Description of the Invention: [Technical Field of the Invention] The present invention relates to a self-health detecting device, and more particularly to a computer system that non-invasively extracts physiological information. [Prior Art] In view of the continuous advancement of health care technology such as medical equipment and health foods in recent years, the average life expectancy of Chinese people has increased; however, in fact, the death population has increased. In response to the Department of Health's statistics on the top ten causes of death: malignant tumors, cerebrovascular diseases, heart disease, high blood pressure, etc., most of them cannot be screened out from health care payments. The reason for this is that the Chinese people are not active in health checkups, and the health check-ups for the whole people's health insurance are limited to - such as blood draw, urine test (4) intrusive investigation, as for non-invasive inspection of Weiben. Higher projects, such as: ultrasonic, twilight and electrocardiogram, are not in the payment project; in addition, due to the inspection items of ultrasound, X-ray and electrocardiogram (4) and need to be scheduled, it is not Convenience. There are health check-up devices available for purchase by the Chinese people on the face == A portable blood gas concentration meter 10, which is based on non-invasive inspection methods, and relies on physiological information, values and blood waves _, for the morning Sufficient to provide blood oxygen drum, enter > 4 = detect whether you are giving away oxygen-borne pulmonary fibrosis and other hidden diseases C: stimuli syndrome or special test principle based on ratio; 7 = 4 / R oximetry Concentration Burt's Law (Beer Lambert's 201106920

The intensity of the transmitted light caused by the blood wave wave _ diastolic and contraction (four); therefore, the blood flow in the tissue and the change of oxygen and non-oxygen hemoglobin will have different absorbance of the optical signal. The blood and concentration can be estimated by the difference in the composition of the light. Even if the portable oximeter 10 is attached to the wrist of the user, the pulse beat can be converted into a heartbeat value and a blood wave graphic output; = for the average user, the heartbeat value is only obtained. Refer to whether the number of heartbeats per minute is normal, and it is not possible to analyze the pulse-related human health information simply by the blood wave pattern to further determine whether there are other hidden diseases. In fact, the pulse vibration intensity, speed, etc. are important basis for Chinese medicine in the diagnosis of patients. The measured pulsation can obtain periodic vibration waves as shown in the fifth figure. Like the above portable oximeter 1 〇, the blood wave pattern that is rotated, the thick line in the figure is a periodic vibration wave, and the inside contains wavelets with different frequencies and different amplitudes (such as thin lines and dashed lines); if the appearance of the wave pattern is only seen from it It's just a continuous wave of fluctuations'. If not analyzed, how many different frequencies and their amplitudes are not known from the appearance. The relationship between pulse vibration wave and autonomic nerve activity is very close. Taking sympathetic nerve as an example, when the discharge frequency is low frequency band (0~10Hz), it is the basic function of maintaining blood, and the high frequency band (above 10Hz) The frequency is flat ^ activity is small, once the disease or the human body is stimulated, the nerve activity will increase, and 201106920 causes the high frequency frequency discharge above 10Hz to increase. Therefore, when it is sick, its =:: wave (4) conversion, the fluctuation of the door, and the amplitude of the waves of these different frequencies. The human heart beats about 72 times per minute. This is called the average hop interval and the average heartbeat cycle. The standard eccentricity of V 4 is different (the difference is about 40 milliseconds; Bracts, songs by Dan Zhi + brown The above-mentioned portable blood concentration meter 10' only has to output heartbeat values ', ~, method for detecting heart rate variability. Currently, heart rate variability is known to be related to heartbeat and heart The beating of the rhythmic discharge itself is also regulated by the autonomic nervous system (Aut〇n〇mk nerv〇us (10), ANS), which means that heart rate changes, autonomic nerves and heartbeats have Inseparable relationship. Heart rate variability represents the total activity of autonomic nerves; self-regulation and fine tuning & better and higher. The heart rate is affected by the autonomic nervous system of the human body, including the sympathetic nervous system and the parasitic nervous system. The former can increase the heart rate, the latter will lower the heart rate, and the heart rate will produce the best balance under the interaction of the two. In the past decade, many literatures have shown that