Disposable syringes

Claim 2

A syringe for vaginal douche and enemas and the like, said syringe including: (a) a flexible container having an accordion configuration; (b) a discharge conduit adapted for fluid-tight connection to the container; (c) a manipulative shutoff valve associated with said discharge conduit, said valve when open permitting the flow of fluid from the container, said conduit being semiflexible and having a substantially circular cross section, the conduit having at least one stiffening rib locally formed as a part of the outer surface of the conduit and providing an assist to insure bending of the conduit into a pinch configuration to provide fluid-flow cutoff when the conduit is bent substantially at a right angle to and away from the stiffening rib whereby in this bent condition the sides of the conduit are brought together to inhibit flow therethrough; (d) means for releasably retaining this conduit in the bent condition during storage and shipment until the conduit is straightened for fluid flow and use, and (e) a discharge nozzle attachably associated with the outlet end of the conduit.

Claim 3

A syringe as in claim 1 in which the portion of the conduit which is to be bent includes two stiffening ribs extending axially along the conduit, said ribs being about 70 to 90° apart.

Claim 4

A syringe as in claim 1 in which that terminal end of the conduit portion of the shutoff valve which is below the pinch fold includes ferrule-like means formed on the conduit, said means adapted to receive and retain the inlet end of a length of tubing leading to the discharge nozzle.

Claim 5

A syringe for vaginal douche and enemas and the like, said syringe including: (a) a flexible container of accordion configuration; (b) a discharge tube having a connected semi-flexible conduit having a substantially circular cross section, said conduit having at least one stiffening rib locally formed as a part of the outer surface of the conduit connected to the container in a fluid-tight manner; (c) at least one of the component portions of a fluid mix to be used with said syringe contained in this flexible container; (d) a manipulative cutoff valve associated with said discharge tube, said valve when open permitting the flow of fluid from the container, this valve being brought to a closed condition with a bending of the conduit into a pinch configuration resulting in the fluid-flow cut off when the conduit is bent substantially at a right angle to and away from the stiffening rib whereby in this bent condition the sides of the conduit are brought together to inhibit fluid flow therethrough; (e) means for releasably retaining this conduit in the bent condition during storage and shipment until the conduit is unbent for fluid flow and use, and (f) a discharge nozzle attachable to the outlet end of the discharge tube.

Claim 6

A syringe for vaginal douche and enemas and the like, said syringe including: (a) a flexible container of accordion configuration; (b) a discharge tube having a connected semi-flexible conduit having a substantially circular cross section, said conduit having at least one stiffening rib locally formed as a part of the outer surface of the conduit connected to the container in a fluid-tight manner; (c) at least one of the component portions of a fluid mix to be used with said syringe contained in this flexible container; (d) a manipulative cutoff valve associated with said discharge tube, said valve when open permitting the flow of fluid from the container, this valve being brought to a closed condition with a bending of the conduit into a pinch configuration resulting in the fluid-flow cut off when the conduit is bent substantially at a right angle to and away from the stiffening rib whereby in this bent condition the sides of the conduit are brought together to inhibit fluid flow therethrough; (e) means for releasably retaining this conduit in the bent condition during storage and shipment until the conduit is unbent for fluid flow and use, and (f) a discharge nozzle attachable to the outlet end of the discharge tube.

Claim 7

A syringe as in claim 4 in which the means for releasably retaining the bent conduit is a pair of opposed gripping fingers carried by the and on the accordion container.

Claim 8

A syringe as in claim 4 in which the portion of the conduit which is to be bent includes two stiffening ribs extending axially a short distance along the conduit, said ribs being about 70° to 90° apart.

Claim 9

A syringe as in claim 4 in which that terminal end of the conduit portion of the shutoff valve which is below the pinch fold includes a ferrule-like means formed on the conduit, said means adapted to receive and retain the inlet end of a length of tubing disposed to be connected to a discharge nozzle.
