State of the art

In all areas of human and veterinary medicine as well as in the food or pharmaceutical industry and animal breeding, the hands of the staff or of the employees are the most important carriers of pathogens. Consistent hand hygiene is therefore one of the most important measures for the prevention of infections and diseases in hospitals, nursing homes, medical, veterinary or dental practices and in the food or pharmaceutical industry as well as in animal breeding companies.

An effective hand hygiene consists of the hand washing, or the germ reduction on the skin surface by mechanical means, and the disinfection, which leads to the targeted killing or damage of certain microorganisms. Depending on the situation, it may be sufficient to perform a purely hygienic hand disinfection in which the transient (temporarily present on the skin) flora of the hands (especially pathogenic bacteria) are eliminated. In order to achieve almost complete sterility, in the surgical hand disinfection in addition to the transient flora and the resident (normal) flora of the hands can be reduced.

In order to achieve the desired effect of hand hygiene, the procedures to be carried out on hand washing or hand disinfection are in different nationally and / or globally recognized and harmonized rules or legal regulations (eg standards). Apart from certain requirements on the material composition of the cleaning or disinfecting liquid, defined rubbing procedures are also performed on the hands, which require an exact chronological sequence of different rubbing movements. In order to guarantee consistent compliance with these standards, in addition to the dispensing devices or dispensers for the cleaning or disinfecting liquids, the rubbing procedures to be performed are shown and described, for example, on posters. Also known are dispensers that provide the user with the relevant information and instructions on the rubbing procedures on an integrated display device or via a built-in speaker.

The US Pat. No. 6,375,038 B1 (Daansen et al. ) describes, for example, a dispenser which automatically senses a user by means of a non-contact sensor and, after delivery of the liquid in accordance with an instruction sequence programmed in a microprocessor, transmits instructions to the user via three light-emitting diodes.

Subject of the EP 0 914 055 B1 (Ecolab Inc.) is a dispenser that automatically perceives the user and then provides sound-assisted and / or visual information, particularly regarding the correct use of the dispensed liquid.

Although such known dispensers simplify compliance with hygiene standards, they are not completely satisfactory. Thus, most prior art dispensers are designed for a single type of detergent or disinfectant. If another cleaning or disinfecting agent is used, which usually also requires a different instruction sequence, the dispenser must be reprogrammed accordingly, if that is possible at all. However, the reprogramming is error-prone and so there is always the danger that a dispenser does not output the instruction sequence associated with the dispensed liquid. Alternatively, separate dispensers can be purchased for each cleaning or disinfecting agent. This solution is expensive and error-prone. Namely If the wrong cleaning or disinfecting agent is used in a dispenser, the dispenser will unnoticeably output the incorrect instruction sequence.

document US 2005/0127090 discloses an automatic dispenser or method having the features of the preamble of claim 1 and claim 12, respectively.

Presentation of the invention

The object of the invention is therefore to provide a dispenser associated with the aforementioned technical field, which ensures compliance with hygiene regulations and is also flexible.

The solution of the problem is defined by the features of claim 1 and of claim 12. According to the automatic dispenser of the invention, a plurality of instruction sequences, each assigned to a different identifier from different interchangeable containers, are stored in a first data memory, wherein the control unit is designed so that during and after the dispensing of the liquid by the conveyor due to a signal of the sensor for reading Identification of the replaceable liquid container retrieves an instruction sequence associated with the liquid container from the first data memory and output via the output device.

Such a dispenser has the significant advantage that it can be used for various liquid containers, which, for. B. contain different liquids, can be used without having to manually reprogramming the dispenser when changing between the different liquid containers. This will cause false manipulation, such. B. the wrong assignment of an instruction sequence to the inserted liquid container, greatly reduced. In order to guarantee a maximum of security, the identification of the inserted liquid container is also preferably read at each liquid dispensing and retrieved the matching instruction sequence and output via the output device. Should the liquid container have an identifier unknown to the dispenser, the controller of the dispenser may issue a warning message via the dispenser and / or, if there is a corresponding connection between the dispenser and the controller, prevent the dispensing of liquid from the unknown liquid container.

The liquid containers which are intended for use in the dispenser according to the invention can be, for example, liquid or gel-like cleaning agents (eg. Soaps or special disinfecting soaps) or disinfectant solutions. About the identification of the liquid container, the exact use of the liquid soap or the disinfectant solution can be specified. It is also possible, two liquid containers which contain the same liquid, for. As a disinfecting solution to identify different for different applications. Thus, for example, the disinfection of the hands in an operating room of a hospital and a patient room with the same disinfectant solution but according to different nationally and / or globally recognized and harmonized rules or legal regulations (eg standards) to perform. These methods then differ, for example, by the exact chronological sequence and intensity of the different rubbing movements of the hands. For example, a disinfectant is only authorized for sale if precisely defined requirements are fulfilled in special test methods according to their virucidal, bactericidal and / or fungicidal activity. The test procedures must be carried out by an independent laboratory which assesses the exposure time needed to achieve the effect. During the application of the disinfectant, this exposure time must be strictly adhered to. Among other things, the dispenser according to the invention guarantees that the prescribed exposure times are maintained.

The at least one non-contact proximity sensor, which serves to detect a hand of the user, also has the advantage that the user does not have to touch the dispenser for cleaning and / or disinfecting the hands. This further facilitates compliance with hygiene standards or standards.

