[0041] In the related art, in some medical scenarios, although the cuff-type blood pressure monitor based on the auscultation method or the oscillometric method can measure blood pressure more accurately, the operation of the device is relatively complicated and not easy to carry.

[0042] In order to solve the above technical problems, according to an embodiment of the present disclosure, a detection component is provided, which includes: a substrate, the substrate including a detection part facing an object to be detected; a fingerprint recognition module, which is arranged on a first side of the substrate, and detects a first detection parameter of the object to be detected, and the first side is a side of the substrate away from the detection part; a pressure detection module, which is arranged on the first side of the substrate, and the pressure detection module is arranged on a side of the fingerprint recognition module away from the substrate, and the pressure detection module detects the pressure parameter of the detection part; an electrocardiogram detection module, at least a part of the electrocardiogram detection module is exposed to the detection part, and the electrocardiogram detection module detects the electrocardiogram parameter of the object to be detected, wherein a first physiological parameter of the object to be detected is obtained through the first detection parameter and the pressure parameter; and a second physiological parameter of the object to be detected is obtained through the first detection parameter, the electrocardiogram parameter and a preset parameter.

[0044] It can be understood that the detection component involved in the present disclosure can be applicable to any terminal listed below.

[0045] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users.

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0046] Figure 1 It is a schematic structural diagram of a detection component according to an exemplary embodiment. Figure 2 is a schematic structural diagram of a detection component according to another exemplary embodiment.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the detection component 100 includes: a substrate 1, a fingerprint recognition module, a pressure detection module, and an electrocardiogram detection module.

[0048] The substrate 1 may be a surface that the object to be tested contacts when the detection assembly 100 performs detection. The substrate 1 may include a detection portion 10 facing the object to be tested and directly contacting the skin of the object to be tested. The substrate may include a first side, which may be a side of the substrate facing away from the detection portion.

[0049] The fingerprint recognition module may be disposed on the first side of the substrate 1 , and the fingerprint recognition module may be used to obtain fingerprint information of the object to be detected, and the fingerprint recognition module may also be used to detect a first detection parameter of the object to be detected.

[0050] The pressure detection module can be arranged on the first side of the substrate 1, and the pressure detection module is arranged on the side of the fingerprint recognition module away from the substrate 1. The pressure detection module can detect the pressure parameters exerted on the detection part 10. Exemplarily, the pressure detection module can obtain the pressure parameters exerted on the detection part 10 by detecting the deformation of the detection part 10 or the pressure detection module itself.

[0051] At least a portion of the ECG detection module may be exposed to the detection portion, and the ECG detection module may detect ECG parameters of the subject to be detected.

[0052] A first physiological parameter of the object to be measured can be obtained through the first detection parameter and the pressure parameter, and a second physiological parameter of the object to be measured can be obtained through the first detection parameter, the electrocardiogram parameter and the preset parameter.

[0053] The first physiological parameter and the second physiological parameter may be any other physiological parameters used for health monitoring of the object to be measured.

[0054] The first physiological parameter and the second physiological parameter may also be the same physiological parameter measured using different methods and parameters.

[0055] For example, the first physiological parameter may be the blood pressure of the subject to be measured, the second physiological parameter may also be the blood pressure of the subject to be measured, and the electrocardiogram parameter may be the electrocardiogram data of the subject to be measured.

[0056] For example, due to the periodic pumping of blood by the heart, the pressure pulse wave is transmitted in the arterial vascular system, and the pressure pulsation causes the hemoglobin volume rate in the blood vessels to change. The fingerprint recognition module can extract the photoplethysmography (PPG) signal of the object to be tested through the transmitted or reflected light. Based on the photoplethysmography signal, the blood pressure of the object to be tested can be calculated through the pulse wave transmission time square algorithm.

[0057] The heart rate parameters of the subject to be tested can be obtained through the ECG detection module. The pulse wave fluctuation parameters of the distal limbs of the subject to be tested can be compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is significantly correlated with the change of blood pressure and is inversely proportional to the change of blood pressure, the blood pressure of the subject to be tested can be calculated based on the pulse wave conduction time method. The calculation formula is as follows:

[0058] Blood pressure = A / pulse transit time + B

[0059] Among them, A and B are constants, for example, A and B can be preset parameters.

[0060] The present invention realizes the sharing of the fingerprint recognition module by coordinating the fingerprint recognition module with the pressure detection module and the electrocardiogram detection module respectively, realizes the composite design of fingerprint recognition and health monitoring functions, and realizes multiple detection methods for physiological parameters to facilitate the subsequent detection method calibration or data calibration function, thereby improving the operability and ease of use of the device.

[0061] In some embodiments, the fingerprint recognition module may be a photoelectric fingerprint recognition module or an ultrasonic fingerprint recognition module.

[0062] The first detection parameter may include a pulse fluctuation parameter of the subject to be detected and a pressing area parameter of the subject to be detected. Exemplarily, the pulse fluctuation parameter may be a fluctuation value of the skin surface of the subject to be detected caused by the pulse.

[0063] When the subject is undergoing blood pressure monitoring, the subject can press the detection component 100 according to the recommended pressure, thereby obtaining a pressure change curve that first increases and then decreases.

