Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and specifically to a rehabilitation exercise walker. Background Art

[0002] Tumors and related treatments may all cause cancer-related fatigue (CRF) in patients, which is mainly manifested as non-specific weakness, fatigue, general decline, and increased drowsiness. The symptoms can last for more than 2 weeks. In addition, surgical oncology patients have large surgical scopes, large surgical incisions, many drainage tubes, and low protein levels, etc., all of which will cause postoperative fatigue and weakness in patients. Weak and postoperative patients all need to use walkers - the usage of walkers is large.

[0003] As the patient recovers, the role played by the walker gradually decreases. And in order to accelerate the recovery speed, it is necessary to alternately use the effects of two rehabilitation exercises. One is the pedaling bicycle type with legs crossing in a cycling mode, and the other is the circular motion of both legs synchronously, which helps the patient recover the hamstring muscles, quadriceps femoris, and lumbar spine, etc. However, when the two rehabilitation methods are integrated, it is very troublesome to switch. And when the two legs perform circular motion synchronously, due to the difficulty of exerting force, it is difficult to complete a set of rehabilitation exercises with the same exercise resistance as when cycling. Therefore, a device that can automatically judge the patient's movement mode and adaptively switch its corresponding exercise resistance is needed to solve the above problems.

Detailed Description of the Invention

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-7, Embodiment 1 provided by the present invention: A rehabilitation exercise walking aid, comprising two first frames 1. At the ends of both of the two first frames 1, first support columns 11 are fixedly provided. A semi-automatic gripper 22 is sleeved on the first support columns 11. On the inner side walls of both of the two first frames 1, telescopic handles 9 are fixedly provided. At the bottoms of the two first support columns 11, mounting plates 12 are fixedly provided. At the bottoms of both of the two mounting plates 12, universal wheels 13 are provided. At the ends of both of the two first support columns 11, two second frames 10 are fixedly provided. The two first frames 1 are fixedly connected to each other. At the bottoms of the two first frames 1, second support columns 19 are provided. At the bottoms of the two second support columns 19, fixing blocks 18 are fixedly provided. On the side wall of the fixing block 18, a telescopic rod 3 is fixedly provided. A seat cushion 2 is inserted and arranged on the side wall of the telescopic rod 3. A resistance adjustment mechanism 4 is slidably arranged inside the telescopic rod 3. Two locking mechanisms 5 are arranged inside the fixing block 18. At the bottom of the fixing block 18, two side plates 17 are fixedly provided. Between the two switching mechanisms 6, a wheel 16 is rotatably arranged. At the center of the wheel 16, a central column is provided. At both ends of the central column, switching mechanisms 6 are provided. At the ends of the two switching mechanisms 6 facing away from the wheel 16, rotating shafts 151 are fixedly provided. On both of the two rotating shafts 151, connecting rods 15 are fixedly sleeved. At the ends of both of the two connecting rods 15 facing away from the rotating shafts 151, pedals 14 are rotatably arranged. At the top of the second frame 10, an infusion stand 20 is fixedly provided. At the bottoms of the four second frames 10 and the two first frames 1, a number of hooks 21 are fixedly provided. First, pull the telescopic rod 3 to adjust the seat cushion 2 to a suitable position. The patient sits on the seat cushion 2. Then, the semi-automatic gripper 2 is controlled to clamp and limit the patient's waist. It should be noted that: the semi-automatic gripper 2 is a prior art and will not be elaborated here. Then, the training resistance of the resistance adjustment mechanism 4 is adjusted according to the patient's physical rehabilitation condition. Then, the locking mechanism 5 locks the wheel 16. Then, the patient's infusion tube is hung on the hook 21, and the infusion bottle is hung on the infusion stand 20. The length of the telescopic rod 3 is adjusted to a suitable length. Then, the seat cushion 2 is flipped open. The patient sits on the seat cushion 2 and steps on the foot pedals 14 with both feet. According to the training and rehabilitation plan, when the patient is performing cycling training, the switching mechanism 6 remains unchanged. When the patient is performing rehabilitation training of circular motion rowing with both legs, the switching mechanism 6 automatically detects and adaptively reduces a certain amount of training resistance without manual operation, and automatically identifies and adjusts the training resistance.

[0027] Specifically, each of the two resistance adjusting mechanisms 4 includes a U-shaped abutting rod 41, three wedge-shaped long rods 42, three abutting springs 43 and three abutting plates 44. The three abutting long rods are slidably and limitedly arranged on the side wall of the fixed block 18. The three abutting plates 44 are fixedly arranged on the side walls of the three abutting long rods. The three abutting springs 43 are respectively fixedly arranged at the bottoms of the three abutting plates 44. Three card slots are arranged inside the telescopic rod 3. The U-shaped abutting rods 41 are respectively clamped inside the three card slots. The end parts of the U-shaped abutting rods 41 are respectively in abutting cooperation with the three wedge-shaped long rods 42. By lifting the U-shaped abutting rod 41 and then pushing the U-shaped abutting rod 41 towards the fixed block 18, the U-shaped abutting rod 41 is stuck inside the corresponding card slot. And as the U-shaped abutting rod 41 moves towards the fixed block 18, the corresponding wedge-shaped long rod 42 is synchronously abutted and moved downward. The more the corresponding wedge-shaped long rod 42 moves downward, the greater the corresponding abutting force, so that the training resistance is greater. Thus, the training resistance is adjusted according to the patient's rehabilitation condition, ensuring that patients in different rehabilitation stages have a certain training effect and shortening the rehabilitation period.