In particular, the dispenser according to the invention guarantees a simple and secure change of liquid containers, which is of great importance, in particular in the hospital sector, since all cleaning and / or disinfecting processes of the hands are carried out in nationally and / or globally recognized and harmonized rules or legal regulations (eg. Standards) and compliance is crucial for the well-being of staff and patients. Incorrectly assigned washing and / or cleaning instructions can have serious consequences here. It also offers the inventive dispenser a great flexibility, since it can be designed for different types of liquid containers. The purchase of a variety of different dispensers, which are designed only for a single liquid container, thus eliminating.

The sensor is preferably designed to detect a hole coding, so that a perforated strip of the liquid container attached as a marking can be read out. Hole codings are particularly simple and inexpensive to produce, since only at predefined locations of the perforated strip holes must be punched. With a 4-bit hole coding (or 4 juxtaposed hole areas), for example, 15 different markings for the liquid container can be realized. The holes of the hole coding can be of any shape. In particular, rectangular, square, triangular or polygonal holes may also be suitable. If the liquid container is present, for example, as a flexible bag, the perforated strip z. B. be integrated directly into a hem or an edge region of the bag. It is also possible, for example, to provide notches as holes in the edge region, so that z. B. a comb-like edge area serves as a perforated strip. The indentations can have a rectangular, square, triangular or polygonal shape and also have rounded corners.

However, it is also possible to attach the perforated strip or the hole coding to secondary packaging means. Secondary packaging means are, for example, wrappings of cardboard or plastic, which surround the flexible bag for protection purposes. The holes z. B. can be stamped directly into edge regions of the envelope or separate tape strips are attached to the enclosure.

Basically, however, other sensors are conceivable which z. B. for identifying radio waves (RFID) mounted on the liquid container radio wave transmitter (RFID chip) are designed. Likewise, optical sensors can be used to read a barcode attached to the liquid container. The different possibilities of coding can also be combined with each other.

In particular, the sensor comprises a plurality of light barriers arranged side by side, the light barriers being designed to receive the perforated strip of the liquid container. Preferably, the receiving device for the liquid container is designed so that the hole strip comes automatically to lie between the light barriers when inserting the liquid container. The photocells then enable the optical readout of the hole coding of the perforated strip. The optical readout has the particular advantage that the readout of the hole coding can be completely contactless. This makes it possible to dispense with mechanical parts which show signs of wear over time.

In principle, however, it is also possible to read out the hole coding of the perforated strip by a purely mechanical sensor. For example, a sensor comprising a plurality of pins, which engage as mechanical probes in the open holes of the punched tape and are retained in closed areas of the punched tape, may be used. Similarly, sensors in the form of electric paper tape readers can be used, wherein the engaging in the holes of the tape strip pins additionally make electrical contact.

Advantageously, the receiving device for the replaceable liquid container at least two asymmetrically arranged and / or different diameter fasteners, in particular circular holding pins, on. These are provided for positive engagement in receiving openings of a fastening device of the replaceable liquid container and ensure a clear arrangement of the replaceable liquid container in the dispenser. Circular retaining pins with different diameter represent a particularly simple variant for the defined attachment of the liquid container. The fastening device of the liquid container has correspondingly different sized circular receiving holes or receiving holes in this case. The outer diameter of the retaining pins in the receiving device of the dispenser are approximately equal to the diameters of the circular receiving holes or receiving holes in the liquid container. This avoids, in particular when labeling the liquid container in the form of perforated strips, that the perforated strip is read from the wrong side. The danger of a wrong assignment of an instruction sequence to a liquid container we thus prevented. But it is also possible, for example, to provide retaining pins and receiving openings with different shapes. Thus, for example, a cross-sectionally round and a cross-sectionally rectangular retaining pin may be attached to the dispenser. Accordingly, the receiving holes of the liquid container are also round and rectangular shaped, which also ensures a clear arrangement of the liquid container in the dispenser.

If the fastening devices of the liquid container are in the form of receiving holes, it is also advantageous to install them in the same region of the liquid container as the perforated strip. In this case, the required holes for the punched tape and the receiving holes in a single step, for. B. by a corresponding punching machine, running. First of all, this simplifies the production process considerably. Secondly, this ensures that the distance between the receiving holes and punched tape or the relative arrangement of all the holes to each other is constant, even if the absolute position to the liquid container varies slightly. This ensures, among other things, that the perforated strip is always optimally aligned with the sensor when receiving the liquid container.

In asymmetric fastening devices can also liquid container with any external shape, such. As bags used. Liquid containers in the form of bags are particularly economical to produce, since no complicated geometric external shapes must be produced and the material requirement can be kept low.

But it is also possible to provide symmetrically formed fastening devices. In this case, an unambiguous arrangement of the liquid container in the dispenser can be achieved for example by an asymmetrical outer shape of the liquid container, which z. B. makes it impossible to close a cover or a door of the dispenser incorrectly inserted liquid container. Likewise, the sensor for reading the identification of the liquid container may be mounted laterally, so that when inserted wrong Liquid container the marking is not directed to the sensor or can not be read by the sensor.

