Definitions

  • This invention relates to an ozone based sanitizer, and more particularly to a sanitization device having a sealable enclosure that can be filled with ozone to sanitize the contents contained therein.
  • Ozone is known to kill pathogens quickly by processes that are not completely characterized for each pathogen. However, it is known that ozone can kill or deactivate all transient flora and pathogens, including all spores and possibly prions.
  • Kowalski describes in vitro experiments on rates of deactivation of bacterial cultures grown on the agar surface of petri dishes that have been ozonated.
  • Colony forming units (CFUs) on control petri dishes are compared to those on ozonated petri dishes to obtain survival fractions as a function of exposure times (e.g., 'death curve'), which is a standard in vitro time/kill-efficacy study technique.
  • 'death curve' a standard in vitro time/kill-efficacy study technique.
  • Kowalski observes that if the concentrations of ozone in air at atmospheric conditions can be low enough to meet OSHA limits (i.e., 0.1 parts per million in room air) it can be used to deactivate pathogens in room air.
  • Kowalski further speculates that ozone can be used to sterilize surfaces of medical equipment.
  • ozone results in exposure that is very close to 100% including hidden areas, folds, and crevices of the skin and other objects. Exposing one's hands to ozone can substantially expose the fingernail crevice, which has positive implications due to the localized concentration of pathogens and contaminants.
  • United States patent 6,254,625 to Rosenthal et al. describes a hand sanitation apparatus based on ozone and UVC.
  • the apparatus described is the size of a small refrigerator and produces ozone from air by UVC radiation from germicidal lamps.
  • Rosenthal describes no process for preventing ozone from entering room air, which is critical to the safety of using such a device. What is needed in the art is an easy, quick, and effective hand sanitation technique that is not associated with common skin irritation and problems and does not result in unacceptable levels of ozone in the surrounding environment
  • a sanitizing apparatus comprising an enclosure, and inlet connector and an exhaust-outlet.
  • the enclosure is substantially impermeable to ozone and has an inner volume and a sealable opening.
  • the sealable opening can be open to receive an item being inserted into the enclosure or closed to form an airtight volume in the enclosure.
  • the inlet connector is attached to the enclosure and can be used to introduce ozone into the enclosure to sanitize the item placed therein.
  • the exhaust-outlet is also attached to the enclosure and can be used to release the gas from the enclosure once the sanitization process is complete.
  • a method of sanitizing using ozone is provided.
  • an item is inserted into an enclosure having an inlet-connecter, an exhaust-outlet, and a sealable opening.
  • the opening is sealed after insertion of the item to form a substantially air tight barrier around the item.
  • the inlet-connector is connected to an ozone source and used to fill the enclosure with ozone to sanitize the item.
  • the ozone is allowed to convert into a resulting oxygen gas mixture, and released from the enclosure through the exhaust-outlet.
  • Figure 1 illustrates one embodiment of the invention including a pouch that encloses a user's hands;
  • Figure 2 illustrates one embodiment of the invention in which a pouch is used in combination with an ozone hood having a vacuum pump to prevent ozone from escaping the hood enclosure;

  • Figure 4 illustrate one embodiment of the invention that can be worn as a cuff around a users arm.
  • the present invention comprises an enclosure into which an item can be inserted and sterilized.
  • an item to be sanitized is inserted into a sealable opening in the enclosure.
  • the enclosure is then sealed to completely enclose the item or surround the item, such that a portion of the item projects out of the enclosure.
  • the enclosure is then filled with ozone which sanitizes the portion of the item inserted therein.
  • the ozone breaks down into oxygen.
  • the sanitizer 100 includes an enclosure 110 that receives an item to be sanitized.
  • Figure 1 illustrates the sanitizer 100 being used to sanitize a user's hand 190. While the invention is discussed below with respect to the sanitization of a user's hand, it would be appreciated by one of skill in the art that other bodily extremities or inanimate items can be sanitized using the sanitizer 100.
  • the enclosure 110 illustrated in Figure 1 includes a sealable opening 160.
  • the opening 160 is preferably sized to accommodate a variety of objects. However, it can optionally be shaped and/or sized to accommodate a specific application.
  • the opening 160 can be circular and sized slightly larger than the average human forearm.
  • the opening 160 can be easily sealed around the forearm while the hand 190 is inserted in the enclosure 110.
  • the enclosure 110 is designed to be quickly removed or pulled on by a user.
  • the sealable opening 160 can include a fitting to create an airtight seal, such as a snap or elastic fitting.
  • the enclosure 110 further includes and inlet-connector 120 that is used to fill the enclosure 110 with ozone.
  • the inlet-connector 120 can be connected to an ozone source 130 whereby ozone can be introduced into the interior of the enclosure 110.