[0064] Exemplarily, when the fingerprint recognition module is an ultrasonic fingerprint recognition module, the ultrasonic fingerprint recognition module can use an ultrasonic transducer to transmit an ultrasonic pulse signal, and then receive the reflected ultrasonic pulse, and calculate the position of the reflection interface according to the time delay of the received pulse signal to realize the ranging function. The skin surface of the object to be measured can be displaced due to the pulse of the object to be measured, and the data parameters of the pulse fluctuation can be obtained by detecting the displacement data of the skin surface of the object to be measured. Therefore, the fingerprint recognition module is attached to the skin surface of the object to be measured, and ultrasonic pulses are continuously emitted to the object to be measured, and the reflected echo signal is received, so that the displacement data of the skin surface of the object to be measured due to the pulse can be obtained, and the pulse fluctuation parameters can be obtained by the displacement data.

[0065] Exemplarily, when the fingerprint recognition module is a photoelectric fingerprint recognition module, the photoelectric fingerprint recognition module is based on the measurement principle of the photoelectric effect. The skin tissue is illuminated by an infrared light source, and the light reflected by the illuminated tissue is received by the photoelectric sensor of the photoelectric fingerprint recognition module and converted into an electrical signal. When the heart beats, the blood flow causes the volume of the skin blood vessels to change, thereby causing the reflected light intensity of the illuminated tissue to change. By detecting the data of the reflected light intensity, the data parameters of the pulse fluctuation can be obtained. The photoelectric fingerprint recognition module can convert the received light signal into an electrical signal, and obtain the pulse fluctuation parameters after amplifying and filtering the electrical signal.

[0066] The pressure detection module can record the pressure parameters in real time. The detection component 100 can calculate the pressing pressure parameters according to the pressing area parameters and the pressure parameters, and then combine the fluctuation value, the pressing pressure parameters and the relative coefficient to obtain the blood pressure parameters of the object to be tested.

[0067] Exemplarily, Um may be the fluctuation peak value obtained by the fingerprint recognition module, Pm may be the pressure parameter corresponding to Um, and Pm may be recorded as the average blood pressure.

[0068] The systolic pressure Ps may be equal to the pressure parameter corresponding to the first fluctuation value Us obtained by multiplying the fluctuation peak value Um by the first relative coefficient Ks. The first relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the first relative coefficient Ks may be 0.5.

[0069] The diastolic pressure Pd may be equal to the pressure parameter corresponding to the second fluctuation value Ud obtained by multiplying the fluctuation peak value Um by the second relative coefficient Kd. The second relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the second relative coefficient Ks may be 0.8.

[0070] In some embodiments, the detection component 100 may include: a circuit board 33, which may be arranged on a side of the fingerprint recognition module and the electrocardiogram detection module away from the substrate 1, and the circuit board 33 may be electrically connected to the fingerprint recognition module, the pressure detection module and the electrocardiogram detection module.

[0071] The processing module can be connected to the fingerprint recognition module, the pressure detection module and the electrocardiogram detection module through the circuit board 33, and then receive the first detection parameter from the fingerprint recognition module, the pressure parameter from the pressure detection module and the electrocardiogram parameter from the electrocardiogram detection module.

[0072] The processing module can obtain an intermediate constant through the first detection parameter, the ECG parameter and the first physiological parameter, and configure the intermediate constant as a preset parameter, thereby realizing calibration of the method of obtaining physiological parameters through the first detection parameter, the ECG parameter and the preset parameter.

[0073] For example, the pulse fluctuation parameters of the distal limbs of the subject to be tested can be obtained through the fingerprint recognition module, and the heart rate parameters of the subject to be tested can be obtained through the electrocardiogram detection module. The pulse fluctuation parameters of the distal limbs of the subject to be tested are compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is inversely proportional to the change in blood pressure, the blood pressure of the subject to be tested can be calculated based on the pulse conduction time method. The calculation formula is as follows:

[0074] Blood pressure = A / pulse transit time + B

[0075] Among them, A and B are constants, and since the values ​​of A and B are related to the user's physique, the blood pressure of the object to be measured can be obtained by combining the pulse fluctuation parameters and the pressure parameters, and then combined with the known blood pressure results and the known corresponding first detection parameters and electrocardiogram parameters, the intermediate constants can be fitted, that is, the values ​​of A and B in the subsequent measurement process.

[0076] Since the method of obtaining blood pressure through pulse fluctuation parameters and pressure parameters requires continuous pressing of the detection unit 10, while the method of obtaining blood pressure through pulse fluctuation parameters and electrocardiogram parameters does not require continuous pressing, the latter operation is simpler and easier for users to operate.

[0077] In some embodiments, Figure 1 and Figure 2 As shown, the fingerprint recognition module may include: a signal element 21 and a sensing element 22. The signal element 21 may be an optical signal element or an ultrasonic signal element 21.

[0078] The signal element 21 may be disposed on the first side of the substrate 1, and the signal element 21 may transmit a first signal to the object to be measured, and the object to be measured may reflect the first signal to generate a first sub-signal;

[0079] The sensing element 22 may be disposed on the first side of the substrate 1 , and the sensing element 22 may receive the first sub-signal.

[0080] The sensing element 22 may include a side surface intersecting with the plane where the substrate 1 is located, and the signal element 21 is disposed around the side surface of the sensing element 22 .

[0081] When the fingerprint recognition module is an ultrasonic fingerprint recognition module, the signal element 21 can emit an ultrasonic pulse signal, and the induction element 22 receives the reflected ultrasonic pulse, and calculates the position of the reflection interface according to the time delay of the received pulse signal to achieve the distance measurement function. The detection unit 10 is attached to the skin surface of the object to be measured, and ultrasonic pulses are continuously emitted to the object to be measured, and the reflected echo signal is received, so that the pulse fluctuation parameters generated by the pulse on the skin surface of the object to be measured can be obtained.

