Injection device

A method of sterilizing a cartridge that has a side wall and a medicant in the cartridge. The cartridge is placed within an outer sleeve and the outer sleeve is sealed to the side wall of the cartridge with a wiper seal to form a hermetic microbial barrier. A breathable microbial membrane is provided over one end of the sleeve. The cartridge and the outer sleeve are subjected to gas sterilization in a sterilization chamber. Any sterilizing gas remaining after sterilization is removed.

Method of sterilizing medical device

An injector comprising an outer housing, a generally longitudinally extending keyway formed in the outer housing, an inner housing located interiorly of the outer housing, a guide member mounted at one end of the inner housing, the guide member having at least one protrusion adapted to engage the keyway, a spring member, the spring member having a first end abutting the outer housing, a second end of the spring member abutting the guide member, a syringe mounted interiorly of the inner housing, a needle mounted on one end of the syringe, the syringe having a plunger and a plunger rod, a finger rest member mounted over the outer housing, the finger rest member being opaque to thereby prevent visual access to the keyway.

Injector

A reconstitution device comprising a cartridge () containing a first substance, the cartridge having a plunger () at one end and a piercable septum () at a second end, a vial () containing a second substance, the vial having a piercable septum (), a housing (), a cartridge needle hub (), the cartridge needle hub () having a needle () protruding therefrom, a vial needle hub (), the vial needle hub having a needle () protruding therefrom, the vial needle hub () and the cartridge needle hub (226) being releasably securable together, cartridge latches () holding the cartridge needle hub () within the housing, vial needle hub latches () extending to engage the housing, and a plunger rod (), the plunger rod having an inner portion () engageable with the plunger () of the cartridge, the plunger rod () having an outer portion () which is adapted to engage the vial needle hub latches () to release the vial needle hub () from engagement with the cartridge needle hub (), whereby the vial () and the vial needle hub () may be released from the housing.

Secure reconstruction device

Vial adaptor

An injection device for injecting, the injection device comprising a housing having an interiorly facing wall with the wall having a plurality of ribs formed thereon, the ribs defining a channel extending therebetween, a plunger rod mountable within the housing and having at least one protrusion engageable within the channel, a cylindrical body, a spring mounted at a distal end of the housing with the spring being biased between the distal end and a needle hub, and a pusher rod raised such that pressure thereon from the plunger rod will cause the pusher rod to enter the cylindrical body, the pressure causing the spring to act on the needle hub to move the needle hub and the cylindrical body upwardly within the housing such that a needle is in an enclosed position within the housing and cannot be reused.

A auto-injector device having a housing (), a cartridge for containing a medicament, a first needle tip () arranged to penetrate said cartridge, a second needle tip () for injecting said medicament into a target, said first and second needle tips being in fluid communication, a plunger rod () to move said cartridge so as to be pierced by said first needle tip, said plunger rod () having a recess () in an end thereof, the improvement comprising a battery (), a printed circuit board () electrically communicating with said battery, an electrically conductive element () having a first end in electric communication with said battery () and printed circuit board (), a second end within said recess () in said plunger rod (), said second end being electrically insulated, a coil spring () surrounding said electrically conductive element and being spaced therefrom, the arrangement being such that when said plunger rod () is activated, said second end of said electrically conductive element is released from said recess () in said plunger rod () and contacts said coil spring () to complete an electric circuit.

Auto-injector

An auto-injector pen has an outer housing () which has a proximal end () and a distal end (), an inner housing () having a cartridge () therein, the cartridge () containing a medicament and having one end thereof sealed by pierceable member (), a needle hub () having first and second piercing tips () which are in fluid communication, an actuating assembly () which moves an actuator from a first position to an activated position wherein the first piercing tip () extends outwardly of the outer housing () at the proximal end () and the second piercing tip () pierces the pierceable member (), a first trigger () located at the distal end () and a second trigger () located at proximal end, the arrangement being such that the second triggermust be activated to permit activation of the first trigger ().

A reconstitution arrangement for transferring the contents of a first container () with the contents of a second container () and subsequently retransferring the mixture to the first container (), the arrangement including a transfer device () having a fluid passageway extending between first and second ends (), a cartridge holder () secured to second end () of the transfer device, the cartridge holder () having a needle () with first and second piercing tips (), the first piercing tip () extending into the fluid passageway of the transfer device, a first container receiving portion () having the second piercing tip () extending therein and being arranged to receive the first container (), a housing () secured to the cartridge holder with a plunger rod () within the housing, and a cover () extending over the transfer device (), cartridge holder () and housing (), the cover and transfer device having an interlocking arrangement to prevent removal of the cover () until activated by the second container ().
