Fig. 2 shows an application object 100 of a pulse data detection system, or at least a pulse data detection apparatus 200. In this embodiment, the application object 100 may be a wrist of a patient, and specifically may be a cunkoradial artery on the wrist of the patient. At least one region to be measured 10 is distributed on the application object 100, and in the foregoing embodiment, three regions to be measured 10 are specifically arranged in the first direction W1 in which the arm extends, and may be a size region 10A, a close region 10B, and an inch region 10C corresponding to three positions, i.e., a "size" position, a "close" position, and a "inch" position, respectively. The first direction W1 may be defined as a pulse length direction, and the second direction W2 perpendicular thereto may be defined as a pulse width direction, and based on this, the relative positions of the size region 10A, the off region 10B, and the size region 10C in the second direction W2 are approximately equal. Based on the location of the "size" part, the "close" part, and the "inch" part on the wrist or arm in traditional Chinese medicine, for example, the size area 10A, the close area 10B, and the inch area 10C are located on the upper side of the midline of the arm W2 in the second direction, as would be expected by one skilled in the art.
Referring to fig. 1, 2, 3 and 5, an embodiment of the invention provides a pulse data detection device 200 for acquiring pulse data of an area to be detected 10, which may be disposed in a pulse data detection system. Specifically, the pulse data detecting apparatus 200 includes a sensing component 2 disposed near the area to be measured 10 on the application object 100 for acquiring pulse data. Preferably, the sensing assembly 2 includes a time sensor 21 and a space sensor 22, and the time sensor 21 and the space sensor 22 have a relative positional relationship such that a detection range of the space sensor 22 and a detection range of the time sensor 21 at least partially overlap on the side of the area to be measured 10 and form an overlap detection area 23. Thus, the pulse data detection at different time and the pulse data detection at different positions can be simultaneously or sequentially carried out on the parts in the overlapped detection area 23, so that the detection effect of combining self comparison and mutual comparison is achieved.
Further, the overlapping detection area 23 formed by the single group of the time sensor 21 and the space sensor 22 covers at least one of the areas to be detected 10, so as to improve the detection effect of the areas to be detected 10. Based on the foregoing embodiment in which the regions to be measured 10 are configured as the size region 10A, the close region 10B, and the size region 10C, the sensing elements 2 may be provided in three corresponding to the above three regions, respectively, and have a positional relationship in which the relative positions in the first direction W1 are arranged in order and the relative positions in the second direction W2 are approximately equal.
In the detection process, the sensing assembly 2 collects the pulse data on the corresponding region to be detected 10 by abutting and the like. Specifically, the time sensor 21 is configured to detect a first pressure data set and a time data set corresponding to each other at least two different times, and the space sensor 22 is configured to detect a second pressure data set corresponding to a preset position data set at least two different positions in the area to be measured 10.
The time data set includes multiple time data, and the time sensor 21 respectively collects the pressure data of the region to be measured 10 at the time corresponding to the multiple time data to form a first pressure data set. In an embodiment, the time data set may be preset, and the present invention does not limit the preset manner, and may be implemented by setting parameters such as frequency and duty ratio. The pressure data acquired by the time sensor 21 preferably represents the pulse change of the entire region 10.
Further, the position data group includes position data corresponding to a plurality of positions in the region to be measured 10, and the spatial sensor 22 collects the pressure data at the plurality of positions, respectively, to form a second pressure data group. In one embodiment, the position data may be coordinate data formed by establishing a coordinate system with an origin at any point on any one side of the region to be measured 10, for example, in an embodiment where the region to be measured 10 is set to be a rectangle, a start point (a point at the upper left corner in fig. 2) of the region to be measured in the first direction W1 and the second direction W2 may be used as the origin of coordinates, and for example, in an embodiment where the region to be measured 10 is set to be a circle, a center of the region to be measured 10 may be used as the origin of coordinates. Furthermore, the pressure data acquired by the spatial sensor 22 preferably represent the pulse condition at different positions of the area 10 to be measured at a single moment.
