[0025] Please refer to Figures 1-8The application provides an auxiliary movement device for preventing lower limb thrombus, which comprises a base 1, an elbow mechanism 3 is arranged on the base 1, the elbow mechanism 3 comprises a sliding block 35, a first fixed plate 30 fixed to one end of the base 1 and a second fixed plate 34 fixed to the other end of the base 1, a first elbow part 31 is rotatably arranged on the first fixed plate 30, the other end of the first elbow part 31 is connected with a second elbow part 32 through a shaft pin, the other end of the second elbow part 32 is connected with the sliding block 35, the sliding block 35 slides in a sliding groove 6 arranged on the base 1, an adapter 5 is arranged at the connection position of the first elbow part 31 and the second elbow part 32, and the adapter 5 is movably connected with a supporting pad 2 arranged on the second fixed plate 34 through the adapter 5, and a lead screw 36 is arranged on the second fixed plate 34 and is screwed with the sliding block 35.

[0026] The sliding block 35 is driven to slide in the sliding groove 6 by the lead screw 36, so that the two elbow parts make upward arching movement and downward flattening movement on the base 1; when the knee joint of a user is buckled on the supporting pad 2, the user's leg is driven to arch and flatten by the elbow mechanism 3, so as to facilitate the movement of the user's leg and reduce the formation of thrombus in the user's leg; based on the above, compared with the prior art, the device has a more ingenious structure, the patient's leg can be subjected to dorsiflexion movement by using the device, so that the purpose of preventing thrombus is achieved, in addition, the patient's lower limb can be moved within a certain range through simple operation, so that the patient's lower limb can be exercised, and finally the rehabilitation effect of the patient is effectively improved. In addition, the device has simple structure, small space occupation and is more suitable for use in hospitals.

[0027] In order to facilitate the disassembly and assembly of the supporting pad 2, the middle part of the adapter 5 is connected with a plug pin 7 arranged on the back of the supporting pad 2 through a plug hole 50.

[0028] Since the two ends of the adapter 5 are also provided with through holes 51, and the shaft pin rod 37 passes through the through holes 51 and the connection position of the first elbow part 31 and the second elbow part 32, the adapter 5 is fixed at the connection position of the first elbow part 31 and the second elbow part 32. Therefore, the shaft pin rod 37 can realize the assembly and rotation of the two elbow parts, and the adapter 5 can be conveniently installed on the elbow mechanism 3.

[0029] Further, the shaft pin rod 37 and the plug pin 7 are both provided with limiting protrusions 38 on the circumferential surface, and the through holes 51 and the plug hole 50 are both provided with limiting grooves 52 matched with the limiting protrusions 38 on the inner wall surface. Therefore, the problem of axial rotation of the adapter 5 at the connection position of the two elbow parts can be avoided, so that when the supporting pad 2 is installed, the stability of the supporting pad 2 during use can be ensured.

[0030] On the basis of the above scheme, since the one side of the first elbow part 31 facing the second elbow part 32 is provided with the convex point 311, and the one side of the second elbow part 32 facing the first elbow part 31 is provided with the concave hole 310, therefore, when the first elbow part 31 and the second elbow part 32 produce vibration in the process of arching or flat relaxing, the effective vibration massage of the lower limbs of the patient is achieved, so as to achieve the purpose of promoting the blood circulation of the lower limbs of the patient.

[0031] Further, since the number of the convex point 311 and the concave hole 310 is equal; wherein a plurality of the convex point 311 is circumferentially arrayed on the first elbow part 31, and a plurality of the concave hole 310 is circumferentially arrayed on the second elbow part 32, therefore, when one convex point 311 enters the corresponding concave hole 310, the vibration occurs once, since the number of the concave hole 310 and the convex point 311 is more, so as to improve the vibration frequency of the elbow mechanism 3, therefore, the effective vibration massage of the lower limbs of the patient is further achieved, so as to achieve the purpose of promoting the blood circulation of the lower limbs of the patient.

[0032] Since the second fixed plate 34 is further provided with the connecting hole 33, therefore, the second fixed plate 34 can be fixed on the base 1 by the bolt passing through the connecting hole 33, and the servo motor can be installed on the second fixed plate 34 by the bolt passing through the fixed seat of the servo motor and connected with the lead screw 36, so as to make the device realize the automatic arching action and flat relaxing action by controlling the start of the servo motor.

[0033] Further, since the one end of the lead screw 36 located outside the second fixed plate 34 is provided with the driving part 39, therefore, the medical staff can manually promote the rotation of the driving part 39 to promote the elbow mechanism 3 to complete the arching action or the flat relaxing action.

[0034] Further, since the driving part 39 is connected with the driving wheel 4, therefore, the power output of the user during rotation can be reduced.

[0035] In the above manner, the device can realize automatic control and manual control, and the overall structure of the device is relatively compact, and the user can make the elbow mechanism 3 complete the arching action and the flat relaxing action by placing on the bed and rotating the driving wheel 4, further reducing the use cost of the device and facilitating the nurses to move the device.

[0036] In addition, since the one side of the support pad 2 away from the base 1 is provided in the shape of a circular arc, therefore, the user's leg is more comfortable after being placed; in addition, the support pad 2 and the adapter 5 are easy to disassemble and assemble, therefore, the user can select the support pad 2 with different materials; wherein the material of the support pad 2 can be silica gel material or sponge material.

[0037] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the described embodiments. Various changes, modifications, replacements, and variations of the embodiments can be made by those skilled in the art without departing from the principles and spirit of the present application, and still fall within the scope of the present application.