A liquid crystal display is preferably provided as the output device, which has in particular at least 1024 separately controllable pixels. This makes it possible to output areas of abstraction in the form of texts and images and / or symbols. Instructions in the form of texts and images are particularly easy and intuitively understandable for the user, so that the risk of misunderstood instructions is greatly reduced. In addition, complex instructions for the user can be displayed in an easily understandable manner, in particular with images, so that, for example, B. the user can be instructed in the sometimes very hectic and time-critical hospital operation in the shortest possible time. Furthermore, for example, patients or other users in an operating room or a meeting room are not disturbed by acoustic signals. A possibly perceived as obtrusive spoken instruction output via a speaker is thus avoided. The number of at least 1024 separately controllable pixels also ensures that sufficiently detailed images and / or symbols can be displayed.

However, it is also possible in principle to provide other visual output devices for optical visualization. Thus, for example, displays consisting of a plurality of organic light-emitting diodes (OLED) can be used. It is also within the scope of the invention to mount a tube-based screen as an output device. In addition, output devices with less than 1024 pixels can be used, but then less detailed and thus less meaningful images and / or symbols can be displayed.

Also suitable as output device are a plurality of chronologically successive and separately controllable light-emitting diodes, which are arranged next to different pictograms. This represents a particularly cost-effective output device. The light-emitting diodes can also be present as organic light-emitting diodes (OLED).

However, in addition to the visual output devices, it is also possible to have a sound-supported output device, for example a loudspeaker, on the dispenser to install. Thus, instructions can be issued in the form of spoken text.

Preferably, the dispenser has at least one control button, which is connected to the control unit of the dispenser. For example, you can use the control buttons to turn the dispenser on or off, or to set the current system time and date. It is also possible to adapt display options or the output format of the instructions on the output device to user-specific preferences. Thus, for example, the language of the instruction sequences can be changed or the brightness and the contrast of the output device can be set. Advantageously, the user can also store parameter sets in a data memory of the control unit and retrieve them at a later time. However, the control buttons are connected to the control unit so that a modification of the instruction sequences is not possible. This is achieved, for example, by providing a second and separate data memory for the instruction sequences in the control unit, which can not be influenced by the at least one control key. In this variant, the control unit thus comprises at least two independent data memories.

For example, to obtain user-specific preferences in the event of a power failure, relocation of the dispenser, and / or battery replacement, the dispenser controller may be connected to a separate battery, accumulator, or capacitor that provides the required power. However, it is also possible to provide as data storage for the user-specific preferences a flash memory which can store the information persistently (non-volatile) without permanent power and / or power supply.

Advantageously, an electromechanically driven plunger and a support surface opposite this are arranged as parts of the conveying device in the dispenser. If a flexible outlet pipe communicating with the liquid container is arranged between these two elements of the conveying device, the flexible outlet pipe can be elastically deformed with the tappet and pressed against the opposite bearing surface. Liquid, which from the liquid container in the Outlet tube is passed is pressed in a defined amount from an outlet opening of the outlet tube and delivered into the hands of the user. A check valve or a flap is preferably installed between outlet pipe and liquid container, so that a backflow of the liquid from the outlet pipe into the liquid container during compression is avoided. Likewise, a valve can be arranged in the region of the outlet opening of the outlet pipe, which prevents an uncontrolled and undesired outflow of the liquid from the outlet pipe. However, it is also possible to provide a sufficiently small outlet opening, so that the uncontrolled outflow of the liquid from the outlet opening is prevented purely by adhesive and / or cohesive forces in the liquid.

The plunger itself can be driven for example by an electric motor and a downstream reduction gear with cam. But it is also possible in principle to use a pneumatic drive for the plunger.

The outlet pipe can be arranged, for example, directly on the liquid container and exchanged with a change of the liquid container with this. This has the advantage that the flexible outlet tube can be made of a relatively inexpensive material, as it must be usable at most until the liquid container is completely emptied. But it is also possible to use an outlet pipe with several liquid containers, if this is sufficiently durable. In a further variant, it is also possible to provide an outlet tube which is fixedly arranged in the disepenser. However, the repeated use of an outlet pipe or a fixed outlet pipe may have the disadvantage that when changing to a liquid container with another liquid, the outlet pipe must be cleaned.

In principle, however, it is also possible, for example, to provide a rotary vane pump communicating with the outlet pipe or a rotary piston pump as a conveying device. However, the electromechanically driven plunger and this opposite supporting surface with the flexible outlet tube represent a structurally particularly simple and inexpensive conveyor device, which also greatly simplifies hygienic handling of the dispenser and an uncontrolled and unwanted evaporation of volatile Liquid components from the liquid container prevented as possible. This also ensures that the composition of the liquid in the liquid container does not change during use.

Preferably, the support surface is displaceable by a mechanical adjusting device in a direction of movement of the electromechanical plunger. In this case, the mechanical adjusting device preferably comprises a manually operable adjusting screw. Thus, the distance between the support surface and the plunger can be changed, whereby the flexible outlet tube arranged therebetween can be compressed to different degrees or elastically deformed. The more the elastic outlet tube is deformed, the greater the amount of liquid delivered. If, with the maximum deflection of the electromechanical plunger remaining the same, the support surface is brought closer to the electromechanical plunger, the amount of liquid dispensed is thus increased. Accordingly, the delivered amount of liquid is reduced when the support surface is removed from the plunger.

If the mechanical adjusting device has an adjusting screw, the amount of liquid dispensed can be set in a simple manner. A certain number of revolutions of the adjusting screw can for example be assigned to a defined forward or backward movement of the support surface, whereby a reproducible adjustment of the dispensed amount of liquid is facilitated. A rotational movement can be carried out easily, in particular with a single hand, which further simplifies the handling of the dispenser.

