Description

The present disclosure belongs to the field of detection equipment, and specifically relates to a cardiopulmonary resuscitation operation detection auxiliary system and a calibration device.

Cardiopulmonary arrest is the most urgent clinical situation, and emergency cardiopulmonary resuscitation operations are widely used in emergency scenarios of cardiopulmonary arrest. In emergency compression, two parameters are more important, one is the frequency of compression, and the other is the depth of compression. In 2010, the International Resuscitation Federation and the American Heart Association put forward the standard to ensure that the frequency of chest compressions is more than 100 times per minute, and the compression depth is more than 5 cm.

For the detection of compression frequency, good statistics can be achieved at present. For the depth of pressing, there are some technologies that rely on the acceleration sensor to integrate with the movement time for calculation.

For example, when the pressing depth is more than 5 cm, the required detection error is less than ± 0.5 cm. At present, the accuracy of the acceleration sensor is often difficult to ensure the required detection accuracy.

The preferred embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

As shown in Figure 1, an embodiment of the present disclosure provides a cardiopulmonary resuscitation operation detection system. The cardiopulmonary resuscitation operation detection system can detect the parameters during the cardiopulmonary resuscitation operation. The cardiopulmonary resuscitation operation detection system includes a calibration device 100 and a detection terminal 200.

As shown in FIG. 2, the calibration device 100 for detecting cardiopulmonary resuscitation operation includes a fixing member 101 and a marking member 102. During cardiopulmonary resuscitation, the fixing component 101 is used to fix the calibration device 100 to the rescuer's wrist. The marking component 102 is arranged on the fixing component 101 and is formed into a figure with predetermined size parameters, which serves as an optical beacon to facilitate identification in the video image of the calibration device 100. The marking component 102 includes a self-luminous structure and/or a reflective structure.

The figure formed by the marking component 102 and the size of the figure are pre-stored in the detection terminal to facilitate subsequent processing by the detection terminal. In this embodiment, the pattern formed by the marking member 102 is a circle, the diameter of the circle is determined, and the diameter of the circle is pre-stored in the detection terminal. In another solution, the graphic of the marking component 102 may be a rectangle or a square, and the side length of the rectangle or the square is pre-stored in the detection terminal. The graphic of the marking component 102 may also be of other specific shapes, as long as it has a certain size.

As shown in FIGS. 3 and 4, the marking member 102 includes a diffuse transmission strip 102a and a first light source 103. The diffuse transmission bar 102a can make the transmitted light form diffuse light, and the brightness of the light will not be too high. A first light source 103 is provided in the fixing part 101 of the calibration device. Optionally, the first light source 103 is an LED lamp. The light emitted by the LED lamp emits diffused light after passing through the diffuse transmission strip 102a, so that the brightness of the marking component 102 is greater than the brightness of the surrounding environment, which facilitates the identification of the marking component 102 in the image image of the calibration device 100. The diffused light will not be very bright, which can ensure accurate focus when shooting the calibration device 100.

According to an optional technical solution of the present disclosure, the number of the marking components 102 is multiple, which are arranged in sequence on the fixed component 101 to facilitate the recognition of the spatial posture of the calibration device 100. The multiple marking components 102 can also be set to different colors to improve the accuracy of spatial gesture recognition.

According to an optional technical solution of the present disclosure, the brightness of the first light source 103 is adjustable. The calibration device 100 further includes a brightness sensor 104 arranged on the fixing part 101 of the calibration device, and the brightness sensor 104 is used for detecting the brightness of the environment. The microprocessor 105 of the calibration device controls the brightness of the first light source 103 or controls the opening and closing of the first light source 103 according to the environmental brightness detected by the brightness sensor 104. For example, if the ambient brightness is lower than the preset threshold, the first light source 103 is turned on, and the ambient brightness is higher than the preset threshold, the first light source 103 is turned off.

According to an optional technical solution of the present disclosure, the marking component 102 further includes a reflective strip 102b and/or a fluorescent strip 102c. The reflective strip 102b and/or the fluorescent strip 102c form the pattern on the fixing part of the calibration device. When the power of the calibration device 100 is insufficient to turn on the first light source 103, the reflective strip 102b and/or the fluorescent strip 102c can be used as optical beacons.

