Abstract
A cap for coupling to a medical adapter may include a housing with a closed top end and an open bottom end with legs that extend from the housing away from the bottom end. Members may extend from an inner surface of the legs to engage and secure the cap to a medical adapter or an insert configured to mate with a medical adapter. A cap may include angular ridges between a cap housing and an insert to permit rotation of the cap in single direction and prevent removal of the cap from a medical adapter. A cap may include hinged legs to permit the cap to be secured to a medical adapter by rotating the legs toward each other until a portion of a collar on each leg may be matingly joined around the medical adapter.
Claims20
A tamper-resistant cap for a medical adapter, the tamper-resistant cap comprising:
- a housing having a closed top end, an opposing open bottom end, a side wall between the top end and the bottom end, and a plurality of legs, the housing defining an axis extending between the top end and the bottom end, and at least one leg of the plurality of legs comprising a member extending radially inward from an inner surface of the at least one leg;
- and
- an insert comprising a first end and an opposing second end, the first end forming a cavity, wherein the insert is positioned within the housing between an inner surface of the top end of the housing and the member of the at least one leg, such that insert is movable a distance between the inner surface of the top end of the housing and the member of the at least one leg, and the inner surface of the top end of the housing and the second end of the insert are configured to engage against each other to rotate together in a first direction and to disengage from each other when any of the housing and the insert are rotated in an second direction that is opposite to the first direction.
A tamper-resistant cap for a medical adapter, the tamper-resistant cap comprising:
- a housing having a top end, a bottom end, and a plurality of legs, and at least one leg of the plurality of legs comprising a member extending radially inward from an inner surface of the at least one leg;
- and
- an insert comprising a first end, an opposing second end, and a cavity extending through the first end, the insert positioned between the inner surface of each leg of the plurality of legs, and between the top end and the member of the at least one leg of the plurality of legs;
- wherein the second end of the insert is configured to engage against the inner surface of the top end of the housing such that the housing and the insert are rotatable together in first direction when the insert is moved toward the top end of the housing, and the second end of the insert is configured to move away and disengage from the inner surface of the top end of the housing when the insert is rotated in a second direction that is an opposite to the first direction such that the insert is moved toward the bottom end of the housing.
