Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency medical equipment technology, and in particular to a cardiopulmonary resuscitation (CPR) emergency mat. Background Technology
[0002] A CPR pad is typically a flat surface made of hard plastic or similar material that supports the heart during CPR. The essence of chest compressions is to compress the sternum, squeezing the heart between the sternum and spine, thereby pumping blood. This requires a firm pad to provide support for the patient's back, creating an effective reaction force. Pressing on a stable, hard surface allows the rescuer's force to be more efficiently converted into compression of the heart.
[0003] Traditional CPR mats are mostly simple flat structures, requiring rescuers to rely solely on visual inspection and intuition to place their hands. The accuracy of positioning depends entirely on personal experience, making it prone to positional deviations. During compressions, due to sweating, fatigue, or the patient's chest movements, the hands can easily slip, and the rescuer cannot detect or accurately judge the degree of deviation. This causes the compression point to gradually deviate from the correct position, increasing the risk of complications such as rib fractures and xiphoid process fractures. Traditional CPR mats are only passive support tools and cannot detect in real time whether the hands have deviated from the correct position or whether the compression pressure is correct, affecting the success rate of resuscitation. Therefore, a new type of CPR emergency mat is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that rescuers can only rely on visual inspection and intuition to place their hands, and the accuracy of positioning depends entirely on personal experience, which makes it easy for positional deviations to occur. During compressions, due to sweating, fatigue, or the rise and fall of the patient's chest, the hands are prone to slipping, and the rescuer cannot detect or accurately judge the degree of deviation, causing the compression point to gradually deviate from the correct position, increasing the risk of complications such as rib fractures and xiphoid process fractures. Traditional cardiopulmonary resuscitation mats are only passive support tools and cannot detect in real time whether the hands have deviated from the correct position or whether the compression pressure is correct. Therefore, this invention proposes a cardiopulmonary resuscitation emergency mat.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cardiopulmonary resuscitation (CPR) emergency mat includes a mat body for placement under the patient's back to provide support. The upper part of the mat body is symmetrically connected to movable rods, and both ends of the movable rods are equipped with positioning lights. This effectively avoids serious complications such as rib fractures, xiphoid process fractures, and liver and spleen damage caused by positioning deviations. The visual reference of the positioning lines is maintained throughout the entire compression process, allowing the rescuer to check whether their hand has deviated using peripheral vision, further reducing the risk of hand slippage during compressions. The mat body is equipped with a feedback system, which includes: A multi-dimensional sensor array module is integrated inside the pad in the area corresponding to chest compressions, and is used to collect multiple compression quality parameters in real time during manual compressions by the rescuer. A control processing module is located inside the pad and connected to the multi-dimensional sensor array. It is used to receive and process the collected data and generate corresponding control commands based on preset first aid guide thresholds. A multimodal feedback module is disposed on the pad and electrically connected to the multidimensional sensor array module. It is used to provide real-time operation feedback and guidance information to the rescuer in two different sensing modes based on the collected multiple compression quality parameters, so as to realize real-time monitoring and active guidance of compression quality.
[0006] The above technical solution further includes: The multidimensional sensing array specifically includes: a multi-point thin-film pressure sensor for detecting the magnitude and distribution of manual pressing force, and a triaxial accelerometer for real-time monitoring of pressing depth, pressing frequency, and chest wall rebound speed and acceleration.
[0007] The control processing module calibrates the detection accuracy of manual pressing depth by fusing data from the multi-point thin-film pressure sensor and the triaxial accelerometer, and analyzes the position of the pressure center point in real time during each pressing process. When the pressure center point deviates, the multimodal feedback module is triggered to issue a position offset warning.
[0008] The multimodal feedback module specifically includes an LED light strip indicator unit for visually displaying whether the manual compression depth has been met in different colors and flashing modes. The LED light strip indicator unit is embedded at the edge of the pad so that the rescuer can observe it without taking their eyes off the pad during the compression process.
