    摘要： A supplemental device for attachment to an injection device, the supplemental device comprising: an electromechanical switch arrangement having an open state and a closed state, the electromechanical switch arrangement comprising a protrusion configured to contact a surface of the injection device when a dose of zero units is dialled into the injection device, wherein the state of the switch arrangement is configured to change when a dose dialled into the attached injection device is decreased from one unit to zero units; and a processor arrangement configured to: detect one or more changes in the state of the electromechanical switch arrangement; and determine from the one or more state changes that a dose of zero units is dialled into the injection device.

    摘要： The present invention concerns a mechanism for a drug delivery device, having a longitudinal axis and comprising a first member comprising a first contact surface and a second member comprising a second contact surface, wherein the first member is configured to be assembled to the second member, wherein the first member and the second member are configured such that the first contact surface abuts the second contact surface when the first member is assembled to the second member, wherein the first contact surface is arranged such that a force applied to the mechanism in a direction parallel to the longitudinal axis is split up into a first component in a direction perpendicular to a surface normal of the first contact surface and a second component parallel to the surface normal, wherein the first member and the second member are configured such that the first member is detached from the second member by the force applied to the mechanism in a direction parallel to the longitudinal axis if the absolute value of the force is stronger than a first predetermined value, and wherein the first predetermined value is defined as the absolute value of the force which has a first component strong enough to move the first contact surface out of abutment with the second member.

    摘要： The present invention relates to a drive mechanism which is suitable for an injection device, especially a pen type drug delivery device. The mechanism includes a housing, a dosing member which during dose setting, dose resetting and dose dispensing rotates relative to the housing between a zero dose position and a maximum dose position, and an insert that is rotationally constrained to the housing. The dosing member and the insert each include at least one abutment feature contacting each other when the dosing member reaches its zero dose position during dose dispensing, and an audible and/or tactile feedback is generated by the contact of the abutment features.

    摘要： The piston rod arrangement is in an assembled state before use and comprises a piston rod, a bung, which is intended to be driven by the piston rod, a body member, and a drive member. The piston rod is threadedly engaged with the body member, and the drive member is threadedly engaged with the piston rod and movable relative to the body member. A mechanism is provided defining unit steps of movement of the drive member and corresponding unit steps of movement of the piston rod. The piston rod is arranged in contact with the bung or at a distance from the bung that is less than a distance of one corresponding unit step of movement. When the piston rod, the bung and the drive member are assembled in the body member, the piston rod is advanced with respect to the body member towards the bung, until the piston rod is stopped by the bung. The drive member is rotated until the piston rod begins to advance again and the drive member is then stopped, and the piston rod is fixed at or near the position obtained.
