A method and system for handling hazardous materials contained in a vial includes an isolation enclosure having an opening selectively sealable about the vial, a bag body portion, and a cap portion. A latching extraction element is attached to the cap portion and has a preceding engaging member to secure the vial to the isolation enclosure, an extraction member to be inserted into the vial and remove material therefrom, and a primary engaging member to secure the vial to the extraction member. A valve is mounted outside the isolation enclosure and controls the flow of fluid from the vial. An adaptor having a reseal member permits flow when coupled to the valve and restricts flow when uncoupled from the valve. Once uncoupled, the adaptor is removably associated with a second valve located remotely from the isolation enclosure, allowing fluid to pass into the second valve.

Hazardous material handling system and method

Combined pharmaceutical container and cap

Cap for a pharmaceutical container

An ambulatory infusion and/or KVO (keep vein open) system (12, 18) has a gas-pressurized bladder arrangement (12) including a gas barrier associated therewith. The system includes a flexible bag of solution (13) inserted in a sleeve portion (36) of the bladder arrangement (12). Internal gas pressure which is developed within the bladder arrangement by a selectively initiated chemical reaction exerts a continuing pressure against the solution bag (13) to cause the solution to flow therefrom. A tubing set (18) of the system includes a flow restrictor (24) which is sized for minimal flow rates for indwelling catheter patency maintenance.

Ambulatory energized container system

A system is provided for the delivery of a liquid anesthetic agent ti ab anesthetic vaporizer. The system includes a supply container having a spout defining an outlet through which the agent can be discharged. A reservoir is provided in the vaporizer for holding the agent, and a receiving station is provided on the vaporizer for receiving the container spout. The agent flows from the container through the spout by gravity into the reservoir. The container spout is located at the station to define the maximum liquid level of the agent in the vaporizer when gas flow into the container is blocked by the rising level of the liquid agent. In one embodiment, a frangible seal is provided in the container, an outlet valve is provided in the container, and an inlet valve is provided in the receiving station. The valves open automatically as the container is inserted into the receiving station of the vaporizer. Also, the container spout is preferably movable relative to a collar so as to automatically effect rupture of the frangible membrane as the container is inserted into the receiving station of the vaporizer.

Anesthetic vaporizer filling system

A solution pumping system is disclosed which is embodied as a disposable pump cassette including a self-contained positive displacement pump, and an associated pump driver including a reciprocable pump piston for driving the pump of the cassette. This system is particularly suited for use in compounding in preparation of parenteral solutions for administration to patients. In order to promote high liquid output with minimum peak pumping pressures, the controls of the system operate to provide a 'square' pumping pressure waveform, thus optimizing performance of the system. This is achieved by selectively varying the velocity of the pump piston during its operation.

Solution pumping for maximizing output while minimizing uneven pumping

A solution administration apparatus for patient care, for use with an associated solution administration system, which apparatus includes a laser drilled orifice flow control device to provide a controlled, predetermined flow rate of solution to the patient. The apparatus includes a tubing set and a laser drilled orifice flow restrictor, formed in a body, and in fluid communication therewith, for use with an associated fluid supply container. The system provides a controlled, predetermined flow rate of solution to the patient which is independent of, and relatively constant over minor variations in solution supply pressure and viscosity.

Solution administration apparatus with orifice flow control device

A latching piercing pin useable to retain the pin and an associated fluid vial in latching relation. Latching members provided on the pin engage a peripheral lip provided on the end cap of the vial to maintain the latching relation between the pin and the vial. The pin is useable with vials and end caps of varying sizes, although larger end caps may require the mounting of a locking ring on the end cap of the vial to receive and engage the latching piercing pin.

Latching piercing pin for use with fluid vials of varying sizes

An ambulatory infusion system includes a spring-pressurized reservoir to facilitate portable use of the system. The system includes a liquid-filled flexible container, and a pair of opposed platens between which the flexible container is removably positionable. Energy-storing, clip-like biasing springs act against the platens to urge them toward each other, thereby effecting pressurization of the liquid within the container. A tubing set of the system preferably includes a non-adjustable flow restrictor, which may be sized for relatively low flow rates to permit the system to be used for catheter patency maintenance.

Ambulatory infusion system with spring-pressurized reservoir

A drug infusion manifold that includes a housing defining a plurality of spaced apart fluid chambers that have a closed first end portion and an opposing second end portion. The second end portions of immediately adjacent chambers are in fluid communication through channels extending therebetween. A plurality of spaced apart fluid inlets are formed in the housing in fluid communication with a corresponding fluid chamber. A check valve means is provided in each fluid chamber for directing drugs and/or solutions from the inlets into the chamber and precluding fluid flow from the chamber. An outlet is formed in the housing in direct fluid communication with at least one of the chambers.

Automated drug infusion manifold

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.

Drug infusion manifold

For use in preventing spillage in a continuous ambulatory peritoneal dialysis apparatus, a two-part spike holder which automatically occludes a flexible tubing connected to the hollow spike as the spike is mounted in the holder, the two parts of the spike holder being pivotally interconnected and biased toward one another.

Spike holder

An improved motorized transfer mechanism for use in a continuous ambulatory peritoneal dialysis apparatus (CAPD) is provided for automatically transferring a piercing pin from the clamped port of a used container of used dialysis solution to the clamped port of a container of fresh dialysis solution. The transfer mechanism is characterized by a track member extending between opposed aligned port mountings, an upstanding guideway adjacent to each port mounting and a rack formation located midway between the opposite ends of the track member. The rack formation is rotatably engageable with a circular gear sector secured to the spike carrier disposed within the guideways of the track member. The linear movement between the opposed ports of the spike carrier is performed by a motor-driven drive screw. The intermediate 180 degree rotational movement of the spike occurring when the rack formation of the track member engages the circular gear sector of the spike carrier, both inverts the spike and positions it adjacent an ultraviolet bulb for sterilization thereof.
