Abstract: A design and method of operation are disclosed for a fluid control conduit of a blood reservoir. The venous blood inflow conduit includes a fluid control nozzle and a base. When assembled together the nozzle and base form a trap feature which prevents reflux of air or other gas upwardly into the nozzle of the conduit. As a result, during use of the reservoir the conduit normally runs full of venous blood and turbulence of the blood is prevented. In addition, the conduit also functions to divert the downward flowing venous blood in the nozzle into the base at an optimum fluid velocity to overcome the buoyancy effect of air or gas bubbles within the blood.
Abstract: A new eye and wound washing device for irrigating eyes and wounds with fluids such as water or saline solutions. The inventive device includes a hollow tube member with at least one elongate arm tube portion extending from the proximal end of an elongate stem tube portion. The distal end of the stem tube portion has an opening into the hollow interior of the tube member and is connectable to a fluid reservoir to permit fluid flow from the fluid reservoir through the distal end opening into the hollow interior of the tube member. A first irrigator member is in fluid communication with the first arm tube portion and includes a plurality of irrigation apertures for permitting fluid flow therethrough from the interior of the tube member. The mounting portion of a first guide member is mounted to the first arm tube portion. The first guide member also includes an arcuate finger guide portion extending from the mounting portion.
Abstract: A face masque that applies cooling therapy to facial features of a patient. The masque is formed of two nylon or plastic layers that define a closed interior space and filled with a cooling medium that includes water, glycerin and hydroxyethyl cellulose. The masque controls the rate of heat dissipation from a user based upon the heat capacity, mass, rheology and composition of the materials used. The masque is lighter than conventional water-filled ice packs. It remains unfrozen and malleable even when cooled to sub-zero temperatures at which water-filled packs would freeze solid. The masque readily conforms to facial features due to the materials used, thereby contributing to improved comfort on the part of a user. Further, the masque possesses improved cooling therapy because it remains cold for longer periods of time relative to water-filled ice packs. Optionally, the masque accommodates eye inserts placed between a main body of the masque and recesses of the patient's eyes.

Abstract: A progressive filtration system for a chest drainage unit during continuous autotransfusion that allows the user to clear the fluid pathway of blood clots and trapped air that form after filtration in a flushing action initiated by the user. The filtration system comprises a gross filter for filtering incoming blood at the inlet portion of a collection chamber of a chest drainage unit and a fine filter assembly located at the bottom portion of the collection chamber for refiltering collected blood prior to reinfusion of that blood back to the patient. The filter assembly includes a valve cap at the top portion of the assembly that functions as a one way valve that permits reflux of later developing blood clots that might clog the tubing once the blood has already passed through the assembly. The valve cap is also adapted for sealing engagement with a drop tube that places the filter assembly in fluid flow communication with an outlet of the collection chamber located at the top portion of the chamber.
Abstract: A method and apparatus for attaching a connector assembly onto a vial is disclosed. The connector assembly features a protective cap, a collar attachable to the rim of the vial, and a locking ring disposed about the collar. A vial access device is contained within the collar. One or more ribs are provided adjacent a distal portion of the collar to seal against the stopper obturating the vial. The collar is provided with one or more slits which render the collar flexible in directions radial and axial to the central axis of the vial to compensate for variations in tolerances or dimensions present in the various components. Locking structure between the locking ring and the collar assures that the collar remains fixed to the vial.
Abstract: A combined arterial-venous blood flow set comprises connected lengths of flexible tubing for receiving blood from a patient, for conveying the blood to a blood processing device such as a dialyzer or an LDL filter, and for returning the blood to the patient. An optional first bubble trap chamber is connected in series flow between two of the lengths of tubing at a flow position downstream from the patient and upstream from the blood processing device. A second bubble trap chamber is connected in series flow between two of the lengths of tubing at a flow position downstream from the blood processing device and upstream from the patient. A first portion of the tubing which is in a flow position upstream from the blood processing device extends by the second bubble trap chamber, and is physically, laterally connected to it without direct flow connection. This helps to stabilize the positioning of components of the flow set and to reduce confusion in set-up and priming.
Abstract: A needleless injection site comprising a housing which defines a fluid passage. Disposed within the housing is a reseal member which includes an openable and closable aperture, and an expandable and collapsible reservoir. The reseal member normally resides in a first position within the housing wherein the aperture is closed and the reservoir is collapsed. The reseal member is deformable such that the application of compressive pressure thereto will facilitate the movement thereof within the housing to a second position wherein the reservoir is expanded and the aperture is opened and placed into communication with the fluid passage and the reservoir. The removal of the compressive pressure from the reseal member will facilitate the resilient return thereof to the first position wherein the aperture is closed and the reservoir is collapsed. The collapse of the reservoir is adapted to prevent the creation of a vacuum within the fluid passage when the reseal member resiliently returns to the first position.
Abstract: A Liquid/gas drop (Lg drop) intended to be used as an eye drop. The Lg drop has the form of a cluster of contiguous bubbles, and numerous constituent bubbles are volumetrically similar. Each constituent bubble encloses a gas. The cluster is formed of one thin continuous liquid wall. A device for manufacturing the Lg drop includes a flexible bottle used to inject a gas into a chamber, and a flexible bottle used to inject a bubble forming liquid into the chamber. The chamber has an outlet which is used to induce an accumulation of bubbles. This accumulation forms the Lg drop. A method of making the Lg drop includes manufacturing volumetrically similar bubbles, and inducing an accumulation of the bubbles. The accumulation obtains a particular total mass causing the Lg drop to fall from the device.
Abstract: 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.
