Publication number: 20180147352Abstract: The invention provides an injection device for delivering a dose of medicament from a syringe. The injection device comprises a housing (10), a plunger (110) moveably mounted within the housing, an actuation mechanism (120, 122) arranged to provide a forward biasing force to urge the plunger forward in use to express a dose of medicament and a trigger mechanism (40) arranged to (directly or indirectly) releaseably hold the plunger against the force of the actuation mechanism. The injection device further comprises a plunger velocity regulator comprising a cam surface (162) associated with one of the housing or the plunger, and a cam member (152) associated with the other of the plunger or the housing and arranged to engage the cam surface during actuation movement of the plunger such that axial movement of the plunger relative to the housing causes relative rotational movement of the cam member and limits the forward velocity of the plunger movement.Type: ApplicationFiled: May 20, 2016Publication date: May 31, 2018Inventors: Matthew Farmer, Oliver Gould

Publication number: 20180147353Abstract: Auto-injector for administering a dose of a liquid medicament includes a housing to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament (M), the housing having a distal end (D) and a proximal end (P) with an orifice to apply against an injection site. A spring means, upon activation, can push the needle from inside the housing through the orifice and past the proximal end (P), operate the syringe to supply the dose of medicament (M), and retract the syringe with the needle after delivering the medicament (M). An activating means can lock the spring means in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means for injection.Type: ApplicationFiled: January 25, 2018Publication date: May 31, 2018Inventors: Matthew Ekman, Yannick Hourmand, Timothy Donald Barrow-Williams

Publication number: 20180147354Abstract: The present disclosure relates to a portable pressure container for driving a medical device. The container includes a pressure housing confining an interior volume and a pressure outlet extending through the pressure housing. The interior volume comprises a liquid storage portion and a gas storage portion. The liquid storage portion and the gas storage portion are in flow connection with each other. The liquid storage portion is configured to store a liquid phase of a driving medium. The gas storage portion is configured to store a gas phase of the driving medium. The pressure outlet is only in flow connection with the gas storage portion.Type: ApplicationFiled: May 6, 2016Publication date: May 31, 2018Inventors: Christian Nessel, Christian Dexheimer, Tobias Uth, Florian Hammen

Publication number: 20180147355Abstract: The present disclosure relates to a syringe for mixing two substances which have been retained separately inside the syringe, for instance in a storage condition. In particular the present disclosure relates to a syringe for 1) retaining a dry composition in a vacuum, and 2) mixing the dry composition with an aqueous medium to form a flowable substance. One embodiment relates to a syringe for retaining and mixing first and second substances comprising: a barrel comprising a sealable and/or closable distal outlet and a vacuum chamber for holding a first substance, a plunger incorporating a reservoir chamber for holding a second substance and configured to be axially displaced through a proximal end of the barrel, a membrane separating the vacuum chamber and the reservoir chamber, and a pointed member, such as one or more needles, for penetrating the membrane.Type: ApplicationFiled: June 30, 2016Publication date: May 31, 2018Inventors: Kristian Larsen, Lise Sjørup Elle, Thomas Ingemann Jensen

Publication number: 20180147357Abstract: Carpule systems and methods of making and using the same are disclosed. In one embodiment, a carpule system includes a carpule having a carpule body that defines a first chamber and a second chamber. A divider can be disposed between the first and second chambers for isolating a first material in the first chamber from a second material in the second chamber. The carpule system may also include a carpule mixing device that displaces a portion of the divider for mixing the first and second materials to form a mixture and a carpule syringe that dispenses an amount of the mixture. The amount of the mixture being dispensed is measured via an audible sound and/or a tactile sensation provided by the carpule syringe. Systems and methods herein advantageously obviate the need for mixing powdered material via multiple syringes, reduce waste and cost, and improve the accuracy of administering pharmaceutical compositions.Type: ApplicationFiled: November 29, 2016Publication date: May 31, 2018Inventors: Amir Marashi, Jack Krajekian
