Embodiment Construction

[0138] exist Figure 2a and 2b In the embodiment of the present invention, the hand-held fluid transfer device is a laboratory pipette, hereinafter pipette 1, 1'. Such as Figure 2a As shown in , the pipette is configured to be held by one hand of the user at the handle section 10a of the body 10 of the pipette. The handle 10a extends into the upper half of the pipette from around a center line C, which indicates the geometric center point of the pipette along the A axis. The body 10 of the pipette has an elongated shape extending along an axis A and has a length L measured along the axis A. As shown in FIG. Line C marks the center of the pipette along axis A. Axis A is also the axis of symmetry of a piston (not shown) located inside the pipette which is driven by an electric drive (not shown) to aspirate and / or discharge a liquid sample contained in a sample transfer container (here pipette tip 30). Forming an airtight connection in a conventional manner, the tip 30 plu...

Abstract

The present invention relates to a handheld fluid transfer device, more specifically a pipette or a repeating pipette, and a laboratory system comprising the handheld fluid transfer device, the handheld fluid transfer device comprising: a control device including a data processor, the The data processor is capable of executing a control program to control at least one electronically controllable function of a hand-held fluid transfer device using input data; user interface means for receiving user input, the user interface means including motion sensor means for measuring hand-held Motion data of the fluid transfer device, and for providing at least one sequence of motion data comprising subsequently measured motion data; a motion data memory for storing at least one sequence of motion data; an evaluation device configured to be based on at least one motion Evaluation of data sequences to determine input data. The invention still further relates to a method for operating a fluid transfer device or laboratory system.

Description

technical field [0001] The present invention relates to a handheld fluid transfer device, a laboratory system comprising the handheld fluid transfer device, and a method for operating the handheld fluid transfer device or the laboratory system. Background technique [0002] Such handheld fluid transfer devices are commonly used in medical, biological, biochemical, chemical and other laboratories. They are used in laboratories for transport and transfer of fluid samples with small volumes, especially for precise metering of samples. In a hand-held fluid transfer device, a liquid sample is drawn, for example by negative pressure, into a pipette container (eg, a pipette tip), stored there and retransmitted from the pipette container at the destination. The handheld fluid transfer device uses at least one control parameter (in particular an operating parameter) which at least affects or controls the operation of at least one function of the fluid transfer device. Hand-held flu...
