Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and relates to a cardiopulmonary resuscitation (CPR) emergency mat. This invention also relates to a method of using the above-mentioned CPR emergency mat. Background Technology

[0002] A CPR mat is an indispensable auxiliary device in CPR procedures. In critical moments of emergency rescue, it plays multiple important roles. Firstly, its unique design precisely optimizes compression positions, ensuring accurate and effective compressions with each effort. Secondly, it helps maintain an open airway, ensuring unobstructed ventilation. Simultaneously, it effectively disperses the reaction force during compressions, reducing rescuer fatigue and allowing the rescue to continue. Furthermore, its well-designed structure reduces the risk of injury to the patient's sternum, ribs, and other areas, comprehensively enhancing the effectiveness of CPR.

[0003] Currently, most commercially available CPR pads offer limited functionality, primarily providing compression support, which significantly limits their effectiveness in emergency situations. When it comes to the crucial step of simultaneous artificial respiration, the pad often cannot perform this function independently, requiring additional specialized equipment or the assistance of qualified personnel on-site. This, to some extent, impacts the efficiency and convenience of emergency care. Summary of the Invention

[0004] The purpose of this invention is to provide a cardiopulmonary resuscitation (CPR) first aid mat, which solves the problem that the existing technology has a single function, only providing pressure support and cannot be combined with emergency operations.

[0005] Another object of the present invention is to provide a method of using the above-mentioned cardiopulmonary resuscitation first aid mat.

[0006] The technical solution adopted in this invention is a cardiopulmonary resuscitation (CPR) emergency mat, which includes a main body of the emergency mat, a back pad that is slidably connected to the main body of the emergency mat, a rack that is fixedly connected to the inner bottom surface of the main body of the emergency mat, the rack meshing with a gear, one end of the gear being connected to an air cylinder, the other end of the air cylinder being connected to a first air supply pipe and communicating with an air storage box, and the air storage box being connected to a mask through a second air supply pipe.

[0007] The invention is further characterized by:

[0008] A threaded rod is fixedly connected to one end of the gear. The threaded rod is rotatably installed inside the air cylinder. A piston is threadedly connected to the threaded rod, and the piston is slidably connected inside the air cylinder. An inlet pipe and an outlet pipe are fixedly connected to the end of the air cylinder away from the gear. A one-way valve is installed inside both the inlet pipe and the outlet pipe. The outlet pipe is connected to the air storage box through the first air supply pipe. The air cylinder is fixedly connected inside the main body of the emergency pad. A connecting plate is fixedly installed at the bottom of the back pad, and the connecting plate is connected to the inner bottom surface of the main body of the emergency pad via a telescopic rod.

[0009] The mask has a threaded through hole on its side wall and a two-way threaded rod that passes through it. A connecting block is fixedly connected to one end of the two-way threaded rod inside the mask. Two nose clips are also threaded onto the two-way threaded rod. A handle is fixedly connected to one end of the two-way threaded rod outside the mask.

[0010] One end of the emergency pad is fixedly connected to a buttock pad, and the end of the buttock pad connected to the emergency pad is higher than the other end of the buttock pad.

[0011] One end of the emergency pad body is fixedly connected to the head pad, and the end of the head pad connected to the emergency pad body is higher than the other end of the head pad. The gas tank is fixedly connected to the head pad.

[0012] A groove is made in the head pad, and the side wall of the groove is connected to the air bladder.

[0013] Sensors are installed on the back pad, and a display screen and an alarm are installed on the surface of the head pad. The display screen and the alarm are electrically connected to the sensors.

[0014] The emergency mat has a drawer that slides inside one side of its main body.

[0015] The kneeling pad is slidably connected to one side of the main body of the first aid mat.

[0016] Another technical solution adopted in this invention is a method of using a cardiopulmonary resuscitation (CPR) emergency mat. Using any CPR emergency mat, the specific steps are as follows: place the patient on the main body of the emergency mat, place the patient's chest and back on the back pad, cover the patient's face with a mask, and press on the patient's chest.

