    摘要: The present disclosure provides an inner tubular body for a medicament delivery device. The inner tubular body extends along a longitudinal axis from a proximal end to a distal end. The inner tubular body includes a distal part and a proximal part. The distal part includes a flexible arm extending distally, the flexible arm comprises a first spring support at the distal end of the flexible arm and a plunger rod support at the distal end of the flexible arm. The first spring support is inclined in a radially inward direction and is configured to support a distal end of a drive spring of the medicament delivery device when the medicament delivery device is in a non-activated state. The distal part further includes a second spring support extending distally and being configured to support the distal end of the drive spring of the medicament delivery device when the medicament delivery device is in an activated state. The plunger rod support is configured to engage with a plunger rod of the medicament delivery device in order to inhibit a proximal movement of the plunger rod when the medicament delivery device is in the non-activated state. The first spring support is configured to interact with an activation button that is at a distal end of the medicament delivery device. Triggering of the activation button allows a radial outward deflection of the flexible arm thereby disengaging the plunger rod support from the plunger rod and disengaging the first spring support from the distal end of the drive spring.

    摘要: Some embodiments of a low profile intramuscular auto-injector optionally comprise a contact surface contoured to fit a body surface. Optionally a height of the injector is less than ¼ a perimeter of the contact surface. Optionally a cover protects said contact surface. Optionally the device includes a priming mechanism coupled to the cover wherein removal of the cover activates the priming mechanism for priming the injector and/or increasing a height of the injector. Optionally the injector includes a cylindrical pharmaceutical reservoir rigidly attached to an injection needle. Optionally in a compact storage state the injection needle is at a low angle to the contact surface. Optionally during priming the needle and/or reservoir rotate to orient the needle at a higher angle to the contact surface.

    摘要: A dispensing mechanism for delivering a dosage of medicament including a housing having a proximal-distal axis; a plunger rod having a screw thread and configured to advance along the proximal-distal axis relative to the housing; a user-operable push button moveable along the proximal-distal axis relative to the housing; a twist driver threadably engaged with the push button such that movement of the push button towards the distal end of the housing causes rotation of the twist driver about the proximal-distal axis; and a driver engaged with the twist driver such that rotation of the twist driver causes rotation of the driver, the driver also engaged with a portion of the plunger rod such that rotation of the driver causes rotation of the plunger rod, advancing the plunger rod along the proximal-distal axis relative to the housing.
