Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cardiac compression device for emergency treatment of cardiovascular diseases. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is a basic first aid measure used to maintain life in cases of cardiac arrest. It mainly consists of two parts: chest compressions and artificial respiration. Traditional CPR relies on the rescuer's manual operation to complete these steps, but this method has certain limitations, such as inconsistent pressure, difficulty in maintaining a stable rate, and rescuer fatigue due to prolonged use.

[0003] In existing technologies, such as the MCC-E1 cardiopulmonary resuscitation machine, the product adopts the 3D compression technology (third-generation cardiopulmonary resuscitation) proposed by Professor Dr. Max Weil. It combines the advantages of the heart pump theory and the chest pump principle, and improves the perfusion effect by combining point compression and chest compression.

[0004] The aforementioned product has some shortcomings in practical applications. For example, it focuses on chest compressions; when ventilation is required, an additional, independent ventilation device must be added, increasing the overall cost. Furthermore, medical personnel must manually operate the ventilation device while performing compressions, increasing manpower and potentially causing interruptions in compressions, thus affecting the quality of CPR. Therefore, it is necessary to propose a cardiac compression device for cardiovascular emergency care that utilizes a single power source for both compressions and ventilation. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a cardiac compression device for emergency cardiovascular disease treatment. Through a single-source, multi-drive design of the drive components, the functions of compression, ventilation, and intermittent control are integrated into a single power source. The rotation of the rotating wheel not only drives the compression component but also simultaneously drives the ventilation and intermittent control components, eliminating the need for manual switching or adjustment. This automates emergency procedures through a coordinated operation mode, reducing human error and improving the quality and stability of cardiopulmonary resuscitation.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a cardiac compression device for emergency treatment of cardiovascular diseases, comprising a frame, wherein the frame is provided with a compression component for assisting in cardiac compression, a ventilation component for assisting in ventilation, and an intermittent component for intermittent ventilation.

[0007] The pressing assembly includes a pressing block, a toggle lever, and a rotating wheel. The pressing block is slidably connected to the frame. The toggle lever is hinged to the top of the pressing block, and the end of the toggle lever away from the pressing block is eccentrically hinged to the rotating wheel.

[0008] The frame is equipped with a drive assembly for rotating the rotating wheel; the drive assembly is used to drive the ventilation assembly and the intermittent assembly to operate synchronously, so that the intermittent assembly can assist in intermittent ventilation.

[0009] When the drive component presses the lower block 30 times, the intermittent component operates to drive the ventilation component to ventilate twice continuously.

[0010] The technical principles of the above solution are as follows:

[0011] The drive assembly rotates a rotating wheel at a constant speed around its central axis. The eccentric hinge point of the rotating wheel (connected to the lever) rotates in a circular motion with the wheel. The lever converts this rotational motion into the linear reciprocating motion of the compression block, thus enabling chest compressions. Simultaneously, the ventilation assembly assists with ventilation during compressions. An intermittent assembly drives the ventilation assembly, which is set to deliver air twice into the airway every thirty compressions, achieving a standardized cardiopulmonary resuscitation cycle through synergistic action.

[0012] The above approach has the following beneficial effects:

[0013] 1. This invention utilizes a single drive source to mechanically link multiple components, enabling the chest compression and ventilation process through component connections. When the drive assembly rotates the rotating wheel at a uniform speed, the eccentrically hinged lever converts the rotational motion into the linear reciprocating motion of the compression block, ensuring consistent compression depth and rebound amplitude with each compression. Simultaneously, the intermittent component, through a trigger mechanism, sets a cycle of two consecutive ventilations every thirty compressions. This design automates emergency procedures through a coordinated operational mode, reducing human error and improving the quality and stability of CPR.

