Patent ID: 8343112

Claim:
A cap configured to disinfect a medical connector, the cap comprising: an outer housing that defines a proximal end, a distal end, and a cavity that extends from the proximal end toward the distal end; and an inner housing disposed within the outer housing, the inner housing comprising a connection interface that is configured to connect the inner housing to a medical connector, the inner housing defining a chamber having therein an antiseptic, a sealing member and a first biasing member, wherein the sealing member is configured to form a seal with a portion of a medical connector that is inserted into the chamber, and wherein the first biasing member is configured to urge the sealing member in a proximal direction toward an open end of the chamber; a second biasing member that is coupled with each of the outer and inner housings, wherein the second biasing member is configured to bias the inner housing toward the extended position: wherein the cap is configured to transition from a pre-use state, in which the inner housing is in a retracted position relative to the outer housing, to a connection-ready state, in which the inner housing is in an extended position relative to the outer housing, wherein the retracted position of the inner housing is closer to the distal end of the outer housing than is the extended position.
