the first portion 12 and the second portion 14) The pulse wave conduction can be calculated by the feature of the digital pulse wave signal described above, including the time difference between the two pulse points of the two pulses f 12 and 14 or the time difference between the peaks of the two pulse waves. Speed (four) brother ^ kiss, PWV). Further, because the pulse wave is caused by the heart beat, the wave conduction phenomenon, except for the contraction and relaxation caused by the heart = 10ίίίί pressure, the rebound wave transmitted in 2, The scattered waves in the wall of the tube and the hardening of the arteries will lead to the increase of the blood flow rate and the velocity of the pulse. The waveform of the pulse will spread across the sacral blood vessels. Therefore, it is not possible to extract the pulse wave. The location of the domain points can be used to derive the pulse-guided velocity. The starting point of the whole pulse shape represents the beginning of systole, the blood inflow into the artery at 6 1259073, the blood vessel volume and blood flow suddenly expand rapidly, causing the pulse wave to rise sharply to the main peak; The lowest point of the wave passes between the apex of the re-pulsation wave and the pacing point of the next cycle, reflecting a small volume and blood flow in the blood vessel of the heart, capacitive, and contraction period. Therefore, the lowest point of the differential pulse of the present invention is The second-order differential of the apex of the main peak, as shown by (丨), can locate the position of the instantaneous rate of change of the pulse wave through the maximum value after the second-order differentiation. This position is the pacing point. Where ["] = Shame: ~]----------------(1)