Since it is important in most cleaning processes that the user's hands are completely moistened and remain during the cleaning processes, users with larger hands can increase the amount of liquid dispensed. Conversely, users with smaller hands can reduce the amount of liquid dispensed so as not to unnecessarily consume liquid. In general, about 1 - 6 ml of liquid are dispensed with each delivery. It is also possible to adjust the delivery quantity to the respective product. It has been shown that with soaps a quantity of 1 - 2 ml is sufficient for almost all users. For disinfectants, the optimal amount is slightly higher, at about 3 - 6 ml.

In principle, however, it is also possible to provide another adjusting device. So it is also possible to arrange the support surface on a guide rail movable and move by hand back and forth. At the respectively desired position, the support surface can then be fixed with a clamping device, such as a clamp. It is also possible to dispense entirely with an adjustment mechanism of the support surface. In this case, the conveying device z. B. be designed so that per dispensing process, only a relatively small amount of liquid is dispensed, which is not sufficient to completely wet both hands of a user. For this, the user can trigger a dispensing of liquid several times until there is a sufficient total amount on his hands.

In particular, a respective proximity sensor is arranged on at least two opposite sides of the outlet opening of the outlet tube, so that the dispensing of the liquid from the liquid container communicating with the outlet tube can take place directly in his hands, independently of a direction of approach of the user. The arrangement of the sensors on the side of the outlet opening ensures that the hands of the user are present in the area below the outlet opening when the liquid is dispensed. Since it is sufficient to initiate the dispensing of liquid in a preferred embodiment when one of the two proximity sensors detects a hand, two proximity sensors increase the likelihood that the dispensing of the liquid takes place the first time the user attempts to do so. In conventional dispensers usually only one proximity sensor is angeorndet, so that the user must partially start several attempts to trigger the delivery of the liquid. Especially in the hospital sector, where emergency situations occur again and again and rapid action is required, two proximity sensors therefore represent a significant advantage.

In principle, it is also possible to use only one sensor, but the user may then have to move his hands back and forth several times in the area of the outlet opening until they are detected by the sensor and the dispensing of the liquid is triggered by the control of the dispenser. It is also possible, for example, the sensor in another area of the dispenser, z. B. next to the output device for the instructions to place. After the hands of the user However, the sensor must then move its hands into the area of the outlet opening. If this movement is carried out too slowly, the discharged liquid is lost.

Advantageously, the instruction sequences comprise individual instructions with timings for performing certain cleaning actions, in particular instructions for cleaning and / or disinfecting hands. In this way, individual instructions and information about the cleaning process or disinfection process to be carried out can be given to the user in real time. For example, as individual cleaning actions, such as rubbing procedures of the hands can be displayed in an animated graphic, while at the same time a progress indicator, for. As an animated clock or a progress bar, informed about the temporal progress of the currently to be carried out rubbing procedure. Thereafter, the subsequent cleaning actions of the cleaning process can be shown in further animated graphics step by step, until finally the complete cleaning process has been completed. Thereafter, the dispenser can submit more information, which the user z. B. to ask to use another dispenser. Thus, for example, a dispenser equipped with soap may prompt the user, at the end of the cleaning process, with soap, to subsequently use a dispenser with a disinfectant solution.

This represents a significant simplification in the implementation of multi-stage cleaning processes, which are to be performed frequently, especially in the hospital sector due to the rules and regulations to be observed. In particular, the user can be guided in real time, step by step through the cleaning or disinfection process, which can be additionally represented by intuitively understandable images and / or animated graphics.

In principle, it is also possible, during an ongoing instruction of a first user, to divide the output device into a left and a right half, for example on the basis of the detection of the hand of a second user. Thus, the already running instruction sequence z. B. continue on the right half of the output device, while on the left half of the output device a new started instruction sequence is output. Thus, the dispenser can be used by two users at the same time. Therefore, the second user does not have to wait until the first user has gone through the complete instruction sequence, but in principle can continue to use the dispenser shortly after delivering the liquid to the first user.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Basically, the same parts are provided with the same reference numerals in the figures.

Ways to carry out the invention

In Fig. 1 a dispenser according to the invention is shown with a substantially cuboidal housing 1 in a perspective view obliquely from the front. The housing 1 has, in the region of the front upper edge, a back-beveled surface in which a rectangular liquid-crystal display 2 is embedded. Below the liquid crystal display 2, a door 3 attached to the housing 1 of the dispenser extends over the entire lower area of the front side of the dispenser. The door 3 has an outwardly arched shape. To open the door 3, a handle 5 is also attached to the door 3 in the upper area on the right side. The front two edges of the housing 1 are chamfered in the lower half by a chamfer 6.1 increasing on the left side and in a vertical direction of the dispenser and by a right-side chamfer 6.2 formed symmetrically therewith. The door 3 has in the lower left and lower right corner two recesses, which are the two chamfers 6.1, 6.2 formed accordingly, so that a relatively smooth transition between the two chamfers 6.1, 6.2 and the door 3 is present. In the upper region of the door 3 is located in the horizontal direction of the dispenser approximately in the middle of a rectangular window 4, which allows the view into the inner regions of the dispenser with the door 3 closed. On the right side surface of the housing 1, a female connector 7 for an external power supply is further attached.

