A cardiac resuscitation training device

Abstract

This invention provides a cardiac resuscitation training device, relating to the field of medical training equipment, comprising: an operating table; a first simulated rotating platform rotatably connected to the upper rear edge of the operating table; a second simulated rotating platform rotatably connected inside the first simulated rotating platform; and a third simulated rotating platform rotatably connected inside the first simulated rotating platform.

This achieves a simulation effect of "the larger the patient's body size, the greater the rib strength," solving the problems of existing cardiac resuscitation training models having fixed structures, unadjustable compressive deformation performance, and inability to better mimic patients of different ages, genders, and body types, and the inability to improve similarity to actual rescue situations through adjustments to the training tool's structure.

Description

Technical Field

[0001] This invention relates to the field of medical training equipment technology, and in particular to a cardiac resuscitation training device. Background Technology

[0002] During cardiopulmonary resuscitation (CPR) training, a mannequin is used as a training device. During training, the hands are used to press evenly on the upper chest. Through external chest compressions, blood flow is generated in the heart and major blood vessels to maintain the minimum blood requirements of major organs such as the heart and brain.

[0003] Patients of different ages, genders, and body types have varying bone density and thickness. When performing cardiac resuscitation, it is necessary to apply appropriate force and depth of pressure to improve the effectiveness of cardiac resuscitation treatment and avoid secondary trauma caused by uneven pressure control. However, existing cardiac resuscitation training models have fixed structures and their compressive deformation performance is not adjustable. They cannot better mimic patients of different ages, genders, and body types, nor can they improve the similarity to actual rescue situations by adjusting the structure of the training tools.

[0015] This invention provides a cardiac resuscitation training device, the beneficial effects of which are:

[0016] 1. The cardiac resuscitation training model of this invention is installed on the operating table. It has a convenient structure. After the cardiac resuscitation training is completed, the locking block push handle is pushed down to lower the lifting locking block and separate the locking upper groove from the positioning end groove. The first simulation rotating table can then be pulled out to the left to disassemble the training device.

[0017] 2. When the cardiac resuscitation training device of the present invention is used, it can simulate the body shape of different patients and adjust the elasticity of the training device by changing the body shape. When the pressing area of ​​the cardiac resuscitation training device increases, the number of springs at the bottom that participate in the support increases simultaneously, thereby changing the resistance of the pressing device and realizing the simulation effect that "the larger the body size of the patient, the greater the strength of the ribs".

[0018] 3. In the cardiac resuscitation training device of this application, the compression amplitude needs to be limited during training. For patients with small body size, the compression amplitude should not be too large, while for patients with large body size, the compression amplitude needs to be adjusted accordingly to make the compression more effective. In order to achieve training in compression amplitude control, a trigger alarm is set. The trigger alarm is located on the lower surface of the fourth simulation stage. The lower end of the trigger alarm is equipped with an alarm trigger button. When the device is being pressed, the trigger alarm moves down. When the alarm trigger button touches the operating table, the trigger alarm sounds to remind the user. The height of the trigger alarm can be adjusted by the screw drive of the trigger push rod, thereby adjusting the alarm amplitude and playing a role in training the ability to control the compression amplitude.

[0033] The operating platform 1 has a rear edge plate 101 fixedly connected to its rear edge. A rod groove 102 is formed in the middle of the upper surface of the rear edge plate 101. A limiting rear groove 103 is formed through the front of the rod groove 102. A lifting locking block 104 is movably connected inside the rod groove 102.

The rotating table hinge rod 201 is rotatably connected to the rear end of the operating table 1. On the articulated end cylinder 108, after the cardiac resuscitation training is completed, push the locking block push handle 106 downwards to lower the lifting locking block 104, causing the locking upper groove 107 to separate from the positioning end groove 202. Then, the first simulation rotating table 2 can be pulled out to the left to disassemble the training equipment. For reinstallation, insert the rotating table hinge rod 201 into the articulated end cylinder 108 and press the locking block push handle 106 downwards, so that the positioning end groove 202 is positioned above the protrusion of the locking upper groove 107. This causes the lifting locking block 104 to move upwards under the elastic force of the locking push spring 105, and the locking upper groove 107 to fit against the positioning end groove 202, thus aligning the positioning end groove 202. The limit switch is used to reinstall the first simulated rotary table 2 on the operating table 1. The first simulated rotary table 2 has a rotary table groove 203 in the middle.

A second top spring 306 is sleeved on the second guide post 305, and the upper end of the second top spring 306 is fixedly connected to the lower surface of the second simulated rotating platform 3. The second simulated rotating platform 3 is located inside the first simulated rotating platform 2. The second rotating hole 301 is rotatably connected to the hinge support shaft 206, serving as a hinge. The third simulated rotating platform 4 has a third rotating hole 401 extending horizontally through it. Two third inserts 402 are fixedly connected to the lower surface of the third simulated rotating platform 4. The second interface 303 is provided at the front of the inner edge of the lower surface of the third simulated rotating platform 4. A third interface 403 is provided at the front edge.

At the same time, it also serves as a limiting function for each part of the frame, so that the central frame cannot be higher than the outer frame, which facilitates the docking of each frame.

