Description

Field of the invention

The invention relates to a cleaning and disinfecting device for care utensils and a nozzle for use in such a cleaning and disinfecting device. Such cleaning and disinfecting equipment and such nozzles are used in particular in care institutions and hospitals to clean and disinfect care utensils with cavities for receiving larger amounts of liquid, such as care utensils, bedpans, urine bottles or other care utensils. Typical fields of application are hospitals with nursing homes and elderly care facilities. However, other applications are possible in principle.

State of the art

In care facilities such as hospitals or nursing homes, cleaning and disinfection equipment (RDGs) are used in which care utensils such as bedpans, urine bottles or other care utensils are cleaned and disinfected. These cleaning and disinfecting devices are commercially available, for example in construction versions, which have a front door, which can be opened by a horizontal axis by a pivoting movement, for example, about 90 ° to the front. However, other embodiments are possible.

Such cleaning and disinfecting devices are known from the prior art and in special embodiments, for example in DE 10 2005 026 088 A1 , in DE 103 48 344 A1 or in DE 103 52 809 A1 described. For all constructions described there, reference may be made, for example, as a starting point for the invention described below.

CH 358 548 refers to a flushing device for hygienic purposes serving vessels. It is applied to a holding device, which transfers the bedpan from a substantially horizontal to a vertical position upon actuation of a hood-shaped cover around a hinge. By means of a nozzle mimic arranged in the interior of the flushing apparatus, the interior of the bedpan can be sprayed out and flushed out. The spray nozzle is designed as an arm and comprises a number of nozzles.

To operate the washer-disinfectors usually the front door is opened to the front. The care utensils or goods to be cleaned are inserted into a holder, the so-called vessel holder. The vessel holder is fastened, for example, inside on the front door. Subsequently, the front door can be closed by an operator by means of a pivoting upward, and the operator can, for example manually, start a required cleaning program. After completion of the cleaning program and after successful disinfection, the front door can be opened so that the care utensils can be removed again. However, other types of embodiment of the cleaning and disinfecting equipment and other embodiments of the operation are basically possible.

Cleaning and disinfection devices have in most cases inside a washing chamber, in which the cleaning process takes place, one or more nozzles, which perform different functions during the cleaning process. For example, there exist nozzles which are designed for the internal cleaning of the care utensils, for example the bedpans. Alternatively or additionally, nozzles for the external cleaning of the care utensils to be cleaned can be provided. For internal cleaning of other types of care utensils, such as urine bottles, special nozzles may also be provided. These nozzles may be designed such that a jet of cleaning fluid emanating from these nozzles penetrates a neck, for example a narrow neck, of the care utensils, for example the urine bottles, and hits the bottom of the care utensils, for example the inner bottom of the urine bottles. This jet of cleaning fluid then bursts inside the bottom of the care utensils, and the cleaning fluid can wet and clean the entire interior surface of the care utensils.

However, there is the problem that, if the beam does not impinge in the prescribed manner inside the care utensils, it is likely that the care utensils are not cleaned properly. This would result in significant sanitary problems with the operator of the washer-disinfector.

However, there are different types of care utensils on the market, such as care utensils, which may differ in their materials, shape and dimensions. For urine bottles, for example, this means that the inclination of the neck of the urine bottles to the body of the urine bottles and the length of the entire bottle may differ from model to model.

To compensate for these differences and to achieve an optimal cleaning result with all care utensils, the manufacturer usually adjusts the vessel holders to the respective different requirements ex works. In extreme cases, even new nozzles have to be developed and made to fill all requirements. However, with every new customer order, this fact usually causes a great deal of effort in development, in the trial field and in production. In addition, the cost of stocking spare parts is not insignificant.

Object of the invention

The present invention is in view of the outlined disadvantages of the prior art, the object to provide a way to meet with simple means the different requirements of different types of items to be cleaned in the form of care utensils to the washer-disinfector. At the same time, the variety of parts in production and spare parts should be reduced.

Disclosure of the invention

This object is achieved by a washer-disinfector and a nozzle for use in such a washer-disinfector with the features of the independent claims. Advantageous developments of the invention, which can be implemented individually or in combination, are shown in the subclaims.

