The specification discloses a sterile system and associated method for dressing vascular access sites in the skin penetrated by needles or catheters. The system includes a sealed container defining a sterile enclosure within which are provided dressing components including a sterile absorbent pad for being adhesively secured over the vascular access site to cover and protect the penetration area and the lead-in portion of the catheter tube, and a sterile adhesive strip for being adhesively secured to the skin of the patient under the tube as it emerges from beneath the pad, and between the skin and the pad along the edges of the pad in opposite directions from the tube exit location. The dressing components cooperate to engage the tube against lateral and longitudinal movement to provide a more secure infusion site. The system as a whole provides a more sterile, reliable and uniform dressing for vascular access sites.
A system for dressing a tubular access site adjacent the skin of a patient penetrated by an invasive medical device such as a catheter tube, said system comprising: a container defining a sterile, sealed enclosure therein; and a preformed, sterilized dressing located within said enclosure, said dres
A system for dressing a tubular access site adjacent the skin of a patient penetrated by an invasive medical device such as a catheter tube, said system comprising: a container defining a sterile, sealed enclosure therein; and a preformed, sterilized dressing located within said enclosure, said dressing comprising: a first sterile dressing component comprising an absorbent pad dimensioned to substantially cover the access site and adapted to absorb fluid from adjacent the access site, said absorbent pad having a first surface for being disposed adjacent the site and a second surface for being disposed facing away from the site, a breathable adhesive-backed web disposed adjacent said second surface of said pad and extending out from a marginal edge of said pad for adhesively securing said pad to the skin around the access site, a barrier film disposed adjacent said second surface of said pad intermediate said pad and said web and adapted to limit entry of moisture and bacteria into said pad from the environment while providing a controlled rate of evaporation of fluids from said pad, a substantially non-adherent covering disposed adjacent said first surface of pad to be placed against the skin to limit adherence of said pad to skin tissue or exudate adjacent the site, and a peel-away cover layer covering at least the portion of said adhesive surface of said web extending out from said pad to provide ready exposure of said adhesive surface of said web by peeling said cover away for attachment of said first dressing component to the skin about the access site, wherein when said first component may be placed over the access site such that a portion of said web will overlay the catheter tube and thereby define a catheter exit location at which the catheter tube is engaged between said web and the skin; and a second sterile dressing component comprising a breathable web having an adhesive surface and a peel-away cover covering said adhesive surface of said web to provide ready exposure of said adhesive surface by peeling said cover away for attachment of said web of said second sterile dressing component to a desired surface, said web of said second dressing component being dimensioned to provide adhesive securement of a first portion of said web to the skin of the user beneath the catheter tube adjacent the catheter exit location and extending out along opposite directions from the exit location, and to provide adhesive securement of a second portion of said web of said second component to said web of the first dressing component along the marginal edge of said web of said first dressing component adjacent the exit location, wherein the catheter tube may be engaged between said web of said first dressing component and said web of said second dressing component so that undesired lateral and longitudinal movement of the tube may be restricted.
