Title: Endoscope valve element holder
The invention relates to a endoscope valve element holder and method to clean an endoscope valve element.
It is importance that endoscopes are properly cleaned between subsequent uses. For 5 this reason special cleaning devices are known which are used to clean endoscopes. In such cleaning device the channels within the medical device are connected to feed lines so that each channel can be separately flushed with a cleaning and/or disinfection fluid. Such cleaning device is for instance disclosed in EP 0 709 056.
To properly clean the endoscope valve elements of the endoscope should be 10 removed before cleaning. During the cleaning process a separator element may be arranged in the valve housing as a replacement for the valve element to define distinct channels to be cleaned in the housing.
The removed valve element or valve elements are preferably kept together with the endoscope during the cleaning process so that the endoscope and valve elements can easily 15 be reassembled after cleaning of the endoscope. The known cleaning device often comprises a basket within a cleaning space of the cleaning device in which the valve elements can be held during the cleaning process.
Although this basket is flushed with cleaning fluid during the cleaning process of the endoscope, the valve element may not be properly cleaned when the cleaning process of the 20 endoscope has finished.
It is an object of the invention to provide a device and a method with which endoscope valve elements can reliably be cleaned during the cleaning process of an endcoscope, preferably together with the associated endoscope.
The invention provides an endoscope valve element holder for holding a valve 25 element of an endoscope during a cleaning process with a cleaning fluid, comprising a housing and a cap mountable on the housing, wherein the housing and the cap, when mounted on each other, define a space for holding the valve element, wherein the holder comprises an inlet for entrance of the cleaning fluid and an outlet for discharging the cleaning fluid, wherein the inlet and outlet are arranged such that one or more flow paths of the 30 cleaning fluid from the inlet to the outlet run forcibly along inner and outer surfaces of the valve element.
The endoscope valve element holder according to the invention thus defines one or more flow paths along inner and outer surfaces of the valve element. Cleaning fluid 2 introduced in the holder is forced by these one or more flow paths to flow along these inner and outer surfaces so that these surfaces of the valve element are reliably cleaned. The one or more flow paths between the inlet and outlet are substantially formed by an inner surface of the space and the inner and outer surfaces of a valve element held in the space during 5 cleaning of the valve element.
In an embodiment, the one or more flow paths together run along substantially all the inner surfaces and the outer surfaces of the valve element. By passing forcibly the one or more flow paths along subtantially all inner and outer surfaces, substantially the whole surface of the valve element will be cleaned. Some surface area will be required to hold the 10 valve element in the valve element holder. Preferably this surface area for holding the valve element is minimized for optimal cleaning of the valve element.
In an embodiment, the space is shaped such that an inner surface of the space substantially follows an outer contour of the valve element. By shaping the space such that the gap between the valve element and the housing or cap is relative small, the cross section 15 of the cleaning fluid flow through the valve element holder can also be kept low. As a result, the speed of fluid flow along the inner and outer surfaces is relative high, therewith optimizing the cleaning effect of the cleaning fluid on the valve element arranged in the valve element holder.
Preferably, for each type/embodiment of endoscope valve element a separate 20 combination of cap and housing is designed so that a space defined by the cap and housing is specially adapted for that specific type/embodiment of endoscope valve element.
In an embodiment, the endoscope valve element holder comprises a second cap mountable on the housing, wherein the housing and the second cap, when mounted on each other, define a second space for holding a second valve element.
25 Many endoscopes comprise two valve elements. It is desirable that these valve elements are kept together during the cleaning of the endoscope. In this embodiment, the valve element holder is suitable for holding two valve elements so that two valve elements of a single endoscope can be arranged in the single valve element holder. The one or more flow paths between the inlet and outlet are substantially formed by an inner surface of the 30 space and second space, and the inner and outer surfaces of valve elements held in the space and second space during cleaning of the valve elements.
Preferably, the space and second space are each specially designed for a specific type/embodiment of an endoscope valve element.
