DEVICE FOR MEASURING DIFFERENCES IN CONDUCTIVITY

Abstract

A device for measuring differences in conductivity that allows early detection of infectious/inflammatory periodental and/or apical diseases or in joint and/or muscle regions, before they can even be detected radiologically. The device has an electrical emitter in millivolts, with a given negative-peak square wave and a given frequency, both defined by a pulse width and interval between pulses, which, by means of two electrodes, one stationary and one movable, is able to produce a mild tingling sensation on the patient's skin immediately over the teeth apices or joint and/or muscle regions as well as dermatological, glandular and integumentary areas affected by inflammation and/or infection and display the intensity of the condition affecting the tissue to the professional on an illuminated scale display.

[0070] It indicates a connection for movable electrode (3) and next to it, a connection for a multipurpose movable electrode (13), both connections being configured with the same colour.

[0071] Below these connectors, a connector for a stationary electrode (2) is shown, configured with a different colour to avoid connection errors, and an activation indicator light (18) is also shown.

[0072] Application of the stationary electrode (2) is always carried out on the patient's skin, on an area without hair or that is shaved to obtain perfect contact with the bare skin as it is attached by means of a disposable adhesive patch.

[0073] The movable electrode (3) with blunt tip, interchangeable and sterilizable, is applied to the skin of the face that is clean and without cream; it is applied to the skin surface, without exerting excessive pressure, on each portion of the corresponding skin over the teeth apices to be examined.

[0074] The multipurpose movable electrode (13) has the same application and includes the illuminated scale in the electrode holder itself so that the quantification of biological response can be viewed on the device and on the electrode at the same time.
