Abstract: A trans-dermal medication application cell for temporary attachment to the skin of a patient to facilitate the diffusion of medication solution from the cell's interior to the skin of a patient where it will be absorbed. A housing non-reactive with medication solutions is closed by a micro-porous diaphragm or membrane. A formed perforated medical foam sheet is secured to the housing and, in use, to the skin of a patient by a medical adhesive. A release sheet and vapor barrier secured to the foam sheet block exterior access to the micro-porous membrane and adhesive coated foam sheet prior to application to the patient's skin. A self locking and sealing plug closes the filling aperture in the housing in the principal invention embodiment.

Abstract: A medication application system comprising a container for medication adhesively secured to the unbroken skin of a patient. The container is cup-shaped and closed on its open side by a micro-porous diaphragm or membrane through which the medication passes from the container to the skin surface where it is absorbed. Particular means are described for adhering the container to the skin and for sealing the container prior to its use. Various pharmaceutically effective medications in differing concentrations found to be effectively dispensed from the container, are described.

Abstract: A blind riveting and sealing system for sealing circular openings in sheet type materials and for securing together plural sheets. Each of the sheets to be secured together has an identical size hole for accommodating the rivet of the invention in a force fit relationship. Additionally, one of the sheets has a reduced diameter step in the rivet receiving hole to form a resilient annular locking flange. The rivet of the invention has a necked down portion to form a beveled seat face. This beveled seat face engages the resilient annular locking flange to lock the rivet in position and seal the circular openings in the sheets.

Abstract: A biomedical electrode for use with a signal receiving apparatus is disclosed herein. The electrode includes an open-sided resilient container having a permeable diaphragm closing the open side. A terminal plug is positioned in connection with the resilient container. An electrolyte is contained in the container, and permeates the permeable diaphragm. A flat closed-cell perforated flexible annular mounting pad surrounds the container, and is secured to it. A flexible stainless steel ring engages the resilient container, and secures the flat closed-cell perforated flexible annular mounting pad in fixed engagement with a flange of the container. A uniform adhesive is secured to a side of the flat closed-cell perforated flexible annular mounting pad adjacent the permeable diaphragm for adhesively securing the electrode to the surface of a subject. The resilient container and flat closed-cell perforated flexible annular mounting pad are releasably mounted on a release paper and diaphragm sealer.

Abstract: The subject matter herein is an electrical connector particularly adapted for quickly and easily electrically and mechanically connecting insulated ends of a pair of insulated electrical wires. The subject connector includes an elongated penetrator tube, having a flared annular lip at one end. A groove is formed in the tube to provide a convenient means for holding the tube in an automatic assembly machine. The tube has a plurality of penetrator locks formed integral with side walls of the tube. Each of the locks has a plurality of penetrator prongs extending inwardly of the tube. One of the penetrator prongs in each of the locks is longer than the remainder of the prongs to provide a holding prong, which engages the insulating material as the wires are inserted into the tube to hold the wires in the tube prior to final locking. Each holding prong has a rounded side adjacent to the flared annular lip to facilitate insertion of insulated wires and avoid tearing of insulation and stubbing of the wires.

Abstract: A biomedical electrode for use in cooperation with a signal-receiving apparatus is the subject matter of this invention. The electrode includes an open-sided resilient transparent container, with a microporous diaphragm closing the open side. The container includes a filling aperture on the side opposite the open side. The container has three resilient fingers formed integral therewith, which fingers contact the diaphragm to hold the diaphragm outward from the container. The resilient fingers are equiangularly spaced about the filling aperture. An annular sealing flange is formed integral with the container; and extends into the filling aperture. A terminal plug is positioned in the filling aperture, in seaing engagement with the annular sealing flange, to seal closed the filling aperture. The terminal plug includes a cup, which is deformed slightly during insertion of the terminal plug into the filling aperture.