[0014] 2. This invention integrates chest compressions, ventilation, and intermittent control functions into a single power source through a multi-drive design for the drive components. The rotation of the rotating wheel not only drives the chest compression components but also simultaneously powers the ventilation and intermittent control components, eliminating the need for manual switching or adjustment. Rescuers only need to activate the drive components, and the device automatically completes the automated process of chest compressions, counting, and ventilation. This design effectively reduces the complexity of first aid procedures, allowing even non-professionals to quickly master the techniques, shortening the emergency response window, and thus further improving emergency response efficiency.

[0015] 3. This invention replaces manual labor with mechanical transmission. The drive component provides continuous and stable power output, ensuring that the compression frequency and depth meet the standards. Simultaneously, the mechanical triggering mechanism of the intermittent component does not rely on electronic sensors, avoiding functional failures due to insufficient power or signal interference. This design allows the device to maintain stable performance during prolonged emergency treatment, effectively extending the duration of high-quality compressions and giving patients a greater chance of survival.

[0016] Furthermore, the drive assembly includes a controller and a rotating component. The rotating component is fixedly connected to the side of the frame away from the lower pressure block. The controller is used to control the rotating component to rotate. The output shaft of the rotating component is coaxially and fixedly connected to the rotating wheel.

[0017] Beneficial effects: The coordinated design of the controller and rotating component enables controllability of the compression process. The controller can adjust the rotation speed of the rotating component in real time according to emergency needs, ensuring that the compression frequency driven by the rotating wheel meets the standards of the cardiopulmonary resuscitation guidelines. The output shaft of the rotating component is coaxially and fixedly connected to the rotating wheel, reducing the power loss and error accumulation of traditional multi-stage transmission, making the compression action more stable and the response more timely, effectively improving the operational accuracy of cardiopulmonary resuscitation and the success rate of emergency treatment.

[0018] Furthermore, the ventilation assembly includes a conveying section fixedly connected to the frame, with a movable plate slidably fitted on the inner wall of the conveying section; a sliding rod is fixedly connected to the top of the movable plate, with one end of the sliding rod extending away from the movable plate to the outside of the conveying section and fixedly connected to the top of the lower pressure block.

[0019] The bottom of the conveying section is connected to an input pipe and an output pipe, both of which are connected to a one-way valve. The one-way valves are located at the connection points between the input pipe and the output pipe and the conveying section. The input pipe is connected to the outside of the conveying section, and the end of the output pipe away from the conveying section is connected to a storage section. The storage section is fixedly connected to the side of the frame near the conveying section, and the side of the storage section away from the frame is connected to a conveying pipe. The end of the conveying pipe away from the storage section is connected to a breathing mask.

[0020] Beneficial effects: Ventilation is directly driven by the compression action, achieving efficient linkage between compression and ventilation. The reciprocating motion of the compression block synchronously drives the movable plate to slide within the delivery section via a sliding rod. During compression, the compression block pushes the movable plate to compress the delivery section, and gas enters the storage section through the output tube; during rebound, the movable plate moves upward to create negative pressure, and outside air is replenished through the input tube. The one-way valve prevents gas backflow, ensuring accurate ventilation direction; the storage section buffers the gas flow, making the tidal volume delivered to the breathing mask more stable. This design requires no additional power source, completing ventilation through mechanical movement, simplifying the device structure while improving the continuity and reliability of emergency operations.

[0021] Furthermore, the intermittent assembly includes a turntable rotatably connected to the frame, and a gate plate rotatably connected to the inner wall of the conveying pipe; a connecting rod is fixedly connected to the gate plate, and a first gear is fixedly connected to the top of the connecting rod extending to the outside of the conveying pipe; a number of locking teeth that mesh with the first gear are fixedly connected at intervals on the turntable; and a transmission assembly for driving the turntable to rotate is provided on the frame.

[0022] Beneficial effects: Precise control of ventilation rhythm is achieved through mechanical linkage; the transmission component drives the turntable to rotate, and the spaced teeth on the turntable periodically mesh with the first gear, driving the gate to rotate via the connecting rod, thereby intermittently opening or closing the delivery tube. The spacing of the teeth corresponds to the number of compressions, ensuring that the ventilation frequency meets CPR standards; the rigid connection of the mechanical transmission avoids delays or signal interference from electronic control, making the ventilation rhythm stable and reliable, effectively improving the standardization and success rate of emergency procedures.