A cleaning and disinfecting device for the cleaning of care utensils is proposed. A cleaning and disinfecting device is understood to be a device which can carry out a cleaning process on the care utensils, in which the care utensils are at least largely freed from impurities adhering to the care utensils and / or impurities contained in the care utensils by means of at least one cleaning fluid can. Furthermore, the cleaning and disinfecting device should be set up to carry out at least one disinfecting process, that is to say a process in which a germ reduction of the germs adhering to the care utensils takes place. This germ reduction can be partial, but can also extend to complete microbial reduction in the context of sterilization. The disinfection process can, for example, under Use of conventional disinfection media done, especially using moist heat. For example, superheated steam can be used for the disinfection and / or a chemical disinfection and / or a thermal disinfection or a combination of the mentioned methods and / or other methods, for example a combination of thermal and chemical disinfection methods.

Care utensils are generally understood to mean utensils that can be used in the care sector for the care of human or animal patients. The term "care utensils" can be understood both individual objects and a plurality of objects. Thus, for example, a cleaning and disinfection device can be used for cleaning a single object from the area of the care utensils, or a device for a simultaneous cleaning of a plurality of such objects from the area of the care utensils can take place.

Particularly preferred is the use for care utensils, which are suitable for receiving larger amounts of waste, so care utensils, which are at least partially designed as vessels. Preferably, such vessels are vessels for a quantity of liquid and / or solid wastes in the range of a few ml to a few tens or a few 100 ml. Typical examples of such care utensils are care utensils such as bedpans, urine bottles, bedpans or the like Types of care ware.

According to the preferred embodiment for care utensils, which are provided as vessels for receiving larger amounts of liquids, and the cleaning and disinfection device for receiving such larger liquid or solid waste quantities may be suitable. For example, the washer-disinfector, such as in DE 103 48 344 A1 described, have a drain, which can be connected, for example, with a building-side drainage system. This drain can also be designed with a siphon, so that even larger amounts of solid and / or liquid waste from the care utensils can be easily disposed of, for example, amounts in the range of 100 ml or more.

The washer-disinfector includes a wash chamber for receiving the care utensils. For example, this washing chamber may in turn be configured with at least one vessel holder in order to receive the care utensils. For example, this at least one vessel holder in turn with a door of the wash chamber, for example again a hinged front door to be coupled. However, other embodiments are possible in principle.

Furthermore, the cleaning and disinfecting device comprises at least one spray system for loading the care utensils with a cleaning fluid. In particular, liquid cleaning fluids can be used, for example water with or without additives, such as detergents and / or disinfectants.

The spraying system includes at least one nozzle configured to dispense at least one jet of cleaning fluid. Under a beam is bundled, essentially in the same direction in space given amount of cleaning fluid to understand. Preferably, the solid angle in which the cleaning fluid is dispensed is less than 4 π / 10, in particular less than 4 π / 50 and particularly preferably less than 4 π / 100. The spatial direction in which this jet is emitted will also be hereinafter referred to as beam direction.

According to the invention, it is proposed to design the at least one nozzle or, if several nozzles are provided, at least one of these nozzles in such a way that the jet direction under which the jet is emitted by the nozzle is adjustable.

Preferably, the beam direction is manually adjustable. For example, the beam direction after adjustment, for example, after a manual adjustment, be fixable. For this purpose, for example, locking means may be provided, which allow a fixing in a desired position of the beam direction, ie in a certain space angle position. This locking means may, for example, in at least a first position of the locking means allow adjustment of the beam direction and fix the beam direction in at least a second position of the locking means.

The proposed cleaning and disinfection device solves the above-described object thus by the fact that the nozzle, which is provided for the cleaning of care utensils, such as the urine bottle, is designed such that the direction of the beam easily, for example during assembly and / or when commissioning the washer-disinfector, can be optimally adjusted to the requirements of the cleaning material in the form of care utensils.

For example, the nozzle may be designed in several parts for this purpose. For example, the nozzle may comprise a nozzle which has at least one bore for feeding of the cleaning fluid to the nozzle. This nozzle block may for example be fixedly mounted on an inner wall of the wash chamber.

Furthermore, the nozzle may have an adjustable nozzle head, which can ensure the above-described adjustability of the beam direction. For example, this nozzle head can be angularly movably mounted about one or more pivot axes. A gimbal bearing and / or a bearing by means of a ball joint is conceivable. At the same time, however, the nozzle head can be made lockable, so that although the angular position is adjustable in one or more dimensions, however, that as soon as the desired angular position and thus the desired beam direction is set, a fixation can be done by detecting the nozzle head.

