  • Patent number: 5281391
    Abstract: A portable disinfecting and disposal device for medical waste. A disposal device includes a plastic container resistant to penetration, either from medical sharps inside or external effects. The device has a top and bottom portion with perimeter seal areas which upon closure prevent nondestructive reopening. The device top portion includes a chemically filled packet which is sealed during ongoing use for attachment of medical waste to the device but is unsealed by spikes for use after collection of the medical waste. The collected medical waste is accounted for by a system to identify the number and type of medical waste viewable through the plastic container after closing the device as well as when the device is open and being used.