The overlapping detection area 23 covers at least the region to be measured 10, and represents the area size and the positional relationship of the coverage areas of the detection areas of the two on the application object 10. For example, in the embodiment where the two shapes are the same or similar, the area of the coverage area of the overlapped detection region 23 is greater than or equal to the area of the coverage area of the region to be measured 10; in the embodiment where the region to be measured 10 is rectangular and the overlap detection region 23 is circular, the coverage area of the overlap detection region 23 is at least the circumscribed circle of the coverage area of the region to be measured 10; in the embodiment where the area to be measured 10 is circular and the overlapping detection areas 23 are rectangular, the coverage area of the area to be measured 10 is at most the largest circle inside the coverage area of the overlapping detection areas 23.
Further, the pulse data detecting apparatus 200 further includes a pressing component 4, wherein the pressing component 4 is disposed on a side of the sensing component 2 away from the region to be measured 10, and is preferably configured to selectively apply pressure to the sensing component 2 according to the pressure action information, so as to adjust at least a relative distance between the sensing component 2 and the region to be measured 10 in a direction perpendicular to the region to be measured 10. Therefore, the state of the pressing component 4 can be regulated and controlled through the pressure action information, so that the relative position between the sensing component 2 and the area to be detected 10 is influenced, the matching and the de-matching are realized, and the applied pressure is adjusted.
Regarding the direction of the relative displacement of the sensing assembly 2 and the region to be measured 10 after being adjusted, the region to be measured 10 is disposed on the surface of the application object 100, the first direction W1 may show the pulse length of the patient, and the second direction W2 may show the pulse width of the patient, based on which the direction of the relative displacement may be a third direction perpendicular to both the first direction W1 and the second direction W2.
The pressing component 4 adjusts the relative position, the angle of the driving mode can be the transmission of mechanical components such as electric drive, magnetic drive, pneumatic or connecting rods, and the like, and the angle of the initial position can be determined and restored by arranging structures such as a fixed seat, a lifting platform, a clamping jaw and the like. In a preferred embodiment, the pressing assembly 4 comprises a fixing member 41 and an air bag 42 for fixing the initial position and state of the sensing assembly 2 and pneumatically adjusting the relative position between the sensing assembly 2 and the region to be measured 10, respectively.
Specifically, the fixing member 41 and the sensing element 2 are respectively fixed on two sides of the air bag 42, the fixing member 41 is used for defining the relative position relationship between the pulse data detection device 200 and the region to be detected 10, and the air bag 42 is correspondingly configured to receive the gas input, so as to drive the sensing element 2 to move towards the direction close to the region to be detected 10; the air bag 42 is exhausted to drive the sensing assembly to move away from the region to be measured. Preferably, the gas input is provided by a device or module separate from pressure applicator assembly 4 and sensing assembly 2, and in some embodiments may be provided directly under the control of a device or module provided in sensing assembly 2 or pressure applicator assembly 4. Therefore, on one hand, the sensing assembly 2 can be sufficiently contacted with the region 10 to be tested and acquire information by adjusting parameters such as the volume of the application object 100, and on the other hand, the magnitude of the applied pressure can be adjusted according to the test requirement, and data generated by pulse reaction under different pressures can be acquired in a targeted manner.
The fixing member 41 may be specifically configured to be a strip shape, so that a user can at least sleeve the fixing member 41 on two opposite sides of the region to be measured 10 to fix the relative positions. For example, in one embodiment, the fixing member 41 may include a first fixing member and a second fixing member which are provided in segments, and are respectively provided at opposite sides of the cooperating structure of the air bag 42, the time sensor 21 and the space sensor 22.
Further, the fixing member 41 is preferably formed in a shape of a band or a bracelet, so that the wrist portion of the application object 100 can pass through a ring-shaped structure surrounded by the fixing member 41 in a band shape, thereby providing wearable pulse detection for the user. Correspondingly, the fixing member 41 may be provided with a wavy structure, and the concave-convex portion on the wavy structure may damp and limit the application object 100, so as to enhance the fixing effect; in order to adjust the diameter of the ring structure, the fixing member 41 may further be provided with a movable hinge, and when adjusting the diameter, the position of the fixing member 41 on one side of the movable hinge may be adjusted to be extended and folded on the other side of the movable hinge, so as to influence the diameter by reducing the circumference of the fixing member 41, so as to meet the requirements of different application objects 100.