Through at least one bore in the interior of the nozzle block, the cleaning fluid can be supplied. The jet can then be formed in the interior of the nozzle head and dispensed into the washing chamber or the care utensils in a jet direction predetermined by the position of the nozzle head. Also, a simultaneous delivery of multiple beams through the nozzle is possible, all beams in their beam directions can be adjusted simultaneously or can be separately adjustable and separately fixed. Also in this respect, the nozzle can be designed in several parts.

As described above, the nozzle may comprise a locking means, wherein, for example, in the at least one first position of the locking means, an adjustment of the beam direction is possible and wherein in at least a second position of the locking means, the beam direction can be fixed. This locking means may for example be arranged on the nozzle and / or on the nozzle head and / or at a transition between nozzle and nozzle head, for example a pivot joint. Other embodiments are possible.

The locking means may for example comprise at least one of the following devices: a screw, for example a thumbscrew or another type of screw; a sapwood; a bolt; a locking device; a detent button, in particular a spring-loaded detent button; a quick release device. Alternatively or in addition to the stated locking means, combinations of said and / or other types of locking means may also be provided. The locking means may in particular be arranged to permanently fix the jet direction during operation of the cleaning and disinfecting device. This means that even during a Operation usual vibrations or changes in ambient conditions do not significantly affect the beam direction.

It is furthermore particularly preferred if the beam direction can be adjusted over an adjustment range. For example, this adjustment range can be predetermined over a single angle in space and / or over a plurality of such angles, for example a polar angle and an azimuth angle.

It is particularly preferred if the nozzle is fixable in a plurality of predetermined positions of the beam direction. A plurality of two, three or more positions of the beam direction can be understood. For example, the locking device may have a separate catch in a uniform or uneven distance on the angle scale or the angle scales. For example, a clearly noticeable for an operator engagement of the nozzle can be done in one position. The adjustment range can be subdivided, for example, into a plurality of predetermined steps.

It is furthermore particularly preferred if the nozzle, in particular the named optional locking device, is set up in order to make a selected position of the beam direction optically recognizable to an operator. This can be done, for example, in that the nozzle, in particular the latching device, comprises a display means which indicates the selected position of the jet direction. This display means may for example be a scale on which the operator can read the respective position of the beam direction. However, other types of display means are also possible in principle, for example mechanical and / or electrical display means. A forwarding to a control of the cleaning and disinfecting device is possible, so that, for example, the position of the beam direction for an operator on a display of the controller can be made visually recognizable.

In a further preferred embodiment of the washer-disinfector, the nozzle comprises at least one fixed part and at least one adjustable part. The fixed part may be, for example, the already described at least one nozzle assembly, and the adjustable part may be, for example, the at least one nozzle head. In this case, it is particularly preferred if at least one labyrinth seal is provided between the fixed part and the adjustable part. A labyrinth seal is understood to mean a seal, in particular a contact-free seal, in which an extended sealing path is sealed by an interaction of rings or ribs and / or grooves between the two against each other Share is based. For example, the nozzle assembly and the nozzle head may each have such rings and / or grooves, in singular or in a plurality, which engage with each other, so that the sealing effect is provided by an extended sealing path.

The nozzle can be made of a variety of materials. Thus, for example, the nozzle, for example the nozzle head and / or the nozzle assembly comprise at least one of the following materials: a metallic material; a plastic. In particular, it is preferred if the nozzle is wholly or partly made by means of a shaping process in which bodies are produced directly from three-dimensional computer data. Examples of such molding processes are CNC milling, rapid prototyping, e-manufacturing or similar molding techniques.

In addition to the cleaning and disinfecting device according to one or more of the variants described above, the invention further relates to a nozzle for use in a spray system of such a washer-disinfector. With regard to possible embodiments of the nozzle, reference may be made to the above-described possible embodiments of the washer-disinfector, which relate in each case to the nozzle. The nozzle should be designed to emit at least one jet of the cleaning fluid, wherein the jet direction, under which the jet is emitted, should be adjustable and preferably fixable. For further possible embodiments, reference may be made to the above description.

