Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a measurement method, device, cardiopulmonary resuscitation device, storage medium, and computer program product for cardiopulmonary resuscitation. Background Technology

[0002] The heart, as the most vital organ, is normally located in the lower left part of the chest cavity, enclosed by the rib cage formed by the sternum. However, injuries caused by various reasons can cause the heart to stop beating, a condition medically known as cardiac arrest. Currently, the primary treatment for cardiac arrest patients is cardiopulmonary resuscitation (CPR), which involves external chest compressions to provide the heart, brain, and other vital organs with a minimum level of emergency oxygen, offering the most basic life support.

[0003] When performing CPR, insufficient chest compressions or using only abdominal thrusts may have limited effectiveness, failing to achieve the desired CPR outcome. Conversely, excessive chest compressions or force may cause sternal collapse or even fracture, with the fractured bone fragments potentially causing further injury. Therefore, the depth and force of chest compressions during CPR must be appropriate.

[0004] Cardiopulmonary resuscitation (CPR) is generally divided into manual CPR and CPR using equipment. When using equipment for CPR, the compression depth can be too large or the force can be easily controlled. However, currently, during manual CPR, rescuers often rely solely on their senses to perform continuous chest compressions. Because the benefits of restoring spontaneous circulation through CPR far outweigh the risks of fractures, the risks of sternal collapse and fractures must often be ignored during manual CPR.

[0005] Therefore, how to control the compression pressure during cardiopulmonary resuscitation to avoid risks such as sternal collapse and fracture is one of the technical problems that urgently need to be solved. Summary of the Invention

[0006] Therefore, it is necessary to provide a measurement method, device, cardiopulmonary resuscitation device, storage medium, and computer program product for cardiopulmonary resuscitation to address the aforementioned technical problems.

[0007] In a first aspect, this application provides a measurement method for cardiopulmonary resuscitation, the method comprising:

[0008] First sensors are respectively installed at multiple preset positions on the outside of the user's sternum; each first sensor includes at least a bending component, the bending component includes an inner wire, and a sheath made of a spiral coil is wrapped around the outside of the inner wire; wherein the preset positions include at least the two sides of the center of the sternum.

[0009] The displacement of the corresponding inner wire of the sheath under pressure is collected by multiple first sensors respectively;

[0010] Based on the coil diameter, total number of coils, and width of each sheath, as well as the displacement of the inner wire corresponding to the sheath, the bending angle of the inner wire corresponding to each sheath is obtained.

[0011] The second sensor is used to obtain depth change data at the pressing position;

[0012] Based on all the bending angles and depth variation data of the inner lines, the measured sternal contour shape of the user during compression is calculated.

[0013] The measured sternal contour shape is compared with the first preset sternal contour shape. If the measured contour shape is below the first preset sternal contour shape, it is determined to be a first compression abnormality, and a first compression abnormality prompt message is output.

[0014] In one possible implementation, comparing the measured sternal contour shape with a first preset sternal contour shape further includes:

[0015] If the measured contour shape intersects with the first preset sternal contour shape, it is determined to be a second compression abnormality, and a second compression abnormality prompt message is output; the second compression abnormality prompt message is different from the first compression abnormality prompt message.

[0016] In one possible implementation, before or after comparing the measured sternal contour shape with a first preset sternal contour shape, the method further includes:

[0027] In one possible implementation, the first preset sternal contour shape is obtained by means of:

[0028] Based on the curvature angle threshold dataset, the first preset sternal contour shape is obtained;

[0029] Alternatively, the first preset sternal contour shape can be obtained by calibrating the user's physical indicators and effective compression data from historical cardiopulmonary resuscitation.

[0030] In one possible implementation, the second preset sternal contour shape is obtained based on the user's physical indicators and calibrated from historical data on ineffective CPR compressions.

[0031] Secondly, this application also provides a cardiopulmonary resuscitation data processing device, the device comprising:

[0040] In one possible implementation, the first analysis and judgment unit is further configured to determine a second compression abnormality if the measured contour shape intersects with the first preset sternal contour shape.

[0041] The information output unit is configured to output a second press abnormality prompt message, which is different from the first press abnormality prompt message.

[0042] In one possible implementation, the first analysis and judgment unit is further configured to determine a third compression abnormality if the measured contour shape is located above the second preset sternal contour shape.

[0043] The information output unit is configured to output a third abnormal pressing prompt message indicating increased force.

[0044] In one possible implementation, the first analysis and judgment unit is configured to compare the measured sternal contour shape with a second preset sternal contour shape, and if the measured contour shape is below the second preset sternal contour shape, and to compare the measured sternal contour shape with a first preset sternal contour shape, and if the measured contour shape is above the first preset sternal contour shape, then the compression is determined to be normal.

