In order to prevent the leg muscles of patients with lower limb paralysis from atrophy, the prior art mostly adopts exoskeleton joint movement equipment to flex and extend the knee joint of the patient to achieve the purpose of joint movement.

[0003] The exoskeleton joint motion device needs to be connected to the lower limbs of a paralyzed patient through a fixing part. Since the change in blood filling degree in the muscles during leg flexion and extension will cause the leg circumference to change, in order to adapt to the change in leg circumference during knee flexion and extension, the fixing parts of the exoskeleton joint motion device in the prior art are mostly made of elastic materials. After the fixing parts made of elastic materials are connected to the lower limbs of the human body, they can better adapt to the changes in leg circumference and always fit the skin. However, the fixing parts made of elastic materials will also always exert radial pressure on the muscles and skin, which will not only hinder blood circulation, but may also cause deeper marks on the skin. In addition, since the fixing parts are attached to the skin, the sweat produced by the contact part of the fixing parts with the skin is difficult to be discharged into the air, and a large amount of sweat will gather in the marks, which may cause infection.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 4 A muscular atrophy prevention nursing device comprises an electric cylinder 2 and two hinged plates 1, the two hinged plates 1 are hinged together, the two ends of the electric cylinder 2 are hinged on the two hinged plates 1 respectively, a connecting structure for connecting human limbs is arranged on the hinged plate 1, the connecting structure comprises a circular ring shell 3 with a thin-wall structure and a circular ring-shaped inner lining plate 5, the inner lining plate 5 is rotatably mounted with a plurality of rotating shafts 7 in the radial direction, the rotating shaft 7 is connected to the circular ring shell 3, and a fan blade 8 is fixed to the rotating shaft 7, and massage structures are arranged on both sides of the inner wall of the inner lining plate 5 to massage the human limbs.

[0025] When the device is in use, the two inner lining plates 5 of the connection structure are respectively placed on the thigh and calf of the patient, and the two hinged plates 1 are driven to rotate by the telescopic movement of the electric cylinder 2, thereby driving the patient's knee joint to flex and extend. During the working process, the rotating shaft 7 drives the fan blades 8 to rotate, and the inner lining plate 5 is provided with a through hole 501. When the fan blades 8 rotate, the air between the inner lining plate 5 and the leg is sucked, and the sweat produced by the leg is sucked out together with the air, thereby ensuring that the leg skin is always kept dry.

[0026] like Figure 5-Figure 10The massage structure includes an annular cylinder 9, an annular piston 10 is slidably mounted in the cylinder 9, the piston 10 is fixedly connected to an annular connecting plate 11, a notch 21 is provided on the connecting plate 11, an eccentric wheel 12 is fixedly connected to the rotating shaft 7, and the eccentric wheel 12 is slidably mounted in the notch 21. An annular joint 14 is rotatably mounted on the cylinder 9, a plurality of air pipes 15 are radially connected to the joint 14, a slide pipe 16 is slidably mounted in the air pipe 15, a housing 18 is fixedly mounted on the slide pipe 16, the slide pipe 16 is connected to the housing 18, an ellipsoid 19 with a thin-walled structure is rotatably mounted on the housing 1, the housing 18 is connected to the inside of the ellipsoid 19, a plurality of air bags 20 are fixedly mounted on the outer wall of the ellipsoid 19, the air bags 20 are connected to the inside of the ellipsoid 19, and a tension spring 17 is provided on the air pipe 15 to apply elastic force to the slide pipe 16.

[0027] During the rotation of the rotating shaft 7, the eccentric wheel 12 is driven to rotate. Since the eccentric wheel 12 is located in the slot 21, the connecting plate 11 is driven to perform linear reciprocating motion along the axial direction through the slot 21 during the rotation of the eccentric wheel 12. During the linear reciprocating motion, the connecting plate 11 drives the two pistons 10 to move synchronously.

[0028] by Fig. 9 and Fig.10 For example, the piston 10 in the figure is located on the left and right sides of the connecting plate 11;

[0029] If the connecting plate 11 moves to the left in the figure:

[0030] The leftward movement of the left piston 10 will compress the air in the left cylinder 9, increasing the air pressure inside the left cylinder 9. Since the cylinder 9 is connected to the trachea 15, the air pressure inside the trachea 15 will also increase. Under the action of the air pressure, the slide tube 16 will overcome the elastic force of the tension spring 17 and move downward. The downward movement of the slide tube 16 will drive the shell 18 to move downward, and the downward movement of the shell 18 will drive the ellipsoid 19 downward. The downward movement of the ellipsoid 19 will make itself and the air bag 20 abut against the skin of the leg, so that the ellipsoid 19 and the air bag 20 are used to clamp and fix the device on the leg. Moreover, since the ellipsoid 19 is connected to the slide tube 16 through the shell 18, and the slide tube 16 is connected to the trachea 15, when the air pressure in the trachea 15 increases, the air pressure inside the ellipsoid 19 will also increase. The increase in the air pressure inside the ellipsoid 19 will cause the air bag 20 to expand, thereby squeezing and massaging the legs and improving the blood circulation speed of the legs.

[0031] Similarly, when the connecting plate 11 in the figure moves to the right, the ellipsoid 19 on the left is reset, and the ellipsoid 19 and the airbag 20 on the right can squeeze and massage the leg while clamping and fixing it to the leg, thereby improving the blood circulation speed of the leg.

