Description

Lower Limb Fracture Knee Function Rehabilitation Device

technical field

The utility model relates to a medical device, in particular to a medical device for function rehabilitation of the fractured knee joint of the lower limb.

Background technique

At present, the lower limbs of the human body include the femur, tibia, and tibia, etc., and the fracture treatment generally goes through three stages. In the first stage of bed rest treatment, surgery or reduction and fixation of fractures are mostly treated with integrated traditional Chinese and Western medicine, so as to promote the formation of callus and make the fracture heal first. In the second stage, there are a large number of calluses at the fracture site, but you can’t move on the ground at this time, so as to avoid the weight on the legs. However, while taking drug treatment at this stage, an important link that cannot be ignored is to carry out effective treatment under the guidance of doctors. Exercise joint function to avoid ankylosis after the fracture heals. The third stage is the rehabilitation period, which is mainly to follow the doctor's advice and continue to exercise in order to facilitate the comprehensive recovery of joint functions. Then, some of the existing medical exercise equipment for joint recovery function are large-scale, and are limited to exercise after going to the ground; some are dedicated for athletes; There is not yet a special bed and lower limb fracture knee joint function rehabilitation device.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of rehabilitator that is suitable for lower extremity fracture and can carry out knee joint functional exercise on the bed after treatment.

In order to achieve the above purpose, the design scheme of the present utility model is: a functional rehabilitation device for fractured knee joints of lower limbs, including a bed frame, a thigh support board and a calf support board, wherein one end of the thigh support board is connected to the bed frame through a hinge. A knee support is provided at the hinged ends of the backing board and the shank backing board, a rolling wheel is provided at the lower end of the shank backing board, and a rolling groove is arranged on the top of the bed frame, and the rolling wheel rolls back and forth in the rolling groove.

A torsion spring is arranged inside the knee rest, and its two ends act on the thigh rest board and the calf rest board respectively.

The thigh rest and the calf rest are respectively composed of multiple sections.

A layer of massaging blocks is arranged on the thigh rest board, the calf rest board and the knee support.

Described bed frame is provided with a motor, and its driving wheel is connected with the lower end of calf support plate through traction rope, and forward rotation switch, reverse rotation switch are connected with its control circuit.

When a large number of calluses are formed in the fractured part of the lower limbs of the patient after treatment, the patient is asked to sit flat on the bed with his legs stretched out. The bed rest time is longer, and the knee joint cannot be bent to a large extent. The knee support of the rehabilitation device prevents the knee joint from being injured during the lifting activity. The torsion spring in the knee support makes the thigh rest and calf rest have an outward tension; the thigh rest and calf rest are composed of multiple sections, and the length of the thigh rest and calf rest can be adjusted according to the condition of the lower limbs Of course, those skilled in the art can also use other methods to realize the adjustment of the length of the backboard to adapt to lower limbs of different lengths. There is a layer of massage blocks on the thigh rest board, calf rest board and knee rest to prevent the muscles and blood vessels from becoming stiff due to the long-term inactivity of the lower limbs. Manipulate the forward rotation switch and reverse rotation switch of the motor to make the rehabilitation device work to exercise the knee joint.

The utility model has the characteristics of novel and simple structural design, low manufacturing cost, convenient clinical use and good use effect, and is suitable for large, medium and small hospitals and family beds.

In the figure: 1-lower limbs, 2-knee support, 3-torsion spring, 4-massage block, 5-rolling wheel, 6-rolling groove, 7-motor, 8-forward rotation switch, 9-reverse rotation switch, 10- Bed frame, 11-hinge, 12-thigh rest board, 13-calf rest board, 14-traction rope.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Fig. 1, a kind of lower limb fracture knee joint functional recovery device provided by the utility model includes a bed frame 10, a thigh support plate 12 and a calf support plate 13, wherein one end of the thigh support plate 12 is connected with the bed frame 10 through a hinge 11, Knee support 2 is provided at the hinged end of thigh prop 12 and shank prop 13, calf prop 13 lower ends are provided with rolling wheel 5, and bed frame 10 top is provided with rolling groove 6, and scroll wheel 5 rolls back and forth in rolling groove 6. The two ends of the torsion spring 3 in the knee support 2 act on the thigh resting plate 12 and the calf resting plate 13 respectively, so that the thigh resting plate 12 and the calf resting plate 13 have an outward tension; Board 13 is all to be made up of multiple sections respectively, can adjust the length of thigh back board 12 and shank back board 13 according to lower limb situation, adapts to the lower limbs 1 of different lengths. Thigh resting board 12, calf resting board 13 and knee support 2 are all provided with one deck massage block 4, in order to avoid lower limbs 1 not moving for a long time, muscle, blood vessel are stiff. A motor 7 is arranged on the bed frame 10 and is controlled by a forward switch 8 and a reverse switch 9. The driving wheel of the motor 7 is connected with the lower end of the calf support plate 13 by a traction rope 14 .

When the patient or the caregiver presses the forward rotation switch 8 by hand, the motor 7 rotates forward, and the driving wheel pulls the calf support plate 13 back through the traction rope 14, and at this moment the rolling wheel 5 will go back in the rolling groove 6 Rolling thereby raises the knee rest 2 ie raises the lower extremity 1 . On the contrary, when the patient or the caregiver pressed the reversing switch 9 by hand, the motor 7 reversed, the traction rope 14 was loosened, and the calf support plate 13 was supported outward by the effect of the torsion spring 3, at this moment the scroll wheel 5 would be rolling The groove 6 slides in and out so that the knee support 2 is lowered, that is to say, the lower limb 1 is lowered. Just reciprocating up and down in this way, and exercising again and again in this way, can achieve the purpose of its rehabilitation medicine.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model. But these corresponding changes and deformations should all belong to the scope of protection of the appended claims of the present utility model.
