Description

Technical Field

[0001] The present invention belongs to the technical field of blood pressure measurement, and in particular relates to a blood pressure monitoring device, method and system based on a flexible tactile sensor. Background Art

[0002] A wristwatch-type blood pressure monitor, also known as an electronic sphygmomanometer, is a portable medical device that combines electronic technology with the principle of indirect blood pressure measurement to achieve real-time monitoring and recording of blood pressure. A traditional wristwatch-type blood pressure monitor includes a flexible strap, a pressure sensor, and a central control digital display unit. The flexible strap is detachably wrapped around the operator's wrist, and the pressure sensor is arranged on the inner wall of the flexible strap facing the user's wrist. The pressure sensor is electrically connected to the central control digital display unit. After the operator wears it, the central control digital display unit drives the pressure sensor to monitor the pressure of the artery under the skin of the operator's wrist. The expansion or contraction of the arterial wall caused by the flow of arterial blood is called pulse. The pulse acts on the sensing end of the pressure sensor through the skin of the wrist, so that the pressure sensor can obtain the pressure value and pulse frequency generated by a single pulse.

[0003] In the above scheme, the position of the pressure sensor is fixed. After the watch strap is worn on the patient's wrist, it needs to be locked by adjusting the buckle / magnetic buckle. In some schemes, the watch strap is provided with an inflatable structure, and the pressure sensor is pressed against the patient's wrist through the airbag. However, since the sensor position is fixed, before the strap is locked, the patient or the wearer is not clear whether the pressure sensor can be accurately pressed on the preset pulse position. The locked strap also has a fixed structure. Even if driven by the airbag, the pressure sensor only moves along the deviated position and cannot achieve the sensor position correction adjustment.

[0004] Therefore, the defect of the existing solution is that the pressure sensor deviates from the preset pulse position for pressure detection, resulting in a decrease in the accuracy of pulse feeling and errors in the pulse feeling results; even if the wearer, operator or patient finds that there is a deviation in the pulse feeling position, they can only disassemble the watch and put it on again, and there is no way to determine whether the pulse feeling position after being put on again is accurate, which greatly reduces its practicality. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a blood pressure monitoring device, method and system based on a flexible tactile sensor to solve the problem that the sensor position of the wristwatch-type blood pressure monitor in the prior art is fixed and cannot realize sensor position correction adjustment, and it is easy to deviate from the preset pulse position for pressure detection, resulting in a decrease in the accuracy of pulse feeling and errors in the pulse feeling results.

[0006] One solution of the present invention provides a blood pressure monitoring device based on a flexible tactile sensor, comprising a flexible strap and an annular housing;

[0007] The annular housing is arranged on the flexible strap; the annular housing includes a pressure sensor assembly and a driving wheel set, the pressure sensor assembly is arranged on the inner end surface of the flexible strap facing the user's wrist, the driving wheel set is arranged between the pressure sensor assembly and the annular housing, and the driving wheel set is used to adjust the relative position of the pressure sensor assembly on the inner end surface. The pressure sensor assembly at least includes a pressure sensor chip and an FPCB board, the pressure sensor chip is arranged on the side of the FPCB board facing the user's wrist; the pressure sensor chip is arranged in a plurality of groups, and the plurality of groups of pressure sensor chips are arranged in an array to form a matrix monitoring area of ​​a preset area. The inner end surface of the annular shell is provided with an arc-shaped slide groove and an arc-shaped slider limited inside the arc-shaped slide groove, and the annular shell and the arc-shaped slider form a double-layer ring structure with the same center of circle; the driving wheel group is arranged between the arc-shaped slide groove and the arc-shaped slider, and the driving wheel group drives the arc-shaped slider to slide along the arc-shaped slide groove when running, so as to make the matrix monitoring area cover the position with the highest pulse intensity; the pressure sensor assembly is arranged on the arc-shaped slider; an airbag assembly is arranged in the arc-shaped slider, and the airbag assembly is located between the arc-shaped slider and the pressure sensor chip, so as to support the pressure sensor assembly when the airbag assembly is inflated.

