(54) MULTICHANNEL MYO-ELECTRIC STIMULATOR

1 v ;. The invention relates to medical technology, namely to devices for the rehabilitation of patients with injuries and abnormalities of the musculoskeletal system in the postoperative period.

According to the main author. St. THE USSR . No. 914069 A multichannel microelectrostimulator contains a master pulse generator with a following frequency regulator, a pulse distributor, a switching frequency setter, a filling signal generator, p & .

- However, the famous multichannel mibelectrostimulator. It works in the echoactive mode, i.e. by imposing a hard-to-heat regimen of muscle contractions irrespective of the patient’s general condition, which prolongs the recovery time of the muscles.

The purpose of the invention is to reduce the time it takes to restore the health of the children by providing an interactive p & a stimulation and forming conditioned reflective connections.

The goal is achieved by the fact that the multichannel myoelectrostimulator according to ed. St. No. 914069, an angle-code converter, the input of which is mechanically connected to the axis of the load mechanism, 10 rotatably mounted, and a multi-channel pulse distributor, connected to the angle-code converter and the filling signal parameter controllers, are entered. In this case, the angle-code converter was implemented in the form of a series-connected tachogenerator, a pulse shaper, and a direct and inverse selection circuit of the output code.

The drawing shows a structural diagram of a multichannel microelectroelectric amplifier. A multichannel microelectrostimulator contains a master pulse generator with a frequency control trace. vanes, pulse distributor, switching frequency setter (not shown), filling signal generators 1, adjusting 2 parameters of filling signals, current regulator 3, contact device 4, amplitude modulator 5, amplifier b, angle-code converter, input which is mechanically connected with the axis of the load mechanism 7 fixed for rotation, and a multichannel distributor 8 pulses connected between an angle-code converter and regulators 2 parameters of filling signals, while the angle-to-converter This device is made in the form of a series-connected tacho generator 9, a pulse shaper 10 and a direct q inverse unitary code allocation circuit 11, and the patient's terminal is fixed in fixation elements 12. The device works as follows. A patient, of which one of the limbs is fixed in the elements of the 12 fi saTsia, sets in motion mechanism 7. loads, which are mechanically connected by an axis with a tachogenerator 9, generating a signal that is proportional to the speed or frequency of rotation. This signal is sent to the shaper of U pulses, the pulses of which are fed to the circuit 11 for selecting the direct and inverse unitary codes, i.e. There are single signals corresponding to the direct and reverse phases of the device operation. The signal from the output of circuit 11 is fed to the input of the multichannel distributor of 8 pulses. These square pulses control the 2 parameters of the signals of the fill signals, the generators 1 of the fill signals and the modulators 5 of the fill. Using the current regulator 3, the amplifier 6 sets the optimum current for the patient, which in the form of frequency and amplitude modulated pulses goes through the contact device 4 to certain groups of the patient's muscles. The patient performs the movement specified by him, which leads to the movement of the elements of the device, which causes the appearance of stimulating impulses, and a positive feedback is formed; a larger patient movement leads to a higher level of the stimulating signal, and a decrease in the speed of movement reduces the level of stimulating air. In the case when the patient, due to ignorance of the objective possibilities of his muscular apparatus, stops activating the correspondingly. The muscle group, the device retains the activated state for some time, and then automatically goes on to stimulate the antagonist muscles, which leads to the establishment of conditioned reflex connections, ensuring that the spontaneous patient-defined growth gradually increases. Movement parameters, which provide interactive mode of stimulation. The proposed multi-channel myoelectric stimulator provides an interactive mode of stimulation, which contributes to the formation of conditioned reflex connections overcoming the external negative connections of the same conditioned reflex level formed against the background of injury, illness or psycho-physiological decompensation. Moreover, the basic parameters of the stimulating effect are determined by the actions. and codToarifaeM patient without the participation of the medical operator.
