Description of the Invention: [Technical Field] [0001] The present invention relates to a multi-point photoelectric measuring device for acquiring body surface microcirculation information and an apparatus thereof, and more particularly to an array arrangement of fast switching The optical transmitter and the optical receiver sequentially transmit and receive infrared light signals of different wavelengths, and perform a micro-circulation measurement device for the surface area of the human body surface by means of a time-division multi-point detection method. [Previous technology] [0002] In recent years, the proportion of people suffering from diabetes is getting higher and higher, and related medical care is also becoming increasingly important. Especially diabetes is a chronic disease that requires long-term recovery of physical condition. In the early stage of the disease (peripheral vascular disease, PVD), some symptoms will first appear in the human microcirculation system, resulting in abnormal microcirculation function. For example, when the patient's peripheral microcirculatory condition deteriorates, it may cause infection or septic symptoms of the peripheral tissue, and even cause amputation or death in severe cases. It is not easy for the patient to master the slight circulation of the end, and the patient is often accompanied by sympathetic and parasympathetic disorders, resulting in a slight abnormality or dullness of the extremities, and it is easier to neglect the relevant infection symptoms. In order to enable the diabetic patients to self-examine or enable the medical staff to quickly detect the patient's slight circulation at the end, the infrared light of different wavelengths is irradiated to the human body, and the absorption of the infrared light by the human tissue is different, and the reflected optical signal is analyzed. After comparing with the reflected light signal value of the normal human body, it is judged whether the microcirculation of the peripheral tissue of the patient has a lesion or even a lesion degree, and the method is a non-invasive test, which does not cause discomfort to the patient. Feelings; for example, the Republic of China Invention Patent Bulletin No. 41 8081 "Non-invasive oximeter and its detection method and waveform 099128126 Form No. A0101 Page 4 of 21 0992049466-0 201208648 Signal peak wave valley detection method The detection probe emits a first wavelength light source and a second wavelength light source, and then respectively extracts the two wavelength light sources to illuminate the subject, and converts them into a first telecommunications corresponding to the subject's gold oxygen concentration. No. and the second electrical signal, and analyzed and processed; and, as in the Republic of China Invention Patent Notice No. 1298630, "with variable structure a blood physiological signal sensing device having a first housing containing a light emitting element and a light receiving element, and a second housing electrically connected to the first housing and containing the blood physiology At least a portion of the circuit components required by the signal sensing device sense physiological signals by changes in the absorbance of light to the light. However, most of the above-mentioned patents and past studies are only for single-point measurement of the affected part, so the slightly cyclical evaluation of the end is quite subjective. In particular, this method has great differences in different measurement positions. For patients without measurement experience, After repeated training, the correct data can be measured.

Diabetes in patients with macrovascular disease, can lead to vascular atherosclerosis progress faster than the average person, easily lead to vascular stenosis and obstruction, resulting in reduced blood flow and slow flow. Taking the foot as an example; the urethral disease occurs in the radial artery of the lower extremities of both sides, the radial artery, the arteriolar venous artery, and is blocked by a multi-segment. If the large blood vessel is blocked, the terminal vascular circulation is poor. Lead to ischemia of the foot, easy to cause foot ulcers and tissue necrosis. Through this system, the volume change of the patient's blood vessels can be monitored, and then the changes in blood volume and flow rate in the blood vessel can be estimated. As a judgment of the health status of the peripheral microcirculation, i can provide a simple and portable portable system. It can be used for self-monitoring and care, and with multiple light emitters, multiple detections can be performed at the same time to reduce the probability of detection omission. 099128126 Further Form No. A〇l〇i The light emitters are arranged in at least one array, and the number of the 6th/21st page 0992049466-0 201208648 light receivers is the same as the number of light emitter arrays, and Any optical receiver is disposed in the center of the array of optical transmitters to which it belongs, and any one of the optical receivers is at the same distance from any of the optical transmitters of the array to which it belongs. Thus, the optical receivers can receive according to a specific ratio. The light emitters emit reflected light from the infrared light, which enables a more complete and accurate detection of the detection. Ο Further, a cardiometer is electrically connected to the processing unit', and the processing unit generates a light volume change description waveform (PPG) according to the digital signal processing generated by the core controller, and the cardiac power measurement In the instrument, an ECG signal is generated. (ECG): 'v The processing unit further defines the PTTp index, the PTTf index, and the characteristic parameter of the Amp ratio index from the light volume change description waveform and the electrocardiogram signal as the auxiliary PPG waveform. The basis of the quantization parameter is captured, and the comparison picture stored in the processing unit is compared, and the detection picture is output. The main effects of this creation are: Ο [0004] By quickly switching the array of light emitters, multi-point measurement can be performed on the microcirculation of human body tissue, which is more accurate and can be improved because of single-point measurement. The way, while the detection produces a missing defect. [Embodiment] In synthesizing the above technical features, the main effects of the present invention will be clearly shown in the following embodiments. 