Abstract: A device for handling a sample containing liquid components comprises a housing, a retaining part-unit for holding a storage unit containing the sample, a drive unit for moving the retaining part-unit, and at least one sample-taking body located in the housing. The drive unit has a drive member and a movement-transfer part-unit connected tHereto, and the movement-transfer part-unit has at least one rotation axle. The drive member of the drive unit has a single drive motor, while the movement-transfer part-unit is adjacent to a carrying structure that rotates around the rotation axle(s) of the movement-transfer part-unit. A drive-transfer unit is inserted between the carrying structure and the drive motor, the carrying structure having first and second moving elements which have first and second control bodies, respectively, falling outside of first and second rotation axles, respectively. The first and second moving elements have a periodical, movement-transfer positive coupling link with each other.

Abstract: The present invention relates to a device for handling samples containing liquid components, especially for performing sample-taking from blood, which contains a retaining par-unit (20) serving to hold the storage unit (1) containing the sample (2), a drive unit (30) serving to move the retaining part-unit (20), as well as a housing (10) encompassing at least a part of the drive unit (30), and at least one sample-taking body (3) located in the internal space (11) of the housing (10), where the drive unit (30) has a drive member (31), and a movement-transfer part-unit (32) in connection with the drive member (31), and the movement-transfer part-unit (32) has at least one rotation axle (33a).

Abstract: The present invention relates to a flow cytometer (10) for in vitro assaying of human or animal whole blood and to an investigation method using the flow cytometer. Enhanced detection properties are achieved by it relative to the prior art cytometers of the same kind. Here, automated beam positioning is also solved. To these ends, collection of light scattered by the cellular components of human or animal whole blood and its transmission to suitable optical sensing elements take place by a coupling member with a particular end construction, in particular through one or more optical fiber bundles. Preparation of a blood sample for the assay, that is, mixing up said human or animal whole blood with appropriate reagents is performed by a hydro-pneumatical unit (12) of a particular design. Moreover, the actual assaying takes place in a flow cell (22) of a particular construction, which assists to improve the signal-to-noise ratio of the present flow cytometer.