[0045] In one possible implementation, the first processing unit is further configured to obtain a bending angle threshold of the sternum corresponding to each of the preset positions;

[0046] The first analysis and judgment unit is further configured to determine whether the bending angle of the inner line corresponding to each preset position meets the safety requirements based on the bending angle threshold of the sternum corresponding to each preset position.

[0047] If the sternal bending angle threshold corresponding to at least one of the preset positions is less than the bending angle of the corresponding inner line, then a fourth abnormal pressing prompt message is sent.

[0048] The information output unit is also configured to output the fourth abnormal press prompt information.

[0049] In one possible implementation, the step of obtaining the sternal curvature angle threshold corresponding to each of the preset positions includes:

[0050] Obtain the user's body indicator information, wherein the body indicator information includes one or more of the following: height, weight, body fat percentage, gender, chest size, and clothing size;

[0051] Determine a dataset of curvature angle thresholds that match the body metric information;

[0052] Obtain the bending angle threshold corresponding to each of the preset positions from the bending angle threshold dataset.

[0053] In one possible implementation, the first preset sternal contour shape is obtained by means of:

[0054] Based on the curvature angle threshold dataset, the first preset sternal contour shape is obtained;

[0055] Alternatively, the first preset sternal contour shape can be obtained by calibrating the user's physical indicators and effective compression data from historical cardiopulmonary resuscitation.

[0056] In one possible implementation, the second preset sternal contour shape is obtained based on the user's physical indicators and calibrated from historical data on ineffective CPR compressions.

[0057] Thirdly, this application also provides a cardiopulmonary resuscitation device, including a body, in which a cardiopulmonary resuscitation measuring device as described in any one of the embodiments of this disclosure is arranged; when the body is placed on the user, the first sensor is provided at least on both sides of the center of the user's sternum at corresponding positions.

[0058] In one possible implementation, the body is a wearable defibrillator or a chest strap.

[0059] Fourthly, this application also provides an electronic device, including a memory and a processor, wherein:

[0060] The processor is used to execute computer programs stored in the memory;

[0061] When the processor executes the computer program, it implements the steps in the measurement method for cardiopulmonary resuscitation as described in any one of the embodiments of this disclosure.

[0062] Fifthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, implements the steps of the measurement method for cardiopulmonary resuscitation as described in any one of the embodiments of this disclosure.

[0063] In the above-described embodiment of the cardiopulmonary resuscitation measurement method, the displacement of the corresponding inner line is acquired through first sensors at multiple preset positions. Based on the coil diameter, total number of coils, and width of the sheath of the first sensor's bending component, and the displacement of the inner line corresponding to the sheath, the bending angle of the inner line corresponding to each sheath is obtained. Combined with the depth change data of the compression position, the user's measured sternal contour shape is determined. Compared to traditional methods using flexible sensors, the bending angle and the change in inner line displacement determined by this embodiment have better linearity and resolution. The linearity refers to a certain linear relationship between the change in inner line displacement and the bending angle. Therefore, this embodiment can more accurately determine the user's measured sternal contour shape. When the measured contour shape is below the first preset sternal contour shape, a first compression anomaly warning message is output. This embodiment, through the anomaly warning message, can adjust the compression force in a timely manner, thereby reducing the risk of sternal collapse or fracture. Attached Figure Description

[0076] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0077] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0078] The measurement method for cardiopulmonary resuscitation provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, the acquisition module 103 may include multiple first sensors positioned at multiple preset locations on the outside of the user's sternum. Each first sensor includes at least a bending component, which comprises an inner wire wrapped with a sheath consisting of a spiral coil. The first sensor is used to acquire the displacement of the inner wire corresponding to the pressure applied to the sheath. The acquisition module 103 may also include a second sensor, which acquires depth change data at the pressure position. The microcontroller unit 101 (MCU) can process the acquired data; in another exemplary embodiment, the microcontroller unit can also send the acquired data to the processing module 109 to instruct the processing module 109 to process the acquired data. Through processing, the bending angle of the inner wire of the first sensor at the preset position can be obtained. If the bending angle is greater than a bending angle threshold, an abnormal warning message is sent through the warning module 105. The microcontroller unit 101 can communicate with the host computer 107, for example, receiving the bending angle threshold sent by the host computer 107, and sending the user's measured sternal contour shape to the host computer 107, so as to display the measured sternal contour shape on the host computer 107.

