Thus any contents of the syringe can flow unimpeded via the outlet into the tube and vice versa. A seal hermetically closes the outer end of the tube. Such a syringe assembly is filled from a medical-liquid-holding container also having an outlet opening provided with a respective such tube whose outer end is similarly sealed. The syringe is filled by first unsealing and joining the outer ends of the tubes to each other in a sterile docking procedure, then aspirating the medicament through the unsealed and joined ends and resealing the tubes together, and finally cutting the tubes apart where they are sealed together to form two new seals on the tube outer ends.

  • Patent number: 5222948
    Abstract: An improved injection port (1) for a single-use syringe is described. One embodiment of the injection port has a one-way valve system for making it more difficult to reuse the syringe (2). The one-way valve system has a flap or diaphragm valve (6) housed in a valve chamber (11) at the proximal end of port cylinder (45). When the valve (6) is seated against valve seat (51) on valve cap (5), refilling of the syringe is blocked. During injection, the valve (6) unseats and moves toward radial ribs (7), allowing flow of medicament into the proximal end of a needle (2). Another embodiment of the injection port (1) includes longitudinal grooves (8) on the interior surface of the chamber (12) at the distal end of cylinder (45). The grooves (8) vent pressure from a Luer syringe inserted in the distal end of the cylinder (45).

  • Patent number: 5207654
    Abstract: A positive displacement ampule for storing a fluid therein and dispensing the fluid therefrom. The ampule includes an elongate vessel for storing the fluid having a large diameter base portion at one end thereof joined to a small diameter stem portion at the other end thereof, a piston disposed in the vessel at the base end thereof for forcing the fluid from the vessel, a fracture probe for fracturing the base end of the vessel and a needle for inserting into the fractured base end of the vessel and for piercing the piston such that one end of the needle protrudes outwardly from the vessel and the other end of the needle communicates with the fluid in the vessel. In this manner, the fluid is pumped from the vessel through the needle by pushing the piston in the direction of the fluid.

  • Patent number: 5181909
    Abstract: A medical syringe has a plunger bore (1 and 2) that is flexible. A hermetically-sealed glass ampule (3) containing a drug in the form of a liquid referred to generally as a sterile preparation (4) is placed in the plunger bore (1 and 2). When the plunger (1) is pulled outwardly a select distance to expose the flexible plunger bore (2), the glass ampule (3) is broken by hand-squeezing the plunger bore (2) against it. Liquid preparation (4) from the glass ampule (3) is directed through a check-valved orifice (16) at a tip of a resilient piston section (21) of the plunger (1). At the check-valved orifice (16), the preparation (4) enters into a syringe bore (6). There the preparation (4) can be injected through a conventional luer (38-40) and hypodermic needle (37) by the standard practice of depressing the plunger (1) into the syringe (7). Variations are provided for storing ampules of preparation either in or separately from the syringe. Embodiments are described for various adaptations.

    Abstract: An ampul comprising a container having a reduced neck which supports an integral closure part that is removable by tearing away frangible portions. The neck can be sealingly applied over the seating cone of a hypodermic syringe whereby the syringe and ampul are firmly joined as one unit. The ampul is preferably produced as a single piece of a thermoplastic synthetic such as polypropylene whereby the ampul neck has sufficient elastic ductility to be elastically expanded by applying it to the seating cone of the syringe, thereby to assure a firm coherence. To permit air to enter to container when suctioning off the ampul contents, the ampul neck has on its inside an axial ventilating means.

  • Patent number: 4776845
    Abstract: The rectal-stomal insert apparatus is used for occluding an opening in a patient's colon and preventing uncontrolled leakage during examination with a colonoscope. The apparatus includes an insertion member having an outer end, an inner end, and an exterior surface. The insertion member has an instrument channel and a separate and distinct suction channel each of which extends between the outer end and the inner end. The instrument channel is large enough to receive a colonoscope tube and is provided with a seal to seal around the colonoscope tube. An expandable occlusion member is coupled to the insertion member exterior surface. The occlusion member is made of a relatively soft material to sealingly engage and occlude the opening of the colon as the occlusion member is expanded. At the outer end of the suction channel is a longitudinal flange for receiving suction apparatus. A handle is provided at the outer end of the insertion member.
