DETAILED DESCRIPTION

[0033] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 11 The present invention provides a technical solution: a sports rehabilitation device for limb injuries, comprising a moving seat 1, a universal wheel 11 for horizontal movement is arranged below the moving seat 1, an adjustment frame 3 is installed above the moving seat 1, the height of the adjustment frame 3 is adjustable, and a seat plate 39 is arranged above the adjustment frame 3;

[0035] The height of the adjustment frame 3 is adjustable, so that some patients with mild limb injuries, that is, patients can sit down with the help of medical staff or crutches. These patients can adjust the adjustment frame 3 to a height suitable for themselves according to their height and body shape, so that the patients can sit on the seat board 39 comfortably and conveniently.

[0036] A thigh positioning frame 4 is provided on one side of the adjustment frame 3, and the thigh positioning frame 4 can be extended and retracted according to the patient's body shape. A calf positioning frame 6 is provided on the side of the thigh positioning frame 4 away from the adjustment frame 3, and the thigh positioning frame 4 and the calf positioning frame 6 fix the patient's thigh and calf respectively.

[0037] The thigh positioning frame 4 is rotatably connected to the adjustment frame 3 and the calf positioning frame 6 respectively;

[0038] The thigh positioning frame 4 fixes the patient's thigh part, and the calf positioning frame 6 fixes the patient's calf part. By adjusting the mutual rotation structure between the frame 3, the thigh positioning frame 4 and the calf positioning frame 6, the patient's legs are driven to bend, thereby performing postoperative rehabilitation training for the knee joint.

[0039] A rotating plate 8 is provided below the thigh positioning frame 4 , and the rotating plate 8 drives the thigh positioning frame 4 to flip, and the calf positioning frame 6 follows the thigh positioning frame 4 to flip, so as to achieve the bending of the patient's legs.

[0040] Through the structure of the rotating plate 8, the thigh positioning frame 4 is controlled to rotate, and the calf positioning frame 6 is made to rotate accordingly. After the two fix the patient's thigh and calf respectively, the controllable movement between the two controls the patient's leg to bend, and the bending angle can also be adjusted as needed, which is suitable for patients in different recovery stages.

[0041] The upper two sides of the movable seat 1 are respectively fixedly connected with the bracket 2, the two sides of the adjusting frame 3 are respectively fixedly connected with the connecting rod 31, the outer end of the connecting rod 31 is fixedly connected with the lifting block 32, the lifting block 32 is arranged in the bracket 2, and the lifting block 32 is vertically slidably connected with the bracket 2, and a plurality of card slots 21 are respectively arranged on the inner walls of the two sides of the bracket 2, and the card slots 21 are vertically and evenly distributed in the bracket 2, and the two sides of the lifting block 32 are slidably connected with the card column 33, and the card column 33 is fixedly engaged with the card slot 21, and a first spring 34 is arranged on the inner side of the card column 33, one end of the first spring 34 is fixedly connected with the card column 33, and the other end of the first spring 34 is fixedly connected with the inner wall of the lifting block 32.

[0042] The lifting block 32 slides up and down in the bracket 2. After the lifting block 32 slides to a suitable height, the elastic force of the first spring 34 causes the clamping column 33 to engage with the clamping slot 21, and the adjustment frame 3 is fixed at this height, so that patients with moderate to mild illness can adjust to a height that is convenient for sitting down, while increasing the comfort of the patients.

[0043] A first connecting rope 35 is also fixedly connected to the inner side of the clamping column 33, and the other end of the first connecting rope 35 passes through the connecting rod 31, and the end of the first connecting rope 35 passes through the connecting rod 31 and is fixedly connected to the sliding column 36, and the sliding column 36 is sleeved on the outer side of the connecting rod 31 and is slidably connected thereto, and a second spring 38 is provided on the side of the sliding column 36 away from the lifting block 32, one end of the second spring 38 is fixedly connected to the sliding column 36, and the other end of the second spring 38 is fixedly connected to the outer wall of the adjusting frame 3, and a protective cover 37 is sleeved on the outer side of the second spring 38, and the protective cover 37 completely covers the outer side of the second spring 38, and the protective cover 37 covers part of the sliding column 36, and the protective cover 37 is fixedly connected to the outer wall of the adjusting frame 3.

