Abstract

Under electronic monitoring and control, fluids flow into a fluid diffusion device to form a fluid combination. The fluid combination has corrosive properties as it flows into an antimicrobial canister housing an insert with antimicrobial metallic coated media and associated support. The fluid combination corrodes the antimicrobial metallic coated media located inside the antimicrobial canister. Upon exiting the antimicrobial canister, the fluid combination contains dissolved metal ions and is a liquid antimicrobial agent. Monitors throughout the system ensure the antimicrobial agent is being produced at the desired level and rate as it exits into its application.

Claims

1. An antimicrobial device comprising:

a housing having an inlet and outlet for a turbulated fluid;

an insert contained in the housing, said insert containing a media impregnated with metal for production of antimicrobial metallic ions;

a fluid diffusion device connected upstream of the housing inlet and having fluid inlets for a first fluid and a second fluid, said first and second fluid combined in the fluid diffusion device as the turbulated fluid ; and

,

means for controlling flow of the first and second fluids received by the fluid diffusion device for varying concentration of metallic ions entrained in the turbulated fluid.

2. The antimicrobial device defined in claim 1 wherein the housing is a cylindrical canister and the insert comprises a metallic coated substrate, support frame and porous body helically rolled within the canister.

3. The antimicrobial device defined in claim 2 further comprising fasteners inserted into the helically rolled insert to provide a constant flow cross section in each layer of the helically rolled insert.

4. The antimicrobial device defined in claim 1 wherein the housing is a cylindrical canister and the insert comprises a plurality of disks, each disk containing a media impregnated with metal for production of antimicrobial metallic ions.

5. The antimicrobial device defined in claim 4 wherein the media comprises resin balls.

6. The antimicrobial device defined in claim 4 wherein the media comprises a metallic impregnated substrate shredded into a confetti.

7. The antimicrobial device defined in claim 4 wherein the media comprises a metallic wool.

8. The antimicrobial device defined in claim 4 wherein the media comprises a metallic salt.

9. The antimicrobial device defined in claim 1 wherein the insert provides a gradient of impregnated metal for generation of antimicrobial metallic ions between the housing inlet and housing outlet.

10. The antimicrobial device defined in claim 9 wherein the gradient is determined by an ion uptake rate.

11. The antimicrobial device defined in claim 9 wherein the insert comprises a metallic coated substrate, support frame and porous body helically rolled, said metallic coated substrate having layers of predetermined length to provide said gradient.

12. The antimicrobial device defined in claim 9 wherein the insert comprises a plurality of disks, said disks stacked in adjacent engagement and each disk contains a predetermined amount of a media impregnated with metal for production of antimicrobial metallic ions, each adjacent disk containing a greater amount of media to achieve the desired gradient.

13. The antimicrobial device defined in claim 12 wherein the media is selected from the set of resin balls, metallic impregnated substrate shredded into confetti, a metallic wool or a metallic salt.

14. The antimicrobial device defined in claim 1 wherein the housing is cylindrical canister and further comprising a flow distribution puck.

15. The antimicrobial device defined in claim 14 wherein the flow distribution puck is perforated.

16. The antimicrobial device defined in claim 14 wherein the flow distribution puck is porous.

17. The antimicrobial device as defined in claim 1 wherein the metallic coating of the substrate is silver.

18. The antimicrobial device defined in claim 1 wherein the first fluid is water and the second fluid is air the means for controlling comprises:

a fluid pressure regulator connected to the fluid diffusion device water inlet,

an air pressure regulator connected to the fluid diffusion device air inlet; and

a flow reducer connected to the outlet of the housing.

19. The antimicrobial device defined in claim 18 further comprising:

a solenoid fluid shut off valve connected upstream of the fluid pressure regulator;

a temperature sensor for incoming water;

a fluid pressure sensor for incoming water;

an air pressure sensor for incoming air;

a solenoid air shut off valve connected upstream of the air pressure regulator; and

a flow sensor connected downstream of the flow reducer.

20. The antimicrobial device defined in claim 19 further comprising:

an electronic module connected to the temperature sensor, fluid pressure sensor, air pressure sensor and flow sensor for data input, said electronic module having a controller adapted for operation of at least the solenoid fluid shut off valve and solenoid air shut off valve responsive to the data input.
