Abstract: A medical fluid flowline connector comprised of axially aligned relatively rotatable parts preferably comprising a male Luer and a female Luer and an axially compressed elastomeric valve element therebetween includes an elastomeric swabbable stopper permanently positioned in the female Luer, the stopper having a head urged by spring force outwardly of the female Luer when the spring is compressed and also being retained therein by the spring. The spring may comprise an axially compressible resilient portion of the stopper or it may comprise a separate compressible element.

Abstract: A protective sleeve and adaptor hub combination for retrofitting conventional medical syringes so that the syringe needle may be completely enclosed in the protective sleeve following use of the syringe. The protective sleeve is typically made of polypropylene plastic whereas the adaptor hub which fits in the protective sleeve is made of a harder material Such as polycarbonate. The adaptor hub has internal male threads of hardness suitable for penetrating and cutting female thread grooves in the relatively soft material of a nozzle end of a medical syringe during relative rotation of the protective sleeve and adaptor hub combination and the syringe. Once connected, the hub and sleeve cannot be removed from the syringe. The protective sleeve also has internal spiral tracks and the hub has external follower projections engaged in the tracks for guiding movement of the adaptor hub in the protective sleeve.

Abstract: A retractable blood collection device having a housing comprised of relatively rotatable parts and a hub in the housing supporting a double ended cannula which is retracted by spring pressure into the housing when the housing parts are rotated to contain the used cannula in the housing for safe disposal.

Abstract: A needle-less three part medical fluid flowline connector comprised of a relatively rotatable male Luer housing and a female Luer valve actuator includes a compressed elastomeric valve element having a fluid passageway therein which extends from an axially aligned end on one side of the valve element to an off-center positioned end on the other side of the valve element and avoids the use of a cannula and septum which is pierced during valve opening. Rotation of the compressible valve element with respect to the housing in which it is seated is prevented by interengaged fingers and grooves on the housing and valve element. Withdrawal of the valve actuator from the housing is prevented by a abutting radially extending surfaces and an annular bulge and groove on the actuator and housing respectively. An interengageable longitudinally extending finger and diametrically spaced grooves on the actuator and housing enable the user to readily position the valve in an open or closed position.
