Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical teaching aids, in particular to a mechanism for simulating rib fractures. Background Art
[0002] In the field of medical education, the simulated rib fracture mechanism plays a vital role in cultivating the clinical palpation skills of medical students. Although the traditional simulated rib fracture mechanism can simulate the situation of rib fracture to a certain extent, it has many limitations. Early simulation mechanisms were mostly fixed modes, and could only present a single fracture state at a specific rib position, such as only simulating the inward fracture of the rib to form a depression, and were unable to show the diversity of fractures. This resulted in medical students facing too single a simulation scenario during training, making it difficult to cope with the complex and changeable fracture situations in actual clinical practice. When facing assessments, they could only use a single teaching aid to simulate rib fractures, and the assessment results were not accurate. In addition, the external latex of traditional simulation teaching aids is generally a fixed structure, which cannot simulate the thickness of the internal bones and external muscles of patients of different body shapes, resulting in students only being able to remember the pressing feel of the broken ribs of this body shape, and being unable to achieve the full teaching effect, making it difficult for students to make accurate judgments based on patients of different body shapes when they actually face patients with rib fractures.

[0029] Specifically, when the full bevel gear six 43 drives the rotating shaft three 44 to rotate, the sun gear 45, the planetary gear 46 and the fixed frame 48 cooperate to drive the gear ring 47 to rotate the support bin 21, thereby randomly rotating the slide groove 22 to the inner side of any simulated rib strip 15. Since the slot 24 inside the adjusting support block 23 can make the simulated rib strip 15 lose support at the fracture point, the students will feel the rib fracture when pressing it, so that any simulated rib strip 15 can simulate a fractured rib due to loss of support. At the same time, the simulated rib fracture mechanism can judge the moving position of the slot 24 by the number of rotations of the motor 41, further improving the randomness of the assessment.
[0030] In this embodiment, the adjustable support structure 2 includes a support bin 21 and a telescopic support assembly. A slide groove 22 is provided on the right side of the support bin 21. An adjustable support block 23 is slidably connected inside the slide groove 22. A slot 24 is provided in the middle of the right side of the adjustable support block 23. A drive frame 222 is fixedly connected to the left end of the adjustable support block 23. A turntable 215 is fixedly connected to the front and rear sides of the left end of the drive frame 222. A support frame 25 is fixedly connected to the middle of the support bin 21. A semi-slip member is provided inside the support frame 25. Bevel gear 26 and half bevel gear 26 are both provided with full bevel gear 1 27 on both sides, the middle part of full bevel gear 1 27 is fixedly connected with worm 28, worm 28 is meshingly connected with worm wheel 29, the middle part of worm wheel 29 is fixedly connected with rotating shaft 1 210, the end of rotating shaft 1 210 away from worm wheel 29 is fixedly connected with large pulley 211, large pulley 211 is connected with small pulley 213 through transmission belt 212, the middle part of small pulley 213 is fixedly connected with rotating shaft 2 214.

[0032] In this embodiment, one end of the second rotating shaft 214 close to the driving frame 222 is fixedly connected to the middle of the driving frame 222, and the middle of the second rotating shaft 214 is rotatably connected to the front and rear sides of the lower end of the supporting frame 25.
[0033] Specifically, when the rotating shaft three 44 drives the semi-bevel gear 26 to rotate, it intermittently drives the full bevel gear one 27 on the left and right sides to rotate, thereby intermittently driving the worm wheel 29 to rotate through the worm 28, and then intermittently drives the large pulley 211 to rotate through the rotating shaft one 210, and then drives the rotating shaft two 214 to rotate through the transmission belt 212 and the small pulley 213. Since the worm 28 and the worm wheel 29 on the left and right sides are symmetrical, the adjusting support block 23 is finally driven by the turntable 215 and the driving frame 222 to slide back and forth up and down inside the slide groove 22, so that the slot 24 can randomly stay at the upper and lower fracture points of the simulated rib strip 15, further improving the randomness of the assessment.
[0034] In this embodiment, the telescopic support assembly includes a full bevel gear 216, which is meshingly connected with a full bevel gear 3 217, and a universal coupling 218 is fixedly connected to the middle of the full bevel gear 3 217.

