  • Patent number: 5540674
    Abstract: A parenteral solution container having a dual use access port used for both the administration of fluids to a patient as well as for the addition of fluids to the container, includes a generally cylindrical wall with an axial passage therethrough. A fluid-tight sealing means, having a reseal member that includes a slit therein to enable the reseal member to be pierced with a blunt, metal cannula, or sharp needle is removably attached to the dual use access port. When the dual use access port is used in its fluid addition capacity, the reseal member is attached to the wall and a blunt cannula is passed through the reseal member. Once the blunt cannula has been completely inserted, fluids may be added to the container. To use the dual use access port in its administration capacity, the sealing means is completely removed from the wall. A piercing pin is inserted into the wall creating a fluid-tight seal so that fluids may be administered to a patient.

  • Patent number: 5279602
    Abstract: A suction drainage control system that reduces an operator's exposure to infectious waste by permitting waste-treating material to be dispersed into a sealed chamber in which the infectious waste is contained. The sealed chamber includes a cover with a flexible liner sealed to and suspended therefrom. A reservoir having a closure is provided inside the sealed chamber for storing the waste-treating material, which reservoir is opened by manipulating the flexible liner to remove the closure.

  • Patent number: 5190525
    Abstract: A drug infusion manifold for controlling the infusion of drugs and/or other solutions into an intravenous patient feed line. The manifold includes a housing defining an elongated in-line flow channel that communicates at one end with a carrier fluid inlet line and at the other end with the patient feed line. A plurality of spaced apart drug inlet openings are formed in the housing in communication with the flow channel. Each of the inlet openings is provided with a check valve assembly that includes a valve member defining an inlet socket portion and a valve stem portion that extends into the flow channel. The valve stem portion has a cylindrical side wall that defines an inlet passage that communicates with the socket portion. A plurality of lateral inlet ports extend through the side wall. An elastic sleeve member is received about the valve stem portion in covering relationship with the inlet ports. The valve stem portion is in-line with the flow of carrier fluid through the flow channel.

  • Patent number: 5185007
    Abstract: A suction drainage control system wherein waste-treating material is released into a sealed chamber. The chamber comprises of a cover with a flexible liner sealed to and suspended therefrom. A normally closed reservoir is provided on an underside of the cover for storing the waste-treating material therewithin as long as the reservoir remains closed. An externally operated actuator is provided on the cover for opening the reservoir to release the waste-treating material into the sealed chamber.
