Definitions

  • Hand care in the workplace implicates both work related activities and worker health.
  • Hand hygiene is essential for certain activities and services including, particularly, healthcare, food preparation, and food service.
  • Hand hygiene is important for virtually all workplaces to maintain a healthy environment and to limit spread of bacteria, viruses and other disease causing microorganisms.
  • Hand hygiene can be accomplished by washing with soap and water and by using liquids such as a sanitizing product which does not require water or rinsing of the product.
  • Hygiene products that are used for hand hygiene are commonly dispensed by dispensers that are located where hand hygiene is desired.
  • Hand skin care products can promote worker health in avoiding and treating hand skin conditions that can reduce worker performance and productivity.
  • HAIs healthcare acquired infections
  • MRSA methicillin-resistant staphylococcus aureus
  • VRSA vancomycinresistant staphylococcus aureus
  • the World Health Organization has identified five moments of hand hygiene in a healthcare setting. Those five moments for hand hygiene actions are: 1) before patient contact; 2) before performing an aseptic task; 3) after body fluid exposure risk; 4) after patient contact, and 5) after contact with patient surroundings. These five moments provide guidelines for hand hygiene within a healthcare setting. Compliance with such guidelines may be evaluated based on monitoring the number of hand hygiene events at locations within a healthcare institution at each of the five moments.
  • Compliance with guidelines or recommended practices for hand hygiene may be monitored using one of a number of approaches including direct observation, tracking product consumption, and more recently electronic monitoring systems.
  • a compliance rate can be ascertained for a predetermined area of interest over a predetermined time period.
  • Some low cost monitoring systems rely on the dispensers being in fixed locations, so that the dispenser usage events that are captured are assigned to the correct area of interest.
  • dispenser monitoring systems are not capable of monitoring dispensers fixed to portable equipment since the system cannot determine where the equipment was when the usage event was captured.
  • RTLS real-time locating system
  • this approach does not qualify as ‘low-cost’ solution as it requires the installation of an extensive RF infrastructure that breaks down the facility into zones in order to correctly triangulate the position of any given dispenser. Triangulation systems are also subject to a substantial amount of position error absent line of sight conditions.
  • the present inventors have recognized a need for a point-of-care dispenser that: 1) can be securely installed in a wide variety of locations; 2) is securely lockable to fully prevent the theft of the hand hygiene product; and/or 3) can be integrated into a low cost hand hygiene compliance monitoring system whereby dispenser usage events are captured and assigned to a relevant predetermined area of interest.
  • a point-of-care hygiene dispenser and an electronic hand hygiene event monitoring system are disclosed.
  • One embodiment is directed to a point-of-care dispenser and a corresponding electronic monitoring system, wherein the point-of-care dispenser is movable between predetermined zones of interest. Actuation of the point-of-care dispenser results in an RF transmission event at a first power level having a transmission range generally limited to a predetermined zone of interest in which the point-of-care dispenser has been actuated.
  • the embodiment also includes a plurality of RF transceivers disposed in each of the predetermined zones of interest.
  • Each RF transceiver is configured to receive the RF transmission events from a point-of-care dispenser in the respective predetermined zone of interest, and to transmit a further RF signal corresponding to the actuation at a second power level having a transmission range extending beyond the pre-determined zone of interest.
  • the point-of-care dispenser comprises a main body having an interior defining a hand hygiene cartridge chamber, and a dispenser cover secured with the main body for pivotal movement of the dispenser cover between an open condition with respect to the main body, and a closed condition with respect to the main body.
  • the point-of-care dispenser also includes at least one main body interlock secured to the main body, wherein the at least one body interlock includes an undercut feature, and at least one dispenser cover interlock secured to the dispenser cover, wherein the at least one dispenser cover includes an undercut feature.
  • the undercut features of the at least one dispenser cover interlock and the at least one main body interlock engage one another when the dispenser cover is in a closed position with respect to the main body. Engagement between the undercut features increases in response to an increase in a prying force used to move the dispenser cover from the closed condition to the open condition.
  • a still further embodiment is directed to point-of-care dispensing system comprising a point-of-care dispenser having a dispenser cover and a main body, a locking mechanism configured to secure the dispenser covers with the main body in a closed condition, and a docking unit configured for mounting with the point-of-care dispenser.
