Abstract

322,679. Dworzan, M. Jan. 18, 1929. Anthropometrical appliances; medicines, administering; measuring conductivity of contents of body cavities. -An apparatus for examining cavities in the body comprises two electrodes at the end of a thin flexible sheath, the electrodes either being of different metals, e.g. platinum and zinc, in order that the current generated by the electrodes in contact with the contents of the cavity may be measured, or they are of the same material, in which case an external source of current is provided, and the conductivity of the contents is measured. Chemicals may be introduced into the cavity and decomposed there by the current from the external source. The sheath may be designed for introduction into the stomach or through the urethra and ureters to the kidneys. In one arrangement, the electrodes, of different metals, are in series with a measuring instrument, a resistance of about 10000-20000 ohms and a switch. In the arangement shown in Fig. 3, the measuring instrument g, which may be of the recording type is in a shunt circuit, and an external source of current i is provided. Resistances m, n are provided to regulate the instrument reading. The electrodes c, d may be enclosed in an outer sheath having openings adjacent to the electrodes for admission of the liquid contents of the cavity. To exclude liquid from the insulation, the electrodes may project slightly from a celluloid cap at the end of the sheath, the cap being filled with paraffin wax. If it is desired to decompose chemicals in the cavity, they are placed in the end of the outer sheath around the electrodes. and the products pass out through the openings in the sheath and mix with the liquid contents of the cavity. In this case, a measuring instrument is not essential.
