US Patent 10463572 Device for subcutaneous delivery of fluid medicament

The application is directed to a vial adapter for attaching a medicament vial to a medicament delivery device having a reservoir adapted to receive and contain the medicament. The vial adapter can include a housing with two ports (one for attaching the reservoir and the other for attaching to the vial), a hollow needle that pierces septums sealing each of the reservoir and the vial, and a floating part that fixedly holds the hollow needle. Clearance between the floating part and the housing can enable relative movement of the floating part.
