Description

Technical Field

[0001] The invention relates to the technical field of cardiovascular nursing equipment, and in particular to a limb muscle atrophy prevention and training device for patients with cardiovascular diseases. Background Art

[0002] The heart is the ejection organ of blood circulation. It has the function of a pump and pushes blood circulation. Its main function is to supply oxygen to the body and remove metabolic products from the body. As the life of modern society has improved, people do not pay attention to their physical health. They drink too much, smoke too much, are nervous, tired, excited, and eat too much. In these cases, some heart diseases often occur. The diseases caused are called cardiovascular diseases, also known as circulatory system diseases. Heart diseases include arrhythmia, heart failure, coronary atherosclerosis and other diseases. Different diseases have different symptoms and manifestations, and different diseases should have different prevention and care. However, each type of care tries to avoid patient exercise, especially exercise that causes sweating and accelerates blood flow, and requires patients to rest. However, lack of exercise may lead to the following problems: (1) Long-term inactivity can cause muscle aches throughout the body, stiff neck, headaches and dizziness; (2) it can easily cause slower gastrointestinal motility, reduced secretion of digestive juices by the digestive glands, loss of appetite and other symptoms, and worsen digestive system symptoms such as abdominal distension, constipation and indigestion; (3) it can cause psychological depression, irritability and poor mental state; (4) Long-term inactivity can cause muscle atrophy.

[0003] The Chinese patent with the publication number CN106139532B discloses a device for preventing limb muscle atrophy of patients with cardiovascular diseases. The device is designed to prevent limb muscle atrophy of patients with cardiovascular diseases by designing an upper limb exercise mechanism composed of a bracket, a cantilever, a cable, a handle and a tension adjustment mechanism, and a lower limb exercise mechanism composed of a bracket, a pedal track mechanism, a cable, a pedal and a tension adjustment mechanism. The device can make the upper and lower limbs move easily according to the physical condition of the patient with cardiovascular disease. Because there are gripping points and pedaling points, it can save more effort than swinging the upper limbs and swinging the lower limbs in the air; it provides an appropriate sense of force, so that the nervous system and muscles of the upper and lower limbs can be coordinated and exercised during exercise. The beneficial effects of this scheme can be known from the description of the above scheme. It has a simple structure and a reasonable design. It can not only allow cardiovascular patients to perform necessary exercise exercises for the skeletal muscles of the limbs and the nervous system, but also because of the ingenious design, the patient will not cause the blood to flow faster due to exercise.

[0004] However, the limb muscle atrophy prevention training device for patients with cardiovascular diseases mentioned above is not sufficient to meet the patients' comprehensive limb muscle training needs, resulting in limited training effects. In addition, the training method is relatively single and cannot mobilize the patients' enthusiasm for training. The comfort is relatively poor. At the same time, it cannot be adjusted according to the patients' own needs, and its applicability is relatively low. Summary of the invention

[0026] As an optimization technical solution of the present invention, during the patient's upper limb exercise, the patient pulls the stretching rod 32 with both hands, uses the first pulley rope 33 to drive the counterweight mechanism 6 to achieve the patient's upper limb exercise, and uses the first guide pulley 31 to change the direction of the force, which can also ensure the smoothness of the stretching rod 32 during the stretching process and improve the exercise effect.

[0027] In the above scheme, the arm flexion and extension mechanism 5 includes an arc-shaped arm 51, a push-pull rod 52 and a deflection plate 53. Extension plates 22 are respectively arranged on the left and right sides of the upper end of the support plate 2. The deflection plate 53 is rotatably connected to the lower side of the free end of the extension plate 22. The arc-shaped arm 51 is connected to the deflection plate 53, the push-pull rod 52 is connected to the free end of the arc-shaped arm 51, and a second guide pulley 23 is arranged at the lower middle part of the extension plate 22.

