Various embodiments comprise endoscopes (e.g., arthroscopes) for viewing inside a cavity of a body. The endoscopes may include a tip, at least one solid-state emitter such as light emitting diode (LED), located at the distal end of the endoscope, an elongated member. The elongated member may include a plurality of lenses for transmitting light received from the tip member and an elongated conducting member for providing electric power to the solid-state emitter. The elongated conducting member may include conducting lines embedded in a flexible elongated insulating membrane. The tip member and the elongated member may be configured to dissipate heat generated by the solid-state emitter.

A patient controlled liquid drug administration device providing either or both of a continuous flow of a liquid drug, as well as successive boluses thereof, to be self-administered by a patient while allowing delivery of only full bolus volumes. The device includes a reciprocating pump defining a closed internal reservoir having a fixed first wall, and a second, flexible wall that is axially movable in relation to the fixed wall between reservoir-full and reservoir-empty positions. A lock is connected to a push button that activates a plunger of the pump. The lock has a first position preventing the push button from being depressed when the push button is in an extended position and the plunger is in a reservoir-empty position and a second position permitting the push button to be depressed when the push button is in an extended position and the plunger is in a reservoir-full position.

The present invention relates to an externally operated alpha port for a rapid transfer port (RTP) system such as those found in isolation barrier systems. Means are provided for the actuation by the operator of the alpha port door locking system externally of the isolation barrier to facilitate the locking and unlocking of the alpha port door without requiring gloved entry into the isolation barrier. Means are also provided for opening and closing of the alpha port door with the actuation by the operator of a lever external to the isolation barrier.

A device for dispensing fluid to a patient enabling either or both of a continuous flow, as well as successive, large-volume boluses. A first reservoir provides a source of fluid under pressure. A bolus flow path provides for the delivery of a bolus dose of fluid and an optional continuous flow path provides a continuous flow rate of fluid. Both flow paths are in fluid communication with the source of fluid. A bolus delivery system in fluid communication with the bolus flow path receives fluid from the first reservoir, expands to pressurize fluid, stores the pressurized fluid, and dispenses the pressurized fluid while avoiding bolus refill until enabled to expand in a subsequent delivery cycle. An actuator releases fluid from the bolus delivery system such that when actuated by the patient, fluid is permitted to flow out of the bolus reservoir to the patient without further action by the patient.

Large-volume bolus patient controlled drug administration device

A patient controlled liquid drug administration device is provided that enables either or both of a continuous flow of a liquid drug, as well as successive, large-volume boluses thereof, to be self-administered to and by a patient while avoiding bolus refill during bolus delivery or after bolus delivery but before an intake stroke of the pump occurs. The device includes an elongated housing having an axial cavity extending through it with a reciprocating pump mounted at a bottom end thereof. The pump defines a closed internal reservoir and includes a first wall, or seat, that is fixed in the cavity, and a second, flexible wall that is axially movable in the cavity in relation to the fixed wall between reservoir-full and reservoir-empty positions. The pump includes an inlet port that is connectable to a source of a pressurized liquid drug by an inlet conduit, and an outlet port subcutaneously connectable to the patient by an outlet conduit, both conduits extending out the bottom end of the housing. An outlet clamp is mounted in the cavity to move between a closed position constricting the outlet conduit of the pump, thereby preventing the flow of the liquid drug through the outlet conduit, and an open position. An inlet clamp is mounted in the cavity to move between a closed position constricting the inlet conduit and thereby preventing the flow of liquid through it, and an open position disengaged from the inlet conduit, thereby allowing the flow of liquid through it.

A leak testing control assembly for a leak testing system of a type that cooperates with a test part interface that is coupled with a test part. In a broad aspect the leak testing control assembly includes a working fluid generator for applying a working fluid having a fluidic pressure to a test part. A flow controller assembly is coupled to the working fluid generator. The flow controller assembly includes a flow controller element for controlling the flow rate of the working fluid. A pressure level measuring element is positioned relative to the test part for measuring the fluidic pressure. A control system is coupled to the flow controller assembly and the pressure level measuring element. A user interface is coupled to the control system for providing user interaction with the leak testing control assembly. During operation, the control system 1) facilitates application of the fluidic pressure at a selected relatively constant flow rate; and, 2) interprets the value of the fluidic pressure, after the application of the fluidic pressure at the selected relatively constant flow rate, to determine whether the test part is free of leaks.

System and method for leak detection

A flexible container is provided for the storage and administration of medical solutions. The container incorporates a transparent front sheet made from a planar layer of a polymer and an opposing rear sheet. The rear sheet is made from a planar laminate layer. The front and rear sheets are sealed together along a common peripheral edge to form a volume enclosure. The volume enclosure is constructed of materials having high oxygen and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front and rear sheets outwardly and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments, separated by peelable seals, for containing a diluent and a medicament. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient.

The system includes an enclosure for providing a closed volume for bactericide vapor. The enclosure has a container access opening formed therein for providing vapor communication between a container and the closed volume. A container interface assembly at the container access opening positions, locks and seals the container to the enclosure. A container door removal system is partially contained within the enclosure and is operably engaged with the enclosure and attachable to a container door of the container for separating the container door from the container. The container door removal system includes an actuator element located external to the enclosure. A vapor injection system is included having an inlet and an outlet for the bactericide vapor. During operation, a container is attached to the container interface assembly and the container door is separated from the container by operating the actuator element of the container door removal system providing vapor communication between the closed volume and the volume within the container. The bactericide vapor may be introduced into the enclosure and the container via the vapor injection system.

Decontamination system for use with a rapid transfer port

The present invention is a container assembly for use with a rapid transfer port. The rapid transfer port (RTP) is of the type having an RTP door, an RTP circular seal around the door, and spaced RTP indentations. The RTP requires rotation of the device being attached thereto. The container assembly includes a circular ring member having an interface end and a bearing system end. The interface end includes a first set of ring member protrusions for engagement with RTP indentations of an RTP and a container assembly circular seal for providing sealing engagement of the ring member and the RTP. A circular enclosure door is concentrically positioned within the ring member. The enclosure door includes a first set of enclosure door indentations for engaging associated RTP door protrusions and a second set of enclosure door indentations for engaging a second set of ring member protrusions. The container assembly circular seal further provides sealing engagement of the ring member and the enclosure door. A bearing system is engaged with the bearing system end of the ring member. An enclosure having a bearing system engagement portion is engaged with the bearing system wherein the bearing system provides relative rotation of the ring member and the enclosure about a central axis of the ring member. The enclosure further includes an enclosure seal operatively engaged with the ring member for providing a sealing engagement between the enclosure and the ring member. The ring member provides the rotation required for proper attachment of the container assembly to the RTP without any requirement for rotation of the enclosure.

A flexible container is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments, separated by peelable seals, in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The seals are constructed to provide a non-linear resistance characteristic to hydraulic pressure, which causes the seal to peel open completely along its length. The container is folded-over along the line of one of the seals and also includes a locking tab and retaining slot to secure the bag in a folded-over condition.
