Abstract
A seal septum structure includes a septum body structure fabricated of a resilient material. The body structure includes an opening formed there through and a first seal surface circumscribing the opening to engage against a needle when inserted into the opening. The body structure further includes a second seal surface for engaging against a stopper structure when the needle is not inserted into the opening. The septum structure can be over-molded on a rigid host part, or fabricated as a separate structure from the host part, and pressed in to place.
Claims47
A glandular seal septum, comprising:
- a septum body structure fabricated of a resilient material;
- the body structure including an opening formed there through and a gland seal surface circumscribing the opening, the gland seal surface sized to engage against a needle when inserted into the opening;
- the body structure further including a stopper seal surface for engaging against a stopper structure when the needle is not inserted into the opening.
A fluid interconnect, comprising:
- an interconnect body structure having an fluid interconnect port;
- a needle for connection to a fluid reservoir or fluid path;
- a movable stopper structure;
- a septum body structure fabricated of a resilient material and fitted into the fluid interconnect port;
- the septum body structure including an opening formed there through and a gland seal surface circumscribing the opening, the gland seal surface sized to engage against the needle when inserted into the opening;
- the septum body structure further including a stopper seal surface for engaging against the stopper structure when the needle is not inserted into the opening.
A fluid interconnect structure, comprising:
- a rigid interconnect body structure having an fluid interconnect port;
- a septum body structure fabricated of a resilient material and over-molded onto the fluid interconnect port;
- the septum body structure defining a first seal surface to engage against a needle when inserted into the opening;
- the septum body structure further including a second seal surface for engaging against a fluid interconnect stopper structure when the needle is not inserted into the opening.
A ganged fluid interconnect structure, comprising:
- a rigid interconnect body structure defining a plurality of fluid interconnect ports;
- a septa body structure fabricated of a resilient material and over-molded onto each of the fluid interconnect ports;
- the septum body structure defining a plurality of septa, each septum including a first seal surface to engage against a needle when inserted into the opening and a second seal surface for engaging against a fluid interconnect stopper structure when the needle is not inserted into the opening.