[0028] As an optimized technical solution of the present invention, the patient can grasp the push-pull rod 52 with both hands, and use the effective opening and closing of the arms to drive the arc arm 51 to rotate back and forth, thereby causing the arc arm 51 to deflect around the deflection disk 53, and use the counterweight mechanism 6 to provide resistance for the exercise process to ensure the exercise effect of the patient's upper limb in another exercise mode. At the same time, the second pulley rope 54 can change the connection position with the deflection disk 53, thereby changing the exercise intensity of the arm flexion and extension mechanism 5.

[0029] In the above scheme, the transmission mechanism includes a turntable 24, a third guide pulley 25, a universal coupling 26 and a transmission shaft 27. A transmission groove 21 extending up and down is penetrated through the middle of the support plate 2. The third guide pulley 25 is arranged on the upper side of the transmission groove 21.

The free end of the third pulley rope 9 passes around the third guide pulley 25 and is connected to the pedal mechanism 7.

[0030] As an optimization technical solution of the present invention, the third pulley rope 9 can drive the turntable 24 to rotate through its connection relationship with the edge of the turntable 24 during exercise, and then the turntable 24 can drive the universal coupling 26 to rotate. The reversing and transmission effects of the universal coupling 26 can drive the transmission shaft 27 to rotate, and then the transmission shaft 27 can be used to drive the counterweight mechanism 6, so that the resistance of the counterweight mechanism 6 can form resistance during the patient's exercise.

[0031] In the above scheme, the backrest 4 includes a mounting tube 41, a seat plate 42 and a backrest 43. The seat plate 42 is connected to the top of the mounting tube 41 in a liftable manner. The backrest 43 is connected to the rear side of the mounting tube 41. An arc-shaped lumbar plate 431 is arranged in the middle of the backrest 43.

A mounting groove 44 opening backwards is arranged at the bottom of the mounting tube 41, and the pedaling mechanism 7 is arranged in the mounting groove 44.

[0032] As an optimized technical solution of the present invention, a hydraulic cylinder 45 is arranged on the inner side of the top of the mounting tube 41, and the output end of the hydraulic cylinder 45 is connected to the bottom of the seat plate 42, so that the seat plate 42 can be driven to move up and down by the hydraulic cylinder 45, so as to adjust the height of the seat plate 42 according to the patient's own situation, improve the applicability of the device, and ensure that it is suitable for the exercise needs of different patients. At the same time, an arc-shaped lumbar plate 431 and an arc-shaped cervical plate 432 are arranged on the backrest 43. The arc-shaped lumbar plate 431 and the arc-shaped cervical plate 432 are made of elastic soft material, and can also be a sponge pad, which can not only protect the patient's waist, but also ensure the patient's comfort during exercise.

[0033] In the above scheme, the pedal mechanism 7 includes a first pedal 71, a second pedal 72, a transmission sleeve 73, a rotating sleeve 74 and a rotating shaft 75. The transmission sleeve 73 passes through the inner walls on the left and right sides of the installation groove 44. The rotating shaft 75 is arranged in the transmission sleeve 73. The first pedal 71 is connected to the two ends of the rotating shaft 75 in opposite directions through the first connecting rod 711. The second pedal 72 is connected to the two ends of the transmission sleeve 73 in the same direction through the second connecting rod 721. The rotating sleeve 74 is fixedly connected to the middle part of the transmission sleeve 73. An inner half tooth 741 is arranged on the inner side of the rotating sleeve 74. An outer half tooth 751 is arranged in the middle part of the rotating shaft 75. The outer half tooth 751 is intermittently meshed with the inner half tooth 741.