[0023] Furthermore, the transmission assembly includes a second gear and a third gear. The second gear is coaxially and fixedly connected to the turntable, and the second gear is rotatably engaged with the frame. The second gear meshes with the third gear, and the third gear is coaxially and fixedly connected to the output shaft of the rotating component. The diameter of the third gear is smaller than that of the second gear.

[0024] Beneficial effects: The rotational speed is matched through the engagement of the second and third gears, ensuring synchronization between intermittent control and chest compressions. The third gear rotates coaxially with the output shaft of the rotating component, meshing with and driving the second gear to form a reduction transmission structure. This reduces the turntable speed to a specific value that matches the compression frequency, thus corresponding to the emergency rhythm of CPR. The high rigidity and zero-slip characteristics of the second and third gear transmission reduce transmission errors, ensuring accurate timing of ventilation triggering and effectively improving the standardization and reliability of CPR procedures.

[0025] Furthermore, the breathing mask is equipped with an opening assembly for opening the opening. The opening assembly includes support rods that are symmetrically slidably connected to the inner wall of the breathing mask, and each support rod is hinged with a movable rod. A telescopic component is fixedly connected to the outer wall of the breathing mask. A controller is used to control the telescopic component to extend and retract. The output shaft of the telescopic component extends to the inside of the breathing mask and is fixedly connected to a movable seat. The end of the movable rod away from the support rod is hinged to the movable seat.

[0026] Beneficial Effects: The coordinated design of the controller and telescopic components enables automated control of mouth opening, optimizing the efficiency of emergency procedures. The controller adjusts the telescopic components in real time according to ventilation needs, driving the moving seat towards the inner wall of the mask. Through the hinged transmission of the movable rod, the symmetrical support rods slide synchronously to both sides, thus opening the patient's mouth. This process requires no manual intervention, reducing the delays or uneven force issues associated with traditional manual mouth opening and shortening preparation time. Furthermore, the design, linked to the ventilation activation, ensures efficient gas delivery through the oral cavity, effectively improving tidal volume utilization and the success rate of cardiopulmonary resuscitation, while reducing the complexity of emergency procedures.

[0027] Furthermore, the breathing mask also includes a blocking component for covering the nose, the blocking component including a block located at the nose, the block being fixedly connected to the outer wall of an adjacent support rod.

[0028] Beneficial effects: The linkage design of the stop and support rod enables synchronized opening of the mouth and nasal obstruction, improving ventilation efficiency and ease of operation. When the support rod slides to open the patient's mouth, the stop, which is fixedly connected to it, moves towards the nose and positions itself, automatically obstructing the nasal passage. This linkage structure reduces the cumbersome steps of separately adjusting the nasal obstruction required in traditional designs, reducing operation time and the risk of error. The real-time tracking characteristic of the stop ensures that it always conforms to the contour of the nose, effectively reducing gas leakage from the nasal cavity and concentrating gas delivery through the oral cavity during ventilation, thus improving tidal volume utilization.

[0029] Furthermore, a gas sensor is installed at the connection between the delivery tube and the breathing mask. The controller is used to receive the gas signal transmitted by the gas sensor and control the telescopic component to extend and retract based on the gas signal.

[0030] Beneficial effects: The linkage design of gas sensors and controllers enables intelligent synchronous control of ventilation status and mouth opening actions, effectively improving the accuracy and safety of emergency operations. This dynamic adjustment mechanism ensures that the mouth opening action matches the actual ventilation rhythm, guaranteeing efficient gas delivery through the mouth while reducing unnecessary mouth opening time, lowering the risk of patient discomfort, and providing technical support for the standardized and intelligent operation of cardiopulmonary resuscitation.

