[0026] The target compression depth is determined based on the body characteristic parameters.

[0027] Secondly, this application also provides a cardiopulmonary compression prompting device, the device comprising:

[0028] The acquisition module is used to acquire real-time acceleration feedback values ​​during cardiopulmonary compression in response to compression operations of the cardiopulmonary compression aid at the target compression frequency.

[0029] The determination module is used to determine the real-time pressure depth corresponding to the real-time acceleration feedback value at the target pressure frequency based on the mapping relationship between the pressure frequency, the acceleration feedback value range, and the pressure depth.

[0030] The processing module is used to output a prompt indicating the real-time pressing depth.

[0031] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0052] 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.

[0053] The cardiopulmonary compression prompting method provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, the CPR aid 102 communicates with the server 104 via a network. The server 104 executes the CPR prompting method provided in this application. Specifically, in response to a compression operation on the CPR aid at a target compression frequency, the server 104 acquires the real-time acceleration feedback value during the CPR process; and based on the mapping relationship between compression frequency, acceleration feedback value range, and compression depth, determines the real-time compression depth corresponding to the real-time acceleration feedback value at the target compression frequency, so as to output a prompt of real-time compression depth to the rescuer.

[0054] In one embodiment, such as Figure 2 As shown, a cardiopulmonary compression prompting method is provided, which is applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0055] S202, in response to the compression operation of the cardiopulmonary compression aid at the target compression frequency, acquires the real-time acceleration feedback value during the cardiopulmonary compression process.

[0056] The cardiopulmonary compression assist device is equipped with an acceleration sensor. When the rescuer compresses the cardiopulmonary compression assist device at the target compression frequency, the acceleration sensor detects the acceleration value fed back by the compression operation, and can obtain the real-time acceleration feedback value.

[0057] In some embodiments, the CPR aid is communicatively connected to a display device. By setting a target compression frequency in the display device, the CPR aid can provide compression frequency prompts according to the target compression frequency, thereby ensuring that the rescuer can achieve the target compression frequency when performing CPR and improving the success rate of resuscitation.

[0058] The compression frequency prompt can be provided through sound and / or flashing colors. For example, if the target compression frequency is 100 compressions per minute, the CPR aid can emit a preset frequency of 100 compressions per minute, specifically a "beep" sound.

[0059] It should be noted that when the compression frequency is indicated by sound and flashing color, the sound emitted by the CPR aid is simultaneous with the flashing color to ensure that both are indicating to the rescuer at the set compression frequency.

[0060] S204, based on the mapping relationship between pressing frequency, acceleration feedback value range and pressing depth, determines the real-time pressing depth corresponding to the real-time acceleration feedback value at the target pressing frequency.

[0061] The mapping relationship between pressing frequency, acceleration feedback value range, and pressing depth can be understood as follows: when pressing based on the pressing frequency, in order to achieve the corresponding pressing depth, the acceleration feedback value detected by the acceleration sensor must be within the corresponding acceleration feedback value range. The mapping relationship includes, but is not limited to, the acceleration feedback ranges corresponding to pressing frequencies of 80 times per minute, 90 times per minute, 100 times per minute, 110 times per minute, and 120 times per minute, and pressing depths of 1cm-8cm.

[0062] For example, at a pressing frequency of 100 times per minute, to achieve a pressing depth of 5cm, the acceleration feedback value needs to be between 26,000 and 27,000; at a pressing frequency of 100 times per minute, to achieve a pressing depth of 4cm, the acceleration feedback value needs to be between 22,500 and 23,500.

[0063] It should be noted that the accelerometer provided in this application can provide acceleration feedback values ​​in the x, y, and z directions, but this application uses the acceleration feedback value in the z direction and the mapping relationship to determine the pressing depth.

[0064] In some embodiments, for different pressing frequencies, the corresponding mapping relationships can be set in different databases for easy and quick retrieval of the mapping relationships. For example, the mapping relationship corresponding to a pressing frequency of 100 times per minute can be stored in a different database than the mapping relationship corresponding to a pressing frequency of 80 times per minute.

[0065] S206 outputs real-time pressure depth prompts.

[0066] In some embodiments, the CPR aid is communicatively connected to a display device, allowing the rescuer to see the real-time compression depth on the display device; or, while the display device shows the real-time compression depth, the CPR aid can also provide voice prompts, preventing the rescuer from being unable to see the display device and thus ensuring that the rescuer can promptly know the real-time compression depth during the CPR process.