[0034] As an optimized technical solution of the present invention, the second pedal 72 is connected to the two ends of the transmission sleeve 73 in the same direction through the second connecting rod 721, so that the patient can drive the transmission sleeve 73 to deflect by synchronously lifting or pressing down both feet, and then the rotating sleeve 74 is used to drive the transmission mechanism to rotate through the third pulley rope 9, and finally transmit it to the counterweight mechanism 6 to complete the exercise action. The rotating sleeve 74 is also provided with a torsion spring, which can ensure that the transmission sleeve 73 returns to the initial position. The first pedal 71 is connected to the two ends of the rotating shaft 75 in the opposite direction through the first connecting rod 711 to form a structure similar to a bicycle pedal, so that the patient can rotate by stepping on the first pedal 71. During the rotation of the rotating shaft 75, the inner half gear 741 can be intermittently driven to rotate through the outer half gear 751, and the reciprocating flipping of the transmission sleeve 73 can be realized by cooperating with the counterweight mechanism 6, so as to achieve the exercise effect of the patient's lower limbs in two different exercise modes. In the above scheme, a reversing shaft 8 is arranged at the lower front side of the pedal mechanism 7, a reversing wheel 81 is arranged in the middle of the reversing shaft 8, a third pulley rope 9 is bound to the rotating sleeve 74, and the third pulley rope 9 passes around the reversing wheel 8 and is connected to the transmission mechanism.

[0035] As an optimization technical solution of the present invention, the reversing wheel 81 on the reversing shaft 8 can realize the reversing and guiding function of the third pulley rope 9, thereby ensuring the smoothness during the exercise.

[0036] In the above scheme, the counterweight mechanism 6 includes a first counterweight block 61, a second counterweight block 62, a guide slide rod 63 and a spring damper 64. A movable groove 28 communicating with the transmission groove 21 is provided on the lower side of the support plate 2. The guide slide rod 63 is provided on the left and right sides of the bottom of the movable groove 28. The first counterweight block 61 and the second counterweight block 62 are slidably connected to the guide slide rods 63 on both sides at both ends. The first counterweight block 61 is located above the second counterweight block 62. The spring damper 64 is provided between the first counterweight block 61 and the second counterweight block 62 and at the bottom of the second counterweight block 62. A screw 271 is provided at the lower end of the transmission shaft 27. The screw 271 is located between the guide slide rods 63. The first counterweight block 61 is threadedly connected to the screw 271, and the second counterweight block 62 is sleeved on the screw 271 through the through hole 621.

[0037] As an optimization technical solution of the present invention, during the patient's upper limb exercise, the patient can choose different exercise modes and use the first pulley rope 33 or the second pulley rope 54 to drive the second counterweight block 62 to slide upward along the guide rod 63. The spring dampers 64 respectively arranged on the upper and lower sides of the second counterweight block 62 can generate resistance during the patient's exercise, and the spring dampers 64 can be used to restore the stretching mechanism and the arm flexion and extension mechanism 5 to their initial states.

[0038] During the patient's exercise, the patient can also choose different exercise modes. By stepping on the second pedal 72, the lower end of the third pulley rope 9 can be driven to be wound through the rotating sleeve 74 on the transmission sleeve 73, and then pass through the reversing wheel 81 on the reversing shaft 8, and then be transmitted to the side of the turntable 24 through the third guide pulley 25, and then the turntable 24 can be driven to rotate. The turntable 24 will drive the transmission shaft 72 to rotate through the universal joint 26, and then the screw 271 at the lower end of the transmission shaft 27 can be rotated. Through the threaded connection relationship between the screw 271 and the first counterweight block 61, the first counterweight block 61 can be driven to move up and down along the guide slide rod 63, thereby realizing the exercise of the patient's lower limbs.

[0039] Furthermore, the patient can also step on the first pedal 71 to drive the rotating shaft 75 to rotate. By utilizing the intermittent meshing relationship between the outer half teeth 751 and the inner half teeth 741 in the middle of the rotating shaft 75, the rotating sleeve 74 can be driven to rotate intermittently, and then the transmission sleeve 73 can be driven to rotate. The turntable 24 can be driven to rotate through the third pulley rope 9, and the transmission shaft 27 can be driven to rotate by the universal coupling 26. Then, the screw 271 can be used to drive the first counterweight block 61 to move up and down along the guide rod 63, thereby completing the patient's lower limb exercise work in another exercise mode.

