Description

Technical Field

[0001] This utility model relates to the field of joint exercise instruments, specifically to an orthopedic joint exercise instrument. Background Technology

[0002] Orthopedic joint exercise equipment, also known as CPM machine, can simulate the natural movement of human joints. Through slow, continuous and passive joint movements, it promotes the circulation of synovial fluid, improves the nutritional supply to articular cartilage, and prevents joint adhesions and stiffness.

[0003] The instrument mainly consists of a power system, a transmission device, and a joint movement support. For example, when rehabilitating a patient's arm, the patient's arm needs to be placed on the instrument's placement plate. The instrument controls the placement plate to slowly rotate upwards, and then assists in bending the patient's arm, thereby helping the patient promote blood circulation in the joint and achieve the rehabilitation effect.

[0004] However, the length of the placement plate in some existing joint exercise devices is fixed. Since the arm lengths of different patients are different, it is difficult to adjust it accordingly. If some patients have longer arms, part of their arms will be exposed outside the placement plate during rehabilitation, which will cause discomfort to the patients and affect subsequent rehabilitation. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an orthopedic joint exercise device to solve the problem mentioned in the background art that the placement plate of existing orthopedic joint exercise devices has a fixed length, making it difficult to adjust it according to the length of different patients' arms.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An orthopedic joint exercise device includes a mounting frame and a connecting plate. The connecting plate is fixedly mounted on the mounting frame. The device also includes a load-bearing plate, an extension plate, a fixing component, and a support component. The load-bearing plate is rotatably mounted on the side of the connecting plate via a rotating shaft, and a groove is formed on the surface of the load-bearing plate. The extension plate is slidably mounted within the groove of the load-bearing plate. Two fixing components are provided, both mounted on the mounting frame and the connecting plate, for fixing the extension plate after it has slid completely. The support component is mounted on the load-bearing plate for supporting the groove of the load-bearing plate after the extension plate has slid completely.

[0010] Furthermore, the fixing component includes a connecting wire, a fixing block, and a placement block. One end of the connecting wire is fixedly installed on the side of the connecting plate, the fixing block is fixedly installed on the other end of the connecting wire, and the placement block is fixedly installed on the side of the mounting bracket.

[0011] Furthermore, the support assembly includes bolts and a support plate. The side of the load-bearing plate has a threaded hole, and the bolt is threadedly installed in the threaded hole. The side of the support plate has a threaded hole, and the bolt is threadedly installed in the threaded hole of the support plate. The support plate is slidably installed through the extension plate.

[0012] In order to fix the extension plate to the load-bearing plate after it has slid through, the extension plate is further provided with fixing grooves on both sides, the load-bearing plate is provided with several fixing grooves on both sides, and the fixing block is adapted to the fixing grooves.

[0013] Because the fixing block is installed on the side of the mounting bracket via the connecting line, the fixing block can be inserted into the placement block when no fixing is required. Furthermore, the side of the placement block is provided with a placement groove that is compatible with the fixing block.

[0014] In order to support the bottom of the load-bearing plate when it is placed horizontally, two support rods are further fixedly installed on the side of the mounting bracket at an angle, and when the load-bearing plate is in a horizontal position, the bottom of the load-bearing plate is in contact with the top of the support rods.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an orthopedic joint exercise device with the following beneficial effects:

[0017] 1. In this utility model, when exercising different patients, the extension plate can be slidably installed on the load-bearing plate according to the length of the patient's arm, so that the patient's forearm can be fully placed, and after placement, the extension plate can be fixed on the load-bearing plate by the fixing component so that it will no longer slide.

[0018] 2. In this utility model, after the extension plate has slid completely, since the surface of the load-bearing plate has a groove, in order to prevent the patient's arm from dangling in the groove, the groove can be supported by a support component, and the patient's arm can rest on the support plate.

