  • Publication number: 20210060327
    Abstract: A percutaneous access device comprises a frame, a hatch and a hinge that couples the frame to the hatch. The frame has a passageway that extends therethrough. When the percutaneous access device is implanted in a patient, the frame is positioned beneath a layer of skin of the patient against a bodily vessel. Moreover, the hinge biases the hatch closed against the frame in a normally closed position such that liquid flowing through a lumen of the vessel cannot escape through the percutaneous access device. However, the application of force against the hatch from an object (such as a needle) that extends through the passageway causes the hatch to open outwardly from the frame and into the lumen of the vessel. Correspondingly, the hinge biases the hatch back to the normally closed position upon removal of the object.

  • Patent number: 5507133
    Abstract: A unique package for inoculants and a method for enabling the end user to introduce a pure culture of a microorganism into its appropriate growth substance, and later the microorganism enriched substance into a carrier material within a self-contained unit. The basic package separates a stabilized pure culture of the microorganism from the growth substance by a clamp which forms a physical partition. The microorganism is introduced to the substance when the partition is eliminated. After a time of growth to a maximum extent possible in the substance, the package is fractured to release the fresh inoculation at maximum microorganism vitality. Growth of the microorganism in the growth substance in-situ results in maximum numbers of the beneficial microorganism being available at the site of application.
