Description

Technical Field

[0001] The utility model relates to the technical field of neurology, in particular to a limb exerciser for neurology. Background Art

[0002] Neurology is a secondary discipline about nerves. It does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases, migraine, brain inflammatory diseases, myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy and myasthenia gravis. In the nursing process of neurology, a limb exerciser for neurology nursing is needed.

[0003] For some patients who have been bedridden for a long time, lying in bed for a long time can easily lead to adverse conditions such as muscle atrophy, so caregivers are required to regularly exercise the patients' limbs, usually by helping the patients' limbs to flex and extend back and forth, to promote blood circulation and avoid muscle atrophy. However, this consumes more time and energy of caregivers, so it is necessary to design a limb exerciser to solve this problem.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 5 , the utility model provides a technical solution:

[0029] A limb exerciser for neurology comprises a support arm 1, support rods 3 are rotatably installed at both ends of the support arm 1, the outer surfaces of the two support rods 3 are movably sleeved with extension mechanisms 2 with telescopic functions, and the two support rods 3 are fixedly installed with connecting rods 6 through two groups of extension mechanisms 2, one end of the inner sides of the two connecting rods 6 are rotatably installed with a speed change mechanism 7 for adjusting the massage effect, a massage arm 5 with a pressing and activating blood circulation function is fixedly connected between the two speed change mechanisms 7, and the outer ends of the two support rods 3 are fixedly installed with a fixing mechanism 4 capable of clamping the bed legs.

[0030] By adopting the above technical solution, when using the device, first, the family member or nurse fixes the device to the bed leg through the two fixing mechanisms 4, then pulls the massage arm 5 with both hands to extend the extension mechanism 2, and the patient places the legs between the support arm 1 and the massage arm 5, and then releases the massage arm 5 so that the extension mechanism 2 rebounds and clamps the patient's legs between the massage arm 5 and the support arm 1. At this time, the patient's legs can be slowly straightened with a slight force. Due to the effect of the speed change mechanism 7, the speed change mechanism 7 starts to work when the patient exerts a slight force, increasing the rotation speed of the massage arm 5, and the patient's legs are straightened, so that the patient can feel the movement of the legs and adapt to this action, thereby improving the massage effect and achieving The massage action has different massage speeds and varying strengths. When the patient needs to put down his legs and bend them slightly, the speed change mechanism 7 will be reset downward with gravity to facilitate the next massage. When the patient straightens his legs, the extension mechanism 2 will extend as the patient straightens his legs. At the same time, since the patient's legs are stretched in an arc shape, the massage arm 5 will rotate under the action of the connecting rod 6, and the convex balls 51 on the massage arm 5 will massage the patient's legs, increase blood circulation, reduce the patient's discomfort, and make the patient's legs recover faster. The device has a simple structure, is easy to carry, and has low cost, so it is suitable for patients to take home for rehabilitation training.

[0031] Specifically, Figure 1 As shown, convex balls 51 are equidistantly arranged on the surface of the massage arm 5 , and sponge cushions 8 are fixedly sleeved on the outer surfaces of the support arm 1 and the massage arm 5 , and the sponge cushions 8 on the surface of the massage arm 5 are arranged between the convex balls 51 .

[0032] By adopting the above technical solution, during the operation of the equipment, the sponge cushion 8 can reduce the discomfort caused by the convex ball 51 to the patient's legs, and at the same time, being closer to the skin, the convex ball 51 can play a massage role, facilitate blood circulation in the patient's legs, and reduce the patient's discomfort during rehabilitation training.

[0033] Specifically, Figures 1 to 3As shown, the speed change mechanism 7 includes a disc 71, a limiting ring 72, a coil 73, a coil spring 74, an annular groove 75, a second spring 76, a top block 77, a limiting plate 78 and a touch ball 79. The two connecting rods 6 are rotatably mounted on the inner wall of the disc 71. The limiting ring 72 is fixedly mounted on the inner wall of the disc 71. The limiting ring 72 is divided into an inner ring and an outer ring on the inner and outer surfaces of the radius. The inner ring of the limiting ring 72 is provided with a coil 73, which is fixedly mounted on the inner wall of the disc 71. The outer surfaces of the two connecting rods 6 are fixedly sleeved with There is a coil spring 74 used in conjunction with the rolling plate 73, and a touch ball 79 is fixedly installed on the outermost end of the coil spring 74, and an annular groove 75 is opened on the outer ring of the limit ring 72, and a second spring 76 is fixedly installed on the inner wall of the annular groove 75. The bottom of the second spring 76 is fixedly connected to a top block 77 used in conjunction with the touch ball 79, and the top block 77 passes through the limit ring 72 and can move up and down in the penetration position. A limit plate 78 is set at the end of the limit ring 72 and the rolling plate 73, and the limit plate 78 is used to connect the limit ring 72 and the rolling plate 73.

[0034] The elastic force of the coil spring 74 is smaller than the elastic force of the second spring 76 , and the coil spring 74 is in an expanded state when in a stationary state.