[0040] In the above solution, the movable slot 28 is provided with second through slots 281 extending up and down on the left and right sides respectively, and a slide bar 622 is movably connected in the second through slot 281 , and the slide bar 622 is connected to the second counterweight block 62 .

[0041] As an optimized technical solution of the present invention, second through grooves 281 are provided on both sides of the movable groove 28 to facilitate the sliding of the slide rod 622 , and the slide rod 622 can drive the second counterweight block 62 to smoothly rise and fall in the movable groove 28 .

[0042] Specific implementation cases: When cardiovascular disease patients need to exercise their limb muscles, they can adjust the height of the backrest 4 according to their own conditions, and use the hydraulic cylinder 45 to drive the seat plate 42 to move up and down, so as to adjust the seat plate 42 to a reasonable height.

[0043] When it is necessary to exercise the upper limbs, the patient can hold the stretching rod 32 with both hands, and use the stretching rod 32 to drive the second counterweight 62 to slide upward along the guide rod 63 through the first pulley rope 33. The spring damper 64 can provide effective resistance for the patient's pulling. When the pulling of both hands is released, the second counterweight 62 can return to the initial position under the recovery action of the spring damper 64. This cycle is repeated to complete the patient's upper limb exercise.

[0044] Furthermore, the patient can grasp the push-pull rod 52 with both hands, and use the expansion and contraction of the patient's hands to drive the arc arm 51 to flip back and forth, and then use the second pulley rope 54 connected to the deflection plate 53 to drive the second counterweight block 62 to slide upward along the guide rod 63, and cooperate with the spring damper 64 to provide effective resistance during the contraction of the patient's arms. When the arms are expanded, the second counterweight block 62 can return to the initial position under the restoring action of the spring damper 64, and this cycle can be repeated to complete the exercise movements of the patient's upper limbs in another exercise mode.

[0045] When the patient's lower limbs need to be exercised, the patient can step on the second pedal 72 with both feet. By lifting or pressing down with both feet, the transmission sleeve 73 can be driven to rotate, and then the rotating sleeve 74 can be driven to realize the winding of the third pulley rope 9, and then the turntable 24 can be driven to rotate through the reversing wheel 81 and the third guide pulley 25, and then the transmission shaft 27 can be driven to rotate through the universal coupling 26. The transmission shaft 27 can drive the first counterweight block 61 to slide upward along the guide rod 63 through the threaded connection relationship between the screw 271 at its lower end and the first counterweight block 61, and then cooperate with the traction of the spring damper 64, as well as the weight of the first counterweight block 61 and the second counterweight block 62 to hinder the exercise of the patient's lower limbs, so as to facilitate the patient to exercise the lower limbs.

[0046] The rotation of the first pedal 71 drives the rotating shaft 75 to rotate, and then the outer half-tooth 751 and the inner half-tooth 741 are matched. Every time the rotating shaft 75 rotates one circle, the outer half-tooth 751 drives the inner half-tooth 741 to rotate half a circle, so that the third pulley rope 9 is wound around the rotating sleeve 74, and then the third pulley rope 9 drives the rotating disk 24 to deflect, and the transmission shaft 27 is driven to rotate through the universal coupling 26, and then the first counterweight block 61 is driven to move up. After the transmission sleeve 73 rotates half a circle, it will move down along the guide slide rod 63 under the pull of the spring damper 64, and then the transmission shaft 27 is used to rotate in the opposite direction by utilizing the matching relationship between the screw rod 271 and the first counterweight block 61, and then the transmission sleeve 73 can be returned to the initial position under the action of the torsion spring on the rotating sleeve 74, so that the patient can complete another exercise mode of the patient's lower limbs by continuously stepping on the first pedal 71.

[0047] Finally, patients can choose different exercise modes. Combining different exercise modes can exercise the patient's limbs in an all-round way, improve the patient's own exercise effect, and increase the patient's enthusiasm for exercise through a variety of exercise modes.
