Description

Technical Field

[0001] This utility model belongs to the field of medical emergency technology, and specifically relates to an emergency training mat. Background Technology

[0002] In my country, approximately 540,000 people suffer cardiac arrest each year, averaging about one case per minute. If high-quality CPR is administered within one minute of cardiac arrest, the survival rate can reach 90%. Therefore, early, high-quality CPR is crucial for improving the survival rate of those rescued. Traditional first aid training methods often lack effective feedback mechanisms, making it difficult for trainees to accurately assess whether their procedures are up to standard, such as the pressure and frequency of chest compressions. This can lead to improper execution during practice, affecting the effectiveness of first aid. Furthermore, existing training mats are typically conventional yoga mats, and prolonged kneeling exercises can cause knee pain. Utility Model Content

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a first aid training mat.

[0004] This utility model provides a first aid training mat, including a training mat body and a control box disposed at the end of the training mat body, wherein the control box is detachably connected to the training mat body; the training mat body includes an anti-slip fixing layer, a support layer and a buffer layer connected in sequence from bottom to top, and a cardiac resuscitation area is printed on the buffer layer for placing a first aid mannequin.

[0005] The support layer is provided with an installation groove and a wiring groove. A flexible strain gauge is installed in the installation groove. The flexible strain gauge is connected to the control box through a shielded twisted pair cable. The shielded twisted pair cable is laid inside the wiring groove.

[0006] The top of the control box is equipped with a buzzer, a first indicator light, and a second indicator light. Inside the control box are a power supply and a controller. The power supply is electrically connected to the flexible strain gauge, the buzzer, the first indicator light, the second indicator light, and the controller. The controller is signal-connected to the flexible strain gauge, the buzzer, the first indicator light, and the second indicator light.

[0007] A further embodiment is that the buffer layer comprises memory foam and non-woven fabric, the memory foam and non-woven fabric are bonded together, and a polyurethane coating is also applied to the upper surface of the non-woven fabric.

[0008] A further embodiment is that the mounting slots are provided in three parts, arranged in a triangular matrix.

[0009] A further embodiment involves having three sets of mounting holes on the buffer layer, with copper-based contacts installed within the mounting holes, and the shielded twisted-pair cable passing through the mounting holes and connecting to the copper-based contacts.

[0010] A further solution is to provide a spring pin adapted to the copper-based contact at the bottom of the control box for connecting the copper-based contact;

[0011] The power supply and controller are respectively connected to the spring pin.

[0012] A further embodiment is that the control box and the buffer layer are bonded together with Velcro.

[0013] A further embodiment is that the control box is also equipped with an analog-to-digital converter module, which is electrically connected to the power supply and the spring pin respectively, and the analog-to-digital converter module is connected to the controller via an IC bus.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention effectively solves the problem of lack of quantitative guidance in traditional first aid training by integrating a flexible strain gauge and a control box into the training mat body. It can monitor the pressure and frequency in real time and provide intuitive feedback through a buzzer and indicator light to help trainees master the standard movements. The training mat body adopts a layered structure to improve the comfort of the kneeling position.

[0016] This invention features a detachable connection between the control box and the training mat body, allowing the control box to be disassembled independently for easy maintenance or replacement of internal electronic components without requiring a complete replacement. Shielded twisted-pair cables are routed within the mounting and wiring slots of the support layer, minimizing external interference and ensuring the signal transmission accuracy of the flexible strain gauges. The control box is integrated into the end of the training mat, not affecting the operating space in the cardiac resuscitation area, while maintaining an overall lightweight design.

[0017] The cushioning layer of this invention is made of memory foam bonded to non-woven fabric and coated with a polyurethane coating, which improves the user experience during training. The non-woven fabric enhances the tear resistance of the cushioning layer, preventing delamination after long-term use, while the polyurethane coating effectively prevents sweat and liquid penetration, extending the lifespan of the cushioning layer.

[0018] The copper-based contacts of the buffer layer of this invention are combined with shielded twisted-pair cables, which can complete the electrical connection without plugging and unplugging the cables. The elastic design of the spring pin can compensate for the slight misalignment between the control box and the training pad, ensuring reliable contact. Attached Figure Description