The right end of the drive block 220 is fixedly connected to a top strip 221, and the right end of the top strip 221 passes through the middle of the left side of the adjustment support block 23 and extends to the interior of the slot 24.
[0035] Specifically, when the rotating shaft three 44 drives the full bevel gear three 217 to rotate through the full bevel gear two 216, the bidirectional threaded screw 219 is driven to move left and right at the right end of the universal coupling 218 through the universal coupling 218, thereby driving the top bar 221 to extend to the right or retract to the left inside the slot 24. When it moves to the two random upper and lower broken points of a random simulated rib bar 15, the broken part of the simulated rib bar 15 can be randomly supported or not supported. When supported, it can simulate the situation of the rib fracture outward. When not supported, students will feel a sinking feeling when pressing the fracture point. Not only can it simulate the situation of the rib fracture outward and inward, but it also further improves the randomness of the assessment.
[0036] Working principle: when it is necessary to use the simulated rib fracture mechanism for teaching or assessment, start the motor 41, and drive the full bevel gear 6 43 to rotate through the full bevel gear 5 42, thereby driving the cam 33 to rotate through the full bevel gear 4 31 and the reducer 32, and then driving the piston plate 36 to slide up and down inside the medium storage bin 37 through the top shaft 34 and the slide seat 35, and randomly injecting the medium inside the medium storage bin 37 into the medium cavity 12 through the catheter, so that the latex simulation skin 11 is expanded, and the muscle thickness at the ribs of different body shapes is simulated, so that students can learn the feel of the broken ribs of patients with different body shapes during the learning process, and the learning effect is better, and it makes the students progress. There is a certain randomness in the assessment. When the full bevel gear six 43 drives the rotating shaft three 44 to rotate, the sun gear 45, the planetary gear 46 and the fixed frame 48 cooperate to drive the gear ring 47 to rotate the support bin 21, so that the slide groove 22 is randomly transferred to the inner side of any simulated rib strip 15. Since the slot 24 inside the adjusting support block 23 can make the simulated rib strip 15 lose support at the fracture point, the student will feel the rib fracture when pressing it, so that any simulated rib strip 15 can simulate the fractured rib due to the loss of support. At the same time, the simulated rib fracture mechanism can judge the moving position of the slot 24 by the number of rotations of the motor 41, which further improves the randomness of the assessment. When the rotating shaft three 44 drives the semi-bevel gear 26 to rotate, it intermittently drives the full bevel gear one 27 on the left and right sides to rotate, thereby intermittently driving the worm wheel 29 to rotate through the worm 28, and then intermittently drives the large pulley 211 to rotate through the rotating shaft one 210, and then drives the rotating shaft two 214 to rotate through the transmission belt 212 and the small pulley 213. Since the worm 28 and the worm wheel 29 on the left and right sides are symmetrical to each other, the adjusting support block 23 is finally driven to slide up and down inside the slide groove 22 through the turntable 215 and the driving frame 222, so that the slot 24 can randomly stay at the upper and lower fracture points of the simulated rib strip 15, further improving the randomness of the assessment. When shaft three 44 drives full bevel gear three 217 to rotate through full bevel gear two 216, it drives the bidirectional threaded screw 219 to move left and right at the right end of the universal coupling 218 through the universal coupling 218, thereby driving the top bar 221 to extend to the right or retract to the left inside the slot 24. When it moves to the two random upper and lower fracture points of a random simulated rib bar 15, it can randomly support or not support the fracture point of the simulated rib bar 15. When supported, it can simulate the situation of the rib fracture outward. When not supported, students will feel a sinking feeling when pressing the fracture point. It not only realizes the simulation of the outward and inward fractures of the ribs, but also further improves the randomness of the assessment.
