Device for medicament delivery with syringe-like usability having a restraining mechanism A device for medicament delivery with syringe-like usability comprising at least one grip, at least one medicament container holder, and at least one plunger rod being substantially rotationally fixed relatively to the grip. The medicament container holder (13) is movable towards the grip in a longitudinal direction of the device, and rotation of at least one rotatable part (40), which is rotatable relatively to the grip and substantially inhibits movement of the plunger rod (20) in a longitudinal direction for dose delivery when in at least one locking position until being rotated, is restrained by at least one restraining member (42) abutting or being connected to the rotatable part (40) and the grip (30) until the medicament container holder is moved towards the grip for interacting with the at least one restraining member.

A fluid delivery device comprises a fluid reservoir for containing medicament. The fluid reservoir is sealed proximate one end with a sliding seal piston. A delivery path is configured to fluidly couple the fluid reservoir and a patient wearing the fluid delivery device. A basal engine mechanism is configured to directly or indirectly move the sliding seal piston in the fluid reservoir at a controlled basal rate. A bolus mechanism configured to move the basal engine relative to the fluid reservoir and directly or indirectly move the sliding seal piston in the fluid reservoir a discrete bolus amount at a time.

A quantitative syringe-type ejector capable of ejecting the contents packed in one syringe in small quantities is provided. The quantitative syringe-type ejector includes a syringe (10) and a plunger (P). The plunger (P) includes a piston holding member (30) and a plunger operation member (40). The piston holding member (30) has at least one arm (33) having: a slide projection (34) slidable on an inner peripheral surface (10f) of the syringe (10); and a lock projection (35) to be releasably locked to a back end (10e) of the syringe (10). The plunger operation member (40) has a lock part (47) to be releasably locked to the back end (10e) of the syringe (10).

A dispensing mechanism for administering a dosage of a medicament includes dosage setting means (7) for setting the dosage of a medicament to be administered; expelling means (15) for expelling a medicament from a medicament container; and coupling means (21) operatively coupled with the dosage setting means (7) and the expelling means (15), wherein the coupling means (21) is arranged to convert displacement of the dosage setting means (7) into a displacement of the expelling means (15) in a first direction, wherein the expelling means (15) includes a ratchet means (18a, 18b), and wherein the mechanism includes a first and a second independently moveable resisting pawl (14a, 14b) means facing a common side of the ratchet means (18), the first and the second resisting pawl means (14a, 14b) being configured to engage with the ratchet means (18a, 18b) and resist displacement of the expelling means (15) in a second direction opposite to said first direction.
摘要:
The present disclosure concerns a counting mechanism for a drug delivery device, comprising a first counting member comprising an interaction element, a second counting member comprising engagement elements that are configured to engage with the interaction element of the first counting member, and a separating member, wherein the first counting member is moveable relative to the separating member between a first and a second relative position, and the separating member is configured to prevent an engagement of the interaction element with the engagement elements when the first counting member is in the second relative position with respect to the separating member. Further, the present disclosure concerns a drug delivery device comprising said counting mechanism.