The washer-disinfector and nozzle for use in a spray system of this washer-disinfector has a number of advantages over prior-art devices of this type. Thus, for example, it allows an assembler during production and / or during commissioning of the washer-disinfector to easily and quickly adapt the washer-disinfector to the particular circumstances and requirements of a customer. It is also possible to change the settings when changing the type of care harness. The setting can be done manually or automatically, for example by means of one or more drives. In this case, the adjustability may be configured such that the wash chamber has to be opened for these settings, for example by opening a front flap. Alternatively or additionally, a setting can be made by appropriate controls, for example by entering appropriate control commands in such controls. Also in this way can be done, for example, by one or more electrical and / or mechanical drives, the adjustment of the beam angle, for example, a quick adaptation to others To allow for types of care utensils. For example, a list of care utensils may also be stored in a controller so that, for example, the controller automatically makes suitable beam direction adjustments for a particular type of care utensil. Various embodiments are conceivable.

The proposed cleaning and disinfection device thus further reduces manufacturing and assembly costs. Furthermore, storage costs can be drastically reduced because, for example, the number of nozzles held can be reduced to a minimum for certain beam direction angular positions, preferably to a single, adjustable nozzle. As a result, it is possible to achieve considerable production advantages and logistical advantages.

FIGS. 3a and 3b

an embodiment of a two-part nozzle in different positions of the beam direction.

In the FIGS. 1 and 2 an embodiment of a washer-disinfector 110 is shown in partial cut-away view from the side. The cleaning and disinfecting device 110 has a washing chamber 112 with a front-side hinged door 114 as the washhouse door. It shows FIG. 1 the washer-disinfector 110 with the front flap door 114 open, whereas FIG. 2 shows a position in which the front flap door 114 is closed. It should be noted that other embodiments of the washing chamber 112 than those in the FIGS. 1 and 2 illustrated embodiments are possible, for example, embodiments with a different type of door, for example on an upper side of the device or similar embodiments. However, the present embodiment is particularly preferred since a vessel holder 116 can be provided on the front flap door 114, in which one or more care utensils 118, exemplified here in the form of a bedpan 120 and a urine bottle 122, can be introduced. When closing the front flap door 114, these care utensils 118 can be tilted, so that these care utensils 118 can be at least largely freed from liquid and / or solid contents by emptying. These solid and / or liquid contents can be disposed of as waste, for example, in a drain 124, which is merely indicated in the figures. The drain 124 may be provided, for example, with an odor barrier in the form of, for example, a siphon bend with a liquid barrier and connected to a corresponding drainage system.

Inside the wash chamber 112, a spray system 126 is provided, by means of which the care utensils 118 can be acted upon with at least one cleaning fluid. This spraying system 126 is configured in several parts in the present embodiment and comprises a plurality of individual nozzles 128, 130. These nozzles 128, 130 serve different purposes and are in the FIGS. 1 and 2 only symbolically indicated. While the nozzles 128 may be provided substantially for cleaning the bedpan 120 and for cleaning the exterior of the care utensils 118 and may be configured as non-adjustable nozzles, for example, the nozzle 130 serves for internal cleaning of the urine bottle 122. This nozzle 130, whereby several such nozzles 130 may be provided, is designed according to the invention as an adjustable nozzle.

The operation of the spray system 126 and the nozzles 128, 130 is in particular the illustration according to FIG. 2 which shows the cleaning and disinfecting device 110 with the front flap door 114 closed. The care utensils or cleaning goods, for example the bedpan 120 and the urine bottle 122, are fixed in this position by the vessel holder 116 such that they can be emptied and cleaned. On the nozzles 128, 130 is shown schematically in the figures, the exit of jets of cleaning fluid.

For example, while nozzles 128 may emit multiple fan-shaped jets or may otherwise cover a wider range of angles, nozzle 130 configured for interior cleaning of care utensils 118, such as urine bottle 122, emits one or more comparatively sharply focused jets 132. In the following, it is assumed that this is a single beam 132, although other embodiments are possible. In this case, the nozzle 130 discharges the jet 132 in such a way that it is emitted in a jet direction in which the jet 132 impinges on a bottom or base of the urine bottle 122 through a neck. There bursts the jet 132, so that the cleaning fluid, as in FIG. 2 represented symbolically, distributed over the entire inner surface of the urine bottle 122, this preferably wetted and thus cleans.

Furthermore, in the illustration according to FIG. 2 clearly that the jet 132 which the nozzle 130 emits for internal cleaning must preferably be comparatively narrow and must be aligned relatively precisely to the care utensils 118, for example to the urine bottle 122, so that the cleaning fluid can reach the bottom of the care utensils. If the jet 132 had previously hit the inside of the neck or side surfaces of the urine bottle 122, the cleaning fluid would not be able to penetrate to the bottom surface, with the result that portions of the interior surfaces of the urine bottle 122 would not be cleaned.