As shown in FIG. 5, according to an optional technical solution of the present disclosure, the calibration device 100 further includes an orientation marking component 110 provided on the fixing component 101. If the graphic of the marking component 102 is a polygon, the orientation marking component 110 is used to distinguish the direction of the graphic. For example, the graphic of the marking member 102 is a rectangle, and the long side or the short side is set as a double strip, so that the long side and the short side can be distinguished for easy identification.

According to an optional technical solution of the present disclosure, the calibration device 100 further includes a three-axis acceleration sensor 106. The three-axis acceleration sensor 106 is arranged in the fixing part 101 of the calibration device, and can measure the pressing force during cardiopulmonary resuscitation. If the measured pressing force is too large, the calibration device 100 can give a reminder to the rescuer to avoid secondary injuries such as fractures. The three-axis acceleration sensor 106 can also confirm whether the cardiopulmonary resuscitation process is in progress, and record the duration of the cardiopulmonary resuscitation.

According to an optional technical solution of the present disclosure, the calibration device 100 further includes a Bluetooth module 107. The Bluetooth module 107 is used for Bluetooth connection with the detection terminal to perform data interaction. The calibration device 100 further includes a voice output module 108 and/or a vibration module 109. When the rescuer needs to be prompted, the voice output module 108 can output a prompt voice, and the vibration module 109 can generate vibration to prompt the rescuer.

The calibration device 100 may also be provided with operation buttons, such as up, down, left, and right buttons, confirmation keys, and cancel keys, which are used to select and confirm/cancel preset functions or operations in the calibration device 100.

The calibration device 100 may be a wristband, which is worn on the wrist of the rescuer during cardiopulmonary resuscitation. The calibration device 100 can also be a device that can be fixed to an arm, such as a watch or an arm guard. Preferably, the calibration device 100 is used to be worn on the wrist, because in this case the error between the movement distance of the bracelet and the movement distance of the palm is the smallest.

As shown in FIG. 6, the detection terminal 200 includes a camera module 201 and a processing module 202. The camera module 201 may be a camera, which is used to photograph the calibration device 100 and obtain real-time video images of the calibration device 100. The camera is preferably a high-definition camera, which can ensure the clarity of shooting the scene. When using the detection terminal 200 to photograph the calibration device 100, the detection terminal 200 may be fixed first to avoid unnecessary movement of the detection terminal 200 during the shooting process. Generally, the normal of the marking component 102 is basically aligned with the detection terminal 200. The processing module 202 determines the moving distance of the calibration device 100 according to the size of the marking member 102 and the image image of the calibration device. The movement distance of the calibration device 100 is the compression depth during cardiopulmonary resuscitation, and the compression depth measurement is achieved through the cooperation of the calibration device 100 and the detection terminal 200.

As shown in FIG. 7, specifically, the size of the marking member 102 is a certain value, and the camera module 201 takes pictures of the calibration device 100. The size parameters of the pattern formed by the marking component 102 are pre-stored in the detection terminal 200. When the calibration device 100 is not moving, the first sub-module 202a of the processing module 202 recognizes the image of the marking component 102 from the image image of the calibration device, and determines the first number of primitives corresponding to the size of the marking component 102. According to the size of the marking component 102 and the first number of graphic elements corresponding to the size of the marking component 102, the actual distance corresponding to the graphic element in the image image of the calibration device is determined.

As shown in FIG. 8, the graphic shape of the marking member 102 is a square as an example. The side length L of the marking member 102 is 2 cm. The first sub-module 202a of the processing module 202 determines from the image image of the calibration device that the square side corresponds to the first pixel number as 100, and the actual distance corresponding to the pixel in the image image of the calibration device is 0.02 cm.

When the rescuer presses and the calibration device 100 moves, the second sub-module 202b of the processing module 202 determines the upper limit image frame and the lower limit image frame from the image image of the calibration device. The second image element number corresponding to the movement distance of the calibration device is determined according to the upper limit image frame and the lower limit image frame.

