MICRONEEDLE ADAPTER FOR DOSED DRUG DELIVERY DEVICES

摘要

An adapter (50) for achieving intradennal 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 (22) for sliding a recess of the adapter onto a projection of the dosed drug delivery device and a hollow needle (25) deployed for piercing the septum. At least one microneedle (10) projects from the connector. A flow path arrangement (28) interconnects the needle and the hollow microneedle(s). The recess is shaped to restrict the microneedle(s) to only a finite 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.

1. An adapter for achieving intradermal dosed delivery of a liquid by use of a dosed drug delivery device, the dosed drug delivery device including a reservoir having a pierceable septum, the adapter comprising:
(a) a connector including:
(i) an attachment configuration for attachment to the dosed drug delivery device by sliding the adapter onto the dosed drug delivery device so that a recess of the adapter mates with a matching projection of the dosed drug delivery device, and(ii) a hollow needle deployed for piercing the septum; (b) at least one hollow microneedle projecting from said connector; and (c) a flow path arrangement interconnecting said needle and said at least one hollow microneedle;wherein said recess is shaped to restrict said at least one microneedle to one of a finite number of rotational orientations relative to an axis of the dosed drug delivery device when the adapter is attached to the dosed drug delivery device.
