A tube segment sampler system (10) for withdrawing a fluid sample from a tube segment (100), the sampler (10) having a first tube piercing member (28) for piercing the tube segment at a first location and a second tube piercing member (28) for piercing the tube segment at a second location so as to allow air to be drawn into the tube segment (100) through one of the openings made by one of the piercing members (28) while fluid is withdrawn through the other of the openings.

An apparatus for eliciting a blood sample is presented having a lancet for lancing a body part of a user and a cleaning member of absorbent material operable to clean a surface of the body part, the apparatus being configured such that in use the lancet is moved to lance a body part of a user and subsequently the cleaning member is moved to contact the body part of the user so as to remove blood from the surface of the body part prior to collection of the blood sample from the surface of the body part.

An apparatus for eliciting a blood sample comprises a housing, an aperture in a wall of the housing, an aperture cover moveable between a first position in which the aperture is covered and a second position in which the aperture is uncovered, the aperture cover comprising a sealing member configured to seal the aperture on a first side of the wall when the aperture cover is in the first position and a user-contactable part extending from the sealing member through the aperture to the second side of the wall and configured to allow a user to move the aperture cover between the first and second positions.

The present invention includes a filter apparatus including a filtration unit; and a collection chamber in fluid communication with the filtration unit; wherein a vacuum draws the biological fluid through the apparatus; and wherein selected biological material comprised by the biological fluid is separated from a remainder of the biological fluid.
