Abstract
In one embodiment, an anal pulse oximeter device is characterized by an anal canal surface; and a rectal-vault cuff having a leading portion and a trailing portion, the trailing portion substantially proximate to said anal canal surface. In another embodiment, a method of using a pulse oximeter device is characterized by positioning an insertion end of the pulse oximeter device against an anus; advancing the pulse oximeter device until a rectal-vault cuff of the pulse oximeter device substantially clears an internal anal sphincter; and withdrawing the pulse oximeter device until the rectal-vault cuff of the pulse oximeter device contacts a rectal vault. In another embodiment, a method of manufacturing a pulse oximeter device is characterized by attaching a rectal-vault cuff, the rectal-vault cuff having a leading portion and a trailing portion, such that the trailing portion is substantially proximate to an anal canal surface. In various embodiments the anal canal surface is an anatomical anal canal surface, while in other embodiments the anal canal surface is a surgical anal canal surface.
