Description

Technical Field

[0001] This utility model relates to the field of medical emergency training equipment technology, specifically a real-time error correction training device for chest compression operation. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is an emergency rescue measure for patients suffering from sudden cardiac arrest. Chest compressions are the core component. Standardized compression depth (5-6 cm for adults), frequency (100-120 compressions / minute), location (the junction of the middle and lower thirds of the sternum), vertical direction, and rebound effect directly affect the success rate of resuscitation. Operational errors can lead to rib fractures, organ damage, or ineffective compressions. Chest compression training devices are widely used in rescue training. However, traditional training devices have a single monitoring dimension, mostly monitoring only compression depth and frequency, without simultaneously assessing compression location and sufficient rebound. At the same time, the compression feel of training devices is stiff and fails to simulate the changes in resistance and the "fracture sensation" during real chest compressions. Utility Model Content

[0003] The purpose of this invention is to provide a real-time error correction training device for chest compressions, which has the advantage of providing prompts to trainees through voice broadcast while training them, thereby improving the training effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a real-time error correction training device for chest compressions, comprising a base plate, a central controller fixedly mounted on the left end of the top of the base plate, a guide column fixedly mounted on the middle end of the top of the base plate, a guide cylinder slidably connected to the upper end of the guide column, a laser displacement sensor fixedly mounted on the upper end of the inner cavity of the guide cylinder, a support frame fixedly mounted on the upper end of the outer surface of the guide cylinder, a support plate fixedly mounted on the bottom of the support frame, a variable pitch spring fixedly mounted between the bottom of the support plate and the top of the base plate, a thoracic simulation model fixedly mounted on the top of the support frame, a speaker fixedly mounted on the right end of the thoracic simulation model, a mounting hole provided in the middle of the thoracic simulation model, and a pressure sensor fixedly mounted on the surface of the mounting hole.

[0005] As a preferred embodiment, a fixing frame is fixedly installed at the top right end of the base plate, a guide rod is fixedly installed at the upper end of the fixing frame, and guide grooves are opened at the right ends of both sides of the support frame, with the surface of the guide rod slidably connected to the surface of the guide groove.

[0006] As a preferred embodiment, the number of variable pitch springs is three.

[0007] As a preferred embodiment, a pressing protrusion is fixedly installed on the top of the pressure sensor.

[0008] As a preferred embodiment, the number of mounting holes and pressure sensors are both five, and they are arranged in a cross shape.

[0009] As a preferred embodiment, the output terminals of the pressure sensor and the laser displacement sensor are electrically connected to the input terminal of the central controller, and the output terminal of the central controller is electrically connected to the input terminal of the speaker.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention involves a trainee pressing their hands onto the central area of ​​a chest cavity simulation model, with their palms covering five pressure sensors. Simultaneously, the sensors collect pressure distribution data in real time, transmitting it to a central controller for processing and analysis. If the pressure distribution is uneven and exceeds a threshold, the central controller activates a loudspeaker to issue a voice alert indicating uneven pressure, allowing the trainee to correct their actions promptly. During the compression of the chest cavity simulation model, the support frame and plate move downwards, compressing a variable-pitch spring. The increasing resistance during compression effectively simulates the feeling of pressing on a real chest cavity. Furthermore, the guide cylinder and guide column design ensures proper positioning of the chest cavity simulation model. The axial guidance system prevents the chest cavity simulation model and support frame from shifting, ensuring stable chest compression training. A laser displacement sensor synchronously records the depth of each compression from the chest cavity simulation model, support frame, and guide cylinder, transmitting this data to the central controller for processing and analysis. The central controller then judges and records the compression depth, frequency, and rebound of the chest cavity simulation model based on the depth changes during each compression. When the compression depth exceeds a threshold, the central controller activates the speaker to produce a "click" electronic fracture sound effect, allowing trainees to correct their movements promptly. This coordinated system effectively trains trainees in chest compressions, significantly improving the training outcome. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] The components in this application, such as the base plate 1, central controller 2, variable pitch spring 3, support plate 4, fixing frame 5, support frame 6, thoracic simulation model 7, speaker 8, mounting hole 9, pressure sensor 10, pressing convex cover 11, guide rod 12, guide groove 13, guide cylinder 14, laser displacement sensor 15, and guide column 16, are all general standard parts or components known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0019] Example 1:

