A medical coupling for a cannula or the like includes a female member (1) with a body providing a hub (4) defining a socket (11), a valve section (5) with a valve actuator (15) slidable on the body, and a finger gripping section, and a male member (2) including a spigot (20) for engagement in the socket (11), a cap (21) with a screw thread for engagement with a flange (9) of the hub (4), an internally splined sleeve (24) and a finger gripping section (22). When the spigot (20) is inserted into the socket (11), the cap (21) is rotated onto the flange (10) to hold them against being pulled apart, and the valve actuator is displaced to open the valve and to bring a splined collar (19) into locking engagement with the sleeve (24). A separate casing (30) is provided to form sealed housing around the coupled parts of the male and female members between their griping sections (6, 22).
A coupling for a medical cannula or the like comprising a female member (1) having a socket (11), a male member (2) having a spigot (20) engagable with a push fit into the socket (11), a cap (21) attached to one member and rotationally engagable with the other member to secure the spigot against disengagement from the socket, and a locking engagement to lock the cap (21) against rotation in the direction of disengagement from said other member, wherein the locking arrangement comprises a sleeve (24) provided on the cap and a slide (19) movably mounted on said other member, the slide (19) being movable on the other member after the spigot has been secured against disengagement from the socket (11) by rotational engagement of the cap (21) with the other member so as to engage the slide (19) with the sleeve and thereby lock the sleeve and cap against rotation in a disengagement direction.
A coupling for a medical cannula or the like comprising a female member (1) having a socket (11), and a male member (2) having a spigot engageable with a push fit into the socket (11), a cap (21) attached to one member and rotationally engageable with the other member to secure the spigot against disengagement from the socket, wherein the male and female members have finger gripping sections (6,22) at which the members are intended to be held during engagement of the spigot in the socket and engagement for the securing cap (12), and a casing is provided to define a sealed housing around the socket, spigot and cap of the male and female members when coupled together, with the gripping sections (6,22) remaining outside the housing.
