Definitions

  • the present invention relates to hand sanitization methods and apparatus and to electrostatic spraying of fluids. Even more particularly, the present invention relates to a hand sanitization method and apparatus wherein both hands are sprayed simultaneously without a static charge buildup on the body.
  • Some hand sanitizing stations require manual actuation to dispense the germicidal product. Manual contact can lead to contamination of the very implement meant to combat the problem. Foaming and gelling of the germicidal product provides a means to bulk up the product so manual distribution of the germicidal product about the hands is more likely. Unfortunately, quantities of the germicidal product beyond that required to provide sanitization are needed just to enable distribution of the product about the hands. The excess product is messy to use and requires extended evaporation time on the hands. Further, excess product may lead to other dermatological problems such as drying and cracking of the skin or even destruction of the natural micro biological flora of the hands.
  • European patent application publication number 056767841 to Mongkol on April 29, 1992 discloses a fluid dispensing device for disinfecting of the hands which uses a infrared detector to activate a pressurized spray bottle when the user's hand is placed beneath a spray valve.
  • the intent is to "spray fluids and readily irrigate in a fully automated manner the entire surfaces of the hands".
  • the simple spray from a spray bottle has no affinity for the hands and thus still requires the user to move the hands beneath the spray to achieve overall coating.
  • much of the active germicidal fluid is wasted as overspray, familiar to anyone who has used a paint ray can. Further still, the overspray of the germicidal fluid contaminates the air about the device and poses an inhalation problem.
  • U.S. Patent 5,292,067 issued to Jeffries et al. on March 8, 1994 discloses an apparatus for electrostatic spraying.
  • the apparatus disclosed by Jeffries et al. is a hand held device particularly concerned with the spraying of relatively low resistivity liquids such as aqueous and alcohol based liquids used in personal care products such as deodorants, anti-perspirants, scents and hair sprays.
  • a handgrip portion or trigger provided with a contact exposed for engagement with the hand so as to provide a path to ground in use. Since the emitted electrostatic spray carries a charge to the target skin surface, a build up of charge on the user results. Without the path to ground, the electrostatic charge of the user will accumulate usually resulting in an unpleasant static discharge.
  • An object of the present invention is to provide an improved hand sanitizing apparatus which provides a consistent effective hand sanitization by dispensing an even coating of germicidal fluid to the hands of the user substantially independent of the hand manipulation of the user.
  • Another object of the present invention is to provide a hand sanitizing apparatus which provides the minimal quantity of product required to provide effective germicidal activity on transient pathogens while minimizing the destruction to the natural flora and condition of the hands.
  • a further object of the present invention is to encourage compliance by providing a hand sanitizing apparatus that is simple, convenient, and fast to use with virtually no residue or inhalation effect.
  • Additional objects of the present invention are: to provide a hand sanitizing apparatus that sanitizes both hands simultaneously, to provide a hand sanitizing apparatus that monitors proper hand placement and treatment; and to provide a hand sanitizing apparatus that indicates visually and/or audibly the aspects of operational status, user treatment, and compliance.
  • a dispensing cycle actuator operated by the user to initiate distribution of electrostatic energy from the power source to the electrostatic fluid emitters so that the germicidal fluid from the fluid supply is directed to the electrostatic fluid emitters and flows therefrom toward the user's hands when the user's hands are placed in proximity to the electrostatic fluid emitters.
  • the frame may further comprise a first cell to apply the germicidal fluid to a right hand of the user and a second cell to simultaneously apply the germicidal fluid to a left hand of the user.
  • Each of the first and second cells may have at least one electrostatic emitter directed at a user's hand. Where there is a first electrostatic emitter for the right hand and a second electrostatic emitter for the left hand, the first electrostatic emitter may have an electrostatic polarity opposite from the second electrostatic emitter during the dispensing cycle.
