MICRONEEDLE ADAPTER FOR DOSED DRUG DELIVERY DEVICES

摘要

An adapter for achieving intradermal dosed delivery of a liquid by use of a dosed drug delivery device including a reservoir having a pierceable septum, the adapter having a connector including an attachment configuration for sliding a recess of the adapter onto a projection of the dosed drug delivery device and a hollow needle deployed for piercing the septum. At least one microneedle projects from the connector. A flow path arrangement interconnects the needle and the hollow microneedle(s). The recess is shaped to restrict the rnicroneedle(s) to only a fmite number of rotational orientations relative to the axis of the device. The connector and/or the needle is adapted for application of a sealant to prevent leakage of the liquid.
