Patent CA-2318834-A1 (CA)
Inventor: GREENBERG ROBERT S
IPC: A61B1/267
Filed: 1999-01-26
Abstract: The disclosed method uses a cuffed oro-pharyngeal airway (COPA) (10) as an adjunct for fiberoptic endotracheal intubation. This allows control, and support of the airway during the procedure. The disclosed techniques take advantage of the upper airway distending effects of the COPA cuff (14) and ability for continuous ventilation. In fact, using the COPA cuff (14) appropriately with the fiberoptic scope (50) outside it, it is possible to have the cuff augment the size of the hypopharynx, lift the epiglottis, and facilitate fiberoptic intubation. The ability to perform fiberoptic endotracheal intubation while effectively supporting the airway using the COPA (10) may be advantageous in managing the difficult airway and in teaching the technique of fiberoptic endotracheal intubation.

Patent CA-2322202-A1 (CA)
Inventor: ANDERSON NORMAN G
IPC: C12M1/34
Filed: 1999-03-09
Abstract: A method for separating microorganisms, especially infectious agents, from a mixture by two-dimensional centrifugation on the basis of sedimentation rate and isopycnic banding density, for sedimenting such microorganisms through zones of immobilized reagents to which they are resistant, for detecting banded particles by light scatter or fluorescence using nucleic acid specific dyes, and for recovering the banded particles in very small volumes for characterization by mass spectrometry of viral protein subunits and intact viral particles, and by fluorescence flow cytometric determination of both nucleic acid mass and the masses of fragments produced by restriction enzymes. The method is based on the discovery that individual microorganisms, such as bacterial and viral species, are each physically relatively homogeneous, and are distinguishable in their biophysical properties from other biological particles, and from non-biological particles found in nature. The method is useful for distinguishing infections, for identifying known microorganisms, and for discovering and characterizing new microorganisms. The method provides very rapid identification of microorganisms, and hence allows a rational choice of therapy for identified infectious agents. A particularly useful application is in clinical trials of new antibiotics and antivirals, where it is essential to identify at the outset individuals infected with the targeted infectious agent.

Patent CA-2344752-A1 (CA)
Title: Improved method and apparatus for locking charges into a charge holder
Inventor: GLENN CORBIN
IPC: E21B43/117
Filed: 2001-04-24
Abstract: The invention uses a pair of opposed tabs on the charge holder to engage a groove in the case of the shape charge. The case is generally conical in shape. However, the front opening of the case has both a first and second circumferential ridge separated by a groove. The diameter of the groove generally matches the distance between tabs. The second ridge can have a flat milled thereon to allow case to be inserted until the tabs contact the forward or first ridge. This locates the tabs between the first and second ridges and over the groove. The case is then rotated so that the tabs are captured between the two ridges. Once installed, the detonation cord is attached to the case. The cord helps prevent any rotation of the case, thereby securing it into the charge holder. Thus, the use of easily milled tabs on the charge holder in conjunction with an easily milled groove and flats on the case provide an improved apparatus and method for securing the shape charge into the charge holder of a perforation gun. When the charges are all installed, and the detonation cord is properly linked between each charge, then the charge holder can be placed in a carrier.

Title: Hygienic bottle cap and method for using same
Inventor: DUSHMAN LAWRENCE M
IPC: B67D3/00
Filed: 1999-10-20
Abstract: A cap includes a frangible path defining a flap to be formed when the frangible path is broken in response to a blunt probe penetrating the cap. Advantageously, the frangible path may be disposed substantially in a first plane which may be both (1) parallel to a second plane in which an opening o f the bottle (to which the cap is attached) is disposed, and (2) substantially  perpendicular to the direction in which the bottle is moved to cause the pro be to penetrate the cap. The frangible path may be defined in the first plane s o that a hinge portion of the flap remains connected to the cap after the prob e has been inserted therein. When the probe is later removed from the cap, the  flap may be caused to close so that water remaining in the water bottle is inhibited from exiting the water bottle. The hinge portion of the flap may b e made of a material having a shape memory sufficient to bias the flap at leas t slightly toward the closed position but that is flexible enough that the wat er pressure of the water remaining in the bottle has a substantial effect in further biasing the flap toward the closed position.
