Abstract: A foot operated traction device for allowing a pregnant woman to selectively self-induce dilatation of her cervix via her foot and a method for doing the same, the device comprising a balloon catheter comprising an inflatable balloon insertable above the cervix of the pregnant woman and an elongate catheter tube comprising a catheter tube proximal end portion and a catheter tube distal end portion coaxially mounted to the inflatable balloon, the inflatable balloon inflatable with a fluid to apply dilatative pressure against the cervix, and an elongate stirrup connected to the catheter tube at the catheter tube proximal end at a stirrup proximal end and removably engageable with the foot of the pregnant woman at a stirrup distal end, wherein the stirrup distal end is movable by the movement of the foot to selectively vary a traction force of the inflatable balloon.

Abstract: Assembly with connectable and disconnectable elements comprises a flexible bag containing liquid solution with a first valve connector, at least one vial with active substance and provided with a hermetic closing cap, a coupling and piercing device couplable to the cap of the vial and an adapter between the first connector and the coupling and piercing device. The adapter has a hollow external body with a first end fixable by screwing to the first connector, an axially bored, coaxial internal stem, the screwing causes the opening of the first connector and a second end including a second valve connector fixable to the coupling and piercing device and is screwable in the external body so that internal stem causes the opening of the second valve connector.

Abstract: A negative pressure wound therapy device that includes a first tubing connectable in flow communication with a source of negative pressure configured for application of negative pressure to a wound site, a second tubing in flow communication with the wound site, and a valve.
