DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] The present invention provides a technical solution: a leg rehabilitation nursing device, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a nursing box 1, a load-bearing plate 12 is fixedly connected to the nursing box 1, a first sliding groove 33 is opened on the load-bearing plate 12, a support block 31 is slidably connected to the first sliding groove 33, a first rotating rod 32 is rotatably connected to the support block 31, both ends of the first rotating rod 32 are fixedly connected to connecting plates 22, each connecting plate 22 is fixedly connected to a leg support plate 2, an electric push rod 3 is fixedly connected in the first sliding groove 33, and the output end of the electric push rod 3 is fixedly connected to the support block 31, and a driving mechanism for driving the leg support plate 2 to perform rehabilitation care on the patient's legs is provided on the nursing box 1.

[0034] A height adjustment mechanism may be provided at the lower end of the nursing box 1 of the device. The height adjustment mechanism is an existing mechanism and is well known to those skilled in the art, so it will not be described in detail here.

[0035] The device is adjusted to be flush with the patient's bed by the height adjustment mechanism, and then the medical staff helps the patient to move so that the patient's calves move to the leg support board 2, and then the medical staff places the patient's two calves into the leg support board 2.

[0036] Driven by the driving mechanism, the leg support board 2 swings up and down reciprocatingly with the first rotating rod 32 as the center, so that the patient repeatedly performs straight leg raising and lowering training to exercise the patient's leg muscle strength and prevent the leg muscles from atrophying due to disuse, which will lead to weakness in walking on the ground in the later stage.

[0037] According to the patient's recovery level, the electric push rod 3 is started, so that the output end of the electric push rod 3 drives the support block 31 to slide, and the first rotating rod 32 and the connecting plate 22 on the support block 31 slide synchronously, so that the position of the first rotating rod 32 changes, thereby the swing amplitude and speed of the leg support board 2 are changed, so that the swing amplitude and speed of the leg support board 2 are determined according to the patient's recovery level. When the patient's recovery level is poor and the leg movement range is small, the amplitude of the leg support board 2 reciprocating up and down with the first rotating rod 32 as the center is reduced, and the speed of the up and down reciprocating swinging is synchronously slowed down. When the patient's recovery level is good and the leg movement range is large, the amplitude of the leg support board 2 reciprocating up and down with the first rotating rod 32 as the center is increased, and the speed of the up and down reciprocating swinging is synchronously accelerated, which not only ensures that the rehabilitation training care is effective for the patient, but also avoids the effect of secondary injury to the patient.

[0038] The leg support plate 2 is provided with fasteners 21 for fixing the patient's legs.

[0039] By providing the fastener 21 , the effect of fixing the patient's calf and the leg support board 2 is achieved.

[0040] The driving mechanism includes two support plates 11 fixedly connected to the nursing box body 1, each support plate 11 is rotatably connected to a hollow cylinder 26, each hollow cylinder 26 is fixedly connected to a crank 27, each crank 27 is fixedly connected to a support rod 28 at one end away from the hollow cylinder 26, each support rod 28 is rotatably connected to a ring 29, each connecting plate 22 is provided with a second sliding groove 23, and each support rod 28 is slidably connected to the corresponding second sliding groove 23 through the ring 29.

[0041] The driving mechanism also includes a motor frame 41 fixedly connected to the nursing box 1, the motor frame 41 is fixedly connected to the motor 4, and the output end of the motor 4 is fixedly connected to a rotating shaft 42, and the rotating shaft 42 cooperates with the hollow cylinder 26.

[0042] Start the motor 4 and the rotating shaft 42 rotates. Since the rotating shaft 42 cooperates with the hollow cylinder 26, the hollow cylinder 26 drives the crank 27 to rotate. Since the support rod 28 on the crank 27 is slidably connected to the second sliding groove 23 of the connecting plate 22 through the ring 29, and the connecting plate 22 rotates with the first rotating rod 32, the connecting plate 22 swings back and forth up and down with the first rotating rod 32 as the center.

[0043] By providing the collar 29, the effect of reducing friction is achieved.

[0044] When the patient's recovery degree is poor and the range of leg movement is small, the output end of the electric push rod 3 drives the support block 31 to slide away from the electric push rod 3, so that the position of the first rotating rod 32 is gradually close to the position of the hollow cylinder 26. Therefore, when the crank 27 drives the support rod 28 to rotate, the amplitude of the up and down reciprocating swing of the connecting plate 22 with the first rotating rod 32 as the center is reduced, and the speed of the up and down reciprocating swing is synchronously slowed down, thereby avoiding secondary injuries to the patient's legs due to intense rehabilitation training and affecting the rehabilitation effect.

