Description

Technical Field

[0001] This utility model relates to the field of medical exercise equipment technology, and in particular to a cardiovascular medicine exercise device that can be used in hospital beds. Background Technology

[0002] In the cardiology department, postoperative patients need to engage in appropriate limb exercises to improve blood circulation, strengthen their constitution, and prevent complications such as thrombosis. Exercise not only helps restore patients' physical strength and mobility but also promotes postoperative recovery and reduces hospital stay.

[0003] However, some patients are unable to get out of bed and perform routine limb movements due to postoperative weakness, disease limitations, or other reasons. In such cases, prolonged bed rest not only further weakens muscle strength but may also lead to poor blood circulation, increasing the risk of thrombosis, thereby delaying the recovery process and potentially causing more postoperative complications.

[0004] To address the aforementioned issues, we propose a leg exercise device that can be used in hospital beds, designed to help patients perform effective leg exercises while bedridden, ensuring safety while achieving rehabilitation results. Utility Model Content

[0005] This utility model discloses a cardiovascular medicine exercise device that can be used in hospital beds, aiming to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cardiovascular medicine exercise device applicable to hospital beds includes a frame, the frame being configured as a U-shaped structure, with two upright plates symmetrically fixedly connected to the frame, each upright plate having an adjustment groove, and fixing holes symmetrically and equidistantly provided on both sides of the adjustment groove on the upright plates, and a driving mechanism provided between the two upright plates.

[0008] The drive mechanism includes two mounting plates, each mounted on a side of two vertical plates that are far apart. Each mounting plate is connected to a corresponding fixing hole by screws. Each mounting plate is provided with a bearing seat, and a rotating shaft is connected between the two bearing seats. Mounting sections are equidistantly arranged on the outer side of the rotating shaft. Each mounting section has a symmetrically arranged plane and a through hole inside. A drive motor is fixedly connected to one of the mounting plates, and the output end of the drive motor is connected to the rotating shaft.

[0009] Each of the aforementioned installation sections is equipped with an adjustment mechanism for exercise.

[0010] In a preferred embodiment, the adjusting mechanism includes a first rotating plate and a second rotating plate. Both the first and second rotating plates have mating arc grooves inside, which are used in conjunction with corresponding mounting sections. The first rotating plate has a threaded hole inside, and the second rotating plate has an insertion hole. A fixing bolt connects the insertion hole and the threaded hole. The first and second rotating plates are connected by the fixing bolt. The fixing bolt, by engaging with the through hole, the insertion hole, and the threaded hole, allows the first and second rotating plates to rotate synchronously with the rotating shaft.

[0011] In a preferred embodiment, the adjusting mechanism further includes a groove symmetrically formed on both sides of the first rotating plate and the second rotating plate. A slide rod is slidably connected inside the groove, and a rotating block is rotatably connected to the outside of the slide rod. A suspension rope is fixedly connected to the bottom of the rotating block.

[0012] In a preferred embodiment, the frame has a through groove, and the bottom of the suspension rope extends through the through groove into the interior of the frame and is connected to a strap. The straps are all connected to the patient's leg by Velcro.

[0013] In a preferred embodiment, clamping mechanisms are provided on both sides of the frame. Each clamping mechanism includes four optical rods, which are symmetrically and slidably connected in pairs inside the frame. A clamping plate is fixedly connected between one end of each pair of optical rods. A lead screw is rotatably connected to each clamping plate and located between the corresponding two optical rods. The lead screws extend to the outside of the frame and are threadedly connected to it.

[0014] In a preferred embodiment, a handle is fixedly connected to one end of the lead screw, and a lock nut is threaded onto the outer side of the lead screw.

[0015] In a preferred embodiment, the bottom of the frame is symmetrically connected with rollers.

[0016] The cardiovascular medicine exercise device provided by this utility model, which can be used in hospital beds, has the following advantages:

[0017] This invention allows for easy movement of the device via rollers. Rotating the lead screw secures the clamping plate to the hospital bed, thus fixing the device in place. Adjusting the position of the mounting plate controls the height of the rotating shaft. A drive motor rotates the shaft, and fixing bolts secure the first and second rotating plates to their corresponding mounting sections. As the shaft rotates, the sliding rod and rotating block slide within the groove, and the cam-shaped combination of the first and second rotating plates moves the rotating block up and down. By attaching the strap to the patient's lower leg, the movement of the rotating plates allows for the up-and-down movement of the patient's lower leg, achieving an exercise effect. This design not only facilitates leg exercises in bed and promotes blood circulation but also effectively avoids exercise risks. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] This utility model discloses a cardiovascular medicine exercise device that can be used in hospital beds.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cardiovascular medicine exercise device applicable to hospital beds includes a frame 1, with rollers 27 symmetrically connected to the bottom of the frame 1. The frame 1 is configured as a U-shaped structure, and two upright plates 2 are symmetrically fixedly connected to the frame 1. Each upright plate 2 has an adjustment groove 3, and fixed holes 4 are symmetrically and equidistantly provided on both sides of the adjustment groove 3 on the upright plate 2. A driving mechanism is provided between the two upright plates 2.

