Title: Drainage system for incisions or wounds in the body of an animal

Abstract: The invention provides a combination of a sheet of thin pliable material adapted to be placed in sealing engagement with the skin of a patient in the location of a body opening made by an incision or wound, with the sheet being adapted to have an aperture formed therein to expose the opening, together with a removable cap preferably of transparent plastic material which can be adhesively secured to the outer face of the sheet. Drains placed in the body opening can be observed through the cap and the opening can be treated and the tubes withdrawn in increments by simply removing the cap which thereafter can be replaced.
