  • Patent number: 8118788
    Abstract: A pre-filled hypodermic syringe includes a tubular body having two open ends and containing a fluid to be administered to a patient; a plunger which, having at one of its ends a piston mounted to slide in the tubular body, passes through the opening of the first end of the tubular body; a tip for connection in the form of a cone of the Luer or Luer-Lock type, for example for connecting to a needle or to a drip, intended to pass the fluid that is to be administered and comprising a tubular part communicating with the opening of the second end; the tip comprising an obturator connected by a frangible region to the free end of its tubular part, the syringe being made of a synthetic material and obtained by molding, the obturator being molded as one piece with the tip and the tubular body.

  • Patent number: 7938816
    Abstract: 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.

  • Publication number: 20090024095
    Abstract: The invention concerns a syringe comprising: a body including a cylindrical side wall having an open upstream end with an inner annular rim and a downstream end closed by a transverse wall provided with an orifice; a shaft equipped with a plunger having at least two annular sealing lips between which is defined at least one annular chamber. The shaft, which can slide inside the body, defines inside the body an inner chamber designed to be at least partly filled with a content. Delivery passages provided inside the body are configured to communication said annular chamber of the plunger with the outside of the body or with the inner chamber of the body, when the plunger is abutting against the annular rim.

  • Patent number: 7261707
    Abstract: 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.

  • Patent number: 6461333
    Abstract: 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.

  • Patent number: 6416498
    Abstract: This device comprises: a syringe body equipped with an access which may be connected in succession to a filling member, such as a needle, and to an infusion line fitted with a non-return valve to allow liquid to pass from the syringe into the line; a housing mounted so that it can slide in leaktight fashion inside the body so as to vary the volume of a chamber which it delimits with the body of the syringe; an element which, forming a piston, mounted on the housing and in contact with the chamber, is able, according to its position, to create a raised pressure or reduced pressure in the chamber; means for moving the piston-forming element back and forth.

  • Patent number: 5779677
    Abstract: 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.
