Definitions

  • Sterilization may be considered the killing of all DNA-based organisms present on the object before the introduction of the object into a sterilizer.
  • DNA-based organisms may include, but are not limited to, those organisms that cause: Anthrax; Severe Acute Respiratory Syndrome (SARS); and Avian influenza (also known as "Bird Flu”).
  • SARS Severe Acute Respiratory Syndrome
  • Avian influenza also known as "Bird Flu”
  • Many methods are known for sterilizing liquid, such as water, to make the liquid safe to drink, i.e., to remove harmful microorganisms. For instance, the liquid may be heated to a rolling boil for a set period of time, the liquid may be filtered by a filter having a predetermined absolute pore size and/or the liquid may be chemically treated by chlorination or iodination.
  • FIG. 7 is a sectional view of a funnel filter of the second exemplary portable UV sterilizer of FIG. 4.
  • the releasable attachment between the body 12 and the electronics housing 24 is facilitated by a bottom bulkhead 16, which has an aperture corresponding to the bottom aperture in the body 12.
  • the attachment of the body 12 to the bottom bulkhead 16 is accomplished by way of a bottom spigot 32 formed as an externally threaded hollow cylinder with a flange at one end.
  • the cylinder of the bottom spigot 32 passes through the bottom aperture of the body 12 with the flange remaining in the interior of the body 12.
  • the cylinder also passes through the aperture in the bottom bulkhead 16.
  • a liquid, or an object, to be sterilized may be placed into the sterilization chamber through the aperture in the main body threaded ring 14 with the stopper 38 removed.
  • the stopper 38 may then be press-fit into the aperture in the main body threaded ring 14 so that the sterilization chamber is enclosed during sterilization.
  • the activation switch 54 the bulb 26 is switched on and the liquid, or the object, is bathed in UVC radiation, thereby killing DNA-based organisms present in the liquid, or on the object.
  • Feedback to the user may be provided by the LEDs 48, for example to- indicate to the user that the bulb 26 has been powered on and to indicate that the bulb 26 is healthy.
  • the source of electrical power for the bulb 26 may be one of multiple sources.
  • the bulb 26 may, for example, receive power from batteries in the battery pack 56.
  • the bulb 26 may receive power from an AC adapter via the AC adapter input receptacle 52.
  • the AC adapter input receptacle 52 may be used to supply power necessary to recharge the batteries.
  • the person of ordinary skill in the art should recognize that the bulb 26 may be powered by direct AC power, power from solar panels, power from a hand- or foot-cranked generator and power from a wind generator among other power sources.
  • the measured value may be compared to a lower threshold computed by subtracting a small delta value from the nominal value. If the measured value is lower than the lower threshold, an alarm may be raised. Additionally, the measured value may be compared to an upper threshold computed by adding another (or the same) small delta value to the nominal value. If the measured value is higher than the upper threshold, an alarm may be raised. This will facilitate ensuring operation within a predefined range.
  • a quartz sleeve 140 is inserted into the sterilization chamber through the cylinder portion of the bottom spigot 132 and held in place in the bottom spigot 132.
  • the bottom of the quartz sleeve 140 may be surrounded with one or more silicone o-rings 76 to assist the formation of a seal between the quartz sleeve 140 and the bottom spigot 132.
  • the control board 120 includes an activation switch 154 to which access is allowed through an aperture 154A in the bottom bulkhead 116. Furthermore, the control board 120 may have one or more light emitting diodes (LEDs) 148. The LEDs 148 may pass through corresponding apertures 148A in the bottom bulkhead 116 so that the state of the LEDs 148 may be viewed by a user.
  • LEDs light emitting diodes
  • the cup 128 and funnel 64 may be removed from respective attachment to the body 112 and the stopper 138 may then be removed from the aperture defined in the top of the body 112.
  • the funnel 64 may be inverted and placed over the aperture in the top of the body 112.
  • a liquid may then be introduced to the funnel 64 such that the liquid may flow through the filter 70 and into the body 112.
  • the stopper 138 may then be re-threaded into the aperture.
  • the filter 70 can be either be gravity fed, or power assisted. Power assistance can correspond to a manual pump or an AC or DC actuated pump (not shown).

Abstract

La présente invention concerne un dispositif de stérilisation aux ultraviolets (UV) portable comprenant un corps dans lequel peuvent être introduits du liquide ou de petits objets. Une ampoule disposée à l'intérieur du corps, peut être activée de sorte que le rayonnement issu de l'ampoule, détruit les organismes à base d'ADN présents dans le liquide ou sur les objets, pour ainsi stériliser le liquide ou les objets. L'utilisation d'un revêtement hautement réfléchissant sur l'intérieur du corps, permet l'utilisation d'une ampoule à UV de voltage inférieur à celui qui serait normalement nécessaire.