[0008] It can be understood that in this solution, a matrix monitoring area formed by multiple groups of pressure sensor chips is used to achieve large-area pulse monitoring, and then confirm the pulse position. After confirming the source of the pulse, the monitoring data of the sensor chip at the corresponding position is screened. When performing data analysis, the data processed by the system has a high degree of correlation, thereby improving the monitoring accuracy.

[0009] In addition, the outer shell includes a double-layer ring structure, and the arc-shaped slider can drive multiple groups of pressure sensor chips to rotate and fine-tune when rotating and moving, thereby moving the matrix monitoring area to a preset position. The driving direction is adjusted in real time according to the detection results of the matrix monitoring area until the matrix monitoring area covers the position with higher pulse signal intensity.

[0020] Please refer to Figure 1-Figure 3, one embodiment of the present invention provides a blood pressure monitoring device based on a flexible tactile sensor, comprising a flexible strap 1 and an annular housing 2;

[0021] The annular housing 2 is arranged on the flexible strap 1;

[0022] The annular housing 2 includes a pressure sensor assembly 3 and a driving wheel group 4. The pressure sensor assembly 3 is arranged on the inner end surface of the flexible strap 1 facing the user's wrist. The driving wheel group 4 is arranged between the pressure sensor assembly 3 and the annular housing 2. The driving wheel group 4 is used to adjust the relative position of the pressure sensor assembly 3 on the inner end surface.

[0023] It can be understood that in this embodiment, a matrix monitoring area formed by multiple groups of pressure sensor chips 31 is used to achieve large-area pulse monitoring, and then confirm the pulse position. After confirming the source of the pulse, the monitoring data of the sensor chip at the corresponding position is screened. When performing data analysis, the data processed by the system has a high degree of correlation, thereby improving the monitoring accuracy.

[0024] In one embodiment, the pressure sensor assembly 3 at least includes a pressure sensor chip 31 and an FPCB board 32, and the pressure sensor chip 31 is arranged on a side of the FPCB board 32 facing the wrist of the user;

[0025] The pressure sensing chips 31 are provided in a plurality of groups, and the plurality of pressure sensing chips 31 are distributed in an array to form a matrix monitoring area of ​​a preset area.

[0026] In this embodiment, the pressure sensor assembly 3 is arranged on the end surface of the annular housing 2 facing the user's wrist. An airbag assembly 6 is arranged in the annular housing 2. When the airbag is expanded, the pressure sensor chip 31 is in close contact with the skin of the user's wrist.

[0027] It can be understood that multiple groups of pressure sensor chips 31 are distributed in an array to form a monitoring area of ​​a certain area on the inner ring surface of the annular shell 2. During the monitoring process, all the pressure sensor chips 31 in the monitoring area are started and operated for a period of time. The system analyzes and marks the pressure sensor chip 31 with the highest force, and records the monitoring parameters of all the pressure sensor chips 31, and filters out the data of the marked pressure sensor chips 31 for blood pressure monitoring result analysis.

[0028] In one embodiment, the inner end surface of the annular housing 2 is provided with an arc-shaped slide groove 21 and an arc-shaped slider 5 limited inside the arc-shaped slide groove 21, and the annular housing 2 and the arc-shaped slider 5 form a double-layer ring structure with the same center.

[0029] The driving wheel set 4 is arranged between the arc-shaped slide groove 21 and the arc-shaped slide block 5. When the driving wheel set 4 is in operation, it drives the arc-shaped slide block 5 to slide along the arc-shaped slide groove 21, so as to make the matrix monitoring area cover the position with the highest pulse intensity;

[0030] The pressure sensor assembly 3 is arranged on the arc-shaped slider 5;

[0031] An airbag assembly 6 is disposed in the arc-shaped slider 5 . The airbag assembly 6 is located between the arc-shaped slider 5 and the pressure sensor chip 31 and is used to prop up the pressure sensor assembly 3 when the airbag assembly 6 is inflated.

[0032] In this embodiment, based on the pulse monitoring signal fed back from the detection area of ​​the array pressure sensor chip 31, the direction of the pressure source can be calculated and analyzed, and the driving wheel group 4 drives the arc slider 5 to rotate so that the detection area can move and cover the position with the highest pulse intensity.

