  • Patent number: 6322546
    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.

  • Patent number: 6241711
    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.

  • Patent number: 6206861
    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.
