Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation compression depth detection, and in particular to an interactive cardiopulmonary resuscitation compression depth detection device and a detection method. Background Art

[0002] Cardiopulmonary resuscitation is an emergency life-saving measure for cardiac arrest or respiratory arrest. It temporarily maintains blood circulation and oxygen supply through chest compressions and artificial respiration to buy time for professional treatment. The compression position of cardiopulmonary resuscitation is the lower half of the sternum and at the midpoint of the line connecting the two nipples. The compression depth for adults is 5-6cm and the speed is 100-120 times per minute. The compression depth for children is about 5 and the speed is also 100-120 times per minute. Infants use two-finger compressions, the compression depth is about 4cm, and the speed is 100-120 times per minute. The frequency of artificial respiration is generally 30 compressions and two breaths for single-person cardiopulmonary resuscitation.

[0003] The above-mentioned standard CPR operation is difficult for some non-professionals to perform standard CPR actions in one go when encountering an emergency. Standard CPR actions include compression depth, compression frequency, compression angle, and blowing frequency. Even for professionals, when encountering sudden emergencies, it is easy to find it difficult to perform correct CPR actions due to nervousness or noisy surroundings. Based on this, it is necessary to design an interactive CPR compression depth detection device to solve the above problems. Summary of the invention

[0004] The present invention provides an interactive cardiopulmonary resuscitation compression depth detection device, which collects the descent depth, compression frequency and compression angle information of the compression position during cardiopulmonary resuscitation through a collection device, compares the collected information with pre-stored standard information, and sends different control signals according to the comparison results to control the prompt device to perform different prompt operations, so that personnel can accurately perform standard cardiopulmonary resuscitation actions.

[0005] The technical problem solved by the present invention is achieved by adopting the following technical solutions: The present invention provides an interactive cardiopulmonary resuscitation compression depth detection device, comprising A collection device for collecting information on the depth of compression, compression frequency and compression angle during cardiopulmonary resuscitation; A processor connected to the acquisition device, used to compare the descent depth, compression frequency and compression angle information collected by the acquisition device with pre-stored standard cardiopulmonary resuscitation information, and send different control signals according to the comparison results; A prompting device, connected to a processor, is configured to receive different control signals sent by the processor, and different ones of the control signals are used to control the prompting device to perform different prompting operations.

[0006] Preferably, the acquisition device is an acceleration sensor placed at the pressing position during cardiopulmonary resuscitation.

[0007] Preferably, the acquisition device includes two acceleration sensors. One of the acceleration sensors is placed at the pressing position during cardiopulmonary resuscitation, and the other acceleration sensor is placed on the human body avoiding the pressing position. The processor uses the displacement difference value of the descending depth calculated by the two acceleration sensors as the descending depth of the pressing position during cardiopulmonary resuscitation.

[0008] Preferably, it further includes a pulse sensor wearable on the human wrist, and an output end of the pulse sensor is connected to an input end of the processor.

[0009] Preferably, the processor and the prompting device are integrally provided on a main unit. The pre-stored standard information is stored in an information storage device provided inside the main unit. The information storage device stores information on the standard pressing depth, pressing frequency, and pressing angle corresponding to different age categories during cardiopulmonary resuscitation. An information input device is further provided on the cardiopulmonary main unit for inputting the age category parameter of the person to receive cardiopulmonary resuscitation. Both the information input device and the information storage device are connected to the processor.

[0010] On the other hand, the present invention further provides an interactive depth detection method for cardiopulmonary resuscitation pressing, including: An acquisition step of receiving the descending depth and pressing angle information of the pressing position during cardiopulmonary resuscitation transmitted by the acquisition device; A processing step of comparing the descending depth, pressing frequency, and pressing angle information of the pressing position during cardiopulmonary resuscitation with the pre-stored standard cardiopulmonary resuscitation information, and sending different control signals according to the comparison result, where the control signals are used to control the prompting device to perform different prompting operations.

[0011] Preferably, a preprocessing step is further provided before the processing step; A preprocessing step of using the descending depth difference value obtained by the two acceleration sensors of the acquisition device as the descending depth information of the pressing position during cardiopulmonary resuscitation, where one of the two acceleration sensors of the acquisition device is placed at the pressing position of human cardiopulmonary resuscitation, and the other acceleration sensor is placed on the human body avoiding the pressing position during cardiopulmonary resuscitation.

[0012] Preferably, the acquisition step further includes acquiring the pulse signal of the human wrist.