[0019] Therefore, this orthopedic joint exercise device, through the cooperation between the load-bearing plate, extension plate, fixation component and support component, can adjust the position of the extension plate according to the length of different patients' arms, so as to fully support and place the patient's arm. Compared with fixed installation on the placement plate, it is more flexible and can be adjusted. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Please see Figures 1 to 4 An orthopedic joint exercise device includes a mounting frame 1 and a connecting plate 2. The connecting plate 2 is fixedly mounted on the mounting frame 1. The device also includes a load-bearing plate 3, an extension plate 4, a fixing component, and a support component. The load-bearing plate 3 is rotatably mounted on the side of the connecting plate 2 via a rotating shaft, and a groove is formed on the surface of the load-bearing plate 3. The extension plate 4 is slidably mounted in the groove of the load-bearing plate 3. Two fixing components are provided, both of which are set on the mounting frame 1 and the connecting plate 2, for fixing the extension plate 4 after it has slid completely. The support component is set on the load-bearing plate 3 for supporting the groove of the load-bearing plate 3 after the extension plate 4 has slid completely.

[0027] like Figure 2 and Figure 3As shown, during patient rehabilitation, the patient first places their arm on the connecting plate 2, and then places their forearm on the extension plate 4. The sliding extension plate 4 can be adjusted according to the forearm length of different patients. The extension plate 4 slides on the load-bearing plate 3. Because both sides of the extension plate 4 and the load-bearing plate 3 have fixing grooves, and the fixing block 6 is adapted to the fixing grooves, the position of the fixing groove of the sliding extension plate 4 relative to a certain fixing groove of the load-bearing plate 3 allows the patient's forearm to be fully placed. After placement, the extension plate 4 is fixed to the load-bearing plate 3 by a fixing assembly, which includes a connecting plate 4. The connecting wire 5, fixing block 6, and placement block 7 are used. One end of the connecting wire 5 is fixedly installed on the side of the connecting plate 2, the fixing block 6 is fixedly installed on the other end of the connecting wire 5, and the placement block 7 is fixedly installed on the side of the mounting bracket 1. Specifically, the fixing block 6 is inserted into the fixing groove of the extension plate 4 and the load-bearing plate 3 for fixation. It should be added that a motor 11 is installed on the side of the connecting plate 2. The output end of the motor 11 is coaxially connected to the rotating shaft. Under the drive of the motor 11, the load-bearing plate 3 and the extension plate 4 rotate synchronously, thereby causing the patient's forearm to bend slowly and help with rehabilitation. The patient's forearm can be fixed on the extension plate 4 with Velcro.

[0028] Because the mounting bracket 1 has two support rods 10 fixedly installed on its side at an angle, and when the load-bearing plate 3 is in a horizontal position, the bottom end of the load-bearing plate 3 contacts the top end of the support rod 10, and the side of the placement block 7 has a placement groove that matches the fixing block 6, the load-bearing plate 3 can be supported by the support rods 10 after being rotated to a horizontal position when there is no need to rotate. At this time, there is no need to fix it or when transporting it, the fixing block 6 can be inserted into the slot of the placement block 7 for placement.

[0029] like Figure 4 As shown, after the extension plate 4 slides on the load-bearing plate 3, the patient's arm will be suspended in the air due to the groove on the load-bearing plate 3. Therefore, the patient's forearm can be supported by the support assembly, which includes a bolt 8 and a support plate 9. The side of the load-bearing plate 3 has a threaded hole, and the bolt 8 is threaded into the threaded hole. The side of the support plate 9 also has a threaded hole, and the bolt 8 is threaded into the threaded hole of the support plate 9. The support plate 9 is slidably installed inside the extension plate 4. Specifically, when the extension plate 4 slides on the load-bearing plate 3, since one end of the support plate 9 is fixed to the side of the load-bearing plate 3 and the support plate 9 can slide inside the extension plate 4, the groove that is exposed after the extension plate 4 has slid is "filled" by the support plate 9, so that the patient's forearm can be placed on the support plate 9.

[0030] Working principle: When this orthopedic joint exercise instrument is used for patient rehabilitation, the patient's arm is first placed on the connecting plate 2 and the extension plate 4. The extension plate 4 is slid on the load-bearing plate 3 according to the length of the patient's arm. During the sliding process, the support plate 9 can be located in the groove of the load-bearing plate 3, so that the patient's arm can be supported by the support plate 9. After the sliding is completed, the fixing block 6 is inserted into the fixing groove of the extension plate 4 and the load-bearing plate 3 to fix it. After fixing, the motor 11 is started. The output end of the motor 11 drives the load-bearing plate 3 and the extension plate 4 to rotate the patient's forearm, thereby performing rehabilitation training for the patient.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