[0017] The beneficial effects of this invention are: (1) The cardiopulmonary resuscitation (CPR) emergency pad of the present invention combines compression and ventilation functions. When the emergency personnel perform chest compressions on the patient, the back pad moves down and through a series of mechanical transmissions, the air cylinder generates negative pressure to draw in air. After a certain number of compressions, the air is sent into the storage tank and finally delivered to the mask for the patient to breathe. The scientific 30:2 ratio of compression to ventilation is used to coordinate compression and ventilation, eliminating the need for emergency personnel to operate the ventilation equipment, greatly simplifying the emergency procedure and improving emergency efficiency. At the same time, the grooves and elastic air bladders of the head pad can stabilize the patient's head and prevent shaking; the inclined design and anti-slip texture of the hip pad help the patient maintain the correct position and open the airway, providing a guarantee for the effective performance of CPR.

[0018] (2) The sensors installed on the back pad of the cardiopulmonary resuscitation (CPR) first aid mat of the present invention can monitor the compression frequency, compression depth, and rebound degree in real time, and transmit the data to the display screen, allowing first aid personnel to intuitively understand the compression situation and adjust the compression intensity and frequency in a timely manner. When the compression action is not up to standard, the alarm will sound an alarm signal to remind the first aid personnel to correct the operation and ensure that every compression meets the standard, effectively improving the success rate of CPR and giving patients more chances for life safety. In addition, the kneeling pad equipped with the first aid mat can reduce the pressure on the knees of first aid personnel, and the drawer is convenient for storing first aid supplies, further improving the convenience and comfort of first aid.

[0021] The following detailed description is provided in conjunction with specific implementation methods.

[0022] like Figure 1 As shown, the CPR emergency mat includes a main body 1, with a back pad 2 slidably connected to the main body 1. The back pad 2 is used to support the patient's chest and back. The back pad 2 can be slidably adjusted on the main body 1 to adapt to different patients' physical conditions and emergency needs.

[0023] One end of the emergency pad body 1 is fixedly connected to the head pad 15. The end of the head pad 15 connected to the emergency pad body 1 is higher than the other end of the head pad 15, that is, the head pad 15 is at an inclined angle, so that it can better fit the patient's head, improve the patient's comfort when using it, and also facilitate the opening of the airway, creating favorable conditions for cardiopulmonary resuscitation.

[0024] The head cushion 15 is provided with a groove 20, which can confine the patient's head within the groove 20. The groove 20 can fix the patient's head and prevent the patient's head from shaking during the emergency.

[0025] The other end of the main body 1 of the emergency cushion is fixedly connected to a hip pad 22. The end of the hip pad 22 connected to the main body 1 of the emergency cushion is higher than the other end of the hip pad 22, that is, the back pad 2 is higher than the head pad 15 and the hip pad 22. The patient's head is placed on the head pad 15, the patient's chest and back are placed on the back pad 2, and the patient's buttocks are placed on the hip pad 22, so that the chest is naturally lifted, the airway is opened, and cardiopulmonary resuscitation is facilitated.

[0026] The main body 1 of the first aid mat has a drawer 27 that slides inside one side. The drawer 27 can be used to store first aid supplies or tools, making it convenient for first aid personnel to access them at any time, thus improving the convenience and efficiency of first aid.

[0027] Elastic bands can also be installed on both sides of the main body 1 of the emergency mat. The elastic bands are used to fix the patient's body and prevent the patient from moving during the emergency.

[0028] like Figure 2 As shown, the sidewalls of the groove 20 are connected to two elastic inflatable bladders 21 respectively. The patient's head is clamped between the two inflatable bladders 21. The elasticity of the inflatable bladders 21 can be adaptively adjusted according to the shape of the patient's head, improving the patient's head comfort and also better fixing the head.

[0029] The surface of the buttock pad 22 is provided with anti-slip texture, which increases the friction between the buttock pad 22 and the patient's buttocks, preventing the patient from slipping during the emergency and ensuring the stability of the emergency process. Elastic bands are provided on both sides of the main body 1 of the emergency pad. These elastic bands can be used to fix the patient's body and prevent the patient's movement during the emergency from affecting the effectiveness of the emergency.

[0030] A kneeling pad 26 is slidably connected to one side of the main body 1 of the first aid pad. The kneeling pad 26 can be pulled out from the main body 1 of the first aid pad, which makes it convenient for first aiders to kneel down when performing cardiopulmonary resuscitation and reduces pressure on their knees.