[0079] In one embodiment, such as Figure 2 As shown, a measurement method for cardiopulmonary resuscitation is provided, including the following steps:

[0080] Step S201: First sensors are respectively installed at multiple preset positions on the outside of the user's sternum; each first sensor includes at least a bending component, the bending component includes an inner wire, and a sheath made of a spiral coil is wrapped around the outside of the inner wire; wherein the preset positions include at least the two sides of the center of the sternum.

[0081] Specifically, the first sensor can be positioned at multiple preset locations on the outer side of the user's sternum. These preset locations can be located on the same plane or on different planes. The planes are not actual physical planes; their function is to characterize the distribution of the preset locations. In an exemplary embodiment, refer to... Figure 3 As shown in the figure, a, b, c, d, m, and n each correspond to a preset position, and all preset positions are located on the same cross-section. The preset positions at least include both sides of the center of the sternum, for example... Figure 3 Points m and n in the equation. Optionally, the preset positions include: the region where the sternum indents when pressed and / or the region where the shape of the sternum changes. Specifically, the region where the sternum indents when pressed is, for example, Figure 3 In the process, when the preset position e is pressed, points m and n will be indented, so m and n can be used as preset positions. This is used to set the sensor. In an exemplary embodiment, refer to... Figure 3 As shown, points a, b, c, and e are the bends of the sternum, and these points can be used as preset positions for setting the sensor. The locations where indentation occurs during pressure and the bends of the sternum show significant displacement changes during pressure, clearly reflecting changes in the shape of the sternum contour. Therefore, using these locations as preset positions, compared to selecting other locations, helps to accurately determine the shape of the sternum contour, thereby reducing the number of preset positions, i.e., reducing the number of first sensors installed. It should be noted that the embodiments of this disclosure are not limited to the locations where indentation occurs when the sternum is pressed, or the bends in the sternum shape; areas within a preset range near these locations should also be considered as preset positions. Those skilled in the art may make other modifications based on the essence of this application, but as long as the achieved function and effect are the same as or similar to this application, they should be covered within the scope of protection of this application. In the embodiments of this disclosure, the first sensor includes at least a bending component, the bending component including an inner wire, and a sheath composed of a threaded coil wrapped around the outer side of the inner wire. In an exemplary embodiment, refer to... Figure 4 As shown, the first sensor includes a bending component 401 and a sensing component 403, wherein the bending component 401 is bendable. Optionally, the first sensing component 403 is a Hall sensor, which is more sensitive to changes in the inner line displacement of the bending component 401, thereby detecting the displacement of the inner line more accurately. In an exemplary embodiment, referring to... Figure 5 As shown, the first sensor can be an existing Bowden sensor. This disclosure does not limit the type of the first sensor.

[0082] Step S203: Use multiple first sensors to collect the displacement of the corresponding inner wire of the sheath when it is under pressure.

[0083] In this embodiment, the displacement of the inner wire can include the difference between the length of the inner wire when the bending component is not bent and the length of the inner wire when it is bent. The compression of the sheath includes the compression of the sheath caused by changes in the user's sternum during cardiopulmonary resuscitation. In this embodiment, the number of displacement measurements collected is matched to the number of the first sensors.

[0084] Step S203: Based on the coil diameter of each sheath, the total number of coils and the width of the coil, and the displacement of the inner wire corresponding to the sheath, obtain the bending angle of the inner wire corresponding to each sheath.

[0085] For details, please refer to Figure 6As shown, the coil 601 of the sheath of the first sensor is rectangular. The coil diameter of the sheath refers to the circumference diameter of the coil around the inner wire. For example, in the figure, d represents the coil diameter of the sheath, b represents the width of the coil, and n represents the total number of coils, for example, the total number of coils 601 in the figure. In this embodiment of the disclosure, the inner wire of the bent component is simulated by a wire 603 passing through the center of the coil. The included angle between the threads of the two coils is represented by α1, α2, and α3 in the figure, and the arc lengths of the sector containing the included angle are x1, x2, and x3, respectively, which are called the increase in center displacement. Reference Figure 7 As shown, when the aforementioned included angle α i When it is small, the corresponding arc length x i The size is approximately equal to the base of an isosceles triangle with the aforementioned included angle as its vertex and half the diameter of the coil as its legs. Therefore, the arc length x... r The calculation formulas include:

[0086]

[0087] Where i = 1, 2, 3…, when the included angle α i When α is small, each i If their sizes are approximately equal, then

[0088]

[0089] in,

[0090]

[0091]

[0092] The displacement change Δl of the line passing through the center of the coil is the sum of the increases in the center displacement:

[0093]

[0094] In this embodiment, the collected data, namely the change in linear displacement Δl within the first sensor, can be directly measured by the first sensor, and the bending angle can be derived by reversing the formula (5). Bending angle The expression is as shown in equation (6), with reference to each bending angle. Figure 3 θ1, θ2, θ3, θ4, θ5 in .

