SU707571A1 - Apparatus for testing differential response of kinesthetic analyzer - Google Patents

Description

The invention relates to medical equipment and can be used in works on the physiology and psychology of work, as well as in related fields.

A device for studying the differential sensitivity of a kinesthetic analyzer is known: having a loading element, a plastic bag is used as a load element, which is bed-filled with water from a Mariotte vessel with a 100 ml graduated glass burette. The burette is connected via a tee with rubber tubes to both a vessel containing iodine 15 and a plastic bag. The subject sits blindfolded and holds the bag with a small rubber bulb fl] attached to it.] · 20

However, this device does not ensure the purity of the experimental conditions, since there is no certainty that the subject in assessing changes in weight will not be guided by indirect -25 signs (noise entering the bag \ water, etc.). Changing the weight of the bag is possible only in the direction of its increase, which creates the corresponding attitude (expectation) of the subjects, influ-

The aim of the invention is to increase the objectivity of research.

For this, the load element is made in the form of an electromagnetic coupling connecting to each other with a cable fixed to it with a handle, an electric motor and a current regulator in the electromagnetic coil, of the coupling. At the same time, an indicator of the set force value connected to a force regulator is introduced into the device. current. '.

In FIG. 1 shows a device for studying the differential sensitivity of a kinesthetic analyzer, a kinematic diagram; in FIG. 2 - the same general view.

The device for studying the differential sensitivity of the kinesthetic analyzer contains a two-phase electric motor 1 with a gearbox, an electromagnetic clutch 2, mounted on the output shaft of the electric motor using small ball bearings with a cable 3 attached to it with a handle 4. In addition

The experimenter puts stepwise and smooth controls in. position O and turns on the device in the network. On the front panel of the device, the red indicator light of readiness for operation of the device lights up. Smooth. With the regulator, the experimenter slowly builds up what is set by the device by step. effort until three times until the subject notices its appearance. Using the button 7 located on the front panel, the experimenter turns off the applied force (in order to exclude the testee’s fatigue) and registers the indicators of the pointer device. Then, the former force is applied again to the ball and slowly builds up until the subject subjectively marks it “with increases. By varying and increasing the amperage, difference thresholds are determined and recorded at a given initial level of the set force. Reg. The current strength controller allows you to stepwise change every 200 g the amount of force from 0 to 2000 g and smoothly measure. • select differential thresholds for any initial value of the usile specified by the device within the specified limits.

there is a current regulator 5 in the electromagnetic clutch winding and an indicator 6 of the set force value connected to the current regulator 5.

Structurally, the device is designed in the form of a device (Fig. 2), _ inside of which an electric motor ’, an electromagnetic clutch and a current regulator are mounted on a massive metal 'Play'T'ё. Indicator 6 is placed on the front panel. A cable 3 with a handle is located on the side of the device.

'·. When the electric motor rotates, the muff.ha initially slides freely relative to the output shaft, and the test subject, holding the shyrek in his hand, practically does not feel any effort. ! Then, a metered electric current supply is supplied to the coupling. The resulting electromagnetic field creates a clutch between the electromagnetic coupling of the hall - the electric motor, '' as a result of which the moving shaft of the electric motor begins to entrain the electromagnetic coupling. The test subject, holding a cable in his hand, compensates for the resulting electromagnetic force; resulting in a coupling ost ^ '^^''''Ήδ'πό ^ ΒΗΚΗοδ. Stepwise or smoothly changing the force of the electric current supplied to the electromagnetic clutch, one can stepwise or smoothly subsidize the test force being set. The current supplied to the electromagnetic clutch is proportional to the amount of force set by the device, and is measured by an indicator in the form of a pointer device, calibrated in 'grams. ^; ~ '·.