In an embodiment, the space and second space are in fluid communication, the inlet 35 is provided in the space and the outlet is provided in the second space, such that one or more flow paths of the cleaning fluid from the inlet to the outlet run forcibly along inner and outer surfaces of both the valve element and the second valve element.
3
In an embodiment, an longitudinal axis of the inlet is aligned with a longitudinal axis of a channel of a valve element held in the holder. By this arrangement the cleaning liquid is directly introduced in a hollow space of the valve element. This may have a positive influence on the cleaning effect of interior surfaces of the valve element.
5 In an embodiment, the inlet comprises multiple openings to the space as a beginning of multiple flow paths of cleaning fluid. To obtain a relative simple flow scheme within the space, it may be desirable to split the fluid flow entering the space via the inlet in a number of flows, each flow following a flow path towards the outlet. The flow paths may merge and split again towards the outlet. The start of separate flow paths may be obtained by providing an 10 inlet with two or more openings towards the space.
In an embodiment, the holder comprises a sealing element for a sealing engagement between the housing and the cap. It is of importance that during use no cleaning fluid leaks from the valve element holder. Therefore it may be desirable to arrange a sealing element between the housing and the cap so that no leakage occurs during normal use of the valve 15 element holder with a valve element arranged therein.
In an embodiment, the cap and housing are configured to be pressed in a sealing engagement by a biasing element of the endoscope valve element. Many endoscopes comprise valve elements having two components with a spring therebetween. The components may be moved in longitudinal direction with respect to each other by 20 compression of the spring. This spring force may be used to sealingly engage the cap on the housing. When the components of the valve element have to be moved with respect to each other when the cap is placed on the housing, the cap is pushed back by the springforce. By preventing the cap from completely being moved back, the spring force can be used for a sealing engagement between the cap and the housing.
25 This has the advantage that when no valve element is present in the space, there is no spring force to push the cap and the housing away from each other. As a result, leakage may occur between the cap and housing. Such leakage may be detected by the cleaning device. In this way it can be avoided that a cleaning process is performed without the presence of a valve element in the space of the valve element holder.
30 As an alternative, a spring or other biasing element can be provided between the valve element and the housing or cap to obtain a force which presses the cap and housing away from each other when a valve element is arranged in the valve element holder. The spring or biasing element may be an integral part of the housing or the cap or be provided as a separate element.
35 The provision of a bayonet locking arrangement between the cap and the housing may be very useful for this leak detection configuration.
4
In an embodiment, the inlet comprises a one-way valve and/or the outlet comprises a one-way valve. In this way it may be avoided that a cleaning process can be started when the outlet of the valve element holder is connected to a feed line. The cleaning device may detect that no flow is possible througgh the valve element holder, and stop feeding cleaning 5 fluid to the holder.
The invention also relates to a method for cleaning an endoscope valve element in a cleaning device for an endoscope, comprising the steps of: - providing the endoscope valve element holder of any of the claims 1-13, - arranging the endoscope valve element in the space of the holder and closing the space by 10 mounting the cap on the housing, - connecting the inlet to a cleaning fluid feed line of the cleaning device, and - cleaning the valve element by flushing of cleaning fluid through the holder.
In an embodiment the inlet of the valve element holder may already be connected to the cleaning fluid feed line before the valve element is arranged in the valve element holder.
15 The step of connecting the inlet to the feed line may even comprise one time permanently connecting the inlet to the feed line. This has the advantage that the valve element holder cannot be wrongly connected to the cleaning fluid feed line.
In an embodiment, the step of connecting comprises connecting the endoscope valve element holder serially with a channel of an endoscope to be cleaned. The advantage of 20 such arrangement is that the same feed line can be used for the cleaning of one or more valve elements arranged in the valve element holder, and a channel of an endoscope. In such arrangement no separate feed line has to be provided for the cleaning of the valve elements.
