Universal device for the thorough cleaning, disinfecting and sterilizing of dental, surgical, and veterinary instruments as well as for other uses

A device for the thorough external and internal cleaning and sterilizing of dental, surgical and veterinary instruments, comprising a chamber having a downward tapering, frusto-conical shape with an external wall, an internal wall, separated by a hollow space with holes on the internal wall through which fluids, liquids, and/or air are sprayed in a pre-set sequence on to the instrument to be sterilized, arranged vertically inside the chamber, the hollow space being subdivided along a vertical axis of the chamber into smaller chambers, each of said smaller chambers having a number of said holes with jets, said holes being inclined at a downward angle passing off-center at a specific distance from the vertical axis of the chamber;

• the shape of the chamber and the pressure upstream of the holes and/or their diameter, as well as their direction, being selected so as to cause the jets to rotate in a swirling movement with increasing speed and kinetic energy downwards from the top of the chamber;
• and a pierceable membrane disposed at a mouth of the chamber in order to prevent contamination of the instrument.