  • first and a second right hand electrostatic fluid emitter attached to the frame and located to apply the germicidal fluid to a right hand and a first and a second left hand electrostatic fluid emitter attached to the frame and located to apply the germicidal fluid to a left hand, wherein the first right hand and first left hand electrostatic fluid emitters have an opposite electrostatic polarity from the second right hand and second left hand electrostatic fluid emitters during the dispensing cycle.
  • the apparatus may further comprise a means to dispense a predetermined quantity of the germicidal fluid onto the user's hands, such as a metering pump or a metering valve intermediate the supply of germicidal fluid and the electrostatic fluid emitter. Additionally the apparatus may further include a means for indicating the operating status of the apparatus.
  • the supply of germicidal fluid may even be a replaceable cartridge.
  • a method of uniformly coating a user's hands with a germicidal fluid without the need for post-coating hand manipulation, comprises the steps of placing each of a user's hands into a hand sanitizing apparatus and initiating electrostatic spraying of each of the user's hands simultaneously with the germicidal fluid while each of the user's hands serves as a target for receiving electrostatically charged droplets of spray.
  • the hand sanitizing apparatus has at least two electrostatic fluid emitters.
  • Steps also include discontinuing the electrostatic spraying when sufficient germicidal fluid has been sprayed to uniformly coat each of the user's hands, such that substantially no excess fluid drips from each of the user's hands and substantially no overspray results, and removing each of the user's hands from the hand sanitizing apparatus.
  • the user's arms and body may provide a conductive electrical path for charges of opposite polarity between the user's hands to insure substantially no charge is built upon the user while sanitizing the user's hands.
  • each of the user's hands may provide a conductive electrical path for charges of opposite polarity on each of the user's hands to insure substantially no charge is built upon the user while sanitizing the user's hands.
  • the electrostatic spray may be pulsed from each of the electrostatic fluid emitters, such that alternate pulses have opposite polarity, thereby insuring that substantially no charge is built upon the user while sanitizing the user's hands.
  • the user may be grounded in order to insure substantially no charge is built upon the user while sanitizing the user's hands.
  • a predetermined quantity of the germicidal fluid may be dispensed onto the user's hands.
  • FIG. 1 is a perspective view of a preferred embodiment of hand sanitizer of the present invention.
  • FIG. 2 is an electric and hydraulic schematic of a preferred embodiment of the present invention.
  • Hand sanitizer 10 comprises a frame 11 further comprising a right hand cell 12 and a left hand cell 13. Electrostatic spray nozzles 61, 62 and 63 are visible in right hand cell 12 while electrostatic spray nozzles 71, 72, and 73 are visible in left hand cell 13.
  • a display panel 22 provides operational status information of the hand sanitizer and instructions to the user.
  • An audio transducer 23 provides audible signals to compliment the visual display panel 22.
  • the term "cell" means a position where one hand is sprayed with fluid separately from the other hand.
  • One cell for one hand is intended to be isolated from a corresponding cell for the other hand of a user so that the fluid sprays do not mix.
  • cells may or may not have partitions for separation purposes if sprays are aimed such that hands may be sprayed separately without significant fluid mixing.
  • FIG. 2 there is shown an electric and hydraulic schematic of a particularly preferred embodiment of the hand sanitizer 10.
  • a plug-in transformer 20 reduces line voltage to an operating low voltage, preferably about 12 volts.
  • Transformer 20 provides power to a controller 21.
  • Controller 21 provides operational status and instruction signals to display panel 22.
  • Controller 21 also provides appropriate signals to audio transducer 23.
  • Controller 21 further provides power to right hand and left hand presence detection systems comprising infrared emitters 30 and 31 and infrared sensors 32 and 33.
  • sensors 32 and 33 recognize a break in the signal from emitters 30 and 31, respectively.
  • the infrared emitter and sensor system permits non-contact detection of the hand for the sanitization cycle.
  • sensors 32 and 33 comprise arrays which detect hand insertion and proper location.
  • the sensor arrays may further detect splaying of the fingers by, for example, by "seeing" multiple shadows which indicate the finger are spread apart. For most effective hand sanitization, the fingers are preferably spread apart to enable the antimicrobial liquid to coat all the hand surfaces, even between the fingers.
