Membrane and a chamber of a drug delivery device |
| abstract |
A drug delivery device for delivery of a drug which comprises a mixture of a first substance and a second substance, the device including a first chamber (24) for housing the first substance, a second chamber (30) for housing the second substance and a membrane (28) which on application of a predetermined condition thereto is movable from a first disposition in which it partitions the first and second chambers to prevent mixture of the first and second substances to a second disposition in which it enables the first and second substances to be mixed. In one aspect, the membrane (28) contains a barrier material comprising polychlorotrifluoroethylene or a copolymer thereof, polyvinylidene chloride or a copolymer thereof or a silicon oxide. In another aspect, the first chamber (24) is formed from a polyethylene based polymer. |
