A needleless connector comprising:
- a housing having an internal cavity with an interior surface, a port, an output flow channel, and a fluid flow path through the cavity between the port and the output flow channel;
- and
- a collapsible valve disposed within the cavity, the valve comprising:
- one or more rings each having a respective surface in sealing contact with the interior surface of the housing;
- and
- a notch formed in each of the one or more rings, each notch circumferentially offset from a notch in an adjacent ring,
- wherein the fluid flow path passes the one or more rings through the respective notch.
A needleless connector comprising:
- a housing having an internal cavity with an interior surface, a port, an output flow channel, and a fluid flow path through the cavity between the port and the output flow channel;
- and
- a collapsible valve disposed within the cavity, the valve comprising two discontinuous rings, each ring having a respective surface in sealing contact with the interior surface of the housing and a discontinuity portion, through which the fluid flow path passes each ring;
- wherein the discontinuity portions of the two rings are circumferentially offset.