[0082] When the fingerprint recognition module is a photoelectric fingerprint recognition module, the signal element 21 can illuminate the skin tissue through an infrared light source based on the measurement principle of the photoelectric effect, and the light reflected by the illuminated tissue is received by the sensor element 22 and converted into an electrical signal. When the heart beats, the blood flow causes the volume of the skin blood vessels to change, thereby causing the reflected light intensity of the illuminated tissue to change. The sensor element 22 converts the received light signal into an electrical signal, and after amplification and filtering, obtains the pulse fluctuation parameter.

[0083] The sensing element 22 can generate a first detection parameter through the first sub-signal, and the sensing element 22 can output the first detection parameter to the processing module, so that the processing module can perform calculations based on the first detection parameter. The first detection parameter can include a pulse fluctuation parameter of the subject to be measured and a pressing area parameter of the subject to be measured. For example, the pulse fluctuation parameter can be a fluctuation value of the skin surface of the subject to be measured caused by the pulse.

[0084] In some embodiments, when the fingerprint detection module is a photoelectric fingerprint detection module, the detection unit 10 may be a transparent member so that the optical signal can pass through the detection unit 10 and the detection component 100 can work normally.

[0085] In some embodiments, the fingerprint recognition module can detect other physiological parameters such as blood oxygen and heart rate.

[0086] In some embodiments, Figure 1 and Figure 2 As shown, the pressure detection module may include: a pressure sensing element, which is disposed on the first side of the substrate 1 and is electrically connected to the processing module.

[0087] The pressure sensing element can detect the pressure parameter of the detection part 10 . For example, the pressure sensing element can obtain the pressure parameter of the detection part 10 by detecting the deformation of the detection part 10 or the pressure sensing element itself.

[0088] In some embodiments, Figure 1 As shown, the pressure sensing element may include: an elastic member 32 and a pressure sensing circuit 31 .

[0089] The elastic member 32 can be arranged on the first side of the substrate 1. When the object to be tested presses the detection part 10, the elastic member 32 can be deformed. The pressure sensing circuit 31 detects the deformation of the elastic member 32 and outputs the deformation of the elastic member 32 as a pressure parameter to the processing module, thereby completing the detection of the pressure parameter.

[0090] In some embodiments, Figure 1 As shown, at least a portion of the circuit board 33 can be fixed to the surface of the elastic member 32. When the elastic member 32 is deformed, the elastic member 32 can drive the circuit board 33 to be deformed.

[0091] The pressure sensing circuit 31 is disposed on the circuit board 33 , so that when the elastic member 32 is deformed, the circuit board 33 is deformed as well. The pressure sensing circuit 31 outputs pressure parameters to the processing module through the deformation of the elastic member 32 , thereby completing the detection of the pressure parameters.

[0092] For example, in some embodiments, the circuit board 33 may be a flexible circuit board.

[0093] In some embodiments, Figure 2 As shown, the pressure sensing element may include: a pressure chip 34. The pressure chip 34 is a chip that combines a micro-mechanical structure with an electronic component, and the pressure chip 34 may be electrically connected to the circuit board 33. It uses micro-nano manufacturing technology to manufacture tiny mechanical components on the chip surface and interconnect with circuit components, thereby achieving pressure measurement through the cooperation between the satellite mechanical structure and the circuit components.

[0094] The pressure chip 34 is disposed on the first side of the substrate 1 in the thickness direction of the detection component 100 . The pressure chip 34 outputs pressure parameters to the processing module, thereby completing the detection of the pressure parameters.

[0095] For example, the pressure chip 34 may be a MEMS (Micro-Electro-Mechanical Systems) pressure chip.

[0096] In some embodiments, Figure 1 and Figure 2 As shown, the ECG detection module may include: a conductive member 41, at least a portion of which may be disposed on the second side of the substrate 1, and the conductive member 41 may be electrically connected to the circuit board 33, wherein the second side of the substrate 1 and the first side of the substrate 1 are opposite sides of the substrate 1, so that the conductive member 41 may be in direct contact with the skin surface of the object to be detected.

[0097] The conductive member 41 may be a conductive component, and by directly contacting the skin of the subject to be tested, the conductive member 41 may detect the ECG parameters of the subject to be tested. The conductive member 41 may be electrically connected to the processing module, and the conductive member 41 may output the ECG parameters to the processing module, so that the processing module may perform calculations based on the ECG parameters.

[0098] In some embodiments, Figure 1 and Figure 2 As shown, the conductive member 41 is disposed around the detection part 10. By disposing the conductive member 41 around the detection part 10, the contact area between the user and the detection part 10 can be fixed to the area surrounded by the conductive member 41, thereby eliminating the detection step of detecting the contact area between the object to be detected and the contact part, reducing the detection steps of the detection component 100, and simplifying the detection process of the detection component 100.

[0099] Figure 3 is a schematic structural diagram of a pressure sensing circuit according to an exemplary embodiment.

[0100] In some embodiments, Figure 3 As shown, the pressure sensing circuit 31 may include: a power supply terminal Vcc, a first pressure sensitive group 51 and a second pressure sensitive group 61. The power supply terminal Vcc is used to supply power to the first pressure sensitive group 51 and the second pressure sensitive group 61.

[0101] The first pressure-sensitive group 51 can be electrically connected to the power supply terminal Vcc, and the first pressure-sensitive group 51 can output a first voltage. When the first pressure-sensitive group 51 is subjected to pressure, the resistance of the first pressure-sensitive group 51 changes, and the first voltage output by the first pressure-sensitive group 51 also changes accordingly.

