A first valve portion is connected to the valve housing structure, wherein the first valve portion has a sealing edge. A second valve portion is positioned at least partially within the valve housing structure. A constrictable membrane has a pressurizable interior compartment, wherein the constrictable membrane supported by the second valve portion and positioned proximate to the first valve portion, wherein at least a portion of the constrictable membrane is movable to engageable with the sealing edge of the first valve portion.
1. A valve apparatus comprising:
a valve housing structure;
a first valve portion connected to the valve housing structure, wherein the first valve portion has a sealing edge;
a second valve portion positioned at least partially within the valve housing structure, wherein the second valve portion further comprises an upper valve part and a lower valve part having a gap positioned between the upper and lower valve parts; and
a constrictable membrane having a pressurizable interior compartment, the constrictable membrane supported by the second valve portion and positioned proximate to the first valve portion, wherein at least a portion of the constrictable membrane is movable to be engageable with the sealing edge of the first valve portion, wherein the constrictable membrane is affixed between the upper and lower valve parts and across the gap, wherein the sealing edge of the first valve portion is positioned within the gap formed between the upper and lower valve parts, wherein the constrictable membrane is movable between at least a first position where the constrictable membrane engages the sealing edge of the first valve portion to create a seal, and a second position where the constrictable membrane does not contact the sealing edge of the first valve portion.
2. The valve apparatus of claim 1 , wherein the valve housing structure is positioned within at least one of a top, a base, and a sidewall of a medical instrument sterilization container.
3. The valve apparatus of claim 1 , wherein at least a portion of the constrictable membrane is movable between at least a first position where the constrictable membrane engages the sealing edge of the first valve portion to create a seal, and a second position where the constrictable membrane does not contact the sealing edge of the first valve portion.
4. The valve apparatus of claim 3 , wherein when the constrictable membrane is in the first position, movement of a gaseous material through the valve housing structure is restricted.
5. The valve apparatus of claim 3 , wherein the second position of the constrictable membrane corresponds to at least one of a high heat and a high pressure condition within a sterilization environment, relative to an ambient heat and an ambient pressure.
6. The valve apparatus of claim 1 , wherein the constrictable membrane is stretched over an exterior surface of the second valve portion.
7. The valve apparatus of claim 1 , wherein the second valve portion is positioned within the valve housing structure with a threaded fastener.
8. The valve apparatus of claim 1 , wherein the upper valve part and the lower valve part are affixed to the valve housing with a threaded fastener.
9. The valve apparatus of claim 1 , wherein the sealing edge of the first valve portion is circumferentially positioned about the constrictable membrane.
10. The valve apparatus of claim 1 , wherein the constrictable membrane is one of a sphere and a spheroid.
11. A system for sterilizing medical instruments comprising:
a sterilization container having a plurality of walls, a base, and a top, wherein at least a portion of the plurality of walls, the base, and the top substantially enclose an interior area of the sterilization container;
a valve housing structure positioned within at least one of the plurality of walls, the base, and the top;
a first valve portion connected to the valve housing structure, wherein the first valve portion has a sealing edge;
a second valve portion positioned at least partially within the valve housing structure, wherein the second valve portion further comprises an upper valve part and a lower valve part having a gap positioned between the upper and lower valve parts; and
a constrictable membrane having a pressurizable interior compartment, the constrictable membrane supported by the second valve portion and positioned proximate to the first valve portion, wherein the constrictable membrane is affixed between the upper and lower valve parts and across the gap, wherein the sealing edge of the first valve portion is positioned within the gap formed between the upper and lower valve parts, wherein the constrictable membrane is movable between at least a first position where the constrictable membrane engages the sealing edge of the first valve portion to create a seal, and a second position where the constrictable membrane does not contact the sealing edge of the first valve portion.
12. The system for sterilizing medical instruments of claim 11 , wherein in the first position where the constrictable membrane engages the sealing edge of the first valve portion to seal an interior area of the sterilization container from an exterior atmosphere, and in the second position the constrictable membrane does not contact the sealing edge of the first valve portion to provide a pathway through the valve housing structure between the interior area of the sterilization container and the exterior atmosphere.