With respect to the cooperative structure of the time sensor 21, the space sensor 22 and the air bag 42, in one embodiment, the time sensor 21 and the space sensor 22 are configured as a film pressure sensor, which can be adapted to adjust the shape of the air bag 42 according to the relaxation of the air bag, thereby providing a more comfortable wearing experience and a more accurate detection effect. Correspondingly, the air bag 42 is arranged to be in an ellipsoidal shape at least when being inflated, the long axis of the air bag 42 is parallel to the region to be measured 10, and the surface with smaller curvature of the air bag 42 faces at least the region to be measured 10, so that the pressing of the finger belly of a human finger can be simulated, and the influence on the data content due to the form error during detection can be prevented. It is understood that the balloon 42 may be in an ellipsoidal shape at least when inflated, may be in other shapes when not inflated, may also be in an ellipsoidal shape when not inflated, may adjust the distance between the sensing element 2 and the region to be measured 10 by increasing the ratio of the minor axis to the major axis thereof through inflation, or may adjust the distance by changing the shape thereof through inflation.
It should be noted that, in order to achieve the intended technical effect, the combination of the air bag 42 and the time sensor and the space sensor configured as a soft material, such as a thin film pressure sensor, should have a substantially ellipsoidal shape resembling the belly of a finger, at least when the sensing element 2 is in contact with the region 10 to be measured and is detecting. In another embodiment, the air bag 42 can be compressed to reduce the volume occupation when the pulse data detecting device 200 is not activated, and is filled with 30mHg of gas by default at the start of activation to keep the finger-belly appearance at the start of activation.
The time sensor 21 and the space sensor 22 are directly or indirectly attached to the air bag 42, and the ellipsoidal shape is realized by the inflated shape of the air bag 42. Of course, in one embodiment, the sensing assembly 2 can further comprise an ellipsoidal housing 20, and the air bag 42, the time sensor 21 and the space sensor 22 are disposed between the upper half and the lower half of the ellipsoidal housing 20. After the air bag 42 is inflated, the lower half portion disposed near the region to be measured 10 moves toward the region to be measured 10, and the lower half portion is fixed in shape, so that the finger belly shape can be always simulated after the lower half portion abuts against the region to be measured 10.
In one embodiment, referring to fig. 1, the sensing assembly 2 can be used to implement at least one of the functions of receiving the gas input from the adjustment air bag 42, displaying and outputting the pulse data collected by the time sensor 21 and the space sensor 22, and even storing, computing, analyzing and the like the pressure data. Based on this, the sensing assembly 2 may further include a display module 24, which may be configured to receive at least one of a touch operation or a key operation, and is preferably configured to have a poor arc-shaped contact surface at least at a side close to the application object 100. The center of the minor arc is located at one side of the application object 100, so as to form an annular structure suitable for the application object 100 to penetrate together with other parts of the fixing member 41.
On one hand, for the inferior arc-shaped contact surface, electronic components for realizing other functions can be integrated, for example, components for detecting other body parameters can be integrated, so that the detection of parameters such as heart rate, blood oxygen and blood sugar is completed while the pressure data is acquired. On the other hand, the surface of the display module 24 facing away from the application object 100 is preferably configured as a flat surface in order to improve the user operation experience and reduce the probability of misoperation. Of course, it is contemplated that other elements may be integrated on the flat surface, or a technical solution formed by wireless charging, solar charging modules, etc., and will not be described herein.
As shown in fig. 1, 3, 4 and 5, for the gas input received by the airbag 42, on one hand, because there is a corresponding relationship between the gas input and the gas output, a corresponding gas output mode can be obtained with reference to the specific embodiment of the gas input provided in the present invention, and the present invention is not described again. On the other hand, when the gas received by the airbag 42 is an internal gas, the internal gas may be circulated by the fixing member 41 cooperating therewith, or the fixing member 41 may communicate with the outside to suck and discharge the gas; when the gas input received by the balloon 42 is external gas, the pressurizing assembly 4 may further include a gas-guiding tube 43, and the gas-guiding tube 43 communicates the balloon 42 with the external device for supplying and receiving gas through the connecting terminal 431.
