Description
Technical Field
The application relates to the field of communication, in particular to a technology for measuring pulse information of a user by using pulse feeling equipment.
Background
The pulse is an artery pulse which can be touched on the surface of a human body. The blood is squeezed into the aorta by the contraction of the left ventricle of the heart and then delivered to the systemic arteries. The artery is a conduit formed by connective tissues and muscles with high elasticity. When a large amount of blood enters the artery, the pressure of the artery increases and the caliber expands, so that the artery feels the expansion at a shallow body surface, namely the pulse.
Pulse diagnosis is a palpation method to examine the changes of pulse conditions by touching the pulse at different parts of the body. The traditional pulse feeling is realized by the sensitive touch of the fingers of the doctor. The existing pulse feeling equipment mainly collects pulse signal information of a human body through a sensor and analyzes and processes the pulse signal information so as to achieve the purpose of pulse feeling.

Fig. 3 shows a flowchart of a method for measuring pulse information of a user using a pulse feeling device according to an embodiment of the present application, the method including step S11, step S12, step S13 and step S14. In step S11, the pulse taking device acquires first pulse information of a first user through the pressure sensor matrix, wherein the forearm of the first user is placed in the cavity and the second measurement unit covers the wrist area of the first user, the pressure sensor matrix comprises a plurality of pressure sensors; in step S12, the pulse taking device determines one or more target pressure sensors in the pressure sensor matrix adjacent to the first pulse point generating the first pulse information; in step S13, the pulse feeling apparatus determines driving instruction information corresponding to the first measurement unit according to the position information of the target pressure sensor in the pressure sensor matrix and the current position information of the second measurement unit and the first measurement unit, wherein the driving instruction information is used for driving the first measurement unit to move so that the single-point pressure sensor is aligned with the first pulse point; in step S14, the pulse feeling device drives the first measuring unit to move along the first track according to the driving instruction information when the second measuring unit leaves the wrist area of the first user so that the single-point pressure sensor is aligned with the first pulse point, and measures second pulse information of the first user by using the single-point pressure sensor.
In step S11, the pulse taking device acquires first pulse information of a first user through the pressure sensor matrix, wherein the forearm of the first user is placed in the cavity and the second measurement unit covers the wrist area of the first user, and the pressure sensor matrix comprises a plurality of pressure sensors. For example, when a first user's wrist is placed within the body of the pulse taking device, the second measurement unit covers the first user's wrist area, i.e., the initial position of the second measurement unit is set at a position that can cover the user's wrist area. The initial position of the second measuring unit may be determined according to the prevailing position of the user's wrist when placed in the cavity. In some embodiments, the plurality of pressure sensors included in the pressure sensor matrix can respectively collect pulse information of the positions of the pressure sensors. The first pulse information comprises one or more pulse information which is output by the pressure sensor matrix and is matched with the pulse waveform. The pulse information is acquired, that is, the distance between the pressure sensor for acquiring the pulse information and the wrist pulse point of the user is very close, and the acquisition point position corresponding to the pressure sensor for acquiring the pulse information can be regarded as the wrist pulse point position of the user.
In step S12, the pulse feeling device determines one or more target pressure sensors in the pressure sensor matrix adjacent to the first pulse point generating the first pulse information. For example, a plurality of pressure sensors are located in the area where the wrist pulse point of the user is located, and the pressure sensors can acquire pulse signals generated by the wrist pulse point of the user. The pulse feeling device determines the pressure sensor which acquires the pulse information generated by the pulse point of the wrist of the user in the pressure sensor matrix as a target pressure sensor.
In step S13, the pulse feeling apparatus determines driving instruction information corresponding to the first measurement unit according to the position information of the target pressure sensor in the pressure sensor matrix and the current position information of the second measurement unit and the first measurement unit, wherein the driving instruction information is used for driving the first measurement unit to move so that the single-point pressure sensor is aligned with the first pulse point. For example, the pulse feeling device may consider the position information of the target pressure sensor in the pressure sensor matrix as the position information of the first pulse point corresponding to the pressure sensor matrix. The pulse feeling equipment determines target displacement required by the first measuring unit to move to the first pulse point according to the position information and the current position information of the second measuring unit and the first measuring unit, and determines corresponding driving instruction information according to the target displacement.