[0020] Please see Figures 1-3 As shown, this utility model provides a real-time error correction training device for chest compression operation, including a base plate 1. A central controller 2 is fixedly installed on the left end of the top of the base plate 1. A guide column 16 is fixedly installed on the middle end of the top of the base plate 1. A guide cylinder 14 is slidably connected to the upper end of the guide column 16. A laser displacement sensor 15 is fixedly installed on the upper end of the inner cavity of the guide cylinder 14. A support frame 6 is fixedly installed on the upper end of the outer surface of the guide cylinder 14. A support plate 4 is fixedly installed on the bottom of the support frame 6. A variable pitch spring 3 is fixedly installed between the bottom of the support plate 4 and the top of the base plate 1. A thoracic simulation model 7 is fixedly installed on the top of the support frame 6. A speaker 8 is fixedly installed on the right end of the thoracic simulation model 7. A mounting hole 9 is provided in the middle of the thoracic simulation model 7. A pressure sensor 10 is fixedly installed on the surface of the mounting hole 9.

[0021] In this technical solution, during training, the trainee presses both hands onto the central area of ​​the chest cavity simulation model 7, with the heel of their palm covering five sets of pressure sensors 10. Simultaneously, the pressure sensors 10 at these five points collect pressure distribution data in real time and transmit it synchronously to the central controller 2 for processing and analysis. When the point of maximum pressure deviates from the central pressing point, the central controller 2 controls the speaker 8 to provide voice prompts indicating incorrect pressing position ("too high / too low / too left / too right"), allowing the trainee to correct their movements promptly. During the pressing of the chest cavity simulation model 7, the support frame 6 and support plate 4 move downwards, compressing the variable pitch spring 3. As the resistance generated by the variable pitch spring 3 gradually increases during compression, it effectively simulates the feeling of pressing a real chest cavity. Simultaneously, through the design of the guide cylinder 14 and guide column 16... The device is designed to axially guide the displacement of the thoracic simulation model 7 and the support frame 6, preventing them from shifting and ensuring stable chest compression training. With the help of the laser displacement sensor 15, it can simultaneously record the depth of each compression from the thoracic simulation model 7, the support frame 6, and the guide cylinder 14, transmitting this data to the central controller 2 for processing and analysis. Simultaneously, the central controller 2 can judge and record the compression depth, frequency, and rebound of the thoracic simulation model 7 based on the depth changes during each reciprocating compression. When the compression depth exceeds a threshold, the central controller 2 can control the speaker 8 to produce a "click" electronic fracture sound effect, allowing the trainee to correct their movements promptly. Through this coordinated action, the device effectively trains trainees in chest compressions, significantly improving the training outcome.

[0022] It should be noted that the pitch of the variable pitch spring 3 decreases from top to bottom.

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, a fixed frame 5 is fixedly installed on the right end of the top of the base plate 1, and a guide rod 12 is fixedly installed on the upper end of the fixed frame 5. Guide grooves 13 are opened on the right ends of both sides of the support frame 6. The surface of the guide rod 12 is slidably connected to the surface of the guide groove 13. There are three variable pitch springs 3. A pressing protrusion 11 is fixedly installed on the top of the pressure sensor 10. There are five mounting holes 9 and five pressure sensors 10, which are arranged in a cross shape. The output end of the pressure sensor 10 and the output end of the laser displacement sensor 15 are electrically connected to the input end of the central controller 2. The output end of the central controller 2 is electrically connected to the input end of the speaker 8.

[0025] In this technical solution, the fixed frame 5, guide rod 12 and guide groove 13 are used to guide the support frame 6 and prevent the support frame 6 from rotating or shifting during movement. The setting of the pressing convex cover 11 improves the decorative effect of the top of the pressure sensor 10 and makes it easier for personnel to press the pressure sensor 10 accurately.
