Description

The upper limb therapeutic instrument

This utility model relates to a kind of rehabilitation appliances that paralytic or other patient's upper limb elbow joint, shoulder joint function are taken exercise.

Help the movable extremities joint of paralytic, muscle; accelerate limb functional recover, prevent the rehabilitation appliances of ankylosis; as bedside limbs joint locomotorium; it is to make patient's upper limb and lower limb all carry out active big apparatus simultaneously; because movable upper and lower extremities simultaneously, regular meeting influences other treatment in early days, needs the strict exercise opportunity selected; volume is big in addition, and certain limitation is arranged in the use.There is a kind of passive type to temper wheelchair, can be used for upper and lower extremities takes exercise and back massage, its drive system is by two cover motor, deceleration, actuating device constitute, the deficiencies in the prior art part mainly is: 1, be unsuitable for early treatment, recovery, wheelchair need treat patient's state of an illness steadily, can stand or sitting after can use, miss an opportunity because of a delay, it uses and has limitation equally; And the recovery of this class patient upper extremity function is more difficult than lower limb, does not also have the early stage upper limb type apparatus that uses of a kind of suitable patient; 2, big, the complex structure of volume, the cost height.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of simple structure, cost low, is fit to the early stage upper limb therapeutic instrument product that uses of patient.

Can take following technical scheme to realize purpose.The upper limb therapeutic instrument, comprise motor, deceleration, actuating device part, but it also has the upper limb carriage, actuating device is made of crank, connecting rod and rocking bar, and carriage is installed on the rocking bar, and rocking bar lower end and support are hinged, crank is installed on the reduction unit output shaft, and an end of suitable bar is connected with rocking bar with crank, other end.

Under the prerequisite that satisfies the said structure requirement, specific constructive form, size as for the integral body of upper limb therapeutic instrument, each funtion part, each zero member, connection between member, fixed form, position relation etc., all can be according to using needs, take the circumstances into consideration to set, they can both realize purpose, guarantee the serviceability and the effect of this upper limb therapeutic instrument.

The relative prior art of the technical program has following advantage and effect:

Be the upper limb type apparatus that a kind of suitable patient treats in early days and later on, recovers, be beneficial to the recovery that makes hay while the sun shines, helps positively patient's upper extremity function, blood circulation promoting; The scope of application is wide, is not only applicable to hemiplegic patient, also can be used for upper limb elbow joint, the exercise of shoulder joint postoperative function, both can make shoulder joint make circular motion, also can make its swing, can be suitable for all kinds of hospitals and family and use; Simple structure, volume are little, cheap, easy to operate, flexible.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of upper limb therapeutic instrument;

Fig. 2,3 is respectively a left side, the vertical view of Fig. 1.

The upper limb therapeutic instrument, except that motor, deceleration device, it also has upper limb carriage 1, actuating device is made of crank, connecting rod 3 and rocking bar 2, and carriage is installed on the rocking bar, and rocking bar lower end and support are hinged, crank is installed on the reduction unit output shaft, and an end of connecting rod is connected with rocking bar with crank, other end.The conversion on demand of the link position of connecting rod and rocking bar is to change amplitude of fluctuation.Can be provided with fixingly on the carriage, during use patient's upper limb be placed on the carriage and with rope band and carriage and fix, press power button and get final product work with rope band and so on.

Among the therapeutic instrument of upper limb shown in the accompanying drawing embodiment, its drive system is to be installed on the unidirectional variable-speed motor axle 5 of gear reduction with disk 4, an end of connecting rod and disk, the structure that other holds and rocking bar connects and composes.Disk rotates a circle, and the upper and lower swing of rocking bar belt bracket is once adjusted the knob on the panel, makes the unidirectional variable-speed motor of YTCJ-90-4/100 gear reduction be controlled at 14～60 rev/mins, is advisable between 45 °～90 ° of the rocking bar range of activity.Can adjust rotating speed and amplitude of fluctuation at any time on demand, changing rotating speed is the frequency of conversion swing.

The electromagnetic pulse device is set in the therapeutic instrument, when doing mechanical movement, with electromagnetic pulse relevant acupuncture point is stimulated, then treatment, recovery effects are more obvious.

The serviceability of accompanying drawing illustrated embodiment, result of use are good.
