Abstract
Abstract A transparent, self-adhesive film dressing with a special aerating fenestra, is provided for efficiently securing an percutaneous catheter to the skin of the patient, for continual and complete visual inspection of the insertion penetration site and catheter, without encouraging growth of bacteria. The film is configured with an open aperture located directly over and surrounding the insertion penetration site, to provide continual aeration and allow the incision site to remain uncovered and accessible to ambient air, and thus remaining dry, preventing accumulation and maintenance of a warm moist environment, discouraging growth of bacteria, and decreasing relative risk of penetration site infection. The surrounding film is transparent for visual inspection, and is adhesive and large enough to serve as an efficient anchor to prevent accidental dislodgement of the catheter, but is no longer an infection hazard.

Claim 8
Dependent Claim
154 words
A process for securing a catheter to a patient with transparent film without increasing relative risk of infection, comprising the steps of: selecting transparent, self-adhesive film for covering a portion of the catheter and a portion of the patient's body; shaping said film to form an open aperture over the skin penetration site of said catheter which provides direct, unobstructed aeration to said site when said film is applied to said catheter and body, for allowing said site and said patient's surrounding skin to remain dry wherein said film comprises means for significantly inhibiting growth of bacteria; aligning and positioning said aperture over and around said penetration site when said film is covering said portion of said catheter and body; and applying and pressing said self-adhesive film into position onto said catheter and body, wherein said film adheres to said catheter and body and comprises sole means for securing said catheter to said body.
Claim 9
Dependent Claim
154 words
A process for securing a catheter to a patient with transparent film without increasing relative risk of infection, comprising the steps of: selecting transparent, self-adhesive film for covering a portion of the catheter and a portion of the patient's body; shaping said film to form an open aperture over the skin penetration site of said catheter which provides direct, unobstructed aeration to said site when said film is applied to said catheter and body, for allowing said site and said patient's surrounding skin to remain dry wherein said film comprises means for significantly inhibiting growth of bacteria; aligning and positioning said aperture over and around said penetration site when said film is covering said portion of said catheter and body; and applying and pressing said self-adhesive film into position onto said catheter and body, wherein said film adheres to said catheter and body and comprises sole means for securing said catheter to said body.