[0025] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0026] like Figure 1-4 As shown, this utility model provides a first aid training mat, including a training mat body 1 and a control box 3 disposed at the end of the training mat body 1. The control box 3 is detachably connected to the training mat body 1. The training mat body 1 includes an anti-slip fixing layer 4, a support layer 5, and a buffer layer 6 connected sequentially from bottom to top. A cardiopulmonary resuscitation area 2 is printed on the buffer layer 6 for placing a first aid mannequin. The anti-slip fixing layer 4 is made of 8mm thick nitrile rubber, and the support layer 5 is made of 10mm thick high-density polyethylene board. Mounting grooves 12 and wiring grooves 14 are formed on the support layer 5. Three mounting grooves 12 are provided, arranged in a triangular matrix, and the positions of the mounting grooves 12 are adapted to the positions of the cardiopulmonary resuscitation area 2, so that after the first aid mannequin is placed, the mounting grooves 12 are located directly below the chest cavity of the first aid mannequin. This layout allows for more comprehensive and accurate detection of chest compressions. Flexible strain gauges 13 of model FSG15N1A with a wire diameter of 0.5mm are installed in the mounting grooves 12. 2The shielded twisted-pair cable is laid inside the wiring trough 14, and one end is reliably connected to the flexible strain gauge 13. The control box 3 and the training pad body 1 are detachably connected for easy maintenance and replacement. Specifically, in this embodiment, Velcro is used for bonding. A buzzer 11, a first indicator light 9, and a second indicator light 10 are installed on the top of the control box 3. A power supply 15 and a controller 16 are installed inside. The power supply provides stable power support for the flexible strain gauge 13, the buzzer 11, the first indicator light 9, the second indicator light 10, and the controller 16. The controller 16 uses an STM32F103C8T6 microcontroller, which features high performance and low power consumption, and can process data quickly and accurately. The controller 16 is connected to the flexible strain gauge 13, the buzzer 11, the first indicator light 9, and the second indicator light 10 via signal lines to control each component and receive and process data.

[0027] In this embodiment, the cushioning layer 6 is made of 10mm thick slow-rebound memory foam and 0.5mm thick non-woven fabric 7, which are bonded together using environmentally friendly adhesive. Then, a 0.1mm thick polyurethane coating 8 is uniformly coated on the upper surface of the non-woven fabric 7. The slow-rebound memory foam provides good cushioning, reducing the discomfort of knee pressure when kneeling, while the polyurethane coating 8 enhances the wear resistance and water resistance of the cushioning layer 6, extending the service life of the training mat.

[0028] Three sets of mounting holes are drilled on the buffer layer 6 using a drilling machine. The size and position of the mounting holes are adapted to the shielded twisted pair cable and the copper-based contacts. After passing one end of the shielded twisted pair cable through the mounting hole, it is firmly connected to the copper-based contact in the mounting hole by welding to ensure accurate transmission of the signal detected by the flexible strain gauge 13. A spring pin is installed at the bottom of the control box 3, which is adapted to the copper-based contact on the buffer layer 6. During installation, ensure that the spring pin and the copper-based contact can be precisely aligned. The power supply 15 and the controller 16 are connected to the spring pin by wires, using welding or crimping to ensure reliable connection. When the control box 3 is connected to the buffer layer 6, the spring pin and the copper-based contact are in close contact, achieving electrical connection, thereby enabling the control box 3 to receive the signal transmitted by the flexible strain gauge 13 and control the various components.

[0029] Continue to refer to Figure 4An ADS1115 analog-to-digital converter module 17 is installed inside the control box 3. A power supply 15 is electrically connected to the converter module 17 and the spring pin via wires to provide power to the converter module 17. The converter module 17 is connected to the controller 16 via an I2C bus. The converter module 17 converts the analog signal transmitted from the flexible strain gauge 13 into a digital signal for processing and analysis by the controller 16. Through the I2C bus, the digital signal can be transmitted quickly and accurately to the controller 16, thereby enabling real-time monitoring and feedback of the pressing situation.

[0030] In use, the emergency mannequin is placed on the CPR zone 2 of the buffer layer 6. The trainee performs chest compressions. The flexible strain gauge 13 detects the strain signal generated by the compression and transmits this analog signal to the analog-to-digital converter 17 via shielded twisted-pair cable, copper-based contacts, and spring pins. The analog-to-digital converter 17 converts the analog signal into a digital signal and then transmits it to the controller 16 via the I2C bus. The controller 16 determines whether the compression force and frequency meet the standards based on the received digital signal. If both the compression force and frequency meet the standards, the first indicator light 9 illuminates; if the compression force or frequency does not meet the standards, the second indicator light 10 illuminates, and the buzzer 11 sounds an alarm to remind the trainee to adjust the operation. Specifically, a warning threshold is preset in the controller 16 to achieve the warning. For example, if the compression frequency is 100-120 compressions / minute and the compression depth is 5-6 cm for adults and about 5 cm for children, the first indicator light 9 will illuminate. When the compression frequency is less than or more than 100-120 times / minute, and the compression depth is 5-6cm for adults and approximately 5cm for children, the second indicator light 10 will illuminate and the buzzer alarm will sound. Conversely, when the compression frequency is 100-120 times / minute, and the compression depth is less than or more than 5-6cm for adults and less than or more than 5cm for children, the second indicator light 10 will illuminate and the buzzer alarm will sound. It is important to note that the compression depth is positively correlated with the pressure exerted on the flexible strain gauge 13; that is, within a certain range, the greater the pressure on the flexible strain gauge 13, the deeper the compression. Therefore, a warning can be issued by setting a compression depth threshold.