  • the docking unit and point-of-care dispenser are interconnected with a further locking mechanism that is only accessible for release of the point-of-care dispenser from the docking unit when the dispenser cover and main body are in an open state.
  • FIGS. 1 through 4 illustrate a point-of-care dispenser that may be used in an electronic monitoring system.
  • FIG. 5 is a diagram of an electronic monitoring system that may be used to monitor one or more point-of-care dispensers, for example, such as those shown in FIGS. 1 through 4 .
  • FIGS. 6-12 show examples of various elements of a point-of-care dispenser that includes security features that address issues such as theft of the hand hygiene cartridge.
  • FIGS. 13-17 show a point-of-care dispenser system in which a point-of-care dispenser is configured for secure mounting with a corresponding docking unit.
  • FIGS. 18-21 show a range of individual clamping options in which, through the use of mechanical fixings and/or tamper resistant mechanical fixings, the point-of-care dispenser can be securely mounted onto a range of healthcare equipment.
  • FIGS. 1 through 4 illustrate a point-of-care dispenser 10 having a main body 15 and dispenser cover 20 .
  • the main body 15 and dispenser cover 20 are dimensioned to enclose a hand hygiene cartridge 25 , or other container for a hand hygiene product.
  • the hand hygiene product is dispensed from the hand hygiene cartridge 25 by actuating a dispensing pump 30 at a top of the care dispenser in the direction shown by arrow 35 .
  • the ultra-low power transmission elements are disposed at a rear portion of the main body 15 to provide an ultra-low power RF signal indicating that the dispensing pump 30 has been actuated.
  • the ultra-low power transmission elements shown generally at 40 , are disposed at a rear portion of the main body 15 .
  • the ultra-low power transmission elements 40 include an ultra-low power radio unit 45 , a trigger magnet 50 , and a reed switch 55 .
  • the dispensing pump 30 In operation, as the dispensing pump 30 is depressed, its travel is tracked by a follower 60 .
  • the trigger magnet 50 is configured to move with the follower 60 as the dispensing pump 30 is pressed and released. In turn, the motion of the trigger magnet 50 actuates the reed switch 55 , which activates the ultra-low power radio unit 45 . As the magnetic field of the trigger magnet 50 acts upon the reed switch 55 , the ultra-low power radio unit 45 is energized and transmits a dispenser usage event via an ultra-low power RF signal transmission. Multiple pushes that occur within a predetermined time, such as 2.5 seconds, may be collated to represent a single usage event with multiple activations.
  • the trigger magnet 50 is positioned so that it only reports hand hygiene events in which the pump is activated sufficiently to dispense an appropriate volume of hand hygiene product. As the pump returns to the top of a stroke, so does the follower 60 propelled by a return spring, ensuring that the magnets of the trigger magnet 50 do not generate a magnetic field that acts upon the reed switch 55 .
  • FIG. 5 shows an electronic hand hygiene event monitoring system 200 that may accomplish such tracking.
  • the point-of-care dispenser 10 is portable between predetermined zones of interest A, B, and C, as shown by arrows 205 .
  • Actuation of the point-of-care dispenser 10 results in an RF transmission event at a first power level having a range generally limited to the greatest distance between the point-of-care dispenser 10 and a corresponding higher power transceiver disposed respectively in each the predetermined zones of interest A, B, or C.
  • the range may be selected so that the RF transmission events from a point-of-care dispenser 10 in a first one of the predetermined zones of interest are not received by the transceiver in a second one of the predetermined zones of interest.
  • the RF transmission events will have different amplitudes, and a corresponding transceiver may differentiate between RF transmission events occurring in different predetermined zones of interest using signal amplitude by, for example, only accepting/responding to RF transmission events occurring above a predetermined signal amplitude.
  • the transceivers in each of the predetermined zones of interest may be configured to respond to different predetermined signal amplitudes to accommodate different zone sizes.
  • the portable point of care dispenser 10 may be configured to transmit an identification with the dispenser usage event that identifies the source of the event to be a portable dispenser. With this addition, dispenser usage events may be identified upon receipt of the event.
