Patent CA-2162697-C (CA)
Title: An endoscope cleaner/sterilizer
Inventor: LANGFORD TERRENCE R
IPC: A61L11/00
Filed: 1994-05-12
Granted: 1999-07-20
Abstract: A cleansing/sterilizing apparatus which is a transportable apparatus (181) and method for inside-outside washing and sterilization of various complex reusable medical/dental instruments, including but not limited to Laparoscopic instruments and dental Handpieces. Agitation within the apparatus is by means of a peristaltic pump (185). The pumping function is accomplished by means of a pre-sterilized, compressible, disposable diaphragm that the operator places within the capsule (194) somewhere between the open ends of the laparoscopic instruments on the rack. The action of the pump (185) and the diaphragm forces oscillating surges of cleansing/sterilizing agent through the insides and over the outside of the laparoscopic instruments contained in the wash chamber. The apparatus avoids the use of heat, pressure, severe agitation, or corrosive chemicals which might damage delicate equipment. The apparatus preserves each processed instrument hermetically sealed in a sterile dry environment within a detachable/portable capsule (194) until its next use.

Abstract: A system (10) for mixing cementatious material, liquid and aggregate to form concrete includes a cementatious material measuring device (12) which provides dry cementatious material to an enclosed screw conveyor assembly (14). The dry cementatious material is thoroughly mixed with a liquid (68) within the screw conveyor (14) to form a flowable slurry without producing external cement dust pollution. The slurry is output by the screw conveyor (14) into a final product mixing chamber (16) where the flowable slurry is mixed together with aggregate to form concrete. The screw conveyor assembly (14) has an in-line input (20) and output (22), and space-saving diverging/converging conveyor sections (28, 56) to facilitate the retrofitting of existing concrete mixing plants. The conveyor assembly (14) includes a cement metering function as well as a slurry mixing function. A selectively openable and closable bypass gate (90) permits the dry cementatious material to be sent directly to the final product mixing chamber (16) in the event of conveyor failure.

Abstract: A single-piece piston used in a pneumatically-activated pump for metering predetermined amounts of liquids. The piston includes a head portion and a circumferentially-disposed channel for containing a sealing member. The stem section includes a longitudinally-disposed channel in fluid-flow connection with the channel. The piston is disposed within the pump body chamber. Lateral movement of the piston causes the sealing member to shift and block and unblock the end of the longitudinal channel allowing liquid to flow into a slot and to a pump chamber adjacent to the piston's head. The piston operates in association with an assembly for regulating the amount of liquid metered by the pump, a valve assembly for evacuating the liquid from the pump chamber into an outlet fitting, and a mechanism for regulating the flow of air into the outlet fitting to atomize the liquid. The piston operation can be calibrated for precise liquid metering.

Abstract: The cup carrier of this invention comprises a sheet of flat flexible material which forms at least one cup receiving opening and a handle. Each cup receiving opening is surrounded by a cup engaging portion that engages a tapered sidewall of a cup when the cup is inserted within the cup receiving opening. The cup engaging portion of the sheet forms an inner ring and an outer ring and bands connect the inner ring to the outer ring. A generally radial slit is positioned, preferably at an approximate midpoint, between two adjacent bands. The cup carrier permits a user to insert cups having a range of diameters into the cup receiving openings. A user can insert a small cup within the cup receiving opening and engage a sidewall of the small cup with the inner ring of the cup engaging portion. A user may alternatively insert a large cup within the cup receiving opening after breaking the inner ring along each of the generally radial slits, and engage a sidewall of the large cup with the outer ring of the cup engaging portion.