[0031] Furthermore, an outer shell is fixedly connected to the outer wall of the frame, and an automatic defibrillator is fixedly connected to the outer wall of the outer shell. The controller is used to control the opening and closing of the automatic defibrillator.

[0032] Beneficial Effects: The integrated design of the automated external defibrillator (AED) and chest compression device, along with the controller's linkage mechanism, enhances the continuity and timeliness of the entire cardiovascular emergency process. It reduces the time-consuming steps of separately handling the defibrillator in traditional emergency care. The controller automatically triggers the defibrillator's activation and deactivation based on the compression status, ensuring seamless coordination between defibrillation, chest compressions, and ventilation. This linkage design follows the sequence of CPR compressions, defibrillation, and ventilation, reducing human error and the risk of equipment switching mistakes. It buys crucial time for patients with life-threatening arrhythmias such as ventricular fibrillation, while also reducing the complexity of multi-device operation for rescuers, effectively improving the success rate and standardization of emergency care.

[0033] Furthermore, a pressure sensor and a damper are fixedly connected to the bottom of the lower block; the controller is used to receive the pressure information emitted by the pressure sensor and control the operation of the damper based on the pressure information.

[0034] Beneficial Effects: The coordinated design of the pressure sensor and damper enables intelligent and precise control of the compression process, improving the effectiveness and safety of chest compressions. The pressure sensor collects real-time contact pressure data between the compression block and the patient's chest wall and feeds it back to the controller. When insufficient compression force is detected, the controller controls the damper to reduce resistance, ensuring effective compression depth; if excessive pressure is detected, the damper is driven to increase resistance, limiting excessive compression. Simultaneously, the adaptive adjustment of the damper reduces the rescuer's reliance on experience in compression force, enabling personnel of varying skill levels to perform standardized compressions, providing reliable technical support for the standardized implementation of emergency care.

Detailed Implementation

[0044] The following detailed description illustrates the specific implementation method:

[0045] Example 1:

[0046] As attached Figure 1 As shown: A cardiac compression device for emergency treatment of cardiovascular diseases includes a frame 1, on which a compression component for assisting in cardiac compression, a ventilation component for assisting in ventilation, and an intermittent component for intermittent ventilation are provided.

[0047] The pressing assembly includes a lower pressing block 2, a toggle lever 3, and a rotating wheel 4. The lower pressing block 2 is slidably connected to the frame 1. The toggle lever 3 is hinged to the top of the lower pressing block 2, and the end of the toggle lever 3 away from the lower pressing block 2 is eccentrically hinged to the rotating wheel 4.

[0048] The frame 1 is equipped with a drive assembly for rotating the rotating wheel 4; the drive assembly drives the ventilation assembly and the intermittent assembly to operate synchronously, so that the intermittent assembly assists in intermittent ventilation. When the drive assembly drives the lower block 2 to press 30 times, the intermittent assembly operates to drive the ventilation assembly to ventilate twice continuously.

[0049] The drive assembly includes a controller and a rotating component 5. In this embodiment, the rotating component 5 is a motor. The rotating component 5 is bolted to the side of the frame 1 away from the lower pressure block 2. The controller is used to control the rotating component 5 to rotate. The output shaft of the rotating component 5 is coaxially and fixedly connected to the rotating wheel 4 through a coupling.

[0050] Specifically, when the controller receives a start command (such as an emergency trigger signal), it first sends an electrical signal to the rotating component 5 (motor) to control the motor to start and rotate at a preset speed (in this embodiment, the speed is set to 100-120 r / min, which meets the requirements of CPR compression frequency). Since the motor output shaft is coaxially and fixedly connected to the rotating wheel 4 through a coupling, the rotating wheel 4 can rotate synchronously with the motor output shaft.

