Abstract
An apparatus for disinfecting surfaces and in particular human and animal wounds, includes a contractor for accumulating concentrated ozonated water and systems to deliver ozonated water from the reservoir to a nozzle having one or more jets for delivering a spray of ozonated water on to the surface to be treated. The nozzle has an encircling shroud and systems are provided for withdrawing ozonated gas liberated at the nozzle from around the nozzle. A collection tray is provided which is located under the surface/wound to be treated to receive ozonated water flowing from the treatment region and where any residual ozone is broken down.
Claims31
An apparatus for producing a spray of ozonated water for disinfecting a surface comprising a reservoir for accumulating ozonated water, means to deliver ozonated water from the reservoir to a nozzle having one or more jets for delivering a spray of ozonated water onto the surface to be treated, and an encircling shroud as a means to provide for the withdrawal of ozonated gas liberated at the nozzle from around the nozzle, means to circulate a flow of water from the reservoir through an ozonating station and to the reservoir, means to supply ozone to the ozonating station to be dissolved in the flow of circulating liquid returning to the reservoir to enable the ozone concentration in the water to be raised to a requisite level prior to delivery of the ozonated water to the spray nozzle for application to the surface to be treated.
An apparatus as claimed in any of the preceding claims, wherein the reservoir has means for measuring the dissolved ozone concentration and/or the oxidation reduction potential of the fluid;
- means for applying said fluid.
An apparatus as claimed in any of the preceding claims, wherein the fluid enters and exits the reaction vessel through the same orifice.
An apparatus as claimed in any of the preceding claims, wherein any undissolved gas in the reservoir is captured and passed through a destruct device.
An apparatus as claimed in any of the preceding claims, wherein means are provided to apply negative pressure around the region where the reaction fluid is sprayed onto a surface.
An apparatus as claimed in any of the preceding claims, wherein a device is provided for supporting a patient's appendage to be treated and collecting fluid sprayed onto a wound on the appendage, the reaction fluid is sprayed onto a wound and is subsequently collected in a device, onto or into which the patients' appendage is placed.
An apparatus as claimed in any of the preceding claims, wherein the equipment is portable.
An apparatus for applying an aqueous ozonated fluid produced within a reservoir to a surface and more preferentially a wound, comprising:
- a) a conduit for conducting the fluid from the reservoir to the surface
- b) a spray head for spraying the fluid onto the surface
- c) a shroud
- d) and a means of producing a negative pressure around the spray head.
An apparatus for collecting the fluid once it has been applied to a wound, comprising:
- a) a catchment device
- b) a means of conducting the fluid from the catchment device to the main unit.
- c) means for conducting ozone gas from the catchment device to the main unit.
