摘要： A technique for separating components of a microfluid, comprises a self-intersecting micro or nano-fluidic channel defining a cyclic path for circulating the fluid over a receiving surface of a fluid component separating member; and equipment for applying coordinated pressure to the channel at a plurality of pressure control areas along the cyclic path to circulate the fluid over the receiving surface, applying a pressure to encourage a desired transmission through the separating member, and a circulating pressure to remove surface obstructions on the separating member. The equipment preferably defines a peristaltic pump. Turbulent microfluidic flow appears to be produced.

摘要： A pumping mechanism is disclosed that includes a plurality of peristaltic pumping actuators configured to selectively and sequentially compress adjacent portions of a first portion of an at least partially compressible pumping element having an inlet that is upstream of an outlet. The plurality of pumping actuators are further configured to reciprocate at a common drive frequency with a first phase offset between each adjacent pair of pumping actuators. The pumping mechanism also includes at least one compensation actuator arranged to selectively compress a second portion of the at least partially compressible pumping element that is disposed between the first portion and the outlet. The at least one compensation actuator is configured to reciprocate at an optimal displacement and at a modulation frequency that is an integer multiple of the fundamental drive frequency and with a second phase offset between the at least one compensation actuator and the adjacent pumping actuator.

摘要： A metering system for metering a liquid has an electric motor (32) for setting a desired feed rate by modifying the rotation speed of the electric motor. It furthermore has an eccentric drive (52, 56), drivable by said electric motor (32), for a pump (53) that has two delivery directions. It also has a pump ring (62) made of an elastomeric material and a stationary ring (70) which is arranged relative to the pump ring (62) and to the eccentric drive (52, 56) in such a way that a pump chamber (120), extending in a circumferential direction, is formed between the stationary ring (70) and pump ring (62), which chamber changes shape upon rotation of the electric motor (32) in order to deliver a liquid to be metered through the pump chamber (120). A stationary seal (142) is provided in the pump chamber (120), between two fluid ports.

摘要： The pump is provided with a plurality of pumping chambers (2) and electrically activatable valves (14). An elastic membrane (3) is arranged in each pumping chamber (2) and divides the same into a first and a second chamber section (2a, 2b). Each valve (14) is connected to the second chamber section (2a) of a pumping chamber. When a pressure drop is applied over the valve (14) and the valve (14) is activated (i.e. opened), the pressure in the second chamber section (2b) changes, which causes the membrane (3) to move, which in turn leads to a change of the volumes of both chamber sections. This e.g. allows to pump well-defined amounts of fluid from the chamber sections (2a) to a drug dispensing device.

摘要： A cassette (18) is provided having an elastomeric sheet (20) that is bonded or mechanically attached to a rigid substrate (22). A flow channel (27) is molded into the rigid substrate that corresponds to a flow channel (26) molded into the elastomeric sheet. The cassette is used in combination with a peristaltic pump (10) having pump head rollers (16) that are mounted radially from the axis of rotation of the pump motor (12) so as to compress the elastomeric flow channels against the rigid substrate during operation. The flow channels (27) molded into the rigid substrate have smooth, fluid lines free from sharp edges and abrupt direction changes and correspond with the fluid channels (26) molded into the elastomeric sheet so as to provide a transition region (34) with a relatively constant cross-section over its entire length that approximates to the cross-sectional area ofthe flow channels (27) molded into the rigid substrate and the fluid channel (26) molded into the elastomeric sheet, so that the entire fluid path is of relatively constant cross-sectional area.