[0051] Because the rotating wheel 4 and the actuating lever 3 are eccentrically hinged, when the rotating wheel 4 rotates, the eccentric end of the actuating lever 3 will periodically move closer to or further away from the lower pressure block 2; Figure 2 For example, when the rotating wheel 4 rotates to the point where the eccentric end of the lever 3 moves downward, the lever 3 can push the pressure block 2 to slide downward along the frame 1 (completing the heart compression action); when the rotating wheel 4 continues to rotate to the point where the eccentric end of the lever 3 returns to its original position, the lever 3 pulls the pressure block 2 to slide upward along the frame 1 (completing the reset action after compression).

[0052] The controller can precisely control the rotation frequency (i.e., the compression frequency) of the rotating wheel 4 by adjusting the rotation speed and angle of the motor. During this process, the continuous rotation of the rotating wheel 4 converts the circular motion of the motor into the linear reciprocating motion of the compression block 2 through the lever 3, thereby driving the compression block 2 to complete the continuous and regular chest compression operation.

[0053] Combination Figure 2 and Figure 3 As shown, the ventilation assembly includes a conveying section 6 that is fixedly connected to the frame 1 with screws, and a movable plate 7 that is slidably fitted on the inner side wall of the conveying section 6; a sliding rod 8 is fixedly connected to the top of the movable plate 7 with screws, and the end of the sliding rod 8 away from the movable plate 7 extends to the outside of the conveying section 6 and is fixedly connected to the top of the lower pressure block 2 with screws.

[0054] The bottom of the conveying section 6 is connected to an input pipe 26 and an output pipe 27. Both the input pipe 26 and the output pipe 27 are connected to one-way valves, which are located at the connection points between the input pipe 26 and the output pipe 27 and the conveying section 6. In this embodiment, the one-way valves are used to ensure unidirectional flow of the medium, allowing the medium to flow in through the input pipe 26 and then out through the output pipe 27. The input pipe 26 is connected to the outside of the conveying section 6, and the end of the output pipe 27 away from the conveying section 6 is connected to a storage section 24. In this embodiment, the storage section 24 has a capacity sufficient to store gas for the conveying section 6 to be refilled 30 times. The storage section 24 is fixedly connected to the side of the frame 1 near the conveying section 6 with screws, and the side of the storage section 24 away from the frame 1 is connected to a conveying pipe 9. The end of the conveying pipe 9 away from the storage section 24 is connected to a breathing mask 10. In some preferred embodiments, the input pipe 26 can be connected to an oxygen tank, so that the input pipe 26 provides oxygen to the storage section 24.

[0055] Specifically, when the lever 3 pushes the pressure block 2 to slide downwards along the frame 1 (during CPR), the sliding rod 8, which is fixed to the top of the pressure block 2 by a screw, moves downwards synchronously, causing the movable plate 7 to slide downwards along the inner wall of the conveying section 6. The volume inside the conveying section 6 gradually decreases, and the internal air pressure increases. Since the one-way valve at the connection between the input pipe 26 and the conveying section 6 only allows external gas to flow in, the one-way valve at the connection between the output pipe 27 and the conveying section 6 is opened due to the internal pressure. The gas inside the conveying section 6 is forced into the output pipe 27 and temporarily stored in the storage section 24.

[0056] When the lower pressure block 2 completes one press and returns to its original position (the rotating wheel 4 continues to rotate, and the actuating rod 3 pulls the lower pressure block 2 upward), the sliding rod 8 drives the movable plate 7 to slide upward synchronously, and the volume inside the conveying section 6 gradually increases, while the internal air pressure decreases. At this time, the one-way valve of the input pipe 26 opens, and external air is drawn into the conveying section 6 through the input pipe 26; the one-way valve of the output pipe 27 closes to prevent gas backflow, thus completing the gas storage action during pressing.

