Background technique

Cardiovascular disease has become one of the leading causes of death all over the world. Therefore, various detection methods of human cardiovascular circulation and their research and development are more generally valued. Among the current detection methods, the method of detecting the peripheral blood circulation of the human body by using the photoplethysmography (PPG) to describe the signal of photoplethysmography has gradually been paid attention to.

Fig. 1 is a pulse waveform diagram of a volume pulse of a digitized physiological signal of a physiological detection device according to the known technology. Please refer to Figure 1. The known calculation method of the physiological state index is based on the height difference a between the trough point d3 and the peak point d1 (that is, the systolic peak point) of the pulse, and the distance between the trough point d3 and the diastolic peak point d2.

Other embodiments are listed below for illustration. It must be noted here that the following embodiments use the component numbers and part of the content of the previous embodiments, wherein the same numbers are used to denote the same or similar components, and descriptions of the same technical content are omitted. For the description of omitted parts, reference may be made to the foregoing embodiments, and the following embodiments will not be repeated.

FIG. 2 is a schematic block diagram of a physiological detection device according to an embodiment of the invention. FIG. 3A is a schematic diagram of the physiological detection device of FIG. 2 . 3B and 3C are side views of the physiological detection device in FIG. 3A at different viewing angles. Please refer to FIG. 2 and FIG. 3A to FIG. 3C . In this embodiment, the physiological detection device 100 includes a main body 110 , a sensing unit 120 , a signal processing unit 130 and a computing module 140 . The sensing unit 120 is configured in the main body 110, and the sensing unit 120 can be used to detect the detected part 50 of the human body. In this embodiment, the sensing unit 120 is, for example, an optical volume change descriptor, and the sensing unit 120 detects and evaluates the amount of spectral energy absorbed by the light of a specific wavelength emitted and received by the sensing unit 120 The physiological state of the measured part 50 of the human body.

For example, the measured site 50 is a peripheral site such as a finger, a toe, and an earlobe of a human body. Please refer to FIG. 2, in this embodiment, the sensing unit 120 includes one or more groups (only one group is shown in FIG. 2 for illustration) of an optical transmitter 122 and an optical receiver 124, and the optical transmitter 122 And the form of the light receiver 124 can be a light-transmitting type or a light-reflecting type. In this embodiment, the light emitted by the light-transmitting light emitter 122 can reach the light receiver 124 after passing through the measured part 50 of the human body. In addition, when the light emitter 122 is a reflective light, after the light is emitted from the light emitter 122 and reaches the measured part 50 , the light can be reflected to the light receiver 124 through the measured part 50 .

In this embodiment, the light transmitter 122 and the light receiver 124 are, for example, infrared light transmitters and infrared light receivers that can emit and receive infrared light, and the wavelength range of the light emitted and received falls within 760 nanometers (nm ) and 1 millimeter (mm). However, this embodiment does not limit the wavelength range of the light emitted and received by the sensing unit 120. In other embodiments, the light emitted by the light transmitter 122 and the light receiver 124 can also be green light, and the wavelength of the light The range is between 495nm and 570nm. Alternatively, the light of the light emitter 122 and the light receiver 124 can also be red light, and the wavelength range thereof falls between 620 nanometers and 750 nanometers.

As shown in FIG. 2 , the sensing unit 120 can obtain the sensing signal S1 from the measured part 50 of the human body, which is, for example, the optical volume description signal sent by the aforementioned optical volume change descriptor. For example, since the concentration of hemoglobin in the blood of the human body can be regarded as approximately constant, the amount of hemoglobin in the blood vessel is positively correlated with the volume of blood. The amount of spectral energy absorbed by the hemoglobin in the blood vessel is used to infer the change of the blood volume in the blood vessel, and then the above-mentioned sensing signal S1 is obtained.

Based on the above, since the volume of blood in the blood vessels of the human body will increase and decrease periodically with the contraction and relaxation of the heart and blood vessels, the spectral energy absorbed by the blood in the light also follows the beating of the heart. After the light is received by the light receiver 124 of the sensing unit 120 , a sensing signal S1 that resembles periodic changes can be further generated.

Specifically, when the human heart contracts, blood is pumped from the ventricles into the arteries. At this time, as the volume of blood in the blood vessel increases, the spectral energy absorbed by the blood in the light also increases, and the magnitude of the sensing signal S1 of the sensing unit 120 also changes accordingly. Therefore, the change of the sensing signal S1 of the sensing unit 120 is related to the magnitude of the blood volume (perfusion rate) in the blood vessel of the measured part of the human body.

Please refer to FIG. 2 and FIG. 3A to FIG. 3C again.

In this embodiment, the filter 132 can band-pass filter the sensing signal S1 received by the signal processing unit 120 , and the range of the filtering frequency is, for example, between 0.5 Hz and 5 Hz. In this embodiment, the range of the filtering frequency of the filter 132 can be appropriately changed according to the actual measurement requirements of the physiological detection device 100 .

