Abstract: The device for cleaning at least one medical hearing unit includes an earpiece, and a space for receiving the earpiece, the space having at least one seat receiving the earpiece and an orifice with a cavity underneath. There is a circulator for a liquid within the space to contact the earpiece. The cavity includes an outlet for flow or aspiration of liquid, an opening opposite, and, below each orifice, a directing device to guide the liquid towards and under each orifice, as far as the outlet, in such a way that liquid flows across the earpiece.

Abstract: The present invention relates to a device (2) for cleaning at least one medical hearing unit comprising an earpiece (101), said device (2) comprising a space (3) for receiving said earpiece (101), said space (3) comprising at least one seat (4) designed in such a way as to receive said earpiece and comprising, in the lower part, an orifice (11designed such that the distal end of said earpiece extends inside a cavity (12) formed underneath, and means (9) for causing a liquid to circulate within said space (3) in such a way that said liquid comes into contact with said earpiece, characterized in that said cavity (12) comprises at least one outlet (15) for flow or aspiration of said liquid, opening out opposite and below each orifice (11), and in that the bottom of said cavity (12) comprises means (14) for directing said liquid towards and under said orifice (11), as far as said outlet (15), in such a way that said liquid flows across said earpiece, in particular its standard or made-to-measure ear mold.

Abstract: There is disclosed a new calcium-regulated promoter to be used for increasing production of extracellular enzymes, or heterologous polypeptide, a recombinant vector that includes the DNA sequence of the promoter operatively linked to a DNA encoding said enzyme or polypeptide and a host organism transformed with the recombinant vector that includes the promoter operatively linked to the DNA encoding said enzyme or polypeptide. The present invention further relates to Streptomyces expression systems and methods for expressing foreign DNA sequences in Streptomyces and for secreting to the surrounding medium polypeptides and proteins coded for by those foreign DNA sequences.
