ABSTRACT:
An improved portable battery powered therapy applicator which applies a high frequency electromagnetic field to a living tissue for promoting hematogenous effects. The applicator is in use to be attached to the skin of a patient and has a casing encapsulating therein, in addition to the battery, an antenna for directing the high electromagnetic field and electronic components forming an oscillator which energizes the antenna. These parts are mounted on a substrate which is made of a rigid material sufficient to resist deflection or deformation in order to protect the antenna on the substrate from deforming or receiving considerable stress at the time of detaching the applicator from the skin. Thus, the antenna can be kept free from breaking even through repeated operations of detaching the applicator, greatly enhancing reliability and prolong an operation life of the applicator.