099128126 The structure and use of the device and device of the present invention are respectively shown in the first figure and the second figure. The device and device of the present invention comprise an optical signal transceiver unit (1), a core controller (2), and a device. Switch (3), a receiving circuit (4), a signal switcher (5), a filter amplifier circuit (6) - a processing unit (7), a display (8) and a heart rate form number A0101 page 7 / 21 pages 0992049466 -0 201208648 Measurer (9). The optical signal transceiver unit (1) is provided with a plurality of light emitters (11) and at least one light receiver (11), and the light emitters (11) are infrared light having an emission wavelength of 6 60 nm to 94 0 nm. The light source is arranged in at least one of an array, and the optical receiver (12) is just received 1C for receiving reflected light having a wavelength of 500 nm to 700 nm, and is located at the center of the array of the light emitters (11). And any one of the light receivers (12) is at the same distance from any one of the light emitters (11) of the array, so that the light receivers (12) can receive the infrared emitted by the light emitters (11) according to a specific ratio. The reflected light of light [please refer to the third and fourth figures], the more the number of the light emitters (11) and the light receivers (12) are formed, and the more arrays are formed, the more the range that can be measured Large, the more accurate the measured data. In use, the core controller (2) controls the switch (3) to quickly switch the light emitters (11) at a speed of ΙΟΟΚΗζ to sequentially emit a wavelength of about 66〇ni to 940nm toward the human body (A). Infrared light, 099128126 and the core controller (2) uses the PIC321X675F512L single chip to reflect the reflected light of different wavelengths through the characteristic light absorption characteristics of different components of the microvessels (b) in the human skin (A) peripheral skin group. The principle can be roughly explained as follows. When a part of the infrared photons are irradiated to the stationary tissues of the skin and the surface of the microvessels (B), the reflected photons do not have a Doppler shift effect, and the other part of the infrared light. When photons are irradiated to the red blood cells (B1) moving in the microvessels (β) in the microcirculation, the frequency of the scattered infrared light will be frequency-shifted due to the influence of the particle velocity of the red blood cells (B1) [see the fifth figure]. After the reflected light is received by the optical receiver (12), the optical signal 0992049466-0 A0101 page 8/21 page 201208648 is converted into a telecommunication signal through the receiving circuit (4). The wavelength of the reflected light of different components is different, and the core controller (2) controls the signal switcher (5) to classify the electrical signal according to the wavelength of the reflected light, and then appropriately enlarges the signal through the filtering and amplifying circuit (6). After the electrical signal, the wheel controller is turned into the core controller (2). The core controller (2) converts the electrical signal into a digital signal and inputs it to the processing unit (7), thereby obtaining a description of the light volume change. Waveform [PPG], in addition, 'reuse the cardiometer (9) to generate an ECG signal [ECG], the processing unit (7) further defines PTTp index, PTT.fi曰仏 and Amp by PPG and ECG The characteristic parameter of the ratio indicator is used as the basis for the auxiliary PPG waveform to obtain the quantization parameter, and the processing unit (7) compares the characteristic parameters with the normal human body (A) to compare the parameters [see the sixth figure]. It is a schematic diagram of the synchronization of the ECG signal and the PPG. The left side of the figure is the normal human ECG waveform and the left and right toe PPG waveform diagram. The right side is the unilateral lower limb with PVD patient waveform, which defines the ECG waveform. R~peak to ρρς waveform The time difference between the highest point is the PTTp index · The time difference between the R_peak of the ECG wave and the lowest point of the PPG waveform is the PTTf index; the ratio of the first large wave amplitude to the second wavelet amplitude of the PPG waveform is the Amp ratio index, by defining these characteristic parameters In the human limbs surface microcirculation assessment, such as the foot microcirculation, has a good evaluation value and significance. The display (8) outputs a comparison detection screen for the user to observe whether the detection area is normal or produces an infected lesion' because the light emitters (11) drive the light source into the skin tissue and receive in a preset order. Reflected infrared light signals, thereby measuring the tissue circulation of different spatial segments' without driving all light emitters (11) at the same time, that is, using fast switching to achieve regional multi-channel measurement [see seventh Figure ' is a schematic diagram of the waveforms of each of the light emitters (099128126 Form No. A0101, page 9/21 pages 0992049466-0 201208648 11), which are rapidly switched according to a specific frequency. The uppermost layer of the figure shows that the light emitters (11) emit infrared light. The frequency of the light, the peak indicates the state of turning on any of the light emitters (11); the second layer, the third layer and the fourth layer in the figure sequentially represent each of the light emitters (11), and the peaks show Turn on the state of emitting infrared light, thereby quickly switching the light emitters (11) to sequentially emit infrared light], there will be some micro-reception time difference in the process, but under high-speed switching, it can still be regarded as the same The step signal is taken to reflect the current cycle condition of the affected part. Since the light emitters (11) are arranged in an array, multi-point measurement can be performed on the microcirculation of the human body (A), and the measurement is more accurate, which can improve the single-point measurement method and detect At the same time, the reflected light and light signals are also arrayed. When the final image is formed, a two-dimensional detection image can be presented for the user to observe, and the application can be used for clinical tumor diagnosis and Chinese medicine pulse image. Analysis, brain blood volume and blood oxygen distribution image analysis and other widely used, for example, when applied to the detection of diabetic patients, because diabetes is a chronic disease, patients often need to be fixed to and from the hospital for treatment, but some unnecessary examinations However, it often takes a lot of time for patients. When patients use this home monitoring system, they can systematically analyze and record the physiological signals of their feet and feet, in addition to allowing patients to get their own foot microcirculation every day. In addition, the data can be transmitted to the doctor through the Internet for objective judgment, avoiding the pain of the boat, often going back and forth to the hospital, and reaching early detection. The effect of treatment. BRIEF DESCRIPTION OF THE DRAWINGS [0005] The first figure is a schematic diagram of the structure of the device and device of the present invention.