[0057] Combination Figure 4As shown, the intermittent assembly includes a turntable 11 rotatably connected to the frame 1, and a gate 12 rotatably connected to the inner wall of the conveying pipe 9. A connecting rod is fixedly connected to the gate 12 with screws, and the top of the connecting rod extends to the outside of the conveying pipe 9 and is fixedly engaged with a first gear 13. The turntable 11 has several teeth 14 integrally formed at intervals that mesh with the first gear 13. The frame 1 is provided with a transmission assembly for driving the turntable 11 to rotate. The transmission assembly includes a second gear 15 and a third gear 16. The second gear 15 is coaxially fixedly connected to the turntable 11 through a coupling, and the second gear 15 is rotatably engaged with the frame 1. The second gear 15 meshes with the third gear 16, and the third gear 16 is coaxially fixedly connected to the output shaft of the rotating component 5 through a coupling. The diameter of the third gear 16 is smaller than that of the second gear 15.

[0058] Specifically, when the rotating component 5 (motor) of the drive assembly is started, its output shaft begins to rotate and drives the coaxially fixed third gear 16 to rotate synchronously. Since the third gear 16 meshes with the second gear 15, and the diameter of the third gear 16 is smaller than that of the second gear 15 (forming a reduction transmission), the second gear 15 will rotate at a lower speed. Because the second gear 15 is coaxially fixed with the turntable 11 through a coupling, the turntable 11 rotates synchronously with the second gear 15 at a low speed.

[0059] The teeth 14 spaced apart along the edge of the turntable 11 rotate with the turntable 11. When a tooth 14 rotates to contact the first gear 13, the tooth 14 pushes the first gear 13 to rotate. The first gear 13 drives the gate 12 to rotate synchronously through the connecting rod, gradually opening the delivery pipe 9 channel. At this time, the gas accumulated in the storage section 24 enters the breathing mask 10 through the delivery pipe 9, completing the ventilation operation. In this embodiment, after the first gear 13 rotates, the subsequent teeth 14 arranged at intervals drive the first gear 13 to rotate again, so that the first gear 13 rotates twice at intervals, thereby allowing the gate 12 to rotate twice continuously, realizing two interval ventilations. After ventilation is completed, the gate 12 rotates back to its original position, closing the delivery pipe 9 channel.

[0060] Because the diameter of the third gear 16 is smaller than that of the second gear 15, for example, in this embodiment, the third gear 16 rotates thirty times, which corresponds to the second gear 15 rotating two times. The rotation frequency of the turntable 11 is synchronized with the number of compressions: when the output shaft of the rotating component 5 drives the compression assembly to complete thirty compressions (corresponding to the third gear 16 rotating thirty times), the second gear 15 drives the turntable 11 to rotate two times. The locking teeth 14 on it and the first gear 13 complete two engagement and disengagement processes, triggering the gate 12 to open twice, realizing the standard CPR operation sequence of two ventilations after thirty compressions, so that the compressions and ventilations are automatically and intermittently coordinated.

[0061] Combination Figure 5 and Figure 6As shown, the breathing mask 10 has an opening assembly for opening the mouth and a blocking assembly for covering the nose. The opening assembly includes support rods 17 symmetrically slidably connected to the inner wall of the breathing mask 10. In this embodiment, the support rods 17 are placed in the mouth before first aid. Each support rod 17 is hinged with a movable rod 18. A telescopic member 19 is fixedly connected to the outer wall of the breathing mask 10 by screws. In this embodiment, the telescopic member 19 is an electric actuator. The controller is used to control the telescopic member 19 to extend and retract. The output shaft of the telescopic member 19 extends into the breathing mask 10 and is fixedly bonded to a movable seat 20. The ends of the movable rods 18 away from the support rods 17 are all hinged to the movable seat 20. The blocking assembly includes a block 21 located at the nose. In this embodiment, the top of the block 21 is set to fit the shape of the nostrils. The block 21 is fixedly connected to the outer wall of the adjacent support rod 17 by screws.

