Fluid containing covers - with electrical circuits

Claim 1

A cover to be placed on the human body over and around a surface wound thereon to hold healing fluid in contact with the wound, the cover being made of silicone rubber and having; a thin, flexible ring having means to hold the ring on the skin of the body adjacent a wound thereon; a hollow chamber formed by a thin, flexible wall connected to said ring and extending away from the ring so as to be spaced away from a wound when the ring is held on said skin; first means on said wall to receive and permit a hypodermic needle to extend into the inside of said chamber by piercing the first means, the needle being for use in filling the chamber with fluid and the first means, when the needle is removed, closing off the pierced first means to prevent fluid from leaking therethrough. second means on said wall to receive and permit a hypodermic needle to extend into the inside of said chamber by piercing the second means; the needle being for use in venting air out of the chamber when the chamber is receiving healing fluid from a hypodermic needle in said first means and the second means, when the needle is removed closing off the pierced second means to prevent fluid from leaking therethrough; and a thermoelectric stack made up of successive pairs of dissimilar metal discs interspersed with non metallic resistive discs to partially insulate each pair of metallic discs and establish the total series resistance of the stack, an anode rivet having a stem, an insulation cylinder surrounding the stem, the stack being assembled on said insulation cylinder surrounding the stem such stem penetrating said chamber, the thermoelectric stack including a first compressive washer on said chamber a negative skin electrode having a ring on the outside surface of said hollow chamber engaging said first washer, a second metal washer, the stack being connected to a top of said stem via a riveting operation to said second washer, which also provides compression to produce a seal for the stack to the chamber and good contact between all dissimilar metal discs, to establish an electrical circuit path which includes said negative skin electrode ring, the thermoelectric pairs of discs, the resistive discs, said anode rivet, the fluid in the chamber, and the body; with all in series to sustain a steady ion flow through the fluid and the wound that is in contact with the fluid in the chamber.
