Description

Technical Field

[0001] This invention relates to the field of rehabilitation training technology, specifically a bridge-type exercise rehabilitation training bed. Background Technology

[0002] The bridge exercise is a common training method in medical rehabilitation. It helps improve the pelvis's control and coordination of the lower limbs, which is the foundation for successful standing and walking. The bridge exercise can effectively train the hip extensor muscles and activate the gluteal muscles. It is a simple and effective movement. Common human postures include excessive forward tilting of the hip joint, which makes hip extension and activation of the gluteal muscles extremely difficult. Therefore, the bridge exercise can break this difficult pattern. It is suitable for people with stiffness and discomfort in the shoulder, hip, knee, elbow, and ankle joints, as well as those with mild arthritis who want to repair and heal.

[0003] During bridge exercise training, the patient lies supine on the bed with both legs bent, keeping the feet fixed, and the buttocks facing down, close to the thighs. The patient then lifts the buttocks upwards, exerting force to raise them to the maximum position. After holding the position for a certain period of time, the buttocks are lowered back to the bed.

[0004] However, when patients perform bridge exercise rehabilitation training on their own, when their hips are raised to the maximum position, they are prone to falling suddenly from a height and hitting the bed due to lack of strength or improper movement, which can cause lumbar injury and unnecessary safety hazards to the patients.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: a bridge-type exercise rehabilitation training bed, including a bed body 1, and a protective mechanism 2 provided on the bed body 1 for protecting the patient during bridge-type exercise rehabilitation training;

[0031] Please see Figure 1 , Figure 2 and Figure 4The protective mechanism 2 includes a protective groove 201 formed on the bed body 1, a protective plate 202 slidably connected to the protective groove 201, a U-shaped plate 203 fixedly connected to the lower side of the bed body 1, two symmetrically arranged protective rods 204 slidably connected to the U-shaped plate 203, a first mounting plate 205 fixedly connected to one end of the two protective rods 204 near the bed body 1, two symmetrically arranged first fixing plates 206 fixedly connected to the other side of the first mounting plate 205, a first rotating shaft 207 rotatably connected between the two first fixing plates 206, a second fixing plate 208 fixedly connected to the side wall of the first rotating shaft 207, the protective plate 202 fixedly connected to the second fixing plate 208, a first spring 209 sleeved on the side wall of the two protective rods 204, the two ends of the two first springs 209 respectively connected to the first mounting plate 205 and the U-shaped plate 203, and a speed limiting mechanism 7 for limiting the speed when the protective plate 202 falls on the U-shaped plate 203.

[0032] It should be noted that the protective mechanism 2 protects the patient's lower back, preventing injury from a high-speed fall and improving the patient's safety during bridge exercise rehabilitation training.

[0033] Please see Figure 2 , Figure 3 and Figure 5 The bed 1 is provided with a support mechanism 4 for supporting the patient's legs. The support mechanism 4 includes a second mounting plate 401 slidably connected to the lower side of the bed 1. Two sets of support rods 402 are fixedly connected to the second mounting plate 401 and arranged symmetrically in pairs. The other ends of the two support rods 402 are fixedly connected to support plates 403. The two support plates 403 have rounded corners on the side closest to the patient. Two support grooves 404 are opened on the bed 1, and the two support plates 403 slide on the support grooves 404.

[0034] It should be noted here that the support mechanism 4 will support the patient's legs, thereby ensuring that the degree of leg flexion meets the training standards.

[0035] Please see Figure 2 and Figure 3 The bed body 1 is provided with a drive mechanism 5 for driving the support plate 403. The drive mechanism 5 includes two drive tubes 501 that are fixedly connected to the lower side of the bed body 1 and are symmetrically arranged. The two drive tubes 501 are located between the two support plates 403. A drive rod 502 is slidably connected to one of the two drive tubes 501. One end of the drive rod 502 is fixed to the second mounting plate 401. A threaded rod 503 is threadedly connected to the other of the two drive tubes 501. One end of the threaded rod 503 is rotatably connected to the second mounting plate 401. A motor 504 is provided on the second mounting plate 401. The output end of the motor 504 is connected to the threaded rod 503.

[0036] It should be noted here that the drive mechanism 5 facilitates the up-and-down movement of the support plate 403.

[0037] Please see Figure 1 , Figure 2 and Figure 4 The second mounting plate 401 is provided with a compression mechanism 6 for compressing the protective plate 202. The compression mechanism 6 includes a first L-shaped plate 601. One end of the first L-shaped plate 601 is connected to the second mounting plate 401. The two protective rods 204 are fixedly connected to the compression plate 602 at the ends away from the bed body 1. The side wall of the other end of the first L-shaped plate 601 abuts against the side wall of the compression plate 602 near the protective plate 202. The first spring 209 is in a compressed state under the pressure of the first L-shaped plate 601.

