Title:
INJECTION DEVICE HAVING A SUSPENDED PARENTERAL INTERFACE
Document Type and Number:
WIPO Patent Application WO/2021/206902
Kind Code:
A3
Abstract:
Systems and methods for drug delivery are disclosed in which an injection device comprises a parenteral interface, comprising a support and a needle assembly, suspended within a cavity in a housing of the device such that the parenteral interface is movably mounted with respect to the housing when the needle assembly is in the injection position. The parenteral interface can be configured to allow movement of the housing of the device with respect to the skin without displacing the needle assembly. The devices can be configured to passively or actively compensate for movement of the housing relative to the injection site to ensure correct delivery depth is maintained during time device is worn. For example, by mounting the support of the parenteral interface on a deformable mount or an articulated or rotatable component.