[0102] The second pressure-sensitive group 61 can be electrically connected to the power supply terminal Vcc, and the second pressure-sensitive group 61 can output a second voltage. When the second pressure-sensitive group 61 is subjected to pressure, the resistance of the second pressure-sensitive group 61 changes, and the second voltage output by the second pressure-sensitive group 61 also changes accordingly.

[0103] Among them, the processing module can obtain the pressure parameter of the detection part 10 according to the difference between the first voltage and the second voltage. Exemplarily, as the pressure on the detection part 10 increases, the difference between the first voltage and the second voltage can increase. By calculating the difference between the first voltage and the second voltage, the influence of the initial resistance value of the first pressure-sensitive group 51 and the initial resistance value of the second pressure-sensitive group 61 due to time or external force factors can be reduced during the difference calculation process, thereby improving the accuracy of the pressure detection module in obtaining the pressure parameters, and thereby improving the detection accuracy of the detection component 100.

[0104] In some embodiments, Figure 3 As shown, the first voltage-sensitive group 51 may include a first output terminal V1 , and the first output terminal V1 may output a first voltage.

[0105] The second voltage-sensitive group 61 may include a second output terminal V2 , and the second output terminal V2 may output a second voltage.

[0106] When the pressure on the first pressure-sensitive group 51 increases, the first voltage decreases, and when the pressure on the second pressure-sensitive group 61 increases, the second voltage increases. By making the change trend of the first voltage opposite to the change trend of the pressure on the first pressure-sensitive group 51 and making the change trend of the first voltage the same as the change trend of the pressure on the first pressure-sensitive group 51, the difference between the first voltage and the second voltage can be increased as the pressure on the detection unit 10 increases, and then the pressure parameter on the detection unit 10 can be obtained according to the difference between the first voltage and the second voltage.

[0107] The present disclosure is not limited thereto, and the first pressure-sensitive group 51 and the second pressure-sensitive group 61 may also be configured such that when the pressure on the first pressure-sensitive group 51 increases, the first voltage increases, and when the pressure on the second pressure-sensitive group 61 increases, the second voltage decreases.

[0108] In some embodiments, Figure 3 As shown, the first pressure-sensitive group 51 may include a first resistor 52 and a first varistor 53. The first resistor 52 is a fixed-value resistor, and the resistance value of the first varistor 53 changes according to the pressure to which the first varistor 53 is subjected. For example, the resistance value of the first varistor 53 increases as the pressure to which the first varistor 53 is subjected increases.

[0109] One end of the first varistor 53 can be electrically connected to the power supply terminal Vcc, the other end of the first varistor 53 can be electrically connected to the first output terminal V1, one end of the first resistor 52 can be electrically connected to the first varistor 53, and the other end of the first resistor 52 can be grounded. This can make the first voltage output by the first output terminal V1 decrease when the pressure on the first varistor 53 increases.

[0110] In some embodiments, Figure 3 As shown, the second varistor group 61 may include a second resistor 62 and a second varistor 63. The second resistor 62 is a fixed resistor, and the resistance value of the second varistor 63 changes according to the pressure applied to the second varistor 63. For example, the resistance value of the second varistor 63 increases as the pressure applied to the second varistor 63 increases.

[0111] One end of the second resistor 62 can be electrically connected to the power supply terminal Vcc, the other end of the second resistor 62 can be electrically connected to the second output terminal V2, one end of the second varistor 63 can be electrically connected to the second varistor 63, and the other end of the second varistor 63 can be grounded. This can make the second voltage output by the second output terminal V2 increase when the pressure on the second varistor 63 increases.

[0112] By making the changing trend of the first voltage opposite to the changing trend of the pressure applied to the first pressure-sensitive group 51, and making the changing trend of the first voltage the same as the changing trend of the pressure applied to the first pressure-sensitive group 51, the difference between the first voltage and the second voltage can be increased as the pressure applied to the detection part 10 increases, and then the pressure parameters applied to the detection part 10 can be obtained based on the difference between the first voltage and the second voltage.

[0113] In some embodiments, the resistance value of the first resistor 52 , the resistance value of the second resistor 62 , the initial resistance value of the first varistor 53 , and the initial resistance value of the second varistor 63 are equal.

[0114] The initial resistance value of the first piezoresistors 53 is the resistance value of the first piezoresistors 53 when the first piezoresistors 51 are not subjected to the pressure of the object to be measured.

[0115] The initial resistance value of the second piezoresistors 63 is the resistance value of the second piezoresistors 63 when the second pressure-sensitive group 61 is not subjected to pressure from the object to be measured.

[0116] By making the resistance value of the first resistor 52, the resistance value of the second resistor 62, the initial resistance value of the first varistor 53 and the initial resistance value of the second varistor 63 equal, the first voltage and the second voltage can be equal when the detection component 100 is not performing detection, and the first voltage and the second voltage are both half of the voltage of the power supply terminal Vcc, thereby reducing the process of measuring and calibrating the initial values ​​of the first voltage and the second voltage. In the difference calculation, the difference can be made to start with 0 to facilitate subsequent calculations by the processor.

[0117] Based on the same concept, an embodiment of the present disclosure also provides an electronic device.

[0118] The electronic device may be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a message transceiver device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translation machine, and a wearable device such as a watch or a bracelet, and may be any electronic device having the detection component 100. In the following description, a mobile phone is taken as an example, but the present disclosure is not limited thereto.

