Изобретение относитс  к медицинской технике .The invention relates to medical technology.

Известно устройство дл  онределени  стенени аллергических реакций, содержащее измеритель импеданса и два электрода, один из которых выполнен в виде кольца с перекладиной , а второй представл ет собой подпружиненный стержень, размещенный в центре первого электрода на понеречной перекладине . Однако при работе устройства возможна неточность в измерении.A device for determining the walling of allergic reactions is known, which comprises an impedance meter and two electrodes, one of which is made in the form of a ring with a crossbar, and the second is a spring-loaded rod placed in the center of the first electrode on the transverse crossbar. However, when using the device, inaccuracy in measurement is possible.

Целью .изобретени   вл етс  повышение точности измерени . Дл  этого в предлагаемом устройстве перекладина, выполненна  на оргстекла, имеет продольную щель с делени ми по кра м и расположена в канавке на внутренней стороне кольцевого электрода, а подпружиненный электрод выполнен в виде щупа с шагом сжати  пружины, превышающим изменение рассто ни  между перекладиной кольцеобразного электрода и поверхно-стью кожи.The purpose of the invention is to improve the measurement accuracy. For this, in the proposed device, the crossbar is made on plexiglass, has a longitudinal slit with edges and is located in the groove on the inner side of the ring electrode, and the spring-loaded electrode is designed as a probe with a spring compression step exceeding the change in the distance between the crossbar of the ring-shaped electrode and the surface of the skin.

На чертеже схематически изображено описываемое устройство дл  определени  степени аллергических реакций.The drawing shows schematically the described device for determining the degree of allergic reactions.

Устройство содержит измеритель 1 импеданса , к которому нодключены электроды 2 и 3, один нз которых выполнен в виде кольца 4 с перекладиной 5, а второй представл ет собой подпружиненный стержень 6.The device contains an impedance meter 1, to which electrodes 2 and 3 are connected, one of which is made in the form of a ring 4 with a crossbar 5, and the second is a spring-loaded rod 6.

Кольцевой электрод 2 имеет канавку 7, в которую вставлены закругленные концы поперечной нерекладини 5, благодар  чему нерекладина может поворачиватьс  вокруг центральной оси по окружности кольца 4. Перекладина выполненаиз органического сгекла нли другого прозрачного материала и содержит продольную щель 8 с делени ми по кра м. С помощью зажима 9 к кольцу подключен провод 10 от измерител  импеданса. Электрод 3 выполнен в виде щупа с шагом сжати  пружины 11, превышающим изменение рассто ни  между перекладиной кольцеобразного электрода и поверхностью кожи.The ring electrode 2 has a groove 7, into which the rounded ends of the transverse non-insert 5 are inserted, so that the non-folding can rotate around the central axis around the circumference of the ring 4. The crossbar is made of organic transparent fiber of another transparent material and contains a longitudinal slit 8 divided by edges. using clamp 9 to the ring is connected to the wire 10 from the impedance meter. The electrode 3 is made in the form of a probe with a step of compressing the spring 11, which is greater than the change in the distance between the crossbar of the annular electrode and the surface of the skin.

Устройство примен ют следующим образом. Па зону аллергической реакции кладут электрод 2 так, чтобы центр кольца или нулевое деление на перекладине совпало с точкой ипъекцнн аллергена. В щель 8 вставл ютThe device is applied as follows. Pa the allergic reaction zone put the electrode 2 so that the center of the ring or zero division on the crossbar coincided with the point of allergen potential. In slot 8 is inserted

стержень 6 электрода 3 и, передвига  стержень вдоль щелн и поворачива  перекладину по окружности кольца 4, измер ют и отсчитывают по делению на нерекладине 5 значени  наибольшего и наименьшего размеров видимой зоны покраснени . Далее нажимают на корпус кольца до соприкосновени  его с поверхностью перекладины. При этом пружина 11 сжимаетс  и нередает через шайбу 12 на стержень 6 определенное усилие, величина которого выбрана достаточной дл  обеспечени the rod 6 of the electrode 3 and, moving the rod along the slit and turning the crossbar around the circumference of the ring 4, measure and count the values of the largest and smallest sizes of the visible redness zone by dividing the non-insert 5. Next, press on the ring body until it contacts the crossbar surface. In this case, the spring 11 is compressed and, through the washer 12, is not compressed on the rod 6, a certain force, the magnitude of which is chosen sufficient to ensure
