Description

Technical Field

[0001] This application relates to the field of orthopedic nursing technology, specifically to a lower limb training and rehabilitation device for orthopedic nursing. Background Technology

[0002] With the improvement of modern medical standards, the success rate of orthopedic surgery and treatment is constantly rising. However, this is also accompanied by higher requirements for postoperative rehabilitation training. As an important part of the human body, the recovery of the function of the lower limbs is crucial to the quality of life of patients. Therefore, lower limb training and rehabilitation devices are needed in orthopedic care.

[0003] For example, a lower limb training and rehabilitation device for orthopedic care, with Chinese patent publication number CN 218686035 U, discloses a lower limb training and rehabilitation device that can be applied to patients with different leg lengths and improves patient comfort during use.

[0004] However, most lower limb training and rehabilitation devices lack a power source. In the initial rehabilitation training, patients may experience insufficient lower limb muscle strength or limited joint mobility, which can easily increase fatigue and discomfort. At the same time, excessive force may increase the risk of wound tearing or other complications, thus having certain drawbacks. Utility Model Content

[0005] Therefore, this application provides a lower limb training and rehabilitation device for orthopedic nursing to solve the problem that existing devices lack a power source, which easily increases patient fatigue and discomfort.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A lower limb training and rehabilitation device for orthopedic nursing includes a seat, mounting rollers and gears. Mounting plates are fixedly installed on both the left and right sides of the front end of the seat, and a fixing plate is provided on the outer side of the mounting plate near the central axis of the seat. A transmission rod is fixedly installed on the upper outer side of the fixing plate.

[0008] The lower end of the fixing plate is fitted with an installation roller by screws;

[0009] The upper part of the mounting plate is provided with a gear, and the outer side of the upper end of the gear is provided with a transmission component. A positioning plate is mounted on the outer side of the gear through a bearing, and a fixing pin located on the outer side of the mounting plate is provided through the inside of the positioning plate.

[0010] Furthermore, the lower rear side of the fixing plate is provided with a groove structure for installing the mounting roller, and a rubber sleeve is sleeved on the outer side of the mounting roller.

[0011] Furthermore, a rectangular structure is provided at one end of the transmission rod near the gear, and the rectangular structure is connected to the gear by a snap-fit ​​method.

[0012] Furthermore, the transmission rod is rotatably connected to the mounting plate, and a torsion spring is provided on the outside of the transmission rod inside the mounting plate.

[0013] Furthermore, the transmission assembly includes a cylinder and a gear plate. The cylinder is mounted on the outer side of the upper end of the mounting plate, and the output end of the cylinder is connected to the gear plate located inside the mounting plate.

[0014] Furthermore, the lower end of the toothed plate is connected to the upper end of the gear, and the toothed plate is slidably connected to the mounting plate.

[0015] Furthermore, the positioning plate has two sets of prefabricated insertion holes through its interior, and the size of the prefabricated insertion holes is adapted to the size of the fixing pin.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] 1. The cylinder and gear plate have a good transmission effect on the gear and transmission rod, which makes it easy to drive the fixed plate to swing on the outside of the mounting plate through the transmission rod. When the patient is in the initial rehabilitation training, the cylinder can drive the mounting roller to lift the patient's lower limbs, thereby achieving the purpose of training and rehabilitation of the patient's lower limbs, so as to reduce the patient's fatigue and discomfort, and at the same time reduce the risk of wound tearing or other complications caused by excessive force.

[0018] 2. When the patient is undergoing post-rehabilitation training, adjust the position of the mounting roller to the inner front side of the lower end of the fixation plate and fix it with bolts. At this time, the patient can place the lower limb on the outer rear end of the rubber sleeve and lift the lower limb to drive the fixation plate and transmission rod to rotate. The transmission rod is equipped with a torsion spring located inside the mounting plate. At this time, the torsion spring deforms and generates a force to restore the transmission rod and fixation plate to their original position. Thus, the mounting roller and rubber sleeve apply force to the patient's lower limb, increasing the intensity of rehabilitation training. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4 As shown in the first aspect embodiment of this application, a lower limb training and rehabilitation device for orthopedic nursing includes: a seat 1, a mounting roller 5, and a gear 9. Mounting plates 2 are fixedly installed on both the left and right sides of the front end of the seat 1, and a fixing plate 3 is provided on the outer side of the mounting plate 2 near the central axis of the seat 1. A transmission rod 4 is fixedly installed on the upper outer side of the fixing plate 3 to stably place the seat 1 on a designated plane. The mounting roller 5 is installed on the lower end of the fixing plate 3 by screws. The fixing plate 3 and the mounting plate 2 are arranged in a one-to-one correspondence to facilitate the installation of the mounting roller 5 through the fixing plate 3, so as to facilitate the training and rehabilitation of the patient's lower limbs.

