  • Patent number: 5402997
    Abstract: The device comprises a support element (6) arranged in parallel with the free end of a cassette lid (1b) which is to be opened. The support element is driven by a lever gear (7, 8, 9, 33, 34, 35) and, guided on arms (2, 3), can be lifted and lowered. Spring-biased pressure bolts (19, 20) guided on the support element (6) serve to reduce the pressure exerted on the cassette locking mechanism (1c, 1d) during unlocking as well as to close the cassette 1. A mounting plate (23) on which an unlocking member (25, 36) and its driving rotary magnet (26) are arranged is spring-biased into contact with the pressure bolts (19, 20). Moreover, an opening element (15) with check arms (15a, 15b) associated with the cassette lid (1b) is also pivotably mounted on the support element (6) and can be brought into an operative position in response to the position of the unlocking member (25, 36) and the position of the support element (6) respectively.

  • Patent number: 5384947
    Abstract: A stack of plastic articles and a process of forming the stack are disclosed. Preferably the stack is of heat-fusible plastic slide elements for use in a diagnostic analyzer, the elements being temporarily and non-destructively fused together so that the stack can be used free of a cartridge. In another embodiment, the stack can be of any plastic article temporarily fused to adjacent elements, one side edge of each element bearing a colorant and another bearing no colorant, so that a bar code for the stack is inherently formed simply by rotating each element to project outwardly the colored side edge or the side edge lacking colorant, prior to fusing the elements together.

  • Patent number: 5380666
    Abstract: A method is described for centering and aspirating containers filled with a body fluid and having different diameters, in which the containers are situated on a moveable tray having receptacles for holding a plurality containers of different diameters. The tray is then placed in a pivotable transporter within an analyzer having a scanning and an aspiration station situated along a transport path of the transporter. Scanning elements at the scanning station sense and fix by contact the position of the container and tray respectively so as to locate the center of the container being scanned. Signals from sensing elements aligned with the scanning elements align and position an aspiration probe at the aspiration station to coincide with the centerline axis of the container in order to withdraw all of the body fluid contained therein, regardless of the container diameter.

  • Patent number: 5364591
    Abstract: There are described a device and method for doing confined reactions such as PCR amplification and detection, wherein solids (e.g., beads) used to obtain separation between bound and "free" label reagents, are transferred from region to region, specifically through a wash liquid so as to wash off the "free" label reagent from the solids. Separate chambers have dividers that are overcome by piercing or by liquification, to create passageways for the transfer of the solids. The passageways remain contained within the device.

  • Patent number: 5344610
    Abstract: An aspirator probe, such as is used with a disposable tip in a clinical analyzer. The probe is pivotable to allow for horizontal displacement error in seating the probe at a liquid-dispensing station. To reduce the amount of "tip flick" that occurs by pivoting the tip about the pivot point as the probe starts to withdraw from the liquid-dispensing station, the pivot point is located from the fulcrum at the liquid dispensing station, a distance that is at least five times the length of the disposable tip measured from the fulcrum.
