(54) УСТРОЙСТВО ДЛЯ ОБУЧЕНИЯ ИНВАЛИДОВ -ДВИГАТЕЛЬНЫМ НАВЫКАМ(54) DEVICE FOR TEACHING DISABLED MOTOR SKILLS

Изобретение относитс к медицинской технике, в частности, к нротезированию.This invention relates to a medical technique, in particular, to nursery.

Известно устройство дл .обучени инвсшидов двигательным навыкам, включающее блок питани и соединенные между собой щуп и щит с проволочныг/ш дорюжками ij. A device for teaching motor skills is known, including a power unit and interconnected probe and shield with wire / i pads ij.

Однако процесс обучени инвалидов двигательным навыкам на известном устройстве продолжительный, а спектр движений, которые возможно освоить на нем, ограниченный.However, the process of teaching disabled motor skills on a known device is long, and the range of movements that it is possible to master on it is limited.

Цель изобретени - сокращение врел1ени на обучение Поставленна цель достигаетс тем/ что в устройстве дл обучени инвалидов двигательным навыкам, включающее блок питани и соединенные между собой щуп и шит с проволочными дорожками, введены соединенные между .собой формирователь импульсов, вход которого соединен со щупом, и счетчик , датчик времени схвата и комму- . татор, а также индикатор времени, вход которого подключен к выходу коммутатора, датчик силы схвата, первый выход которого соединен со счетчиком , а Етороп подключен к второму входу коммутатора, и генератор секунд.The purpose of the invention is to reduce the training allowance. The goal is achieved by the fact that in the device for teaching disabled people motor skills, including a power supply unit and interconnected probe and sews with wire lanes, a pulse shaper connected between itself and an input probe are inserted between counter, time sensor gripper and comm. A tator, as well as a time indicator, the input of which is connected to the switch output, a gripper force sensor, the first output of which is connected to the meter, and Etorop is connected to the second input of the switch, and a generator of seconds.

при этом третий вход коммутатора подключен к второму выходу формировател импульсов, четвертый вход - к щиту , а п тый - к выходу генератора секунд .the third input of the switch is connected to the second output of the pulse generator, the fourth input to the switchboard, and the fifth to the output of the generator seconds.

На чертеже изображена блок-схема устройства дл обучени инвалидов двигательным навыкам.The drawing shows a block diagram of a device for teaching disabled motor skills.

Устройство содержит щуп 1, ПОДКЛР ченный к формирователю 2 импульсов, выходы которого соединены с блоком 3 коммутации и со счетчиком 4, датчик 5 силы схвата, соединенный со счетчиком 4, датчик 6 времени схвати., индикатор 7 времени, генератЬр 8 секунд , щит 9 с проволочными дорожками заданной формы, блок 10 питани . Кажда проволочна дорожка щита 9 The device contains a probe 1, CONNECTED to the pulse shaper 2, the outputs of which are connected to the switching unit 3 and to the counter 4, the gripper force sensor 5 connected to the counter 4, the gripper sensor 6, the time indicator 7, generator 8 seconds, shield 9 with wire tracks of a given shape, power supply unit 10. Each shield wire 9

20 имеет начальную и конечную точку в виде контактов, соединенных соответственно через блок 3 коммутации с цеп ми индикатора 7 времени. Датчик 5 силы схвата представл ет собой рычажный переключатель , контакты которого соединены со счетчиком 4, а через блок 3 коммутации - с индикатором 7 времени.20 has a start and end point in the form of contacts connected respectively via a switching unit 3 to the time indicator lines 7. The gripper force sensor 5 is a lever switch, the contacts of which are connected to the counter 4, and through the switching unit 3 - to the indicator 7 of time.

Claims

The device works as follows. For the study of motor coordination, the counter 4 is connected to the power supply circuit. With the aid of the probe 1, the learning invalid performs successively spatial movements along the configuration of the wire paths of the shield 9, starting movement from the starting point. In this case, the probe 1 should not touch the boundaries of the tracks. The signal from the starting point of the first wire track is transmitted through the switching unit 3 and turns on the start circuit of the Time Indicator 7, which is started by the generator for 8 seconds. Each time the probe touches the boundaries of the wire, the touch signal is transmitted to the driver 2, from which the pulse is transmitted to the counter 4, which accumulates error information when the movement is performed. When the probe touches the end point of the wire track, the time counting by the indicator stops. When learning how to control the force of the fingers with an artificial brush, the sensor 5 grips the power circuit is turned on. Counter 4 and indicator 7 in meni are set to the zero position. The fingers of the prosthesis ingvshid compresses the levers of the gripper force sensor 5 which move along the switch contacts and the signals from each of the contacts go to the counter 4, which is set to a position with a corresponding force applied to the gripper force lever. Simultaneously with the start of movement of the lever of sensor 5 to the start circuit of indicator 7, time through the switching unit 3, the signal from the first contact of the lever switch of sensor 5 stops. The counting continues until the moving lever of sensor 5 is set to a certain position, resulting in stopping the indicator 7. Thus, in the process of learning, the time is determined during which the gripping force is reached during the control of the prosthesis. In the study of the time of gripping or opening the brush is first performed - the reset of the counter 4 and the indicator 7 of time. The fingers of the learner's prosthesis are mounted on the levers of the grab time sensor 6. With the beginning of the movement of the gripper or opening through the switching unit 3, the time indicator 7 enters the circuit, which receives pulses from the generator for 8 seconds. At the end of the movement, the indicator 7 is turned on and the time for performing the gripper or opening it with the fingers of an artificial brush is determined. Thus, the proposed device allows speeding up the process of teaching disabled motor skills due to the automatic instrumental self-time of time and quality of performing coordinated movements with the prosthesis, to master a wider range of movements that can be produced by the prosthesis. The device allows you to determine the number of errors in the execution of specified movements, determine the time of execution of one or another movement, the gripping force of the fingers of an artificial hand and the time during which this force is achieved, the time of full gripping or opening the fingers of an artificial hand. The invention is a device for training disabled motor skills, including a power unit and interconnected probe and shield with wire lanes, characterized in that, in order to reduce training time, interconnected pulse generator, the input of which is connected to probe, and a counter, a gripper time sensor and a switch, as well as a time indicator whose input is connected to the switch output, a gripper force sensor whose first output is connected to a meter, and the second is connected to the second ode switch and generator seconds, the third input switch connected to the second output of the pulse shaper, the fourth input - to the panel, and a fifth generator output -.k seconds.
