The programmable device with an amplifier is connected.

In FIG. 1 - the proposed apparatus, General view / in FIG. 2 ~ structural diagram of the apparatus.

The apparatus contains a base 1, limb attachment elements made in the form of rings 2, pivotally mounted at the ends of the rods 3, and interchangeable bracelets 4 or supports (not shown) installed in the rings 2 with the possibility of rotation, an electric drive with a gearbox 5 and drive motors 6, two pairs of rods 3 and 7, pivotally interconnected, servo systems, including sensors 8 of the angular 'positions of the rods. 3 and 7 and differential amplifiers 9, connected to the drive motors 6, on the base 1 there is a folding chair-couch 10, w tangs 3 and 7 are equipped with adjustable load elements with electromagnetic clutches (not shown), a recording device (not shown) with a program carrier 11 is electrically connected to the sensor 8 of the angular positions of the rods 3 and 7, and a program reproducing device 12 with an amplifier is connected to the input of the drive motors 6 9.

The apparatus for the development of doors in the joints of the limbs works as follows.

To record the program of movements, the doctor or trainer sits down (lays down, becomes) in the couch chair 10, he is paired with limbs (for example, hands) in bracelets 4 or footsteps, the program recorder is turned on and the doctor begins to make the necessary movements for training the patient (for example, supination or pronation movements). The movements of supination (or pronation) with a bracelet 4, rigidly fixed in the rotary rings 2, are transmitted along the kinematic chain to the angular position sensors 8, the outputs of which are connected to the recording device. The program is recorded on the carrier 11 (the angular position of the sensors in time), after which the patient sits down (lies down, becomes) on the chair 10. On the paired limbs of the patient who need development (for example, hands), put on bracelets 4, rigidly connected to the rotary rings 2. Electromagnetic couplings of both their limbs are engaged, coupling the drive motors 6. Each of the sensors 8 is connected to the input of the amplifier 9, on the other the input of which is connected to the output of the recording device, and the output of the amplifier is connected to that electric motor 6, which is mechanically connected to the sensor 8 of the angular position, the output of which 10 is connected to the input of the amplifier 9, after four programmovosproizvodyaschee switched on device 12. The input of the amplifying element enters a difference signal between the outputs programmoza15 authorizing devices and signals coming from respective sensors 8 angular position. The drive motors 6 begin to rotate the respective sensors 8 until

2Q until the difference signal at the input of amplifiers 9 becomes zero. At the same time, bracelets 4 with limbs fixed in them (for example, hands) forcefully perform supination (or pronation) movements according to the recorded program. The speed at which the patient’s limbs make movements can be changed at the discretion of the doctor (or trainer) by changing ₃₀ the playback speed of the recorded program, while recording and playback on each pair of rods 3 and 7 can be performed autonomously, so one paired limb can make movements different from the other.

Claims (1)

The invention relates to medical technology, namely to orthopedics and traumatology. A known apparatus for developing movements in the joints of the extremities, comprising a base, elements of the splicing of the extremities, an electric drive with a reducer and driving motors, two pairs of rods pivotally interconnected, tracking systems including sensors of angular positions of the rods and difference amplifiers connected with driven electric motors.
