Description

Technical Field

[0001] The present invention relates to the technical field of medical teaching aids, and particularly to a simulated rib fracture mechanism. Background Art

[0002] In the field of medical teaching, simulated rib fracture mechanisms play a crucial role in cultivating the clinical palpation skills of medical students. Although traditional simulated rib fracture mechanisms can simulate the situation of rib fractures to a certain extent, they have many limitations.

[0003] Early simulation mechanisms were mostly fixed models, which could only present a single fracture state at specific rib positions, such as only simulating the inward fracture of the rib to form a depression, and could not show the diversity of fractures. This led to a too single simulated scenario for medical students during training, making it difficult to cope with the complex and changeable fracture situations in actual clinical practice. When facing assessments, only teaching aids for single simulated rib fractures could be used, and the accuracy of the assessment results was not high. In addition, the external latex of traditional simulation teaching aids was generally a fixed structure and could not simulate the thickness of internal bones and external muscles of patients with different body shapes, resulting in students only being able to remember the pressing touch of rib fractures of this body shape and not being able to achieve a sufficient teaching effect. When students actually face rib fractures in patients, it is difficult to make accurate judgments based on patients with different body shapes. Summary of the Invention

[0017] 1. When it is necessary to use the simulated rib fracture mechanism for teaching or assessment, start the motor. Drive the full cone gear six to rotate through the full cone gear five, thereby drive the cam to rotate through the full cone gear four and the reducer, and then drive the piston plate to slide up and down inside the medium storage bin through the top shaft and the sliding seat. Randomly inject the medium inside the medium storage bin into the inside of the medium cavity through the conduit, so that the latex simulation skin is inflated, realizing the simulation of the muscle thickness at the ribs of different body shapes, enabling students to learn the feel of the rib fracture at the ribs of patients with different body shapes during the learning process, with better learning effects, and making the assessment of students have a certain degree of randomness.

[0018] 2. When the full cone gear six drives the rotating shaft three to rotate, through the cooperation of the sun gear, the planet gear and the fixing frame, drive the tooth ring to rotate and the support bin to rotate, so as to randomly rotate the chute to the inside of any one of the simulated rib strips. Since adjusting the slot inside the adjusting support block can cause this simulated rib strip to lose support at the fracture, students will feel a sense of rib fracture when pressing, realizing that any one of the simulated rib strips simulates a fractured rib due to loss of support, further enhancing the randomness of the assessment.

[0019] 3. When the rotating shaft three drives the semi-cone gear to rotate, it intermittently drives the full-cone gears one on the left and right sides to rotate, thereby intermittently driving the worm gear to rotate through the worm, and then intermittently driving the large pulley to rotate through the rotating shaft one. Further, it drives the rotating shaft two to rotate through the transmission belt and the small pulley. Since the worms and worm gears on the left and right sides are symmetrical to each other, finally, it drives the adjusting support block to reciprocate up and down inside the chute through the turntable and the driving frame, achieving the ability to slot and randomly stay at the upper and lower fracture points of the simulated rib strip, further enhancing the randomness of the assessment.

[0020] 4. When the rotating shaft three drives the full-cone gear three to rotate through the full-cone gear two, it drives the bidirectional threaded screw rod to move left and right at the right end of the universal coupling through the universal coupling, thereby driving the top strip to extend to the right or retract to the left inside the slot. When it moves to the upper and lower random fracture points of a random simulated rib strip, it can randomly support or not support the fracture point of the simulated rib strip. When supporting, it can simulate the situation of rib fracture outwards, and when not supporting, the student will feel a depression when pressing the fracture point. This not only realizes the ability to simulate the situations of rib fracture outwards and inwards, but also further enhances the randomness of the assessment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following combines the specification drawings and embodiments to further describe in detail the specific implementation mode of the present invention. The following embodiments are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] As Figures 1-6 shown, this implementation mode proposes a simulated rib fracture mechanism, including a simulation rib structure 1. An adjusting support structure 2 is rotatably connected inside the simulation rib structure 1. The lower end of the simulation rib structure 1 is fixedly connected to a base 5. A driving structure 4 is arranged on the left side of the inner middle part of the base 5, and a medium replenishing structure 3 is fixedly connected to the right side of the inner middle part of the base 5;

[0031] The medium replenishing structure 3 includes a fourth full bevel gear 31 and a medium storage bin 37. A reducer 32 is fixedly connected to the middle of the fourth full bevel gear 31. The right end output of the reducer 32 is fixedly connected to a cam 33. A top shaft 34 is rotatably connected to the right side of the cam 33.

The outer periphery of the piston plate 36 is slidably connected inside the medium storage bin 37.