In Fig. 2 is the dispenser off Fig. 1 shown at remote door 3. The whole in Fig. 1 inside area of the dispenser closed by the door 3 is therefore visible. Below the liquid crystal display 2 is located approximately in the middle on a first inner and vertical mounting surface 25 between the two side edges of the dispenser Sensor 9, consisting of four side by side light barriers 9.1, 9.2, 9.3, 9.4. Below the sensor 9, the first attachment surface 25 has a rectangular extension 25.1, which is provided in particular as a support plate for a liquid container to be received. On the right side of the first mounting surface 25, two horizontally adjacent control buttons 10.1, 10.2 are arranged laterally above the sensor 9 for the liquid crystal display. Left of the sensor 9, a first round retaining pin 11 projects vertically from the first attachment surface 25 to the front. On the right side of the sensor 9 is a second round retaining pin 12 perpendicular from the first mounting surface 25 forward. The second retaining pin 12 points to the in Fig. 2 visible front side about a half as large diameter, as the first retaining pin 11. Below the first retaining pin 11 and the left of the rectangular extension 25.1 protrude two electrical contacts 22.1, 22.2 of the dispenser vertically downwards. These are connected to two battery contacts 23.1, 23.2 of a parallelepiped-shaped battery 27, which projects downwards on the left side of the rectangular extension 25.1. On the left next to the rectangular extension 25.1, a first mounting hole 24 concealed by the battery 27 is inserted in the rear wall 1.1 of the housing 1. Right next to the rectangular extension 25.1, a second mounting hole 26 is also inserted into the rear wall 1.1 of the housing 1. The two mounting holes 24, 26 are formed identically and provided for attachment, for example with screws, the dispenser to a wall or other third element.

The battery 27, which serves the power supply of the dispenser, rests on a first shoulder 16.1, which is in the horizontal direction or perpendicular to the rear wall 1.1 of the housing 1 forward (out of the image plane). At the front edge of the first paragraph 16.1 a downwardly and forwardly inclined surface 16.3 is mounted, which protrudes with its lower portion between the upper portion of the two chamfers 6.1, 6.2 of the housing 1. At the lower edge of the inclined surface 16.3, a second paragraph 16.2 is mounted, which is also formed perpendicular to the rear wall 1.1 of the container 1 and therefore arranged coplanar to the first paragraph 16.1. However, the second paragraph 16.2 is located in a direction perpendicular to the rear wall 1.1 of the dispenser before the first paragraph 16.1. The two paragraphs 16.1, 16.2 and the oblique Surface 16.3 therefore have an armchair shape. (in Fig. 5 the arrangement is given in a profile view).

Below the second paragraph 16.2 and starting at the front edge, a second vertical mounting surface 38 between the two chamfers 6.1, 6.2 of the housing is arranged. The second attachment surface 38 is disposed approximately in the same plane as the first attachment surface 25 (see also Fig. 5 ). Approximately in the region of the center of the mounting surface 38 is a ten-axis adjusting screw 20 from the mounting surface 38 perpendicular to the front. Every second of the evenly formed ten corners of the adjusting screw 20 is provided with a punctiform marking.

3 and 4 show a flexible bag 13 as a liquid container, which, for example, with a disinfectant solution 15 (eg., A mixture of povidone-iodine, chlorhexidine, ethanol, iso-propanol and / or n-propanol) is equipped. The bag 13 is intended for single use and consists for example of a tubular plastic film, which has an elliptical cross-section. In this case, the upper end of the tubular plastic film is welded to an upper rectangular edge region 8 and the lower end to a lower rectangular edge region 50. In the upper rectangular edge region 8, a first circular attachment hole 53 is introduced on the left side. This corresponds in diameter approximately to the in Fig. 2 recognizable diameter of the first retaining pin 11. On the right side, a second circular attachment hole 54 is accordingly introduced in the upper rectangular edge region 8. The diameter of the second attachment hole 54 is approximately half the size of the diameter of the first attachment hole 53 and therefore approximately corresponds to the diameter of the second retention pin 12 Fig. 2 , The two mounting holes 53, 54 in the upper edge region 8 are therefore provided for fastening the bag 13 to the two retaining pins 11, 12, wherein the different diameters of the mounting holes 53, 54 and the retaining pins 11,12 ensure a defined arrangement of the bag 13 in the dispenser ,

The area in the middle between the two mounting holes 53, 54 is formed as a perforated strip 51 which extends over a total of four in the horizontal direction arranged side by side and designated by cross-type marks columns 51.1, 51.2, 51.3, 51.4 has. The areas of the four columns 51.1, 51.2, 51.3, 51.4 can either be closed or substantially impermeable to light for marking the bag 13, or else have a perforation which allows the passage of light. Due to the different combination possibilities of permeable and closed columns, fifteen different identifications of the bag 13 can be realized with the four columns 51.1, 51.2, 51.3, 51.4. Is concrete in Fig. 3 a view from the left first column 51.1 of the perforated strip closed. The second column 51.2 of the perforated strip 51, viewed from the left, is also closed. On the other hand, the third column 51.3 viewed from the left has a perforation 52 in the form of a punched-out and circular hole. The last column 51.4 viewed from the left is in turn closed like the first column 51.1.

Below the upper edge region 8 is in the upper half of the bag 13 at the front about in the middle of a label 14 with information on the bag 13 and the disinfectant solution 15 therein glued. If the bag is used in the dispenser, the label 14 is visible through the rectangular window 4 of the dispenser even when the door 3 is closed.

