Description

The invention relates to a visualization system for visualizing time intervals and hygiene devices according to the features of the independent claims.

Systems to improve hygiene, especially hand hygiene, are of particular relevance in connection with the Covid-19 pandemic in order to reduce the spread of viruses and other microorganisms in a timely manner. The support of people in carrying out their own hygiene activities plays an important role.

From the JP3156354U a hand washing time recording device is known in which an elapsed period of time after activation of a proximity sensor is displayed in the manner of a digital clock. However, the temporal orientation achieved in this way is not adapted to the human visual perception system due to the digital representation.

The object of the invention is to provide a visualization system and a hygiene device to give a person better time orientation about the time required for effective cleaning of body parts, in particular for disinfection, which are simple and inexpensive and can be installed with little effort. The body parts mentioned are especially hands.

The object is achieved with the features of the independent claims.

In the visualization system for the visualization of time intervals for a user of a hygiene device, in particular a wash basin, comprising a sensor device with at least one sensor for detecting actions associated with the hygiene device, for example washing hands, an optical display device with optical display elements and a control unit with means for Receiving and evaluating the signals of the sensor device and having means for controlling the optical display device, as well as time measuring means, it is provided that the optical display elements are arranged like traffic lights, a time measurement can be triggered depending on the evaluation of the signals at a start time, the Control unit comprises means for activating the optical display elements in accordance with a time that has elapsed since the start time and for

• - Display of a first time sub-interval by activating a first group of display elements,
• - Subsequent display of a second time sub-interval by activating a second group of display elements,
• - Subsequent display of a third time sub-interval by activating a third group of display elements,
• - as well as for a termination of the activation of the optical display elements at the latest at a predetermined end time or, if necessary, at an earlier time.

In the visualization system according to the invention, the physical conditions of human perception and the reception of information are taken into account during the visualization. According to the invention, the type of visualization is aimed at improving the user's perception of the information shown in a certain way and making it expedient, with different time periods being visualized qualitatively and quantitatively. The display elements are preferably arranged horizontally or vertically in a row like traffic lights and are activated successively one after the other.

For example, a user is supported when washing his hands by the display elements, which are arranged like traffic lights and are activated in such a way that a period of time that has elapsed since the start of the washing process is displayed. It also shows the amount of time necessary to achieve adequate disinfection and thus preferably adequate protection against viruses, bacteria, etc. in accordance with guidelines, for example from the WHO or the Robert Koch Institute.

According to the invention, a first time sub-interval is initially displayed by activating a first group of display elements. The first partial interval corresponds to an insufficient time span of hand washing. The first group can have 3 display elements, or more or less.

A second time sub-interval is then displayed by activating a second group of display elements, which corresponds to a period of time during which a certain, although better but not yet sufficient, effect of using the hygiene device has been achieved. The second group can have 3 display elements, or more or less.

Subsequently, a third time sub-interval is displayed by activating a third group of display elements, the activation of the display elements in this case corresponding to a sufficient period of time for the associated disinfection. The third group can have 3 display elements, or more or less.

When the activation is complete, the display elements go out.

The optical display elements are extinguished at the latest at a predetermined end time, which corresponds to a predetermined total time period for effective disinfection.

If necessary, the activation of the optical display elements is ended at an earlier point in time if the actions of use are interrupted or ended at an earlier point in time, which is before the predetermined end point in time.

It goes without saying that, in principle, the invention also includes a system with a display device with display elements arranged in the manner of traffic lights for displaying two or more than three time sub-intervals.

Another embodiment of the invention provides that activated display elements are designed to display a traffic light configuration of at least three different colors, in particular to display the colors red, yellow and green, and / or that activated display elements have at least one continuous and / or flashing May have display state.

When displaying a traffic light configuration, it is advantageous to focus on the conditioning of people who have experience with normal traffic lights and who therefore spontaneously say “no go” at a traffic light with the color red, with the color yellow “stay alert” and with the color green “ go “have neural associates.

The user's perception process can be further supported by a continuous and / or flashing display state of the activated display elements.

It goes without saying that the sensor of the sensor device can be designed as an acoustic, optical and / or movement sensor, depending on the environmental situation during the act of use.

The use action is preferably registered by the control unit during the entire period since the start time of the system. Accordingly, after completion of the act of use, an associated appropriate acoustic signal, an electromagnetic signal and / or an optical signal is output. If, for example, an acoustic signal or a voice output “Thank you” occurs from a loudspeaker after the specified end time has been reached, the probability of correct execution of the usage action is increased.

