Patent number: 9579465Abstract: A simple method and device enabling a unit dose from a reservoir is provided. The dose is drawn into the reservoir and is then expelled from the device by depressing a plunger. The plunger has features which divide the dose into discrete intervals. As the plunger is moved during delivery, the features on the plunger and features connected to a barrel interact to provide for intermittent stops to the delivery. Other aspects of the device provide for reduced dead space, safety and selective interconnection with other devices. Thus, the device divides the dose.Type: GrantFiled: January 19, 2015Date of Patent: February 28, 2017Assignee: Becton, Dickinson and CompanyInventors: Bruno Baney, Colin May, Patrick Dupuis, Frederic Perot

Patent number: 8568358Abstract: The invention relates to a device (1) for delivering two predetermined doses of a product (3), comprising: —a container (2) for containing said product, said container having a distal end (2d) through which the product is delivered under the distal pressure of a piston, —a pusher (7) movable with respect to said container for causing said piston (4) to move in the distal direction from an initial position, in which none of said product has been expelled to a first position, in which a first dose of said product has been expelled, and to a second position, in which a second dose of said product has been expelled, —a holder body (15) receiving said container and said pusher (7), —biasing means (22) for urging said pusher (7) in the distal direction, from the initial to the first position, and to the second position, —first and second retaining means (9, 11, 19) for maintaining said pusher (7) in said initial position, and in said first position, —first and second actuation means (18) to deactivate said first anType: GrantFiled: November 15, 2007Date of Patent: October 29, 2013Assignee: Becton Dickinson FranceInventors: Guillaume Grunhut, Patrick Dupuis

The dose is drawn into the reservoir and is then expelled from the device by depressing the plunger. The plunger (30) has features which divide the dose into discrete intervals. As the plunger is moved during delivery, features on the plunger and features connected to the barrel interact to provide for intermittent stops to the injection process. Other aspects of the device provide-for reduced dead space, safety and selective interconnection with other devices. Thus, the delivery device divides the dose.Type: ApplicationFiled: January 30, 2008Publication date: May 19, 2011Inventors: Bruno Baney, Colin May, Patrick Dupuis, Frederic Perot

Patent number: 5064628Abstract: Provided is a ceric oxide having a specific surface of at least 85 m.sup.2 /g after calcination between 350.degree. and 550.degree. C., and being further characterized in that it has a pore volume of at least 0.15 cm.sup.3 /g and a median pore diameter greater than 50 .ANG.. The ceric oxide is prepared by destabilizing an aqueous colloidal dispersion of a cerium (IV) compound by the addition of base thereto, separating the precipitate which results and subjecting it to a heat treatment.Type: GrantFiled: February 22, 1990Date of Patent: November 12, 1991Assignee: Rhone-Poulenc ChimieInventors: Jean-Yves Chane-Ching, Jean-Luc Le Loarer, Patrick Dupuis
