Patent number: 11918790Abstract: A drug injection device includes a last dose setting having a main drive pin, a drive wheel, a driven wheel, an abutment element fixedly coupled to, or integrally formed with, the driven wheel. The drive wheel has a rotation axis parallel to a longitudinal axis and is configured to be driven about the longitudinal axis by a knob and to be periodically driven in rotation about the rotation axis by the main drive pin, during a drug dose setting. The driven wheel has a second rotation axis parallel or coaxial to said longitudinal axis and is configured to be periodically driven about the longitudinal axis by the drive wheel. The abutment element is configured to prevent the rotation of the drive wheel about the longitudinal axis when the knob has made a predetermined number of full and/or partial rotations about the longitudinal axis correlated to the predetermined drug volume.Type: GrantFiled: December 21, 2022Date of Patent: March 5, 2024Assignee: Stevanato Group S.P.A.Inventors: Oliver Taylor Harvey, Christopher John Hurlstone, Isobel Rachel Sands, Rhona Ann Sinclair

Patent number: 9713679Abstract: Syringe for dispensing foam having a syringe barrel, a nozzle and a bore to receive a syringe plunger having a front end and a back end. The syringe plunger includes at the front end thereof a waste container defined by a cylindrical side wall, a front end wall and a rear end wall, the walls being arranged such that an external cylindrical surface of the walls forms a seal with an internal surface of the syringe barrel. The waste container has an inlet aperture in the front end wall which is in communication with the syringe nozzle when the plunger is fully depressed into the syringe barrel. The waste container further has a hydrophobic vent in the rear end wall thereof which allows air to escape from the waste container while substantially preventing foam from escaping the waste container when the syringe is in use.Type: GrantFiled: October 8, 2015Date of Patent: July 25, 2017Assignee: BTG INTERNATIONAL LIMITEDInventors: Stuart Brian William Kay, Christopher John Hurlstone, Julian Richard Dixon, Andrew Gordon Pocock

Publication number: 20160303328Abstract: Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.Type: ApplicationFiled: June 27, 2016Publication date: October 20, 2016Inventors: Stuart Brian William KAY, Christopher John HURLSTONE, Julian Richard DIXON, Andrew Gordon POCOCK

Publication number: 20120090608Abstract: A delivery device for and method of delivering substance, the delivery device comprising: a delivery outlet from which substance is in use delivered; a gas chamber containing a gas and being of reducible volume, wherein a reduction in the volume of the gas chamber to a predeterminable volume acts to pressurize the contained gas to a predeterminable pressure; a seal element disposed between the gas chamber and the delivery outlet; and an opening mechanism configured, on reduction of the volume of the gas chamber to a predeterminable volume, to open the seal element, whereupon a gas flow from the gas chamber acts to deliver substance from the delivery outlet.Type: ApplicationFiled: May 2, 2011Publication date: April 19, 2012Applicant: OptiNose ASInventors: Per Gisle Djupesland, Matthew Egerton Young, Andrew Robert Fry, Christopher John Hurlstone

Patent number: 8122917Abstract: A foam transfer device is described, for use with aerosol canister apparatus for producing a sclerosant foam for the treatment of, inter alia, varicose veins. The device enables diversion of an initial quantity of below-specification foam from the canister to waste, e.g. to an integral waste chamber, before dispensing a further quantity of foam for use in treatment. The switching of the flow from the waste chamber to a different outlet for use is accomplished without interrupting the flow from the aerosol canister since this would cause the foam to drop below specification again. The waste chamber may be transparent so that the foam entering it can be observed and a decision made by a user when to stop diverting foam to waste. Alternatively, the foam may be diverted automatically e.g. when a set time has elapsed or a set volume of foam dispensed. The foam for use is normally dispensed into a syringe for subsequent injection into a varicose vein of a patient.Type: GrantFiled: September 9, 2010Date of Patent: February 28, 2012Assignee: BTG International LimitedInventors: Anthony David Harman, David Dakin Iowerth Wright, Jam Wilem Marinus Mijers, Stuart Brian William Kay, Christopher John Hurlstone, Julina Richard Dixon, Andrew Gordon Pocock, Brendan Hogan

Publication number: 20120046609Abstract: An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation.Type: ApplicationFiled: October 31, 2011Publication date: February 23, 2012Applicant: Meridian Medical Technologies, Inc.Inventors: C.