In a further embodiment of the invention it is provided that the control unit comprises means for outputting an acoustic signal, an electromagnetic signal and / or an optical signal depending on the time elapsed since the time measurement was triggered and / or the evaluation of the signals from the sensor device.

In a further embodiment of the invention it is provided that the control unit has means for recognizing a predetermined effect of the usage actions on predetermined body parts of the user and for outputting an associated diagnostic signal.

In this case, the control unit can advantageously provide an output of a diagnostic signal diagnosing the use action, so that an assessment of the effect of the use action and a corresponding motivation of the user can take place.

In a further embodiment of the invention it is provided that the output signal from a communication tool, in particular a mobile phone, for example a smartphone with a assigned app can be added and, if necessary, can be fed to further processing means. This results in a further possibility of utilizing the information about the usage actions that have taken place. If necessary, the processing means can provide storage for the user and a preferably anonymized transmission of the corresponding data to a corresponding monitoring device.

In a further embodiment of the invention it is provided that the further processing means enable contact to be made with the user, in particular to activate a reward system.

By contacting the user, he can be motivated to behave appropriately in relation to the hygiene requirements to reduce the spread of viruses. In particular, a reward system is suitable that rewards adequate behavior, for example by awarding points or participating in a competition, in order to multiply the social impact of the visualization system according to the invention.

The components of the system, in particular the display device, can be arranged in the vicinity, in particular an already existing hygiene device in the field of view of a user. Existing hygiene facilities can therefore advantageously be retrofitted. Likewise, newly created hygiene facilities can be equipped with a system according to the invention.

In a further embodiment of the invention it is provided that the sensor device, the optical display device and the control unit are arranged in a housing with a cover part and a base plate, which are preferably connected to one another by releasable connecting means. Such an arrangement in a housing is expedient for various reasons, in particular to protect the sensor device, the optical display device and the control unit, as well as the accessibility for carrying out adjustment measures.

In a further embodiment of the invention it is provided that the system comprises an interface that can be assigned to an input element, with a receiving module which can receive signals transmitted by the input element, the control unit being programmable as a function of the signals from the input device.

The programmability of the control unit by means of signals from the input device can considerably simplify handling, because manual manipulations on the system are not necessary.

In a further embodiment of the invention it is provided that a hygiene device comprises a visualization system according to the invention, wherein the hygiene device contains a wash basin with a dispenser unit for dispensing water and / or a preferably disinfecting detergent.

The hygiene device has the corresponding advantages of the visualization system according to the invention.

In a further embodiment of the invention it is provided that a hygiene device comprises a visualization system according to the invention and the hygiene device is a tooth-cleaning tool, for example a toothbrush. The hygiene device can advantageously also be used to motivate people to use a toothbrushing tool adequately, the toothbrushing tool itself not needing to have a time control.

Further advantages and features of the invention emerge from the dependent claims and the following description of preferred examples.

The invention is explained in more detail below using the exemplary embodiments shown in the figures. If the singular or indefinite article is used in the description or in the claims, this also refers to a plurality of these elements, unless the overall context clearly indicates otherwise.

The visualization system is also referred to in the following as "Hand Hygiene Ampel" HHA.

One in the 1 to 3 shown housing 104 the HHA is preferably mounted in the vicinity of a washbasin, not shown, so that a user can access the display elements 101 , 102 , 103 when washing your hands. The display elements designed as LEDs 101 , 102 , 103 are arranged in a row. In principle, there is also a different arrangement of the display elements 101 , 102 , 103 possible.

casing

The case 104 of the HHA consists of two parts, a cover with side walls above, below, right, left, front and a rear wall 303 as well as a base plate 202 . The back wall 303 can on the wall 301 attached to the base plate 202 all components of the HHA are attached. Back wall 303 and base plate 202 are firmly connected to each other. The display elements are labels 109 assigned arranged on the cover.

The cover can be opened by pressing pressure points 105 from the back wall 303 be solved.

2 shows an interior view of the housing 104 with the control unit 205 , a sensor 107 , a loudspeaker 108 , an initialization switch 203 , a configuration switch 110 and a power supply 201 . There is also an adjustment regulator 204 to adjust the sensor 107 shown. The named components are through electrical connections 206 , 207 , 208 , 210 , 211 , 212 electrically connected.

After installation and adjustment, as shown below, the HHA is ready for operation.

The basic function and goal of the HHA is to support a person in washing their hands and to inform them of the length of time that has elapsed since the start of the washing process and what time is necessary to ensure adequate disinfection and thus insufficient protection according to the WHO / RKI guidelines against viruses, bacteria, etc.

