The invention relates to an injection supporting device for a syringe. The syringe comprises a cartridge for a medicament and may comprise an injection needle extending in a z-direction from the cartridge to dispense the contents of the cartridge. Alternatively the injection needle may be part of the injection supporting device itself. The injection supporting device comprises a housing to receive at least a part of the cartridge, a needle shield and a resilient member coupled to the needle shield and the housing. The needle shield comprises a distal portion and a proximal portion, a distal opening in a front end of the distal portion and a needle guide for guiding the injection needle towards the distal opening. The needle shield is slidably attached to the housing and slidable relative to the housing along the z-direction between a guarding position covering a tip of the injection needle and an injection position in which a front end portion of the injection needle extends through the distal opening of the needle shield. The resilient member urges the needle shield towards the guarding position.

Injection supporting device for a syringe and injection device

The present invention relates to a drug delivery comprising a housing () adapted to retain a cartridge () and a piston rod (), the piston rod () being adapted to drive a piston () so as to engage the piston () into the cartridge () in response to operating an operating button (), and an indicator means () being capable of revealing usage related information of the drug delivery device (), the indicator means () being movable with respect to the housing (). Furthermore, using indicator means () on a drug delivery device (), wherein the so as to reveal usage related information of the drug delivery device (), wherein the indicator means () being movable with respect to a housing () of the drug delivery device () is disclosed.

Drug delivery device

A counter mechanism useable with a dry powder inhaler is disclosed. The mechanism features first and second indicator members rotatable about a central axis. The indicator members have counting indicia visible to indicate inhaler doses remaining or dispensed. A coupling transmits rotary motion from the inhaler to the second indicator member when the inhaler is charged with a dose. A slave wheel, rotatable about an axis offset from the central axis, has a drive transfer wheel on one face and a gear on an opposite face. The gear engages the second indicator member, the drive transfer wheel intermittently engages and rotates the first indicator member in response to rotary motion of the second indicator member.

Slave wheel counter mechanism useable with an inhaler

A rotatably actuated counter is disclosed. The counter includes a ratchet driven unit wheel nested within a tens wheel. Each wheel has a radial face displaying counting indicia. The tens wheel is transparent, allowing the indicia on the unit wheel to be viewed adjacent to the indicia on the tens wheel to provide a total count. A slave wheel is positioned between the unit and tens wheels. A gear on one face of the slave wheel engages gear teeth on the tens wheel. A Geneva mechanism on the other face is engaged by a foot on the unit wheel once per rotation. The wheels are rotatably mounted within a housing having a sidewall with a window through which the count indicia may be viewed. The unit wheel rotates in ten increments and then rotates the tens wheel through one increment by engaging and rotating the slave wheel.

Mechanical doses counter for a powder inhaler

Provided herein are dry powder inhalers for the delivery of metered doses of medicament, counters associated with the inhalers for counting and displaying the number of doses administered or remaining within the inhaler, and methods of use thereof.