  • controller 21 may first indicate via display panel 22 and audio transducer that a cycle has been initiated. Alternatively, a body contact sensor could be used to initiate a dispensing cycle. However, it is most preferable that the user's hands not contact any surface while being sprayed. Concurrently with the activation of audio and visual indicators, power is distributed to high voltage generator 25 which provides high voltage of opposite polarity to electrostatic couplings 26 and 27. In FIG. 2, a negative voltage is applied to the right hand liquid germicidal product 50 and a positive voltage is applied to left hand liquid germicidal product 51. When appropriate voltage has been attained, preferably about 5000 volts to 15,000 volts, controller 21 provides power to pump motor 24 which in turn actuates pumps 52 and 53.
  • pumps 52 and 53 draw germicidal product 50 and 51 from electrical isolation reservoirs 54 and 55, respectively, and simultaneously propel germicidal product 50 and 51 through right hand electrostatic emitters 71, 72, and 73 and through left hand electrostatic emitters 81, 82, and 83, respectively.
  • the electrostatic emitters are similar in operation to nozzles disclosed in U.S. Patent No. 5,292,067 to Jeffries et al., such as the nozzles shown in Figure 1 and Figure 4, wherein atomization is predominantly a result of the applied high voltage electric field induced ligamentary spraying of the liquid followed by breakup of the ligament into droplets.
  • sensors 32 and/or 33 will indicate to controller 21 of such condition and interrupt the dispensing cycle.
  • hand sanitizer 10 will indicate to the users a premature hand removal condition either by visual or audible means and instruct the user to repeat the sanitization cycle by properly inserting the hands.
  • Germicidal product 50 and 51 are semi-conductive and thus may transport high voltage back to isolation reservoirs 54 and 55, respectively.
  • isolation reservoirs 54 and 55 are fed from a larger common bulk reservoir 60.
  • germicidal products 50 and 51 are electrostatically charged to opposite polarities, germicidal products 50 and 51 must be electrically isolated from one another. It is further preferred to electrically isolate bulk germicidal supply 61 from germicidal products 50 and 51 during a dispensing cycle. In the embodiment of FIG. 2, there is shown air gaps 62 and 63 above germicidal products 50 and 51 respectively to provide such high voltage electrical isolation. Since electrostatic charging of germicidal product 50 and 51 is an intermittent operation occurring during the dispensing cycle, electrical isolation during quiescent periods between dispensing is not required. Hence, germicidal product may flow through solenoid operated valves 64 and 65 during quiescent periods.
  • Germicidal product flow of bulk germicidal product 61 through solenoid operated valves 64 and 65 onto the surfaces of germicidal products 50 and 51 in isolation reservoirs 54 and 55, respectively, during a dispensing cycle could result in an electrical path for high voltage transmission to bulk germicidal product 61 or between germicidal products 50 and 51.
  • Low level sensors 56 and 57 detect low level in isolation reservoirs 54 and 55 in order that controller 21 can activate solenoid operated valves 64 and 65 between dispensing cycles.
  • High level sensors 58 and 59 detect high levels of germicidal products 50 and 51, respectively, to indicate to controller 21 to deactivate solenoid operated valves 64 and 65, respectively. Other means for providing high voltage isolation may be used.
  • a high voltage peristaltic isolation pump wherein rollers pinch off a resilient tube in multiple locations about a cylindrical chamber may be employed to provide electrical isolation and may further serve as a pumping means.
  • Sensor 70 detects low germicidal fluid level of bulk reservoir 60 and may be used by controller 21 to provide an appropriate indication to the users.
  • bulk reservoir 60 is a replaceable cartridge prefilled with a quantity of germicidal product.
  • a typical dispensing cycle may apply about 0.3 ml to about 0.5 ml of germicidal product.
  • a bulk reservoir 60 having a capacity of about one liter and which may be housed within the frame of the hand sanitizer could provide 2000 dispensing cycles. Larger bulk supplies may be remote from the actual hand sanitizer and possibly connected by means of a small tube.