[0045] When the patient's recovery is good and the range of leg movement is large, the output end of the electric push rod 3 drives the support block 31 to slide in the direction close to the electric push rod 3, so that the position of the first rotating rod 32 is gradually separated from the position of the hollow cylinder 26. Therefore, when the crank 27 drives the support rod 28 to rotate, the amplitude of the up and down reciprocating swing of the connecting plate 22 with the first rotating rod 32 as the center increases, and the speed of the up and down reciprocating swing becomes faster synchronously, ensuring that the rehabilitation training for the patient is effective and avoiding the situation that the rehabilitation training has little effect on the patient and affects the rehabilitation effect.

[0046] The second sliding groove 23 is provided with an auxiliary mechanism for assisting the ring 29 to slide in the second sliding groove 23. The auxiliary mechanism includes a first spring 24 fixedly connected in the second sliding groove 23. The end of the first spring 24 away from the second sliding groove 23 is fixedly connected with a slider 25. The slider 25 is slidably connected to the second sliding groove 23, and the slider 25 abuts against the ring 29.

[0047] The first spring 24 and the slider 25 are used to reset the auxiliary collar 29 and the support rod 28, thereby avoiding the collar 29 and the second sliding groove 23 on the connecting plate 22 from getting stuck or interfering, thereby affecting the patient's recovery effect.

[0048] Embodiment 2

[0049] The same as the first embodiment, furthermore: see Figure 1 , Figure 2 , Figure 6 and Figure 7 The hollow cylinder 26 is provided with a return acceleration mechanism adapted to the patient's leg rehabilitation. The return acceleration mechanism includes a connecting rod 43 fixedly connected to the hollow cylinder 26, a weight block 44 is fixedly connected to the connecting rod 43, a matching groove 46 is opened on the hollow cylinder 26, a clamping rod 45 is fixedly connected to the rotating shaft 42, and the clamping rod 45 is slidably connected to the matching groove 46.

[0050] When the rotating shaft 42 rotates, the clamping rod 45 thereon rotates synchronously. Since the clamping rod 45 is slidably connected with the matching groove 46 on the hollow tube 26, when the clamping rod 45 rotates to be vertical and facing downward, the ends of the clamping rod 45 and the matching groove 46 abut against each other, so that the hollow tube 26 rotates synchronously with the clamping rod 45. At this time, the leg support board 2 swings from bottom to top, driving the patient's legs to do straight leg raising training.

[0051] When the clamping rod 45 rotates to be vertical and faces upward, the weight block 44 is synchronously vertical and faces upward. Then, under the action of the gravity of the weight block 44, the weight block 44 drives the hollow tube 26 to cancel the cooperation with the clamping rod 45 and rotates downward quickly. At this time, the leg support board 2 swings from top to bottom, driving the patient's legs to do straight leg descent training, and the descent speed is faster than the raising speed, thereby further stimulating the leg muscles and accelerating the effect of leg muscle rehabilitation.

[0052] Embodiment 3

[0053] The same as the second embodiment, furthermore: see Figure 1 , Figure 2 and Figure 8Each leg support board 2 is provided with an ankle joint care mechanism for rehabilitation care of the patient's ankle joint, the ankle joint care mechanism includes a second rotating rod 51 and a belt 53, the second rotating rod 51 is rotatably connected to the leg support board 2, the second rotating rod 51 is fixedly connected to the foot support board 5, the second rotating rod 51 is fixedly connected to the second disc pulley 52, the first rotating rod 32 passes through the connecting plate 22, and one end of the first rotating rod 32 passing through the connecting plate 22 is fixedly connected to the first disc pulley 54, and the first disc pulley 54 and the second disc pulley 52 are connected through a belt 53.

[0054] When the leg board 2 swings up and down reciprocatingly with the first rotating rod 32 as the center, the second disc wheel 52 on the first rotating rod 32 rotates reciprocatingly synchronously. Since the second disc wheel 52 is connected to the first disc wheel 54 through the belt 53, the first disc wheel 54 drives the second rotating rod 51 to rotate reciprocatingly synchronously, so that the leg board 5 on the second rotating rod 51 rotates reciprocatingly.

[0055] When the leg support board 2 drives the patient to do straight leg raising training, the foot support board 5 synchronously rotates with the second rotating rod 51 as the center, so that the ankle joint moves synchronously, the ankle joint is rehabilitated and protected, and the patient's leg nerves are further stimulated, thereby improving the patient's leg rehabilitation efficiency. The size of the rotation angle is adapted to the patient's rehabilitation condition, avoiding injury to the patient's ankle joint.

[0056] When the leg support board 2 drives the patient to do straight leg lowering training, the foot support board 5 synchronously rotates with the second rotating rod 51 as the center, so as to relax and restore the patient's ankle joint, thereby achieving intermittent rehabilitation training for the patient's ankle joint, and coordinating with the straight leg raising and lowering training, improving the patient's leg rehabilitation efficiency.