[0028] A rubber sleeve 6 is fitted onto the outer side of the mounting roller 5. A groove structure for mounting the mounting roller 5 is provided on the rear side of the lower end of the fixing plate 3. When the patient is in the initial rehabilitation training, he sits on the seat 1 and places his lower limbs on the outer side of the upper end of the rubber sleeve 6. At this time, the mounting roller 5 is fixedly installed in the groove structure on the rear side of the fixing plate 3 by bolts. The position of the mounting roller 5 is close to the seat 1 and the swing amplitude is small, which can reduce the intensity of rehabilitation training.

[0029] A gear 9 is provided at the upper end of the interior of the mounting plate 2, and a transmission assembly is provided on the outer side of the upper end of the gear 9. The transmission assembly includes a cylinder 7 and a gear plate 8. The cylinder 7 is installed on the outer side of the upper end of the mounting plate 2, and the output end of the cylinder 7 is connected to the gear plate 8 located inside the mounting plate 2. The lower end of the gear plate 8 is connected to the upper end of the gear 9, and the gear plate 8 is connected to the mounting plate 2 in a sliding manner.

[0030] The transmission rod 4 is connected to the mounting plate 2 by rotation. The cylinder 7 and the gear plate 8 have a good transmission effect on the gear 9 and the transmission rod 4, which facilitates the swinging of the fixed plate 3 on the outside of the mounting plate 2 via the transmission rod 4. When the cylinder 7 is activated, it extends and drives the gear plate 8 to slide inside the mounting plate 2. At this time, the gear plate 8 and the gear 9 mesh and rotate inside the mounting plate 2, which drives the transmission rod 4 to rotate synchronously. This causes the fixed plate 3 to move on the outside of the mounting plate 2, changing the height of the bottom of the fixed plate 3. The patient's lower limb can then be lifted by the mounting roller 5. The above steps are reversed to lower the patient's lower limb back to its original position. Repeating the above operations will cause the fixed plate 3 and the mounting roller 5 to swing back and forth for a certain period of time, thereby achieving the purpose of training and rehabilitating the patient's lower limb.

[0031] A positioning plate 10 is mounted on the outside of gear 9 via a bearing. The positioning plate 10 provides good installation and support for gear 9. A fixing pin 11 located on the outside of the mounting plate 2 is provided through the inside of the positioning plate 10. Two sets of prefabricated insertion holes 12 are provided through the inside of the positioning plate 10, and the size of the prefabricated insertion holes 12 is adapted to the size of the fixing pin 11. When the patient is undergoing later rehabilitation training, the fixing pin 11 is pulled out of the positioning plate 10. At this time, the fixing pin 11 is separated from the prefabricated insertion holes 12, and then the positioning plate 10 is pulled outward.

[0032] A rectangular structure is provided at one end of the transmission rod 4 near the gear 9, and the rectangular structure is connected to the gear 9 by a snap-fit ​​method. The positioning plate 10 drives the gear 9 to move outward at the same time. At this time, the gear 9 separates from the rectangular structure on the outside of the transmission rod 4. Then, the fixing pin 11 is inserted into another set of prefabricated holes 12 to fix the positioning plate 10.

[0033] Next, adjust the position of the mounting roller 5 to the lower front side of the fixing plate 3 and fix it with bolts. At this time, the patient can place the lower limb on the outer rear end of the rubber sleeve 6 and lift the lower limb to drive the fixing plate 3 and the transmission rod 4 to rotate. The transmission rod 4 is provided with a torsion spring 13 located in the mounting plate 2. At this time, the torsion spring 13 deforms and generates a force to restore the transmission rod 4 and the fixing plate 3 to their original position. Thus, the mounting roller 5 and the rubber sleeve 6 apply force to the patient's lower limb, thereby facilitating the improvement of the rehabilitation training effect of the patient's lower limb.

[0034] The technical features of the above embodiments can be combined in any way as long as there is no contradiction in the combination of these technical features. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