[0067] In some embodiments, the CPR aid is equipped with multiple indicator lights. The server controls the indicator lights to flash according to preset colors based on the real-time compression depth; the number of indicator lights flashing with color is the same as the real-time compression depth. Specifically, the server compares the real-time compression depth with a preset depth range to determine the real-time depth range in which the real-time compression depth falls; the preset depth range includes the real-time depth range; the server controls multiple indicator lights on the CPR aid, each with the same value as the real-time compression depth, to flash according to the color corresponding to the real-time depth range.

[0068] For example, if the real-time compression depth is 3cm, and the corresponding real-time depth range is determined to be 1cm-4cm, with the corresponding color being orange, then the server controls the three indicator lights on the CPR aid to flash orange as a warning. If the real-time compression depth is 6cm, and the corresponding real-time depth range is determined to be 5cm-7cm, with the corresponding color being green, then the server controls the six indicator lights on the CPR aid to flash green as a warning; the number of indicator lights flashing according to color is the same as the magnitude of the real-time compression depth.

[0069] In summary, based on Figure 2 The method shown, by setting a mapping relationship between compression frequency, compression depth, and acceleration feedback value ranges, allows for the direct determination of real-time compression depth during CPR based on real-time acceleration feedback values. This provides a real-time compression depth prompt to the rescuer, solving the problem of rescuers causing bodily harm to the victim due to a lack of knowledge of compression depth. Furthermore, when rescuers perform CPR based on the prompted real-time compression depth and their personal experience, the success rate of resuscitation can be improved.

[0070] In one embodiment, such as Figure 3 The diagram illustrates a process for determining the real-time compression depth corresponding to the real-time acceleration feedback value at a target compression frequency, based on a mapping relationship between compression frequency, acceleration feedback value range, and compression depth. This method is then applied to… Figure 1 Taking server 104 as an example, the following steps are included:

[0071] S302, based on the real-time acceleration feedback value, the target pressing frequency, and the mapping relationship, obtains the first pressing depth.

[0072] In some embodiments, a corresponding mapping relationship can be obtained based on the target pressing frequency; based on the real-time acceleration feedback value, a matching real-time acceleration feedback value range can be determined from the mapping relationship to obtain the first pressing depth; wherein, the mapping relationship can be obtained from the corresponding database based on the target pressing frequency.

[0073] For example, if the target compression frequency is 100 times per minute, the corresponding mapping relationship includes, but is not limited to: when the compression depth is 5cm, the corresponding acceleration feedback value needs to be between 26000-27000; when the compression depth is 4cm, the corresponding acceleration feedback value needs to be between 22500-23500, and so on. If the real-time acceleration feedback value is 26520, the real-time acceleration feedback value range determined from this mapping relationship is 26000-27000. Therefore, the first compression depth can be determined to be 5cm.

[0074] S304, Obtain the second compression depth, which is determined by the double integral of the acceleration vector function during cardiopulmonary compression.

[0075] The acceleration vector function is a time-based vector function of the acceleration feedback value during CPR, which can be represented as a(t). The second compression depth can be obtained by double integration of a(t). The velocity vector function can be obtained by integrating a(t), and the displacement can be obtained by integrating the velocity vector function. This displacement is the second compression depth.

[0076] S306, if the first pressing depth and the second pressing depth are the same, determine the first pressing depth or the second pressing depth as the real-time pressing depth.

[0077] In summary, based on Figure 3 The method shown improves the accuracy of real-time compression depth by comparing the compression depth obtained based on mapping and the compression depth obtained based on calculus during CPR. This allows rescuers to increase the success rate of CPR by combining accurate real-time compression depth with their personal experience.

[0078] In one embodiment, if the first compression depth and the second compression depth are different, the process returns to S202 until the first compression depth and the second compression depth are the same, in order to ensure the accuracy of the real-time compression depth determination. In this way, when rescuers perform CPR based on the accurate real-time compression depth and their personal experience, the success rate of resuscitation can be improved.

[0079] In one embodiment, such as Figure 4 The diagram illustrates a process for obtaining real-time acceleration feedback values ​​during cardiopulmonary compression, and how this method can be applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0080] S402, set the feedback duration and the feedback cycle within the feedback duration.

[0081] S404 obtains multiple acceleration feedback values ​​within the feedback duration based on the feedback period.