[0009] The multimodal feedback module specifically includes a vibration feedback unit that provides tactile warnings to the rescuer through vibrations of different frequencies and intensities when the rhythm of manual compression is incorrect or the compression position is off. The vibration feedback unit is located on the pad below the area where the rescuer's palm is pressing. The vibration feedback unit uses a multidimensional vibration coding method to transmit different information to the rescuer, including: continuous short vibrations indicate that the compression depth is up to standard and the rhythm is correct; continuous long vibrations indicate that the compression depth is too shallow or too deep; intermittent vibrations indicate that the compression position is off; a single strong vibration indicates insufficient chest wall rebound; and two strong vibrations indicate that the compression frequency exceeds the preset range.
[0010] The multimodal feedback module specifically includes a voice synthesis prompt unit for real-time broadcasting instructions generated by the control processing module, wherein the voice synthesis prompt unit provides auditory guidance while the rescuer is focused on manual compression without being distracted.
[0011] The multimodal feedback module also includes an environmental sensing unit, which is used to detect the light intensity and noise level of the current environment. The control processing module automatically adjusts the main feedback mode of the multimodal feedback module according to the detection results of the environmental sensing unit, including increasing the brightness of the LED light strip and reducing the voice volume under low light conditions, and increasing the vibration intensity and switching the LED light strip to a high-frequency flashing mode in noisy environments.
[0012] The upper part of the pad is symmetrically provided with sliding grooves, and a sliding block is slidably provided on the inner side of the sliding groove. The movable rod is rotatably connected to the side of the sliding block. The sliding positioning light can be moved along the sliding groove through the sliding block.
[0013] A first magnet is installed on the inner side of the sliding block, and a second magnet is installed at the end of the movable rod. The first magnet is positioned on the movement trajectory of the second magnet, and the second magnet attracts the first magnet together, fixing the sliding block and the movable rod together.
[0014] The present invention has the following beneficial effects: 1. In this invention, the positioning line illuminated by the positioning light provides the rescuer with an intuitive and continuous visual reference, ensuring that the compression position falls on the lower part of the sternum. This effectively avoids serious complications such as rib fractures, xiphoid process fractures, and liver and spleen damage caused by positional deviation. The visual reference function of the positioning line runs through the entire compression process, and the rescuer can check whether the palm has deviated at any time through peripheral vision, further reducing the risk of hand slippage during compression.
[0015] 2. In this invention, by setting up a detection system, real-time monitoring and active guidance of the pressing quality can be realized. When the user makes a mistake in the rhythm of manual pressing or the pressing position deviates, the multimodal feedback module sends a tactile warning to the rescuer through vibrations of different frequencies and intensities. Each time a deviation occurs during the pressing process, the multimodal feedback module is triggered to issue a position deviation warning. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 like Figure 1 - Figure 3 As shown, the present invention proposes a cardiopulmonary resuscitation (CPR) emergency mat, comprising a mat body 1, which is placed under the patient's back to provide support. The upper part of the mat body 1 is symmetrically connected to movable rods 5, and the ends of the two movable rods 5 are jointly equipped with positioning lights 7. This effectively avoids serious complications such as rib fractures, xiphoid process fractures, and liver and spleen damage caused by positional deviation. The visual reference function of the positioning line is maintained throughout the entire compression process, allowing the rescuer to check whether the palm has deviated at any time using peripheral vision, further reducing the risk of hand slippage during compression. The upper part of the pad 1 is symmetrically provided with sliding grooves 2, and a sliding block 3 is slidably provided on the inner side of the sliding groove 2. The movable rod 5 is rotatably connected to the side of the sliding block 3, and the positioning light 7 is slidable, so that the positioning light 7 moves along the sliding block 2 through the sliding block 3.
[0020] A first magnet 4 is installed on the inner side of the sliding block 3, and a second magnet 6 is installed at the end of the movable rod 5. The first magnet 4 is located on the movement trajectory of the second magnet 6, and the second magnet 6 is attracted to the first magnet 4 and fixes the sliding block 3 and the movable rod 5 together.
