DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10A bed rehabilitation device comprises a mobile base 1, and also comprises: an installation box 3 connected to the mobile base 1, wherein a rotating shaft 301 is rotatably connected in the installation box 3, a flywheel 302 is fixedly connected to the rotating shaft 301, and both ends of the rotating shaft 301 are fixedly connected to a rotating rod 303; a pedal 304 is rotatably connected to the rotating rod 303; a leg rest 5 is connected to the pedal 304, wherein one side of the leg rest 5 is symmetrically fixedly connected with an elastic strap 502, and the other side is symmetrically fixedly connected with a buckle 2 503 used in conjunction with the elastic strap 502, and both ends of the elastic strap 502 are provided with Velcro; an air bag 6 is arranged on the leg rest 5, a plurality of cavities 601 are equidistantly arranged in the air bag 6, and one side of the leg rest 5 is provided with an air inlet pipe 602 with the same number as the cavity 601, and the air inlet pipe 602 is communicated with the cavity 601.

[0033] A piston cylinder 8 is fixedly installed in the installation box 3, a piston disk 801 is slidably connected in the piston cylinder 8, a piston rod 802 is rotatably connected to the piston disk 801, a crankshaft 803 is fixedly connected to the rotating shaft 301, the crankshaft 803 is rotatably connected to the piston rod 802, a conduit 1 804 and a conduit 2 805 are fixedly connected to the piston cylinder 8, and the piston cylinder 8 is connected to the intake pipe 602 through the conduit 2 805.

[0034] The other side of the leg rest 5 is provided with exhaust pipes 603 , the same number as the cavities 601 , which are connected to the cavities 601 . Both the exhaust pipes 603 and the air inlet pipes 602 are provided with solenoid valves for adjusting the internal air pressure of each cavity 601 .

[0035] A restraining belt 305 is symmetrically fixedly connected to one side of the pedal 304 , and a buckle 306 used in conjunction with the restraining belt 305 is symmetrically fixedly connected to the other side. Velcro is provided at both ends of the restraining belt 305 .

[0036] A U-shaped block 2 is provided on both sides of the mobile base 1, and a screw rod 202 is threadedly connected to the U-shaped block 2, and a clamping block 201 is rotatably connected to the screw rod 202, and a sliding rod 204 is fixedly connected to the clamping block 201, and the sliding rod 204 is slidably connected to the U-shaped block 2, and a slider 205 is fixedly connected to the U-shaped block 2. A guide groove is opened on the mobile base 1, and the slider 205 is slidably connected in the guide groove.

[0037] It also includes a mounting base 101 which is lifted and connected to the mobile base 1 , on which an electric telescopic rod 307 is symmetrically fixedly mounted, and the mounting box 3 is fixedly connected to the telescopic end of the electric telescopic rod 307 .

[0038] A hydraulic telescopic rod 102 is fixedly installed in the mobile base 1 , and the telescopic end of the hydraulic telescopic rod 102 is fixedly connected to the mounting seat 101 .

[0039] When in use, first move the mobile base 1 to a suitable position beside the bed, then sleeve the U-shaped clamping block 2 on the edge of the bed, and then rotate the screw rod 202. The rotational motion of the screw rod 202 will be converted into a linear motion along its axial direction, so that the linearly moving screw rod 202 pushes the clamping block 201 to move until the clamping block 201 clamps the edge of the bed, thereby limiting and fixing the mobile base 1, preventing the mobile base 1 from shaking due to the movement of the patient's legs during the patient's leg rehabilitation training;

[0040] At the same time, according to the height of the bed where the patient is located, the hydraulic telescopic rod 102 is started, so that the mounting seat 101 can drive the pedal 304 and the leg support 5 on the mounting box 3 to rise or fall to a suitable height, so that the patient can place his feet and legs on the pedal 304 and the leg support 5, and then fine-tune the height of the mounting box 3 through the electric telescopic rod 307 to ensure that the pedal 304 and the leg support 5 are in a comfortable placement position for the patient's legs. After the adjustment is completed, the patient can put his feet on the pedal 304, and use the restraint belt 305 and the buckle 306 to fix the feet. At the same time, the patient can also use the Velcro to fix the feet. Adjust the tightness of the strap 305 so that the strap 305 can firmly fix the foot, ensuring that the foot fits tightly against the pedal 304 during the rehabilitation training, and the effect of the rehabilitation training will not be affected by the looseness of the foot. Then place the leg on the leg rest 5, pass the elastic strap 502 around the leg, fix it with the buckle 2 503, and adjust the tightness of the elastic strap 502 with Velcro to stably fix the leg on the leg rest 5. At the same time, the elastic strap 502 can also naturally stretch and contract according to the changes in the thickness of the leg, thereby reducing the discomfort caused by pressure on the leg.

