Abstract: A device for treating sheet-like material using water jets/needles. The device comprises a pressurize water supply body consisting of a feed chamber extending along the entire length of the body and inside which pressurized water is guided through a filter, and a distribution area distributing pressurized water along the entire length of treatment. The distribution area includes a plate (7) which is provided with microperforations, whereby the holes thereof define water needles which are directed against the surface of the material which is to be treated. The invention is characterized in that the microperforations (15) are provided inside inserts (13) which are made of a hard material. The inserts are set inside pre-made hoes (12) in the plate.

Abstract: A medical instrument (1) comprises a tampon-like section (2) for introduction into a body cavity. The section (2) has an inner part (3), a first cuff (4) surrounding the inner part (3) and a second cuff (5) surrounding at least parts of the first cuff (4) which is permeable for application medium. A medical instrument was produced to stop body fluids from discharge, to stop bleeding and administer application media.

Abstract: A mechanism for the treatment of materials by pressurized water jets includes a body (1) for supplying water under pressure which includes a feeding chamber (2) extending over the whole length of the body, and wherein water under pressure is fed to the feeding chamber through a filter (4). The body also includes a distributing zone for distributing water under pressure over a whole treatment length against a plate (7) provided with micro-perforations which define water needles (8) directed against the surface (S) of the material to be treated. The material is supported by a carriage element subjected to a suction source eliminating the treatment water.
