5 . The securement device of claim 1 further comprising:
a suction port having a dome that is generally hemispherical in shape and a flange that extends from the dome wherein the flange is secured to the exposed region of the adhesive.
6 . The securement device of claim 1 further comprising:
tubing that is adjacent to the film wherein the tubing extends from the second aperture.
7 . A method for assembling a securement device for use in negative pressure wound therapy wherein the securement device has a release strip, a release layer, a film with an adhesive and a back layer, wherein the release strip, the release layer, the film, the adhesive and the back layer are generally planar and generally parallel with respect to each other, the method comprising the steps of:
coating a top surface of the film with an adhesive wherein the film has a first aperture that extends through the film;
attaching the back layer to the film wherein the back layer covers the film;
securing the release layer to the adhesive wherein the release layer has a second aperture that extends through the release and that is larger than the first aperture and further wherein the release layer covers the adhesive such that a ring of the adhesive is exposed between the first aperture and the second aperture; and
securing the release strip to the ring of the adhesive wherein the release strip has a section that is unsecured to the ring of adhesive and that contacts the release layer.
8 . The method of claim 7 further comprising the step of:
grasping the section of the release strip.
9 . The method of claim 7 further comprising the step of:
pulling the section of the release strip in a direction away from the film to remove the release strip.
10 . The method of claim 7 further comprising the step of:
attaching a suction port to the ring wherein the suction port has a flange that covers the ring.
11 . The method of claim 7 further comprising the step of:
removing the release layer from the film.
12 . The method of claim 7 further comprising the step of:
peeling the back layer from the film.
13 . A securement device for use in negative pressure wound therapy, the securement device comprising:
a film having a top surface with an adhesive and bottom surface positioned opposite to the top surface wherein the film has a first perimeter and has a first aperture having a first diameter wherein the first aperture extends through the film;
a release layer secured to the film wherein the release layer has a second perimeter and is substantially parallel to the film wherein the release layer has a second aperture that extends through the release layer wherein the first perimeter and the second perimeter are aligned with respect to each other wherein the second aperture has a second diameter that is greater than the first diameter so that the film has a ring of adhesive that is exposed between the first aperture and the second aperture;
a release strip having a third aperture that extends through the release strip and having a third perimeter defined by a first edge, a second edge, a third edge and a fourth edge wherein the first edge is positioned opposite to the second edge and the third edge is positioned opposite to the fourth edge and further wherein the first edge and the second edge are generally perpendicular to the third edge and the fourth edge wherein the first edge and the second edge extend along the second perimeter wherein the release strip contacts the release layer and is adhered to the ring of adhesive and further wherein the release strip has a section that extends beyond the ring of adhesive and is unsecured to the ring of adhesive; and
a back layer having a fourth aperture that extends through the back layer wherein the back layer is secured to the film wherein the film is between the back layer and the release layer and further wherein the back layer has a fourth perimeter that is aligned with respect to the second perimeter.
14 . The securement device of claim 13 further comprising:
tabs secured to the adhesive on the top surface of the film wherein the tabs are positioned on opposite ends of the film and further wherein the tabs are between the release layer and the back layer.
