WITH

This invention relates to a medical medicine. In particular, to devices for physiotherapy.

It is known a device for measuring idiopathology, which makes it possible to measure the amount of sweat produced, but it cannot be used, and the moment of intense division of cells.

The closest to the proposed sensor is a sweating sensor, containing a dielectric opus, in which the DZ devices are connected to the measuring electrode of the electrode, between which is EELKCi.

A disadvantage of the known ow sensor is that the electrodes in it are placed in something else;.; space, which tells bye on the functioning of flows

In the proposed sensor, the electrodes are made of the same type of plates made of gr - fittized fabric, the body is made as a flat substrate, and on the working side, the electrodes are covered with insulating spacers that repeat the cross section of the electrodes. In this case, the measuring instrument can be made according to the comparator scheme based on the operating instructions.

The device (Fig 2) consists of resistance sensors RX connected to the sockets 6 of the measuring unit 7. I.P.Ptlr Y.

In measurement mode, sterile; ; An RX sensor from the RX was pushed onto the skin at any point with a pair of tweezers and attached to the PDP, the connector 4 of connector 4 is connected to the gn / dam C of the measuring unit V of the measuring unit V. Threshold, b j. The iHHs are controlled by a resistor 8. In ka4 (: p.1 in the threshold element viirzg operational amplifier 9 with high input resistance: h, for example K 284 UD1A, switched on by the comparator circuit.

As soon as the physical properties of this resistance electrolyte appear between the electrodes of the resistance sensor, the resistance of one of the inputs of the operational amplifier 9 changes, which leads to the appearance of a current in the circuit of the indicator 10, for example, a LED. Thus, the instrument signals the onset of the post-perspiration permeability of the skin.

The device allows you to determine individually for ;: each patient, the onset of postperspiration permeability of the skin, which makes it possible to determine the start of physiotherapy procedures, to reduce drugs in a timely manner to the patient's organism, to significantly reduce the consumption of drugs compared to traditional methods of physiotherapy. After the procedure, the used electrode is disconnected from the instruments and discarded.

The resistance sensor is made of cheap materials: electrodes are made of graphitized fabric; substrate and insulating gaskets of any insulating film materials, for example polyethylene.

A detachable connection, for example, of the type of a dressing button in this case, holds a continuous insulating gasket with the electrode, and that; Quickly connect; with feeders. Coverage of labor with opposite CIO ;; OH; J

The use of an operational amplifier for the manufacture of a measuring unit of the device allows, in addition to obtaining small dimensions, to provide electrical bezogu.-varnosti in the work, because small

As a device for lifting

Tempered skin chelazozka up to the moment of psychosection, you can use a heat-air shower type DTV (TU-16-539-975-7E), which is portable (fits in a suitcase) and provides comfortable conditions when the temperature rises, ensures electrical safety.