[0095]

[0096] Step S205: Use the second sensor to obtain depth change data of the pressing position.

[0097] The second sensor can be positioned at the compression point on the sternum. In a cardiopulmonary resuscitation (CPR) scenario, the compression point can include the area between the nipples or other designated locations. The second sensor can also acquire data using a chest compression meter. In an exemplary embodiment, refer to... Figure 3 As shown, the depth change data collected by the second sensor can include the depth change data h at the pressing position e.

[0098] Step S207: Based on all the bending angles of the inner lines and the depth change data, the measured sternal contour shape of the user during pressure is calculated.

[0099] Specifically, the change in inner line displacement is represented by the change in the length of the bending component of the first sensor at each preset position. The bending angle represents the magnitude of the bending angle corresponding to the bending component. Since the preset positions of each first sensor are known, the position of the first sensor, the change in the length of the bending component, and the change in angle can be simulated and displayed. By connecting the bending component data corresponding to adjacent first sensors, a partial contour of the user's sternum can be obtained. Optionally, by combining the depth change data at the compression position, the depth change at the compression position can be obtained. This depth change can then be combined with the partial contour obtained above to obtain the measured shape of the user's sternum.

[0100] In one exemplary embodiment, the first sensor 801 may be pre-set on the cardiopulmonary resuscitation device 800, with reference to Figure 8 As shown, the corresponding cardiopulmonary resuscitation (CPR) devices may differ depending on age and gender. In an exemplary embodiment, the distance data between the first sensors of the CPR device can be determined based on the model of the user's current CPR device. With breathing or external compression, the sternal contour changes, manifested as changes in various bending angles. The change in inner line displacement in the collected data is used to determine the user's sternal contour shape based on the aforementioned bending angle and depth change data. It should be noted that... Figure 8 The cardiopulmonary resuscitation device described is merely an example, and this disclosure does not limit the type of cardiopulmonary resuscitation device.

[0101] Step S211: Compare the measured sternal contour shape with the first preset sternal contour shape. If the measured contour shape is below the first preset sternal contour shape, it is determined to be a first pressing abnormality, and a first pressing abnormality prompt message is output.

[0102] In this embodiment of the disclosure, the first preset sternal contour shape serves as a first reference. When the measured sternal contour shape is located below the first preset sternal contour shape—for example, when a certain number of points or line segments on the measured sternal contour shape are below the first preset sternal contour shape—it is determined to be a first compression anomaly, and a first compression anomaly prompt message is output. In this embodiment of the disclosure, the area below the shape of the first preset sternal contour includes the area in front of the compression direction, for example… Figure 3 In this embodiment, the back contour shape is located below the abdominal contour shape. The first abnormal pressure warning message is used to alert the user that the sternum may collapse or fracture. It should be noted that when the measured sternum contour shape in this embodiment is located below the first preset sternum contour shape, it cannot directly diagnose whether the user has suffered a fracture, but it indicates a potential risk of fracture.

[0103] In the embodiment of the above-described cardiopulmonary resuscitation measurement method, the displacement of the corresponding inner line is obtained through first sensors at multiple preset positions. Based on the coil diameter, total number of coils, and width of the sheath of the first sensor's bending component, and the displacement of the inner line corresponding to the sheath, the bending angle of the inner line corresponding to each sheath is obtained. Combined with the depth change data of the compression position, the user's measured sternal contour shape is determined. Compared to traditional flexible sensors, the bending angle and the change in inner line displacement determined by this embodiment have better linearity and resolution. The linearity refers to a certain linear relationship between the change in inner line displacement and the bending angle. Therefore, this embodiment can more accurately determine the user's measured sternal contour shape. When the measured contour shape is below the first preset sternal contour shape, a first compression anomaly warning message is output to indicate to the user that the sternum may collapse or fracture.

[0104] In one possible implementation, the step of comparing the measured sternal contour shape with a first preset sternal contour shape further includes:

[0105] If the measured contour shape intersects with the first preset sternal contour shape, it is determined to be a second compression abnormality, and a second compression abnormality prompt message is output; the second compression abnormality prompt message is different from the first compression abnormality prompt message.