[0062] Specifically, with Figure 6 For example, when the controller triggers the ventilation operation (i.e., the gate 12 opens and the gas in the storage section 24 is about to enter the breathing mask 10), the controller activates the telescopic component 19. When the output shaft of the telescopic component 19 pulls the movable seat 20 towards the inner wall of the breathing mask 10, since the two ends of the movable rod 18 are hinged to the movable seat 20 and the support rod 17 respectively, the movable seat 20 will cause the movable rod 18 to rotate around the hinge point. The hinge end of the movable rod 18 and the support rod 17 generates a force to both sides, pushing the symmetrically arranged support rod 17 to slide up and down along the inner wall of the breathing mask 10. As the support rod 17 expands outward, its end gradually opens the patient's mouth (such as pressing against the upper and lower lips or corners of the mouth), ensuring that the oral cavity is in an open state, providing a channel for the gas to smoothly enter the airway.

[0063] Since the stop block 21 is fixedly connected to the outer wall of the support rod 17 by screws, when the support rod 17 slides to both sides, the stop block 21 moves synchronously towards the nostril along with the support rod 17, fits against the patient's nostril, forms a physical barrier, reduces the possibility of gas leakage from the nasal cavity during ventilation, and thus improves ventilation efficiency.

[0064] When ventilation is complete (gate 12 closes, delivery tube 9 stops supplying air), the controller controls the output shaft of the telescopic component 19 to move in the reverse direction, and the movable seat 20 resets. The movable rod 18 rotates in the reverse direction due to the pull of the movable seat 20, generating a center-pulling force on the support rod 17. The support rod 17 slides along the inner wall of the breathing mask 10 back to its original position, releasing the opening of the mouth. Simultaneously, the stop block 21 moves back with the support rod 17, disengaging from the nasal obstruction position, completing the auxiliary ventilation cycle. This design, through precise control of the telescopic component 19, achieves automated linkage between opening the mouth during ventilation, obstructing the nasal cavity, and resetting during non-ventilation, and coordinates with the 30:2 compression-to-ventilation sequence, further improving the standardization and effectiveness of cardiopulmonary resuscitation (CPR) procedures.

[0065] The specific implementation process is as follows:

[0066] Before performing first aid, accurately align the compression block 2 with the midpoint of the chest. In this embodiment, the device is fixed by means of an external support rod and suction cup. The controller starts the rotating part 5 (motor, speed 100-120r / min). The motor output shaft drives the rotating wheel 4 to rotate synchronously through the coupling. The eccentric structure of the rotating wheel 4 and the actuating rod 3 drives the compression block 2 to make linear reciprocating motion. When the actuating rod 3 is down, it pushes the compression block 2 to press the heart. When the actuating rod 3 is up, it pulls the compression block 2 back to its original position, forming a regular compression.

[0067] The movement of the lower pressure block 2 synchronously drives the sliding rod 8 to move. When pressed, the lower pressure block 2 slides downward and drives the movable plate 7 to compress the conveying part 6 through the sliding rod 8. The gas is pressed into the storage part 24 through the one-way valve of the output pipe 27 for temporary storage. When reset, the movable plate 7 moves upward and causes the conveying part 6 to draw in external air to replenish it. This cycle completes the inflation of the storage part 24.

[0068] After the gas is replenished, the motor output shaft simultaneously drives the third gear 16 to rotate. The second gear 15, which meshes with the small-diameter third gear 16, reduces the speed (sets to rotate the third gear 16 for every thirty rotations, and the second gear 15 for every two rotations), driving the turntable 11 to rotate at a low speed. The retaining teeth 14 on the edge of the turntable 11 mesh with the first gear 13 twice every two rotations (corresponding to thirty presses of the lower pressure block 2), pushing the first gear 13 to drive the gate 12 to rotate through the connecting rod, opening the delivery pipe 9 channel so that the gas in the storage section 24 enters the breathing mask 10, completing the timing synchronization of two breaths after thirty presses.

[0069] During each ventilation, the controller synchronously activates the telescopic component 19 (electric actuator). The output shaft of the telescopic component 19 pulls the movable seat 20 into the mask. The movable rod 18 expands the opening of the two side support rods 17, and at the same time, the stop block 21 fixed to the support rod 17 moves outward to fit the nostril to prevent air leakage. After the ventilation ends, the telescopic component 19 retracts and pushes the movable seat 20 back. The support rods 17 reset and release the expansion. The stop block 21 disengages from the nose, completing a single cycle.

