Abstract

A medical and surgical instrument cleaning and disinfecting device consisting of a tubular body whose one end is open and whose other end is equipped with a liquid collection tank is shown. The detector senses the presence of an instrument inside of the tubular body and controls pressurized diffusion of a nebulized disinfection product which is sprayed on the instrument. A suction device pulls disinfection spray towards a reservoir.

Claims

1. A device for cleaning and disinfecting medical and surgical instruments with a neublized disinfection fluid, comprising in combination:

a horizontally disposed tubular body having a first open end and a second end connected to a liquid collection tank;

said tubular body having a condensation means for promotion of condensation of nebulized disinfection fluid;

a suction means connected to said device for drawing air and nebulized disinfection fluid through said condensation means such that condensation of the fluid occurs;

detecting means for detecting the presence of an instrument inside said tubular body, said detecting means located near the open end of said tubular body;

diffusion means for pressurized diffusion of nebulized disinfection fluid, responsive to detection by said detecting means; and

wherein said tubular body comprises an inside wall inclined downward from the open end to the second end connected to the tank.

2. The device according to claim 1, wherein said diffusion means consists of a plurality of injectors, regularly distributed on an inside periphery of said tubular body, each injector comprising a mixing chamber in which air is brought to a center portion thereof and the disinfecting product is brought in peripherally.

3. The device according to claim 1, wherein said tubular body further comprises:

a first tubular part, located at the open end of said tubular body, containing said detection means and said diffusion means; and

a second tubular part located between said first tubular part and said collection tank, having one end removably mounted on said first tubular part, and having said collection tank which is removably mounted on said second end.

4. The device according to claim 2, wherein said injectors and said detecting means are not located on the lower portion of said tubular body.

5. The device according to claim 4, wherein said detecting means are located, on said tubular body, upstream from said diffusion means in the direction of the introduction of an instrument into the tubular body.

6. The device according to claim 1, further comprising means for detection of the presence of a practitioner'"'"'s hand holding an instrument to be cleaned on a front face of said tubular body.

7. The device according to claim 1, wherein said tubular body is adapted to be connected to said liquid collection tank and said suction means is connected near said tubular body second end.

8. The device according to claim 7, wherein said condensation means has a system of baffles.

9. A device for cleaning and disinfecting medical and surgical instruments with a nebulized disinfection fluid comprising in combination:

a tubular body having first and second openings, and having said first opening higher than said second opening;

wherein said tubular body has its lowest surface inclined downward to said second opening with respect to a horizontal plane;

said tubular body having a condensation means for promotion of condensation of nebulized disinfection fluid;

a reservoir connected to said tubular body second opening;

a suction means connected to said device for drawing air and nebulized disinfection fluid through said condensation means such that condensation of the fluid occurs;

means for detecting the presence of an instrument in said tubular body; and

means for spraying disinfection fluid responsive to said means for detecting wherein said means for spraying is operative when said means for detecting detects a medical instrument.

10. The device in accordance with claim 9 wherein said inclination of said tubular body lower surface provides for gravity drainage of condensed fluid particles.

11. The device in accordance with claim 9 wherein said suction means prevents escape of any nebulized disinfecting fluid.

12. The device of claim 9 wherein said condensation means comprises a series of baffles which allow condensation, and which do not contact the lowermost portion of said body in order to allow flow of condensate along the lowermost portion of the tubular body.