The amplifier of the signal processing unit 130 can automatically gain the sensing signal S1 to an appropriate magnitude. In addition, the analog-to-digital converter 136 can convert the sensing signal S1 which is an analog signal into a digital physiological signal S2 to facilitate subsequent signal processing and related calculations.

In this embodiment, the sensing signal S1 may first be subjected to signal gain through the amplifier 134 , and then the sensing signal S1 may be converted into a digital physiological signal S2 through the analog-to-digital converter 136 . The sequence of the signal processing of the above sensing signal S1 can be properly adjusted according to actual needs. For example, the sensing signal S1 can also be converted into a digital physiological signal S2 through the analog-to-digital converter 136 first, and then passed through the amplifier 134. Amplify the signal gain.

The computing module 140 is configured in the main body 110 and coupled to the signal processing unit 130 to receive the digitized physiological signal S2 processed by the signal processing unit 130 . In this embodiment, the calculation module 140 can be used to perform calculations on the digital physiological signal S2 to obtain information about feature points of the digital physiological signal S2.

In this embodiment, corresponding to the pulsation of the heart, blood is periodically injected into blood vessels from the ventricle of the heart, and the digital physiological signal S2 has multiple pulses generated in time sequence.

In this embodiment, the pulse of the digitized physiological signal S2 has a starting point P1 , a peak point P2 and a valley point P3 located at the leading edge of its rising edge, which can be respectively used as characteristic points of the digitized physiological signal S2 .

In this embodiment, the starting point P1 of the digitized physiological signal S2 reflects changes in pressure and volume in blood vessels when the human heart ends diastole and is ready to contract. The peak point P2 of the pulse is the highest point of the pulse, and the peak point P2 reflects the maximum pulse amplitude caused by the blood ejected from the ventricle and into the blood vessel when the heart contracts. In this embodiment, the rising band from the starting point P1 to the peak point P2 represents the process in which the blood volume in the arterial vessel suddenly and rapidly increases when the ventricle of the heart ejects blood rapidly, causing the vessel wall to expand rapidly. In addition, the descending slope section after the peak point P2 reflects the process in which the blood volume in the arterial vessel gradually decreases, and the vessel wall gradually returns to the state before expansion.

Please refer to FIG. 2 again. In this embodiment, the calculation module 140 includes a normalization processing unit 142 and a physiological state index calculation unit 144 . After the calculation module 140 completes the calculation of the feature points of the digital physiological signal S2, the calculation module 140 can use the regular processing unit 142 to normalize the digital physiological signal S2, so that the digital physiological signal S2 returns to the original signal size before the signal gain . Next, the physiological state index calculating unit 144 may calculate the physiological state index according to the first information and the second information of the feature points of the digitized physiological signal S2.

In detail, please refer to FIG. 4A and FIG. 4B. The horizontal horizontal axis of the pulse waveform of the digitized physiological signal S2 in FIG. 4A and FIG. Pulse size for volumetric pulses for digitized physiological signals. In this embodiment, the first information of the digitized physiological signal S2 is the integrated area A1 of the pulse between the starting point P1 and the peak point P2 in FIG. 4A with respect to the time axis, and the second information is the two-phase The integral area A2 of the pulse relative to the time axis between adjacent starting points P1 and P1'. The physiological state index calculation unit 144 of the calculation module 140 can calculate the ratio of the second information to the first information, that is, the ratio of the integral area A2 to A1, to obtain the corresponding physiological state index.

Please refer to FIG. 4C. In another embodiment, the first information may also be the time difference T1 between the starting point P1 and the peak point P2 in FIG. 4C, and the second information may be two adjacent The time difference T2 between the starting points P1, P1'. The calculation module 140 can also calculate the ratio of the aforementioned second information to the first information, that is, the ratio of the time difference T2 to the time difference T1 to obtain the corresponding physiological state index.

In this embodiment, the user of the physiological detection device 100 can evaluate the state of blood perfusion in blood vessels at the measured site and the state of blood circulation in the whole body according to the physiological state index calculated by the computing module 140 .

That is, the physiological detection device 100 of this embodiment extracts the second information directly from a complete cycle of pulses. Therefore, in addition to intercepting the second information from the pulses between two adjacent starting points P1 and P1', the physiological detection device of this embodiment can also use any recurring feature points on adjacent pulses (such as It is the pulse between the trough points P3) in FIG. 4A to intercept the second information. Therefore, the method of extracting and calculating the second information by the physiological detection device 100 of this embodiment is simpler than the known technology, and does not need to be limited to the diastolic wave and its Vertex position.

In addition, compared with the content of the known technology in FIG. 1 , the physiological detection device 100 of this embodiment is obtained by dividing the time difference between the starting point P1 and the peak point P2 and between the two starting points P1 and P1'.
