Abstract: A controlled transfer biological sample material collection device is disclosed which comprises: a body; and a sample collection member for collecting the biological sample material (not shown), the body housing a sample storage medium for generally dry storage of the biological material, the collection member being moveable from an exposed position (shown in FIG. 8) where collection of a biological sample is possible, to a transfer position (shown in FIG. 9) which effects transfer of at least a portion of the collected sample to said medium. The device is characterized in that the body slideably supports the sample collection member, and in that the body or collection member include a ramp-like projection portion (116 FIG. 10) operable to force the collection member into the transfer position against the medium and to effect said transfer as the collection member slides within the body.

Abstract: A foot 200 for attachment to a leg 180 of a trolley frame 100 designed to assist a user of reduced mobility move about a floor 120. The foot 200 has a first state in which the foot presents a contact surface 224 having a frictional resistance that facilitates slidable contact between the foot 200 and the floor 120 when attached to the leg 180 and when in use, and a second state in which the foot presents an enhanced contact surface 252 having an increased frictional resistance between the foot and the floor to resist said slidable contact. The foot 200 is transferrable between the first and the second states in dependence on a downwardly directed force 190 being exerted by the user on the foot through the leg of the trolley frame to allow the trolley frame 100 to be slid or to resist sliding depending upon the state of the foot.