In step S14, the pulse feeling device drives the first measuring unit to move along the first track according to the driving instruction information when the second measuring unit leaves the wrist area of the first user so that the single-point pressure sensor is aligned with the first pulse point, and measures second pulse information of the first user by using the single-point pressure sensor. In some embodiments, to avoid collision of the first measurement unit with the second measurement unit, the pulse taking device may first actuate the second measurement unit away from the wrist area of the first user to ensure safe movement of the first measurement unit. The pulse feeling equipment can drive the second measuring unit to move to the designated safe position information according to the preset movement information. In some embodiments, the first measurement unit and the second measurement unit may be respectively connected to a first driving unit (e.g., a driving motor) and a second driving unit, and the pulse feeling device may control the second driving unit to drive the second measurement unit to leave the wrist area of the first user, and then control the first driving unit to drive the first measurement unit to move along a first track according to the driving instruction information, so that the single-point pressure sensor is aligned with the first pulse point.
In some embodiments, the method further comprises, before step S14: step S15 (not shown), if a trigger condition for driving the second measuring unit is satisfied, the pulse taking device drives the second measuring unit to move the second measuring unit away from the wrist area of the first user. For example, if the second measurement unit completes the pulse information acquisition of the wrist area of the first user, or determines the driving instruction information, the first measurement unit can be driven to align with the wrist pulse point of the user at any time; the trigger condition for driving the second measuring unit can be considered to be satisfied, and the pulse feeling device drives the second measuring unit away from the wrist area of the first user.
In some embodiments, the second measurement unit may be coupled to a second drive unit (e.g., a drive motor), and the pulse taking device may control the second drive unit to drive the second measurement unit away from the wrist area of the first user. In some embodiments, the pulse feeling device determines the movement information corresponding to driving the second measuring unit away from the first user wrist area according to the designated safe position information corresponding to the second measuring unit. When the second measuring unit is located at the position corresponding to the designated safe position information, the moving safety of the first measuring unit can be ensured. The movement information may be determined based on the designated safe location information and the location information of the second measurement unit. For example, if the second measurement unit covers the wrist area of the first user when being at the initial position, the movement information is determined according to the distance between the initial position and the position corresponding to the designated safe position information. And if the second measuring unit generates excessive displacement in the process of covering the first user wrist area, determining the movement information according to the displacement information and the distance between the initial position and the position corresponding to the designated safety position information.
In some embodiments, the trigger condition comprises at least any one of: the pulse feeling apparatus has determined the drive instruction information; the pulse taking apparatus has determined one or more target pressure sensors adjacent to the first pulse point that generated the first pulse information; the pulse feeling device has acquired the first pulse information through the pressure sensor matrix. For example, when the second measurement unit leaves the wrist area of the first user without affecting the subsequent work of the pulse diagnosis device, or the second measurement unit has completed pulse information acquisition or determined driving instruction information, and needs to drive the first measurement unit to move, it can be considered that the trigger condition is satisfied, and the pulse diagnosis device needs to drive the second measurement unit to leave the wrist area of the user, so as to drive the first measurement unit subsequently.
In some embodiments, the step S12 includes: the pulse feeling equipment acquires output signals of all pressure sensors in the pressure sensor matrix and detects whether the output signals of the pressure sensors are matched with pulse waveforms; determining one or more target pressure sensors adjacent to the first pulse point generating the first pulse information from a plurality of pressure sensors in the pressure sensor matrix, wherein an output signal of each target pressure sensor matches a pulse waveform.
In some embodiments, the matching of the output signal of the pressure sensor to the pulse waveform includes, but is not limited to: the output signal of the pressure sensor comprises pulse wave characteristic points (such as an aortic valve opening point, a systolic highest pressure point, an aortic dilation depressurization point, a left ventricular diastole starting point, a tidal wave return highest pressure point and the like), the cycle time of the output signal of the pressure sensor is in a pulse wave cycle interval, or the wavelet entropy value corresponding to the output signal of the pressure sensor is in a wavelet entropy value interval corresponding to the pulse wave. In some embodiments, said determining one or more target pressure sensors adjacent to said first pulse point generating said first pulse information comprises determining one or more pressure sensors whose output signals most closely match a pulse waveform. The highest matching degree comprises the most matching items of the output signals and the pulse waveforms.
Here, it should be understood by those skilled in the art that the method of matching the output signal of the pressure sensor to the pulse waveform is merely an example. Other existing or later-developed methods for determining whether the output signal of the pressure sensor matches the pulse waveform may be used with this embodiment, and are included within the scope of this embodiment and are hereby incorporated by reference.
