A sheath is provided with a stationary deflector disposed on the path of the slider so that contact between the slider and the deflector causes the slider to be inclined and consequently causes the needle to be inclined inside the sheath. A return mechanism is provided so as to push the inclined slider back in the opposite direction so that the point of the inclined need is prevented from moving. This disposition ensures that the needle cannot escape from the sheath after it has been used.

A device for installing a catheter tube in a vein by the Seldinger method, once the device has been inserted, has a tubular cylindrical sheath, with a slot running its entire length, mounted on a dilator tube. A cylindrical main portion of the sheath terminates at a distal end edge which flares forwardly and is adjacent a shoulder of the dilator tube for enabling the dilator tube to be withdrawn through the sheath.

A hub (,) of an arterial puncture needle includes a tubular and transparent viewing chamber (,) accessible to the reflux of blood, and a reserve chamber (,) which is leaktight to the ambient air and in air communication with an outlet end (,) of the viewing chamber. The two chambers form a rigid unit with the hub and have predetermined volumes such that the blood does not reach the air reserve chamber when the systolic pressure is maximal.

The invention relates to strips of cocks. The strip is constituted by plates and by cocks, each plate being provided on two opposite edges with fastening portions enabling the plates to be fixed together end-to-end, and each plate carrying on at least one face one or more cocks or being provided on said face with means to which one or more cocks can be mounted, and each cock comprising a plug to which at least three endpieces secured to said plug open out, two of the endpieces, respectively a male endpiece and a female endpiece, being in alignment and opposite to each other on an axis that is perpendicular to said opposite edges of the plate once the cock is fixed on the plate, and the third endpiece being disposed obliquely or perpendicularly relative to the two aligned endpieces, said cock being designed to control fluid communication between the aligned endpieces and the third endpiece, and said aligned endpieces being designed so that said male and female endpieces engage mutually from cock to cock when the plates carrying the cocks are connected together end-to-end. The invention is particularly applicable to strips of cocks for medical use.