[0021] In this embodiment, when the rescuer needs to perform CPR, the patient is placed on the pad 1, and then the two movable rods 5 are rotated to make the second magnet 6 and the first magnet 4 attract each other. At the same time, the sliding block 3 and the movable rods 5 are fixed together. At this time, the two movable rods 5 are perpendicular to the pad 1, and the positioning light 7 is parallel to the pad 1. Then the positioning light 7 is slid, so that the positioning light 7 moves along the sliding groove 2 through the sliding block 3. The positioning line illuminated by the positioning light 7 is completely superimposed on the line connecting the patient's two nipples. The correct position for adult chest compressions is "the lower part of the sternum, the midpoint of the line connecting the two nipples". Aligning with the line connecting the nipples indirectly determines the lateral coordinates of the compression point. The positioning line provides the rescuer with a clear visual reference, eliminating the need to rely on feeling and reducing complications such as rib fractures and xiphoid process fractures caused by positional deviations.
[0022] Example 2 like Figure 1 - Figure 3 As shown, based on Embodiment 1, a feedback system is provided on the pad 1, and the feedback system includes: A multi-dimensional sensor array module is integrated inside the pad 1 in the area corresponding to chest compressions. It is used to collect multiple compression quality parameters in real time during the rescuer's manual compression process. The control processing module is located inside the pad 1 and is connected to the multi-dimensional sensor array and multi-modal feedback module. It is used to receive and process the collected data and generate corresponding control commands based on the preset first aid guide threshold. A multimodal feedback module is installed on the pad 1 and electrically connected to the multidimensional sensor array module. It is used to provide real-time operation feedback and guidance information to the rescuer in two different sensing modes based on the collected multiple compression quality parameters, so as to realize real-time monitoring and active guidance of compression quality.
[0023] The multidimensional sensor array specifically includes: a multi-point thin-film pressure sensor for detecting the magnitude and distribution of manual compression force, and a triaxial accelerometer for real-time monitoring of compression depth, compression frequency, and chest wall rebound speed and acceleration.
[0024] The control processing module integrates data from a multi-point thin-film pressure sensor and a triaxial accelerometer to correct the detection accuracy of manual pressing depth and analyzes the position of the pressure center point in real time during each pressing process. When the pressure center point deviates, the multimodal feedback module is triggered to issue a position offset warning.
[0025] The multimodal feedback module specifically includes an LED light strip indicator unit that visually displays whether the manual compression depth has been met using different colors and flashing modes. The LED light strip indicator unit is embedded at the edge of the pad 1 so that the rescuer can observe it without taking their eyes off the mat during the compression process.
[0026] The multimodal feedback module specifically includes a vibration feedback unit that provides tactile warnings to the rescuer through vibrations of different frequencies and intensities when the rhythm of manual compression is incorrect or the compression position is off. The vibration feedback unit is located on the pad 1 below the area where the rescuer's palm is pressing. The vibration feedback unit uses a multidimensional vibration coding method to transmit different information to the rescuer, including: continuous short vibrations indicate that the compression depth is up to standard and the rhythm is correct; continuous long vibrations indicate that the compression depth is too shallow or too deep; intermittent vibrations indicate that the compression position is off; a single strong vibration indicates insufficient chest wall rebound; and two strong vibrations indicate that the compression frequency exceeds the preset range.
[0027] The multimodal feedback module specifically includes a voice synthesis prompt unit that broadcasts instructions generated by the control processing module in real time, providing auditory guidance while the rescuer focuses on manual chest compressions without being distracted.
[0028] The multimodal feedback module also includes an environmental sensing unit, which is used to detect the light intensity and noise level of the current environment. The control processing module automatically adjusts the main feedback mode of the multimodal feedback module according to the detection results of the environmental sensing unit, including increasing the brightness of the LED light strip and reducing the voice volume under low light conditions, and increasing the vibration intensity and switching the LED light strip to a high-frequency flashing mode in noisy environments.
[0029] In this embodiment, during cardiac resuscitation, a multi-dimensional sensor array module collects multiple compression quality parameters in real time during manual chest compressions. A control processing module then processes these parameters, analyzing the user's compression position and pressure. Based on preset first aid guide thresholds, corresponding control commands are generated. Finally, a multi-modal feedback module provides real-time operational feedback and guidance to the rescuer using two different sensing methods. When the user makes a mistake in the rhythm of manual compressions or deviates from the compression position, the multi-modal feedback module issues tactile warnings through vibrations of different frequencies and intensities. Each time a deviation occurs during compressions, the multi-modal feedback module issues a position deviation warning.
[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