[0106] In this embodiment, the intersection of the measured contour shape and the first preset sternal contour shape may include a greater than a preset proportion of overlap, for example, more than 70% overlap. When the measured contour shape intersects with the first preset sternal contour shape, a second abnormal compression warning message is output. This second abnormal compression warning message prompts the user to reduce the compression intensity, otherwise the user's sternum may collapse or fracture. The likelihood of a sternal fracture is lower when the second abnormal compression warning message is output compared to when the first abnormal compression warning message is output. In an exemplary embodiment, the first and second abnormal compression warning messages can employ different alerting methods; for example, the former may use sound and vibration, while the latter uses only sound, to emphasize the urgency of the situation. Optionally, the difference can also be reflected through different text content in the voice messages; for example, the first abnormal compression warning message may include "Excessive force may cause a fracture," while the second abnormal compression warning message may include "Excessive force may cause a fracture." In another exemplary embodiment, the two types of prompting information can also be distinguished by prompting devices of different styles or colors. For example, a red warning light corresponds to a first abnormal pressing prompting information, and a yellow warning light corresponds to a second abnormal pressing prompting information.

[0107] In one possible implementation, before or after the step of comparing the measured sternal contour shape with a first preset sternal contour shape, the method further includes:

[0108] The measured sternal contour shape is compared with the second preset sternal contour shape. If the measured contour shape is above the second preset sternal contour shape, it is determined to be a third compression abnormality, and a third compression abnormality prompt message with increased force is output.

[0109] In this embodiment, the second preset sternal contour shape serves as a second reference. When the measured sternal contour shape is located above the second preset sternal contour shape—for example, when a certain number of points or line segments on the measured sternal contour shape are above the second preset sternal contour shape—it is determined to be a third abnormal pressure, and a third abnormal pressure prompt message is output. In this embodiment, "above" and "below" can be defined by the pressure direction. For example, when the pressure point is located on the abdomen and pressure is applied towards the back, it can be considered a downward pressure. Figure 3 In this context, the back contour is located below the abdominal contour, meaning the shape of the abdominal contour is located above the shape of the back contour.

[0110] In this embodiment of the disclosure, the third abnormal compression prompt information is used to indicate that the compression depth is too small and does not achieve the effect of cardiopulmonary resuscitation.

[0111] In one possible implementation, the measured sternal contour shape is compared with a second preset sternal contour shape. If the measured contour shape is below the second preset sternal contour shape, and the measured sternal contour shape is compared with a first preset sternal contour shape, if the measured contour shape is above the first preset sternal contour shape, then the compression is determined to be normal.

[0112] In this embodiment of the disclosure, if the measured contour shape is located below the second preset sternal contour shape and above the first preset sternal contour shape, it indicates that the compression amplitude is effective and the possibility of the user suffering a fracture or collapse is small. Therefore, when the measured contour shape is located above the first preset sternal contour shape and below the second preset sternal contour shape, it indicates that the compression is normal.

[0113] In one possible implementation, refer to Figure 9 As shown, the measured sternal contour shape is compared with a first preset sternal contour shape, and then the process further includes:

[0114] Obtain the sternal bending angle threshold corresponding to each preset position;

[0115] Based on the sternal bending angle threshold corresponding to each preset position, determine whether the bending angle of the inner line corresponding to the preset position meets the safety requirements.

[0116] If the sternal bending angle threshold corresponding to at least one of the preset positions is less than the bending angle of the corresponding inner line, a fourth abnormal pressing prompt message is sent.

[0117] Specifically, the bending angle threshold corresponding to the preset position can be obtained based on experience or experimentation, and the bending angle threshold corresponding to different preset positions can be different. In this embodiment, the bending angle of the inner line corresponding to the preset position can be obtained through any of the above embodiments, which will not be repeated here. When the bending angle threshold is less than the bending angle of the corresponding inner line, a fourth pressing abnormality prompt message is sent. The fourth pressing abnormality prompt message is used to indicate that the pressing force may be too large. Optionally, if the bending angle threshold of preset position a is less than the bending angle of the corresponding inner line, the preset position may not be safe enough and needs to be adjusted. In an exemplary embodiment, the fourth pressing abnormality prompt message is sent as an audio prompt, which is more direct. In another exemplary embodiment, the fourth pressing abnormality prompt message can also be displayed as an image or text. In an exemplary embodiment, the fourth pressing abnormality prompt message can be set alone, that is, it only includes this one prompt message. In another exemplary embodiment, the fourth pressing abnormality prompt message can be combined with any one or more of the above prompt messages. When combined with multiple prompt messages, the fourth pressing abnormality prompt message has a guiding function to indicate that a fracture has occurred at a specific preset position. Specifically, the first sensor corresponds to a preset position. When the bending angle at a certain first sensor is greater than a bending angle threshold, it indicates that there is a high probability of a fracture at that first sensor location. Optionally, a flashing indicator can be used at the corresponding position where the sternal contour shape is measured.