As shown in Figure 9, when the calibration device 100 moves, the second sub-module 202b of the processing module 202 can identify the upper limit image frame and the upper limit image frame of a pressing operation from each image frame of the image image of the calibration device. Lower limit image frame. The number of picture elements between the upper limit bit and the lower limit bit of the marking component 102 in the upper limit image frame and the lower limit image frame is used as the second number of picture elements corresponding to the movement distance of the calibration device 100.

When the first press is performed, the image frame in the image when the calibration device 100 is not moving is used as the upper limit image frame of the first press; as the calibration device 100 moves down, the image element corresponding to the marking component 102 in the image image continues Move down; when the second sub-module 202b of the processing module 202 recognizes that the graphic element corresponding to the marking component 102 is no longer moving down, it uses an image frame at this time as the lower limit image frame of the first press. As the calibration device 100 moves up, when the second sub-module of the processing module 202 recognizes that the graphic element corresponding to the marking component 102 is no longer moving up, it uses an image frame at this time as the upper limit map of the second press Image frame; after the calibration device 100 moves down, and the second sub-module 202b of the processing module 202 recognizes that the graphic element corresponding to the marking component 102 no longer moves down, an image frame at this time is used as the second pressing down Extreme image frame. In such a loop, the second sub-module 202b of the processing module 202 can identify the upper limit image frame and the lower limit image frame corresponding to each press. According to the upper limit image frame and the lower limit image frame, the number of second picture elements corresponding to the movement distance of the calibration device 100 is determined each time it is pressed.

The third sub-module 202c of the processing module 202 determines the movement distance of the calibration device according to the actual distance corresponding to the graphic element in the image image of the calibration device and the second number of graphic elements.

For example, in one press, the processing module 202 determines that the second pixel number corresponding to the movement distance S of the calibration device 100 is 200, and the actual distance corresponding to the pixel in the image image of the calibration device is 0.02 cm, and the calibration device moves The distance S is 4cm. Let 4cm be the compression depth this time.

In an actual scenario, the normal line of the marking component 102 on the calibration device may not point to the detection terminal 200, that is, the detection terminal 200 photographs the calibration device in an oblique direction. At this time, the processing module 202 can determine from which direction the detection terminal 200 shoots the calibration device 100 according to the amount of image deformation of the marking component; according to the cosine relationship conversion of the corresponding angle, the processing module 202 determines the image element in the image image of the calibration device The corresponding actual distance. This design mainly relates to when a person wears the calibration device 100 for treatment, the plane where the marking component 102 of the calibration device is located is not necessarily perpendicular to the connection direction of the calibration device 100 and the detection terminal 200. When it is not vertical, the marking component 102 detected by the detection terminal 200 will form a certain distortion. For example, when the marking component is originally circular, when the plane of the marking component of the calibration device is not perpendicular to the connecting direction of the calibration device and the detection terminal, the detected marking component takes an oval shape. At this time, although the detection terminal knows the size of the marking component, for example, the diameter of the circle is 2 cm, the long axis of the ellipse in the detected image is 2 cm, and the short axis is less than 2 cm. At this time, the detection terminal needs to recognize the size of the actual marking component according to the actual image captured, for example, the long axis of the ellipse represents the diameter of the circle. When a circle becomes an ellipse, it is relatively simple, but when a rectangle or polygon is used, for example, the distortion becomes complicated. For example, a rectangle includes long and short sides. When it is not perpendicular, it may be a parallelogram. At this time, it is necessary to determine the angle between the plane of the rectangle and the connection line (between the calibration device and the detection terminal) according to the angle between the two adjacent sides of the parallelogram, and then convert and calculate the photographed parallelogram according to the cosine relationship. The length of the object represented by each side, and then calculate the actual distance represented by each graphic element in the pressing direction.

According to an optional technical solution of the present disclosure, the detection terminal 200 includes a communication module 203. The cardiopulmonary resuscitation operation detection system also includes a server 300, a server 300 command center. The detection terminal 200 can connect to the server 300 through the communication module 203 to exchange data.