[0119] Figure 4 The figure is a schematic diagram showing the structure of an electronic device according to an exemplary embodiment.

[0120] In some embodiments, Figure 4 As shown, the electronic device may include a detection component 100. By setting the detection component 100 on the electronic device, the functionality of the electronic device is expanded, and portable physiological detection based on the electronic device is realized, which helps to conveniently detect the physiological parameters of the object to be detected and improves the user experience.

[0121] In some embodiments, Figure 4 As shown, the electronic device may include a housing, and the housing may be provided with an opening, and the opening may expose the substrate 1, so that a user may directly contact the substrate 1 and complete the physiological parameter detection.

[0122] In some embodiments, at least a portion of the shell may be a substrate 1. Exemplarily, a shell portion of the shell may be a substrate 1. Using a portion of the shell as the substrate 1 may reduce production steps for the detection component 100 and the shell, thereby reducing production costs.

[0123] In some embodiments, the housing may be a rear case of an electronic device, and the detection component 100 may fit the rear case of the electronic device, thereby preventing the detection component 100 from occupying the setting space of the screen and ensuring the integrity of the screen.

[0124] Based on the same concept, the embodiment of the present disclosure also provides a detection method for detecting physiological parameters of a subject to be detected.

[0125] Figure 5 is a flow chart of a detection method according to an exemplary embodiment. Figure 5 As shown, the detection method may include:

[0126] S10: Acquire a first detection parameter and an electrocardiogram parameter of the subject to be detected at a first time and a pressure parameter of the detection unit, wherein the first detection parameter includes a pulse parameter of the subject to be detected;

[0127] S20: Outputting a physiological parameter at a first time according to the first detection parameter and the pressure parameter;

[0128] S30: Acquire preset parameters according to the first detection parameter, the electrocardiogram parameter and the physiological parameter at the first time;

[0129] S40: Acquire the first detection parameter and the electrocardiogram parameter of the object to be detected at the second time;

[0130] S50: Outputting the physiological parameters at the second time according to the first detection parameters at the second time, the electrocardiogram parameters and the preset parameters.

[0131] The first detection parameter may include a pulse parameter of the subject to be detected. For example, the first detection parameter may include a pulse fluctuation parameter and a compression area parameter. The physiological parameter may be a blood pressure parameter of the subject to be detected.

[0132] When the detection component 100 is in the first time, the pulse fluctuation parameters of the distal limbs of the object to be detected can be obtained through the fingerprint recognition module, the heart rate parameters of the object to be detected can be obtained through the electrocardiogram detection module, and the pressure parameters of the detection part 10 can be obtained through the pressure detection module.

[0133] According to the parameter results obtained in the first time, the detection component 100 can perform the first blood pressure detection method.

[0134] When the subject is undergoing blood pressure monitoring, the subject can press the detection component 100 according to the recommended pressure, thereby obtaining a pressure change curve that first increases and then decreases.

[0135] When the fingerprint recognition module is an ultrasonic fingerprint recognition module, the ultrasonic fingerprint recognition module can use an ultrasonic transducer to emit an ultrasonic pulse signal, then receive the reflected ultrasonic pulse, calculate the position of the reflection interface according to the time delay of the received pulse signal, and realize the ranging function. The fingerprint recognition module is attached to the skin surface of the object to be measured, and ultrasonic pulses are continuously emitted to the object to be measured, and the reflected echo signal is received, so that the pulse fluctuation parameters generated by the pulse on the skin surface of the object to be measured can be obtained.

[0136] When the fingerprint recognition module is a photoelectric fingerprint recognition module, the photoelectric fingerprint recognition module is based on the measurement principle of the photoelectric effect. The infrared light source is used to illuminate the skin tissue, and the light reflected by the illuminated tissue is received by the photoelectric sensor and converted into an electrical signal. When the heart beats, the blood flow causes the volume of the skin blood vessels to change, thereby causing the reflected light intensity of the illuminated tissue to change. The photoelectric fingerprint recognition module converts the received light signal into an electrical signal, and after amplification and filtering, the pulse fluctuation parameter is obtained.

[0137] The pressure detection module can record the pressure parameters in real time. The detection component 100 can calculate the pressing pressure parameters according to the pressing area parameters and the pressure parameters, and then combine the fluctuation value, the pressing pressure parameters and the relative coefficient to obtain the blood pressure parameters of the object to be tested at the first time.

[0138] For example, Um may be the pulse fluctuation peak value obtained by the fingerprint recognition module, Pm may be the pressure parameter corresponding to Um, and Pm may be recorded as the average blood pressure.

[0139] The systolic pressure Ps may be equal to the pressure parameter corresponding to the first fluctuation value Us obtained by multiplying the fluctuation peak value Um by the first relative coefficient Ks. The first relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the first relative coefficient Ks may be 0.5.

[0140] The diastolic pressure Pd may be equal to the pressure parameter corresponding to the second fluctuation value Ud obtained by multiplying the fluctuation peak value Um by the second relative coefficient Kd. The second relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the second relative coefficient Ks may be 0.8.

[0141] The blood pressure parameter result at the first time obtained by the first blood pressure detection method is used as a reference result to calibrate the second blood pressure detection method.

[0142] The pulse wave parameters at the distal end of the subject's limbs are compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is inversely proportional to the change in blood pressure, the blood pressure of the subject can be calculated based on the pulse wave conduction time method. The calculation formula is as follows:

[0143] Blood pressure = A / pulse transit time + B

[0144] Among them, A and B are constants.