  • the inlet- connector 120 preferably includes a valve 180, such as a Schrader valve, to prevent any gas contained within the sealed enclosure 110 from leaking into the surrounding environment. Furthermore, the valve 180 can ensure the ozone is not unintentionally discharged from the ozone source 130.
  • the enclosure 110 can accommodate various shapes and materials as required by the intended application or generic design.
  • the enclosure 110 can be made from a flexible material (e.g., polyethylene) that can expand as ozone is released through the inlet connector 120 from the ozone source 130 into the enclosure 110.
  • a flexible material e.g., polyethylene
  • an enclosure 110 made of a flexible material permits a user's hand 190 a degree of tactile sensation through the enclosure 110 as well as the ability to manipulate objects outside the enclosure 110.
  • a further increased level of dexterity can be provided by shaping the enclosure 110 as a mitten or a glove into which a user's hand 190 can be inserted.
  • a glove-shaped, flexible enclosure 110 permits a user to manipulate the inlet- connector 120 and the ozone source 130 while the user's hands are inserted in the enclosure 110.

  • a flexible enclosure 110 provides a visual indication of the pressure and ozone contained therein by the swelling of the enclosure 110.
  • the enclosure 110 can include a pressure gage to measure the pressure in the enclosure 110.
  • the ozone source 130 can be provided through various solutions.
  • Figure 1 illustrates a pressurized cartridge based ozone source 130 solution.
  • Cartridges can be filled with ozone at a central location and distributed throughout the environment in which the sanitizer 100 will be used.
  • a user can have easy access to an ozone source 130 as necessary.
  • the cartridge can be portable and carried by a user from site to site.
  • Ozone made from relatively pure oxygen can deactivate pathogens faster than ozone made from air because the greater partial pressure of ozone in the gas.
  • the partial pressure of oxygen in air is 21%, which limits the potential ozone concentration.
  • a high concentration results if oxygen alone is used to make the ozone. For example, a 10% concentration, 100,000 ppm is highly effective.
  • a relatively high concentration and high partial pressure of ozone both contribute to enhancing the deactivation rate of the ozone. This can greatly decrease the time required to achieve hand sanitization or sterility.
  • Ozone has a limited lifetime as it breaks down into oxygen molecules. Ozone's half- life depends in part on its temperature and surroundings. The following table illustrates the half-life of ozone as a function of temperature, when there are no other influences.
  • ozone can be produced on demand, or near the time of use.
  • a plastic, airtight cartridge can be filled with oxygen, preferably medical grade, at elevated pressure.
  • the oxygen filled cartridge would have a very long storage lifetime, and can be converted to ozone on or near the day of use.
  • the conversion from oxygen to ozone can be accomplished by disposing a coaxial pin within the cartridge that can be excited with an RF voltage, thereby initiating a corona or Tesla discharge internal to the cartridge. The discharge converts the O 2 (oxygen) to O 3 (ozone). If the walls of the cartridge are relatively transparent one can observe the color change to the light blue that is characteristic of ozone.
  • the ozone can then be transferred to the enclosure 110 using the valve 180 of the inlet-connector 120 controlling the pressure.
  • the cartridge can be used multiple times since not all the ozone is transferred.
  • new ozone can be created on subsequent days by reapplying the RF voltage.
  • an ozone source can be placed in each room in which it is needed.
  • the ozone source can include a small, closed, discharge and storage volume (DSV) with a pressure gauge.
  • the DSV preferably contains an electrode that supports an RF corona type discharge.
  • Medical grade oxygen from an oxygen cartridge or a small oxygen storage tank is connected to the DSV to let oxygen into the DSV at a prescribed pressure greater than atmospheric. No ozone is transferred into the DSV, and no pump is needed.
  • the electrical discharge takes place in relatively pure oxygen and some of the oxygen within the volume is converted to ozone.
  • the pressure decreases as a result of the conversion to ozone and the measured internal pressure of the DSV indicates conversion.
  • the lifetime of the ozone in the box can be several hours at room temperature.
  • the pressure within the DSV after all oxygen has been converted to ozone is preferably above atmospheric to ensure that the enclosure 110 inflates with an ozone/oxygen mixture.
  • the inlet-connector can be disconnected from the ozone source.
  • the ozone then begins to convert to oxygen (two ozone molecules become three oxygen molecules) and the pressure in the enclosure 110 increases. The increased pressure indicates that the process of killing pathogens is complete.
  • the resulting gas mixture in the enclosure 110 is eliminated by activating an exhaust-outlet 140.
  • the exhaust-outlet 140 preferably includes a filter of charcoal, or other catalyst which completely converts the ozone to oxygen.
  • the exhaust- outlet 140 includes a sintered plug heated to high temperature which increases the rate of conversion from ozone to oxygen. Effectively, a minimal amount of ozone is released in the air.
  • the user's hand 190 is then removed from the enclosure 110. It can be desirable to sanitize both hands 190 of a user at the same time.
  • the sanitizer 100 is readily adapted to this task.
