Individual coils may be formed to have a groove located along the length of the helix. When compressed, the novel member effectively takes on a cylindrical outer configuration. Because the groove is covered and sealed by the surface of the next turn of the helix when compressed, an enclosed helical flow path is formed in the compressed member. The invention may be an injection device using the novel flow path forming member or alternatively, the flow path forming member itself. | 10-28-2010 |
| 20100274185 | AUTOMATIC INJECTION SYRINGE ASSEMBLY - An apparatus for actuating a syringe. The syringe includes a barrel, a plunger and a needle. A needle shield is near the front of the barrel and is movable from a first position enclosing the needle and a retracted position wherein the needle is exposed. A spring abuts the plunger. A cap has an interior wall for engaging the spring and releasably engages the plunger. The spring is compressed between the plunger and the interior wall when the cap releasably engages the plunger. A resilient member releasably secures the cap in releasable engagement with the plunger and is movable from a first position to a compressed position when the needle shield is moved from its first position to its retracted position. The cap disengages the plunger when the resilient member is moved to the compressed position wherein the spring expands to provide a medicament delivery pressure to the plunger. | 10-28-2010 |
| 20100324480 | AUTOMATIC INJECTION SYRINGE ASSEMBLY - An apparatus for applying medicament delivery pressure to a plunger pad of a plunger of a syringe includes a spring having a first end and a second end, wherein the spring first end is operable to abut the plunger pad. The assembly also includes a shell including an interior and a first step therein. A cap is disposed within the shell interior. The cap includes a surface for engaging the spring second end. The cap is movable from a first position, wherein the shell first step retains the cap in releasable engagement with the plunger such that the spring is compressed between the cap surface and plunger pad, and a second position, wherein the cap disengages the shell first step such that the cap disengages the plunger such that the spring expands to move the barrel and needle forward as well as deliver medicament delivery pressure to the plunger pad. | 12-23-2010 |
| 20110319832 | PROTECTIVE GUARD FOR NEEDLES OF INJECTION DEVICES HAVING REMOVABLE NEEDLE ASSEMBLIES - Protection for the otherwise exposed sharp point of a needle of an injection device. A two part cover for the needle comprises a stationary base which engages the injection device, and a relatively movable cover. The cover is guided to slide longitudinally along the base by a groove-and-projection system. The projection is held in an initial position, and slides along the groove during injection. At the end of the injection, the projection is immobilized in the groove at a final position, and immobilizes the moveable cover in a deployed position covering the needle. | 12-29-2011 |
| 20110319833 | PROTECTIVE GUARD FOR NEEDLES OF INJECTION DEVICES - A self-deploying cover for protection against unintended pricks from injection devices. The cover comprises a base which engages the injection device, and a protective sleeve which covers the sharp point and moves relative to the base to expose and cover the sharp point. The sleeve is guided by a projection which rides within a generally V-shaped groove formed in the base. The groove comprises deflectable arms which deflect to pass the projection, but which oppose return of the projection after passing. The sleeve is spring urged to the extended position and is automatically withdrawn during injections. After an injection, the sleeve is locked into the extended position by the last deflectable arm. | 12-29-2011 |