[0118] In this embodiment of the disclosure, by comparing the bending angle threshold corresponding to a preset position with the bending angle of the inner line, if the bending angle threshold of the sternum corresponding to at least one preset position is less than the bending angle of the corresponding inner line, a third or fourth press abnormality prompt message is sent, which can more accurately determine whether the specific position meets the safety requirements.

[0119] In one possible implementation, the step of obtaining the sternal curvature angle threshold corresponding to each of the preset positions includes:

[0120] Obtain the user's body indicator information, wherein the body indicator information includes one or more of the following: height, weight, body fat percentage, gender, chest size, and clothing size;

[0121] Determine a dataset of curvature angle thresholds that match the body metric information;

[0122] Obtain the bending angle threshold corresponding to each of the preset positions from the bending angle threshold dataset.

[0123] In this embodiment of the disclosure, the body indicator information may include one or more combinations of height, weight, body fat percentage, gender, chest size, and clothing size. In an exemplary embodiment, a correlation is established between body indicator information and a curvature angle threshold dataset. By obtaining the user's body indicator information, a curvature angle threshold dataset matching that body indicator information is determined. Optionally, the curvature angle threshold dataset can be categorized according to preset positions, with different preset positions corresponding to different curvature angle thresholds. Optionally, the correlation between body indicator information and the curvature angle threshold dataset may include the correlation between the numerical range of the body indicator information and the curvature angle threshold dataset.

[0124] In this embodiment of the disclosure, by obtaining the user's body indicator information, a bending angle threshold dataset that matches the body indicator information is determined, which is consistent with the user's physical condition and helps to generate more accurate prompts.

[0125] In one possible implementation, the method for obtaining the first preset sternal contour shape includes:

[0126] Based on the curvature angle threshold dataset, the first preset sternal contour shape is obtained;

[0127] Alternatively, the first preset sternal contour shape can be obtained by calibrating the user's physical indicators and effective compression data from historical cardiopulmonary resuscitation.

[0128] In this embodiment of the disclosure, a corresponding first preset sternal contour shape can be constructed based on the flexure angle threshold of the same user in the flexure angle threshold dataset. In an exemplary embodiment, the flexure angle threshold dataset includes the correlation between body indicator information and the flexure angle threshold dataset. Therefore, the first preset sternal contour shapes of users with the same type of body indicator information can be processed, for example, by taking the average value, to obtain the first preset sternal contour shape corresponding to that type of body indicator information. In another exemplary embodiment, the effective compression data corresponding to the same type of body indicator information can also be fitted based on historical effective CPR compression data to obtain the correlation between body indicator information and the first preset sternal contour shape. The corresponding first preset sternal contour shape is then found based on the specific user's body indicator information.

[0129] In one possible implementation, the second preset sternal contour shape is obtained based on the user's physical indicators and calibrated from historical ineffective CPR compression data. Similar to one method of obtaining the first preset sternal contour shape in the above embodiments, this disclosure embodiment can also perform fitting processing on ineffective compression data corresponding to the same type of physical indicator information based on historical ineffective CPR compression data to obtain the correlation between the physical indicator information and the second preset sternal contour shape. The corresponding second preset sternal contour shape is found based on the specific user's physical indicator information. Here, effective compression data refers to compression data that helps in CPR, and ineffective compression data refers to compression data that does not help in CPR.

[0130] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0131] Based on the same inventive concept, this application also provides a cardiopulmonary resuscitation (CPR) data processing device for implementing the aforementioned measurement method for CPR. The solution provided by this device is similar to the implementation described in the above method; therefore, the specific limitations in one or more CPR data processing device embodiments provided below can be found in the limitations of the measurement method for CPR described above, and will not be repeated here.

[0132] In one embodiment, such as Figure 10 As shown, a cardiopulmonary resuscitation data processing device 100 is provided, the device comprising:

[0133] The first sensor 101 is disposed at multiple preset positions on the outer side of the user's sternum; wherein, the preset positions include at least both sides of the center of the sternum.

[0134] Each of the first sensors includes at least a bending component, the bending component including an inner wire, the outer side of which is wrapped with a sheath made of a spiral coil;

[0135] The plurality of the first sensors are configured to respectively collect the displacement of the corresponding inner wire of the corresponding sheath when it is compressed;

[0136] The first processing unit 103 is configured to obtain the bending angle of the inner wire corresponding to each sheath based on the coil diameter of each sheath, the total number of coils and the width of the coil, and the displacement of the inner wire corresponding to the sheath.

[0137] The second sensor 105 is configured to collect depth change data at the pressing position;

[0138] The second processing unit 107 is configured to obtain the measured sternal contour shape of the user during pressing based on all the bending angles and depth change data of the inner lines.

