  • Patent number: 5914047
    Abstract: A biohazardous liquid medical waste collection and treatment system provides on-site collection and treatment of surgical fluids. The system is mobile, and includes an upper unit and one or more lower units that are detachable from the upper unit. The upper unit includes a liquid disinfectant reservoir, liquid pump valves, and an electronic control unit which controls the operation of the pump valves. A disposable suction canister is mounted to the upper unit and collects liquid medical waste aspirated from a patient. A disposable tube set, including a motionless mixer, is connected to the disposable suction canister and the liquid disinfectant reservoir. Electronically controlled pumps (preferably peristaltic pumps) pump liquid waste from the suction canister along with the metered amount of liquid disinfectant from the liquid disinfectant reservoir through the motionless mixer and into a temporary storage receptacle on the lower unit.

  • Patent number: 4961502
    Abstract: An X-ray cassette holding which is capable of being sterilized for use in an Operating Room includes a hinged cover and an opening for receiving a non-sterile X-ray cassette. A receiver portion into which the cassette is inserted is spaced from the interior of the side and end walls of a pivoting cover to isolate the exterior of the cassette holder from contamination by virtue of the insertion of a contaminated cassette into the holder. Seals may be provided to seal the cover edges and portions of the receiver edges from the exterior of the holder when the cover is in a closed position. When the cover is opened, the cassette may be removed, and a new cassette inserted without contaminating the exterior sterile surfaces of the holder.
