Patent number: 10335555Abstract: A pneumatic retractable syringe has a plunger having an interior retraction lumen. The plunger and syringe barrel have cooperating locking elements so that the plunger is locked after use within the syringe barrel. After injection of medicament is completed, the needle is retracted into the lumen by compressed gas that is released from a gas cell within the syringe when the gas cell is ruptured just before the plunger reaches the end of its downstream path of travel.Type: GrantFiled: April 24, 2017Date of Patent: July 2, 2019Assignee: L.O.M. Laboratories Inc.Inventor: John Klippenstein

Patent number: 10195364Abstract: A gas release cell for use with pneumatically actuated sharps-containing medical devices. The gas release cell has a rigid outer shell and a sealing membrane sealingly engaged with the rigid outer shell. A compressed propellant is retained within the gas release cell by the sealing membrane, and the sealing membrane is rupturable to actuate the medical device by releasing compressed propellant from the gas release cell.Type: GrantFiled: March 26, 2014Date of Patent: February 5, 2019Assignee: L.O.M. Laboratories Inc.Inventors: Allan Andersen, Lionel Stuart Matthews, Scott E. Castanon

Publication number: 20170239425Abstract: A pneumatically activated retractable-needle syringe comprising a syringe barrel, a plunger, a needle, a needle hub, a locking tip, a propellant gas release cell and a rupture mechanism is provided. The plunger is slidably disposed within and sealingly engaged with the syringe barrel, the plunger having a retraction lumen defined for receiving a needle when the retractable-needle syringe is actuated. The needle is coupled to a distal end of the syringe barrel and in fluid communication with a medicament chamber defined within the syringe barrel distally of the plunger. The needle hub is for securing the needle at the distal end of the syringe barrel, the needle hub being initially secured within a false wall against a loading force or an injection force applied by a user, and releasable from the false wall in response to a post-injection force applied by a user.Type: ApplicationFiled: October 30, 2015Publication date: August 24, 2017Applicant: L.O.M.