In some embodiments, the step S13 includes: step S131 (not shown), determining, by the pulse feeling equipment, a target displacement corresponding to the first measurement unit according to the position information of the target pressure sensor in the pressure sensor matrix and the current position information of the second measurement unit and the first measurement unit, wherein the single-point pressure sensor is aligned with the first pulse point after the first measurement unit passes through the target displacement; step S132 (not shown), the pulse feeling device generates driving instruction information corresponding to the first measurement unit according to the target displacement, where the driving instruction information is used to drive the first measurement unit to move so that the single-point pressure sensor aligns with the first pulse point.
In some embodiments, if the second measuring unit covers the wrist area of the first user when the second measuring unit is at the initial position, the current position information of the second measuring unit and the first measuring unit may be determined according to the initial position information between the initial positions respectively corresponding to the second measuring unit and the first measuring unit. Otherwise, the pulse feeling equipment determines the current position information of the second measuring unit and the first measuring unit according to the displacement information generated by the measuring unit in the process of covering the wrist area of the first user and the initial position information between the initial positions respectively corresponding to the second measuring unit and the first measuring unit. The position information of the target pressure sensor in the pressure sensor matrix can be determined according to the position information of the target pressure sensor relative to the center of the pressure sensor matrix. In some embodiments, the driving instruction information includes the target displacement, and the pulse feeling apparatus can drive the first measurement unit to generate a corresponding movement according to the target displacement in the driving instruction information so as to align the single-point pressure sensor with the first pulse point.
In some embodiments, the step S131 includes: step S1311 (not shown), the pulse feeling apparatus determines the position information of the first pulse point according to the position information of the target pressure sensor in the pressure sensor matrix; step S1312 (not shown), determining, by the pulse feeling apparatus, a target displacement corresponding to the first measurement unit according to the position information of the first pulse point and the current position information of the second measurement unit and the first measurement unit, wherein the single-point pressure sensor is aligned with the first pulse point after the first measurement unit passes through the target displacement. In some embodiments, said determining location information for said first pulse point from location information for said target pressure sensor in said pressure sensor matrix comprises: determining regional location information of one or more target pressure sensors in the pressure sensor matrix according to one or more location information of the one or more target pressure sensors in the pressure sensor matrix, determining the regional location information as location information of the first pulse point, wherein the regional location information comprises the one or more location information; or determining central position information corresponding to the area position information as the position information of the first pulse point. The determined position information of the first pulse point is the position information of the position of the first pulse point corresponding to the pressure sensor matrix. And the pulse feeling equipment determines the target displacement corresponding to the first measuring unit according to the position information of the first pulse point and the current position information of the second measuring unit and the first measuring unit.
In some embodiments, the step S1312 includes: the pulse feeling equipment determines a target position corresponding to the first measuring unit according to the position information of the first pulse point and the current position information of the second measuring unit, wherein the single-point pressure sensor is aligned to the first pulse point when the first measuring unit is at the target position; and determining a target displacement corresponding to the first measuring unit according to the target position corresponding to the first measuring unit and the current position information of the first measuring unit, wherein the single-point pressure sensor is aligned to the first pulse point after the first measuring unit passes through the target displacement. For example, the pulse feeling device determines the position information of the first pulse point in the pulse feeling device according to the position information of the first pulse point and the current position information of the second measurement unit, wherein the current position information of the second measurement unit is the current position information of the second measurement unit in the pulse feeling device. The target position corresponding to the first measurement unit comprises the position information of the first pulse point in the pulse diagnosis device, namely the position information of the first pulse point relative to the second measurement unit is converted into the position information relative to the pulse diagnosis device according to the current position information of the second measurement unit. Here, since the target position corresponding to the first measurement unit and the current position information of the first measurement unit are under the same reference, the target displacement corresponding to the first measurement unit can be directly determined from both.
In some embodiments, the first measuring unit is mounted to the first rail through a second rail, the second rail is mounted to the first rail in the width direction of the wrist band and is movable in the length direction of the wrist band along the first rail, and the first measuring unit is movable in the width direction of the wrist band along the second rail. For example, referring to a schematic diagram of the inner side structure of the wrist band of the pulse diagnosis apparatus shown in fig. 2, the inner side of the wrist band is mounted with a second rail 106 along the width direction of the wrist band, the second rail 106 is mounted on the first rail 103, and the first measurement unit 104 is mounted on the second rail 106. In one aspect, the second track 106 is movable with the first measuring unit 104 along the first track 103 in a wrist band length direction; on the other hand, the first measurement unit 104 is movable along the second rail 106 in the wristband width direction. Through the two tracks, the first measuring unit can be moved to any position on the inner side of the wrist strap, so that the single-point pressure sensor is aligned with the pulse point of the wrist of the user. Here, the moving direction of the first measuring unit is not limited to one another. The first measuring unit can move along the first track and then move along the second track; or the device can move along the second track firstly and then move along the first track; or both, along the first and second tracks (e.g., the first measurement unit moves along the second track while the second track carries the first measurement unit along the first track).