[0032] In this embodiment, the simulation rib structure 1 includes a latex simulation skin 11. A medium cavity 12 is opened in the middle of the latex simulation skin 11. A top plate 13 is fixedly connected to the inner top of the latex simulation skin 11. The outer periphery of the top plate 13 is evenly distributed with chassis 14. The lower part of the inner side of the latex simulation skin 11 is fixedly connected with simulation rib strips 15. The lower ends of the chassis 14 are rotatably connected to the upper ends of the simulation rib strips 15, and each chassis 14 is broken into three sections, and the outside is fixedly connected to the inner side wall of the latex simulation skin 11.

[0033] In this embodiment, the lower end of the speed reducer 32 is fixedly connected to the middle right side of the inner bottom wall of the base 5, and the inside of the medium storage bin 37 is communicated with the inside of the medium cavity 12 through a conduit.

[0034] Specifically, when it is necessary to use the simulated rib fracture mechanism for teaching or assessment, the motor 41 is started, and the whole bevel gear six 43 is driven to rotate by the whole bevel gear five 42, so as to drive the cam 33 to rotate through the whole bevel gear four 31 and the speed reducer 32, and then drive the piston plate 36 to slide up and down inside the medium storage bin 37 through the top shaft 34 and the sliding seat 35, and randomly inject the medium inside the medium storage bin 37 into the inside of the medium cavity 12 through the conduit, so that the latex simulation skin 11 is inflated, realizing the simulation of the muscle thickness at the ribs of different body shapes, enabling the trainees to learn the feel of the rib fracture of patients with different body shapes during the learning process, with better learning effects, and making it have a certain degree of randomness when students are being assessed.

[0035] In this embodiment, the drive structure 4 includes a motor 41. The right drive end of the motor 41 is fixedly connected with a whole bevel gear five 42. The whole bevel gear five 42 is meshed with a whole bevel gear six 43. The middle of the whole bevel gear six 43 is fixedly connected with a rotating shaft three 44. The outer circumference of the middle and lower part of the rotating shaft three 44 is fixedly connected with a sun gear 45. There is a fixing frame 48 at the upper end of the sun gear 45. The lower end of the fixing frame 48 is fixedly connected to the middle of the inner lower end of the support bin 21. The outer circumference of the inner lower end of the support bin 21 is fixedly connected with a toothed ring 47. The toothed rings 47 are evenly distributed on the outer circumference of the fixing frame 48. The sun gear 45 is meshed with the planet gears 46 respectively, and the planet gears 46 are meshed with the toothed ring 47 respectively.

[0036] In this embodiment, the inside of the half bevel gear 26 is fixedly connected to the outer circumference of the upper end of the rotating shaft three 44. The upper end of the rotating shaft three 44 is rotatably connected to the inner top of the support frame 25. The inside of the whole bevel gear two 216 is fixedly connected to the outer circumference of the middle and upper part of the rotating shaft three 44.

[0037] In this embodiment, the whole bevel gear four 31 is meshed with the whole bevel gear six 43. The outer circumference of the middle and lower part of the rotating shaft three 44 is rotatably connected to the middle opening at the upper end of the base 5.

[0038] Specifically, when the bevel gear six 43 drives the rotation of the rotating shaft three 44, through the cooperation of the sun gear 45, the planet gear 46 and the fixing bracket 48, it drives the rotation of the toothed ring 47 and the support bin 21 to rotate, so that the chute 22 is randomly rotated to the inside of any one of the simulation rib strips 15. Since the slot 24 inside the adjusting support block 23 can cause the simulation rib strip 15 to lose support at the fracture point, when the student presses it, there will be a feeling of rib fracture, realizing that any one of the simulation rib strips 15 simulates a fractured rib due to the loss of support. At the same time, the simulation rib fracture mechanism can judge the moving position of the slot 24 through the number of rotation turns of the motor 41, further improving the randomness of the assessment.

[0039] In this embodiment, the adjusting support structure 2 includes a support bin 21 and a telescopic support assembly. A chute 22 is opened on the right side of the support bin 21. An adjusting support block 23 is slidably connected inside the chute 22. A slot 24 is opened in the middle of the right end of the adjusting support block 23. The left end of the adjusting support block 23 is fixedly connected to a driving frame 222. Turntables 215 are fixedly connected to the front and rear sides of the left end of the driving frame 222. A support frame 25 is fixedly connected to the middle of the support bin 21. A half bevel gear 26 is arranged inside the support frame 25. Full bevel gears one 27 are arranged on both sides of the half bevel gear 26. Worms 28 are fixedly connected to the middle of the full bevel gears one 27. The worms 28 are all meshed with worm wheels 29. Rotating shafts one 210 are fixedly connected to the middle of the worm wheels 29. Large belt pulleys 211 are fixedly connected to the ends of the rotating shafts one 210 far away from the worm wheels 29. The large belt pulleys 211 are all connected to small belt pulleys 213 through transmission belts 212. Rotating shafts two 214 are fixedly connected to the middle of the small belt pulleys 213.

[0040] In this embodiment, the ends of the worms 28 far away from the full bevel gears one 27 are all rotatably connected to the middle parts of both sides of the support frame 25, and the middle parts of the rotating shafts one 210 are fixedly connected to the middle parts of the front and rear sides of the support frame 25.

