Description

Technical Field

[0002] The auxiliary limb exercise device for critical care monitoring is mainly used to enable patients to exercise when they are seriously ill. Because critically ill patients lie in bed for a long time, it is easy to cause muscle weakness and limb movement disorders. If the patient cannot move the joints in time during the optimal activity period, it will lead to joint stiffness, muscle atrophy and other adverse consequences, which will seriously affect the patient's ability to move after recovery. Therefore, a limb exercise device is needed to enable patients to perform certain exercises so that their limbs can return to normal faster.

[0003] However, most existing rehabilitation equipment only performs simple exercises, and the exercise method is to fix the patient's limbs to the equipment in a relatively rigid manner. The fixing devices on the equipment are difficult to match the limb shapes of different patients with different fixing methods, which may cause the patient's limbs to be fixed too tightly or too loosely in some positions, resulting in discomfort during use.

A second push rod 251 is formed at the bottom of the second transmission frame 25, and the second push rod 251 is integrally formed with the second transmission frame 25. Two third transmission members 27 are provided, one of which is connected to the first push rod 241 and the other is connected to the second push rod 251.

There are two embodiments: the first embodiment is that the first pull member 41 and the second pull member 42 are fixed together and form a natural whole. The second embodiment is that the first pull member 41 and the second pull member 42 are tied together by a tying buckle. In this embodiment, the first pull member 41 and the second pull member 42 are preferably tied together by a tying buckle.

[0052] In some embodiments, massage members 53 are provided on both the first supporting plate 21 and the second supporting plate 22 . The massage members 53 adopt existing technology and are fascia gun structures.

[0053] In some embodiments, a massage member 53 is provided on the third supporting plate 23 , and the massage member 53 adopts existing technology and is a fascia gun structure.

[0054] Working process: When in use, the limb needs to be placed between the first pull member 41, the second pull member 42, the first wrapping device 2 and the second wrapping device 3. There are two ways to put the limb in. The first is to use the driving device to make the first pull member 41 and the second pull member 42 in a very relaxed state. At this time, the area enclosed by the first pull member 41, the second pull member 42, the first wrapping device 2 and the second wrapping device 3 is very large, and the limb can be inserted deeper. The second method is to first separate the first pull member 41 and the second pull member 42, then place the limb on the first wrapping device 2 and the second wrapping device 3, and finally connect the first pull member 41 and the second pull member 42 together.

[0055] In this embodiment, the limbs are taken as an example of legs, which are divided into thighs and calves. The calf is placed on one support device 1, and the thigh is placed on another support device 1. Since the thigh and calf have different thicknesses, placing them on two support devices 1 can better wrap the first pull member 41 and the second pull member 42 around the thigh and calf. Since the thigh and calf are both non-cylindrical, when fixing the thigh and calf, it is necessary to adapt to the thickness of the thigh and calf at different locations to achieve self-adaptive fixation, thereby improving the patient's user experience. This is achieved by setting up a drive device.

[0056] When the limb is located between the first pulling member 41, the second pulling member 42, the first wrapping device 2 and the second wrapping device 3, refer to the rotating member 8-9 in the attached drawings and the first wrapping device 2 of the supporting device 1 in the attached drawings, and take the first wrapping device 2 of the supporting device 1 in the attached drawings as the priority reference; the pushing member 47 pushes the first movable plate 461 to move, and the first movable plate 461 drives the first transmission wheel 462 to move, and the first transmission wheel 462 drives the first transmission rope 45 to move. Specifically, the first transmission wheel 462 drives multiple points on the first transmission rope 45 to move, so that the first transmission rope 45 will form multiple tension ends 451, and the multiple tension ends 451 are subjected to force at the same time, so that the multiple tension ends 451 pull the rotating wheel 44 at the same time, and the rotating wheel 44 pulls the first pulling member 41 through the first transmission member 43. Then when one of the first pulling members 41 is in contact with the limb and the other first pulling member 41 has not yet been in contact with the limb, one of the first pulling members 41 will be unable to continue moving, and thus one of the rotating wheels 44 will be unable to continue moving. At this time, the first movable plate 461 will continue to move, but it will no longer be moving by pulling the multiple rotating wheels 44 through multiple tension ends 451. Since the rotating wheel 44 and the first transmission wheel 462 are both rotatable, the first transmission rope 45 can be moved by rotating the rotating wheel 44 and the first transmission wheel 462. This can ensure that the tension of multiple tension ends 451 is the same, that is, the tension of multiple rotating wheels 44 and the first transmission member 43 is the same, and it can also be achieved that after the first pulling member 41 is in contact with the limb, the other first pulling members 41 can continue to be tightened.

[0057] Specifically, it can be understood that the first movable plate 461 and the first transmission wheel 462 are stationary, and then one end of the first transmission rope 45 is pulled, so that the first transmission rope 45 will be subjected to force, gradually causing the rotating wheel 44 to move. However, there is a disadvantage in this, that is, the first transmission rope 45 has to go through multiple stages of transmission before it can transmit force with multiple rotating wheels 44. Then the first rotating wheel 44 that establishes a force transmission relationship with the first transmission rope 45 and the last rotating wheel 44 that establishes a force transmission relationship with the first transmission rope 45 are subjected to different tensions, so it is difficult to ensure that multiple first transmission members 43 are subjected to the same tension, that is, it is difficult to ensure that multiple first pulling members 41 are subjected to the same tension. Therefore, through the movement of the first movable plate 461 and the first transmission wheel 462, multiple force transmission relationships with the rotating wheel 44 can be formed on the first transmission rope 45, so that it can better ensure that each first transmission rope 45 is subjected to the same force, and multiple rotating wheels 44 can be moved to different positions to stop, and multiple rotating wheels 44 are subjected to the same tension at different positions, thereby ensuring that multiple first pulling members 41 fit with the thigh and calf along the length direction of the thigh and calf, and the tension wrapped around the thigh and calf is the same.

