DEVICE FOR THE HANDLING OF SAMPLES CONTAINING LIQUID COMPONENTS

摘要

The present invention relates to a device for handling samples containing liquid components, especially for performing sample-taking from blood, which contains a retaining part-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). The characteristic feature of the invention is that the drive member (31) of the drive unit (30) has a single drive motor (31a), while the movement-transfer part-unit (32) is formed by the set of a carrying structure (33) embedded so that it may rotate around the rotation axles (33a, 33aa) of the movement-transfer part-unit (32), and a drive-transfer unit (34) inserted between the carrying structure (33) and the drive motor (31a), furthermore, the carrying structure (33) has a first moving element (33b) and a second moving element (33d), where from among the first moving element (33b) and the second moving element (33d), the first has a first control body (33c) falling outside of its rotation axle (33a), while the second has a second control body (33e) working together with the first control body (33c) and falling outside of its own rotation axle (33aa), and with the help of the second control body (33e) working together with the first control body (33c), the first moving element (33b) and the second moving element (33d) have a periodical, movement-transfer positive coupling link with each other, furthermore, of the first moving element (33b) and the second moving element (33d) of the carrying structure (33), one of them is connected to a sliding fitting (21) connected to the retaining part-unit (20) serving to hold the storage unit (1).