[0038] It should be noted that the compression mechanism 6 allows the protective plate 202 to be placed inside the protective groove 201 when not in use, thus making it convenient for the patient to lie on the bed 1.

[0039] Please see Figure 4 , Figure 7 and Figure 8 The speed limiting mechanism 7 includes two symmetrically arranged third mounting plates 701 fixedly connected to the side of the U-shaped plate 203 away from the bed body 1. A second rotating shaft 702 is rotatably connected between the two third mounting plates 701. A speed limiting block 703 is fixedly connected to the side wall of the second rotating shaft 702. One end of the second rotating shaft 702 passes through the third mounting plate 701 and is fixedly connected to a mounting ring 704. Multiple third fixing plates 705 are fixedly connected to the side wall of the mounting ring 704. Each third fixing plate 705 is connected to a speed limiting block 703. Three rotating shafts 706 are rotatably connected to speed limiting tubes 707. Speed ​​limiting rods 708 are slidably connected to each speed limiting tube 707. Speed ​​limiting balls 709 are fixedly connected to one end of each speed limiting rod 708 away from the speed limiting tube 707. A second spring is fixedly connected to the bottom wall of each speed limiting tube 707. The other end of each second spring is connected to the speed limiting rod 708. A speed limiting ring 710 is fixedly connected to the side wall of the third mounting plate 701 and is concentrically arranged with the second rotating shaft 702. Each speed limiting ball 709 slides on the inner wall of the speed limiting ring 710.

[0040] It should be noted that, through the setting of the speed limiting mechanism 7, when the waist falls from a height, it will drive the speed limiting block 703 on the second rotating shaft 702 to rotate. During the rotation of the speed limiting block 703, the second rotating shaft 702 will be driven to rotate through the meshing transmission between the rotating block 805 and the first rotating plate 803. During the rotation of the second rotating shaft 702, the mounting ring 704 will be driven to rotate synchronously. During the rotation of the mounting ring 704, under the action of centrifugal force, the speed limiting ball 709 on the speed limiting rod 708 will be pushed to abut against the speed limiting ring 710, thereby increasing the friction force when the second rotating shaft 702 rotates, and further limiting the descent speed of the protective plate 202.

[0041] Please see Figure 7 The compression plate 602 is provided with a one-way mechanism 8 for rotating the speed limiting block 703 in one direction. The one-way mechanism 8 includes a mounting frame 801 fixedly connected to the side wall of the compression plate 602. A one-way plate 802 is slidably connected to the mounting frame 801. A plurality of first rotating plates 803 are fixedly connected to the one-way plate 802. Each first rotating plate 803 has an inclined surface 804 on the side near the bed 1. A plurality of rotating blocks 805 are fixedly connected to the side wall of the speed limiting block 703. Each rotating block 805 is meshed with the first rotating plate 803.

[0042] It should be noted that the one-way mechanism 8 ensures that the speed limiter 703 will not rotate during the upward movement of the protective plate 202.

[0043] Please see Figure 7 The mounting frame 801 is provided with a telescopic assembly for telescopically extending and retracting the one-way plate 802. The telescopic assembly includes multiple telescopic tubes fixedly connected to the bottom wall of the mounting frame 801. Each telescopic tube is slidably connected with a telescopic rod. One end of each telescopic rod is connected to the one-way plate 802. A third spring is sleeved on the side wall of each telescopic tube. Both ends of each third spring are connected to the bottom wall of the mounting frame 801 and the one-way plate 802, respectively.

[0044] It should be noted here that the telescopic components provide guidance and limit for the movement of the one-way plate 802.

[0045] Please see Figure 1 , Figure 2 and Figure 3 The bed 1 is equipped with a visualization mechanism 9 to facilitate standardized bridge exercise rehabilitation training for patients. The visualization mechanism 9 includes a second L-shaped plate 901 rotatably connected to the bed 1. The second L-shaped plate 901 is equipped with a display screen 903 on the side of the bed 1 near the bed 1 via a fourth fixing plate 902. A visual sensor 905 is connected to the side wall of the bed 1 via a third L-shaped plate 904.

[0046] It should be noted that the visualization mechanism 9 facilitates patients to perform bridge exercise rehabilitation training according to the standardized movements shown on the display screen 903. At the same time, the visual sensor 905 will check the patient's movements and display any non-standard movements on the display screen 903, thereby improving the visualization and standardization of the patient's bridge exercise rehabilitation training.