According to an optional technical solution of the present disclosure, the detection terminal 200 further includes a positioning module 204, such as a GPS module, for positioning the position of the detection terminal 200. Optionally, the detection terminal 200 further includes a Bluetooth module 205 for the Bluetooth connection calibration device 100. Optionally, the detection terminal 200 further includes a voice input module 206 for inputting voice. Optionally, the detection terminal 200 further includes a voice output module 207 for outputting voice. Optionally, the detection terminal 200 further includes a display module 208 for displaying image information.

When the detection terminal 200 or the server 300 determines that some parameters of the cardiopulmonary resuscitation do not meet the requirements, the calibration device 100 or the detection terminal 200 can issue a prompt.

After the detection terminal 200 is connected to the calibration device 100 via Bluetooth, the calibration device 100 and the detection terminal 200 can interact with each other. For example, various parameters detected by the calibration device 100 can be sent to the detection terminal 200. The detection terminal 200 can send various parameters to the server 300, including the location of the detection terminal 200, the detected pressing depth, and so on. The relevant personnel of the command center can guide the rescue work based on the data received by the server 300, such as instructing rescuers to perform cardiopulmonary resuscitation operations. The voice input module 206, the voice output module 207, and the display module 208 of the detection terminal 200 facilitate voice and image communication between rescuers and the command center. Through the detection terminal 200, the command center can also conduct other first aid instructions such as airway opening procedures and artificial respiration.

According to an optional technical solution of the present disclosure, the processing module 202 determines the pressing frequency according to the video image of the calibration device. The compression frequency is determined by the video image of the calibration device, which can support different rescuers to wear different calibration devices for relay rescue, avoiding the Bluetooth connection of different calibration devices to the detection terminal and affecting the rescue process. For example, the detection terminal automatically detects a bracelet with a predetermined pressing action in the field of view (that is, the range of the viewing angle that can be photographed), without the need for a complicated pairing process between the bracelet and the detection terminal. If multiple bracelets are detected at the same time, the movement of the bracelet closest to the specified pressing frequency will be detected first. If multiple bracelets are detected to be reciprocating at a pressing frequency close to the specified frequency, the pressing action parameters of multiple bracelets will be recorded at the same time, and a warning will be issued at the same time, until only one bracelet in the field of view is close to the specified pressing frequency Frequency operation. Through such a setting, multiple rescuers can be allowed to relay, without the need to interrupt the recording process of the detection terminal in the middle, so that the rescue process is smoother.

According to an optional technical solution of the present disclosure, when the detection terminal 200 cannot recognize the calibration device 100, if the calibration device 100 is blocked, the detection terminal 200 considers the target to be lost and issues an alarm. The alarm can be in the form of voice, vibration, or screen flicker of the detection terminal.

The detection terminal 200 may be a smart device such as a mobile phone or an iPad. Taking a mobile phone as an example, the front camera is preferably used as the camera module 201, so that the rescuer can check whether the pressing part and the range of the pressing action are better placed in the shooting area. An acceleration sensor may be provided in the detection terminal 200 to ensure that the placement posture of the detection terminal 200 is kept as vertical as possible.

As shown in Figures 10 to 12, the detection terminal support 400 includes a housing 410. The housing 410 is provided with a groove 411 for fixing the detection terminal 200. When in use, the detection terminal 200 is placed in the groove 411 of the housing 410 , Realize the fixation of the detection terminal 200, and avoid unnecessary movement of the detection terminal 200 during the treatment process.

The detection terminal 200 is provided with a second light source 209 capable of illuminating the light guide plate 420. Taking a mobile phone as an example, the rear camera of the mobile phone can be used as the second light source 209. The light from the second light source 209 is reflected by the light guide plate 420 and then emitted in the form of diffused light. The light emitted from the light guide plate 420 can increase the brightness of the marking member 102. The light guide plate 420 may be connected to the housing 410 through a rotating shaft, and when the light guide plate 420 is not used, it will rotate to the rear side of the housing 410.