[0028] Specifically, each of the two locking mechanisms 5 includes a locking rod 51, a sleeve rod 52, a wedge-shaped block 53, a wedge-shaped groove 54, an anti-disengagement plate 55, a tapered block 56 and a limiting component. The locking rod 51 is inserted and arranged inside the fixed block 18 and the side plate 17. The wedge-shaped groove 54 is arranged on the locking rod 51. The wedge-shaped block 53 is inserted and arranged inside the side plate 17. The anti-disengagement plate 55 is fixedly arranged at the bottom of the wedge-shaped block 53. The limiting component is arranged on the central column. The sleeve rod 52 is sleeved on the limiting component. The tapered block 56 is fixedly arranged on the sleeve rod 52. By pressing down the locking rod 51, the wedge-shaped groove 54 is driven to move synchronously. The wedge-shaped groove 54 abuts the wedge-shaped block 53 and moves towards the wheel 16 to abut and lock the side wall of the wheel 16. And as the locking rod 51 moves downward, it synchronously abuts the tapered block 56, causing the tapered block 56 and the sleeve rod 52 to move towards the connecting rod 15. During training, the wheel 16 can be locked to ensure the safety of the patient.

[0029] Specifically, each of the limiting components includes a tension spring 57, two limiting blocks 58 and a limiting column 59. The limiting column 59 is fixedly arranged at the end of the central column. The two ends of the tension spring 57 are respectively fixedly arranged on the limiting column 59 and the sleeve rod 52. The two limiting blocks 58 are fixedly arranged on the limiting column 59. The two limiting blocks 58 are in limiting sliding cooperation with the sleeve rod 52. By moving the sleeve rod 52, the limiting block 58 on the limiting column 59 is disengaged from the limit of the sleeve rod 52. Thus, when the wheel 16 is locked, the sleeve rod 52 can still rotate. It realizes that when the wheel 16 is locked, the device is in a static state and the patient can perform rehabilitation exercises in place, ensuring the safety of the patient during rehabilitation exercises.

[0030] Specifically, the switching mechanism 6 includes two conical wheels 61, two connecting rings 62, two electric push rods 64, two limiting bars 65, two first wedge-shaped rods 66, four L-shaped rods 68, two hemispheres 69, a two-handed operation button 610, and several second wedge-shaped rods 611. The two electric push rods 64 are fixedly arranged inside the sleeve rod 52. The two conical wheels 61 are fixedly arranged at the ends of the output shafts of the electric push rods 64. The two conical wheels 61 are rotatably connected to the corresponding rotating shafts 151. The two limiting bars 65 are symmetrically and fixedly arranged on the two sleeve rods 52 respectively. Two annular grooves are arranged inside the central column. The four L-shaped rods 68 are respectively rotatably arranged at one end of two of them inside the two annular grooves. The two connecting rings 62 are respectively fixedly arranged at the other ends of the four L-shaped rods 68. The two first wedge-shaped rods 66 are respectively fixedly arranged on the inner side walls of the two connecting rings 62, and the two wedge-shaped rods are slidably inserted and matched with the corresponding limiting bars 65. The two hemispheres 69 are respectively arranged with spherical heads inside the central column. The two-handed operation button 610 is fixedly arranged between the two hemispheres 69. The several second wedge-shaped rods 611 are respectively symmetrically arranged in a circular array inside the central column. By the patient pedaling the pedal 14 to drive the connecting rod 15 to rotate, the rotation of the connecting rod 15 drives the rotating shaft 151 to rotate and the conical wheel 61 to rotate synchronously. The rotation of the conical wheel 61 drives the electric push rod 64 and the sleeve rod 52 to rotate synchronously. The rotation of the sleeve rod 52 drives the first wedge-shaped rod 66 to rotate synchronously. When the positions of the two pedals 14 are symmetrical about the wheel 16, the two first wedge-shaped rods 66 at the same position synchronously abut against the same position on the front and back sides of the two-handed operation button 610, so that the two-handed operation button 610 is activated, driving the output shaft of the electric push rod 64 to retract, thereby driving the conical wheel 61 to move synchronously. The movement of the conical wheel 61 reduces the frictional contact area between the wedge-shaped long rod 42 and the conical wheel 61, thereby reducing the corresponding training resistance. However, when the patient performs cycling training, since the positions of the two pedals 14 are mutually misaligned with respect to the cross-section of the wheel 16, when the first wedge-shaped rod 66 abuts against the second wedge-shaped rod 611 and moves, due to the ball-head connection setting of the two-handed operation button 610, the two-handed operation button 610 tilts around the ball head, and the two switches of the two-handed operation button 610 cannot be triggered simultaneously, so that the device will not reduce the resistance during cycling training; it realizes automatic identification of the corresponding training method, and can adaptively switch the corresponding resistance according to the identified training method, without manual adjustment, with a high degree of automation, without the need for medical staff or family members to watch, and the patient does not need to get off the vehicle to adjust again, with simple operation, convenient and fast.

[0031] Specifically, the two first wedge-shaped rods 66 are in abutting cooperation with the corresponding second wedge-shaped rods 611.

[0032] Specifically, the two-handed operation button 610 is electrically connected to the two electric push rods 64.

[0033] Specifically, a display screen 8 is fixedly arranged on the tops of the two first frames 1. A connecting line is arranged on the tops of the first frames 1. A bracelet 7 is fixedly arranged at the end of the connecting line. The bracelet 7 is in telecommunication connection with the display screen 8. By the patient wearing the bracelet 7 on the wrist, the bracelet 7 monitors the heart rate and transmits the data to the display screen 8. When the set heart rate is exceeded, the bracelet 7 automatically gives an alarm to remind the patient to stop training and inform the medical staff.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