[0047] Please see Figure 2 , Figure 3 and Figure 6 The bed body 1 is provided with a rotating mechanism 10 for rotating the display screen 903. The rotating mechanism 10 includes a rack 1001 slidably connected to the lower side of the bed body 1. A second rotating plate 1006 is rotatably connected to the side wall of the rack 1001. The other end of the second rotating plate 1006 is connected to the second mounting plate 401. A rotating rod 1004 is fixedly connected to one end of the second L-shaped plate 901 near the bed body 1. The rotating rod 1004 passes through the bed body 1 and is fixedly connected to a gear 1005. The gear 1005 and the rack 1001 are meshed with each other.

[0048] It should be noted that, thanks to the rotating mechanism 10, the display screen 903 will rotate to be above the patient's face after the patient lies down on the bed 1, thus making it easier for the patient to lie on the bed 1.

[0049] Please see Figure 6 The bed body 1 is provided with a sliding assembly 11 to facilitate the sliding of the rack 1001. The sliding assembly 11 includes a sliding guide rail 1102 fixedly connected to the side wall of the bed body 1. A sliding block 1101 is slidably connected to the sliding guide rail 1102. One end of the sliding block 1101 is connected to the rack 1001.

[0050] It should be noted here that the sliding component 11 provides guidance and limit for the movement of the rack 1001.

[0051] Working principle: During bridge exercise rehabilitation training, the patient lies supine on the bed 1 and then raises his / her legs. When raising the legs, the motor 504 is started, which drives the threaded rod 503 to rotate. During the rotation of the threaded rod 503, the support plate 403 is driven to move upward through the threaded engagement of the threaded rod 503 and the drive tube 501 and the guiding action of the drive rod 502. During the upward movement of the support plate 403, the patient's legs are supported, so that the degree of leg flexion meets the training standard.

[0052] After the patient bends their legs, they exert their own force to raise their buttocks to the maximum position. When the buttocks are raised to the maximum position, the patient's waist will move upward simultaneously. During the upward movement of the support plate 403, the first L-shaped plate 601 will also move upward, so that one end of the first L-shaped plate 601 is no longer in contact with the compression plate 602. At this time, under the elastic force of the first spring 209, the protective plate 202 will be pushed upward, so that the protective plate 202 fits against the patient's waist, and the patient's waist will provide support and protection.

[0053] Furthermore, during the upward movement of the protective plate 202, the speed limiting block 703 on the second rotating shaft 702 will be driven to move upward. During the upward movement of the speed limiting block 703, when the rotating block 805 abuts against the first rotating plate 803, under the interaction force of the inclined plane 804 and the extension and retraction of the telescopic component, the first rotating plate 803 will be pushed to retract into the mounting frame 801, so that the speed limiting block 703 will not be driven to rotate during the upward movement of the protective plate 202.

[0054] When patients perform bridge exercise rehabilitation training independently, when their hips are raised to the maximum position, due to exhaustion or improper movements, their lower back may suddenly fall from a height. When the lower back falls from a height, it will drive the speed limiting block 703 on the second rotating shaft 702 to rotate. During the rotation of the speed limiting block 703, the second rotating shaft 702 will be driven to rotate through the meshing transmission between the rotating block 805 and the first rotating plate 803. During the rotation of the second rotating shaft 702, the mounting ring 704 will be driven to rotate synchronously. During the rotation of the mounting ring 704, under the action of centrifugal force, the speed limiting ball 709 on the speed limiting rod 708 will be pushed to abut against the speed limiting ring 710, thereby increasing the friction force when the second rotating shaft 702 rotates, further limiting the descent speed of the protective plate 202, so that the patient's lower back can move downward slowly, avoiding high-speed fall that may cause lower back injury, and improving the safety of patients when performing bridge exercise rehabilitation training.

[0055] Furthermore, as the motor 504 drives the second mounting plate 401 to move upward, it will cause the second rotating plate 1006 to rotate. During the rotation of the second rotating plate 1006, under the action of force and the guidance of the sliding block 1101 and the sliding guide rail 1102, the rack 1001 will be pushed closer to the patient's head. Under the mutual meshing and transmission of the rack 1001 and the gear 1005, the second L-shaped plate 901 on the rotating rod 1004 will be rotated. During the rotation of the second L-shaped plate 901, the display screen 903 on the fourth fixed plate 902 will be rotated to above the patient's face, so that the patient can perform bridge exercise rehabilitation training according to the standardized movements on the display screen 903. At the same time, under the inspection of the visual sensor 905, the patient's movements will be checked and any non-standard movements will be displayed on the display screen 903, thereby improving the visualization and standardization of the patient's bridge exercise rehabilitation training.
