Drug delivery device and method for decoupling a drug administration element and at least one part of a drug delivery device

A drug delivery device, comprising:

• a housing for receiving a drug reservoir,
• a drug administration element fluidically coupled to the drug reservoir, the drug administration element defining a drug outlet of the drug delivery device, and
• at least one supporting member coupled to the drug administration element for supporting the drug administration element relative to the housing,
• wherein the at least one supporting member is configured to allow a radial displacement of the housing relative to the drug administration element during a drug delivery operation comprising injection of a drug contained in the drug reservoir.

A method for decoupling a drug administration element and at least one part of a drug delivery device, the drug delivery comprising:

• a housing for receiving a drug reservoir,
• a drug administration element fluidically coupled to the drug reservoir, the drug administration element defining a drug outlet of the drug delivery device, and
• at least one supporting member coupled to the drug administration element for supporting the drug administration element relative to the housing,
• wherein the at least one supporting member is configured to allow a radial displacement of the housing relative to the drug administration element during a drug delivery operation comprising injection of a drug contained in the drug reservoir, the method comprising
• using the radial supporting member comprising at least one of at least one soft material for holding a drug reservoir or at least one flexible holding portion for holding the drug reservoir,
• wherein the at least one of the at least one soft material or the at least one flexible holding portion is configured to allow a relative radial displacement of at least a portion of the drug reservoir relative to a housing of the drug delivery device during insertion of a drug administration element arranged or arrangeable on the distal end of the drug reservoir into the tissue of a patient.

A drug delivery device comprising:

• a housing for receiving a drug reservoir,
• a drug administration element is fluidically coupled to the drug reservoir, the drug administration element defining a drug outlet of the drug delivery device, and
• at least one supporting member coupled to the drug administration element for supporting the drug administration element relative to the housing,
• wherein the at least one supporting member is configured to allow a radial displacement of the housing relative to the drug administration element during a drug delivery operation,
• wherein the at least one supporting member comprises a radial supporting member that is configured to support the drug reservoir radially during injection of a drug that is contained in the drug reservoir,
• wherein the radial supporting member comprises a soft material having a Shore A hardness value below 90, and wherein the soft material extends from an inner wall of the housing to the drug reservoir.