[0082] The feedback duration can be 10 seconds, 30 seconds, 1 minute or other values, and the feedback period can be 1 second, 5 seconds, 10 seconds or other values. For example, if the feedback duration is 30 seconds and the feedback period is 5 seconds, then multiple acceleration feedback values ​​are obtained every 5 seconds through the accelerometer within 30 seconds.

[0083] S406 obtains real-time acceleration feedback values ​​based on multiple acceleration feedback values.

[0084] In some embodiments, the average value of multiple acceleration feedback values ​​can be determined as the real-time acceleration feedback value; or, the weighted sum of multiple acceleration feedback values ​​can be determined as the real-time acceleration feedback value.

[0085] In summary, based on Figure 4 The method shown improves the accuracy of real-time acceleration feedback values ​​by setting a feedback duration and a feedback cycle within that duration, and by obtaining real-time acceleration feedback values ​​based on multiple acceleration feedback values ​​within that duration. This allows for accurate determination of the real-time compression depth corresponding to the target compression frequency based on the real-time acceleration feedback value from a mapping relationship. When the real-time compression depth is displayed to the rescuer, the rescuer can accurately know the actual compression depth during CPR, resolving the problem of rescuers causing injury to the recipient due to a lack of knowledge of the compression depth. Furthermore, by combining the suggested compression depth with personal experience, the success rate of CPR can be improved.

[0086] In one embodiment, such as Figure 5 The diagram shows a flowchart of a cardiopulmonary compression (CPR) prompting method, which is applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0087] S502, obtain the target compression depth.

[0088] S504 outputs a force prompt when the real-time pressing depth does not reach the target pressing depth.

[0089] The target compression depth is the standard compression depth. The target compression depth varies depending on the individual being compressed. For example, for adults, the target compression depth is 5cm-6cm; for children, the target compression depth is 2cm-3cm.

[0090] In some embodiments, if the real-time pressing depth is greater than the target pressing depth, a prompt indicating that the pressing force has decreased is output; if the real-time pressing depth is less than the target pressing depth, a prompt indicating that the pressing force has increased is output.

[0091] In some embodiments, the cardiopulmonary compression aid is communicatively connected to a display device. When it is determined that the real-time compression depth has not reached the target compression depth, the display device can show a prompt indicating that the compression force has increased or decreased, making it convenient for the rescuer to check.

[0092] In some embodiments, when it is determined that the real-time compression depth has not reached the target compression depth, the server can control the CPR aid to issue a force prompt voice to prompt the rescuer to increase or decrease the compression force; in this way, even if the rescuer cannot see the force prompt in time, he can know the force prompt in time through voice, which provides the timeliness of the force prompt.

[0093] In summary, Figure 5 In the illustrated embodiment, by determining whether the real-time compression depth has reached the target compression depth, it can be determined whether the rescuer has met the compression requirements. If the rescuer has not met the compression requirements, a force prompt is output so that the rescuer can adjust the compression force to make the real-time compression depth reach the target compression depth. In this way, when the rescuer performs CPR based on the real-time compression depth, the success rate of CPR can be improved.

[0094] In one embodiment, the target compression depth can be obtained by responding to an input operation of compression depth at a target compression frequency. Specifically, the CPR aid is communicatively connected to a display device, where the rescuer can set the target compression depth. Thus, during actual compressions, if it is determined that the real-time compression depth has not reached the target depth, the display device can show a force prompt, and / or the CPR aid can output a force prompt voice message.

[0095] In one embodiment, such as Figure 6 The diagram illustrates a process for obtaining the target compression depth, which is then applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0096] S602, Obtain the body characteristic parameters of the object being pressed.

[0097] S604 determines the target compression depth based on body characteristic parameters.

[0098] Among them, body characteristic parameters refer to the body characteristic parameters of the person being compressed. Specifically, body characteristic parameters may include, but are not limited to: the distance between the front and back of the sternum, the lateral width of the chest, the chest circumference, the chest volume, and the weight. Different body characteristic parameters correspond to different target compression depths. For example, for a person being compressed with a distance between the front and back of the sternum of 15.24cm to 20.32cm, the target compression depth can be 3.175cm to 4.445cm; for a person being compressed with a distance between the front and back of the sternum of 30.48cm to 35.56cm, the target compression depth can be 5.715cm to 6.985cm.

[0099] In summary, based on Figure 6As shown, during CPR, by combining the body characteristic parameters of the person being compressed to determine the target compression depth, it is possible to accurately determine whether the real-time compression depth has reached the target compression depth that matches the body characteristics of the person being compressed, thus improving the accuracy of the output force prompt.