the regulation of autonomic nerves There is a significant relationship between mortality associated with cardiovascular disease, such as sudden cardiac death, high blood pressure, and shock, and heart rate variability analysis has also been found to be an indicator of mortality after myocardial infarction. In the 2006 Engineering Technology and Chinese and Western Medicine Application Seminar, Sun Dejun and others proposed a new type of wrist physiological monitor _ heart rhythm master and its Chinese and Western medical applications to induce blood pressure waves by electric sensors, and the output combination ▲ dust, pulse and HRV analysis of non-invasive physiological monitors. However, the induction and processing of the wrist-type refractory device, when the analysis of heart rate variability is only shown on a physiological measurement value, although There are also police officers who can observe whether there are hidden symptoms. However, when a single value is used, the value will be temporarily misaligned due to external factors, such as whether the Qingxu is excited or not. External stimuli, etc., cannot be compared at the same time by other parties. Because of the above-mentioned rickets, computer users account for the majority; The inventor conceived that by providing a variety of health detection functions, the non-invasive detection device is integrated into a computer peripheral device that requires long-time contact, and a plurality of physiological information is outputted by precise circuit processing, so as to be operated by the user. When the computer is turned off, it is also possible to self-monitor the body state immediately, and then discover the body alarm early, so as not to delay the medical treatment opportunity. [Invention] The main object of the present invention is to provide a computer system for extracting physiological information, which can be operated by a user. During the computer, the user's physical state is further reflected, and the user is provided with the self-detecting physical state. To achieve the above object, the present invention provides a computer system for extracting physiological information, which can be used by the user during operation of the computer device. It further reflects the user's physical condition when holding the mouse. One of the computer systems, the mouse 201106920, is equipped with two illuminators to project different wavelengths of light to the user's finger artery. 'There is another light sensation in the mouse body. The detector can receive beams of different wavelengths reflected by the artery Obtaining one of the first and second signals; electrically connecting the optical sensor with an amplifying circuit, and filtering the first and second signals to remove DC bias, visible light noise, and power noise, respectively, and The amount of change in the first and second signals is taken out. Therefore, the computer device can receive the digital signals corresponding to the first and second signals and process them into three parts through a type of analog/digital converter (A/D Lu converter), and then classify into three parts; the first part is to calculate the blood oxygen concentration, and the need The light absorption caused by the relaxation and contraction of the tissue caused by the blood pressure wave when the first and second light beams penetrate the internal tissue of the human body to perform the blood oxygen saturation concentration calculation; the second part is the pulse spectrum analysis by the fast Fourier transform, The time domain of the arterial reflected wave is converted into the frequency domain, and the Spectral Energy Ratio (SER) method is used to analyze the autonomic nerve activity; the third part is to generate the heartbeat frequency and calculate the heart rate variability plus (10). Rate variability; HRV). After the three parts are classified and calculated, a number of physiological information can be displayed. When the user's body is in a problem and is unconscious, the computer system can provide an early warning based on the physiological information to indicate that the user seeks medical treatment or even further checks; the present invention has a use as compared with the prior art. Self-testing the characteristics of the body state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to explain the structure, features and functions of the present invention in detail, the following preferred embodiments are described with reference to the accompanying drawings, wherein: . Figure 1 is a block diagram of a circuit in accordance with a first preferred embodiment of the present invention. The third figure is a flow chart of the action of the first preferred embodiment of the present invention, which mainly reveals the operation of the computer device. Kiss, referring to the first to third figures, a computer system (10) for extracting physiological information according to a first preferred embodiment of the present invention includes a mouse body (2〇), a first illuminant (30), and a second Illuminant (4〇), _photo sensor (5〇), two amplifier circuit (6G), analog/digital, such as (four) gamma, a transmission interface (80), and a computer device (90), wherein : The mouse body (20) is installed around the computer farm (90) by the wheel interface (4) for the user to hold the operating device (4) the operating cursor (91). The second illuminator (3〇, 4〇) is disposed on the main body of the mouse (2〇), and generates a second-wavelength (thus, a tree) of different wavelengths to project a finger artery of the human body. The wavelength range of the first beam is 4 _ interesting to OOnm' j 帛 - the wavelength of the beam is preferably _ gamma, in this embodiment, the wavelength of the first beam is 660 nm, for example, Not as a limiting element. The wavelength of the second wire is from (10) to 〇〇〇nm, and the wavelength of the second beam is preferably 940 nm. In the present embodiment, the wavelength of the second beam is 94 〇 nm, and only For the sake of illustration, it is not intended as a limitation. The photo sensor (50) is disposed on the mouse body (20), and receives the first and second light beams reflected by the human finger artery - the second and second reflected light 201106920 (302, 402) Thus, a first and a second signal are generated, respectively. The amplifying circuit (60) is electrically connected to the photo sensor, and may be disposed inside the mouse body (20) or additionally mounted on the mouse body (20) as exemplified in the embodiment. The first signal and the second signal are processed by amplification filtering; the amplifying circuit (60) has a second-order high-pass filter (61), a gain amplifier (63), and a second-order low-pass filter (65) connected in series with each other. ), a differentiator (67) and an inverting amplifier (69). The input end of the high-pass filter (61) is electrically connected to the photo sensor (50), and the output end is electrically connected to the gain amplifier (63); the input end of the low-pass filter (65) is electrically connected to the gain An amplifier (63), the output end is electrically connected to the differentiator (67); the input end of the inverting amplifier (69) is electrically connected to the differentiator (67) 'The output end is electrically connected to the analog/digital converter (70) . Referring to the second figure, the first and second signals first pass through the second-order south pass filter (61), in order to remove the drift voltage formed by the finger shake and the DC bias of the light consumable to ensure the next level. The circuit does not enter the saturation region and cannot operate normally. After passing through the high-pass filter (61), the signal is input to the gain amplifier (63) to amplify the signal to facilitate the detection of the next-stage circuit; then the signal enters the second-order low-pass connected to each other. The filter (65) is designed to remove the visible light noise generated by the fluorescent lamp and the high frequency noise from the power supply respectively; then the signal enters the differentiator (67) to highlight the change of the previous signal to observe the change inside the signal. Because the pre-stage second-order high-pass filter (61) can remove the DC offset voltage, the DC effect can be effectively avoided, and the op amp of the differentiator (67) enters the saturation region so that the differentiator (67) does not hang the crane; The signal is input to the inverting amplifier (69) because the 201106920 differentiator (67) causes the signal iso. The change is made, so the signal must be restored to its original phase via the inverting amplifier (69). The input terminal of the analog/digital converter (70) is electrically connected to the inverting amplifier (69), and the output terminal is electrically connected to the transmission interface (80), and the analog/digital converter (70) is used to convert the analog signal into The digital signal corresponding to the signal transmission specification of the transmission interface (8〇) can be similarly disposed inside the mouse body (2〇) or additionally installed in the mouse body as exemplified in the embodiment (2〇) In the embodiment, the transmission interface (80) is a USB interface, which is merely an example of the definition, and is not intended to be a limitation. Therefore, after the first and second signals pass through the above amplifying circuit (60), the analog/digital converter (7〇) converts the first and second digital signals into a digital form for transmission to the transmission interface. (80). Referring to the third figure, after the first and second digital signals are transmitted to the computer device (90), the software processing installed in the computer device (90) is classified into three parts; the first part is the blood oxygen concentration, which needs to be calculated. The first and second light beams (301, 401) penetrate the internal tissue of the human body, the light absorbance caused by the relaxation and contraction of the tissue