Abstract

A system and method of sterilization for medical instruments within a hydrogen peroxide sterilization process is provided. A medical instrument is housed in a sterilization tray, wherein the sterilization tray is formed from polypropylene and a glass material. The medical instrument and sterilization tray are subjected to a hydrogen peroxide sterilant.

Claims (10)

1. A method of manufacturing and using a sterilization tray comprising:

combining a quantity of polypropylene with a glass material comprising glass spheres and glass fibers;

injecting the combined quantity of polypropylene with glass material into a sheet form;

premixing the polypropylene and the glass material into a resin without the addition of copolymers prior to the injection molding;

thermoforming the sheet form of the combined quantity of polypropylene with glass material into a tray form, wherein the tray form defines at least one recess for housing at least one medical instrument for sterilization, thereby providing a sterilization tray; and

subjecting the sterilization tray to a hydrogen peroxide sterilant.

2. The method of claim 1 , wherein the sterilization tray includes up to 30% glass material.

3. The method of claim 1 , further comprising:

subjecting the medical instrument and sterilization tray to a steam sterilization.

4. The method of claim 1 , further comprising the step of subjecting the sterilization tray to an ethylene oxide sterilant.
