Patents by Inventor Daniel L. Robinson

Daniel L. Robinson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6117285
    Abstract: An apparatus for electrolyzing fluids. The resulting electrolyzed fluids are particularly suited for treating physiological materials such as whole blood, plasma, or cell isolates in order to reduce the effect of harmful microorganisms. A container holds the fluid and a power supply provides a source of electrical current to an anode and a cathode positioned within the container. The system is particularly suited for disinfecting and/or sterilizing health care instruments. The instruments are bathed in the electrolyzed saline solution. If the instrument includes internal conduits the system of the present invention also preferably flows the electrolyzed saline solution through such conduits also to provide both cleaning and sterilization. The electrolyzed saline solution is recirculated from the electrodes to the instrument being sterilized. Embodiments of the invention are particularly suited to sterilizing dental drill handpieces without damage to the handpieces.

  • Patent number: 6007686
    Abstract: An apparatus for electrolyzing fluids is disclosed. The resulting electrolyzed fluids are particularly suited for treating physiological materials such as whole blood, plasma, or cell isolates in order to reduce the effect of harmful microorganisms. A container holds the fluid and a power supply provides a source of electrical current to an anode and a cathode positioned within the container. The anode and cathode each comprise a cylindrical shape. The cathode is positioned concentrically in relation to the anode. The spacing between the cathode and the anode is not greater than a preferred amount. Moreover, the voltage potential between the cathode and the anode is not greater than a preferred amount. Also described is a system for disinfecting and/or sterilizing health care instruments. The instruments are bathed in the electrolyzed saline solution.

  • Patent number: 5560816
    Abstract: An apparatus for electrolyzing fluids is disclosed. The resulting electrolyzed fluids are particularly suited for treating physiological materials such as whole blood, plasma, or cell isolates in order to reduce the effect of harmful microorganisms. A container holds the fluid and a power supply provides a source of electrical current to an anode and a cathode positioned within the container. The anode comprises a base material selected from titanium and niobium. An outer layer of platinum is bonded to the base. The anode comprises a cylindrical shape. The cathode is also connected to the power supply and comprises titanium and has a substantially cylindrical shape. The cathode is positioned concentrically in relation to the anode. The spacing between the cathode and the anode is not greater than a preferred amount. Moreover, the voltage potential between the cathode and the anode is not greater than a preferred amount.
