Abstract

A system for rupturing a vacuum in a medical imaging device. The system includes a vacuum plug attached to the medical imaging device and configured to retain a vacuum in the medical imaging device. A puncture tool is configured to puncture the vacuum plug to rupture the vacuum in the medical imaging machine. A puncture tool retainer removably couples the puncture tool to the medical imaging device.

First claim

What is claimed is:

1. A system for rupturing a vacuum in a medical imaging device, the system comprising:
a vacuum plug attached to the medical imaging device and configured to retain a vacuum in the medical imaging device;
a puncture tool configured to puncture the vacuum plug to rupture the vacuum in the medical imaging machine; and
a puncture tool retainer that removably couples the puncture tool to the medical imaging device.

2. The system according to claim 1 , wherein the puncture tool retainer removably couples the puncture tool to the vacuum plug.

3. The system according to claim 2 , wherein the vacuum plug defines a rupture passage therethrough, further comprising a rupture disk that sealingly covers the rupture passage to retain the vacuum in the medical imaging device, wherein the vacuum plug has an outer surface and an inner surface with the rupture passage defined therethrough, and wherein the rupture disk is coupled to the inner surface of the vacuum plug.

4. The system according to claim 3 , wherein the puncture tool is configured to puncture the rupture disk inwardly, away from the outer surface.

5. The system according to claim 3 , wherein the rupture disk is a reverse buckling rupture disk having a convex portion with a center extending towards the upper surface of the vacuum plug.

6. The system according to claim 1 , wherein the puncture tool has a handle opposite a puncture tip, wherein a force is applied with the puncture tip via the handle to puncture the vacuum plug, wherein the handle defines a puncture tool retainer passthrough therein, wherein the vacuum plug defines a puncture tool retainer receiver therein, and wherein the puncture tool retainer extends through the puncture tool retainer passthrough and is received within the puncture tool retainer receiver to removably couple the puncture tool to the vacuum plug.

7. The system according to claim 6 , wherein the puncture tool retainer is a Christmas tree type plug.

8. The system according to claim 6 , wherein the puncture tool when removably coupled to the vacuum plug is perpendicular to when used to puncture the rupture disk.

9. The system according to claim 6 , wherein the puncture tool retainer passthrough and the puncture tool retainer receiver are parallel when the puncture tool is removably coupled to the vacuum plug.

10. The system according to claim 6 , wherein the puncture tip of the puncture tool is cylindrical and defines an opening therein.

11. The system according to claim 6 , wherein the puncture tip is angled.

12. The system according to claim 1 , wherein the puncture tool is non-metallic.

13. The system according to claim 1 , wherein the medical imaging machine has a cover, and wherein the vacuum plug and the puncture tool are configured to be hidden from view by the cover when the puncture tool is removably coupled to the medical imaging device.

14. A system for rupturing a vacuum in a magnetic resonance imaging device, the system comprising:
a vacuum plug configured to be coupled to the magnetic resonance imaging device, the vacuum plug having parallel outer and inner surfaces and perpendicularly defining a rupture passage therethrough, wherein a puncture tool retainer receiver is also defined within the outer surface;
a rupture disk that sealingly covers the rupture passage defined within the vacuum plug to retain the vacuum in the magnetic resonance imaging device;
a puncture tool extending from a handle to a puncture tip, the puncture tip being angled and configured to puncture the rupture disk when a force is applied via the handle by the puncture tip upon the rupture disk; and
a puncture tool retainer receivable within the puncture tool retainer receiver such that the puncture tool retainer removably couples the puncture tool to the vacuum plug;
wherein the vacuum is ruptured when the rupture disk is punctured.

15. The system according to claim 14 , wherein the handle defines a puncture tool retainer passthrough therein, and wherein the puncture tool retainer extends through the puncture tool retainer passthrough and is received within the puncture tool retainer receiver to removably couple the puncture tool to the vacuum plug.

16. The system according to claim 15 , wherein the puncture tool retainer passthrough and the puncture tool retainer receiver are parallel when the puncture tool is removably coupled to the vacuum plug, and wherein the puncture tool when removably coupled to the vacuum plug is perpendicular to when used to puncture the rupture disk.

17. A magnetic resonance imaging (MRI) device comprising:
a vacuum plug attached to a body of the MRI device and configured to retain a vacuum in the MRI device;
a puncture tool configured to puncture the vacuum plug to rupture the vacuum in the MRI device; and
a puncture tool retainer that removably couples the puncture tool to the MRI device.

18. The MRI device of claim 17 , wherein the puncture tool retainer removably couples the puncture tool to the vacuum plug, further comprising a removable cover that covers the vacuum plug.

19. The MRI device of claim 18 , wherein the vacuum plug defines a rupture passage therethrough, further comprising a rupture disk that sealingly covers the rupture passage to retain the vacuum in the MRI device, wherein the vacuum plug has an outer surface and an inner surface with the rupture passage defined therethrough, and wherein the rupture disk is coupled to the inner surface of the vacuum plug.

20. The MRI device of claim 19 , wherein the puncture tool extends from a handle to a puncture end, the puncture end being configured to puncture the rupture disk when a force is applied via the handle by the puncture tip upon the rupture disk, wherein the handle defines a puncture tool retainer passthrough therein, wherein the vacuum plug defines a puncture tool retainer receiver therein, and wherein the puncture tool retainer extends through the puncture tool retainer passthrough and is received within the puncture tool retainer receiver to removably couple the puncture tool to the vacuum plug.
