20080208125 | Automatic Injection Devices - An injection device comprises a syringe ( | 08-28-2008 |
20100160894 | Automatic injection device - The invention provides an automatic injection device for providing a subcutaneous injection of a substance into a user, comprising: a housing having an open first end and a second end; a syringe movably disposed in the housing, the syringe including a barrel portion for holding the substance, a hollow needle in fluid communication with the barrel portion for ejecting the substance from the syringe, and a bung for sealing the barrel portion and selectively applying pressure to the substance to force the substance through the hollow needle; a plunger for first moving the syringe towards the first end such that the needle projects from the first end and subsequently applying pressure to the bung, the plunger including a rod connected at a first end to the bung, a compressible expanded central portion and a flange between a second end of the rod and the compressible expanded central portion; and a biasing mechanism for biasing the plunger towards the first open end of the housing, the biasing mechanism disposed about the second end of the rod between the flange and the second end of the housing. The present invention also provides methods and kits for using an automatic injection device, and methods and kits for promoting an automatic injection device comprising a medication based on advantageous properties of the device as compared to a pre-filled syringe. The invention also provides methods and kits for training a recipient on use of the automatic injection device. | 06-24-2010 |
20110196311 | INJECTION DEVICES - An injection device has a main drive module which can be screwed into the back of a syringe housing to prepare the injector ready for use. The drive module has a firing button and a drive plunger released for forward movement by pressing the firing button. The syringe housing slideably receives a syringe holder whose forward movement is initially prevented by internally directed barbs on a cylindrical latching sleeve. The latching sleeve is acted upon by a release ring on the drive module such that as the drive module is screwed onto the syringe housing, the release ring splays the cylindrical shell to release the syringe carrier for forward movement. The barbs also act as a latch to capture the syringe carrier in its rearward position when the drive module is unscrewed from the syringe housing, which returns the barbs to their initial position before the syringe holder returns to its initial position. | 08-11-2011 |
20110313398 | AUTOMATIC INJECTION DEVICES - An injection device comprises a syringe extendible against a spring bias from a retracted position in a housing to a projecting injecting position. A spring biased plunger has collapsible elbows which, when the plunger is released, initially engage the end of the syringe to drive it to the projecting position, whereupon arresting of the syringe movement causes the elbows to collapse inside the syringe to allow the plunger to engage and drive the bung. | 12-22-2011 |
20120197209 | RELATED TO AUTOMATIC INJECTION DEVICES - An injection device comprises a syringe extendible against a spring bias from a retracted position in a housing to a projecting injecting position. A spring biased plunger has collapsible elbows which, when the plunger is released, initially engage the end of the syringe to drive it to the projecting position, whereupon arresting of the syringe movement causes the elbows to collapse inside the syringe to allow the plunger to engage and drive the bung. | 08-02-2012 |
