Title: Suction blister sampling

Abstract: There is disclosed an apparatus (1) for use in a suction blister technique of sampling fluid from the human or animal body. The apparatus (1) comprises a cup (2) defining a chamber and having a rim portion (3) defining an aperture (5) communicating with the chamber. An annular flange (6) extends outwardly from the rim portion (3) whereby in use the flange (6) is sealingly attached to the body such that an area of skin closes the aperture (5). A ducted portion (11) is connected to the cup (2) and defines duct (12) which communicates with the chamber. The cup (2) further comprises a roof (4) which merges with the rim portion (3) and is formed of a resiliently deformable material having a shape memory which urges the roof (4) into an expanded configuration in which the roof (4) is held clear of the aperture (5). The roof is however deformable to a collapsed configuration in which it is proximal to the aperture (5).
