Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a lower limb exercise device for orthopedic nursing. Background Technology
[0002] Patients who suffer bone or joint injuries need to undergo surgery for treatment. However, the long-term bed rest required after treatment can cause the meridians at the surgical site to constrict. Therefore, regular exercise is necessary during the recovery period to aid in the body's recovery, which necessitates a lower limb exercise facility.
[0003] For example, the patent application CN220478050U discloses a lower limb exercise mechanism for orthopedic care, belonging to the field of medical device technology. It includes a base, with a support column one at the upper end of the base, a second support column and a fixing block fixedly connected to the upper end of the base, an electric cylinder fixedly connected to the base, and a foot pedal located on the second support column, between the second support column and the fixing block. This patent claims to solve the problems of existing lower limb exercise mechanisms for orthopedic care being unsuitable for orthopedic patients with difficulty standing, limiting the applicable population, and failing to adjust the patient's posture according to different heights and body types, thus reducing the patient's comfort during lower limb exercise, hindering injury care and rehabilitation, and significantly reducing practicality.
[0004] However, the lower limb exercise mechanism mentioned in the patent is limited to electrically driven exercise and cannot be used for non-electrically driven rehabilitation training at the same time. In addition, the exercise method cannot be changed, resulting in poor functionality. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:
[0023] A lower limb exercise mechanism for orthopedic nursing includes a base plate 101. Fixing holes 102 are provided at the four corners of the top of the base plate 101. A support block 103 is fixedly installed in the middle of the top of the base plate 101. A drive mechanism 104 is provided at the top of the support block 103. The drive mechanism 104 includes a drive box 105. The support block 103 is fixedly installed at the bottom of the drive box 105. A control button 201 is fixedly installed at the top of the drive box 105. A driving mechanism 202 is provided on the left and right sides of the drive box 105.
[0024] The above solution allows the entire system to be supported by a base plate, fixed by mounting holes, components to be installed via a drive box, and the drive motor to be controlled via control buttons.
[0025] In this embodiment, preferably, the driving mechanism 104 further includes a driving chamber 203, in which a driving motor 204 is fixedly installed, and driving shafts 205 are fixedly installed at both ends of the driving motor 204.
[0026] The above solution allows for the installation of a drive motor in the drive compartment, which in turn drives the drive shaft to rotate, providing power for exercise.
[0027] In this embodiment, preferably, the drive shaft 205 passes through the drive box 105 and is fixedly installed with a first locking block 206. A first screw 301 is fixedly installed at the front end of the first locking block 206, and a first nut 302 is fixedly installed on the first screw 301.
[0028] With the above scheme, the connecting rod can be installed on the first locking block by connecting the first nut and the first screw.
[0029] In this embodiment, preferably, the driving mechanism 202 includes a connecting rod 303, with connecting blocks 304 fixedly installed at both ends of the connecting rod 303. A slot 305 is provided in the middle of the connecting block 304, and a first slot 206 and a second slot 306 are fixedly installed in the slot 305.
[0030] The above scheme allows the connecting block to be locked onto the drive shaft by connecting it to the first locking block via the slot, and the connecting block to be locked onto the drive rod by connecting it to the second locking block via the slot.
[0031] In this embodiment, preferably, the second locking block 306 is fixedly installed at the front end of the driving rod 401, the front end of the second locking block 306 is fixedly installed with a second screw 402, and the second screw 402 is fixedly installed with a second nut 403.
[0032] With the above solution, the foot pedal can be driven by the driving rod, and the driving rod can be fixed to the connecting rod by installing the second screw and the second nut.
[0033] In this embodiment, preferably, a third screw 404 is fixedly installed on the right side of the driving rod 401, a limit nut 405 is fixedly installed on the third screw 404, and a bearing assembly 406 is fixedly installed on the outside of the driving rod 401.
[0034] The above scheme allows the foot pedal to be fixed in place by installing the third screw and the limit nut, while the bearing assembly allows the foot pedal to rotate.
[0035] In this embodiment, preferably, the bearing assembly 406 is fixedly installed inside the rotating groove 501, the rotating groove 501 is opened in the middle of the foot pedal 502, the top of the foot pedal 502 is fixedly installed with anti-slip teeth 503, and the left and right sides of the foot pedal 502 are fixedly installed with hooks 504.
[0036] The above solution allows the foot pedal and bearing assembly to be installed via the rotating groove. The foot pedal supports the patient's feet, while the anti-slip teeth increase friction and prevent the feet from slipping off. The hooks allow for strapping to secure the patient's feet.
[0037] In this embodiment, a lower limb exercise mechanism for orthopedic nursing is used such that medical staff fix the base plate 101 to the ground through the fixing holes 102. The patient is then seated in a wheelchair or stool, with their feet placed on the anti-slip teeth 503. The feet are secured with straps using hooks 504. The drive motor 204, a dual-axis stepper motor with drive shafts 205 at both ends, is controlled by the control button 201. When the drive motor 204 rotates the drive shafts 205, the first locking block 206 drives the connecting rod 303 to rotate. The rotation of the connecting rod 303, in turn, drives the driving rod 401 to rotate around the rotation axis via the second locking block 306. This causes the user's feet to rotate around the rotation axis, changing their position as they rotate. This allows the patient's legs to be stretched and exercised. When the feet rotate on the pedals 502, the pedals 502 rotate on the drive rod 401 via the bearing assembly 406, thereby causing the joints of the feet to move on the pedals 502. This exercise method can help the patient extend their lower limbs. At the same time, by disassembling the first nut 302, the connecting rod 303 can be reversed through the first locking block 206 and the locking slot 305, so that the positions of the two sets of pedals 502 are opposite. At this time, the feet are fixed and driven by the drive motor 204, which can make the patient perform walking-like exercises, thereby helping the patient recover. When the patient recovers well, the medical staff will turn off the power to the drive motor 204. At this time, the patient can use their own extension to pedal the pedals 502 in a cycling manner, so that the patient can carry out rehabilitation training.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
