Electrical therapy apparatus.

摘要

A portable battery powered electrical therapy apparatus for emitting a low power r.f. field to promote wound healing without significant tissue heating, is provided with an improved switch (4) operable once only to switch on the apparatus when it is desired to commence therapy. The apparatus runs continuously until the battery (3) is drained and then the apparatus is disposed of. The electrical circuits, the battery (3) and the switch contacts (8, 9) are mounted in a sealed container (1), and the switch (4) can be operated without breaking the seal of the container, thus preventing fluids from flowing into the container so as to prevent the formation of an unsterile culture within the container during therapy.