[0013] Preferably, in the processing step, the pre-stored standard cardiopulmonary resuscitation information includes the cardiopulmonary resuscitation standard compression depth, compression frequency, and compression angle information corresponding to different age type parameters. In the processing step, the compression depth, compression frequency, and compression angle information of the compression position during cardiopulmonary resuscitation are compared with the pre-stored standard cardiopulmonary resuscitation information. Specifically, the standard cardiopulmonary resuscitation information with the same age type parameters as the person to receive cardiopulmonary resuscitation is compared with the compression depth, compression frequency, and compression angle information obtained during cardiopulmonary resuscitation. The obtaining step further includes obtaining the age type parameters of the person to receive cardiopulmonary resuscitation.

[0014] The beneficial effects of the present invention are as follows: Through the acquisition device, the compression depth, compression frequency, and compression angle information of the compression position during cardiopulmonary resuscitation are collected, and the collected information is compared with the pre-stored standard information.

[0015] The acquisition device measures the compression depth by setting two acceleration sensors. One acceleration sensor is installed at the cardiopulmonary resuscitation compression position of the human body, and the other acceleration sensor is installed at the position of the human body avoiding cardiopulmonary resuscitation. Thus, the difference value of the two pressure sensors can accurately measure the compression depth. At the same time, based on the periodic signal change, the pressure sensor can output the compression frequency information. At the same time, the acceleration sensor can also monitor whether the compression angle is perpendicular to the direction of the human body.

[0016] By setting a pulse sensor, it is possible to detect whether there is a pulse signal of the human body during cardiopulmonary resuscitation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0021] In order to make the innovative points of the present invention easier to be understood by those skilled in the art, first, the concepts of the prior art related to the present invention will be introduced. Cardiopulmonary resuscitation is a well-known effective emergency life-saving measure for cardiac arrest or respiratory arrest. Through external chest compression and artificial respiration, blood circulation and oxygen supply are temporarily maintained to gain time for professional treatment. The compression position of cardiopulmonary resuscitation is the lower half of the sternum and at the midpoint of the line connecting the two nipples. Among the compression parameters of cardiopulmonary resuscitation for adults and infants, only the compression depth is different. The compression depth for adults is 5 - 6 cm, and for infants, two fingers are used for compression with a compression depth of about 4 cm. The compression rate for both adults and infants is 100 - 120 times per minute, and the frequency of artificial respiration is generally 30 compressions and 2 breaths for single-person operation of cardiopulmonary resuscitation. In order to assist personnel to perform correct cardiopulmonary resuscitation actions in an emergency, the present invention adopts the following solutions to solve the problem.

[0022] On the one hand, refer to Figures 1 - 3, the present invention provides a depth detection device for interactive cardiopulmonary resuscitation (CPR) pressing, including: a collection device, a processor 101, and a prompting device. The collection device is used to collect the depth of position descent, the pressing frequency, and the pressing angle information during CPR. The processor 101 is connected to the collection device and is used to compare the depth of descent, the pressing frequency, and the pressing angle information collected by the collection device with the pre-stored standard CPR information, and send different control signals according to the comparison results. The prompting device is connected to the processor 101 and is used to receive the different control signals sent by the processor 101. The different control signals are used to control the prompting device to perform different prompting operations. Specifically, the collection device can be an acceleration sensor. The acceleration sensor can be used to collect the angle of pressing during CPR (the direction of acceleration is the direction of the applied pressing force), the pressing frequency (when pressing on the chest position, the acceleration sensor will synchronously and periodically move up and down with the pressed chest, and the pressing frequency can be obtained through the periodic change of the acceleration sensor), and the depth of descent (the speed can be obtained by integrating the acceleration, and the moving distance, that is, the depth of descent, can be obtained by integrating the speed). Therefore, using the acceleration sensor as the collection device to collect whether the action information during CPR is standard is the best choice. After processing the signal of the acceleration sensor, the processor 101 can compare it with the pre-stored standard CPR information to know what defects exist in the operation during the CPR of the person. The prompting device is controlled by the controller to prompt the person to perform standard actions. For example, if the processor 101 determines that the pressing frequency of the current person is slower, it controls the prompting device to perform a voice broadcast prompt "Please press faster", and display the text "Please press faster" on the display screen. Similarly, if the processor 101 determines that the pressing depth at the pressing position of the current person is smaller, it performs a voice broadcast prompt "Please press harder", and display the text "Please press harder" on the display screen. Similarly, if it is determined that the pressing angle of the current person is incorrect, it performs a voice broadcast prompt "Please press vertically", and display the text "Please press vertically" on the display screen. As can be seen from the above, the specific implementation method of the prompting device can be a touch display screen 102 and a speaker 103.

