Patent number: 7938816Abstract: The invention relates to a medical bag which is intended for the infusion of a medicament by means of gravity. The inventive bag comprises: at least two compartments, namely a first compartment (1) containing a medicament in the form of a solution and a second compartment (2) containing a rinsing solution; and means for separating/communicating the compartments, which prevent the rinsing solution from automatically entering the medicament compartment except at the end of the infusion period. The rinsing solution ends the infusion, by rinsing the medicament bag and the infusion line, such as to prevent any risk of contamination or leakage of residual medicament from the bag or line.Type: GrantFiled: April 8, 2010Date of Patent: May 10, 2011Assignee: Laboratoire AguettantInventor: Pierre Frezza

Patent number: 7261707Abstract: The invention concerns an ampule comprising a tubular body (2) made of synthetic material having two chambers (3, 4) tightly isolated by a membrane (9) capable of being perforated or a removable or frangible wall, one (31) of which contains the liquid or the powder (6), and the other is accessible from outside to be connected during transfer, the frangible membrane (9) or wall being arranged at the end of a tube (8) integral with the ampule and emerging into the chamber (4) capable of communication with outside, said tube (8) containing a tubular element (14) having a pointed tip (17) oriented towards the membrane. The tubular element (14) and the tube (8) comprise means (13, 16) preventing the tubular element (14) from being separated from the tube (8) after one has been mounted into the other.Type: GrantFiled: December 20, 2001Date of Patent: August 28, 2007Inventors: Pierre Frezza, Alain Botella

Patent number: 6461333Abstract: This syringe comprises a tubular piece surrounding the body of the syringe and driving the stem of the plunger of the syringe. During injection, the tubular piece slides forward on the body. At the end of injection the tubular piece detaches from the stem and, its front part can continue to slide in order to sheathe the needle.Type: GrantFiled: July 10, 2000Date of Patent: October 8, 2002Assignee: Laboratoire AquettantInventor: Pierre Frezza

Patent number: 5779677Abstract: The injector has a reservoir containing a drug. The injector has a tubular body with a tubular wall, a plunger, a needle and a plunger rod. The tubular body also has two springs. The first spring is compressed from bearing on a part of the inner surface of the tubular body and on a piece that is connected to the plunger rod. The first spring pushes in the direction in which the needle protrudes. The second spring acts in the opposite direction of the first spring. The second spring is compressed by bearing on a part of the inner surface of the injector body and on a ring. The force exerted by the second spring is greater than that exerted by the first spring. The ring is slidably mounted and is capable of entraining the reservoir in the direction of the retraction of the needle. The ring is blocked by a movable abutment. The plunger rod cooperates with the movable abutment to release the second spring and cause the retraction of the needle.Type: GrantFiled: August 1, 1996Date of Patent: July 14, 1998Assignee: Laboratoire AguettantInventor: Pierre Frezza
