Publication number: 20230113993Abstract: The invention provides a syringe for use in an ophthalmic injection. The syringe comprises a body, a stopper and a plunger. The body comprises an outlet at an outlet end and the stopper is arranged within the body such that a front surface of the stopper and the body define a variable volume chamber from which a fluid can be expelled though the outlet. The plunger comprises a plunger contact surface at a first end and a rod extends between the plunger contact surface and a rear portion. The plunger contact surface is arranged to contact the stopper but not couple thereto, such that the plunger can be used to force the stopper towards the outlet end of the body, reducing the volume of the variable volume chamber, but not to move the stopper away from the outlet end.Type: ApplicationFiled: December 9, 2022Publication date: April 13, 2023Inventors: Andrew BRYANT, Heinrich BUETTGEN, Wolfgang Papst, Marie Picci

Patent number: 6887432Abstract: An integrally built, linear array of cuvettes is made of a plastic material. Every cuvette of the array has the same shape and dimensions. Neighboring cuvettes are connected to each other by a single web. Each of the single webs has a curved shape and each cuvette has means forming integral part thereof and serving for accurately positioning the cuvette into an opening of a cuvette holder and means for removably connecting the cuvette to the cuvette holder. Each cuvette has an upper chamber and a lower chamber having a common symmetry axis passing through the centers of both chambers. Each of the upper and lower chambers has a substantially cylindrical shape. The cross-section of the upper chamber at the central part thereof is larger than the cross-section of the lower chamber. The lower chamber has an open lower end. The upper chamber has an open top end and an annular bottom wall having a central circular opening which connects the upper chamber with the lower chamber.Type: GrantFiled: February 15, 2002Date of Patent: May 3, 2005Assignees: Hoffmann-La Roche Inc., Weidmann Plastics Technology AGInventors: Manfred Kansy, Hansjörg Tschirky, Werner Schneider, Heinrich Büttgen, Tilo Callenbach, Karl Mazenauer