In the lower half of the bag 13, an annular connecting element 17 is arranged lying flat above the lower edge region 50. The annular connecting element 17 has on the outer side a thread, which is provided for screwing an outlet pipe.

The Fig. 5 shows the interior of the dispenser Fig. 1 and 2 from the left side with the left side wall removed. In this case, the bag 13 is made 3 and 4 used in the dispenser. The first retaining pin 11 is inserted in the first mounting hole 53 of the bag 13, so that it is held at the upper edge region 8 hanging down. A first projection 32.1 on the inside of the door 3 presses the bag 13 above the window 4 to the mounting surface 25. Below the window 4, a second projection 32.2 is attached to the inside of the door 3, which the bag 13 against the rectangular extension 25.1 of Mounting surface 25 presses. The area of the perforated strip 51 of the bag 13 is between the U-shaped sensor 9, so that the four columns 51.1, 51.2, 51.3, 51.4 of the perforated strip 51 are each arranged in front of one of the four light barriers 9.1, 9.2, 9.3, 9.4. The four light barriers 9.1, 9.2, 9.3, 9.4 then allow the determination of the state (open or closed) of the four columns 51.1, 51.2, 51.3, 51.4 in a simple manner.

Directly above the sensor 9, a control unit 29, consisting of a microprocessor and a data memory on a printed circuit board 29 1 is arranged. The control unit is connected via an electrical cable 28 to the sensor 9. Likewise, the control unit 29 by a in Fig. 5 not shown electrical cable connected to the motor control 43 (see also Fig. 6 ).

At the connecting element 17 of the bag 13, which forms the lowermost portion of the inserted bag 13, a flexible cylindrical outlet pipe 19 is attached. The connecting element 17 is just above the second paragraph 16.2. The outlet pipe 19 is defined by a in Fig. 5 invisible opening guided by the second paragraph 16.2 and protrudes in a vertical downward direction from the bottom 1.2 of the dispenser out. The outlet tube 19 has at the upper end an annular fastening screw 18 with internal thread, which is screwed to the thread on the outside of the connecting element 17, so that the outlet tube 19 is secured to the bag 13. Since the bag 13 is pierced and / or cut open during attachment of the outlet tube 19 to the connecting element 17 in the central region of the connecting element 17 by a cutting edge projecting upwards inside the outlet tube 19, the bag 13 and the outlet tube 19 communicate with each other. In the region of the free end of the outlet tube 19, this tapers conically and then passes into a thinner but likewise cylindrical outlet opening 21. In the region of the annular fastening screw 18, a first non-return valve (not shown) is mounted in the interior of the outlet tube 19, which prevents backflow during the liquid delivery of the disinfectant solution 15 present in the outlet tube 19 into the bag 13. In the region of the outlet opening 21, a second valve (not shown) is mounted in the interior of the outlet pipe 19, which prevents the disinfecting solution 15 present in the outlet pipe 19 from being pressed only when pressure is applied to the outlet pipe 19 Outlet tube 19 (through the conveyor) exits and does not drip uncontrolled or expires.

Below the second paragraph 16.2 a substantially U-shaped profile is arranged, which rests with its lower leg 39.2 on the inside of the bottom 1.2 and connects with its upper leg 39.1 directly to the bottom of the second paragraph 16.2. The outlet pipe 19 is characterized by in Fig. 5 invisible holes in both legs 39.1,39.2 of the U-shaped profile 39 performed by this. The base 39.3 of the U-shaped profile 39 is on the right side of the outlet tube 19 in a vertical orientation and parallel to this between outlet tube 19 and vertical mounting surface 38 before. By the adjusting screw 20, which is carried out from the direction of the door 3 by the vertical mounting surface 38, the U-shaped profile 39 can move in a direction from the vertical mounting surface 38 to the rear wall 1.1 of the housing 1 back or forth.

Below the first paragraph 16.1 and the inclined surface 16.3, an electric motor 33 is arranged with a vertically downwardly directed pinion 36.1 on the rear wall 1.1 of the dispenser. The pinion 36.1 drives a multi-stage reduction gear 36, wherein the last gear 36.2 drives a lever 41 in the reduction gear 36 via an eccentric cam of the last gear 36.2. The lever 41 is coupled on the last gear 36.1 opposite end via a hinge 42 to a plunger 37. The plunger 37 is mounted in an annular guide device 35. In the Fig. 5 illustrated situation corresponds to the basic position in which the plunger 37 is retracted maximally in the direction of the rear wall 1.1. The lever 41 actuates a motor switch 40 mounted behind it.

On the left next to the outlet pipe 19 protruding from the bottom 1.2 of the dispenser, between the rear wall 1.1 and the outlet pipe 19, there is also arranged a first proximity sensor 44 projecting from the bottom 1.2 of the dispenser.

When the motor 33 rotates, the plunger 37 is driven via the gear 36 and the lever 41 and moved in a direction perpendicular to the rear wall 1.1 on the door 3 and back. The plunger is arranged so that it is in the base 39.3 opposite opening of the U-shaped profile 39 is inserted and laterally on the outlet tube 19 presses. Since the outlet tube 19 is pressed against the inside of the base 39.3 of the U-shaped profile 39, the outlet tube 19 is elastically deformed. A non-visible check valve mounted in the region of the annular fastening screw 18 in the interior of the outlet tube prevents the liquid present in the outlet tube from being pushed back into the bag 13. The valve mounted in the region of the outlet opening 21 in the interior of the outlet pipe 19 opens thereby, whereby a defined amount of disinfecting solution is dispensed.

