ABSTRACT:
An absorbent sleeve formed to fit over at least the distal portion of a finger to absorb fluids and remove debris from constrained areas of the body such as canals and cavities, or to apply fluid substances is disclosed. The sleeve has an upper and lower portion which may be of equal length. In a preferred embodiment, the upper and lower portion are of differing lengths with the lower portion having an appendage attached thereto to facilitate safe and convenient removal of the sleeve after use. The sleeve also preferably has a fluid impermeable layer between an external surface of the sleeve and an inserted finger to create a fluid barrier. The sleeve may have a friction enhancing member to prevent unintentional removal of the sleeve during use.