25 Embodiments of the invention will now be described, by way of example only, with reference to the accompanying schematic drawings in which corresponding reference symbols indicate corresponding parts, and in which:
Figure 1 shows a side view of first embodiment of a valve element holder according 30 the invention carrying a valve element;
Figure 2 shows a cross section of the embodiment of Figure 1 along the line A-A; Figure 3 shows a cross section of the embodiment of Figure 1 along the line B-B; Figure 4 shows a side view of second embodiment of a valve element holder according to the invention carrying two valve elements; 35 Figure 5 shows a cross section of the embodiment of Figure 4 along the line A-A; 5
Figure 1 shows a first embodiment of a endoscope valve element holder, generally indicated by the reference numeral 1. The endoscope valve element holder 1 comprises a housing 2 and a cap 3. The housing 2 comprises an inlet 4 to connect a cleaning fluid feed line of a cleaning device for introducing cleaning fluid into the valve element holder 1. The 5 cap 3 comprises an outlet 5 so that fluid can leave the valve element holder 1. Longitudinal axes of the inlet 4 and the outlet 5 are aligned with a longitudinal axis of the valve element holder 1.
The cap 3 is mounted on the housing 2 by a bayonet locking arrangement formed by hook-formed grooves 6 in the cap 3 and pins 7 extending radially from the housing 2. A 10 friction surface 8 is provided on the cap 3 to make manipulation of the cap 3 more easy during mounting of the cap 3 on the housing 2.
Figure 2 shows a cross section of the valve element holder 1. A valve element 20 is arranged in the space 9 defined by the housing 2 and the cap 3. The valve element comprises a first component 21 and a second component 22 which are connected to each 15 other by a spring element 23 which makes movement of the first component and the second component with respect to each other possible.
The inlet 4 and the outlet 5 are arranged such that one or more flow paths of cleaning fluid from the inlet 4 to the outlet 5 run forcibly along inner and outer surfaces of the valve element so that all these inner and outer surfaces of the valve element 20 are reliably 20 cleaned during the cleaning process. These flow paths are defined by the inner surface of the space, i.e. the inner surfaces of the cap 3 and the housing 2 defining the space 9, and the components 21, 22 of the valve element 20.
As for instance shown in Figure 2, the flow of cleaning fluid is introduced in the space 9 by inlet 4 and passes the outer contour of the first component 21. At the cross section B-B, 25 shown in Figure 3, the cleaning fluid flow is split in a flow through the openings 12 between the outer contour of component 22 and a flow between components 21 and 22. Before the outlet 5 is reached the flows paths join so that the flow continues along a single flow path throught the outlet 5.
By the shape of the space 9 and the components 21,22 of the valve element 20 two 30 flow paths through the holder 1 are created which together run along all the inner surfaces and the outer surfaces of the valve element 20. The flow of cleaning fluid only does not pass surfaces of the valve element 20 required for holding the valve element 20 in the holder 1. In this way a proper cleaning of substantially all the surfaces of the valve element 20 is obtained.
35 The three openings 12 are provided so that parts of the rim 10 can be used for supporting the valve element 20 on the housing 2. Preferably the openings 12 are as large as possible to obtain an optimal flow along the valve element 20.
6
The inner surfaces of the space 9 are shaped such that the inner surface of the space 9 substantially follows an outer contour of the valve element 20. By shaping the space 9 such that the gap between the outer contour of the valve element 20 and the respective inner surface of the housing 2 or cap 3 is relative small, the cross section of the cleaning fluid flow 5 through the valve element holder 1 can be kept low. As a result, the speed of fluid flow along the inner and outer surfaces of the valve element 20 is kept relative high, therewith optimizing the cleaning effect of the cleaning fluid on the valve element 20 arranged in the holder 1.
During mounting of the cap 3 on the housing 2, the outlet 5 pushes the first 10 component 21 towards the inlet 4 resulting in the spring 23 being compressed. As a result, the first component 21 exerts a reaction force on the outlet 5, while the second component is supported on the rim 10 of the housing 2. As a result, the housing 2 and the cap 3 are pushed away from each other, resulting in a proper sealing between the housing 2 and the cap 3 at the sealing ring 11.
