An injector for ejecting an intraocular lens into an eye, comprises a longitudinal injector body, in which an injector piston rod can be guided in an axially displaceable manner, an injector nozzle at a front end of the injector body, in the direction of which the injector piston rod can be displaced, a displacement mechanism for pushing the injector piston rod forwards, and an actuating element for the manual actuation of the displacement mechanism.

The displacement mechanism includes a transmission mechanism, by means of which the actuating element and the injector piston rod can be placed in an articulated driving connection, and an operating region for the actuation of the actuating element is formed at a longitudinal side of the injector body.

Device for medicament delivery with syringe-like usability having a locking mechanism. A device for medicament delivery with syringe-like usability with at least one grip (30), at least one plunger rod (20) being substantially rotationally fixed relatively to the grip, and at least one locking mechanism (17) configured to substantially inhibit movement of the plunger rod in a longitudinal direction of the device for dose delivery when being in at least one locking position. The locking mechanism comprises at least one rotatable part (40) that is substantially fixed in a longitudinal direction, that is rotatable relatively to the grip, and that interacts with the plunger rod. The device comprises at least one indicator drum (60).

A dispensing device is provided to dispense a designated amount of a material on every dose delivery operation. The dispensing device includes a thumb pad, a cam drum coupled to the thumb pad, and a pawl nut comprising a one-way pawl. The thumb pad may be pulled out in a direction away from a distal end of the dispensing device for setting a dose of the material to be dispensed out and may be pushed in towards the distal end for delivering the dose. The cam drum includes a plurality of linear cam profiles and a plurality of helical cam profiles that may be disposed on a surface of the cam drum. The one-way pawl may engage with a ratchet disposed at a distal end of the cam drum and may prevent a rotation of the cam drum in an undesired direction.

Add-on module (100) for logging the value of an expelled dose from a pen-type drug injector (200), comprising a magnetic sensor system comprising first and second sensor means (745/746) as well as a mechanical dose setting and expelling mechanism comprising a magnetic clutch element (240/740) which rotates during drug expelling. The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

A syringe includes a monolithic barrel (12) being divided into two bore portions, a first bore portion (22) extending from the needle adapter partially towards the second axial end and a second bore portion (24) extending from the first bore portion to the second axial end, wherein the first bore portion is circular in cross section and the second bore portion has a cross sectional shape that at least partially extends beyond the radius of the first bore portion. The syringe includes a plunger (14) sized to fit within and move along the longitudinal axis of the first bore portion. A plunger rod (16) extends along the longitudinal axis of the monolithic barrel, the plunger rod including a first array of notches and/or protuberances (30) along at least a portion of its length. The syringe includes an insert (18) sized to fit wholly within the second bore portion, the insert defining a bore through which the plunger rod extends and including a first finger (36) extending into the bore defined by the insert for, in use, engaging the first array of notches and/or protuberances on the plunger.

A medication injection pen is provided comprising a housing (218), for housing a dose set knob (220), a leadscrew (226), a driver (224), a setback member (222), and a dose stop member (228). The dose set knob (220) is rotatable with respect to said housing (218) to set a desired injection dose, and comprises at least one internal thread (291). The leadscrew (226) includes a thread element by which it is advanceable in a first direction via a corresponding thread engagement, said first direction being that which expels medication from a cartridge (36). The driver (224) is rotationally fixed to said leadscrew (226) for preventing relative rotation therebetween, said driver (224) being rotatable in a first direction to rotate and advance said leadscrew (226) in said first direction. The setback member (222) is rotationally fixed to said driver (224) for preventing relative rotation therebetween.

The invention relates to a torsion spring driven injection device for ejecting set doses of a liquid drug. In a first aspect the torsion spring driven injection device is provided with a blocking structure which is operated by the rotatable display element such that the set dose can only be expelled when a certain minimum dose size has been set. In a second aspect the torsion spring driven injection device is provided with a release mechanism which secures that the set dose can only be expelled as one single full dose in one stroke. The two aspects can easily be combined such that the predetermined minimum dose size most be expelled as one single dose.

Flush syringe assemblies capable of creating pulsatile movement of the plunger rod as it moves in the distal direction within a syringe barrel, while preventing overpressurization of the catheter are provided. An exemplary flush syringe assembly includes a syringe barrel with a first pulsing element and a chamber with flush solution, a plunger rod with a stopper and a second pulsing element that interacts with the first pulsing element to provide an engagement force that causes pulsatile movement of the plunger rod and a thumb press slidably attached to the plunger rod with a pulse control element. The pulse control element is compressible to create a compression force that is greater than the engagement force of the first pulsing element and the second pulsing element.

A syringe exostructure includes a main body which removably receives a syringe having a syringe barrel and a syringe plunger. A drive plunger is reciprocatably mounted on the main body, and a plunger bar is slidably received in an axial channel on the drive plunger. The plunger bar is configured to removably couple to the syringe plunger when the syringe is introduced into the main body. A drive pawl assembly is fixed to an upper surface of the drive plunger and transfers forward motion of the drive plunger to the plunger bar as the drive plunger is advanced and disengages from the plunger bar when the drive plunger is retracted. A locking pawl assembly is fixed to the main body and extends through a slot formed in the bottom of the axial channel in the drive plunger. The locking pawl engages the plunger bar and allows the plunger bar to be advanced by the drive plunger as the drive plunger is advanced but prevents the plunger bar from being retracted by the drive plunger as the drive plunger is retracted.

The present invention relates to a syringe having a barrel, a plunger arranged to travel within said barrel and a plunger rod for driving the plunger in a bidirectional manner. The plunger rod is provided with a head at a distal end thereof and a plurality of protruding finger grip enhancing means axially spaced along a length of the plunger rod.
