  • Publication number: 20050042240
    Abstract: An antibacterial fluid may be applied to a tubular medical cannula for access to a patient. The fluid comprises a typically metabolizable antibacterial formulation having a viscosity of at least about 5,000 cp. The cannula may then be inserted into the patient with an increased lubricity for a reduction of pain, while at the same time, unlike silicones, preferred materials do not readily accumulate in the patient. The tubular medical cannula may be a rigid, hollow needle, sharp or blunt, a spike, or a flexible catheter. Also, the viscous antibacterial fluid may be used to lock a catheter or other cannula while implanted in the patient, for storage purposes. The formulation is typically an alcohol plus a viscosity increasing agent.

  • Patent number: 4077397
    Abstract: A disposable electrode assembly for establishing electrical contact with an underlying skin surface includes a relatively thin base member having a central hub portion and an adhesive-coated undersurface, a conductive gel-impregnated sponge contact contained in a downwardly facing recess located in the hub, and a relatively thick and inflexible cover member coextensive with the base member. In storage the cover member is attached to the undersurface of the base member by the adhesive and the sponge is confined within the recess. Prior to use the base member is peeled away from the cover member to expose the adhesive surface, which when applied to a skin surface holds the sponge contact in compression-contact therewith. A thumb recess is provided along the margin of the cover member to facilitate removal of the cover member.