[0041] In this embodiment, the ends of the rotating shafts two 214 close to the driving frame 222 are all fixedly connected to the middle of the driving frame 222, and the middle parts of the rotating shafts two 214 are rotatably connected to the front and rear sides of the lower end of the support frame 25.

[0042] Specifically, when the rotating shaft three 44 drives the half bevel gear 26 to rotate, it intermittently drives the bevel gears one 27 on both the left and right sides to rotate, thereby intermittently driving the worm wheel 29 to rotate through the worm 28, and further intermittently driving the large pulley 211 to rotate through the rotating shaft one 210. Then, it drives the rotating shaft two 214 to rotate through the transmission belt 212 and the small pulley 213. Since the worms 28 and the worm wheels 29 on both the left and right sides are symmetrically arranged, finally, the adjusting support block 23 is driven to reciprocate up and down inside the sliding groove 22 through the turntable 215 and the driving frame 222, enabling the grooving 24 to randomly stay at the upper and lower fracture points of the corresponding simulated rib strip 15, further enhancing the randomness of the assessment.

[0043] In this embodiment, the telescopic support assembly includes a bevel gear two 216. The bevel gear two 216 is meshed with a bevel gear three 217. A universal coupling 218 is fixedly connected to the middle of the bevel gear three 217. A bidirectional threaded rod 219 is fixedly connected to the right end of the universal coupling 218. A driving block 220 is threadedly connected to the right end of the bidirectional threaded rod 219. A top bar 221 is fixedly connected to the right end of the driving block 220. The right end of the top bar 221 penetrates through the middle of the left side of the adjusting support block 23 and extends into the grooving 24.

[0044] Specifically, when the rotating shaft three 44 drives the bevel gear three 217 to rotate through the bevel gear two 216, the bidirectional threaded rod 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 grooving 24. When it moves to the upper and lower random fracture points of a random simulated rib strip 15, it can randomly support or not support the fracture point of the simulated rib strip 15. When supporting, it can simulate the situation of rib fracture outwards. When not supporting, the student will feel a depression when pressing the fracture point at this place. It not only realizes the simulation of rib fractures outwards and inwards, but also further enhances the randomness of the assessment.

[0045] Working principle: When it is necessary to use the simulated rib fracture mechanism for teaching or assessment, start the motor 41. The full-cone gear five 42 drives the full-cone gear six 43 to rotate, thereby driving the cam 33 to rotate through the full-cone gear four 31 and the reducer 32. Then, through the top shaft 34 and the sliding seat 35, the piston plate 36 slides up and down inside the medium storage bin 37, and randomly injects the medium inside the medium storage bin 37 into the inside of the medium chamber 12 through the conduit, causing the latex simulation skin 11 to expand, realizing the simulation of the muscle thickness at the ribs of different body shapes, enabling trainees to learn the feel of rib fractures at the ribs of patients with different body shapes during the learning process, with better learning effects, and making the assessment of students have a certain degree of randomness. When the full-cone gear six 43 drives the rotating shaft three 44 to rotate, through the cooperation of the sun gear 45, the planet gear 46 and the fixing frame 48, the toothed ring 47 is driven to rotate and the support bin 21 rotates, thereby randomly rotating the chute 22 to the inside of any one of the simulated rib strips 15. Since the slot 24 inside the adjusting support block 23 can cause this simulated rib strip 15 to lose support at the fracture point, students will feel a rib fracture when pressing, realizing that any one of the simulated rib strips 15 simulates 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 through the number of rotation turns of the motor 41, further improving the randomness of the assessment. When the rotating shaft three 44 drives the half-cone gear 26 to rotate, it intermittently drives the full-cone gears one 27 on the left and right to rotate, thereby intermittently driving the worm gear 29 to rotate through the worm 28, and then intermittently driving the large pulley 211 to rotate through the rotating shaft one 210. Then, through the transmission belt 212 and the small pulley 213, the rotating shaft two 214 is driven to rotate. Since the worms 28 and the worm gears 29 on the left and right are symmetrical to each other, finally, through the turntable 215 and the drive frame 222, the adjusting support block 23 slides reciprocally up and down inside the chute 22, realizing that the slot 24 can randomly stop at the upper and lower two fracture points of this simulated rib strip 15, further improving the randomness of the assessment. When the rotating shaft three 44 drives the full-cone gear two 216 to drive the full-cone gear three 217 to rotate, it drives the bidirectional threaded screw rod 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 moving to the upper and lower random two fracture points of any one of the simulated rib strips 15, it can randomly support or not support the fracture point of the simulated rib strip 15. When supporting, it can simulate the situation of rib fracture outwards. When not supporting, students will feel a sinking feeling when pressing the fracture point at this place, not only realizing the simulation of the situations of rib fracture outwards and inwards, but also further improving the randomness of the assessment.

[0046] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