According to an optional technical solution of the present disclosure, the detection terminal support 400 further includes a single-lead ECG module 430. The single-lead ECG module 430 is used to monitor the heartbeat. If a person in need of rescue is found, the rescuer can measure the heartbeat of the rescued person through the single-lead ECG module 430 to determine whether cardiopulmonary resuscitation is required. The detection terminal bracket 400 is used to supply power to various components of the detection terminal bracket 400.

Optionally, the detection terminal bracket 400 includes a data line 450 for connecting the detection terminal 200. Through the data line 450, the data interaction between the detection terminal 200 and the detection terminal support 400 is realized. The data cable can be type-c, micro-usb or the data cable of the interface used by the iphone.

According to an optional technical solution of the present disclosure, the detection terminal support 400 includes a foldable leg 440. When the leg 440 is not in use, the leg 440 is folded and folded on the rear side of the housing 410. When the outrigger 440 needs to be used, the outrigger 440 is unfolded, and the outrigger 440 cooperates to form a stable support. If the detection terminal 200 is a mobile phone, when the legs 440 are stowed, the detection terminal support 400 can be used as a mobile phone case.

The leg 440 includes a first folding board 441 and a plurality of second folding boards 442. The number of the first folding plate 441 may be one or more. The shaft of the leg 440 is provided with a damping component, that is, the adopted damping shaft.

When the number of the first folding plate 441 is one, one end of the first folding plate 441 is connected to the bottom end of the housing 410 through the first damping shaft. The plurality of second folding plates 442 are connected to the first folding plate 441 through a second damping shaft. Through the cooperation of the stop structure, the first folding board 441 and the second folding board 442 can be unfolded at a preset angle to form a stable supporting structure.

When the number of the first folding plates 441 is multiple, the multiple first folding plates 441 are sequentially foldably connected by the first damping shaft. The uppermost first folding plate 441 is connected to the bottom end of the housing 410 through a first damping shaft. The plurality of second folding plates 442 are connected to the lowermost first folding plate 441 through a second damping shaft. Through the cooperation of the stop structure, the first folding board 441 and the second folding board 442 can be unfolded at a preset angle to form a stable supporting structure. The first damping shaft and the second damping shaft in this embodiment can use existing models. The legs 440 may also be in other foldable forms.

According to an optional technical solution of the present disclosure, rescuers can instantly monitor the heartbeat and breathing conditions of rescued personnel through the blood oxygen detector. The blood oxygen detector may be a Bluetooth blood oxygen detector, which is connected to the detection terminal 200 or the detection terminal bracket 400 through a Bluetooth connection.

During the treatment process, the detection terminal can also be used to warn the surrounding people. For example, the second light source continuously flashes and emits a flashing light to remind the surrounding people that there is an emergency situation and avoid the surrounding people from interfering with the treatment process. If the detection terminal is a mobile phone, preferably, after the mobile phone starts to record the pressing situation, no other calls can be answered except the call of the command center to avoid interference.

The related control of the detection terminal can be realized through APP. An emergency APP is installed on the detection terminal, and rescuers use the emergency APP to control the corresponding modules of the detection terminal to realize cardiopulmonary resuscitation operation detection.

The use process of the cardiopulmonary resuscitation operation detection system of this embodiment is:

1. People need to be rescued; 2. Unfold the legs of the detection terminal bracket, connect the detection terminal bracket and the detection terminal through the data line, and start the emergency APP; 3. Confirm that the cardiopulmonary resuscitation is needed through the single-lead ECG module or other equipment. 4. Put the calibration device on the rescuer's arm, adjust the position of the detection terminal, and start pressing for first aid; 5. Use the detection terminal to monitor the pressing process to determine whether the relevant parameters such as compression depth and compression frequency meet the requirements. If the requirements are not met, a prompt is output. 6. Upload the parameters of the cardiopulmonary resuscitation operation to the server in real time, or upload the relevant parameters to the server after the treatment is over. When necessary, accept the guidance of the command center through the detection terminal.

The cardiopulmonary resuscitation operation detection method and system of the present disclosure reduces the detection error of the compression depth to less than ±0.3 mm through the cooperation of a calibration device, a detection terminal, a server, a detection terminal bracket, etc., and meets the requirements of cardiopulmonary resuscitation.