In some embodiments, the step S14 includes: when the second measuring unit leaves the wrist area of the first user, the pulse feeling device drives the first measuring unit to move along the first rail and then along the second rail according to the driving instruction information, so that the single-point pressure sensor is aligned with the first pulse point, and the single-point pressure sensor is used for measuring second pulse information of the first user. For example, the first measuring unit is connected with a first driving unit through a second rail, and the pulse feeling device can drive the first measuring unit to move along the first rail along with the second rail through the first driving unit. The first measuring unit is further connected with a third driving unit, and the pulse feeling equipment can drive the first measuring unit to move along the second track through the third driving unit. When the second measuring unit leaves the wrist area of the first user, the pulse feeling device can drive the first measuring unit to move along the first track along with the second track through the first driving unit, and then drive the first measuring unit to move along the second track through the third driving unit, so that the single-point pressure sensor is aligned with the first pulse point.
In some embodiments, the outside of the wristband is covered with an air bag, and the S14 includes: when the second measuring unit leaves the wrist area of the first user, the pulse feeling device drives the first measuring unit to move along the first rail according to the driving instruction information so that the single-point pressure sensor is aligned with the first pulse point, performs an inflation operation on the air bag so that the single-point pressure sensor is attached to the first pulse point, and measures second pulse information of the first user by using the single-point pressure sensor. For example, when the first measurement unit moves to a corresponding position according to the driving instruction information, the single-point pressure sensor is aligned with the first pulse point, but at this time, a gap may exist between the single-point pressure sensor and the first pulse point, and the wrist position of the user may move, so that the single-point pressure sensor cannot accurately measure the second pulse information. The pulse feeling equipment can make the pulse measuring position fixed by inflating and pressurizing the air bag covered on the outer side of the wrist strap to make the single-point pressure sensor close to the first pulse point. The inflation operation includes: the pulse feeling equipment inflates and pressurizes the air bag according to the initial air bag pressurization parameter; detecting whether the single-point pressure sensor acquires second pulse information of the first user; if so, the single-point pressure sensor can be considered to be tightly attached to the first pulse point, the inflation operation can be stopped, and second pulse information of the first user is measured; otherwise, adjusting the current air bag pressurization parameter, and inflating and pressurizing the air bag according to the adjusted current air bag pressurization parameter until the single-point pressure sensor is tightly attached to the first pulse point. Still alternatively, the pulse feeling device may determine an airbag pressurization parameter matching the wrist of the first user according to the wrist-related data (e.g., the width, height, etc. of the wrist) of the first user, and inflate and pressurize the airbag according to the airbag pressurization parameter to make the single-point pressure sensor close to the first pulse point.
It will be understood by those skilled in the art that the above-described inflation operation is by way of example only. Other existing or later-developed methods for inflating the bladder to bring the single-point pressure sensor into close proximity with the pulse point of the wrist of the user may be suitable for use with this embodiment, and are also included within the scope of this embodiment and are hereby incorporated by reference.
In some embodiments, the step S11 includes: when the forearm of the first user is placed in the cavity and the second measuring unit covers the wrist area of the first user, the pulse feeling device performs inflation operation on the air bag to enable the pressure sensor matrix to be close to the wrist area of the first user, and acquires first pulse information of the first user through the pressure sensor matrix, wherein the pressure sensor matrix comprises a plurality of pressure sensors; the method further comprises, before the step S14, a step S16 (not shown): performing a deflation operation on the bladder to disengage the matrix of pressure sensors from the wrist area of the first user. For example, the pulse taking device also requires pressurizing the bladder by inflating the pressure sensor matrix against the user's wrist. The operation of inflating the pressure sensor matrix against the wrist of the first user by the pulse feeling device is the same as or similar to the operation of inflating the single-point pressure sensor against the first pulse point in step S14, and therefore, the detailed description thereof is omitted and is included herein by reference. At the moment, gas exists in the air bag, the pressure sensor matrix is close to the wrist of the user and is inconvenient to move, so that the air bag needs to be deflated before the second measuring unit moves, the pressure sensor matrix is separated from the first user wrist area, and the subsequent movement of the second measuring unit and the first measuring unit is facilitated.