[0023] Further, referring to Figure 4 , since the person receiving CPR will often shake the whole body when being pressed, this shake will cause a large error in the pressing depth information collected by the acceleration sensor. Based on this, the collection device can be set to two acceleration sensors. One acceleration sensor is placed at the pressing position of CPR, and the other acceleration sensor is placed on the human body avoiding the pressing position, such as Figure 1 and Figure 2Among them, the two acceleration sensors are respectively named the first acceleration sensor 2 and the second acceleration sensor 3. The first acceleration sensor 2 is placed inside the rubber block 4 at the position on the human body that needs to be pressed. The second acceleration sensor 3 is placed on the human body at a position avoiding the pressing through a rubber pad 5. Since the shaking of the human body caused by pressing will not only cause errors in the first acceleration sensor 2, but also synchronously drive the second acceleration sensor 3 to generate corresponding signals, and the signals generated by the second acceleration sensor 3 are all generated by the body shaking, so the difference value between the signals of the first acceleration sensor 2 and the second acceleration sensor 3 is the signal change caused by the pressing of the person. Thus, the change in the pressing depth during cardiopulmonary resuscitation can be accurately obtained based on this difference value.

[0024] Furthermore, referring to Figure 1 and Figure 5 , the present invention is also provided with a pulse sensor 7. Specifically, the pulse sensor 7 has several types such as photoelectric type, piezoelectric type, capacitive type, and bioelectric type. It is fixed to the wrist of the human body through a bracelet 6. The output end of the pulse sensor 7 is connected to the input end of the processor 101. When the heart of the human body resumes beating, the processor 101 controls the prompting device to give a broadcast prompt, such as "The heart has resumed normal beating", and at the same time, the display screen displays corresponding text.

[0025] Specifically, referring to Figure 1 and Figure 6 , in the above text, the processor 101 and the prompting device are concentrated on a main unit 1. The prompting device is specifically the display screen and the speaker 103 on the surface of the main unit 1. Inside the main unit 1, in addition to the processor 101, there is also an information storage device for storing the standard pressing depth, pressing frequency, and pressing angle information corresponding to different age categories. Among them, different age categories include infants and non-infants (children and adults). The standard pressing depths corresponding to different age categories are different. For infants, it is about 4 cm, and for non-infants, it is about 5 cm. In order to facilitate the input of the age category of the person to be given cardiopulmonary resuscitation, the display screen can be used as an information input device, that is, before performing cardiopulmonary resuscitation, there are two modes, infant mode and non-infant mode, on the display screen. The person touches the display screen to select the mode, so as to facilitate the processor 101 to call the corresponding standard cardiopulmonary resuscitation operation information for comparison with the information collected by the collection device.

[0026] On the other hand, referring to Figure 7 , the present invention also provides an interactive cardiopulmonary resuscitation pressing depth detection method, including: an acquisition step of receiving the information of the downward depth, pressing frequency, and pressing angle of the pressing position during cardiopulmonary resuscitation transmitted by the collection device; Processing step: comparing the depth of depression, compression frequency, and compression angle information at the compression position during cardiopulmonary resuscitation with pre-stored standard cardiopulmonary resuscitation information, and issuing different control signals according to the comparison result, where the control signal is used to control the prompting device to perform different prompting operations.

[0027] Further, referring to Figure 8 , there is also provided before the processing step; Preprocessing step: using the depth difference value obtained by two acceleration sensors of the acquisition device as the depth of depression information of the compression position during cardiopulmonary resuscitation, where one of the two acceleration sensors of the acquisition device is placed at the compression position of human cardiopulmonary resuscitation, and the other acceleration sensor is placed on the human body avoiding the compression position during cardiopulmonary resuscitation.

[0028] Further, referring to Figure 9 , in the processing step, the pre-stored standard cardiopulmonary resuscitation information includes the standard compression depth, compression frequency, and compression angle information corresponding to different age category parameters. In the processing step, comparing the depth of depression, compression frequency, and compression angle information at the compression position during cardiopulmonary resuscitation with the pre-stored standard cardiopulmonary resuscitation information specifically means comparing the standard cardiopulmonary resuscitation information with the same age category parameter as the person to be given cardiopulmonary resuscitation with the depth of depression, compression frequency, and compression angle information obtained during cardiopulmonary resuscitation. The acquisition step also includes acquiring the age category parameter of the person to be given cardiopulmonary resuscitation.

[0029] Further, in the above acquisition step, it also includes acquiring the pulse signal of the human wrist. When the processor 101 acquires the pulse signal of the human body, it issues a control signal to control the prompting device to perform corresponding prompting actions.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
