Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of many poses lower limb rehabilitation training machine
Device people.
Background technology
The lower limb paralysis patient populations being caused by apoplexy, spinal cord injury and brain trauma at present is very big, presents
Ascendant trend.Lower limb paralysis patient, after the symptomatic treatment of acute stage, generally requires through longer
The rehabilitation of phase, to recover the lower extremity motor function of patient.Kinesiatrics is lower limb rehabilitation treatment
Common method.Traditional rehabilitation training is manually to be driven patient's lower limb to carry out training by therapist,
Subjectivity is big, waste time and energy, and effect is not ideal enough.Healing robot automates, accurately as one
Change, intelligentized Medical Devices, continue providing, have very strong advantage in terms of quantitative rehabilitation training,
Can effectively make up the deficiency of Traditional Rehabilitation treatment method, have broad application prospects.
It in clinical rehabilitation training, is generally directed to the different rehabilitation stage different training attitudes of employing and rail
Mark is to obtain preferable rehabilitation efficacy.For early stage patient, prone position is mostly used to carry out passive exercise,
Purpose is to prevent muscular atrophy, minimizing complication;And rehabilitation patient in mid-term, be gradually from prone position transition
To stance, adapt to midstance, at this time, it may be necessary to consider to overcome postural hypotension problem;For health
Multiple later stage patient, patient's lower limb have had certain muscular strength, it may be considered that combine loss of weight system and overcome
Body weight carries out passive or active gait training, enables the patient to realize early independent rows
Walk, recover activity of daily living.Simultaneously for the patient of early metaphase, often use the treadmill of sitting posture
Training.This training method uses fairly simple rehabilitation treadmill it is achieved that it trains cost relatively
Low, training set-up procedure is also very fast, therefore adopts and can carry out higher-strength and the frequency in this way
Rehabilitation training.At present, rehabilitation treadmill is widely used in the Rehabilitation Training in Treating of lower limb paralysis patient.
But, existing recovery robot system, mostly for the specific instruction of one training attitude design
Practice track, it is difficult to meet the training demand in paralysed patient different rehabilitation stage simultaneously;It is difficult to based on same
Platform, same standard, be optimized design to the prescription of rehabilitation training, it is thus achieved that optimum rehabilitation efficacy.
Content of the invention
For problem above, the present invention provides a kind of Multi-position lower limb rehabilitation training robot, this rehabilitation
Image training robot can provide sleeping, sit, the rehabilitation training of the many attitude such as stand;Can provide and human body
Naturally walking bionics gait training closely;And multiple training methods such as master is passive can be provided.
The present invention proposes a kind of Multi-position lower limb rehabilitation training robot, this many poses lower limb rehabilitation training
Robot includes robot base 1-1 and two modules of training bed.
Described robot base 1-1 is the support base of Multi-position lower limb rehabilitation training robot, its end
Portion is mounted with roller, for the movement of Multi-position lower limb rehabilitation training robot;Simultaneously described robot
Pedestal 1-1 is mounted with a set of bed body guiding mechanism, and this bed body guiding mechanism props up support component 1-8 by bed body
Hinged with the bed body framework 1-7 of described training bed, for described training bed angle is adjusted, with
The attitude of trainer when changing training.
Described training bed mainly includes leg mechanism 1-2, seat 1-4, seat width guiding mechanism, people
Body gravity centre adjustment mechanism, back cushion 1-5, back cushion framework 5-1, squab angle guiding mechanism, bed body framework
1-7 and loss of weight system 1-6.
Described leg mechanism 1-2 includes that hip, knee, three joints of ankle and large and small leg two overlap linkage,
For fixing trainer's lower limb, and supplemental training person's lower limb carry out training.
Described seat 1-4 takes one's seat for trainer during sitting posture training, supports trainer's weight.
Seat 1-4 is fixedly arranged on described seat width guiding mechanism, and described seat width guiding mechanism is used
In the distance adjusting between two set leg mechanism 1-2, to adapt to the build of different trainer;Described seat
Chair width adjusting mechanism is installed on described gravity center of human body's guiding mechanism, described gravity center of human body's guiding mechanism
For the position of adjusting training person's center of gravity real-time during gait training, center of gravity when simulation human body natural walks
Change up and down;Described seat 1-4 both sides are respectively mounted with a set of armrest 1-3, are used for training process
In provide hand support for trainer.
Trainer's upper body weight is supported when back cushion 1-5 is for prone position training.Described back cushion 1-5 is fixedly arranged on
Back cushion framework 5-1 front.Described back cushion framework 5-1 one end is hinged with described bed body framework 1-7.
Described squab angle guiding mechanism is installed on described back cushion framework 5-1 and described bed body framework 1-7
Between, it is used for when sitting posture or the training of prone position state adjusting the angle of back cushion, to improve the comfort level of training.
Loss of weight system 1-6 is driven by loss of weight system drive motor 4-11, is installed on back cushion framework 5-1's
(in this robot device, each parts are all with close trainer side as front, away from trainer at the back side
Side is the back side), for the some or all of body weight of balance training person.
The beneficial effects of the present invention is:
(1) bed body guiding mechanism, the design of squab angle guiding mechanism are passed through, it is achieved that based on together
One equipment realizes crouching, sits, the rehabilitation training of the many attitude such as stand;
(2) thigh and calf length, the seat width of described leg mechanism 1-2 are all adjustable, can meet
The training demand of different building shape trainer;
(3) loss of weight system is driven by motor, can accurately adjust loss of weight pulling force size continuously, to fit
Answer the recovery of trainer's lower limbs strength in rehabilitation process, provide just right strength to assist;
(4) loss of weight system, gravity center of human body's guiding mechanism and leg mechanism 1-2 cooperate, Ke Yishi
The now bionics gait close to human body natural's walking;
(5) angle of training bed can adjust continuously, disclosure satisfy that trainer overcomes body in rehabilitation mid-term
Position property hypotensive training demand;
(6) Chair back cushion angle can adjust continuously, disclosure satisfy that trainer uses at rehabilitation early metaphase
Prone position or sitting posture carry out the demand of lower limb rehabilitation training, can also improve the comfort level of training.
