Sterilization packaging systems
Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a frame including a plurality of vertical members and a plurality of horizontal members, each vertical member and horizontal member having an inner side and an outer side; a sterilization wrap, a first portion of the sterilization wrap positioned adjacent the inner side of each vertical member and each horizontal member to define a volume and an opening to access the volume; and a lid for sealing the volume against an ingress of contaminants. Additionally, a sterility gauge for signaling whether the volume is sealed against contaminants also may be provided. Exemplary sterilization packaging systems may include other features as well.
1. A sterilization packaging system, comprising:
a container defining a vertical direction and a volume for containing items to be sterilized, the container having a perimeter defining an opening through which the items to be sterilized are placed in the container; and
a sealing assembly, the sealing assembly including
a sheet of sterilization material, and
a clamp for sealing the sheet of sterilization material against the container, the clamp having an open position and a clamped position, the clamp extending about the perimeter of the container when the clamp is in the clamped position, the clamp comprising a horizontal portion that defines a window, the horizontal portion extending inward with respect to the perimeter of the container such that the horizontal portion is positioned over the opening, wherein the vertical portion projects vertically above the horizontal portion, wherein the horizontal portion is planar, and
wherein the clamp curves from the vertical portion vertically above the horizontal portion to the horizontal portion to define a curved transition from the vertical portion to the horizontal portion.
2. The sterilization packaging system of claim 1 , wherein the clamp further comprises a vertical portion extending along the vertical direction, and wherein the vertical portion intersects with the horizontal portion such that the clamp has an L-shaped cross-section.
3. The sterilization packaging system of claim 2 , wherein the vertical portion of the clamp is positioned adjacent one or more vertical walls of the container.
4. The sterilization packaging system of claim 1 , wherein the curved transition defines a depression, the depression configured such that a second sterilization packaging system may be stacked on top of the clamp and received in the depression.
5. The sterilization packaging system of claim 1 , wherein the sheet of sterilization material extends between the clamp and the container such that the clamp contacts the sheet of sterilization material rather than the container.
6. The sterilization packaging system of claim 1 , wherein the clamp is held in the clamped position by a latch, and wherein the latch is integrally formed with the clamp.
7. The sterilization packaging system of claim 6 , wherein the latch comprises a first arm defining a catch and a second arm defining a detent.
8. The sterilization packaging system of claim 7 , wherein the clamp comprises a hinge portion opposite the latch.
9. The sterilization packaging system of claim 8 , wherein one of the first arm or the second arm hinges about the hinge portion to place the clamp in the open position or the clamped position.
10. The sterilization packaging system of claim 1 , wherein the sheet of sterilization material is a breathable film.
11. The sterilization packaging system of claim 10 , wherein the breathable film is transparent.
12. The sterilization packaging system of claim 1 , wherein the clamp comprises a protrusion defined by a vertical portion of the clamp and the container defines a groove, wherein the protrusion of the clamp protrudes into the groove when the clamp is positioned on the container, and wherein the sheet of sterilization material extends between the clamp and the container such that the protrusion of the clamp contacts the sheet of sterilization material rather than the groove of the container.
13. A sealing assembly for a sterilization packaging system, the sealing assembly comprising:
a sheet of sterilization material; and
a clamp, the clamp having an open position and a clamped position, the clamp further having an L-shaped cross-section formed by a vertical portion including a planar surface and a horizontal portion including a planar surface,
wherein the clamp is configured to extend about a perimeter of a container for containing items to be sterilized,
wherein the clamp is held in the clamped position by a latch, and
wherein the latch comprises a catch defined by a first arm of the clamp and a detent defined by a second arm of the clamp such that the latch is integral with the clamp, the detent configured to fasten in the catch to hold the clamp in the clamped position.
14. The sealing assembly of claim 13 , wherein the clamp comprises a hinge portion opposite the latch, and wherein one of the first arm or the second arm hinge about the hinge portion to place the clamp in the open position or the clamped position.
15. The sealing assembly of claim 13 , wherein the sheet of sterilization material is configured to pass sterilant into the container and to retard transmission of contaminants into the container.
16. The sealing assembly of claim 13 , wherein the vertical portion extends along a vertical direction, the vertical portion positionable adjacent one or more vertical walls of the container and the horizontal portion extends perpendicular to the vertical portion, and wherein the horizontal portion defines a window.
17. The sealing assembly of claim 13 , wherein the sealing assembly is disposable.
18. A sealing assembly for a sterilization packaging system, the sealing assembly comprising:
a sheet of sterilization material; and
a clamp having an open position and a clamped position, the clamp including
a vertical portion extending along a vertical direction, and
a planar horizontal portion extending perpendicular to the vertical portion, the horizontal portion defining a window,
wherein the clamp held in the clamped position by a latch,
wherein the latch is integrally formed with the clamp and comprises a first arm defining a catch and a second arm defining a detent, and
wherein the sheet of sterilization material is visible through the window defined by the clamp when the clamp is in the clamped position.
19. The sealing assembly of claim 18 , wherein the sterilization packaging system comprises a container having a perimeter defining an opening through which the items to be sterilized are placed in the container, and wherein the horizontal portion of the clamp extends inward with respect to the perimeter of the container such that the horizontal portion is positioned over the opening.
20. The sealing assembly of claim 18 , wherein the clamp comprises a hinge portion opposite the latch.
