Medicament delivery member modules

A medicament delivery member module (10) for a medicament delivery device, the medicament delivery member module (10) comprising a proximal shield (30), a distal shield (50) and a medicament delivery member hub (70), the medicament delivery member module (10) extending along a longitudinal axis (12) in an axial direction (13) from a proximal end (14) to a distal end (15),

• wherein the proximal shield (30) comprises a first surface (31) facing towards the longitudinal axis (12) and a second surface (32) facing away from the longitudinal axis (12),
• wherein the medicament delivery member hub (70) comprises a third surface (73) facing away from the longitudinal axis (12) and the distal shield (50) comprises a fourth surface (54) facing towards the longitudinal axis,
• wherein the proximal shield (30) is moveable in the axial direction (13) relative to the distal shield (50) from a proximal position to a distal position,
• wherein the medicament delivery member module (10) is arranged so that in a first part of a movement of the proximal shield (30) from the proximal position to the distal position,
• the first surface (31) and the third surface (73) are in contact with one another and the second surface (32) and the fourth surface (54) are in contact with one another, and the friction between the first surface (31) and the third surface (73) is greater than the friction between the second surface (32) and the fourth surface (54),
• so that during the first part of the movement of the proximal shield (30) from the proximal position to the distal position, the medicament delivery member hub (70) moves with the proximal shield (30),
• wherein the medicament delivery member module (10) is arranged so that in a subsequent part of the movement of the proximal shield (30) from the proximal position to the distal position,
• the first surface (31) and the third surface (73) are in contact with one another and the second surface (32) and the fourth surface (54) are spaced apart from one another, and
• the medicament delivery member hub (70) is restricted from further movement in the distal direction,
• so that the proximal shield (30) moves in the distal direction relative to both the distal shield (50) and the medicament delivery member hub (70) during the subsequent part of the movement of the proximal shield (30) from the proximal position to the distal position.