[0031] like Figure 3As shown, a sensor 23 is installed on the back pad 2, and a display screen 24 is installed on the surface of the head pad 15. The display screen 24 is electrically connected to the sensor 23. When the patient's chest and back are pressed on the sensor 23, the sensor 23 can monitor the compression frequency, compression depth and rebound degree in real time, and display these data accurately on the display screen 24, so that emergency personnel can understand the compression situation in time and adjust the compression strategy.

[0032] An alarm 25 is installed on the surface of the head cushion 15, and the alarm 25 is electrically connected to the sensor 23. When the compression action is not up to standard, such as compression frequency being too fast or too slow, compression depth being insufficient or excessive, the sensor 23 will immediately trigger the alarm 25 to emit an alarm signal, reminding the emergency personnel to adjust the compression method in time, ensuring the effectiveness and safety of cardiopulmonary resuscitation, and avoiding the impact of improper compression on the emergency response.

[0033] like Figure 4 As shown, a connecting plate 3 is fixedly installed at the bottom of the back pad 2. The connecting plate 3 serves to stabilize the connection. The connecting plate 3 is connected to the inner bottom surface of the emergency pad body 1 via a telescopic rod 29 to enable the back pad 2 to slide up and down. A rack 4 is fixedly connected to the inner bottom surface of the emergency pad body 1. The rack 4 meshes with a gear 5. Through the meshing transmission of the rack 4 and gear 5, the up and down movement of the back pad 2 can be converted into the rotational movement of the gear 5, realizing the transmission and conversion of power. One end of the gear 5 is connected to the air cylinder 7, and the other end of the air cylinder 7 is connected to the first air supply pipe 11 and connected to the air storage tank 12. The air storage tank 12 is connected to the mask 14 via the second air supply pipe 13. An elastic band 16 is fixedly connected to the outer wall of the mask 14. By adjusting the tightness of the elastic band 16, the mask 14 can be ensured to fit tightly against the patient's face to prevent gas leakage and ensure that oxygen can be effectively delivered to the patient's body.

[0034] like Figure 5 As shown, a threaded rod 6 is fixedly connected to one end of gear 5. The threaded rod 6 is rotatably installed inside the air cylinder 7. A piston 8 is threadedly connected to the threaded rod 6, meaning the threaded rod 6 passes through the piston 8, which is slidably connected inside the air cylinder 7. When the threaded rod 6 rotates, it drives the piston 8 to reciprocate inside the air cylinder 7. An inlet pipe 9 and an outlet pipe 10 are fixedly connected to the end of the air cylinder 7 away from gear 5. Both the inlet pipe 9 and the outlet pipe 10 are equipped with one-way valves to ensure that gas can only flow in one direction. The outlet pipe 10 is connected to the gas storage tank 12 through the first gas delivery pipe 11, and the gas storage tank 12 is connected to the mask 14 through the second gas delivery pipe 13, thus forming a complete gas delivery channel to provide the patient with the necessary oxygen support.

[0035] The air cylinder 7 is fixedly installed inside the main body 1 of the first aid mat, ensuring its stability and preventing the gas delivery from being affected by shaking during first aid. The gas storage tank 12 is fixedly installed on the headrest 15 for convenient gas storage and subsequent delivery.

[0036] like Figure 6 As shown, a threaded through hole is provided on the side wall of the mask 14, and a two-way threaded rod 18 passes through the threaded through hole. A connecting block 17 is fixedly connected to one end of the two-way threaded rod 18 inside the mask 14, and a handle 28 is fixedly connected to the other end of the two-way threaded rod 18 outside the mask 14. Two nose clips 19 are also threadedly connected to the two-way threaded rod 18.

[0037] A connecting block is also fixedly connected to the bidirectional threaded rod 18, and the connecting block is located between the inner wall of the mask 14 and the nose clip 19.

[0038] Emergency responders can rotate handle 28, which in turn rotates the bidirectional threaded rod 18, thereby adjusting the two nose clips 19 to move inward or outward simultaneously. This allows for convenient and quick adjustment of the nose clips 19 to accommodate different nasal shapes, improve the sealing and effectiveness of the mask 14, and enhance emergency response efficiency.

