Patent number: 10383656Abstract: An introducer needle assembly including a compressible section between the rigid needle and the hub. Once the vessel is entered as determined by blood entering the syringe, the compressible section of the introducer needle is occluded by compressing the section with the thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. The operator then can begin threading a guidewire down the device which is now easier to enter because blood is not coming out of the hub thus obscuring the lumen.Type: GrantFiled: December 22, 2015Date of Patent: August 20, 2019Assignee: Medical Components, Inc.Inventors: J. Daniel Raulerson, Mark S. Fisher

Patent number: 10300205Abstract: An autoinjector having a body (1; 2), a reservoir (S), a piston (P), a needle (A), and a piston rod (5) co-operating with the piston. The piston rod is movable between a first rest position, a second pricking position, and a third injection position. An actuator spring (6) is provided to urge the piston rod towards its pricking position and then towards its injection position. A force-adjustment system (7, 8) exerts a force (F1, F2) on the piston rod (5). The force (F1) opposes the force exerted by the actuator spring at the end of pricking to decrease the force exerted on the reservoir by the piston rod at the end of pricking, and the force (F2) adding to the force exerted by the actuator spring at the beginning of injection, to amplify the force exerted on the piston by the piston rod at the beginning of injection.Type: GrantFiled: July 4, 2014Date of Patent: May 28, 2019Assignee: APTAR FRANCE SASInventor: David Fabien
