Abstract: An apparatus for administering parenteral liquids from a parenteral fluid container which provides a sufficient quantity of parenteral liquid to be administered at a slower than normal rate so as to afford a keep-vein-open (KVO) means. The apparatus utilizes a first orifice to afford a faster flow rate than a second orifice spaced away from the first orifice. The preferred means for regulating different flow rates of fluid through the two orifices are the dimensions of the orifices and filters having different mesh sizes. When the parenteral liquid is maintained in the reservoir in contact with the first orifice with the faster flow rate, liquid will pass through both orifices at a predetermined regular rate. When liquid no longer contacts the first orifice, as when the fluid container is depleted of liquid, the second orifice then comes into effect to afford a slower rate of liquid until a new container can be supplied.

Abstract: A prefilled, ready to use, disposable syringe wherein a fluid medicament and a diluent therefor are sealed in two separate telescoping syringe barrels. A medicinal powder is sealed in an outer barrel adjacent the nozzle section by means of a pierceable stopper and the diluent is sealed in an inner barrel between another pierceable stopper and a plunger stopper. A double-pointed cannula is positioned between the two pierceable stoppers by means of a telescoping guide arrangement. Movement of the plunger stopper inwardly in the inner barrel initially effects a piercing of both pierceable stoppers and intermixing of the medicinal powder with the diluent. Continued movement of the plunger stopper will expel the mixed medicament from the syringe.

Abstract: An additive transfer device for storing and transferring of a medicament to a solution container such as an I.V. bag having an exposed port. The transfer device is accommodated in the neck of an additive container having a pierceable sealing element. A holder member for a doubled pointed end piercing member engages a cap covering the tubular neck and affords a movement of the piercing member toward the sealing element to pierce it. Guide means extend from the holder member and fit over the tubular port of the I.V. bag. When the opposing pointed end of the piercing element is pierced through the I.V. port, communication can be made between the additive container and the I.V. bag. In a preferred manner, the contents of the additive container are expelled by collapsing the walls which force the medicament into the I.V. bag by means of the piercing element.

The unidirectional unit obviates severing of the catheter by the needle, which can occur when the catheter is retracted in bidirectional units. Preferably, the catheter placement unit comprises an overcap or cover which is only coupled to the reel of the reel-type catheter placement unit by a ball clutch when the overcap is rotated in a direction that advances the catheter from the unit.

Abstract: A unidirectionally valved drip chamber, inlet port assembly useful for liquid collection containers, e.g., urinary collection bags, or other containers requiring antireflux protection is disclosed. The assembly comprises a flexible, hollow, substantially frusto-conical unidirectional valve fixedly mounted between the inlet and outlet of the assembly. The valve has a closed top and open bottom and is normally closed against a complementary substantially frusto-conical valve seat. The conical wall of the valve flexes away from the valve seat to allow liquid to flow from the inlet to the outlet. Liquid flowing from the outlet towards the inlet forces the valve more firmly against the valve seat so that the valve remains closed to such reverse or reflux flow.
