Patent number: 8021345Abstract: The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose cartridge and permit a user to set the delivery dose. The injector may include a housing, a cartridge containing medicinal product, the cartridge being retained within the housing, means for selecting a dose of medicinal product to be expelled, and means for expelling the selected dose of medicinal product. The housing may be a unitary housing within which the means for selecting a dose and the means for expelling the selected dose are moveably retained. Alternatively, the injector may include a housing, a piston rod, an insert located in the housing and through which the piston may rotate, a ratchet, a dose dial sleeve, a drive sleeve, a button located on the drive sleeve and rotatable with respect to the drive sleeve, and a clutch which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.Type: GrantFiled: October 8, 2010Date of Patent: September 20, 2011Assignee: DCA Design International Ltd.Inventors: Robert Frederick Veasey, Christopher Nigel Langley, Steven Wimpenny

Patent number: 7985201Abstract: Injection devices are known for the self administration of a medicament by patients in which the medicament is contained within a cartridge located within the injection device. It is a problem that such injection devices should be small enough to fit into a jacket pocket or a hand bag without difficulty. Concurrently, the injection device must be of size that enables a piston or similar used to drive a cartridge bung within the cartridge to be moved both to a maximum dispense position within the cartridge and to be fully withdrawn from the cartridge to allow for replacement of the cartridge.Type: GrantFiled: March 26, 2002Date of Patent: July 26, 2011Assignee: DCA Design International LimitedInventors: Christopher Nigel Langley, Robert Woolston, David Aubrey Plumptre

Patent number: 7905867Abstract: A pen-type injector is improved so that a user may select a delivery dose of medicinal product from a multidose cartridge. The injector includes a housing. a cartridge containing medicinal product retained within a housing, a piston rod, a dose selecting member to select a dose of medicinal product to be expelled, and a drive member to expel the selected dose of medicinal product. The housing is formed unitary so that the dose selecting member and the drive member are moveably retained within the housing. The injector may include ratchet means associated with the insert to ensure the piston rod only rotates in a single direction through the insert, a button located on the drive sleeve, and clutch means which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.Type: GrantFiled: March 2, 2004Date of Patent: March 15, 2011Assignee: DCA Design International Ltd.Inventors: Robert Frederick Veasey, Christopher Nigel Langley, Steven Wimpenny

Patent number: 7846146Abstract: Many of those having diabetes take a combination of slow and fast acting types of insulin. It is important that the different forms of medicament do not become confused. To this end, a medicament cartridge is provided comprising a sleeve having a bottleneck providing a flange at a first end, a fluid impermeable membrane secured across the first end by a metal cap beaded beneath the flange, and a displaceable piston located internally of the sleeve towards a second end of the sleeve, a collar located against an external periphery of the cartridge housing beneath the flange and an adaptor top press fit over the cap and the collar, the adaptor top being provided with means to act upon the collar thereby to retain the adaptor top on the sleeve.Type: GrantFiled: March 17, 2008Date of Patent: December 7, 2010Assignee: DCA Design International LimitedInventors: Robert Woolston, Christopher Nigel Langley, Lee Simon Adams

Patent number: 7699815Abstract: A drive mechanism for an injection device is disclosed in which piston means are selectively driven to expel medicament from within a medicament cartridge. The drive mechanism comprises a drive means associated with a first ratchet member, a second ratchet member associated with the piston means, a housing, the first ratchet member and the second ratchet member being disposed within the housing. The second ratchet member being biased by biasing means toward the first ratchet member. The drive means is actuable reciprocally to drive the first ratchet member in a first angular direction such that the first ratchet member drives the second ratchet member along its longitudinal axis against the biasing means along at least a part of its movement and subsequently drives the first ratchet member and the second ratchet member together in a second angular direction thereby to drive the piston means.Type: GrantFiled: December 21, 2001Date of Patent: April 20, 2010Assignee: DCA Design International LimitedInventors: Christopher Nigel Langley, Shane Alistair Day, Robert Frederick Veasey, Robert Woolston

Patent number: 7695456Abstract: The present invention relates to a medicament delivery device such as a pen type injector used to expel medicament from a medicament cartridge under the action of a lead screw. The medicament cartridge typically comprises a cylinder having a displaceable piston at one end displacement causing medicament contained within the cartridge to be expelled. It is of advantage to know when the plunger contacts the displaceable piston since no delivery of medicament can occur before this point.Type: GrantFiled: January 22, 2003Date of Patent: April 13, 2010Assignee: DCA Design International LimitedInventors: Christopher Nigel Langley, Robert Frederick Veasey