[0034] The fourth simulation rotating platform 5 has a fourth rotating hole 501 that runs horizontally through it. Two fourth inserts 502 are fixedly connected to the lower surface of the fourth simulation rotating platform 5. A fourth limiting protrusion 503 is fixedly connected to the front end of the lower surface of the fourth simulation rotating platform 5. A fourth top spring 504 is fixedly connected to the middle of the lower surface of the fourth simulation rotating platform 5. A synchronous rack and pinion locking rod 505 is rotatably connected inside the fourth insert 502. Two lower guide rods 506 are fixedly connected to the lower surface of the fourth simulation rotating platform 5, and the lower guide rods 506 are perpendicular to the lower surface of the fourth simulation rotating platform 5. The shaft of the adjusting handle 6 is rotatably connected to the fourth simulation rotating platform 5, and the lower end of the shaft of the adjusting handle 6 is fixedly connected to an adjusting active gear 601. When it is necessary to adjust the pressing area and pressing resistance of the cardiac resuscitation training device, the adjusting handle 6 is rotated to adjust the active gear 601. When gear 601 rotates, it adjusts the active gear 601 and the synchronous rack and pinion lock rod 505 to form a rack and pinion transmission, driving the two synchronous rack and pinion lock rods 505 to move outward synchronously. During the outward movement of the synchronous rack and pinion lock rods 505, they are inserted into the third sleeve 402, the second sleeve 302, and the first sleeve 205 in sequence. When the synchronous rack and pinion lock rod 505 is inserted into the third sleeve 402, the third simulated rotating platform 4 and the fourth simulated rotating platform 5 rotate accordingly. The fourth top spring 504 and the third top spring 406 participate in the support at the same time, improving the support force. In the same way, as the synchronous rack and pinion lock rod 505 continues to move and is inserted into the second sleeve 302 and the first sleeve 205, the participation of the top spring will gradually increase, further adjusting the compressive strength of the device, thereby better mimicking the bone strength of patients with different body types and achieving better training effects.

[0035] Example 2: The linkage gear 7 meshes with and adjusts the drive gear 601. A linkage screw 701 is fixedly connected to the lower end of the linkage gear 7.

The lower end of the trigger alarm 8 is provided with... An alarm trigger button 803 is provided, and a buzzer is provided on the right side of the trigger alarm 8. When adjusting the adjustment handle 6, the linkage gear 7 meshes with the adjustment drive gear 601 and rotates with the adjustment drive gear 601. When the linkage screw 701 rotates, it forms a helical transmission with the screw hole of the trigger push rod 802, thereby driving the trigger alarm 8 to move longitudinally on the lower guide support rod 506 to change its height. When the device is pressed, the trigger alarm 8 moves down. When the alarm trigger button 803 contacts the operating table 1, the trigger alarm 8 sounds an alarm to remind the user to control the pressing intensity.

[0036] Specific usage and function: In this invention, when using the cardiac resuscitation training device for exercise, insert the rotating platform hinge rod 201 into the hinge end cylinder 108, and press down the locking block push handle 106, so that the positioning end groove 202 is above the protrusion of the locking upper groove 107. This causes the lifting locking block 104 to move upward under the elastic force of the locking push spring 105, and the locking upper groove 107 fits against the positioning end groove 202, limiting the positioning end groove 202. This completes the installation of the first simulated rotating platform 2. During training, the device is operated by hand... Press the upper surface of the cardiac resuscitation training device for training. During training, if you want to adjust the device to simulate patients of different ages or body types, you can turn the adjustment handle 6 to rotate the adjustment drive gear 601. The adjustment drive gear 601 and the synchronous rack and pinion locking rod 505 form a rack and pinion transmission, driving the two synchronous rack and pinion locking rods 505 to move outward synchronously. During the outward movement of the synchronous rack and pinion locking rods 505, the third insert 402, the second insert 302, and the first insert 205 are inserted in sequence. When the synchronous rack and pinion locking rods 505... When inserted into the third sleeve 402, the third simulation rotating platform 4 and the fourth simulation rotating platform 5 rotate accordingly. The fourth top spring 504 and the third top spring 406 simultaneously participate in the support, improving the support force. On the same principle, the synchronous rack and pinion locking rod 505 continues to move. During the insertion of the second sleeve 302 and the first sleeve 205, the participation of the top spring will gradually increase, further adjusting the compressive strength of the device, thereby better mimicking the bone strength of patients of different body types. At the same time, the linkage gear 7 meshes with the adjusting active gear 601 and rotates with the adjusting active gear 601. When the linkage screw 701 rotates, it forms a spiral transmission with the screw hole of the trigger push rod 802, thereby driving the trigger alarm 8 to move longitudinally on the lower guide rod 506 to change the height, so that larger patients need a greater pressing amplitude. During the pressing of the device, the trigger alarm 8 moves down. When the alarm trigger button 803 contacts the operating table 1, the trigger alarm 8 sounds an alarm, reminding the user to control the pressing amplitude, thereby realizing the training of different pressing amplitudes for people of different body types.