  • the first power level may be an ultra-low power signal having a transmission range between about 1 meter and 3 meters.
  • the level of the ultra-low power signal may correspond to the power generated by the relative movement of the trigger magnet 50 and reed switch 55 to the ultra-low power radio unit 45 .
  • Multiple point-of-care dispensers may be used in the hand hygiene event monitoring system 200 , in which case, each point-of-care dispenser may transmit a unique digital code that differentiates each particular point-of-care dispenser from the others.
  • the point-of-care dispenser 10 may be configured for mounting to a patient bed, IV unit, patient monitoring system, etc., where the particular object to which it is mounted can be moved between the predetermined zones of interest.
  • the hand hygiene event monitoring system 200 monitors dispenser usage in predetermined zone of interest.
  • the zones of interest may correspond to identified patent care locations.
  • the monitoring system 200 includes a plurality of RF transceivers that are each disposed in and associated with a predetermined zone of interest. Dispenser usage events received by an RF transceiver are associated with the zone of interest in which the RF transceiver is located.
  • Each RF transceiver is configured to receive the RF transmission events from the point-of-care dispenser in the respective predetermined zone of interest, and to transmit a further RF signal at a second power level having a range extending beyond the predetermined zone of interest.
  • the second power level may have a transmission range between about 30 meters and 60 meters.
  • One or more of the plurality of RF transceivers may be disposed at a fixed location within the respective predetermined zone of interest, such as on a wall, desk, door, etc. At least one of the plurality of RF transceivers may be: 1) a fixed point-of-care dispenser 210 , such as the one shown in predetermined zone of interest A; 2) a fixed hub 215 , such as the one shown in predetermined zone of interest B; and/or 3) a gateway 220 , such as the one shown in predetermined zone of interest C.
  • ultra-low power radio unit 45 may be a transceiver, in which case the fixed location point-of-care dispensers, hubs, and gateways that make up the monitoring system network may have the ability to receive and acknowledge the short-range messages that the point-of-care dispensers 10 transmit. It may be advantageous for fixed point of care dispensers to identify events received from portable dispensers to transmit those events rather than an event from a fixed point of care dispenser which transmit at the second power level and should not need to be again transmitted by another fixed point of care dispenser.
  • the dispenser usage event data transmitted by a point-of-care dispenser and captured by a fixed location device can be assigned to the predetermined area of interest associated with the fixed location transceiver. This may be achieved by appending the point-of-care dispenser usage event data with the specific identification of the fixed location device before transmitting it on through the rest of the system.
  • the point-of-care dispenser 10 has a unique identifier in its transmission
  • the unique identifier of the fixed location transceiver is appended to the unique identifier of the point-of-care dispenser before transmitting it to the rest of the system.
  • Hand washing event data is transmitted from the higher power transceivers in each of the predetermined zones of interest to one or more of: 1) a GSM 230, 2) a gateway 220 , and/or 3) a hub 215 , to one or more computers 245 .
  • Computer 245 may communicate the event data to computer 250 , where it is compiled into a format suitable for use by the healthcare facility.
  • the point-of-care dispenser usage data may be handled by the network in the same way as fixed dispenser usage data and pushed through to a data collection server.
  • the dispenser usage data from both the wall mounted dispensers and the point-of-care dispensers can then be assigned to the relevant predetermined area of interest and used in the hand hygiene compliance calculation for that area.
  • FIGS. 6-12 are examples of various elements of a point-of-care dispenser 10 that includes security features that address issues such as theft of the hand hygiene cartridge 25 .
  • FIG. 6 shows the point-of-care dispenser 10 in the open position with the hand hygiene cartridge 25 loaded in a chamber of the main body 15 .
  • the hand hygiene cartridge 25 is inserted into the main body 15 in the direction of arrow 305 .

  • a key 325 is used to unlock the point-of-care dispenser 10 .
  • Attempts by an unauthorized individual to pry the dispenser cover 20 from the main body 15 causes the locking elements to engage one another more firmly and with greater force thereby thwarting theft of the hand hygiene cartridge 25 .
  • the locking features of the main body 15 include locking arms 350 disposed at an upper portion of the main body 15 on opposite sides of the chamber used to hold the hand hygiene cartridge 25 .