[0041] When the patient starts leg rehabilitation training, the pedal 304 is driven to rotate around the rotating rod 303 through the flexion and extension movement of the leg. The rotation of the pedal 304 is transmitted to the leg support 5 through the multi-stage telescopic rod 501, so that the leg moves accordingly. During the exercise, the rotating shaft 301 rotates with the rotation of the pedal 304, driving the flywheel 302 to rotate. At the same time, the rotating shaft 301 drives the crankshaft 803 to rotate synchronously. When the crankshaft 803 rotates, the piston plate 801 is driven to make a linear reciprocating motion in the piston cylinder 8 through the piston rod 802. When the piston plate 801 moves out of the piston cylinder 8, the catheter can be used to 804 absorbs external gas into the piston cylinder 8, and then when the piston plate 801 moves into the piston cylinder 8, the squeezed gas can be discharged from the piston cylinder 8 through the second conduit 805, and filled into the airbag 1 6 through the air inlet pipe 602, so that the airbag 1 6 expands. The expanded airbag 1 6 can support and wrap the legs from multiple directions such as the bottom and side of the legs, ensuring the stability of the patient's leg position during the wheel training, reducing the training injury that may be caused by the shaking of the legs, and improving the safety of rehabilitation training. Both the conduit 1 804 and the conduit 2 805 are provided with a one-way valve;

[0042] like Figure 8 As shown, when the gas is filled into the airbag 6 through the air inlet pipe 602, since the airbag 6 is composed of multiple cavities 601, the airbag 6 can disperse the pressure required for fixing the leg into each cavity 601 through the air inlet pipe 602 connected to the cavity 601, thereby reducing the local pressure on the leg and improving the comfort of the patient;

[0043] like Fig. 9 As shown, since a plurality of cavities 601 are equidistantly arranged in the airbag 6, each cavity 601 has an independent air inlet pipe 602, and an electromagnetic valve is arranged on the air inlet pipe 602, and an exhaust pipe 603 is connected to the cavity 601, and an electromagnetic valve is also arranged on the exhaust pipe 603, and the opening and closing of these electromagnetic valves controls the inflow and outflow of gas in each cavity 601;

[0044] During the process of inflating the airbag 6, the opening and closing sequence and time of the electromagnetic valves on the air inlet pipes 602 of different cavities 601 are controlled to inflate a specific cavity 601. For example, the electromagnetic valve of the air inlet pipe 602 of a cavity 601 near a certain part of the leg is opened first, and the gas enters the cavity 601 to expand it. At this time, the airbag 6 at this part rises, and then the electromagnetic valve of the air inlet pipe 602 of this cavity 601 is closed, and the electromagnetic valve of the air inlet pipe 602 of another adjacent or other designated cavity 601 is opened, and the gas enters the new cavity 601. 01 is expanded, and the previously expanded cavity 601 may shrink because gas no longer enters or a certain degree of gas is discharged through the exhaust pipe 603, thereby causing the airbag 6 to fluctuate in different parts. Therefore, by controlling the inflation and exhaust sequence, time and gas flow between multiple cavities 601, it is possible to simulate various massage modes with different ups and downs and different intensities, such as simulating muscle contraction and relaxation movements, promoting leg blood circulation and muscle recovery, so as to meet different rehabilitation needs and improve the rehabilitation effect of the legs.

[0045] It should be noted that the second conduit 805 is a stretchable and shrinkable hose, so the second conduit 805 will not interfere with the rotation of the rotating rod 303.