[0057] Embodiment 4

[0058] The same as the third embodiment, furthermore: see Figure 1 , Figure 2 , Fig. 9 and Fig.10 Each nursing box 1 is provided with a massage care mechanism for massaging the patient's legs, the massage care mechanism includes a connecting block 63 fixedly connected to the nursing box 1, a piston cylinder 6 is fixedly connected to the connecting block 63, a sealing plug 67 is slidably connected to the piston cylinder 6, a piston rod 61 is fixedly connected to the sealing plug 67, a push rod 62 is fixedly connected to the piston rod 61, the push rod 62 is abutted against the weight 44, a plurality of slide grooves are provided on the leg support board 2, and a plurality of massage blocks 65 are placed through the slide grooves, an air supply pipe 64 is connected to the piston cylinder 6, one end of the air supply pipe 64 away from the piston cylinder 6 passes through the leg support board 2, and one end of the air supply pipe 64 passes through the leg support board 2 and is connected with a plurality of massage blocks 65.

[0059] The massage care mechanism also includes a second spring 66 sleeved on the piston rod 61 , and two ends of the second spring 66 are fixedly connected to the sealing plug 67 and the piston cylinder 6 respectively.

[0060] The massage block 65 is an air bag.

[0061] When the weight block 44 rotates, the push rod 62 abuts against the weight block 44 , and with the cooperation of the second spring 66 , the push rod 62 drives the piston rod 61 and the sealing plug 67 to slide back and forth along the piston cylinder 6 .

[0062] When the piston rod 61 and the sealing plug 67 slide along the piston cylinder 6 toward the air pipe 64, the gas in the piston cylinder 6 is transported to the massage block 65 through the air pipe 64, causing the massage block 65 to deform, thereby massaging the patient's legs on the leg support board 2; when the piston rod 61 and the sealing plug 67 slide along the piston cylinder 6 toward the direction away from the air pipe 64, the gas in the massage block 65 is transported to the piston cylinder 6 through the air pipe 64, thereby achieving the effect of intermittently massaging the patient's legs, promoting blood return to the legs, and clearing away the metabolic products of the leg muscles in time, which is beneficial to the absorption of local blood stasis and the early recovery of muscle injuries.

[0063] Working principle: When the leg rehabilitation nursing device is in use, a height adjustment mechanism can be set at the lower end of the nursing box 1 of the device. The height adjustment mechanism is an existing mechanism and is well known to those skilled in the art, so it will not be described in detail here.

[0064] The device is adjusted to be flush with the patient's bed by the height adjustment mechanism, and then the medical staff helps the patient to move so that the patient's calves move to the leg support board 2, and then the medical staff places the patient's two calves into the leg support board 2.

[0065] Driven by the driving mechanism, the leg support board 2 swings up and down reciprocatingly with the first rotating rod 32 as the center, so that the patient repeatedly performs straight leg raising and lowering training to exercise the patient's leg muscle strength and prevent the leg muscles from atrophying due to disuse, which will lead to weakness in walking on the ground in the later stage.

[0066] According to the patient's recovery level, the electric push rod 3 is started, so that the output end of the electric push rod 3 drives the support block 31 to slide, and the first rotating rod 32 and the connecting plate 22 on the support block 31 slide synchronously, so that the position of the first rotating rod 32 changes, thereby the swing amplitude and speed of the leg support board 2 are changed, so that the swing amplitude and speed of the leg support board 2 are determined according to the patient's recovery level. When the patient's recovery level is poor and the leg movement range is small, the amplitude of the leg support board 2 reciprocating up and down with the first rotating rod 32 as the center is reduced, and the speed of the up and down reciprocating swinging is synchronously slowed down. When the patient's recovery level is good and the leg movement range is large, the amplitude of the leg support board 2 reciprocating up and down with the first rotating rod 32 as the center is increased, and the speed of the up and down reciprocating swinging is synchronously accelerated, which not only ensures that the rehabilitation training care is effective for the patient, but also avoids the effect of secondary injury to the patient.

[0067] By providing the fastener 21 , the effect of fixing the patient's calf and the leg support board 2 is achieved.

[0068] Start the motor 4 and the rotating shaft 42 rotates. Since the rotating shaft 42 cooperates with the hollow cylinder 26, the hollow cylinder 26 drives the crank 27 to rotate. Since the support rod 28 on the crank 27 is slidably connected to the second sliding groove 23 of the connecting plate 22 through the ring 29, and the connecting plate 22 rotates with the first rotating rod 32, the connecting plate 22 swings back and forth up and down with the first rotating rod 32 as the center.

[0069] By providing the collar 29, the effect of reducing friction is achieved.