[0029] The drive mechanism includes two mounting plates 5, each mounted on a side of two vertical plates 2 that are far apart. Each mounting plate 5 is connected to a corresponding fixing hole 4 by screws. Each mounting plate 5 is provided with a bearing seat 6. A rotating shaft 7 is connected between the two bearing seats 6. Mounting sections 8 are equidistantly arranged on the outer side of the rotating shaft 7. Each mounting section 8 has a symmetrically arranged plane and a through hole 9 inside. A drive motor 10 is fixedly connected to one of the mounting plates 5. The output end of the drive motor 10 is connected to the rotating shaft 7.

[0030] Each of the corresponding installation sections 8 is equipped with an adjustment mechanism for exercise;

[0031] In this embodiment, the device can be easily moved by the rollers 27, and the height of the rotating shaft 7 can be controlled by controlling the position of the mounting plate 5 on the upright plate 2. Then, the rotating shaft 7 is driven to rotate by the drive motor 10, and the rotation of the rotating shaft 7 achieves the driving purpose.

[0032] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in a preferred embodiment, the adjusting mechanism includes a first rotating plate 11 and a second rotating plate 12. Both the first rotating plate 11 and the second rotating plate 12 have mating arc grooves 13 inside, which mate with corresponding mounting sections 8. The first rotating plate 11 has a threaded hole 14 inside, and the second rotating plate 12 has an insertion hole 15. A fixing bolt 16 connects the insertion hole 15 and the threaded hole 14. The first rotating plate 11 and the second rotating plate 12 are connected by the fixing bolt 16, which passes through the through hole 9, the insertion hole 15, and the threaded hole. 14 is used in conjunction to allow the first rotating plate 11 and the second rotating plate 12 to rotate synchronously with the rotating shaft 7. The adjustment mechanism also includes a groove 17, which is symmetrically opened on both sides of the first rotating plate 11 and the second rotating plate 12. A slide rod 18 is slidably connected inside the groove 17, and a rotating block 19 is rotatably connected to the outside of the slide rod 18. A suspension rope 20 is fixedly connected to the bottom of the rotating block 19. A through groove 28 is opened on the frame 1. The bottom of the suspension rope 20 extends into the inside of the frame 1 through the through groove 28 and is connected to a strap 21. The straps 21 are all connected to the patient's leg by Velcro.

[0033] In this embodiment: The first rotating plate 11 and the second rotating plate 12 are installed on the mounting section 8 at the corresponding positions by fixing bolts 16. Then, the rotation of the rotating shaft 7 can drive the first rotating plate 11 and the second rotating plate 12 to rotate. As the first rotating plate 11 and the second rotating plate 12 rotate, the slide rod 18 and the rotating block 19 can slide inside the groove 17. The combination of the first rotating plate 11 and the second rotating plate 12 is cam-shaped. The rotation of the first rotating plate 11 and the second rotating plate 12 can drive the rotating block 19 to move up and down. When the strap 21 is tied to the patient's lower leg, the rotation of the first rotating plate 11 and the second rotating plate 12 can drive the patient's lower leg to move up and down to achieve the exercise effect.

[0034] Furthermore, the aforementioned technical means can also be used to allow the two sets of first rotating plates 11 and second rotating plates 12 to be installed symmetrically, allowing the patient's feet to rise and fall alternately. If the two sets of first rotating plates 11 and second rotating plates 12 are installed in the same posture, the patient's feet can be controlled to rise and fall simultaneously, so as to achieve different training methods according to different patients.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, in a preferred embodiment, clamping mechanisms are provided on both sides of the frame 1. The clamping mechanism includes four light rods 22, which are symmetrically slidably connected in pairs inside the frame 1. A clamping plate 23 is fixedly connected between one end of each pair of light rods 22. A lead screw 24 is rotatably connected to the clamping plate 23 between the corresponding two light rods 22. The lead screw 24 extends to the outside of the frame 1 and is threadedly connected thereto. A handle 25 is fixedly connected to one end of the lead screw 24, and a locking nut 26 is threadedly connected to the outside of the lead screw 24.

[0036] In this embodiment, by rotating the lead screw 24, the clamping plate 23 can be moved so that the two clamping plates 23 can be clamped on the patient's bed, thus fixing the device to the bed for use.

[0037] Working Principle: The device can be easily moved using rollers 27. Rotating the lead screw 24 controls the movement of the clamping plates 23, allowing them to clamp onto the patient's bed, thus fixing the device in place. Adjusting the position of the mounting plate 5 on the upright plate 2 controls the height of the rotating shaft 7. The drive motor 10 drives the rotating shaft 7 to rotate, achieving the driving purpose. Fixing bolts 16 are used to install the first rotating plate 11 and the second rotating plate 12 onto their corresponding mounting sections 8. When the rotating shaft 7 rotates, it drives the first rotating plate 11 and the second rotating plate 12 to rotate together. As the first rotating plate 11 and the second rotating plate 12 rotate, the sliding rod 18 and the rotating block 19 can slide within the groove 17. Since the combination of the first rotating plate 11 and the second rotating plate 12 is cam-shaped, their rotation drives the rotating block 19 to move up and down. By attaching the strap 21 to the patient's lower leg, the rotation of the first rotating plate 11 and the second rotating plate 12 allows the patient's lower leg to move up and down, achieving an exercise effect.

[0038] Furthermore, the two sets of first rotating plates 11 and second rotating plates 12 can be installed symmetrically, allowing the patient's feet to rise and fall alternately for alternating exercise. If the two sets of first rotating plates 11 and second rotating plates 12 are installed in the same manner, the patient's feet can be controlled to rise and fall synchronously to meet the exercise needs of different patients.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
