Abstract
A self-sealing subcutaneous injection site for implantation in the body includes a housing having a bottom wall and a generally resilient dome-shaped wall which defines an interior chamber within the housing. The interior chamber has a durometer and shape for providing compressive forces within the dome-shaped wall for sealing punctures extending through the dome-shaped wall upon fluid pressurization of the interior chamber. A conduit extends through the dome-shaped wall into the interior chamber to provide a fluid-flow passageway to the chamber.
Claims11
A self-sealing subcutaneous injection site comprising:
- a housing having a bottom wall and a resilient, generally dome-shaped wall defining an interior chamber, which interior chamber has a convex upper wall formed by a portion of the dome-shaped wall for providing compressive forces within such upper wall for sealing punctures through the upper wall upon fluid pressurization of such interior chamber;
- and
- a conduit extending through the dome-shaped wall into the interior chamber for providing a fluid-flow passageway to the interior chamber.