15 This sealing may not obtained when no valve element 20 is present in the space 9, since in that case the housing 2 and cap 3 will not be pushed away from each other. This may result in leakage between the housing 2 and the cap 3 when no valve element 20 is present. Such leakage may be detected by the cleaning device, and starting a cleaning process without a valve element properly placed in the holder 1 may be prevented.
20 Figures 4 and 5 show a second embodiment according to the invention. Same parts or parts having the same function are indicated by the same reference numerals. The endoscope valve element holder 1 of Figures 4 and 5 comprises a second cap 15 which can be mounted on the other side of the housing 2. The second cap 15 defines together with the housing a second space 16 wherein a second valve element 30 can be arranged. The 25 second valve element 30 also comprises two components 31, 32 which are connected to each other by a spring element 33.
The second cap 2 is mounted and locked in the same way on the housing 3 so that the absence of the valve element 30 may be detected by the cleaning device during the cleaning process since leakage will occur.
30 The space 9 and the second space 16 are in fluid communication. The inlet 4 is provided in the second space 16 and the outlet is provided in the space 9 so that cleaning liquid introduced in the valve element holder 1 will run through the space 9 and the second space 12. The design of the valve holder 1 is such that multiple flow paths of cleaning fluid from the inlet 4 to the outlet 5 run forcibly along inner and outer surfaces of the valve element 35 20 and 30 so that all these inner and outer surfaces of the valve elements 20, 30 are reliably cleaned during the cleaning process. These flow paths are defined by the inner surface of 7 the space, i.e. the inner surfaces of the caps 3,15 and the housing 2 defining the spaces 9, 16, and the components 21,22, 31,33 of the valve elements 20, 30.
A longitudinal axis of the inlet 4 is aligned with a longitudinal axis of a channel 34 of the valve element 30. The inlet 4 comprises one opening 17 directly connecting to this 5 channel 34 so that part of cleaning fluid entering te holder 1 is introduced via a first flow path in the channel 34. At the end of the channel 34 the fluid will leave the interior of the valve element 30.
The inlet 4 comprises further openings 18 to the second space 16 as a beginning of another flow path of cleaning fluid through the holder 1. This second flow path is split in flow 10 a path running between components 31 and 32 and a flow path running around the component 32 via openings 12, similar to the openings 12 shown in Figure 3. The flow paths will join each other at the end of the second space 16 remote from the inlet to run into the space 9 where the flow paths will continue as described with respect to Figures 1,2 and 3. It is clear that the flow paths run along substantially all the inner and outer surfaces of the valve 15 element 30. Therewith a proper cleaning of all these surfaces is obtained.
Correspondingly to space 9, the inner surfaces of the second space 16 are shaped such that an inner surface of this space second 16 substantially follows an outer contour of the valve element 30. As a result, the cross section of the cleaning fluid flow through the valve element holder 1 can also be kept low in the second space 16, and the speed of fluid 20 flow along the inner and outer surfaces of the valve element 30 can be kept relative highto optimize the cleaning effect.
It may be desirable that the fluid flow through the holder can only take place in one direction. In such case a one-way valve may be arranged in the inlet 4 or the outlet 5. Such one-way valve may also be provided in the feed line for cleaning fluid.
25 During use, the endoscope valve element holder 1, may be connected to a separate cleaning fluid feed line, or serially with a channel of an endoscope to be cleaned. The latter has the advantage that no separate feed line has to be provided and validated. Also no separate or new cleaning device has to be provided when all feed lines are alresdy used for cleaning of an endoscope.
30 The valve element holder may permanently be connected to the feed line so that the feed line only can be used when the cap 3 is mounted on the housing 2, while a valve element 20, 30 is arranged in the respective space 9, 16.
Hereinabove, the term cleaning or to clean is used to describe an action for preparing a hollow medical device, in particular endoscope for subsquent use. This action may 35 comprise disinfection or sterilization of the medical device. Correspondingly, the term cleaning fluid may relate to a cleaning agent, desinfection agent, or fluid for sterilization of the medical device.