  • An optional inter-connect 150 that allows the passage of gases can be used to connect two enclosures 110 together.
  • a user can place one hand 190 in each enclosure 110 and the ozone released from the ozone source 130 will fill both enclosures 110.
  • the enclosures 110 can be glove- shaped and made from a flexible material, the user can still independently manipulate the inlet-connector 120, ozone source 130, and exhaust-outlet 140.
  • Ozone can reduce the surviving fraction of hand pathogens can to less than 10 "4 with an exposure of no more than a few seconds.
  • ozone does not cause cancer or any other serious damage to the skin. Minor irritations resulting from ozone exposure, similar to those associated with hand washing and alcohol rubs, can be treated Vitamin E based skin emollients. However, ozone does not crack or dry the skin, or cause allergic reactions and rashes.
  • the rate of a chemical reaction between a single pathogen and surrounding ozone molecules is proportional to the concentration of ozone molecules. While ozone exposure is clearly effective at sanitizing, it requires contact exposure to oxidize pathogens. A small fraction of pathogens clump together and tend to screen one another from the ozone so that the deactivation rate is lower. However, unclumped pathogens are quickly deactivated.
  • One way to reduce clumping is to rub the hands together, or rub the item being sanitized.
  • the friction created by rubbing causes surface pathogens to slough off and expose previously shielded pathogens or to break up clumps.
  • a further way to address clumping is the use of vibrations, and in particular ultrasonic energy, such as that used for ultrasonic cleaning.
  • the introduction of vibrational energey to reduce clumping increases the level of deactivation and reduces the necessary ozone exposure time.
  • the enclosure 110 can include a vibrational coupler 170 which allows introduction of vibrational (e.g., ultrasonic) energy at high intensity into the enclosure 110 containing the hands.
  • vibrational sources such as ultrasonic transducers can be included on the ozone source.
  • the enclosure 110 can be placed against the ozone source for both ozone filling and providing ultrasonic energy.
  • piezoelectric transducers at 40 KHz, about 1 cm in diameter, are commonly used in commercial ultrasonic cleaners. Such transducers would produce acoustic energy that is inaudible and at an intensity that is not damaging to the human ear.
  • the 40 KHz, ultrasonic radiation can be introduced into the pouch through a low loss, vibration coupler 170 in the enclosure 110 wall. Ultrasonic energy can thus be directed directly into the hand, for example by virtue placing a finger against the coupler
  • Human tissue being comprised of mostly water, readily transmits the acoustic energy and vibrates the skin surface thereby dec lumping pathogens on the skin as the ozone in the enclosure 110 sanitizes.
  • FIG. 1 illustrates an embodiment of the invention that includes a gas exhaust system.
  • the user's hand 290 is inserted through a sealable opening 260 into an enclosure 210, such as a glove or pouch having an inlet-connector 220.
  • the enclosure 210 is then inserted into a second enclosure 280 through an opening 265.
  • the second enclosure 210 can be integrated with the ozone source 230 and vibrational energy source 270.
  • An exhaust apparatus 235 such as a small vacuum pump or fan, can be included in the second enclosure 280.
  • the exhaust apparatus moves air into the opening 265 and out an exhaust outlet 240.
  • any ozone that escapes the enclosure 210 is moved away from the user and vented through exhaust outlet 240, which is preferably located opposite the user.
  • the exhaust outlet 240 can include a filter 245 that increases the conversion of ozone to oxygen. Filters for the exhaust sintered from a variety of materials, for example stainless steel or activated carbon particles, provide good catalysts for converting ozone to oxygen. This conversion can be further enhanced by heating the filter, for example to a temperature greater than 250 degrees C.
  • the second enclosure 280 can also include a heat source 250 along the interior of the enclosure to further convert any ozone that leaks from the first enclosure 210 to oxygen.
  • the heat source can 250 include incandescent light bulbs or other heating elements known in the art.
  • the exhaust apparatus of the sanitizing device 200 makes the system substantially ozone leak-proof.
  • the enclosure 210 preferably remains within the second enclosure 280 during the treatment period for protection against a leak and for the ultrasonic input provided by the vibrational coupler 270 for declumping. This configuration allows for higher concentrations of ozone to be provided by the ozone source 230 because the danger of a potential leak is virtually eliminated

  • the enclosure 310 can be a rigid or flexible structure.
  • the user inserts a hand
  • the opening 360 can be shaped to provide an opening smaller than a user's forearm or wrist. Thus, the user must stretch the opening to insert the hand 390 and the opening will be flush and tight around the user's extremity thereby preventing leaks.
  • the opening 360 ring can then be inflated to form an air tight seal with the user's extremity.
  • the ring can be deflated so that the user's hand can be removed from the enclosure 310 through the opening 360 without rubbing against the side of the opening 360. Thus the risk of cross contamination is reduced.
