Description
Technical field
The present invention relates to the technical fields of medical rehabilitation apparatus, in particular to knee joint automatic control plint.
Background technique
Clinically the training of knee articulation degree is mostly rehabilitation therapist's tact training at present, and orthopaedics postoperative patient rehabilitation week
Phase is long, and often functional rehabilitation needs several weeks or several months, if every patient allows rehabilitation therapist to resume training for a long time, produces for a moment
Raw expensive expense, two can occupy resource for a long time, therefore self-service reconditioning training equipment is necessary.
At present clinically widely used CPM (continuing joint passive activity device) price costly, and limbs debugging compared with
For complexity, patient voluntarily uses more difficulty, moreover, CPM can only be used under clinostatism, can be used for lower limb postoperative early stage, can
With prevention of knee adhesion, but the effect of the joint for having occurred and that adhesion is minimum, and the patient of knee stiffness is instructing
Drawing-off is needed to separate joint capsule when practicing, CPM is unable to complete under clinostatism.
Summary of the invention
The invention is intended to provide knee joint automatic control plint, to solve the self-service trained equipment valence of existing knee articulation degree
Lattice valuableness is unfavorable for the problem of promoting.

Sense of jolting in the process, to improve the comfort of the present apparatus；Fixing axle 7, drive shaft 8 and third driven shaft 14 are located at same
On straight line, and the axial line of two fixing axles, 7, two drive shafts 8 and two third driven shafts 14 is respectively superposed, and ensures that
Its synchronism moved improves the stability of this plint.Drive shaft 8 is slidably connected in the slideway of fixed block 5, drive shaft
8 are located on the motion profile of cam 6, guide rod 15 are connected between two drive shafts 8, guide rod 15 can ensure that drive shaft 8
Movement velocity is consistent, maintains the stationarity in 14 lifting process of third driven shaft, and after can also driving by guide rod 15
The drive shaft 8 of side is mobile, realizes the reasonable utilization of micromotor kinetic energy, improves utilization rate.
In the present embodiment, when patient needs to do knee sprung training, patient is first sitting on seat plate 2 and opens micro electric
Machine, minitype motor driving cam 6 rotates and the drive shaft 8 of front side is moved up at this time, and the drive shaft 8 of front side moves up
Can drive 8 synchronizing moving of drive shaft of rear side by guide rod 15 afterwards, and drive shaft 8 it is mobile after drive the second drive rod 11 to
Upper movement, the second drive rod 11 passes through first driven shaft 10 after moving up and second driven shaft 12 drives 9 He of the first drive rod
Third drive rod 13 moves up, and drives the first drive rod 9, second when drive shaft 8 drives the second drive rod 11 mobile at this time
Drive rod 11 moves up, and two the first drive rods 9 and two the second drive rods 11 generate upward push away because close to each other
Power, so that first driven shaft 10 and second driven shaft 12 be driven to move up, and because the length of the first drive rod 9, first from
The length of the second drive rod 11 between moving axis 10 and drive shaft 8 is respectively less than second between drive shaft 8 and second driven shaft 12
The length of drive rod 11, therefore the second drive rod 11 between the length, first driven shaft 10 and drive shaft 8 of the first drive rod 9
Length be not less than drive shaft 8 compared with the length of the second drive rod 11 between second driven shaft 12, this setting is because of first
The angle of first drive rod 9 and the second drive rod 11 increases on driven shaft 10, so that the movement that the second drive rod 11 is upward
Distance increases.
When second driven shaft 12 drives third drive rod 13 to move up, third drive rod 13 pushes third driven at this time
Push plate 16 on axis 14 is mobile, and it is mobile to push seat plate 2 after push plate 16 and the contact of seat plate 2, so that the lifting of seat plate 2 is realized,
So that this plint can be suitably used for the different patient of height；And in the process of moving since second driven shaft 12 is slidably connected
In sliding slot, to further increase the stationarity in lifting process.
Micromotor is closed after the height that patient regulates plint, two stabilizer blades of patient just can touch ground at this time
Face；When patient need to carry out bending the knee trained, patient will need the foot of training to be put into corresponding foot guard plate 4, then with another
One stabilizer blade is as impetus and starts lower moulded rod 18, and compression bar 18 is begun to move up around rotation axis 17 at this time, thus by leading
Messenger 19 drives pedal 3 to be moved to the left, at this time foot with the movement of pedal 3 and gradually buckling, to realize to kneed
Buckling training；And in the moving process of pedal 3, different training strength can be selected according to the state of an illness of patient, works as patient
After the intensity for selecting training, two levers 20 up and down of 18 position of compression bar are turned to the motion profile of compression bar 18 at this time
On, to realize the limitation to 18 position of compression bar and secure trained intensity, the labor intensity of patient is reduced, is convenient for patient
It is self-service to be trained.And two levers 20 of about 18 compression bar can also play the role of protection to compression bar 18, avoid compression bar 18
Secondary injury is caused to patient when suddenly due to external force there is a situation where moving up or down, to improve patient's
Safety.It can be rotated lever 20 after patient's training and be lifted up compression bar 18, effect of the pedal 3 in self gravity at this time
Lower reset.
If patient does not need to carry out the training of kneed buckling, by by foot be placed on 4 left side of foot guard plate and with foot guard plate 4
It offsets, then the restraining of 4 two sides of foot guard plate is strapped on the shank (tibiofibula) of patient, so that the foot of patient is fixed on
On pedal 3, then make seat plate 2 increase by opening micromotor, to increase kneed gap, enable patient into
The training of row traction separation joint capsule, increases the function of plint；And this plint structure is simple, makes convenient for extensive
It makes, so that product cost greatly reduce, is suitable for ordinary people.
The above are merely the embodiment of the present invention, the common sense such as well known specific structure and/or characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific embodiment can be used for explaining the content of claim.