[0044] The patient can first move the adjustment frame 3 to the highest point in the bracket 2, so that the patient can sit down. At this time, the sliding column 36 is pulled inward, so that the sliding column 36 drives the first connecting rope 35 to retract inward, so that the outer end of the first connecting rope 35 pulls the clamping column 33 to retract into the lifting block 32. At this time, the lifting block 32 slides vertically downward along the bracket 2. At the same time, the patient releases the sliding column 36 immediately after pulling the sliding column 36. Under the elastic force of the second spring 38, the sliding column 36 is reset, and the first connecting rope 35 loses the restraining force on the clamping column 33. Under the elastic force of the first spring 34, the clamping column 33 pops out again and is inserted into the adjacent clamping groove 21 below. The operation is repeated many times to adjust the height of the seat board 39. The height of the seat board 39 can also be adjusted before sitting down, which can be selected according to the patient's recovery level.

[0045] The structure of the protective cover 37 prevents the second spring 38 from leaking out, and prevents the hand from being pinched by the second spring 38 during the sliding process of the sliding column 36 .

[0046] A groove is provided above the adjusting frame 3, a through hole is provided in the middle of the adjusting frame 3 and completely penetrates the adjusting frame 3, a cylinder 310 is provided in the through hole of the adjusting frame 3, the cylinder 310 is fixed on the movable seat 1, the adjusting frame 3 is vertically slidably connected with the outer wall of the cylinder 310 through the through hole, the piston rod of the cylinder 310 penetrates into the top of the adjusting frame 3, the seat plate 39 is provided at the end of the piston rod of the cylinder 310, the bottom of the seat plate 39 is rotatably connected with the piston rod, and the seat plate 39 is engaged with the groove above the adjusting frame 3.

[0047] For a seriously ill patient, that is, a patient whose legs cannot touch the ground at all, or whose legs are injured, the medical staff or accompanying staff move the seat board 39 to the highest position through the cylinder 310, and carry the patient's legs flatly to the seat board 39. At this time, the patient's legs face the outside of the movable seat 1. After the seat board 39 supports the patient, the seat board 39 is rotated to move the patient's legs to the top of the thigh positioning frame 4, and the cylinder 310 is activated to lower the seat board 39 into the adjustment frame 3. At this time, the patient's legs are placed on the thigh positioning frame 4.

[0048] By raising the seat 39 separately and being able to rotate the structure, the accompanying personnel can conveniently carry the patient who is difficult to move from the outward side of the seat 39 to the seat 39, avoiding carrying the patient above the mobile seat 1 and moving the patient to a lower position, which increases the workload of the carrying personnel.

[0049] The thigh positioning frame 4 includes a first positioning frame 41 and a second positioning frame 42. The first positioning frame 41 is rotatably mounted on the adjustment frame 3 via a first hinge frame 45. The second positioning frame 42 is slidably connected to the upper side of the first positioning frame 41 away from the adjustment frame 3. The sliding parts of the first positioning frame 41 and the second positioning frame 42 overlap up and down. A limiting block 43 is fixedly connected below the overlapping part of the second positioning frame 42. The limiting block 43 is inserted into the overlapping part of the first positioning frame 41. The limiting block 43 is horizontally slidably connected to the first positioning frame 41. A first restraint belt 46 is arranged above the first positioning frame 41.

[0050] Through the sliding structure of the first positioning frame 41 and the second positioning frame 42, the thigh positioning frame 4 can be extended and retracted, so that it can be suitable for patients of different ages and shapes. Through the structure of the limit block 43, the first positioning frame 41 and the second positioning frame 42 are prevented from falling off and sliding and offsetting. After the length of the thigh positioning frame 4 is adjusted, the patient's legs are fixed to the thigh positioning frame 4 with the first restraint belt 46.

[0051] A rack 44 is installed in the middle of the upper part of the overlapping part of the first positioning frame 41, and a positioning column 5 is arranged in the end of the overlapping part of the second positioning frame 42. The positioning column 5 is slidably connected with the second positioning frame 42, and the positioning column 5 is clamped with the tooth block of the rack 44. A third spring 51 is arranged above the positioning column 5, and the two ends of the third spring 51 are respectively fixedly connected to the positioning column 5 and the inner wall of the second positioning frame 42. A second connecting rope 53 is also arranged above the positioning column 5, and the second connecting rope 53 passes through the second positioning frame 42 and passes through the side of the second positioning frame 42. The end of the second connecting rope 53 passing through the second positioning frame 42 is fixedly connected with a pulling block 54.

