Description

Cardiopulmonary resuscitation operation detection system, calibration device, detection terminal and detection method

technical field

The present disclosure belongs to the field of detection equipment, and in particular relates to a cardiopulmonary resuscitation operation detection system, a calibration device, a detection terminal and a detection method.

Background technique

Cardiopulmonary arrest is the most urgent clinical situation. Cardiopulmonary resuscitation is widely used in emergency situations of cardiopulmonary arrest. In emergency compression, two parameters are more important, one is the frequency of the compression, and the other is the depth of the compression. The standard proposed by the International Resuscitation Federation and the American Heart Association in 2010 is to ensure that the frequency of chest compressions is > 100 times/minute, and the compression depth should be > 5 cm.

For the detection of the pressing 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 to calculate. Due to the processing accuracy of the acceleration sensor, the changing direction of the pressing, and the interference of gravity, the use of the acceleration sensor to detect the pressing depth has insufficient accuracy. The problem. For example, when the pressing depth is more than 5 cm, the required detection error is less than ±0.5 cm. The accuracy of the current acceleration sensor is often difficult to ensure the required detection accuracy. If a sensor with higher accuracy is used, the cost of the detection device will increase significantly. High-cost detection devices are difficult to popularize, so in actual scenarios, it is difficult to obtain high accuracy for detecting the depth of compression in emergency.

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

As shown in FIG. 1 , an embodiment of the present disclosure provides a system for detecting a cardiopulmonary resuscitation operation. The CPR operation detection system can detect parameters during CPR 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 a CPR operation includes a fixing part 101 and a marking part 102 . During cardiopulmonary resuscitation, the fixing member 101 is used to fix the calibration device 100 to the rescuer's wrist. The marking part 102 is arranged on the fixing part 101 and is formed into a figure with predetermined size parameters, which is used as an optical beacon to facilitate identification in the video image of the calibration device 100 . The marking member 102 includes self-illuminating structures and/or reflective structures.

The graphics and the size of the graphics formed by the marking component 102 are pre-stored in the detection terminal, which is convenient for the detection terminal to perform subsequent processing. In this embodiment, the figure formed by the marking part 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 shape of the marking component 102 may be a rectangle or a square, and the side lengths of the rectangle or square are pre-stored in the detection terminal. The graphics of the marking part 102 may also be in other specific shapes, and only need to have a certain size.

As shown in FIGS. 3 and 4 , the marking member 102 includes a diffuse transmission strip 102 a and a first light source 103 . The diffuse transmission strip 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 arranged 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 passes through the diffuse transmission strip 102 a and emits diffuse light, so that the brightness of the marking component 102 is greater than that of the surrounding environment, which facilitates the identification of the marking component 102 in the video image of the calibration device 100 . The diffused light is not very bright, which ensures accurate focus when photographing the calibration device 100 .

According to an optional technical solution of the present disclosure, there are multiple marking components 102 , which are arranged on the fixing component 101 in sequence, so as to facilitate the identification of the spatial posture of the calibration device 100 . The plurality of 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 to detect the ambient brightness. 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 ambient 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 if 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 strips 102b and/or the fluorescent strips 102c form the pattern on the fixing part of the calibration device. When the power of the calibration device 100 is insufficient and the first light source 103 cannot be turned on, the reflective strips 102b and/or the fluorescent strips 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 member 110 disposed on the fixing member 101 . If the graphic of the marking part 102 is a polygon, the orientation marking part 110 is used to distinguish the direction of the graphic. For example, the graphic of the marking part 102 is a rectangle, and the long side or the short side is set as double bars, so as to distinguish the long side and the short side 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 triaxial acceleration sensor 106 is arranged in the fixing part 101 of the calibration device, and can measure the pressing force during cardiopulmonary resuscitation pressing. If the measured pressing force is too large, the calibration device 100 can issue a prompt to the rescuer to avoid secondary injuries such as fractures. The triaxial 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 apparatus 100 further includes a Bluetooth module 107 . The bluetooth module 107 is used to connect with the detection terminal via bluetooth to perform data interaction. The calibration device 100 further includes a voice output module 108 and/or a vibration module 109 . When it is necessary to prompt the rescuers, the voice output module 108 can output a prompt voice, and the vibration module 109 can generate vibrations to prompt the rescuers.

The calibration device 100 may also be provided with operation buttons, such as up, down, left, right, confirm, and cancel keys, for selecting and confirming/cancelling preset functions or operations in the calibration device 100 .

The calibration device 100 may be a wristband, which is worn on the rescuer's wrist during cardiopulmonary resuscitation. The calibration device 100 may also be a device that can be fixed relative to the 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 moving distance of the bracelet and the moving 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, and is used for photographing the calibration device 100 to obtain a real-time video image of the calibration device 100 . The camera is preferably a high-definition camera, which can ensure the clarity of the scene shooting. 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 photographing process. Typically, the normal of the marking member 102 is substantially 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 component 102 and the video image of the calibration device. The moving distance of the calibration device 100 is the compression depth during cardiopulmonary resuscitation. The compression depth is measured through the cooperation of the calibration device 100 and the detection terminal 200 .