[0039] During cardiopulmonary resuscitation (CPR), the patient is placed stably on the main body 1 of the emergency cushion. The patient's head is placed on the headrest 15, which is at an angle and has a groove 20 on its surface. The patient's head is confined within the groove 20. The elastic inflatable bladders 21 on both sides of the groove 20 automatically adjust to the shape of the patient's head, securing the head in the middle and preventing head movement during resuscitation. The patient's chest and back are placed on the backrest 2, and the buttocks are placed on the hip rest 22. The hip rest 22 is tilted towards the tail end of the main body 1, allowing the patient's chest to naturally rise and opening the airway. The anti-slip texture on the surface of the hip rest 22 prevents the patient from slipping, and the elastic bands on both sides of the main body 1 of the emergency cushion further secure the patient's body.

[0040] The emergency responders began chest compressions on the patient, causing the chest to initially move downwards by approximately 5 centimeters. As the patient's chest descended, the back pad 2 experienced pressure from the chest, causing the connecting plate 3, which was fixedly mounted at its bottom, to also move downwards. The downward movement of the connecting plate 3 caused the rack 4, which was fixedly mounted at its bottom, to move downwards simultaneously. Since the rack 4 and the gear 5 meshed with each other, the downward movement of the rack 4 drove the gear 5 to begin rotating.

[0041] Gear 5 is fixedly mounted on threaded rod 6. The rotation of gear 5 drives threaded rod 6 to rotate inside air cylinder 7. Threaded rod 6 is threadedly connected to piston 8, and piston 8 is slidably mounted inside air cylinder 7. When threaded rod 6 rotates, it drives piston 8 to reciprocate inside air cylinder 7.

[0042] When piston 8 moves at one end of gear 5 inside cylinder 7, the internal space of cylinder 7 increases, creating negative pressure. The one-way valve in inlet pipe 9 opens, and outside air enters cylinder 7 through inlet pipe 9. When piston 8 moves towards outlet pipe 10 inside cylinder 7, the internal space of cylinder 7 decreases, and the pressure increases. The one-way valve in outlet pipe 10 opens, and air in cylinder 7 is transported to storage tank 12 through outlet pipe 10 and first air delivery pipe 11.

[0043] In accordance with the 30:2 compression-to-ventilation ratio required in cardiopulmonary resuscitation (CPR), the gas reservoir 12 releases gas once after 15 chest compressions. During gas release, the gas in the gas reservoir 12 is delivered to the mask 14 via the second air supply tube 13, providing necessary ventilation support to the patient and ensuring they receive oxygen.

[0044] The mask 14 is fixedly fitted with elastic straps 16, the tightness of which can be adjusted to ensure a tight fit to the patient's face. Inside the mask 14, a connecting block 17 is rotatably mounted with a bidirectional threaded rod 18. One end of the bidirectional threaded rod 18 passes through the mask 14 and is fixedly fitted with a handle 28. When the rescuer rotates the handle 28, the bidirectional threaded rod 18 rotates, causing two nose clips 19 that are slidably connected inside the mask 14 to move inward or outward simultaneously to adapt to the shape of the patient's nose.

[0045] Sensors 23, mounted on the back pad 2, press against the patient's chest and back to monitor the compression frequency, depth, and rebound rate in real time. The data is then transmitted to a display screen 24 on the headrest 15 for easy monitoring by emergency responders. If the compressions are not performed correctly, sensor 23 triggers an alarm 25 on the headrest 15, alerting emergency responders to adjust the compression method.

[0046] After a compression and breath-blow operation is completed, because the telescopic rod 29 is connected between the connecting plate 3 and the inner bottom surface of the emergency pad body 1, the connecting plate 3 drives the back pad 2 to move upward under the elastic reset action of the telescopic rod 29, returning to the initial position, preparing for the next cardiopulmonary resuscitation operation, and ensuring that the entire emergency process can be carried out continuously, stably and effectively.

[0047] During emergency rescue, rescuers can kneel on the kneeling pad 26 that slides on one side of the emergency mat body 1 to perform the operation, reducing pressure on their knees; the drawer 27 that slides on the other side can be used to store emergency supplies or tools for easy access.
