The present invention relates to a prefillable drug delivery device (1), comprising : - a housing (10) receiving a needle hub (20) movable with respect to said needle hub between a retracted position and a protection position, - a tubular barrel (30) intended to receive a drug, and pre-mountable on said housing so that said needle hub closes its distal end,
said device further comprising sealing means (22, 31) actionable once said tubular barrel is pre-assembled on said housing, capable of going from an inactive state where no sealing contact is present between said needle hub and said tubular barrel, to an active state, in which sealing contact is performed, wherein, in the active state of said sealing means, said tubular barrel is movable in translation with respect to said needle hub between a proximal position and a distal position, for realizing delivery of the drug.

A safety device 20 for shielding a medical needle 25 comprises a needle mount 28 supporting a medical needle and a needle shielding sleeve 34 arranged coaxially with the mount for sliding movement from an initial needle shielding position to a non-shielding position whereat at least the tip of the needle is exposed beyond the sleeve. Either the sleeve 34 or the mount 28 has both an abutment surface 31 and a sliding surface 29. A flexible connection mounts a radially deformable resilient finger 37 on the other of the sleeve and mount so that a first finger part 46 is configured for radial alignment with the abutment surface 31 where the finger blocks movement of the sleeve or for radial alignment with the sliding surface. A control member 40 is slidable coaxially with the sleeve and is co-operable with a second finger part 47 to the other side of said flexible connection. The control member 40 has a set position at which the first finger part is in radial alignment with the sliding surface so allowing movement of the sleeve from its initial shielding position towards its non-shielding position. This causes deformation of the finger which urges the sleeve back to a shielding position. The movement of the sleeve also causes the control member to be displaced from the set position. This movement of the control member 40 drives the second finger part outwardly which urges the first finger part inwardly and so into radial alignment with the abutment surface following the return of the sleeve to a shielding position. Subsequent movement of the sleeve is blocked by the finger engaging the abutment surface.

According to the invention, a safety device for a pre-filled syringe comprises of a needle shield adapted to cover an injection needle of the pre-filled syringe before and after an injection, a support body with at least one pivoting arm adapted to engage a barrel collar of the pre-filled syringe and an outer body with a first inner sleeve comprising a bevelled section. The needle shield, the support body and the outer body are telescopically arranged. The needle shield, the support body and the outer body may telescope with respect to each other to cover and to expose the injection needle of the pre-filled syringe. The bevelled section is arranged to abut against the pivoting arm connected to the support body by a living hinge to deflect the pivoting arm radially inwards, so that the pivoting arm may engage the barrel collar after a dose of a medicament contained in the pre-filled syringe has been disposed beneath the skin of a patient receiving the injection.

A drug delivery system to deliver two or more medicaments operable through a auto-injector drug delivery device and a single dispense interface. The device comprises a housing defining a primary reservoir containing a first medicament. A dosing mechanism operably connected to the primary reservoir. A single dispense interface is configured for fluid communication with the primary reservoir and a secondary reservoir of medicament containing at least one drug agent configured for fluid communication to the single dispense interface. A single activation of the dosing mechanism causes medicament from the primary reservoir and a non-user settable dose of the second medicament to be expelled through the single dispense interface.

Disclosed herein are various examples of a drug delivery system and corresponding method for delivering three or more medicaments. The system includes two major components: an auto-injector device that contains at least two medicaments and a medicated module that contains at least one medicament. The medicated module interfaces with the auto-injector device such that a combination dose comprising all of the medicaments can be delivered via a single dispense interface of the medicated module. In order to deliver a pre-defined combination dose, a user need only set the dose of one of the medicaments contained in the auto-injector device and need only activate the system once by actuating a dose delivery button on the auto-injector device.

A medicated module (260) attachable to a drug delivery device. The medicated module comprises a housing configured for attachment to a drug delivery device. The drug delivery device comprises a first medicament. A movable reservoir (250) is contained within the housing. A pre-determined volume of a second medicament is contained within the reservoir. An injection needle (230) is configured within the housing and the needle arrangement is arranged in fluid communication with the movable reservoir. A spring (210) can drive a piston (270) of the movable reservoir (250) to dispense the drugs.

The invention relates to an auto-injector (1) for administering a dose of a liquid medicament (M), comprising: - an elongate housing (2) arranged to contain a syringe (7), wherein the syringe (7) is slidably arranged with respect to the housing (2), - spring means (14) capable of, upon activation, pushing the needle (9) from a covered position inside the housing (2) into an advanced position through the orifice and past the proximal end (P) as well as operating the syringe (7) to supply the dose of medicament (M), - activating means (4) arranged to lock the spring means (14). The spring means (14) is a torsion spring (14). The activating means (4) is a trigger button (4), arranged at a distal end (D) of the housing (2) and operable by being pressed in proximal direction (P).
摘要:
A safety shield apparatus including a safety shield and mounting structure for mounting the safety shield to a medical needle. The safety shield includes a distal segment, a proximal segment and a retention member. The distal segment is pivotally secured to the proximal segment and the proximal segment is pivotally secured to the retention member. The retention member includes an opening for receiving a nose of a medical needle device, e.g., a blood collection device. In one embodiment, a retaining collar is provided which is dimensioned to be press-fit about the nose of the medical needle device to secure the safety shield to the medical needle device. Alternatively, mounting structure is formed directly on the retention member to secure the safety shield to the medical needle device.
