Medicament container

摘要

The apparatus relates to a medicament container for a liquid medicament. The medicament container comprises a deformable bag with an outlet and at least one deformation member consisting of a shape memory alloy. The at least one deformation member is arranged to deform the deformable bag when the shape memory alloy passes from a first phase into a second phase by a phase transition, thereby changing the shape of the deformation member and squeezing a dose of the medicament through the outlet out of the bag.

1. A medicament container for a liquid medicament, the medicament container comprising:
a deformable bag with an outlet and a plurality of deformation members consisting of a shape memory alloy and arranged to deform the deformable bag when the shape memory alloy passes from a first phase into a second phase by a phase transition, thereby changing the shape of the deformation member and squeezing a dose of the medicament through the outlet out of the bag, wherein the plurality of deformation members are arranged consecutively along the deformable bag; and temperature regulation means for changing the temperature of a deformation member to cause the phase transition of its shape memory alloy, wherein the temperature regulation means comprise electrical connections for each deformation member for connecting the plurality of deformation members to an electrical power supply.