caused by the blood pressure wave, to calculate the blood oxygen saturation concentration; the second part is the fast Fourier transform, The pulsating time domain is converted into the frequency domain and the result after the nose is 'required by the Spectrai Energy Ratio (SER) method. The second part is to generate the heartbeat frequency and calculate the heart rate variability (heart). Rate variability ; HRV). The three parts of the classification, after the nose of the nose, and then the software interface shows a variety of physiological information (92, 94 '96 '98); the types of physiological information (92,94,96,98) are heartbeat Frequency, blood oxygen saturation concentration, autonomic nerve activity, and heart rate variability 201106920 analysis; in this embodiment, 'the physiological information _ type, which is merely an example here' is not a limiting element. The physiological resource tacting principle is as follows: 1. The physiological information (9 2 ) is a heartbeat frequency, which is known by monitoring the performance of the first signal and the second signal in the time domain. 2. The physiological information (94) is a blood oxygen saturation concentration, because the proportion of oxygenated hemoglobin and non-oxygen hemoglobin in the blood causes the human tissue layer to have different absorption for light, thereby affecting the first beam and The characteristic of the intensity of the reflection of the second beam. Since the first light beam and the second light beam use different wavelengths, the first signal and the second signal can be respectively displayed in a proportional characteristic of ten pairs of oxygenated heme and no hemoglobin; The first and second signals corresponding to the first and second signals respectively calculate the absorption of the first light beam and the second light beam by the human tissue layer for the purpose of detecting the blood oxygen saturation concentration. 2. The physiological information (96) is a pulse frequency for autonomic nerve activity, which is to pass the first signal or the second signal via a fast foudef tfansfer (FFT) to pulse From the time domain to the frequency domain to the spectrum (p. and Spe (10), decomposed into the original discrete spectrum; and then through the spectral energy ratio (ah resistance ratio, SER (/)) operation, the formula is Na (7) = do (7) & (7), , Medium / is the specific frequency 'A (7) is / Hz The spectrum of the integrated spectrum can be the energy of the integrated spectrum above / Hz. Therefore, the low frequency (〇 ~ι 〇Hz) energy and high frequency (above 10Hz) energy ratio Qing 〇) = ι〇〇 can be used as an indicator of the normal person and patient in the district 201106920, the normal person's card (ι〇) value is greater than 1 (8), and the patient's card ζψ )) is less than 100. At the same time, the energy of the normal human pulse wave spectrum is more than 99 1% from the normal person's card to be concentrated before 10 Hz. When the disease is sick, the spectrum energy above ι〇Ηζ is increased by the syndrome (1()) and the spectrogram. Causes changes in the spectrum above 10Ηζ. 4. The physiological information (98) is a heart rate variability analyzer, which monitors the interval between each heartbeat and compares it with the normal heartbeat value to know that 'the first record or the second The difference between the time interval of the signal and its time domain period. - The above-mentioned structure, the computer system (10) for extracting physiological information is provided by the present invention, which can reflect the physical state of the user in a step-by-step manner during non-invasive self-health detection during the operation of the mouse. / The human body's heart rate, blood oxygen saturation concentration, autonomic nerve activity and heart rate variability analysis four values 'provide users to pay m _ self-reading health condition 1 is normal, compared with other products can provide a variety of information. In the past, the invention scientifically diagnosed the pulse diagnosis of Chinese medicine, and cut the pulse from the vibration wave _ Fourier transform (four) to the object domain, and analyze the spectrum to tell the user whether the body is slightly sloppy or not. An important basis for medical treatment. When the body issues a problem and the ride is unconscious, the computer system (10) can connect to other peripheral devices or install the listening body through the computer device (90) according to the physiological information. Correction: to indicate the user's possible (4) problem; so as to enable the user to promptly seek medical treatment or to perform a further step-by-step inspection to further understand the physical condition or 201106920, the present invention is The constituent elements disclosed in the embodiments are merely illustrative and are not intended to limit the scope of the present invention. The alternative or variations of other equivalent elements are also covered by the scope of the patent application.