As shown in FIG. 7 , specifically, the size of the marking component 102 is a determined value, and the camera module 201 photographs the calibration device 100 . The detection terminal 200 pre-stores the size parameters of the graphics formed by the marking component 102 . When the calibration device 100 is not moving, the first sub-module 202a of the processing module 202 identifies the image of the marking component 102 from the video image of the calibration device, and determines the first pixel number corresponding to the size of the marking component 102 . According to the size of the marking part 102 and the first number of pixels corresponding to the size of the marking part 102, the actual distance corresponding to the pixels in the video image of the calibration device is determined.

As shown in FIG. 8 , it is assumed that 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 video image of the calibration device that the first number of pixels corresponding to the sides of the square is 100, and the actual distance corresponding to the pixels in the video image of the calibration device is 0.02cm.

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 video image of the calibration device. The second pixel number corresponding to the moving distance of the calibration device is determined according to the upper limit image frame and the lower limit image frame.

As shown in FIG. 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 lower limit image frame of a pressing operation from each image frame of the video image of the calibration device. The number of pixels between the upper limit position and the lower limit position of the marking part 102 in the upper limit image frame and the lower limit image frame is used as the second pixel number corresponding to the moving distance of the calibration device 100 .

When the initial pressing is performed, the image frame in the image when the calibration device 100 is not moved is used as the upper limit image frame of the initial pressing; with the downward movement of the calibration device 100, the pixels corresponding to the marking part 102 in the video image continuously move downward; the processing module When the second sub-module 202b of 202 recognizes that the pixel corresponding to the marking part 102 no longer moves downward, an image frame at this time is regarded as the lower limit image frame of the first pressing. With the upward movement of the calibration device 100, when the second sub-module of the processing module 202 recognizes that the pixel corresponding to the marking part 102 is no longer moved upward, an image frame at this time is regarded as the upper limit image frame of the second pressing; When the apparatus 100 is moved down, the second sub-module 202b of the processing module 202 recognizes that the pixel corresponding to the marking component 102 is no longer moved down, and takes an image frame at this time as the lower limit image frame of the second pressing. In this cycle, 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 pressing. Through the upper limit image frame and the lower limit image frame, the second number of pixels corresponding to the moving distance of the calibration device 100 in each pressing is determined.

The third sub-module 202c of the processing module 202 determines the moving distance of the calibration device according to the actual distance corresponding to the pixels in the video image of the calibration device and the second number of pixels.

For example, in one press, the processing module 202 determines that the second number of pixels corresponding to the moving distance S of the calibration device 100 is 200, the actual distance corresponding to the pixels in the video image of the calibration device is 0.02 cm, and the calculation shows that the moving distance S of the calibration device is 4 cm . Let 4cm be the compression depth for this time.

In an actual scene, 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 shoots the calibration device obliquely. At this time, the processing module 202 can determine which direction the detection terminal 200 shoots the calibration device 100 according to the image deformation amount of the marking component; according to the cosine relationship conversion of the corresponding angle, the processing module 202 determines the actual distance corresponding to the pixel in the video image of the calibration device. This design mainly involves that 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 direction of the connection between the calibration device 100 and the detection terminal 200 . When it is not vertical, the marking part 102 detected by the detection terminal 200 will form a certain distortion. For example, when the marking part is originally circular, when the plane where the marking part of the calibration device is located is not perpendicular to the direction of the connection between the calibration device and the detection terminal, the detected marking part takes on 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 identify the actual size of the marking component according to the graphics actually photographed, for example, the long axis of the ellipse represents the diameter of the circle. In the case of a circle becoming an ellipse, it is also relatively simple, while in the case of eg using rectangles, polygons, etc., the distortion becomes complicated. For example, a rectangle includes long and short sides. When it is not vertical, it may be a parallelogram. At this time, it is necessary to determine the angle between the plane where the rectangle is located 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 calculate the photographed parallelism according to the cosine relationship conversion. The length of the real object represented by each side of the quadrilateral, and then the actual distance represented by each pixel in the pressing direction is calculated.

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 and a command center for the server 300. The detection terminal 200 can be connected to the server 300 through the communication module 203 for data exchange.

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 locating the position of the detection terminal 200 .

After the detection terminal 200 and the calibration device 100 are connected via Bluetooth, the calibration device 100 and the detection terminal 200 can perform data exchange, for example, various parameters detected by the calibration device 100 can be sent to the detection terminal 200 . The detection terminal 200 may send various parameters to the server 300, including the location of the detection terminal 200, the detected pressing depth, and the like. According to the data received by the server 300, the relevant personnel of the command center can guide the rescue work, such as instructing the rescue personnel 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 video communication between rescuers and the command center. Through the detection terminal 200, the command center can also provide other emergency guidance such as airway opening process and artificial respiration.

The detection terminal 200 may be a smart device such as a mobile phone and 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 pressing action range are well placed in the shooting area. An acceleration sensor may be provided in the detection terminal 200 to ensure that the installation posture of the detection terminal 200 is kept as vertical as possible.

The light emitted from the light guide plate 420 can improve the brightness of the marking member 102 . The light guide plate 420 can be connected to the casing 410 through a rotating shaft, and will rotate to the rear side of the casing 410 when the light guide plate 420 is not used.