After a complete revolution of the last gear 36.2 of the transmission 36, the lever 41 actuates the motor switch 40 upon retraction of the plunger 37, whereby the motor control 43 switches off the electric motor 33 and the transmission 36 remains in the retracted basic position with the lever 41 and the plunger. This dispenses a precisely defined amount of disinfectant solution 15. Even if the user continues to leave his hands in the vicinity of the proximity sensor, there will be no new liquid dispensing. If a user requires additional disinfectant solution 15, he can remove his hands from one of the two proximity sensors 44, 46 and approach them again. In this case, disinfecting solution is again dispensed as described above.

In Fig. 6 a block diagram of the dispenser is shown. The central control unit 29 of the dispenser consists of a microprocessor 29.2, a first data memory 29.3 and a second data memory 29.4 on a common printed circuit board 29.1. In the first data memory 29.3 of the control unit 29, a plurality of different instruction sequences for the various bags 13 usable in the dispenser are stored as text and image information. The control unit 29 is connected to the liquid crystal display 2 via an electric cable 28. The control buttons 10.1, 10.2, which are also connected to the microprocessor 29.2 of the control unit 29, allow the setting of various user settings and formatting parameters that affect the representation of the instruction sequences on the liquid crystal display 2. These include z. As the brightness or contrast of the liquid crystal display 2, the language of the text information or date and time formats. Likewise, with the two control buttons 10.1, 10.2 the current time and date are set. The user settings and formatting parameters can be stored in the second data memory 29.4 and re-selected by the user with the two control buttons 10.1, 10.2 and read by the microprocessor 29.2. This makes an easy-to-understand adaptation of the instruction sequences to be output to user-specific preferences possible.

The two proximity sensors 44, 46 are connected directly to a motor control 43. As soon as one of the two proximity sensors 44, 46 detects the presence of a hand, the motor control 43 switches on the electric motor 33. This rotates until the motor switch 40 as at Fig. 5 described by the lever 41 is actuated. Then, the motor controller 43 turns off the electric motor 33.

Shortly after liquid dispensing, or after switching off the electric motor 33, the motor controller 43 transmits a signal via an unillustrated electrical cable to the microprocessor 29.2 of the control unit 29. This subsequently determines the identification or the perforated strip 51 of the bag 13 the sensor 9 and retrieves an instruction sequence corresponding instruction from the first data memory 29.3 of the control unit 29 from. On the basis of the user settings and formatting parameters read from the second data memory 29.4, the instruction sequences are formatted and then timed transmitted to the liquid crystal display 2 and displayed by this according to the user settings and the formatting parameters.

A perspective view of the arrangement Fig. 5 , with the door 3 removed from the dispenser, is in Fig. 7 displayed. Here, in particular, the second retaining pin 12 visible, which is inserted into the second attachment opening 54 of the bag 13.

Fig. 8 shows a cross section through the dispenser along the line A - B from Fig. 5 , In this case, a first slot-like opening 16.20 is introduced with rounded corners approximately in the middle of the second paragraph 16.2, wherein the longitudinal direction of the first slot-like opening 16.20 is arranged in a direction perpendicular to the rear wall 1.1. In the first slot-like opening 16.20 which is arranged below the second paragraph 16.2 to recognize circular bore 49 in the upper leg 39.1 of the U-shaped profile. The circular bore 39.1 has a diameter which corresponds approximately to the width of the first slot-like opening 16.20 of the second paragraph 16.2. Thus, the outlet pipe 19 guided and held by the circular bore 49 can rotate freely on the adjusting screw 20 through the upper leg 39.1 or through the U-shaped profile 39 along the length of the first slot-like opening 16.20 in the direction towards the rear wall 1.1 or moved back.

On the left and in parallel alignment with the first slot-like opening 16.20, a second slot-like opening 47 is also inserted in the second shoulder 16.2. Therein, an arrow-shaped pointer 34 is arranged, which is fixedly connected to the U-shaped profile 39. Upon rotation on the adjusting screw 20, the arrow-shaped pointer 34 moves in the second slot-like opening 47 with the U-shaped profile back and forth. A calibrated scale 48 to the left of the second slot-like opening 47, which ranges from 1 ml to 6 ml, indicates approximately the amount of fluid that is emitted by a movement of the plunger 37.

In Fig. 9 is a bottom view of the dispenser Fig. 5 shown. The rear wall 1.1 of the dispenser is in Fig. 8 arranged below. In the upper half of the rectangular base 1.2, the outlet opening 21 of the outlet tube 19 protrudes approximately in the middle from a third slot-like opening 45 in the bottom 1.2 of the dispenser. The third slot-like opening 45 is substantially the same design as the first slot-like opening 16.20 and also serves the free displacement of the outlet tube 19. Links below the third slot-like opening 45, the first proximity sensor 44 is mounted, while right below the third slot-like opening 45 of second proximity sensor is arranged. If the dispenser with the rear wall 1.1 attached to a third element, so are the two proximity sensors 44, 46 between the third element and the outlet opening 21 of the outlet pipe 19. This ensures that the user who the dispenser from the front, or the Rear wall 1.1 facing away from the dispenser, approaching, holding his hand under the outlet 21, while his hand from one or both the two proximity sensors 44, 46 are detected and the output of the disinfectant solution 15 takes place.

