Present embodiment is a paralytic upper limb function recovery device that can supply the left hand passive exercise, and the position of left hand on the rehabilitation device represented in the double dot dash line among Fig. 1.Be used for the rehabilitation device of the right hand, its structure is left-right symmetric with it.

From Fig. 1 and Fig. 2, see the back and forth bent mechanism of opening up of finger and wrist is positioned on the leftmost position, its structure can be seen from Fig. 3 and Fig. 4, upper boom 911, lower beam 913, two parallel guide rod 914 have been comprised on the framework 91 that it contains, last bridge on the support 5 of decelerator 3e, its end and carriage 6 affixed one; In the activity box 92 with two groups of rollers 93 that can make its slippage on the guide rod 914 of framework, its top by double-screw bolt 96 affixed one its in addition end be connected cable wire 98 on the nut 3d1 of leading screw and nut mechanism so that activity box can be in the guide rod slippage of the drive lower edge of leading screw and nut mechanism framework.The resetting-mechanism of activity box is an elastic force cloth 94, and an end of this elastic force cloth is fixed on the lower beam 913 of framework, and in addition the bar 921 that fixedly rolls walked around on roll sleeve 912 on the framework and the activity box of end is fixed in below the pressing plate 95 on the activity box.Also affixed one can be impelled the hands that is held up by it to carry out crooked holder hands cloth 97 with formed triangle nest N in its motor process between activity box and the framework, and an end of this cloth is fixed on the upper boom 911 of framework, and end is fixed on the pressing plate 95 of activity box in addition.The position of hands is represented in double dot dash line among Fig. 4 on the holder hands cloth.

Also can see the mechanism that can make the reciprocal rotation of arm in this utility model in Fig. 1 and Fig. 2, this mechanism comprises micro machine 2, and by the gear reduction unit 3e of this micro motor for driving, carriage 6 directly is fixed on the output shaft of this decelerator.

The mechanism that the reciprocal song of arm is stretched can see from Fig. 1 and Fig. 2, it comprises micro machine 2, leading screw and nut mechanism 3d and nut 3d1 thereof go up the right angle frame 4 that connects, right angle frame end in addition is connected with the support 5 of decelerator 3e, and the axis d-d of leading screw and nut mechanism 3d is parallel with the axis e-e of decelerator 3e.All can have the long screw 41 of adjustable rod on two bars of right angle frame.

The mechanism that arm is back and forth rotated in vertical also can see from Fig. 1 and Fig. 2, the worm type of reduction gearing 3c that it includes micro machine 2, is connected with micro machine, the output shaft axis c-c of this decelerator is vertical with the axis d-d of leading screw and nut mechanism, and fixed a connecting rod 8 with the housing Joint of leading screw and nut mechanism 3d on its output shaft.Connecting rod 8 can also see from Fig. 5, it with the worm gear output shaft between be connected with key so that it moves with worm gear, its end in addition is integrally welded with the housing of leading screw and nut mechanism, represents the position of its welding among Fig. 2 and Fig. 5 respectively with symbol III.

Above-mentioned mechanism all is installed on the bearing 7 of a band connector 1, and this connector can same easily seat affixed (seat is represented in the drawings), takes exercise to make things convenient for user to be sitting on the seat.

This utility model rehabilitation device also can make the housing of worm type of reduction gearing 3c same by micro machine 2 drive and the output shaft axle head of the worm type of reduction gearing 3b of the axis d-d coaxial line of its output shaft b-b and leading screw and nut mechanism affixed, represent that with spot welding I it is affixed among Fig. 5 and Fig. 2.

This utility model rehabilitation device can represent that with symbol II it is affixed with the output shaft of the vertical worm type of reduction gearing 3a of axis d-d of leading screw and nut mechanism respectively by affixed another its output shaft axis a-a in Fig. 2 and Fig. 5 on the housing of worm type of reduction gearing 3b.

The circuit of this utility model rehabilitation device can be seen from Fig. 6, during in energized and from keyboard input signal, little processing block CPU promptly shows the program of its operation and drives micro machine (representing micro machine with M among Fig. 6), work to micro machine simultaneously detects, mechanism that is connected with micro machine or decelerator promptly carry out work, drive upper limb and do corresponding motion.

The working condition of this utility model paralytic upper limb function recovery device is as follows: energized and when pressing some keys (power supply and keyboard do not give expression among the figure), then can start connected micro machine immediately, and carry out work by the coupled mechanism of this micro motor for driving, when wherein decelerator 3e back and forth rotated, it was the axis swing with e-e that the carriage on it drives forearm; Decelerator 3c can drive arm and swing in the vertical at arm place along the c-c axle; Decelerator 3a can drive arm and swing in the horizontal plane of self; Decelerator 3b can make arm and shoulder joint do back and forth twisting by the housing of all-in-one-piece decelerator 3c solid with it, 3d; During the moving right of leading screw and nut mechanism 3d, at first activity box 92 is moved to right by cable wire, asking this moment hands cloth 97 promptly to form triangle nest N (representing to hold in the palm hands cloth a certain position at the volley with double dot dash line among Fig. 4) and this nest N on the position touched of finger constantly forces and points crinkle bending to the right, when activity box arrives the framework right-hand member, wrist also is forced to bending, and elastic force cloth is stretched in this process.Continue to the right as leading screw and nut mechanism 3d, then can make the elbow joint bending, therefore finger, wrist all obtain the passive exercise of first order buckling; When leading screw and nut mechanism is moved to the left, then dragging elbow joint by carriage 6 trails, and when elbow joint all trails, carriage, framework stop motion and activity box is got back to its home position under the effect of elastic force cloth contractility, finger, the whole spread aparts of wrist this moment.

The utility model has the advantages that: it is simple in structure, effect can 1) to make the mechanism of the bent exhibition of finger, wrist Lean on, and it is with flexibility, can injure finger, wrist; 2) the utility model device for rehabilitation can make upper limbs All joint, muscle, channels and collaterals carry out passive exercise, so rehabilitation efficacy is good; 3) the utility model rehabilitation Device is finished passive exercise by keyboard operation, and it is easy to use, safe and reliable, and can forge according to paralysed limb The needs of refining are selected the motion of mechanism, so that the exercise of certain part is strengthened or reduces.
