Abstract: An evacuated suction bottle 1 for wound drainage, which comprises two chambers 2, 3 separated from one another, is described.

Abstract: Puncturing and catheterizing device for the human or animal body with a metallic puncture needle and a cannula which surrounds the puncture needle in the region between its point and rear end and through which, after the puncture needle has been pulled out, a longer guide-wire can be inserted into the body, which then, after the cannula has also been pulled out, serves as a guide for a catheter to be inserted. The puncture needle 3 is electrically conductive from its point 1 to its end projecting out of the cannula 9 and is equipped with an electrical connecting piece 5 at the rear end (FIG. 1 ).

Abstract: An elongated medical instrument for the examination or treatment of body cavities, in particular endoscopes, with a device to assist introduction by the principle of the tubular structure which becomes everted is described, which instrument comprises the device to assist introduction 1 being composed of a pipe 2 which is open at both ends and has pressure connectors 3 on the sides, and is composed of a flexible, eversible tubular structure 4 running through the pipe 2, the two ends 5, 6 of the tubular structure each being connected to one end 7, 8 of the pipe 2, the medical instrument 9 running through the pipe 2 inside the tubular structure 4, and the tubular structure 4 being folded in several double-layers in the region 10 of the distal end 11 of the medical instrument 9.

Abstract: A novel catheter with a guide wire, the tip of which is bent in the manner of a walking stick, enables central veins to be rapidly and safely catheterized via a peripheral approach.