[0145] Among them, A and B are constants, and because the values ​​of A and B are related to the physical constitution of the object to be tested, the benchmark results can be substituted into the above calculation formula, and then the intermediate constants can be obtained by data fitting, and the values ​​of the intermediate constants can be configured as the values ​​of A and B.

[0146] During the blood pressure parameter detection process at the second time, that is, during the blood pressure parameter detection process after calibration is completed, the intermediate constant can be configured as a preset parameter, and the object to be measured can use the second blood pressure detection method calibrated according to the physique of the object to be measured, thereby realizing self-calibration of the detection component 100 for the second blood pressure detection method.

[0147] Since the method of obtaining blood pressure through pulse fluctuation parameters and pressure parameters requires continuous pressing of the detection part 10, while the method of obtaining blood pressure through pulse fluctuation parameters and electrocardiogram parameters does not require continuous pressing, the operation of the second blood pressure detection method is simpler and easier for users to operate.

[0148] Figure 6 It is a flowchart of a detection method according to an exemplary embodiment.

[0149] In some embodiments, Figure 6 As shown, the detection method may include:

[0150] S10: Acquire a first detection parameter and an electrocardiogram parameter of the subject to be detected at a first time and a pressure parameter of the detection unit, wherein the first detection parameter includes a pulse parameter of the subject to be detected;

[0151] S21: The pulse parameter may include a pulse fluctuation parameter and a pulse fluctuation peak value;

[0152] S22: according to the corresponding relationship between the pulse fluctuation parameter and the pressure parameter at the same time during the detection process, confirming the corresponding curve between the pulse fluctuation parameter and the pressure parameter;

[0153] S23: determining a target pulse fluctuation parameter according to the product of the preset relationship value and the pulse fluctuation peak value;

[0154] S24: confirming a first pressure parameter corresponding to the target pulse fluctuation parameter according to a corresponding curve of the pulse fluctuation parameter and the pressure parameter at the same time, wherein the value of the first pressure parameter is the value of the physiological parameter at the first time;

[0155] S30: Acquire preset parameters according to the first detection parameters at the first time, the electrocardiogram parameters, and the physiological parameters at the first time;

[0156] S40: Acquire the first detection parameter and the electrocardiogram parameter of the object to be detected at the second time;

[0157] S50: Outputting the physiological parameters at the second time according to the first detection parameters at the second time, the electrocardiogram parameters and the preset parameters.

[0158] Exemplarily, the first detection parameter may further include a pressing area parameter. The physiological parameter may be a blood pressure parameter of the subject to be detected.

[0159] When the detection component 100 is in the first time, the pulse fluctuation parameters of the distal limbs of the object to be detected can be obtained through the fingerprint recognition module, the heart rate parameters of the object to be detected can be obtained through the electrocardiogram detection module, and the pressure parameters of the detection part 10 can be obtained through the pressure detection module.

[0160] According to the parameter results obtained in the first time, the detection component 100 can perform the first blood pressure detection method.

[0161] When the subject is undergoing blood pressure monitoring, the subject can press the detection component 100 according to the recommended pressure, thereby obtaining a pressure change curve that first increases and then decreases.

[0162] When the fingerprint recognition module is an ultrasonic fingerprint recognition module, the ultrasonic fingerprint recognition module can use an ultrasonic transducer to emit an ultrasonic pulse signal, then receive the reflected ultrasonic pulse, calculate the position of the reflection interface according to the time delay of the received pulse signal, and realize the ranging function. The fingerprint recognition module is attached to the skin surface of the object to be measured, and ultrasonic pulses are continuously emitted to the object to be measured, and the reflected echo signal is received, so that the pulse fluctuation parameters generated by the pulse on the skin surface of the object to be measured can be obtained.

[0163] When the fingerprint recognition module is a photoelectric fingerprint recognition module, the photoelectric fingerprint recognition module is based on the measurement principle of the photoelectric effect. The infrared light source is used to illuminate the skin tissue, and the light reflected by the illuminated tissue is received by the photoelectric sensor and converted into an electrical signal. When the heart beats, the blood flow causes the volume of the skin blood vessels to change, thereby causing the reflected light intensity of the illuminated tissue to change. The photoelectric fingerprint recognition module converts the received light signal into an electrical signal, and after amplification and filtering, the pulse fluctuation parameter is obtained.

[0164] The pressure detection module can record the pressure parameters in real time. The detection component 100 can calculate the pressing pressure parameters according to the pressing area parameters and the pressure parameters, and then combine the fluctuation value, the pressing pressure parameters and the relative coefficient to obtain the blood pressure parameters of the object to be tested at the first time.

[0165] For example, Um can be the pulse fluctuation peak value obtained by the fingerprint recognition module, Pm can be the pressure parameter corresponding to Um, and Pm can be recorded as the average blood pressure. The preset relationship value can include a first relative coefficient Ks and a second relative coefficient Kd. The first relative coefficient Ks and the second relative coefficient Kd can be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the first relative coefficient Ks can be 0.5, and the second relative coefficient Ks can be 0.8

[0166] According to the corresponding curves of the pulse fluctuation parameter and the pressure parameter at the same time, the first pressure parameter corresponding to the target pulse fluctuation parameter is confirmed, wherein the value of the first pressure parameter is the value of the physiological parameter at the first time. For example, the first pressure parameter may include systolic pressure Ps and diastolic pressure Pd.

[0167] The systolic pressure Ps may be equal to the pressure parameter corresponding to the first fluctuation value Us obtained by multiplying the fluctuation peak value Um by the first relative coefficient Ks.

