Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rehabilitation nursing, and specifically relates to a traction device. Background Art
[0002] In order to improve the recovery speed of patients who have undergone shoulder joint surgery, patients need to frequently perform flexion exercises in rehabilitation exercises, including upper limb traction exercises. When performing upper limb traction exercises, patients are required to sit and hold the handles of the upper limb traction device with both hands, with the operated arm at the bottom and the healthy arm at the top. Pull the handle with the healthy hand to drive the operated arm up, straighten the elbow on the operated side and relax the shoulder as much as possible. When the operated arm is raised to the maximum, maintain it for 10 seconds to ensure the effect of the exercise and then slowly return to its original position. Rest for 10 seconds and repeat the above actions 10 times. When performing upper limb traction exercises, traction exercises are mainly performed by the patient holding the handles with both hands. However, since the patient's grip strength on the affected hand is relatively small when he has not recovered, the handle is easily slipped out of the hand during the exercise, resulting in unsatisfactory traction effect and affecting the recovery speed.

[0018] In this embodiment: it includes a seat 1. When performing upper limb traction exercises, the patient needs to sit on the seat 1. Support frames 2 are provided on both sides of the top of the seat 1. A connecting groove 21 is provided on the top of the support frame 2. The support frame 2 is perpendicular to the seat 1, and the positions of the two support frames 2 are opposite. The support frame 2 is fixedly connected to the seat 1. A movable frame 3 is provided between the two support frames 2. The movable frame 3 is parallel to the seat 1. The two ends of the movable frame 3 are respectively connected to the two support frames 2. The two ends of the movable frame 3 are slidably connected to the inner side of the connecting groove 21. Through the sliding of the movable frame 3 and the connecting groove 21, the height of the movable frame 3 can be adjusted according to the patient's body shape. The tops of the two ends of the movable frame 3 are rotatably connected with threaded rods 32. The tops of the support frames 2 are provided with threaded grooves 22. The screws The threaded rod 32 is threadedly connected to the thread groove 22. Since the threaded rod 32 is threadedly connected to the thread groove 22, the movable frame 3 can be moved up and down by rotating the threaded rod 32, so as to achieve the purpose of adjusting the height of the movable frame 3. Two connecting plates 34 are provided at the bottom of the movable frame 3. The connecting plates 34 are fixedly connected to the movable frame 3, and the positions of the two connecting plates 34 are opposite. There is a gap between the two connecting plates 34, and a pulley 341 is rotatably connected between the two connecting plates 34. The pulley 341 is rotatably connected to the inner sides of the two connecting plates 34 through a connecting shaft. A traction belt 4 is provided on the outer side of the pulley 341. By pulling one end of the traction belt 4, the patient's arm can be pulled upward, and the connecting plate 34 can be rolled The pulling of the traction belt 4 can be made smoother and more labor-saving. Handles 5 are provided at both ends of the traction belt 4. The handles 5 are fixedly connected to the traction belt 4. Two elastic ropes 52 are slidably connected inside the handle 5. Both ends of the two elastic ropes 52 are located outside the handle 5. The ends of the two elastic ropes 52 are connected by an arc-shaped wrist ring 53. By staggering the two arc-shaped wrist rings 53 and making the patient's wrists located between the two arc-shaped wrist rings 53, the two arc-shaped wrist rings 53 can be respectively put on both sides of the patient's wrists. Through the connection of the elastic ropes 52, the two arc-shaped wrist rings 53 are pulled against each other, and the two arc-shaped wrist rings 53 will be subjected to an inward force at the same time, thereby achieving the purpose of limiting the patient's hands. Guide shafts 5 are provided at both ends of the handle 5. 5. The guide shaft 55 is located between the elastic rope 52 and the handle 5. The elastic rope 52 can be supported by the guide shaft 55.

The patient's hand can be limited by the handle 5, the elastic rope 52 and the arc-shaped bracelet 53 to avoid the patient's hand being separated from the handle 5 due to weak grip, resulting in an unsatisfactory traction effect, which is beneficial to ensuring the effect of traction exercise and improving the patient's recovery speed. At the same time, the sliding of the elastic rope 52 and the handle 5 can avoid the patient's arm swinging, resulting in excessive pressure on the wrist by the arc-shaped bracelet 53 on one side of the patient, causing discomfort to the patient.
[0019] A connecting seat 31 is provided at the top of both ends of the movable frame 3, and a threaded rod 32 is rotatably connected to the connecting seat 31; the connecting seat 31 is fixedly connected to the movable frame 3, and through the rotatable connection between the threaded rod 32 and the connecting seat 31, the situation in which interference with the rotation of the threaded rod 32 due to the fixed direction of the movable frame 3 can be avoided.
[0020] An adjusting disk 33 is provided at the top of the threaded rod 32, and a gear 331 is provided on the adjusting disk 33. The outer sides of the two gears 331 are meshedly connected with a toothed belt 332, and an adjusting rod 333 is provided on the outer side of the adjusting disk 33. The adjusting disk 33 is fixedly connected to the threaded rod 32, so the adjusting disk 33 and the threaded rod 32 rotate synchronously. Through the meshing connection of the two gears 331 and the toothed belt 332, the two threaded rods 32 can rotate synchronously, so that the height of both ends of the movable frame 3 can be adjusted at the same time.
[0021] A through slot 51 is provided on the handle 5, and an elastic rope 52 is slidably connected to the inner side of the through slot 51; when the patient's arm swings, the movement of the elastic rope 52 and the through slot 51 can prevent the arc-shaped bracelet 53 on one side of the patient from exerting excessive pressure on the wrist and causing discomfort to the patient.
[0022] Both ends of the handle 5 are provided with a fixing seat 54 , and the guide shaft 55 is rotatably connected to the fixing seat 54 ; the guide shaft 55 can be supported by the fixing seat 54 so that it is rotatably connected to the end of the handle 5 .
[0023] The working principle and use process of the utility model are as follows: when in use, first, the threaded rod 32 is rotated to make the movable frame 3 move up and down, so as to achieve the purpose of adjusting the height of the movable frame 3 and make the height of the movable frame 3 adapt to the patient's body shape, and then the two arc-shaped bracelets 53 are staggered so that the inner arc surfaces of the two arc-shaped bracelets 53 are opposite to each other, and then the patient passes his hand through the position between the two arc-shaped bracelets 53 and holds the handle 5 so that the patient's wrist is located between the two arc-shaped bracelets 53, so that the two arc-shaped bracelets 53 can be respectively put on both sides of the patient's wrist, and through the connection of the elastic rope 52, the two arc-shaped bracelets 53 are pulled against each other, and the two arc-shaped bracelets 53 will be subjected to inward force at the same time, so as to achieve the purpose of limiting the patient's hand, and after the two hands hold the two handles 5 respectively, the traction belt 4 can be pulled by the healthy hand to pull the affected arm to perform upper limb traction exercise.