[0046] Example 2: Reference Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 A bed rehabilitation device is basically the same as that of Example 1, and further, a groove is provided on the clamping block 201, a clamping plate 203 and an airbag 7 are arranged in the groove, one end of the airbag 7 is fixedly connected to the clamping plate 203, and the other end is fixedly connected to the inner wall of the groove, and an air supply pipe 703 is fixedly connected to the airbag 7, and the air supply pipe 703 is connected to the exhaust pipe 603;

[0047] When the gas in the cavity 601 is discharged from the airbag 1 6 through the exhaust pipe 603, the gas discharged from the airbag 1 6 will flow to the airbag 2 7 along the air supply pipe 703. A one-way valve is provided on the air supply pipe 703. When the airbag 2 7 expands by receiving the gas discharged from the airbag 1 6, it can push the clamping plate 203 to apply pressure in the direction of the bed edge, thereby enhancing the clamping force of the clamping block 201 on the bed edge, improving the stability of the device clamped and fixed on the bed edge, and preventing the device from shaking and affecting the effect of rehabilitation training. At the same time, the expanded airbag 2 7 can also play a role in buffering and shock absorption, reducing the vibration amplitude transmitted to the screw 1 202, thereby reducing the possibility of the screw 1 202 loosening due to vibration, and further improving the stability of the device clamped and fixed on the bed edge;

[0048] It should be noted that the air delivery pipe 703 is a stretchable and shrinkable hose, so the air delivery pipe 703 will not interfere with the rotation of the rotating rod 303.

[0049] The clamping block 201 is provided with a pressure relief pipe 1 701 connected with the airbag 2 7, a pressure relief valve is provided on the pressure relief pipe 1 701, and a pressure relief pipe 2 702 is fixedly connected to the pressure relief pipe 1 701, and a valve switch is provided on the pressure relief pipe 2 702; when the pressure inside the boosted airbag 2 7 is greater than the pressure relief value set by the pressure relief valve on the pressure relief pipe 1 701, the pressure relief valve automatically opens to release the pressure and discharge the excess gas, thereby keeping the air pressure inside the airbag 2 7 constant, preventing the airbag 2 7 from being damaged by excessive internal pressure due to excessive air intake;

[0050] When the device needs to be removed from the bedside, or the position of the device on the bedside needs to be adjusted, the gas in the airbag 2 7 will be discharged along the pressure relief pipe 1 701 and the pressure relief pipe 2 702 by opening the valve switch on the pressure relief pipe 2 702. At this time, the volume of the airbag 2 7 will be reduced, and its clamping force on the bedside will also be reduced, thereby facilitating the removal or position adjustment of the device.

[0051] Example 3: Reference Figure 5 , Figure 6 , a bed rehabilitation device, which is basically the same as the embodiment 1, and further, a damping block 4 is arranged in the installation box 3, a second screw rod 401 is rotatably connected to the damping block 4, a guide rod 402 is fixedly connected to the damping block 4, the guide rod 402 is slidably connected to the installation box 3, the second screw rod 401 is threadedly connected to the installation box 3, and the damping block 4 is located directly below the flywheel 302;

[0052] When the damping needs to be adjusted, the screw rod 401 is rotated. Due to the threaded connection between the screw rod 401 and the mounting box 3, the rotational motion of the screw rod 401 will be converted into linear motion along its axial direction, so that the linear motion of the screw rod 401 pushes the damping block 4 to move. When the damping block 4 is close to the flywheel 302, the resistance encountered by the flywheel 302 will increase. Conversely, when the damping block 4 is away from the flywheel 302, the resistance encountered by the flywheel 302 will decrease. Therefore, the resistance of the flywheel 302 can be adjusted according to the patient's demand for training intensity at different rehabilitation stages, thereby improving the training effect.

[0053] Example 4: Reference Figure 4 , Figure 7 , a bed rehabilitation device, which is basically the same as Example 1, and further, a multi-stage telescopic rod 501 is fixedly installed on the pedal 304, and the leg support 5 is fixedly installed on the telescopic end of the multi-stage telescopic rod 501; due to the difference in leg lengths of different patients, the multi-stage telescopic rod 501 is used to adjust the distance between the leg support 5 and the pedal 304, so that the leg support 5 can better adapt to the patient's leg length, thereby allowing the patient's calf to be naturally and comfortably supported.
