Embodiment Construction

[0021] In the prior art magnetic conveyor system 10, as figure 1 As best shown, the magnetic coupling 12 mounted to the conveyor belt 14 includes a stationary magnet 15 magnetically coupled to a ferromagnetic member 16 of a sample rack 17 for moving the sample rack along a conveyor surface 18 . The sample rack 17 carries one or more sample containers 19 and comprises on its bottom a ferromagnetic member 16, eg a steel plate. Increasing the strength of the delivery magnets will improve delivery reliability. The inventors herein realized that this prior art system would accelerate the sample holder 17 unacceptably quickly as the magnet 15 of the magnetic coupling 12 approaches the sample holder 17 as the field strength of the transport magnet increases. This causes the sample holder 17 to bounce towards the magnetic coupling 12 and to spill the sample fluid contained in the open sample container 19 . Such spillage would be unacceptable because it would result in loss of patien...

Abstract

Disclosed are magnetic conveyor systems and apparatus having a magnetic coupling with a housing and moveable magnet therein. The moveable magnet is substantially constrained in one dimension and adapted to move in another. The moveable magnet is adapted to magnetically couple with an attracting portion of a sample rack and move the rack along a conveying surface. Ease of transfer of sample racks is provided while minimizing spillage from the open sample containers therein. Methods of operating the conveyor system are provided, as are other aspects.

Description

technical field [0001] The present invention generally relates to apparatus, systems and methods for transporting sample racks to and from clinical analyzers. Background technique [0002] When testing bodily fluid samples (or "samples") in automated testing systems (such as clinical analyzers), sample containers (such as test tubes, sample cups, bottles, etc.) can be transported in sample racks along a conveyor system to test system. One type of conveyor system is magnetically coupled to the sample rack to move the sample rack along the conveying surface. The act of magnetically coupling to the sample holder in operation causes the spillage of the fluid sample within the sample container. Accordingly, there is a need for devices, systems, and methods that may allow less disturbance of sample containers and sample racks as they are transported to and from clinical analyzers, thereby reducing the tendency to spill from sample containers. Contents of the invention [0003...
