Definitions

  • Direct contact causes the contagium to be transmitted from the carrier to another, who may become infected and/or pass the contagium on to yet another. Nosocomial infections are particularly prevalent with medical personnel, who may come into contact, knowingly or not, with infectious diseases.
  • Indirect contact occurs when the carrier touches some article, thereby depositing the contagium and permitting it to be contacted by another coming into contact with the article. Many contagia are spread by contact, directly or indirectly with the hands.
  • wash stations which are utilized for the washing of hands.
  • the wash station has a valve, possibly foot or leg operated, for controlling water flow from a faucet to a sink.
  • a source of cleansing agent such as a liquid soap
  • Hot air dryers are normally not provided in a hospital environment, because the flow of air has a tendency to spread the contagia. Wash stations suffer from numerous drawbacks, such as improper quantity of soap, a need to touch a valve or other potentially contaminated site, and the excessive use of water while the washing operation takes place.
  • the disclosed invention refers to a wash station, suitable for both hospital and food-handling establishments according to the preamble of claim 1.
  • the wash station has infrared sensors for detecting the presence of a user, and a desire for that user to initiate a hand washing operation. Once a potential user is detected, then a control system causes a sufficient quantity of water to be dispensed in order to permit the hands to be wet. A predetermined amount of soap sufficient to cleanse the hands is then dispensed, and a further quantity of water is dispensed in order to permit the hands to be rinsed. Finally, a selected length of roll toweling is dispensed.
  • Such a wash station is known from US-A-5,031,258 .
  • US-A-5 199 118 further discloses a wash station, which has a push button for causing water to be dispensed from the water faucet for so long, as the push button is actuated.
  • the wash station has a soap dispensing nozzle, which is located on an inclined section of a face panel above the basin.
  • JP 04216726 discloses a washing station, wherein liquid soap is discharged from a tank to a nozzle, when hands are detected by a sensor, which is provided underneath the nozzle. When the hands are pulled back, the discharging of the liquid soap is stopped. After that, when the hands are extended to the lower side of a water discharging port, then they are detected by a sensor and feed water is discharged from the water discharging port.
  • the wash station according to the present invention differs by the provision of the features of the characterising portion of claim 1.
  • Wash station W has a cabinet 10 and a vertical support 12.
  • the cabinet 10 and support 12 may, as shown, be separate structural elements, or they may be integral or the support 12 might be part of a wall or the like.
  • cabinet 10 and vertical support 12 be manufactured from stainless steel, those skilled in the art will understand that other compositions might be appropriate, such as when wash station W is in a restaurant environment.
  • Sink 14 is mounted to top 16 of cabinet 10. Also mounted to top 16 is an infrared sensor 18, a water spout 20, and a selector switch. Cabinet 10 may have handles 24 and 26, permitting doors 28 and 30 to be opened.
  • An electrically operated roll towel dispenser 32 is mounted to vertical support 12.
  • Dispensing means has an infrared sensor 34, which may be a passive infrared detector, as compared with the active infrared detector of the sensor 18.
  • an infrared sensor 34 which may be a passive infrared detector, as compared with the active infrared detector of the sensor 18.
  • a length of toweling 36 extending from dispenser 32, as well as display 38 which indicates the number of uses of wash station W. While we prefer the use of paper towels, it is merely necessary that a continuous length of tearable drying material be dispensed from dispenser 32. Sheet towels should not be used, because they run the risk of contact with the possibly contaminated dispenser.
  • a soap spout 312 is adjacent water dispensing spout 20, and is secured to top 16.
  • Spout 312 has a nozzle 314 which lies above sink 14, and through which soap, bactericide, or a suitable anti-microbial agent is dispensed.
  • the soap supplied to nozzle 314 is supplied from any suitable pump.
  • the pump is a peristaltic pump.
  • spout 312 Incorporated into spout 312 is an active infrared sensor system for actuating the pump in order to cause soap to be dispensed. Lenses 316 and 318 are provided for transmitting the infrared signal, and for receiving the reflected signal, respectively. Soap will not be dispensed until the user has triggered the sensor system of spout 312 by placing his or her hand in operative relationship for indicating by reflection of the light that soap is desired. Thus, a user placing his or her hands under water spout 20 will cause water to be dispensed for so long as those hands are so positioned, and the wash station W will not be placed into the "hand washing" mode until the sensor of spout 312 is actuated.
  • Push button 320 is therefore provided, optionally at towel dispenser 32, for this purpose.
  • the push button 320 may be a suitable button which stays locked until pushed again, or time controlled or otherwise, so that water will flow to water spout 20 for so long as the push button 320 is actuated.
  • an alphanumeric display 322 is provided in order to provide information for the user, such as instructions for use.
  • the display 322 may be incorporated into the towel dispenser 32, or may be otherwise located.
  • the alphanumeric display thus is readily observed by the user, and may not only provide instructional information but other information, such as time elapsed, time to next step, etc., which will help to keep the user at the wash station W for the duration of the hand wash cycle.
  • the display 322 may also be used to provide information to the hospital, for example, on total number of uses, total number of proper uses, and other information permitting the hospital to determine that the wash station W is being properly used and how frequently used.
  • FIG. 2 illustrates the control system of the wash station W.
  • a controller which may be a microprocessor or programmable controller, has inputs from the water sensor 18, the soap sensor 316, 318, and the towel dispenser sensor 34.
  • Towel dispenser sensor 34 in this embodiment, preferably is an active infrared sensor.
  • the outputs from the controller are to the valve, such as either or both valves, the pump, such as peristaltic pump, and towel dispenser 32.
  • controller will cause the valve to the water spout 20 to be operated, with the result that water will flow thereto. Water will continue to be dispensed for so long as the sensor 18 detects a user. Alternatively, water will continue to be dispensed for so long as push button 320 is operated.
  • the control of water and soap is based upon a preprogrammed sequence generally known for example from US-A-5,031,258 . Specifically a pump is actuated to dispense soap through nozzle 314, while the flow of water to water spout 20 is stopped. Once the hands have had sufficient time to be lathered, then water is again dispensed through water spout 20. Once sufficient water is dispensed, then the water valve closes, and towel 36 is dispensed from dispenser 32 by virtue of its electric motor.
  • the alphanumeric display 322 which may be a CRT screen, liquid crystal display, or the like, is also actuated by the controller to provide information to the user.
  • display 322 may initially be set to display to the user that wash station W is in the water only mode. Once soap is dispensed by the controller being switched to the hand washing mode, then the display may inform the user the step then underway, how much time remains until initiation of the next step, and similar information.
  • alphanumeric display 322 may also provide other sorts of information having the intent of keeping the user at the wash station W for the duration of the hand washing cycle.
  • An individual may e reluctant to appear to be taking instructions from wash station W or may become impatient during the hand washing sequence.
  • display 322 may provide information such as hand washing frequency, general purpose information such as about the importance of hand washing, or even more general information about current events. The purpose is to keep the user at the wash station W so that the hand washing sequence will be satisfactorily completed.
