Description

Technical Field

[0001] The present invention relates to the technical field of lower limb rehabilitation, and more specifically, to a lower limb rehabilitation device for stroke patients. Background Art

[0002] Stroke, commonly known as a stroke, is a disease in which brain cells die due to an abnormal blood flow to the brain. There are two types of cerebral vascular damage: an ischemic stroke caused by a blocked blood vessel, and a ruptured or bleeding blood vessel (such as a ruptured or leaking blood from a blood vessel in the brain). Both conditions deprive the brain of adequate blood and oxygen. In either case, brain cell damage begins within minutes, potentially leading to paralysis, difficulty speaking, and even coma.

Before using the test assembly, check the position of the fixed rod, pass the second connecting rod through the fixed rod, keep the spring in the longest state, and then let the patient bend the calf downward to 90 degrees, adjust the spring compression according to the patient's force state when bending, and after completing the debugging, let the patient continue to test and repeat the debugging process.

When the patient's calf needs to be supported, the rotating shaft where the first arc frame or the second arc frame is located is folded downward so that the inner side of the first arc frame or the second arc frame is not flush with the inner side of the rotating plate. The slider connected to the outer side of the connecting sleeve by the pull rope slides down along one end of the rotation until the magnetic plate provided on one side of the slider contacts the electromagnet. At this time, the electromagnet is energized and the electromagnet will attract the magnetic plate. After the card plate provided at the free end of the fixed-distance rope is clamped to the other magnetic plate, training can begin. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 2As shown, the spans of the runner and the second connecting rod 17 along the axis of the fixing rod 12 are equal, and the length of the fixing rod 12 is equal to the axial span of the runner plus the length of the through hole 16.

[0031] like Figure 1 and Figure 2 As shown, a control component is provided at the bottom end of the fixed rod 12, and the control component includes a connecting button 11 provided at the bottom end of the fixed rod 12, the connecting button 11 is slidably clamped at the bottom end of the base plate 5, a ring 15 is sleeved on the outside of the connecting button 11, and a control board 13 is connected to the outside of the ring 15, the control board 13 is rotatably clamped at the bottom end of the base plate 5, and the control board 13 is retractable.

[0032] like Figure 1 and Figure 2 As shown, support plates 14 are connected to both sides of the bottom surface of the base plate 5. The longitudinal span of the support plates 14 is not less than the distance between the bottom surface of the control plate 13 and the bottom surface of the base plate 5. A plurality of ventilation grooves 10 are evenly opened at one end of the base plate 5 close to the rotating plate 6.

[0033] like Figure 1 and Figure 3 As shown, a lifting assembly is provided at the bottom end of the rotating plate 6, and the lifting assembly includes a rotating shaft 18 connected to the rotating plate 6 by a torsion spring on both sides, and a plurality of first arc frames 25 and second arc frames 27 are connected to the outer sides of the two rotating shafts 18 respectively.

[0036] The lifting assembly provided in the present invention can cooperate with the conversion assembly to support the lower side of the patient's calf in batches, so as to prevent the patient from sweating during calf exercise and being unable to ventilate quickly, causing discomfort to the patient. When the patient needs to support the calf, the rotating shaft 18 where the first arc frame 25 or the second arc frame 27 is located is folded downward, so that the inner side of the first arc frame 25 or the second arc frame 27 is not flush with the inner side of the rotating plate 6. Then, at this time, the control button 19 eccentrically connected to the end plate 21 at one end of the rotating shaft 18 will loosen the connecting sleeve 20, so that the slider 23 connected to the outside of the connecting sleeve 20 by the pull rope 22 slides down along one end of the rotation until the magnetic plate 24 provided on one side of the slider 23 and the electromagnet 28 contacts, at this time the electromagnet 28 is energized, the electromagnet 28 will attract the magnetic plate 24, and after the card plate 30 set at the free end of the spacing rope 29 is clamped on the other magnetic plate 24, the training can begin.

[0038] The specific usage and function of this embodiment are as follows:

[0039] The test assembly provided in the present invention can be used in conjunction with the load assembly to help the user adjust the training load before using the device, thereby increasing the matching degree between the load weight and the patient's actual muscle strength state before training, thereby improving the training effect. Before using the test assembly, check the position of the fixed rod 12, make the second connecting rod 17 pass through the fixed rod 12, keep the spring 36 in the longest state, and then let the patient bend the calf downward to 90 degrees, and adjust the compression degree of the spring 36 according to the force state of the patient when bending. When it is necessary to increase the training force, rotate the free end of the first connecting rod 8 and rotate the rotating cylinder 34 through the fixing button 35. The screw 38 screwed on the inner side of the rotating cylinder 34 will slide along the side groove provided on its outer side, and at the same time compress the spring 36 provided between one end of the screw 38 and the second connecting rod 17, increasing the initial compression degree of the spring 36. After the adjustment is completed, let the patient continue to test and repeat the above process. After the test is completed, the contraction degree of the spring 36 is recorded and the corresponding weight block is selected to prepare for lower limb training;

[0040] After completing the selection, toggle the control plate 13 in the control assembly to make the control plate 13 rotate along the bottom end of the base plate 5 while driving the ring 15 set at its free end to move. When the control plate 13 is extended and retracted, it will drive the connecting button 11 and the fixing rod 12 mounted through the ring 15 to move horizontally along the through hole 16 until the fixing rod 12 is out of contact with the first connecting rod 8. At this time, the wheel is mounted on the protruding end of the fixing rod 12, and the load-bearing belt 9 is released through the reel on the swing rod 7. The load-bearing belt 9 is placed on the wheel mounted on one end of the fixing rod 12, and the selected counterweight block is placed on the support plate set at the free end of the load-bearing belt 9. At this time, the training intensity of the device is debugged. After fixing the patient's calf to the rotating plate 6 through the strap 2 connected to the top of the rotating plate 6, the fixing strip 3 is fixedly clamped into the fixing groove 31 opened on one side of the rotating plate 6, and training can begin.

[0041] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