[0139] The first analysis and judgment unit 109 is configured to compare and judge the measured sternal contour shape with a first preset sternal contour shape, and / or compare and judge the measured sternal contour shape with a second preset sternal contour shape.

[0140] The information output unit 111 is configured to output the comparison result output by the first analysis and identification unit, wherein the comparison result includes at least one of the following: normal pressing first abnormal pressing prompt information, second abnormal pressing prompt information, and third abnormal pressing prompt information.

[0141] In this embodiment, the change in inner displacement is represented by the change in the length of the bending component of the first sensor at each preset position. The bending angle represents the magnitude of the bending angle corresponding to the bending component. Since the preset positions of each first sensor are known, the position of the first sensor, the change in the length of the bending component, and the change in the angle can be simulated and displayed. By connecting the bending component data corresponding to adjacent first sensors, a partial contour of the user's sternum can be obtained. Optionally, the depth change data at the compression position can be combined to obtain the depth change at the compression position. This depth change is then combined with the partial contour obtained above to obtain the measured sternal contour shape of the user. In an exemplary embodiment, the distance data between the first sensors of the cardiopulmonary resuscitation device can be determined based on the model of the user's current cardiopulmonary resuscitation device. With breathing or external compression, the sternal contour changes, manifested as changes in each bending angle. The change in inner displacement is collected in the data. Based on the bending angle and depth change data, the user's sternal contour shape is determined. In this embodiment of the disclosure, the first preset sternal contour shape is used as a first reference. When the measured sternal contour shape is located below the first preset sternal contour shape, for example, when a certain number of points or line segments on the measured sternal contour shape are located below the first preset sternal contour shape, it is determined to be a first pressing abnormality, and a first pressing abnormality prompt message is output.

[0142] The aforementioned cardiopulmonary resuscitation (CPR) measuring device acquires the displacement of the corresponding inner line through first sensors at multiple preset positions. Based on the coil diameter, total number of coils, and width of the sheath of the first sensor's bending component, and the displacement of the inner line corresponding to the sheath, it obtains the bending angle of the inner line corresponding to each sheath. Combined with depth change data at the compression position, the device further determines the user's measured sternal contour shape. Compared to traditional flexible sensors, the bending angle and inner line displacement changes determined in this embodiment have better linearity and resolution. Therefore, this embodiment can more accurately determine the user's measured sternal contour shape. When the measured contour shape is below the first preset sternal contour shape, a first compression anomaly warning message is output to alert the user that the sternum may have collapsed or fractured.

[0143] In one possible implementation, the first analysis and judgment unit is further configured to determine a second compression abnormality if the measured contour shape intersects with the first preset sternal contour shape.

[0144] The information output unit is configured to output a second press abnormality prompt message, which is different from the first press abnormality prompt message.

[0145] In one possible implementation, the first analysis and judgment unit is further configured to determine a third compression abnormality if the measured contour shape is located above the second preset sternal contour shape.

[0146] The information output unit is configured to output a third abnormal pressing prompt message indicating increased force.

[0147] In one possible implementation, the first analysis and judgment unit is configured to compare the measured sternal contour shape with a second preset sternal contour shape, and if the measured contour shape is below the second preset sternal contour shape, and to compare the measured sternal contour shape with a first preset sternal contour shape, and if the measured contour shape is above the first preset sternal contour shape, then the compression is determined to be normal.

[0148] In one possible implementation, the first processing unit is further configured to obtain a bending angle threshold of the sternum corresponding to each of the preset positions;

[0149] The first analysis and judgment unit is further configured to determine whether the bending angle of the inner line corresponding to each preset position meets the safety requirements based on the bending angle threshold of the sternum corresponding to each preset position.

[0150] If the sternal bending angle threshold corresponding to at least one of the preset positions is less than the bending angle of the corresponding inner line, then a fourth abnormal pressing prompt message is sent.

[0151] The information output unit is also configured to output the fourth abnormal press prompt information.

[0152] In one possible implementation, the step of obtaining the sternal curvature angle threshold corresponding to each of the preset positions includes:

[0153] Obtain the user's body indicator information, wherein the body indicator information includes one or more of the following: height, weight, body fat percentage, gender, chest size, and clothing size;

[0154] Determine a dataset of curvature angle thresholds that match the body metric information;

[0155] Obtain the bending angle threshold corresponding to each of the preset positions from the bending angle threshold dataset.

[0156] In one possible implementation, the first preset sternal contour shape is obtained by means of:

[0157] Based on the curvature angle threshold dataset, the first preset sternal contour shape is obtained;

[0158] Alternatively, the first preset sternal contour shape can be obtained by calibrating the user's physical indicators and effective compression data from historical cardiopulmonary resuscitation.