[0168] The diastolic pressure Pd may be equal to the pressure parameter corresponding to the second fluctuation value Ud obtained by multiplying the fluctuation peak value Um by the second relative coefficient Kd.

[0169] The blood pressure parameter result at the first time obtained by the first blood pressure detection method is used as a reference result to calibrate the second blood pressure detection method.

[0170] The pulse wave parameters at the distal end of the subject's limbs are compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is inversely proportional to the change in blood pressure, the blood pressure of the subject can be calculated based on the pulse wave conduction time method. The calculation formula is as follows:

[0171] Blood pressure = A / pulse transit time + B

[0172] Among them, A and B are constants.

[0173] Among them, A and B are constants, and because the values ​​of A and B are related to the physical constitution of the object to be tested, the benchmark results can be substituted into the above calculation formula, and then the intermediate constants can be obtained by data fitting, and the values ​​of the intermediate constants can be configured as the values ​​of A and B.

[0174] During the blood pressure parameter detection process at the second time, that is, during the blood pressure parameter detection process after calibration is completed, the intermediate constant can be configured as a preset parameter, and the object to be measured can use the second blood pressure detection method calibrated according to the physique of the object to be measured, thereby realizing self-calibration of the detection component 100 for the second blood pressure detection method.

[0175] Since the method of obtaining blood pressure through pulse fluctuation parameters and pressure parameters requires continuous pressing of the detection part 10, while the method of obtaining blood pressure through pulse fluctuation parameters and electrocardiogram parameters does not require continuous pressing, the operation of the second blood pressure detection method is simpler and easier for users to operate.

[0176] Figure 7 It is a flowchart of a detection method according to an exemplary embodiment.

[0177] In some embodiments, Figure 7 As shown, the detection method may include:

[0178] S10: Acquire a first detection parameter and an electrocardiogram parameter of the subject to be detected at a first time and a pressure parameter of the detection unit, wherein the first detection parameter includes a pulse parameter of the subject to be detected;

[0179] S20: Outputting a physiological parameter at a first time according to the first detection parameter and the pressure parameter;

[0180] S31: Determine the pulse transmission time according to the first detection parameter and the electrocardiogram parameter;

[0181] S32: confirming the preset parameters according to the fitting relationship between the physiological parameters at the first time and the pulse transmission time;

[0182] S40: Acquire the first detection parameter and the electrocardiogram parameter of the object to be detected at the second time;

[0183] S50: Outputting the physiological parameters at the second time according to the first detection parameters at the second time, the electrocardiogram parameters and the preset parameters.

[0184] The first detection parameter may include a pulse parameter of the subject to be detected. For example, the first detection parameter may include a pulse fluctuation parameter and a compression area parameter. The physiological parameter may be a blood pressure parameter of the subject to be detected.

[0185] When the detection component 100 is in the first time, the pulse fluctuation parameters of the distal limbs of the object to be detected can be obtained through the fingerprint recognition module, the heart rate parameters of the object to be detected can be obtained through the electrocardiogram detection module, and the pressure parameters of the detection part 10 can be obtained through the pressure detection module.

[0186] According to the parameter results obtained in the first time, the detection component 100 can perform the first blood pressure detection method.

[0187] When the subject is undergoing blood pressure monitoring, the subject can press the detection component 100 according to the recommended pressure, thereby obtaining a pressure change curve that first increases and then decreases.

The photoelectric fingerprint recognition module converts the received light signal into an electrical signal, and after amplification and filtering, the pulse fluctuation parameter is obtained.

[0190] The pressure detection module can record the pressure parameters in real time. The detection component 100 can calculate the pressing pressure parameters according to the pressing area parameters and the pressure parameters, and then combine the fluctuation value, the pressing pressure parameters and the relative coefficient to obtain the blood pressure parameters of the object to be tested at the first time.

[0191] For example, Um may be the fluctuation peak value obtained by the fingerprint recognition module, Pm may be the pressure parameter corresponding to Um, and Pm may be recorded as the average blood pressure.

[0192] The systolic pressure Ps may be equal to the pressure parameter corresponding to the first fluctuation value Us obtained by multiplying the fluctuation peak value Um by the first relative coefficient Ks. The first relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the first relative coefficient Ks may be 0.5.

[0193] The diastolic pressure Pd may be equal to the pressure parameter corresponding to the second fluctuation value Ud obtained by multiplying the fluctuation peak value Um by the second relative coefficient Kd. The second relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the second relative coefficient Ks may be 0.8.

[0194] The blood pressure parameter result at the first time obtained by the first blood pressure detection method is used as a reference result to calibrate the second blood pressure detection method.

[0195] The pulse wave parameters at the distal end of the subject's limbs are compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is inversely proportional to the change in blood pressure, the blood pressure of the subject can be calculated based on the pulse wave conduction time method. The calculation formula is as follows:

[0196] Blood pressure = A / pulse transit time + B

[0197] Among them, A and B are constants.

[0198] Among them, A and B are constants, and because the values ​​of A and B are related to the physical constitution of the object to be tested, the benchmark results can be substituted into the above calculation formula, and then the intermediate constants can be obtained by data fitting, and the values ​​of the intermediate constants can be configured as the values ​​of A and B.

[0199] During the blood pressure parameter detection process at the second time, that is, during the blood pressure parameter detection process after calibration is completed, the intermediate constant can be configured as a preset parameter, and the object to be measured can use the second blood pressure detection method calibrated according to the physique of the object to be measured, thereby realizing self-calibration of the detection component 100 for the second blood pressure detection method.