[0070] When the patient's recovery degree is poor and the range of leg movement is small, the output end of the electric push rod 3 drives the support block 31 to slide away from the electric push rod 3, so that the position of the first rotating rod 32 is gradually close to the position of the hollow cylinder 26. Therefore, when the crank 27 drives the support rod 28 to rotate, the amplitude of the up and down reciprocating swing of the connecting plate 22 with the first rotating rod 32 as the center is reduced, and the speed of the up and down reciprocating swing is synchronously slowed down, thereby avoiding secondary injuries to the patient's legs due to intense rehabilitation training and affecting the rehabilitation effect.

[0071] When the patient's recovery is good and the range of leg movement is large, the output end of the electric push rod 3 drives the support block 31 to slide in the direction close to the electric push rod 3, so that the position of the first rotating rod 32 is gradually separated from the position of the hollow cylinder 26. Therefore, when the crank 27 drives the support rod 28 to rotate, the amplitude of the up and down reciprocating swing of the connecting plate 22 with the first rotating rod 32 as the center increases, and the speed of the up and down reciprocating swing becomes faster synchronously, ensuring that the rehabilitation training for the patient is effective and avoiding the situation that the rehabilitation training has little effect on the patient and affects the rehabilitation effect.

[0072] The first spring 24 and the slider 25 are used to reset the auxiliary collar 29 and the support rod 28, thereby avoiding the collar 29 and the second sliding groove 23 on the connecting plate 22 from getting stuck or interfering, thereby affecting the patient's recovery effect.

[0073] When the rotating shaft 42 rotates, the clamping rod 45 thereon rotates synchronously. Since the clamping rod 45 is slidably connected with the matching groove 46 on the hollow tube 26, when the clamping rod 45 rotates to be vertical and facing downward, the ends of the clamping rod 45 and the matching groove 46 abut against each other, so that the hollow tube 26 rotates synchronously with the clamping rod 45. At this time, the leg support board 2 swings from bottom to top, driving the patient's legs to do straight leg raising training.

[0074] When the clamping rod 45 rotates to be vertical and faces upward, the weight block 44 is synchronously vertical and faces upward. Then, under the action of the gravity of the weight block 44, the weight block 44 drives the hollow tube 26 to cancel the cooperation with the clamping rod 45 and rotates downward quickly. At this time, the leg support board 2 swings from top to bottom, driving the patient's legs to do straight leg descent training, and the descent speed is faster than the raising speed, thereby further stimulating the leg muscles and accelerating the effect of leg muscle rehabilitation.

[0075] When the leg board 2 swings up and down reciprocatingly with the first rotating rod 32 as the center, the second disc wheel 52 on the first rotating rod 32 rotates reciprocatingly synchronously. Since the second disc wheel 52 is connected to the first disc wheel 54 through the belt 53, the first disc wheel 54 drives the second rotating rod 51 to rotate reciprocatingly synchronously, so that the leg board 5 on the second rotating rod 51 rotates reciprocatingly.

[0076] When the leg support board 2 drives the patient to do straight leg raising training, the foot support board 5 synchronously rotates with the second rotating rod 51 as the center, so that the ankle joint moves synchronously, the ankle joint is rehabilitated and protected, and the patient's leg nerves are further stimulated, thereby improving the patient's leg rehabilitation efficiency. The size of the rotation angle is adapted to the patient's rehabilitation condition, avoiding injury to the patient's ankle joint.

[0077] When the leg support board 2 drives the patient to do straight leg lowering training, the foot support board 5 synchronously rotates with the second rotating rod 51 as the center, so as to relax and restore the patient's ankle joint, thereby achieving intermittent rehabilitation training for the patient's ankle joint, and coordinating with the straight leg raising and lowering training, improving the patient's leg rehabilitation efficiency.

[0078] When the weight block 44 rotates, the push rod 62 abuts against the weight block 44 , and with the cooperation of the second spring 66 , the push rod 62 drives the piston rod 61 and the sealing plug 67 to slide back and forth along the piston cylinder 6 .

[0079] When the piston rod 61 and the sealing plug 67 slide along the piston cylinder 6 toward the air pipe 64, the gas in the piston cylinder 6 is transported to the massage block 65 through the air pipe 64, causing the massage block 65 to deform, thereby massaging the patient's legs on the leg support board 2; when the piston rod 61 and the sealing plug 67 slide along the piston cylinder 6 toward the direction away from the air pipe 64, the gas in the massage block 65 is transported to the piston cylinder 6 through the air pipe 64, thereby achieving the effect of intermittently massaging the patient's legs, promoting blood return to the legs, and clearing away the metabolic products of the leg muscles in time, which is beneficial to the absorption of local blood stasis and the early recovery of muscle injuries.

[0080] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
