Abstract
A method and a device for removing an analytic consumable product, in particular a test element, from a storage container having chambers which are sealed by foils from which the consumable product is pushed out by means of a plunger (7) can be optimized in that the magnitude of the thrusting force exercised by the plunger (7) during its forward motion can be controlled in dependence on the plunger (7) position.
Claims18
A device for removing a consumable analytic product from a storage container having at least one chamber for containing a consumable product, wherein each chamber has a removal opening for removal of a consumable product and an insertion opening disposed opposite to the removal opening for introduction of a plunger to transport the consumable product, wherein the removal opening and the insertion opening are sealed with foil for storing the consumable product and the plunger is displaced by a drive unit to remove the consumable product, wherein
- the device comprises a control unit controlling the magnitude of the thrusting force, which is exerted by the plunger during its forward motion for removal of the consumable product wherein the thrusting force is variable and dependent on the position of the plunger, the control unit comprising a mechanical path control with a helically wound control element which driven by a drive unit for rotation about a longitudinal axis of the control element to control the thrust of the plunger and which is connected to a carrier member so that the plunger is moved in the thrusting direction during rotation of the control element.