[0159] In one possible implementation, the second preset sternal contour shape is obtained based on the user's physical indicators and calibrated from historical data on ineffective CPR compressions.

[0160] Each module in the aforementioned cardiopulmonary resuscitation data processing device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the corresponding operations of each module.

[0161] In one embodiment, a cardiopulmonary resuscitation device 800 is provided, referenced Figure 8As shown, the cardiopulmonary resuscitation (CPR) measuring device and body, as described in any of the above embodiments, wherein the body is a wearable defibrillator or chest strap. The wearable defibrillator is worn directly on the patient's body to provide emergency defibrillation treatment in the event of cardiac arrest or arrhythmia, providing immediate medical care. A wearable defibrillator typically consists of the following components: a defibrillator main unit containing an energy storage and release system for generating a high-energy electric shock to restore a normal heart rhythm. In an exemplary embodiment, the CPR measuring device includes: an embodiment of the CPR measuring method described above, where the displacement of the corresponding inner wire is acquired through multiple preset positions of first sensors 801, and the bending angle of the inner wire corresponding to each sheath is obtained based on the coil diameter of the sheath of the first sensor bending component, the total number of coils, the width of the coil, and the displacement of the inner wire corresponding to the sheath. Combined with depth change data at the compression position, the user's measured sternal contour shape is determined. Compared to traditional flexible sensors, the bending angle and the change in inner line displacement determined by the embodiments of this disclosure have better linearity and resolution. The linearity refers to the linear relationship between the change in inner line displacement and the bending angle. Therefore, the embodiments of this disclosure can more accurately determine the user's measured sternal contour shape. When the measured contour shape is below the first preset sternal contour shape, a first compression anomaly warning message is output to alert the user that the sternum may collapse or fracture. In another exemplary embodiment, the first processing unit in the cardiopulmonary resuscitation measuring device is further configured to acquire a bending angle threshold of the sternum corresponding to each preset position; the first analysis and judgment unit is further configured to determine, based on the bending angle threshold of the sternum corresponding to each preset position, whether the bending angle of the inner line corresponding to that preset position meets safety requirements; if the bending angle threshold of the sternum corresponding to at least one preset position is less than the bending angle of the corresponding inner line, a fourth compression anomaly warning message is sent; the information output unit is further configured to output the fourth compression anomaly warning message.

[0162] It is recommended here to supplement the explanation of the function of the cardiopulmonary resuscitation device with some content in the measurement method.

[0163] A chest strap is typically used in conjunction with a portable external defibrillator (PAF). A PAF mainly consists of a main unit and electrode pads. When a user collapses due to cardiac arrhythmia, the chest strap is placed on the user, and the electrode pads are attached to the user's chest. Assistance is provided through defibrillation and cardiopulmonary resuscitation (CPR) as prompted and needed. During chest compressions, the change in internal displacement is acquired via a first sensor, and the bending angle represents the magnitude of the bending angle corresponding to the bending component. Since the preset positions of each first sensor are known, the positions of the first sensors, the changes in the length of the bending component, and the angle changes can be simulated and displayed. By connecting the bending component data corresponding to adjacent first sensors, a partial contour of the user's sternum can be obtained. Optionally, depth change data at the compression position can be combined to obtain the depth change at the compression position. This depth change is then combined with the aforementioned partial contour to obtain the measured shape of the user's sternum. In an exemplary embodiment, the distance data between the first sensors of the CPR device can be determined based on the model of the user's current CPR device. With breathing or external compression, the sternum contour changes, manifested as changes in various bending angles. The change in internal displacement is collected in the data, and the shape of the user's sternum is determined based on the aforementioned bending angle and depth change data. In this embodiment of the disclosure, the first preset sternal contour shape serves as a first reference. When the measured sternal contour shape is located below the first preset sternal contour shape—for example, when a certain number of points or line segments on the measured sternal contour shape are below the first preset sternal contour shape—it is determined to be a first pressing abnormality, and a first pressing abnormality prompt message is output. In one possible implementation, the pressing abnormality prompt messages, such as the first pressing abnormality prompt message, the second pressing abnormality prompt message, the third pressing abnormality prompt message, and the fourth pressing abnormality prompt message, can be displayed or heard on the host computer, or can be prompted in other ways; this disclosure does not limit this.

[0164] In one exemplary embodiment, multiple first sensors are connected end-to-end (or tail-to-tail) and placed together on both sides of the center of the sternum of the smart vest, which can reduce the mutual interference caused by the structural stretching of the multiple first sensors.
