Laboratory sample distribution system, laboratory system and method of operating
A laboratory sample distribution system is presented. The laboratory sample distribution system comprises a plurality of container carriers. The container carriers each comprise at least one magnetically active device such as, for example, at least one permanent magnet, and carry a sample container containing a sample. The system further comprises a transport plane to carry the multiple container carriers and a plurality of electro-magnetic actuators stationary arranged below the transport plane. The electro-magnetic actuators move a container carrier on top of the transport plane by applying a magnetic force to the container carrier. The system also comprises at least one transfer device to transfer a sample item, wherein the sample item is a container carrier, a sample container, part of the sample and/or the complete sample, between the transport plane and a laboratory station such as, for example, a pre-analytical, an analytical and/or a post-analytical station.
1. A laboratory sample distribution system, the laboratory sample distribution system comprising:
a plurality of container carriers, each container carrier having a sample container containing a sample, wherein each container carrier comprises at least one magnetically active device;
a transport plane to carry the plurality of container carriers;
a plurality of electro-magnetic actuators stationary arranged below the transport plane, wherein the plurality of electro-magnetic actuators moves a container carrier on top of the transport plane by applying a magnetic force to the container carrier and wherein the plurality of electro-magnetic actuators moves the container carrier from a start location to a destination location; and
at least one transfer device arranged to transfer a sample item between a transfer location on the transport plane and a laboratory station,
wherein the transport plane comprises at least one transfer area located adjacent to the at least one transfer device, wherein the transfer location is located inside the transfer area, wherein a size of the transfer area is dynamically changed in response to a number of container carriers waiting for processing by the laboratory station.
2. The laboratory sample distribution system according to claim 1 , further comprising,
a container carrier conveyor functionally coupled to the transport plane, the container carrier conveyor being arranged to convey container carriers not placed on top of the transport plane.
