Abstract

A diagnostic system with a handling system that has a loading bay to receive and hold a plurality of carriers. An identification device is configured to identify an identifying feature of the carriers to determine the type of contents loaded on each carrier. A transporter transports the carriers from the loading bay to a first or second location depending on the determined type of contents on each carrier. The transporter has random access to the plurality of carriers in the loading bay. A diagnostic process is conducted using the contents. A carrier, such a for reagents, has one or more holding portions, at least one of which can be moved or rotated with respect to the body of the carrier for mixing or stirring the contents of a container coupled therewith. Also, a retention member can be associated with a positioning device, such as a carousel, to lock and unlock the carrier with respect thereto.

First claim

What is claimed is:

1. A carrier handling system for an assay testing diagnostic analyzer, comprising:
a loading rack comprising a first loading bay and a second loading bay, each of the first loading bay and the second loading bay to receive and hold a carrier;
an identification device to identify a feature associated with the carrier to determine a type of a content loaded on the carrier;
a positioner having an opening to receive the carrier, the positioner to move the carrier from a first position to a second position;
a transporter; and
a computer controller including software programmed to control the transporter to automatically:
move the carrier from the first loading bay or the second loading bay to a first location or a second location depending on the type of the content to perform a diagnostic process using the content by randomly accessing the carrier in the first loading bay and the second loading bay,
pick up the carrier from the loading rack,
place the carrier into the loading rack,
place the carrier onto the positioner,
pick up the carrier from the positioner,
present the carrier to the identification device, and
scan the feature to determine the presence of the carrier in a tray or a slot in the loading rack.

2. The carrier handling system of claim 1 , wherein the identification device is to identify the content of the carrier as being a sample or a reagent to be used in the diagnostic process, the identification device being associated with the transporter such that the transporter is to move the sample to the first location and the reagent to the second location.

3. The carrier handling system of claim 2 , wherein the identification device is to identify the type of the content independently of information on where in the loading rack the carrier is located.

4. The carrier handling system of claim 1 , wherein the computer controller is to cause the transporter to move the carrier from a third loading bay in the loading rack to the first location or the second location.

5. The carrier handling system of claim 1 , wherein the first location comprises a first carrier support disposed for access by a diagnostic module that is to perform the diagnostic process, and wherein the computer controller is to cause the transporter to move the carrier from the first loading bay or the second loading bay to the first carrier support.

6. The carrier handling system of claim 5 , wherein the computer controller is to cause the transporter to move the carrier from the first location to another location on the first carrier support.

7. The carrier handling system of claim 6 , wherein at least two carriers are disposed on the first carrier support at the same time.

8. The carrier handling system of claim 5 , wherein the first carrier support includes the positioner to receive and move the carrier such that the diagnostic module can test contents in the carrier.

9. The carrier handling system of claim 1 , wherein the feature comprises an optically readable feature, and the identification device comprises an optical reader capable of reading the optically readable feature.

10. The carrier handling system of claim 1 , wherein the feature comprises a physical characteristic of the carrier.

11. The carrier handling device of claim 1 , wherein the computer controller is to control the movement of the transporter based on input data and a preprogrammed priority order for processing a plurality of samples.

12. The carrier handling device of claim 1 , wherein the carrier is to hold a container that contains a reagent, at least one of the carrier or the container having the feature to identify the content as being the reagent.

13. The carrier handling device of claim 1 , wherein the positioner includes an elongated track.

14. The carrier handling device of claim 1 , wherein the positioner includes a driving means.

15. The carrier handling device of claim 1 , wherein the transporter includes a plurality of sensors to monitor operation of the system.

16. The carrier handling device of claim 15 , wherein the sensors are to determine the presence of the carrier in at least one of the tray, the slot or the positioner.

17. The carrier handling device of claim 15 , wherein the sensors are to verify correct alignment between the transporter and one or more of the slot of the loading rack or the opening of the positioner.

18. The carrier handling device of claim 15 , wherein the sensors are to monitor the horizontal, rotational and vertical motions of the transporter.

19. The carrier handling device of claim 15 , wherein the sensors are to verify proper engagement between the carrier and the transporter.

20. The carrier handling device of claim 1 , wherein in the first position the carrier is located a first distance from a first end of the positioner and in the second position the carrier is located a second distance from the first end of the positioner.

21. The carrier handling device of claim 1 , wherein the positioner is to receive at least three carriers.

22. The carrier handling device of claim 21 , wherein the positioner comprises an elongated track and the three carriers are to be disposed along the elongated track.

23. A diagnostic system, comprising:
the carrier handling system of claim 1 ; and
a diagnostic module to conduct the diagnostic operation.