On one hand, the connection terminal 431 may have both the circular truncated part and the cylindrical part, balancing gas transmission speed and safety. On the other hand, in the embodiment where the sensing assembly 2 corresponds to the balloon 42 and three sets are arranged at intervals along the first direction W1, at least three air ducts 43 may be correspondingly arranged to adapt to the different pressing requirements of the size region, the close region and the inch region.
The means for supplying and receiving gas is preferably a control module 51 comprised in the pulse data detection device 200, the control module 51 being connected to the pressure application assembly 4 and configured to output pressure action information to the pressure application assembly 4 in response to a control signal.
Specifically, on one hand, the control module 51 may be configured integrally with the sensing assembly 2, the pressing assembly 4, and the like, and the air duct 43 is hidden in the fixing member 41, so that the inhaling and discharging of the external air, and the transceiving of the control signal may be integrated into the aforementioned components such as the display module 24; the control module 51 may be provided separately from the sensing assembly 2, the pressurizing assembly 4, etc., to independently receive the control signal and output or suck the gas by means of the air pump, etc. On the other hand, the control signal may be directly input to the control module 51 by the user, or may be analyzed and executed by forwarding the input signal to the control module 51 after being input to other upper computers, mobile terminals, the display module 24 or other devices by the user. The pressure action information preferably includes an output gas amount representing the pressure, and specifically, after receiving the control signal, the control module 51 invokes a preset relational expression to convert the expected pressure data carried in the control signal into output gas amount data, and controls the air pump to suck in gas and output the gas to the air guide tube 43, or controls the air pump to receive the gas from the air guide tube 43 and output the gas to the external environment.
Based on this, the control module 51 may include a switch portion 510 that controls start and stop, and an operation portion 511 that receives a control action input by a user. The operating part 511 may be formed as a touch screen or a keyboard to receive input of data information, and may also be formed to include a preset gear position and a control key corresponding to the sensing member 2. The user can press or call the air bag 42 corresponding to the sensing assembly 2 to be adjusted, and then select the pressure regulation requirement for the air bag 42 to form a control signal, so that the control module 51 can analyze and output the pressure action information corresponding to the air bag 42.
In one embodiment, the control module 51 is used to form a feedback adjustment to the pressure output. For example, the control module 51 may be connected to at least one of the time sensor 21 and the space sensor 22, and the control module 51 is configured to receive the pressure detection values from the time sensor 21 and the space sensor 22 and adjust the output of the pressure action information according to the pressure setting value and the pressure detection value carried in the control signal. Therefore, on one hand, the pressure detection functions of the time sensor 21 and the space sensor 22 are multiplexed, and the increase of the structural complexity caused by the addition of an independent pressure detection device can be avoided; on the other hand, the control module 51 adaptively adjusts the pressure operation information output by comparing the values of the pressure set value and the pressure detection value.
In the traditional Chinese medicine technology, the cunkoradial artery is preferably applied with three forces of floating, middle and sinking corresponding to the 'chi', the 'guan' and the 'cun' positions. Based on this, the distribution of data may be made dependent on the pressure action information, which may include, for example, first action information, second action information, and third action information. The first action information corresponds to the exerted 'floating' force and carries at least one group of first pressure data in the interval of 30mmHg to 80mmHg, and the first action information is output to the air bag 42 corresponding to the ruler area to form pressure output corresponding to the first pressure data; the second action information is corresponding to the applied middle force and carries at least one group of second pressure application data in the interval of 80mmHg to 170mmHg, and the second action information is output to the air bag 42 corresponding to the closed area to form pressure output corresponding to the second pressure application data; the third action information corresponds to the applied sinking force and carries at least one group of third pressure application data in the interval of 170mmHg to 210mmHg, and the third action information is output to the air bag 42 corresponding to the closed area to form pressure output corresponding to the third pressure application data.
In view of the above problem of unit mismatch of the pressure data carried in various information, the pulse data detecting device 200 may further include a standardization module 52, which may be disposed at any one of the control module 51, the sensing assembly 21 or the pressurizing assembly 4. The normalization module 52 is connected to at least the time sensor 21 and the space sensor 22, and is configured to perform pressure unit conversion and data normalization on the first pressure data set and the second pressure data set respectively collected by the time sensor 21 and the space sensor 22, so as to convert the results detected by the two sensors into pressure units such as Pa, kPa, or mmHg, and eliminate inconsistencies inside the time sensor 21, inside the space sensor 22, or between the time sensor 21 and the space sensor 22. The way to eliminate the inconsistency may be to reduce the dispersion of the data by calibration.