[0033] It can be understood that an airbag structure is provided in the flexible strap 1. When the user wears the flexible strap 1 on the wrist, the airbag structure can be inflated to increase the thickness of the flexible strap 1; when the airbag is inflated, the pressure sensing chip 31 is in close contact with the skin of the user's wrist.

[0034] In one embodiment, the pressure sensing chip 31 is a MEMS pressure sensing chip or a FPCB touch sensing panel;

[0035] The end of the pressure sensing chip 31 facing the user's wrist is installed in a flexible conductive layer, and the flexible conductive layer is provided with a plurality of preset installation holes for installing the pressure sensing chip 31.

[0036] The array structure of the granular MEMS pressure sensor chip (0.4mm thickness) can easily cause scratches and wear on the wrist if it comes into direct contact with the user, affecting the wearing experience.

[0037] In this embodiment, the contact area of ​​the monitoring area is increased through array design, and the pressure generated by the pressure sensor chip 31 on the wrist is reduced; a flexible conductive layer structure is further added. The flexible conductive layer expands the contact area of ​​the MEMS pressure sensor chip on the wrist while ensuring pressure conduction, thereby further reducing the pressure of the pressure sensor chip 31 and improving wearing comfort.

[0038] In an application scenario of this embodiment, the flexible conductive layer is made of PU or PA material.

[0039] In one embodiment, strap buckles 7 are provided at both ends of the flexible strap 1, and the strap buckles 7 enable the flexible strap 1 to be detachably wrapped around the wrist of the user's radial artery;

[0040] In this embodiment, the strap buckle 7 enables the flexible strap 1 to be detachably wrapped around the wrist of the user's radial artery, so that the pressure sensor assembly 3 and the annular slider fit tightly against the user's wrist, ensuring that the pressure sensor assembly 3 can obtain pressure parameters.

[0041] In one embodiment, a digital display dial 8 is further provided on the annular housing 2 , and the digital display dial 8 is electrically connected to the pressure sensor assembly 3 .

[0042] It can be understood that the digital display dial 8 is arranged on the annular housing 2, and the blood pressure monitoring monitored by the pressure sensor chip 31 is visualized through the digital display dial 8, so as to facilitate the intuitive display of the blood pressure monitoring results.

[0043] In one embodiment, a blood pressure monitoring method based on a flexible tactile sensor is also provided, which can be used in a blood pressure monitoring device based on a flexible tactile sensor described in any one of the above embodiments, including:

[0044] Step S10, acquiring monitoring parameters of a plurality of pressure sensor assemblies at a first preset time as a first pressure parameter, wherein the plurality of pressure sensor assemblies form a matrix monitoring area;

[0045] Step S20, arranging the first pressure parameters in descending order, marking the pressure sensor components with preset rankings based on the sorting results, and outputting the serial number data of the marked pressure sensor components;

[0046] Step S30: based on the number data, obtaining the monitoring parameter of the marked pressure sensor assembly at the second preset time as a second pressure parameter;

[0047] Step S40: obtaining a blood pressure monitoring result based on the second pressure parameter analysis, and visually displaying the blood pressure monitoring result through a digital display dial.

[0048] In this embodiment, the pressure sensor chips are distributed along the matrix, and each pressure sensor chip has a corresponding number, such as: N1, N2, N3, N4... After wearing, all sensor chips can obtain pressure parameters. Based on the intensity distribution of the pressure parameters, it is identified whether the monitoring area covers the pulse position. If it is identified that the monitoring area deviates from the pulse position, the relative position of the pressure sensor chip is adjusted. If the monitoring area just covers the pulse position, the pressure parameter obtained by the sensor chip close to the pulse position is larger. In the current pressure parameter sorting of all sensor chips: N9 is the maximum value. The pressure parameter comparison and sorting unit sorts all chips and transmits the sequence to the chip marking unit. The chip marking unit marks N9 and the chips around N9; after running for a period of time, the pressure parameter storage unit feeds back all pressure parameters to the control module, and the control module screens the pressure parameters of the required sensors through the marking to perform blood pressure and pulse data analysis.

[0049] It can be understood that this embodiment helps to improve monitoring accuracy and prevent the influence of abnormal data by accurately analyzing the pressure data of the pulse position.

