Product packaging
A product allows gaseous manufacturing by-products to be vented from the inside a sealed package tray. An exemplary method for packaging a device includes sealing the device inside a package tray with a gas-permeable sealing material, resulting in a sealed package tray. The sealing material allows volatile substances to vent from inside the sealed package tray to outside the sealed package tray.
1. A method for packaging a device, the method comprising:
placing the device directly on a package tray;
providing a cover having a periphery, wherein the cover is formed from a gas-permeable material at least along the periphery;
sealing the device inside the package tray with the cover, resulting in a sealed package tray, wherein the gas-permeable material along the periphery of the cover is directly sealed to the package tray and wherein the gas-permeable material of the cover allows volatile substances to vent from the device inside the sealed package tray to outside the sealed package tray;
sterilizing the device after sealing the device inside the package tray, wherein sterilizing the device comprises radiating the sealed package tray with sterilizing energy.
2. The method of claim 1 , wherein:
the device comprises glucose oxidase enzyme; and
the gas-permeable material vents volatile substances that would otherwise degrade the glucose oxidase enzyme.
3. The method of claim 1 , wherein:
the device comprises an electrochemical sensor with glucose oxidase enzyme; and
the gas-permeable material vents volatile substances that would otherwise degrade the glucose oxidase enzyme.
4. The method of claim 3 , wherein:
the device comprises a sensor mounting pedestal for the electrochemical sensor, the sensor mounting pedestal formed at least in part from a plastic material; and
the gas-permeable material vents volatile substances outgassed from the plastic material.
5. The method of claim 3 , wherein:
the device comprises a sensor introducer for the electrochemical sensor, the sensor introducer formed at least in part from a plastic material; and
the gas-permeable material vents volatile substances outgassed from the plastic material.
6. The method of claim 1 , wherein:
the package tray is formed at least in part from a plastic material; and
the gas-permeable material vents volatile substances outgassed from the plastic material.
7. The method of claim 1 , wherein the gas-permeable material is composed of high-density polyethylene that forms a microbial barrier for the device.
8. The method of claim 1 , wherein the cover includes a central region surrounded by the periphery, and wherein the central region of the cover is formed from the gas-permeable material.
9. The method of claim 1 , wherein the package tray includes a sealing surface surrounding an opening, and wherein sealing the device inside the package tray with the cover comprises covering the opening with a microbial barrier material and forming a seal between the microbial barrier material and the sealing surface.
10. The method of claim 9 , further comprising sterilizing the device after sealing the device inside the package tray, wherein the microbial barrier material maintains sterility of the device while allowing volatile substances to vent from inside the sealed package tray to outside the sealed package tray.
11. A method for packaging a device, the method comprising:
placing the device in a package tray, wherein the package tray defines an opening;
sealing the device inside the package tray with a cover consisting of a gas-permeable sealing material, resulting in a sealed package tray, wherein the
cover completely covers the opening; and
venting volatile substances from the device inside the sealed package tray to outside the sealed package tray;
sterilizing the device after sealing the device inside the package tray, wherein sterilizing the device comprises radiating the sealed package tray with sterilizing energy.
12. The method of claim 11 , wherein:
the device comprises a glucose oxidase enzyme; and
the volatile substances would degrade the glucose oxidase enzyme if not vented.
13. The method of claim 12 , wherein:
the device comprises a plastic material; and
the volatile substances are outgassed from the plastic material.
14. The method of claim 11 , wherein the sealing material is high-density polyethylene that forms a microbial barrier for the device.
15. The method of claim 11 , further comprising sterilizing the device.
16. A product comprising:
a package tray;
a device comprising glucose oxidase enzyme in the package tray;
a cover formed from a gas-permeable sealing material having an inner surface and an outer surface, wherein the inner surface of the cover is directly coupled to the package tray at a sealing perimeter of the cover to form a sealed package tray, wherein the cover includes no holes from the inner surface to the outer surface within the sealing perimeter, and wherein no barrier is located between the device and the cover such that the gas-permeable sealing material of the cover allows volatile substances to vent from the glucose oxidase enzyme inside the sealed package tray to outside the sealed package tray; and
where in the device is sterilized after being sealed inside the package tray, wherein sterilizing the device comprises radiating the sealed package tray with sterilizing energy.