Preferably, the normalization module 52 is respectively connected to the sensing assembly 2 and the control module 51, so as to process the collected data and forward the processed data to the control module 51 for display and adaptive adjustment. On this basis, the connection of the processing apparatus 300 and the pulse data detection apparatus 200 may be established through a connection with the control module 51, and the control module 51 and the processing apparatus 300 may be configured as a communication connection. Correspondingly, there may be an electrical or communication connection between the sensing device 2 and the standardized module 52, between the standardized module 52 and the control module 51, and between the control module 51 and the sensing device 2 for data transmission, and a communication connection may be used between the processing device 300 and the sensing device 2 and the control module 51, respectively.
In the present embodiment, the relative positional relationship between the time sensor 21 and the space sensor 22 may be such that they are arranged one on top of the other in a direction perpendicular to the region to be measured 10 to form a mutual correspondence relationship between the first pressure-receiving data group and the second pressure-receiving data group. In the above relative positional relationship, it is more preferable that the time sensor 21 is disposed close to the space sensor 22 and on the side of the space sensor 22 close to the region to be measured. In this way, the time sensor 21 can be given a higher detection sensitivity, the fluctuation range due to the entire detection is balanced to be small, and the space sensor 22 can be given a wider detection range, and more data for analysis can be acquired with a limited component volume configuration. As can be seen from the arrangement of the air bag 42 in the foregoing embodiment, in a preferred embodiment, the space sensor 22 may be arranged to be sandwiched between the air bag 42 and the time sensor 21, thereby achieving all the above-mentioned advantageous effects and improving the degree of integration of the apparatus.
As shown in fig. 2, 3, 5 and 6, the space sensor 21 may specifically include a plurality of space sensing portions 221 arranged in a matrix, where the space sensing portions 221 are preferably configured to be disposed close to the region to be measured 10 and used for detecting and obtaining the second pressure data set. Based on the method, the matrix arrangement mode not only can be convenient for determining the position data set and establishing the mapping relation, but also is convenient for detecting more second pressure data sets in a small range to analyze. Preferably, when the coverage range of the data in the second pressure data set is expanded, data errors and fluctuations may be accompanied, so that the accuracy of the subsequent pulse condition classification or pulse feature analysis may be improved by adjusting the density degree and the overall position of the matrix arrangement, for example, arranging a denser space sensing part 221 in the middle and a sparser space sensing part 221 around, and further configuring the plurality of space sensing parts 221 to have a pressure data dispersion smaller than 10%.
More specifically, corresponding to the ruler regions 10A and 10b, respectivelyThe spacing between the centers of the two sensing elements 2 of the close region 10B may be configured to be equal to the spacing between the centers of the two sensing elements 2 corresponding to the close region 10B and the inch region 10C, respectively, and in a specific example, the spacing may be 11.5 mm. The plurality of space sensing parts 221 on the space sensor 22 may be configured to present a 5 × 4 matrix along the second direction W2 and the first direction W1, respectively, that is, a total of 20 space sensing parts 221 are configured. In addition, the area of the time sensing part 211 corresponding to the time sensor 21 and the space sensor 22 may be set to be larger than that of the time sensor 21
Or (10X 10) mm 2 The full-scale working range can be 0-300mmHg, and the sensitivity can be 1 mmHg; the whole area of the space sensor 221 corresponding to the latter may be (10 × 10) mm 2 The full scale operating range may be 0-250mmHg and the sensitivity may be 1 mmHg.
In summary, the pulse data detection device provided by the invention is provided with the time sensor and the space sensor, and the overlapping part of the detection ranges of the time sensor and the space sensor at least covers the area to be detected, so that the pulse data on the area to be detected is completely detected from two dimensions of time and space, and the data of the pulse data changing along with time is superposed to form a contrast reference on the basis of keeping the pulse data detection on different positions, so that medical personnel can judge the pulse condition more comprehensively, and the accuracy and precision of pulse condition identification are improved.