The Fig. 10a - f show a sequence of instructions or instruction procedures which assist the user in carrying out an approximately 30-second hygienic hand disinfection according to the European Standard EN 1500. The individual disinfection actions to be performed on the hands will be shown step by step and time-controlled after delivery of the disinfecting solution 15 and detection of the perforated strip 51 by the sensor 9 on the liquid crystal display 2. This instruction sequence is merely an example. If a bag with a different identification is used in the dispenser, an instruction sequence assigned to this bag is retrieved from the data memory of the controller 29 and displayed on the liquid crystal display 2.

In the Fig. 10a Information displayed on the liquid crystal display includes a first device status 100 of the dispenser in the form of a symbol representing the state of charge of the battery 27. Below a first instruction text 200 is shown, which prompts for rubbing the superimposed palms. Furthermore, a first animated progress indicator 300 informs in the form of a mixed text and symbol representation of the still to be performed frictional movements of the hands. In addition, a first animated image representation 400 of the friction movement to be performed is shown.

After about 8 seconds, the in Fig. 10b represented information displayed on the liquid crystal display 2. In this case, the updated second device status 101 is dargstellt. The second instruction text 201 requests rubbing of the palm of the first hand on the back of the hand of the second hand and vice versa. This is accompanied by the second animated progress indicator 301 in the form of a mixed text and symbol representation of the number of still-to-be-performed movements of the hands and the second animated image representation 401 of the movements to be made.

After about 11 seconds, the in Fig. 10c represented information displayed on the liquid crystal display 2. At this time, the updated third device status becomes 102 dargstellt. The third instruction text 202 prompts for the overlapping palms with crossed fingers. This is accompanied by the third animated progress indicator 302 in the form of a mixed text and symbol representation of the number of still-to-be-performed movements of the hands and the third animated image 402 of the movements to be made.

After about 19 seconds, the in Fig. 10d represented information displayed on the liquid crystal display 2. In this case, the updated fourth device status 103 is dargstellt. The fourth instruction text 203 requests rubbing the backs of the fingers of one hand against the palm of the other hand. This is accompanied by the fourth animated progress indicator 303 in the form of a mixed text and symbol representation on the number of movements of the hands still to be performed and the fourth animated image representation 403 of the movements to be made.

After about 22 seconds, the in Fig. 10e represented information displayed on the liquid crystal display 2. Thereby, the updated fifth device status 104 is displayed. The fifth instruction text 204 alternately prompts for rubbing of the right and left thumbs. This is accompanied by the fifth animated progress indicator 304 in the form of a mixed text and symbol representation of the number of still-to-be-performed movements of the hands and the fifth animated image representation 404 of the movements to be made.

After about 29 seconds, the in Fig. 10f represented information displayed on the liquid crystal display 2. Thereby the updated sixth device status 105 is displayed. The sixth instruction text 205 requests rubbing of the closed fingers of one hand on the palm of the other hand. This is accompanied by the sixth animated progress indicator 305 in the form of a mixed text and symbol representation of the number of still-to-be-performed movements of the hands and the sixth animated image representation 405 of the movements to be made.

Thereafter, the hand disinfection is completed and a corresponding message is displayed on the liquid crystal display 2.

The embodiment described above is to be understood merely as an illustrative example, which may be modified as desired within the scope of the invention.

Thus, the shape of the housing 1 of the dispenser can be chosen arbitrarily in principle. In particular, strongly rounded shapes of the housing may be suitable, since this the risk of injury when accidentally abutment is low.

Instead of the battery 27 and a battery can be used as a power source or the dispenser can be powered directly through the socket 7 by a power supply with power.

The perforated strips 51 of the bag 13 from 3 and 4 may also have more or less than the four illustrated columns 51.1, 51.2, 51.3, 51.4. The greater the number of columns, the more possible combinations and more labeling can be realized. Accordingly, the number of light barriers 9.1, 9.2, 9.3, 9.4 on the sensor 9 is adapted to the number of columns of the perforated strips.

In addition, it is also possible, instead of the flexible bag 13 to use as a liquid container dimensionally stable container. Likewise, the outlet pipe may already be permanently mounted as part of the bag 13 or the liquid container.

There may be other than those at 3 and 4 mentioned disinfectant solutions (mixtures of povidone-iodine, chlorhexidine, ethanol, iso-propanol, and / or n-propanol) are used. It is crucial that they have the best possible bactericidal, fungicidal, tuberculocidal and / or virus-inactivating effect.

It is also possible, for example, to dispense with the valve in the region of the outlet opening 21 of the outlet tube 19 and to dimension the outlet opening 21 such that the liquid present in the outlet tube 19 is retained in the outlet tube 19 due to adhesive and cohesive liquid forces and only through Pressure on the outlet pipe 19 emerges. This is especially true for liquids with higher viscosities, such as. As in some soap solutions suitable.

The two Fig. 10a - f time specified for the total time or for the individual steps of the cleaning process are dependent on the cleaning process to be performed, which in turn is determined by the bag 13 inserted in the dispenser and may vary accordingly.

In summary, it should be noted that a novel dispenser has been created which substantially simplifies compliance with hygiene standards. Furthermore Fahlmanipulationen when changing the liquid container are largely excluded with the dispenser according to the invention, since the sensor integrated in the dispenser performs an automatic recognition of the identification of the liquid container used in the dispenser at each liquid dispensing.
