Abstract: A medicament delivery device for dispensing discrete doses of medicament comprises: first and second medicament carriers each comprising said doses of medicament contained in a plurality of individual compartments spaced along a carrier strip and sealed by a sealing layer; first and second opening mechanisms each arranged to handle a respective one of the first and second medicament carriers and to open each compartment of the respective medicament carrier by separating the sealing layer from the carrier strip as the medicament carrier is advanced through the device; a take-up spool arranged to wind the separated sealing layers thereon such as to maintain the separated sealing layers in tension, each separated sealing layer having a path of travel between a respective one of the first and second opening mechanisms and the take-up spool; and a tension control element in contact with each of the separated sealing layers, wherein at least a part of the tension control element is arranged to be movable by a biasing force, which is exerted on the tension control element by the separated sealing layers as a result of any inequality in the tensions of the separated sealing layers wound by the take-up spool, to alter the length of the path of travel of each separated sealing layer so as to substantially equalise the tensions in the separated sealing layers.

Abstract: A manifold for a medicament delivery device configured to deliver discrete doses of medicament contained in a plurality of individual compartments spaced along a carrier strip and sealed by a sealing layer to form a medicament carrier, the manifold comprising: at least one opening mechanism comprising a release member arranged to engage between the carrier strip and the sealing layer of a medicament carrier so as to separate the sealing layer from the carrier strip and thereby open a compartment of the medicament carrier as it is advanced into an entrainment position; wherein the release member includes a surface configured to cover the opened compartment when in the entrainment position so as substantially to contain the medicament dose of said opened compartment.

Abstract: A device for releasing discrete doses of medicament carried in a plurality of spaced-apart compartments on a medicament carrier, each compartment being arranged in a carrier strip and sealed by a sealing layer, the device comprising: a release mechanism arranged to engage between the carrier strip and the sealing layer so as to unseal at least a portion of the compartment and expose the medicament dose contained therein, wherein the release mechanism preferably covers said exposed compartment in place of the sealing layer.
