摘要： The invention relates to a pumping device comprising a working chamber and a piston provided to slide in said working chamber so as to vary the useful volume of the chamber during pumping, comprising anti-rotation means for the piston. Advantageously, said anti-rotation means comprise an index (107) mounted radially with respect to the axis of the piston and the device comprises a longitudinal slot (108), said index being provided so as to move in said slot. Advantageously, the index (107) has two approximately parallel planar faces that extend longitudinally.

摘要： The invention relates to a pumping device comprising: a housing (1) whose front face (2) is at least partly formed by a block of transparent material (3), this block (3) containing a number of machine-drilled holes including at least one blind hole (4) forming a work chamber (17), at least one hole forming an admission and/or exhaust channel (5) leading into the blind hole (4), two through channels (6, 7) whose orifices (10, 11) on the front face (8) of the block (3) are fitted with hydraulic hose connection means, two solenoid valves, a plunger (15) sliding leaktightly in a bearing (16) fitted to the orifice of the blind hole (4), this plunger (15) defining with said blind hole (4) a volume that varies as a function of the axial position of the plunger (15), and a module connected to the base of the plunger for moving the plunger (15) translationally. The invention applies to the pipetting, dilution, rinsing and/or dispensing of samples, that is to say irrespective of the envisaged sections of volume.

摘要： The invention relates to a device (1) for monitoring sample-collection carried out using a piston pump (3, 8) such as a syringe, characterised in that said device includes a pressure sensor (11) close to the suction and/or delivery opening (6). Said device is in particular suited for use in an analysis automaton, in particular for analysing a blood sample. Such a sensor guarantees that the liquid to be analysed is properly sucked up, in particular that no air is sucked up and that neither the suction or delivery sides are blocked.
