Abstract

An analyzer for use with in vitro diagnostics includes one or more containers. Each container includes a container body configured to hold one or more fluids, a closure device disposed on the container body and housing a movable cannula, and a sealing portion configured to seal off the one or more fluids in the container body from matter outside the container body when the sealing portion is closed. The system also includes one or more pick and place devices configured to move the one or more containers between different locations. The movable cannula is configured to move downward responsive to a force from the one or more pick and place devices and cause an opening in the sealing portion.

First claim

What is claimed is:

1. An analyzer for use with in vitro diagnostics comprising:
one or more containers comprising:
a container body configured to hold one or more fluids;
a closure device disposed on the container body and housing a movable cannula; and
a sealing portion attached to one of the container body or the closure device, and configured to seal off the one or more fluids in the container body from matter outside the container body when the sealing portion is closed; and

one or more pick and place devices configured to move the one or more containers between different locations;
wherein the movable cannula is configured to move downward responsive to a force from the one or more pick and place devices and cause an opening in the sealing portion.

2. The analyzer of claim 1 , further comprising a fluid contacting device configured to move downward through the opening in the sealing portion, contact the one or more fluids and retract upward through the opening in the sealing portion,
wherein the movable cannula is further configured to cause the opening in the sealing portion to have a size sufficient to prevent the fluid contacting device from contacting the sealing portion.

3. The analyzer of claim 2 , wherein the fluid contacting device is further configured to aspirate a portion of the one or more fluids in the container body.

4. The analyzer of claim 2 , wherein the fluid contacting device is further configured to sense a level of the one or more fluids in the container body.

5. The analyzer of claim 1 , further comprising:
one or more sensors that sense position information indicating one or more positions of the one or more pick and place devices; and
a controller configured to control the one or more pick and place devices to move the cannula between a retracted position and an extended position based on the sensed position information.

6. The analyzer of claim 1 , wherein the one or more containers further comprises a container holding portion configured to be held by the one or more pick and place devices to move the one or more containers, the container holding portion having a recessed portion disposed on a top surface of the container body and a rib portion extending between opposing walls of the recessed portion.

7. The analyzer of claim 1 , wherein the analyzer is part of automation system having a plurality of analyzers.

8. A fluid container comprising:
a container body configured to hold one or more fluids;
a closure device disposed on the container body and housing a movable cannula;
a sealing portion attached to one of the container body or the closure device, and configured to seal off the one or more fluids in the container body from matter outside the container body when the sealing portion is closed;
a retracted position holding mechanisms configured to hold the cannula in a retracted position; and
an extended position holding mechanism configured to hold the cannula in an extended position;
wherein the movable cannula is configured to move in a downward direction responsive to a downward force and cause an opening in the sealing portion, when the downward force is sufficient to overcome a resistance that holds the cannula in the retracted position in which the cannula does not open the sealing portion, the downward force moving the cannula to the extended position when the cannula opens the sealing portion.

9. The fluid container of claim 8 , wherein the sealing portion is attached to a bottom surface of the closure device.

10. The fluid container of claim 8 , wherein the sealing portion is housed in the closure device.

11. The fluid container of claim 8 , wherein the sealing portion is a film membrane.

12. The fluid container of claim 8 , wherein the sealing portion is a molded membrane.

13. The fluid container of claim 8 , wherein the closure device is removably coupled to the container body.

14. The fluid container of claim 13 , wherein the closure device comprises threading and is rotatably coupled to the container body via the threading.

15. The fluid container of claim 13 , wherein the closure device is a snap cap.

16. The fluid container of claim 8 , wherein the closure device is fixed to the container body.

17. A closure device for use with a container comprising:
a closure device body configured to be coupled to the container;
a movable cannula housed in the closure device body and configured to move downward relative to the closure device body from a retracted position to an extended position, responsive to a downward force exerted on the cannula;
a sealing portion housed in the closure device body and configured to seal off the container when the sealing portion is closed;
wherein the downward force exerted on the cannula causes an opening in the sealing portion, when the downward force is sufficient to overcome a resistance that holds the cannula in the retracted position in which the cannula does not open the sealing portion, the downward force moving the cannula to the extended position when the cannula opens the sealing portion.

18. The closure device of claim 17 , further comprising a coupling portion configured to couple the closure device body to the container.

19. The closure device of claim 17 , wherein a bottom surface of the cannula is sloped toward a bottom of the closure device body.

20. The closure device of claim 17 , wherein a bottom surface of the cannula comprises one or more pointed edges.

21. A method for opening a container, comprising:
using a pick and place device to move a fluid container between different locations;
applying a downward force with the pick and place device to a cannula housed in a closure device disposed on the fluid container;
moving the cannula in a downward direction, response to the downward force, toward a sealing portion attached to one of the fluid container or the closure device; and
providing an opening in the sealing portion with the cannula by contacting the sealing portion with the cannula.

22. The method of claim 21 , further comprising:
moving a fluid contacting device through the opening in the sealing portion;
contacting one or more fluids in the fluid container with the fluid contacting device; and
retracting the fluid contacting device back through the opening in the sealing portion,
wherein the opening of the sealing portion further comprises causing the opening in the sealing portion to have a size sufficient to prevent the fluid contacting device from contacting the sealing portion.

23. The method of claim 22 , wherein the contacting of the one or more fluids in the fluid container further comprises at least one of: (i) aspirating the one or more fluids in the fluid container into the fluid contacting device, and (ii) sensing a level of the one or more fluids in the fluid container.