  • the predetermined quantity dispensed would depend upon several factors, e.g., the particular germicidal ingredients, size of user's hands and the degree of germ kill required.
  • a particular advantage of the hand sanitizer of the present invention is the ability to apply a light even coating of the germicidal product to the hand surfaces because of the electrostatic attraction of the germicidal product to the user's hands.
  • the light coating minimizes the adverse affects of the germicidal products such as dehydration of the skin, and destruction of the natural flora of the hands.
  • bulk reservoir 60 may be removed from snap seal 69 upon emptying of bulk germicidal product 61.
  • probe 68 Upon removal of bulk reservoir 60, probe 68 will be withdrawn from the interior of bulk reservoir 60 permitting check ball 66 to seat onto seal surface 67 thus trapping any residual germicidal product 61.
  • probe 68 Upon installation of a subsequent bulk reservoir 60 in, for example, the form of a prefilled cartridge, probe 68 will dislodge check ball 66 from seal surface 67 thus permitting flow of bulk germicidal product 61 to solenoid operated valves 64 and 65.
  • Other means may be employed to open a new prefilled product cartridge upon installation such as pierced membranes and deformable resilient valves.
  • a first electrostatic emitter in a right hand cell is charged to high voltage positive electrostatic polarity while a second electrostatic emitter in the right hand cell is charged to a high voltage negative electrostatic polarity during a dispensing cycle.
  • a similar configuration would be presented in a left hand cell, i.e., opposite electrostatic polarities between electrostatic emitters in the left hand cell.
  • the opposite charges carried by the emitted electrostatic sprays from the oppositely charged electrostatic emitters within each cell tend to cancel upon contact with the hands through natural conductive paths within the hand.
  • the effect is generally similar to the neutralization of opposite charges between the right and left hands in hand sanitizers having opposite charges between right and left hand cells.
  • an advantage of the opposite electrostatic charged sprays within each cell is that an individual hand may be treated without the buildup of electrostatic within the user.
  • the electrostatic emitters are pulsed on and off. Each pulse has an opposite charge. This is another way to prevent a charge buildup on a non-grounded user and to thereby maintain the user's hands as neutrally charged targets during electrostatic spraying.

Abstract

Appareil de désinfection (10) pour les mains qui utilise au moins deux émetteurs électrostatiques (71-73, 81-83) pour distribuer un liquide germicide sur sensiblement toute la surface des mains d'un utilisateur quand celui-ci met ses deux mains à proximité des émetteurs (71-73, 81-83). L'appareil (10) comprend un cadre (11) sur lequel sont fixés les émetteurs électrostatiques (71-73, 81-83), disposés de préférence dans deux cellules (12, 13) qui séparent le jet dirigé sur une main du jet dirigé sur l'autre main, un réservoir (60) de fluide germicide (50, 51) en communication fluidique avec les émetteurs (71-73, 81-83), une alimentation (20) conçue pour amener une énergie électrostatique aux émetteurs (71-73, 81-83), et un actionneur de cycle de distribution (21) mis en marche par l'utilisateur, qui distribue l'énergie électrostatique venant de l'alimentation (20) aux émetteurs (71-73, 81-83), de façon qu'une quantité prédéterminée de fluide germicide (50, 51) soit dirigée depuis chaque émetteur (71-73, 81-83) vers chaque main de l'utilisateur durant le cycle de distribution. Dans un premier mode de réalisation, chaque main est aspergée par une charge opposée. Dans un deuxième mode de réalisation, chaque main est aspergée par de multiples émetteurs électrostatiques (71-73, 81-83) ayant des charges opposées. Dans un troisième mode de réalisation, l'émetteur électrostatique (71-73, 81-83) dirigé vers chaque main est pulsé, de façon que chaque impulsion ait une charge opposée. Dans un quatrième mode de réalisation, l'utilisateur est mis à la terre, ce qui rend inutile l'utilisation de charges opposées.