[0032] Based on the above description, during the linear reciprocating motion of the connecting plate 11, the device switches the two ellipsoids 19 on the left and right sides to clamp and fix the legs, and the skin at the fixed position can also be exposed during the clamping and fixing.

[0033] Compared with the prior art in which the skin at the fixed part of the fixing part is always covered, the present device achieves the purpose of exposing the skin at the fixed part by switching the working states of the left and right ellipsoids 19, so that the sweat produced by the skin at this position can be smoothly discharged into the air, reducing the probability of skin infection due to sweat.

[0034] like Figure 4 As shown, end gears 13 are rotatably mounted on both sides of the inner lining plate 11 , a gear 6 is fixedly connected to the rotating shaft 7 , the end gear 13 matches the gear 6 , and the air pipe 15 is fixedly connected to the end gear 13 .

[0035] The gear 6 and the two end face gears 13 are meshed with each other. A small motor 4 is provided on the annular shell 3. A driving wheel 401 is installed on the output shaft of the small motor 4. The driving wheel 401 abuts against the end face gear 13, so that the small motor 4 can drive the end face gear 13 to rotate through the driving wheel 401, thereby making the meshing gear 6 and the two end face gears 13 rotate at the same time.

[0036] Since the trachea 15 is fixedly connected to the end face gear 13, when the end face gear 13 rotates, it will drive the trachea 15 to revolve around the axis of the annular shell 3, so that the ellipsoid 19 revolves around the axis of the annular shell 3. Since the ellipsoid 19 rests on the skin of the leg, it will roll on the skin of the leg during the revolution, so that the airbag 20 on the ellipsoid 19 can perform a surrounding massage on the leg, thereby improving the quality of the massage.

[0037] Working principle and workflow:

[0038] S1: First, two annular shells 3 are respectively placed on the thigh and calf of the patient, and then the electric cylinder 2 is started. The two hinged plates 1 are driven to rotate through the telescopic movement of the electric cylinder 2, thereby driving the patient's knee joint to flex and extend.

[0039] S2: Start the small motor 4. After the small motor 4 is started, the gear 6 and the two end gears 13 rotate.

[0040] S3: When the gear 6 rotates, it drives the shaft 7 to rotate, and the rotation of the shaft 7 drives the blades 8 and the eccentric wheel 12 to rotate, wherein:

[0041] Regarding the fan blades 8: during the rotation of the fan blades 8, the air can be sucked so that the sweat produced on the skin is sucked into the air through the through holes 501 on the inner lining plate 5 and the flow channel 301 on the annular shell 3 to prevent the sweat from accumulating.

[0042] For the eccentric wheel 12: during the rotation of the eccentric wheel 12, since the eccentric wheel 12 is located in the slot 21, the connecting plate 11 will be driven to perform linear reciprocating motion along the axial direction through the slot 21. During the linear reciprocating motion, the connecting plate 11 will drive the two pistons 10 to move synchronously. The moving direction of the pistons 10 can change the size of the air pressure inside the two cylinder bodies 9, thereby switching the size of the air pressure in the two cylinder bodies 9 back and forth through the reciprocating linear motion of the connecting plate 11.

[0043] S4: The change of the internal air pressure of the cylinder 9 will result in the following states:

[0044] When the air pressure inside the cylinder 9 increases: since the cylinder 9 is connected to the trachea 15, the air pressure inside the trachea 15 will also increase. Under the action of the air pressure, the slide tube 16 will overcome the elastic force of the tension spring 17 and move downward. The downward movement of the slide tube 16 will drive the shell 18 to move downward, and the downward movement of the shell 18 will drive the ellipsoid 19 downward. The downward movement of the ellipsoid 19 will make itself and the air bag 20 press against the skin of the leg, so that the ellipsoid 19 and the air bag 20 are used to clamp and fix the device on the leg. Moreover, since the ellipsoid 19 is connected to the slide tube 16 through the shell 18, and the slide tube 16 is connected to the trachea 15, when the air pressure in the trachea 15 increases, the air pressure inside the ellipsoid 19 will also increase. The increase in the air pressure inside the ellipsoid 19 will cause the air bag 20 to expand, thereby squeezing and massaging the legs and improving the blood circulation rate in the legs.

[0045] When the air pressure inside the cylinder 9 decreases: the ellipsoid 19 will perform a reset movement during the above process.

[0046] S5: During the rotation of the end face gear 13, since the air pipe 15 is fixedly connected to the end face gear 13, the rotation of the end face gear 13 will drive the air pipe 15 to revolve around the axis of the annular shell 3, causing the ellipsoid 19 to revolve around the axis of the annular shell 3. Since the ellipsoid 19 rests on the skin of the leg, it will roll on the skin of the leg during the revolution, so that the air bag 20 on the ellipsoid 19 can perform a surrounding massage on the leg, thereby improving the quality of the massage.

[0047] Compared with the prior art, the present device achieves the purpose of exposing the skin of a fixed part by switching the working states of the left and right ellipsoids 19, so that the sweat produced by the skin at that part can be sucked by the fan blades 8 and discharged into the air, reducing the probability of skin infection due to sweat.

[0048] The end face gear 13 makes the ellipsoid 19 roll and revolve around the legs at the same time, and the airbags 20 on the ellipsoid 19 perform surrounding massage on the legs, thereby improving the blood circulation speed of the legs.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