[0070] This embodiment achieves fully automated operation of the entire process of chest compression, gas storage, intermittent ventilation, mouth opening and nose covering by a single power source that links the synchronous movements of chest compression, ventilation, intermittent ventilation and breathing. It conforms to the standard sequence of cardiopulmonary resuscitation and improves the effectiveness of emergency treatment.

[0071] Example 2:

[0072] The difference from the above embodiments is that a gas sensor is provided at the connection between the delivery tube 9 and the breathing mask 10. The controller is used to receive the gas signal transmitted by the gas sensor and control the telescopic member 19 to extend and retract based on the gas signal.

[0073] The specific implementation process is as follows: The linkage design of the gas sensor and controller enables intelligent synchronous control of ventilation status and mouth opening actions, effectively improving the accuracy and safety of emergency operations. The gas sensor collects gas signals in the delivery tube 9 in real time and feeds them back to the controller. When it detects that gas is about to enter the breathing mask 10 through the delivery tube 9, the controller controls the movement of the telescopic component 19, driving the movable seat 20 to move the support rod 17 to open the patient's mouth. If ventilation is detected to have ended, the controller controls the telescopic component 19 to return to its original position, reducing mucosal damage caused by continuous mouth opening. This dynamic adjustment mechanism ensures that the opening action matches the actual ventilation rhythm, guaranteeing efficient gas delivery through the mouth while reducing unnecessary opening time, lowering the risk of patient discomfort, and providing technical support for the standardized and intelligent operation of cardiopulmonary resuscitation.

[0074] Example 3:

[0075] As attached Figure 7 As shown, the difference from the above embodiment is that the outer wall of the frame 1 is also fixedly connected to the outer shell 25 with screws. In this embodiment, several bearing rods are also fixedly connected to the bottom of the outer shell 25. An automatic defibrillator 22 is fixedly connected to the outer wall of the outer shell 25, and the controller is used to control the opening and closing of the automatic defibrillator 22.

[0076] The specific implementation process is as follows: Utilizing the integrated design of the automated external defibrillator (AED) 22 and the chest compression device, along with the controller's linkage mechanism, the continuity and timeliness of the entire cardiovascular emergency process are improved. This reduces the time-consuming steps of separately handling the defibrillator in traditional emergency care. The controller can automatically trigger the defibrillator's activation and deactivation based on the compression status, ensuring seamless coordination between defibrillation, chest compressions, and ventilation. This linkage design follows the sequence of CPR compressions, defibrillation, and ventilation, reducing delays in human judgment and the risk of equipment switching errors. It buys crucial time for patients with life-threatening arrhythmias such as ventricular fibrillation, while also reducing the complexity of multi-device operation for rescuers, effectively improving the success rate and standardization of emergency care.

[0077] Example 4:

[0078] As attached Figure 1 As shown, the difference from the above embodiment is that a pressure sensor and a damper 23 are fixedly bonded to the bottom of the lower pressure block 2; the controller is used to receive the pressure information emitted by the pressure sensor and control the operation of the damper 23 based on the pressure information.

[0079] The specific implementation process is as follows: Intelligent and precise control of the compression process is achieved through the linkage design of the pressure sensor and damper 23, improving the effectiveness and safety of chest compressions. The pressure sensor collects real-time contact pressure data between the compression block 2 and the patient's chest wall and feeds it back to the controller. When insufficient compression force is detected, the controller controls the damper 23 to reduce resistance, ensuring effective compression depth; if excessive pressure is detected, the damper 23 is driven to increase damping, limiting excessive compression. Simultaneously, the adaptive adjustment of the damper 23 reduces the rescuer's reliance on experience in compression force, enabling personnel of different skill levels to perform standardized compressions, providing reliable technical support for the standardized implementation of emergency care.

[0080] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
