SU375061A1 - DEVICE FOR STUDYING STATIC FUNCTIONS - Google Patents

Description

one

The invention is related to devices for studying systems of the human body, in particular its aporno-motor system, by analyzing cooTBeTCfByroniHx reactions to external disturbances.

The known devices for studying static functions of a person under the action of shocks, ne (rpendiculum, longitudinal OS. Body and containing a lever and a sensitive element) do not provide impulses of a given intensity, which does not allow to process and compare the results obtained.

The proposed device, in which the indicated 1dostato, is eliminated, differs from those known in that it is equipped with a stand and a movable bracket, a unit, a cable, a p, alternating, retractable DC electromagnet, a clamp, a sensor, and the cable thrown over the block located on K | ron1shtezh is not, the two ends are connected to the electromagnet, and the other to the belt fixed on the body of the test person and not drying the clamp with sensor IB Aide, nanrymer, strain gage.

FIG. 1 shows the proposed device, side view and OBepixy; in fig. 2 - collar with sensor, cross section.

The device contains an electromagnet 1, said | replenny on. Massive wellness 2,

Measles 3 of which are connected by a cable 4, thrown over the block 5, to the clamp 6, located on the belt 7. The block 5 is fixed on the movable bracket 8 with the fixing bolt I allowing the height to be changed depending on the height of the studied . In the clutch 10 moving along the belt 7, there is a sensor 11, which is an elastic metal plate with a strain gauge glued on it. The winding 12 of the electrical 1PNIT is connected to the output of the pulse generator. j

| Device | In | | works as follows.

The belt 7 is put on the test piece, and the sensor is located on the conventional line of action of the push; The impulse generator sets the required amplitude parameters of the pulses that are applied to the winding 12 of the electromagnet. Under the influence of a magnetic field, the bark 3 is drawn in, and with a predetermined force the push is transmitted, transmitted through the troik 4 'and the belt 7 of the subject. The tensioned belt forms a metal plate of the sensor, and the strain gauge pasted on it converts the mechanical deformation into an electrical signal, which after amplification is recorded on the recorder simultaneously with the recording corresponding to the response to the impulse.

Subject matter

V1StroySTVO to study the static functions of a person when exposed to tyulchk, perpendicular to the longitudinal UN body, contains a lever and a sensitive element, characterized in that, with a slit of getting impulses of a given intensity, there is a base with a stable

a bracket, a block, a cable, a belt, a retractable Electrama.gn.it constant taka, a buckle and a sensor, and a cable thrown over the block placed on the bracket is connected to the electromagnet at one end and to the other end of the belt -True and carrying a collar with sensors in (Vid, nugrimer, tenzorez.istor.