[0200] Since the method of obtaining blood pressure through pulse fluctuation parameters and pressure parameters requires continuous pressing of the detection part 10, while the method of obtaining blood pressure through pulse fluctuation parameters and electrocardiogram parameters does not require continuous pressing, the operation of the second blood pressure detection method is simpler and easier for users to operate.

[0201] Figure 8 is a flow chart of a detection method according to an exemplary embodiment. Figure 8 As shown, the detection method may include:

[0202] S11: detecting a pressing operation of the object to be tested on the detection part;

[0203] S12: Displaying the pressure parameter of the pressing operation and the preset pressure parameter, so that the object to be detected applies a force to the detection part according to the preset pressure parameter.

[0204] When the subject to be tested performs a pressing operation on the detection part, by displaying the pressure parameter of the pressing operation and the preset pressure parameter, the subject to be tested can apply pressure to the detection part according to the preset pressure parameter, so that the pressure parameter data of the detection part that continuously changes according to the preset pressure parameter can be obtained. Exemplarily, the change trend of the preset pressure parameter can be to increase first and then decrease.

[0205] Exemplarily, a recommended pressure curve that conforms to a preset pressure range and an actual pressure curve reflecting the pressure applied to the object to be tested can be simultaneously displayed to the object to be tested, so that the preset pressure range can clearly know the pressure applied to the detection part, and the pressure applied can be adjusted according to the difference between the recommended pressure curve and the actual pressure curve.

[0206] However, the present disclosure is not limited thereto, and the difference between the current pressure and the preset pressure range may also be fed back to the object to be measured by voice broadcast, vibration frequency, vibration amplitude, sound volume, light brightness, etc., so that the object to be measured can adjust the pressure applied to the object to be measured according to the feedback information. The first detection parameter may include a pulse parameter of the object to be measured, and illustratively, the first detection parameter may include a pulse fluctuation parameter and a pressing area parameter. The physiological parameter may be a blood pressure parameter of the object to be measured.

[0207] When the detection component 100 is in the first time, the pulse fluctuation parameters of the distal limbs of the object to be detected can be obtained through the fingerprint recognition module, the heart rate parameters of the object to be detected can be obtained through the electrocardiogram detection module, and the pressure parameters of the detection part 10 can be obtained through the pressure detection module.

[0208] According to the parameter results obtained in the first time, the detection component 100 can perform the first blood pressure detection method.

[0209] When the subject is undergoing blood pressure monitoring, the subject can press the detection component 100 according to the recommended pressure, thereby obtaining a pressure change curve that first increases and then decreases.

[0210] When the fingerprint recognition module is an ultrasonic fingerprint recognition module, the ultrasonic fingerprint recognition module can use an ultrasonic transducer to emit an ultrasonic pulse signal, then receive the reflected ultrasonic pulse, calculate the position of the reflection interface according to the time delay of the received pulse signal, and realize the ranging function. The fingerprint recognition module is attached to the skin surface of the object to be measured, and ultrasonic pulses are continuously emitted to the object to be measured, and the reflected echo signal is received, so that the pulse fluctuation parameters generated by the pulse on the skin surface of the object to be measured can be obtained.

The photoelectric fingerprint recognition module converts the received light signal into an electrical signal, and after amplification and filtering, the pulse fluctuation parameter is obtained.

[0212] The pressure detection module can record the pressure parameters in real time. The detection component 100 can calculate the pressing pressure parameters according to the pressing area parameters and the pressure parameters, and then combine the fluctuation value, the pressing pressure parameters and the relative coefficient to obtain the blood pressure parameters of the object to be tested at the first time.

[0213] For example, Um may be the pulse fluctuation peak value obtained by the fingerprint recognition module, Pm may be the pressure parameter corresponding to Um, and Pm may be recorded as the average blood pressure.

[0214] The systolic pressure Ps may be equal to the pressure parameter corresponding to the first fluctuation value Us obtained by multiplying the fluctuation peak value Um by the first relative coefficient Ks. The first relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the first relative coefficient Ks may be 0.5.

[0215] The diastolic pressure Pd may be equal to the pressure parameter corresponding to the second fluctuation value Ud obtained by multiplying the fluctuation peak value Um by the second relative coefficient Kd. The second relative coefficient may be obtained by comparing and calibrating with other blood pressure measurement methods. For example, the second relative coefficient Ks may be 0.8.

[0216] The blood pressure parameter result at the first time obtained by the first blood pressure detection method is used as a reference result to calibrate the second blood pressure detection method.

[0217] The pulse wave parameters at the distal end of the subject's limbs are compared with the heart rate parameters to obtain the pulse conduction time. Since the pulse conduction time is inversely proportional to the change in blood pressure, the blood pressure of the subject can be calculated based on the pulse wave conduction time method. The calculation formula is as follows:

[0218] Blood pressure = A / pulse transit time + B

[0219] Among them, A and B are constants.

[0220] Among them, A and B are constants, and because the values ​​of A and B are related to the physical constitution of the object to be tested, the benchmark results can be substituted into the above calculation formula, and then the intermediate constants can be obtained by data fitting, and the values ​​of the intermediate constants can be configured as the values ​​of A and B.

[0221] During the blood pressure parameter detection process at the second time, that is, during the blood pressure parameter detection process after calibration is completed, the intermediate constant can be configured as a preset parameter, and the object to be measured can use the second blood pressure detection method calibrated according to the physique of the object to be measured, thereby realizing self-calibration of the detection component 100 for the second blood pressure detection method.
