This invention relates to moldable body patches to provide moisture protection for wound sites during for example showering.
Shower patches have been used in the past to cover wound sites but those have worked less than satisfactory. For example, typical prior art shower patches often involve square film pieces using 90° angle tear-away strips to reveal underlying adhesive that covers just the strip area, leaving a blank spot in each corner. The problem with such shower patches are two-fold. First, sharp angles on the patches seem to provide an increased propensity for moisture leakage due to the blank spot. Second, square angles also cause improper skin adherence.
Accordingly, it is a primary object of the present invention to provide an improved shower patch which may be easily applied, easily removed, and one which will not interfere with the underlying wound site during use.
Another objective of the present invention is to provide an improved shower patch for wound sites which has greater ease of application, which better fits the contour of the human anatomy, and which provides less propensity for leakage which allows moisture access to the underlying wound.
A method and means of accomplishing each of these objectives as well as others will become apparent from the detailed description of the invention which follows.
A preferred embodiment of the invention involves a moldable body patch to provide moisture protection for wound sites. The patch has a non-linear shaped medical grade film piece, preferably elliptical shaped, which has upper, lower and middle portions. Middle and lower portions have a backing paper removably adhered to the film piece while the upper portion has a pull tab permanently adhered to the upper portion. In use, the user removes the backing from the middle backing portion, removes the lower backing portion paper and applies the patch over the wound site with the tab appearing above the wound dressing. The elliptical shape fits the human anatomy, and since there is no adhesive directly underneath the wound site, there is no interference with the wound dressing. When finished the pull tab is pulled directly downward and the shower patch removed.
For purposes of promoting and understanding of the principles of the invention reference will be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated embodiment, and such further applications of the principles of the invention are contemplated as being within the scope of the invention, as are modification that would normally occur to one skilled in the art to which the invention relates. The limits of the invention are defined by the claims, not the description of the preferred embodiment.
Referring now more particularly to
The adhesive 20 is applied to coincide with the outer surface area of the middle backing paper 16 and the lower backing paper 18. Thus the window or central portion 22 of film piece 12 does not have adhesive on its backside.
The patch is conveniently packaged, and in some instances, five per package is typical. Typical dimensions are a coverage area of 5 inches by 8 inches or 3½ inches by 6 inches. It is best used when applied to clean, dry and shaved skin. Its shape allows it to conform to body contours and not stretch over the covered area. As a result, leakage is minimized.
Medical grade film which is used is hypoallergenic and biocompatible. It is thin and flexible to prevent tunneling in stressed areas and is preferably an ethyl vinyl acetate (EVA) film. The medical grade adhesive which is used is applied through a lamination process and has been through cytotoxicity and skin sensitization testing. It is biocompatible with the skin and not overly aggressive reducing the possibility of irritation. The inner paper backing which is used is set out in two pieces for easy removal. It can therefore be seen that the invention accomplishes at least all of its stated objectives.
This application is a Continuation of and claims priority to U.S. Ser. No. 11/127,923 filed May 12, 2005, herein incorporated by reference in its entirety.