[0050] In one embodiment, the method further includes identifying the alignment of the matrix monitoring area, specifically including:

[0051] Step S11, analyzing and obtaining the vector direction of the monitoring parameters of the matrix monitoring area, and outputting the vector change direction;

[0052] Step S12, generating a correction instruction based on the vector change direction, wherein the correction instruction includes a driving roller control instruction and an air pump control instruction;

[0053] Step S13, executing the deviation correction instruction to move the pressure sensor assembly along a preset direction;

[0054] Step S14: Acquire the monitoring parameter of the pressure sensor assembly after the movement as the first pressure parameter.

[0055] In this embodiment, the monitoring area does not cover the pulse position. At this time, the pressure parameters of all sensor chips change in a vector direction, and the vector direction along which the pressure parameters increase is the direction in which the pulse starts. At this time, the control module drives the air pump to deflate slightly, so that the fit between the pressure sensor chip and the annular slider and the user's wrist decreases. The control module drives the roller to rotate, so that the slider moves a preset stroke in a preset direction (the stroke is a fixed preset value) or forms a single movement through a PID algorithm calculation, so that the sensor chip adjusts its position. After the movement is completed, the air pump is re-inflated, and the sensor chip is driven to fit closely to the wrist through the airbag to obtain the pressure parameters.

[0056] Repeat the above steps until the monitoring area appears as follows: Figure 2 As shown, N9 has the largest value, and the values ​​of N5, N6, N7, N8, N10, N11, N12, and N13 are close to the parameter distribution pattern, which means that the monitoring area has covered the pulse onset position, the positioning is completed, and step S10 is started to perform analysis and monitoring.

[0057] In one embodiment, generating the correction instruction based on the vector change direction includes generating a driving roller control instruction based on a fixed preset value or obtaining the driving roller control instruction based on a PID algorithm calculation;

[0058] The step of obtaining the driving roller control instruction based on the PID algorithm includes:

[0059] Obtain mobile trip data for trip training and output trip training results;

[0060] Based on the stroke training result, a proportionality coefficient between the stroke movement time and the maximum pressure parameter is calculated;

[0061] The driving roller control instruction is calculated and obtained through the vector change direction and the proportional coefficient.

[0062] The correction instruction is executed to realize the movement of the pressure sensor assembly in a preset direction. The commonly used method is that the fixed amount of stroke has the problems of long adjustment time and efficiency, and repeated movement can easily cause discomfort to the wearer.

[0063] In this embodiment, the stroke training method includes:

[0064] The roller angular velocity V is calculated and fixed by the driving source (pneumatic or motor drive), the slider moving angular stroke is D, VT = D, T is one of the variables that the control system needs to obtain through PID algorithm training;

[0065] Set the distance between the center of the monitoring area and the pulse source as D1, and adjust the size of D, and record it in sequence as D1, D2, D3, D4...

[0066] Training data 1: through the arrangement and combination of pressure parameters recorded by all sensor chips, record the vector direction formed by them, and record the maximum pressure parameter P1; according to the slider driving method described in the attached figure, record the time T1 required for the slider to drive the monitoring area to move D1;

[0067] Training data 2: through the arrangement and combination of pressure parameters recorded by all sensor chips, record the vector direction formed by them, and record the maximum pressure parameter P2; according to the slider driving method described in the attached figure, record the time T2 required for the slider to drive the monitoring area to move D2;

[0068] Training data 3: Repeat the above steps;

[0069] Training data N: Repeat the above steps.

[0070] The proportional coefficient K between T and P is obtained by analyzing multiple sets of data.

[0071] In this embodiment, the appropriate time T can be calculated according to the size and direction of the pulse intensity P and the coefficient K of time and pressure intensity. Under the premise of setting a fixed speed V, the slider can be moved an appropriate distance D, thereby aligning the center of the monitoring area with the pulse starting position, and completing the positioning with a single movement.

[0072] In one embodiment, a blood pressure monitoring system based on a flexible tactile sensor is provided, which can be used in any one of the blood pressure monitoring methods based on a flexible tactile sensor described in the above embodiments, including:

[0073] A parameter storage unit, used to obtain monitoring parameters of a plurality of pressure sensor assemblies at a first preset time as a first pressure parameter, wherein the plurality of pressure sensor assemblies form a matrix monitoring area;