[0035] When the patient straightens his legs and lifts his legs, the connecting rod 6 will first rotate counterclockwise relative to the clockwise rotation of the massage arm 5. At this time, the coil spring 74 contracts and the touch ball 79 at the top moves and contacts the top block 77. As the patient's legs exert a little force, the coil spring 74 is provided with a force to contract and rotate and move the top block 77. When the force here is greater than the elastic force of the second spring 76, the touch ball 79 will push the top block 77 open to cause the second spring 76 to contract. Subsequently, the coil spring 74 rebounds in the winding plate 73. At this time, the force during the rebound will be fed back to the connecting rod 6, so that the rotation speed of the connecting rod 6 will be accelerated. After the patient's legs are straightened, the patient's legs fall with gravity. At this time, the touch ball 79 will push the second spring 76 to contract again and contact the limit plate 78. The coil spring 74 works and stretches, slowing down the massage speed of the massage arm 5. The massage speed of the massage arm 5 is changed by the speed change mechanism 7, thereby improving the massage effect of the massage arm 5.

[0036] Specifically, Figure 1 and Figure 5 As shown, the extension mechanism 2 includes a first rectangular rod 21, a contraction groove 22, a first spring 23 and a second rectangular rod 24, the first rectangular rod 21 is fixedly connected to the connecting rod 6, and is characterized in that: the extension mechanism 2 includes an integrally connected second rectangular rod 24 rotatably sleeved on the outer surface of the support rod 3, a contraction groove 22 is opened inside the first rectangular rod 21, and the inner wall of the contraction groove 22 is fixedly connected to the first spring 23, and one end of the first spring 23 is fixedly connected to the second rectangular rod 24.

[0037] The second rectangular rod 24 can be retracted into the contraction groove 22 following the spring in a static state.

[0038] By adopting the above technical solution, when the patient places his legs between the massage arm 5 and the support arm 1, the massage arm 5 can be pulled away by a family member or a nurse. At this time, the first rectangular rod 21 will pull the second rectangular rod 24 out of the contraction groove 22 inside the first rectangular rod 21 as the massage arm 5 moves away from the support arm 1. When the second rectangular rod 24 is pulled out, the first spring 23 will extend. After the patient places his legs between the massage arm 5 and the support arm 1 and releases the massage arm 5, the first spring 23 rebounds and pulls the first rectangular rod 21 back, so that the patient's legs are clamped between the massage arm 5 and the support arm 1, which is convenient for subsequent massage.

[0039] Specifically, Figure 1 and Figure 4 As shown, the fixing mechanism 4 includes a hinged column 41 fixedly connected to the outer end of the support rod 3, and the outer surfaces of the two groups of hinged columns 41 are provided with a circle of slide grooves 42, and matching sliders 43 are symmetrically and movably arranged in the slide grooves 42, and two sliders 43 form a group, and the outer surface of each slider 43 is fixedly connected to a fixing ring 44, and each group of two fixing rings 44 is fixedly installed by screws 45.

[0040] One of the fixing rings 44 in each group of fixing rings 44 is provided with a thread matching the screw 45, and the other fixing ring 44 is not threaded. The screw 45 is divided into a threaded end and a non-threaded end, and the diameter of the threaded end is smaller than the diameter of the non-threaded end. The hole diameter of the other fixing ring 44 for inserting the screw 45 is smaller than the diameter of the threaded end of the screw 45.

[0041] By adopting the above technical solution, when the device is installed on a hospital bed or at home, the two groups of fixing rings 44 can be separated by screws 45, and the two fixing rings 44 of each group move in opposite directions. When moving, the slider 43 will rotate in the slide groove 42 on the hinge column 41, so that the two fixing rings 44 of each group are separated. At this time, the fixing ring 44 is moved to the cylindrical position of the hospital bed leg or the home, and the two fixing rings 44 in each group are aligned by rotating the slider 43 in the slide groove 42, and then the screws 45 are rotated to fix the two fixing rings 44 to the hospital bed leg or two cylindrical objects at home. The device can be fixed, which is convenient to carry, suitable for home and hospital, and low cost.

[0042] Working principle: When using the device, first, the family member or nurse fixes the device to the bed leg through two fixing mechanisms 4, then pulls the massage arm 5 with both hands to extend the extension mechanism 2, and the patient places the legs between the support arm 1 and the massage arm 5. At this time, the patient's legs can be slowly straightened with a slight force. Under the patient's slight force, the speed change mechanism 7 starts to work, increasing the rotation speed of the massage arm 5, and the patient's legs are straightened, so that the patient can feel the movement of the legs and adapt to this action, thereby improving the massage effect and achieving different massage speeds and massage actions with varying strengths. Then the patient needs to put down his legs. When the legs are slightly bent, the speed change mechanism 7 will be reset downward due to gravity, which is convenient for the next massage. When the patient's legs are straightened, the extension mechanism 2 will extend as the patient's legs are straightened. At the same time, since the patient's legs are straightened in an arc shape, the massage arm 5 will rotate under the action of the connecting rod 6, and the convex ball 51 on the massage arm 5 will massage the patient's legs, increase blood circulation, reduce the patient's discomfort, and make the patient's legs recover faster. The device has a simple structure, is easy to carry, and has low cost, so it is suitable for patients to take home for rehabilitation training.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
