    Abstract: A controlled delivery syringe device includes a syringe barrel having a proximal end and distal end which defines a chamber for containing an injectable material. A plunger rod is associated with the syringe barrel and a plunger is secured thereto which is axially movable within the syringe barrel. A plurality of equally and sequentially spaced periodic features are associated with the plunger rod and a counter member is engageable with the periodic features. Application of a distally directed force to the plunger rod results in disengagement and reengagement of the counter member with the sequentially spaced periodic features on the plunger rod, enabling advancement of the plunger rod and plunger in the syringe barrel while providing tactile feedback of dose progression of the injectable material. A method of retrofitting a syringe with a device for injecting a metered dose of injectable material is also provided.

The deflection portion is positioned within the outer portion and is movable between a locked position and an unlocked position. The deflection portion in the unlocked position causes the outer portion to apply a second radial force to the cartridge or syringe.

  • Publication number: 20150073344
    Abstract: An intradermal injection device comprises a housing, a foot with an opening for passage of a needle; a reservoir movably mounted in the housing, and having a hollow space for holding a fluid; a hollow needle movably mounted in the housing and having a first end for penetrating the subject's skin and a second end for penetrating the reservoir, a plunger movably mounted in the housing for moving the needle through the opening for penetrating the subject's skin, and for pressing the fluid out of the reservoir. The reservoir is frictionally mounted inside the housing by first friction means, and the plunger is frictionally mounted to the reservoir by second friction means. The force to overcome the second friction is larger than the force to overcome the first friction.

  • Patent number: 8968258
    Abstract: A resettable drive mechanism for a medication delivery device comprising a housing and a drive member rotatable in a second direction for delivering a dose. A piston rod driven distally when a drive member rotates in the second direction. A stop member prevents rotation of the drive member in a first direction opposite the second direction, when the stop member engages the drive member. A clutch member is movable between a delivery and reset position. When the clutch member is in the delivery position, the stop member and the drive member engage and the drive member is prevented from rotating in the first direction. When the clutch member is in the reset position, the drive member and the stop member disengage. The drive member is rotatable in the first direction.