In the FIGS. 3a and 3b is an embodiment of the nozzle 130, which, for example, according to the FIGS. 1 and 2 for internal cleaning of care utensils 118 such as urine bottles 122 can be used, shown in side view. In this exemplary embodiment, the nozzle 130 comprises a nozzle block 134 which, for example, can be fixedly mounted on a wall of the washing chamber 112. At this nozzle block 134, which acts as a fixed part of the nozzle 130, a nozzle head 136 is mounted as an adjustable part. This nozzle head 136 is mounted angularly movable in the illustrated embodiment about a single pivot axis 138. Thus, an angular position of the beam 132, which in the FIGS. 3a and 3b with α ₁ or α ₂ , are adjusted. FIG. 3a shows an angle α ₁ , which is greater than the angle α ₂ shown in Figure 3b. An adjustment about a plurality of pivot axes 138 is basically possible and / or a pivot axis-free adjustment, for example by means of a ball joint or similar adjusting devices.

The nozzle head 136 is adjustable, but designed detectable. By a arranged in the interior of the nozzle block 134 bore or more such holes, which are not shown in the figures, the cleaning fluid is supplied to the nozzle head 136. In the interior of the nozzle head 136, the jet 132 is formed and delivered in a predetermined by the position of the nozzle head 136 jet direction into the washing chamber 112 and / or in the cleaning material in the form of care utensils 118. At smaller angles α ₂ such as in FIG. 3b shown, the jet 132 is delivered steeper upward and reaches it, for example, even in more kinked urine bottles 122 still the bottom of the urine bottle 122st

In the exemplary embodiment illustrated, the nozzle 130 comprises a locking means 140, by means of which the position of the jet 132 can be fixed or determined after the adjustment has taken place. This locking means 140 is in the FIGS. 3a and 3b shown symbolically in the form of a screw 142. However, other types of locking means 142 are basically possible. The change in the angular position of nozzle block 134 and nozzle head 136 is made possible by the release of the locking means 140 and the screw 142, which may be arranged for example in the pivot axis 138. After releasing the locking means 140, the nozzle head 136 can be pivoted relative to the nozzle block 134, so that a changed angle α ₁ or α ₂ results. The adjustment is facilitated by the fact that at least one latching device 144 can be provided on the nozzle block 134 and / or on the nozzle head 136. By way of example, this latching device can also comprise display means, for example in the form of markings 146, which make it possible to detect currently applied settings of the beam direction of the beam 132.

When the adjustment is made, the locking means 140 can be fixed again, for example by tightening the screw 142. Thus, the nozzle head 136 is permanently fixed so that it can not be adjusted during operation of the washer-disinfector 110.

Instead of the screw 142, other means than locking means 140 are conceivable and usable, which fulfill the purpose of fixing. For example, cotter pins, pins, union nuts or other types of fixative 140 or combinations of such fixatives and / or other types of fixative may be employed.

In order to minimize the loss of cleaning fluid in a possibly resulting gap between nozzle block 134 and nozzle head 136, a sealing device is provided between these components, for example in the form of a labyrinth seal. These may include, for example, grooves and strips. The labyrinth seal is in the FIGS. 3a and 3b not shown.

The described setting process of the beam direction of the beam 132, for example, during assembly of the washer-disinfector 110, for example, to vote on the specific requirements of a customer order made. Alternatively or additionally, however, the adjustment process can also be carried out later, for example on site at a customer, for example if the customer's requirements change during the course of an operating period.

The described nozzle 130 can basically be made in various ways. For example, the nozzle may be made of plastic and / or metal. For example, can be used to make the nozzle 130 machining process. A particularly preferred manufacturing method is the production of the individual parts by a plastic injection molding method or similar methods. Another conceivable method is the production of the nozzle parts by means of so-called e-manufacturing methods, ie methods in which a shape follows with the aid of 3D data. For example, plastic or metal powder, for example by selective laser sintering (SLS), can be brought into a desired shape.

In addition, it should also be mentioned that a washer-disinfector 110 and other types of care utensils 118 may, of course, also be equipped with a plurality of adjustable nozzles 130 described above, especially if the simultaneous use of more in use and apparatus determination as a care utensil, for example more than one urine bottle and / or other types of vessels.