Process trigger - start of the visualization of the measurement

Depending on the variant of the HHA, the visualization of the time measurement can be triggered either by the acoustic noise of a running water tap (variant 1) or by the hand movement of the user in the wash basin (variant 2). The triggering element is from a sensor 107 perceived.

Variant 1: Control via acoustics

In this variant, an acoustic sensor is built into the HHA. This sensor 107 responds to the sound of a tap running. The principle of speech recognition can be used here, ie the sensor 107 reacts when he hears a sound he is familiar with. The common noises of a running water tap are already stored in the HHA, in addition, the user in particular has the option of storing his own noises in the HHA, i.e. recording the sound of his own tap in the HHA.

Variant 2: Control via infrared or ultrasonic motion detectors

If, due to the circumstances, for example high acoustic background noises, too many background noises, many washbasins next to one another, acoustic control is not possible, variant 2 is an optical sensor 107 built-in, which reacts as soon as the user moves their hands in the sink or passes close to the HHA. As a sensor 107 Either an infrared motion sensor or an ultrasonic motion sensor is provided here.

Time visualization

• • Leuchte 1-3 rot (101)
• • Leuchte 4-6 gelb (102)
• • Leuchte 7-9 grün (103)

After the measurement process has been triggered, the time measurement is visualized by a series of 9 LED lights. The lights are arranged from left to right. 3 different colors are used:

• • Light 1-3 red (101)
• • Light 4-6 yellow (102)
• • Light 7-9 green (103)

For example, each lamp can have three different states: switched off, flashing or switched on.

• Die LED-Leuchte ist
  • • ausgeschaltet (-)
  • • blinkend (B)
  • • eingeschaltet (+)

After 31 seconds, you will hear an acoustic signal or a voice output “Thank you” from the loudspeaker 108 .

All lights go out after 33 seconds.

Ending the washing process early

• Möglichkeit 1: Ausgabe der Zeit in Sekunden: „Ihre Waschzeit betrug x Sekunden“
• Möglichkeit 2: bis zu eine Waschzeit von 20 Sekunden: „Sie haben den Waschvorgang zu früh abgebrochen“, ab der 20 Sekunde „Vielen Dank“
• Möglichkeit 3: keine Sprachausgabe
• Möglichkeit 4: Individuell an die Bedürfnisse des Kunden angepasste Sprachausgabe

The HHA registers the movement of the hands by means of the motion detector during the entire washing process 107 . If the washing process is ended before the end of the 30 seconds, various acoustic voice prompts can occur:

• Option 1: Output of the time in seconds: "Your washing time was x seconds"
• Option 2: up to a washing time of 20 seconds: "You stopped the washing process too early", from the 20 second "Thank you"
• Option 3: no voice output
• Option 4: Voice output individually adapted to the needs of the customer

The various options can be selected for or by the user via the configuration switch, depending on individual requirements 110 can be set. In schools, for example, option 2 is more likely to be used in order to obtain an educational effect, in offices more option 1 or 3.

Regular end of the washing process

If the entire washing process is carried out over the 30 seconds, there is an integrated Bluetooth function, WLAN or NFC to get in contact with the user, e.g. send a message. Such a reward system can be designed individually according to the wishes of the user.

It goes without saying that the time periods can also be selected differently from the time periods given in the example.

Installation and fastening

The HHA can be placed on a solid floor or on a wall 301 attached. Attachment to a wall 301 is possible, for example, by using a double-sided adhesive strip or by permanently installing the wall bracket 302 on the wall 301 The housing is then placed in this wall bracket 104 the HHA is attached.

adjustment

Via the adjustment controller 204 can increase the sensitivity and fault tolerance of the sensors 107 , for example the acoustic (variant 1) or motion sensor (variant 2) can be set. The adjustment is necessary in order to adapt the HHA to the corresponding environmental conditions such as background noise, lighting conditions, etc. It should be avoided that, on the one hand, incorrect triggering is provoked by a setting that is too sensitive, and on the other hand, the process of visualization is not triggered by a setting that is too restrictive.

The system can also have an interface that can be assigned to an input element, with a receiving module which can receive signals transmitted by the input element, the control unit 205 programmable as a function of the signals of the input device and the system is thus adjustable.

Initialization switch for acoustic recognition

Various noises from various running water taps are already stored in the HHA, which serve as a trigger for the visualization process. Under certain circumstances, the conditions at a customer are so special that it is necessary to record the special noise of this running tap once and store it in the HHA. After the deposit, the HHA reacts to the special sound of this tap running. An initialization switch is used for recording 203 pressed for 10 seconds with the tap running, this will save the sound in the HHA.
