One end of the first rope 13 is detachably connected to a counterweight 16, and one end of the second rope 14 is fixed with a pull ring 17. The opposite ends of the first rope 13 and the second rope 14 are detachably fixedly connected by a connecting pin 15. The first rope 13 and the second rope 14 are separable. The first rope 13 and the second rope 14 can pass between the first pulley 10 and the second pulley 12, which serve as limiting guides. The connecting pin 15 cannot pass between the first pulley 10 and the second pulley 12, ensuring that the counterweight 16 will not fall out between the first pulley 10 and the second pulley 12. During training, the patient can hold the pull ring 17 and slide it between the first pull rope 10 and the second pull rope 12 through the corresponding first pull rope 13 and second pull rope 14, thereby pulling the counterweight 16 up and down to exercise the patient's arm function and prevent or reduce symptoms of muscle atrophy and joint stiffness. The overall operation is simple, convenient and easy to learn.
[0029] As will be known to those skilled in the art regarding the above examples, when implementing the above technical solutions, the counterweight 16 has various weight specifications, and the counterweight 16 can be replaced according to the intensity requirements of the training.
[0030] As a technical optimization of this utility model, the top rod mechanism includes a rotating rod 18 rotatably connected to the top of the upright 1, and two guide pulleys 19 symmetrically rotate on the rotating rod 18. The guide pulleys 19 can guide the second pull rope 14. The rotating rod 18 can rotate to a right angle with the upright 1 and is positioned and fixed by matching fastening bolts.
[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, multiple rotating rods 18 can be provided, that is, a rotating rod 18 is provided at the top of the upright rod 1, and a rotating rod 18 is also provided at the top of the rotating rod 18.
[0032] As a technical optimization of this utility model, the top of the rotating rod 18 is provided with a socket, and a C-shaped plug 20 is provided for the socket. Upright rods 1 can be set on both sides of the patient. The rotating rods 18 on the two upright rods 1 can rotate to a right angle with the upright rods 1. After rotation, the two rotating rods 18 are set end to end against each other. At this time, the C-shaped plug 20 can be set to be inserted into the socket of the two rotating rods 18 to achieve the effect of connecting the two rotating rods 18.
[0033] As a technical optimization of this utility model, the bottom of the upright 1 is provided with a base plate, and two clamping plates 21 are slidably provided at the lower end of the upright 1. A bidirectional lead screw 22 is vertically rotatable on the side of the upright 1, and the two clamping plates 21 are respectively threaded onto the two ends of the bidirectional lead screw 22. The bidirectional lead screw 22 is made of a single rod with two sections of threads with different directions of rotation, namely one section of right-hand thread and one section of left-hand thread. When the bidirectional lead screw 22 rotates in different directions, the two clamping plates 21 can move closer or further apart. Through the setting of the two clamping plates 21, the edge of the bed can be clamped to achieve stable fixation of the upright 1.
[0034] As those skilled in the art will know from the above example, when implementing the above technical solution, the top of the bidirectional lead screw 22 is fitted with a rocker handle for rotation.
[0035] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to setting two clamping plates 21 and a bidirectional lead screw 22 to fix the upright 1, but also to setting a binding strap to bind and fix the upright 1.
[0036] In this invention, the working principle of the device is as follows:
[0037] When performing arm training for long-term bedridden patients, the upright bar 1 is placed on the side of the arm to be exercised and fixed. Then, the counterweight 16 is set up, and the first pull rope 13 and the second pull rope 14 are fixedly connected by the connecting pin 15. The first pull rope 13 and the second pull rope 14 are then placed between the first pulley 10 and the second pulley 12, with the sliding seat 11 installed during this process. This clamps and restricts the first pull rope 13 and the second pull rope 14 between the first pulley 10 and the second pulley 12. Then, training can begin. The patient can hold the pull ring 17 and slide the corresponding first pull rope 13 and the second pull rope 14 between the first pulley 10 and the second pulley 12, thereby pulling the counterweight 16 up and down to exercise the patient's arm function and prevent or alleviate symptoms of muscle atrophy and joint stiffness. The overall operation is simple, convenient and easy to learn.
[0038] In the above operation, the connecting pin 15 ensures that the counterweight 16 will not fall out between the first pulley 10 and the second pulley 12, preventing it from falling. Meanwhile, the upright 1 can be used as an IV stand when restricted. The crossbar 2 can be flexibly adjusted in height and forward / backward position, making it flexible and convenient to use.
[0039] Simultaneously, uprights 1 can be installed on both sides of the patient to facilitate simultaneous arm exercises. The training method can also be changed. After setting up the uprights 1 on both sides, both rotating rods 18 are rotated to a right angle with the uprights 1, and the two rotating rods 18 are positioned end-to-end against each other. C-shaped inserts 20 are used to connect the two rotating rods 18. Then, the two support seats 8 are rotated so that the first pulley 10 and the second pulley 12 are aligned with the axis of the guide pulley 19. Next, the two counterweights 16 are removed, and the two second pull ropes 14 are connected end-to-end using connecting pins 15. The two second pull ropes 14 are then passed around the corresponding guide pulley 19 and between the first pulley 10 and the second pulley 12. At this point, the patient can grasp the pull rings 17 with both hands and pull left, right, up, and down—one arm pulling down and the other arm raising—repeatedly to achieve the desired exercise effect.
[0040] Two guide pulleys 19 are symmetrically arranged on the rotating rod 18 to ensure that when the two uprights 1 are set in a mirror image, the second pull rope 14 can perform the same side guide wiring operation.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