[0058] When the tension of the first pull member 41 is too large, the first drive motor 48 can be used to wind or release the first transmission rope 45 to change the length of the first transmission rope 45. The tension of the first pull member 41 can be adjusted during use, thereby further increasing the adaptability.

[0059] The movement process of the driving device at the second pulling member 42 is the same as the movement process of the driving device at the first pulling member 41 and will not be elaborated on.

[0060] When the first tensioning member 41 is in contact with the thigh or calf, the first movable plate 461 can be driven by the pusher 47 to move, increasing and decreasing the tension of the first tensioning member 41 and the tension of the second tensioning member 42. The increased tension of the first tensioning member 41 and the decreased tension of the second tensioning member 42 cause the first tensioning member 41 to pull the second tensioning member 42, shifting the positions of the first and second tensioning members 41, 42 that were originally in contact with the limb. This causes the connecting member 5 and the massage block 7 to move, thus achieving a certain tensioning force on the limb by the first and second tensioning members 41, 42, while also causing the connecting member 5 and the massage block 7 to move. The movement of the massage block 7 is equivalent to a rod, plate, or block sliding with pressure on the limb, thereby achieving a massaging effect on the limb and simultaneously restraining the limb to the support device 1.

[0061] Before placing a limb between the first pull member 41, the second pull member 42, the first wrapping device 2, and the second wrapping device 3, the limb must be placed on the first wrapping device 2. The positions of the first support plate 21 and the second support plate 22 must then be adjusted so that the second wrapping device 3 on both the first support plate 21 and the second support plate 22 can contact the side of the limb. The operation method is as follows: the power member 28 drives the two third transmission members 27 toward and away from each other, thereby driving the two second movable plates 271 toward and away from each other. The third drive motor 272 and the second transmission wheel 274 on the second movable plate 271 then straighten the second transmission rope 273. The two second transmission ropes 273 then move toward each other, pushing the first push rod 241 and the second push rod 251 toward each other, thereby moving the second support plate 22 and the first support plate 21 toward each other. The third support plate 23 is made of elastic material to control the force exerted by the two second wrapping devices 3 against the side of the limb, preventing excessive force from causing discomfort and pressure on the limb. At the same time, the third drive motor 272 can also be used to drive the second transmission wheel 274 to rotate and adjust the length of the second transmission rope 273, thereby adjusting the force that brings the first supporting plate 21 and the second supporting plate 22 closer to each other, so as to adapt to limbs of different thicknesses.

[0062] In some embodiments, to allow the first and second carrier plates 21, 22 to return to their original positions when the two third transmission members 27 move away from each other, the third carrier plate 23 can be fixed to the abutment surface, thereby being fixedly connected to the second carrier plate 22. When the first and second carrier plates 21, 22 move away from and toward each other, the third carrier plate 23 slides within the receiving groove. Furthermore, the second transmission rope 273 is fixed to the first push rod 241 and the second push rod 251, thereby directly driving the first and second carrier plates 21, 22 to move toward and away from each other via the second transmission rope 273.

[0063] The third supporting plate 23 can also be slidably connected to the accommodating groove. A guide rod 26 and a spring 261 are provided in the accommodating groove. The spring 261 is slidably connected to the third supporting plate 23. The guide rod 26 is inserted into the third supporting plate 23 to guide the third supporting plate 23. The spring 261 is used to subject the third supporting plate 23 to a resetting elastic force, thereby also realizing the approach and distance between the first supporting plate 21 and the second supporting plate 22.

[0064] In some embodiments, the massage members 53 on the first inserting block 51 and the second inserting block 52 can massage the limbs. The massage members 53 on the first wrapping device 2 and the second wrapping device 3 can also massage the limbs.

[0065] During rehabilitation training, the two support devices 1 are rotated by the rotating member 8, thereby forcing the patient's limbs to move, or the patient uses force to move the limbs to overcome the gravity of the support device 1 for weight-bearing training and massage.

[0066] The pull rod 431 is rotatably connected to the support rod 432, and the pull rod 431 is fixedly connected to a group of first pull members 41. Specifically, the three first pull members 41 in a group of first pull members 41 are arranged in a linear array, with one first pull member 41 located in the middle of the pull rod 431, and the other two first pull members 41 are symmetrical about the first pull member 41 located in the middle. The rotating wheel 44 is the main power, so the pull rod 431 can rotate, thereby making it possible to make the three first pull members 41 in each group of first pull members 41 experience different tensions according to different leg shapes.

[0067] The second wrapping device 3 is provided with a plurality of guide wheel groups 31 for guiding the first pull member 41. The way in which the guide wheel group 31 and the guide member 6 guide the first pull member 41 is shown in the attached figure of the second wrapping device 3, mainly for achieving a change in the direction of force.