[0052] Pull the pull block 54 outward so that the second connecting rope 53 drives the positioning column 5 to retract into the second positioning frame 42, allowing the two to slide relative to each other to adjust the length of the thigh positioning frame 4, and loosen the pull block 54 so that the second connecting rope 53 loses its restraining force. Under the elastic force of the third spring 51, the positioning column 5 is stuck in the gap between different tooth blocks in the rack 44, so that the thigh positioning frame 4 is fixed after being adjusted to different lengths, thereby preventing the length of the thigh positioning frame 4 from changing during rehabilitation training, causing secondary injury to the patient's knee joint.

[0053] The calf positioning frame 6 is rotatably connected to the second positioning frame 42 via a rotating wheel 61 , and the rotating wheel 61 is driven by an external motor. A second binding belt 62 is disposed above the calf positioning frame 6 .

[0054] The patient's calf is fixed to the calf positioning frame 6 by the second restraint belt 62, and the rotation of the rotating wheel 61 is controlled by the motor so that the angle between the calf positioning frame 6 and the thigh positioning frame 4 can be controlled. The angle between the calf positioning frame 6 and the thigh positioning frame 4 is adjusted according to the angle between the thigh positioning frame 4 and the adjustment frame 3.

[0055] The rotating plate 8 is arranged between the fixed seat 7 and the thigh positioning frame 4, and the rotating plate 8 is arranged below the side of the thigh positioning frame 4 close to the adjustment frame 3. The upper surface of the rotating plate 8 abuts against the bottom of the first positioning frame 41, and the rotating plate 8 can slide relative to the bottom of the thigh positioning frame 4. A driving rod 81 is arranged below the rotating plate 8, and the driving rod 81 passes through the fixed seat 7. The driving rod 81 is installed on the moving seat 1. The upper end of the driving rod 81 is rotatably connected to the rotating plate 8 through the third hinge frame 82. The driving rod 81 controls the rotating plate 8 to rise and fall, so that the rotating plate 8 rotates following the flipping of the thigh positioning plate 4.

[0056] According to the leg of the patient who needs rehabilitation training, the corresponding driving rod 81 is selected and started. If both legs of the patient need rehabilitation training, the two driving rods 81 are started at the same time;

[0057] The driving rod 81 controls the rotating plate 8 to rise and lifts up the thigh positioning plate 4. Due to the screw rods of the rotating plate 8 and the driving rod 81, they rotate in the same way. According to the patient's recovery condition, the travel distance of the driving rod 81 is controlled to control the bending amplitude of the patient's legs to avoid wound tearing.

[0058] The calf positioning frame 6 is provided with a telescopic rod 64 near the bottom of the thigh positioning frame 4, and an elastic component is provided in the telescopic rod 64. The top of the telescopic rod 64 is rotatably connected to the calf positioning frame 6 through a second hinge frame 63. The telescopic rod 64 is provided on a fixed seat 7. The telescopic rod 64 vertically penetrates the fixed seat 7 and is slidably connected to a slide groove on the fixed seat 7. The fixed seat 7 is provided below the thigh positioning frame 4, and the fixed seat 7 extends to a part of the bottom of the calf positioning frame 6. The fixed seat 7 is fixedly connected to the adjustment frame 3 through a rod.

The slide plate 9 is horizontally slidably connected to the guide rail 12, and the guide rail 12 is installed on the moving seat 1. A fourth spring 91 is arranged between the slide plate 9 and the end of the guide rail 12, and the two ends of the fourth spring 91 are respectively fixedly connected to the slide plate 9 and the guide rail 12. A third connecting rope 92 is fixedly connected to the side of the slide plate 9 facing the end of the guide rail 12, and the third connecting rope 92 passes through the end of the guide rail 12 and is fixedly connected to the connecting plate 83. The connecting plate 83 is installed between the rotating plates 8 on both sides, and the connecting plate 83 can be fixed to the rotating plate 8 on one side.

[0060] The elastic component structure of the telescopic rod 64 supports the rotation of the calf positioning frame 6, assists the rotation between the calf positioning frame 6 and the thigh positioning frame 4, and the telescopic rod 64 can move when the calf positioning frame 6 is turned over;

[0061] During the flipping process of the thigh positioning frame 4, the connecting plate 83 moves upward, so that the third connecting rope 92 drives the slide plate 9 to slide in the direction of the guide rail 12, ensuring that the position of the telescopic rod 64 can be synchronized with the rotation of the calf positioning frame 6. After the thigh positioning frame 4 is reset to the horizontal, the third connecting rope 92 is loosened, and under the elastic force of the fourth spring 91, the slide plate 9 drives the telescopic rod 64 to reset.

[0062] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
