Abstract

A system for supplying process medium to a medical article having multiple channels is disclosed. The system includes a medical processing device including multiple nozzles. The system also includes a detachable coupling device including multiple fluid passageways configured to be connectable to each of the channels of the medical article before the detachable coupling device is inserted into the medical processing device. The detachable coupling device is configured to be positioned at a docking location within the medical processing device such that movement of the nozzles from a retracted position to an advanced position causes the nozzles to engage with each of the fluid passageways of the detachable coupling device, thereby enabling the medical processing device to supply process medium from the nozzles through the engaged fluid passageways of the detachable coupling device into any of the channels of the medical article connected to the detachable coupling device.

Description

[Technical Field]

[0001] SUMMARY The present disclosure relates to a system for delivering a process medium to a medical article having multiple channels for cleaning, disinfecting, and drying the channels. [Background technology]

[0002] Medical articles having multiple channels are frequently used in hospitals, such as in surgical departments and similar facilities. The channels can be used to provide access to body organs without any surgical intervention or with only limited surgical intervention. For example, different types of endoscopes are examples of such medical articles.

[0003] Such medical articles should be cleaned / disinfected after use so that they can be reused at another time. Cleaning and / or disinfection can be performed, for example, in a combined medical washer-disinfector typically provided in surgical departments, central sterile supply departments, and similar facilities. The medical washer-disinfector is configured to allow medical articles to be cleaned not only externally but also internally, i.e., inside the channels. To clean and / or disinfect the channels, each individual channel is manually connected to a respective connector in the medical washer-disinfector. Water, disinfectant chemicals, and / or detergents can then be supplied to each channel through the connector. After treatment of the medical articles is complete, the channels are manually disconnected. Typically, the medical articles are then transferred to a drying cabinet to dry the medical articles both externally and internally. Again, each channel is manually connected to a connector on the drying cabinet, this time allowing air to circulate through the channel to dry it. Finally, the channels are manually disconnected from the connector on the drying cabinet. Repeated manual connection and disconnection is time consuming. Summary of the Invention [Problem to be solved by the invention]

[0004] It is an object of the present disclosure to alleviate the above-mentioned drawbacks of conventional washer-disinfectors. This and other objects, which will become apparent hereinafter, are achieved by a system as defined in claim 1. Some non-limiting exemplary embodiments are set out in the dependent claims. [Means for solving the problem]

[0005] Applicant has determined that the channels of the medical article should be connected to a detachable coupling device that can serve as an interface between the channels and a medical processing device (e.g., a washer-disinfector or a drying cabinet, etc.). Applicant has also determined that the actual act of connecting the channels to the detachable coupling device can be performed outside the medical processing device; then, when the detachable coupling device (now with the channels connected) is inserted into the medical processing device, the nozzle of the medical processing device can be moved into the detachable coupling device to quickly form a tight seal, allowing process media to be passed from the nozzle through the intermediate detachable coupling device and into the channels. Advantageously, there is no need to disconnect the channels when the medical article is to be moved from one medical processing device to another, for example, from a washer-disinfector to a drying cabinet. Instead, the detachable coupling device can be simply moved from one medical processing device to another with the channels still connected. By providing a movable nozzle such that the nozzle can be engaged with a detachable coupling device and then moved back out of the way when not in use, smooth loading and unloading of medical articles can be achieved without damaging the nozzle, catching objects on the nozzle, or risking operator injury from a protruding nozzle.

[0006] Thus, in accordance with at least a first aspect of the inventive concept, there is provided a system for supplying a process medium to a medical article having a plurality of channels, the system comprising: - a medical processing device configured to receive a medical article exposed to a process medium, the medical processing device including a plurality of nozzles, each nozzle being movable between a retracted position and an advanced position; - a detachable coupling device including a plurality of fluid passageways, each fluid passageway configured to be connectable to a respective channel of a medical article having multiple channels before the detachable coupling device is inserted into the medical processing device; and Including, A system is provided in which the detachable coupling device is configured to be positioned at a docking location within the medical processing device, such that movement of the nozzles from the retracted position to the advanced position causes at least some of the nozzles, and in particular all of the nozzles, to become engaged with respective fluid passages of the detachable coupling device, thereby enabling the medical processing device to supply process medium from the nozzles through the engaged fluid passages of the detachable coupling device and into any channels of the medical article connected to the detachable coupling device.

[0007] The medical processing device can be used to clean and / or disinfect medical articles. It should be understood that in this disclosure, the terms "washing" and "cleaning" are considered interchangeable and that the system is for both.

[0008] By providing a detachable coupling device and configuring the nozzle of the medical processing device to be advanceable to engage the detachable coupling device, a time-saving, robust system is achieved. As previously shown, by allowing the nozzle to be moved to an advanced position for processing a medical article and then returned to a retracted position (preferably retracted into a wall or side surface of the device chamber), efficient docking of the detachable coupling device is achieved without compromising the integrity of the nozzle. By having a movable nozzle, it is possible to store the nozzle (in the retracted position) in a manner that protects it from accidental collision with other components, such as during loading and unloading of medical articles in the medical processing device. Notably, multiple nozzles may be advanceable separately from structures and surfaces surrounding and between the multiple nozzles.

[0009] In some preferred embodiments of the retracted position, the nozzles are withdrawn such that they are behind the plane of the chamber surface immediately surrounding the nozzles, and / or the nozzles are withdrawn completely from within the device chamber.

[0010] As indicated above, the detachable coupling device may be suitably used in connection with a variety of different types of medical processing devices. For example, in the present disclosure, a medical processing device may be a washer, disinfector, combination washer-disinfector, dedicated endoscope reprocessor or endoscope washer-disinfector, drying cabinet, combination drying and storage cabinet, etc. Moreover, while the system may be used to deliver process medium to any suitable medical article having multiple channels, it is envisioned that the system may be used, among other things, to deliver process medium to endoscopes having multiple channels. Nevertheless, while the beneficial time savings discussed in this disclosure relate, among other things, to medical articles having multiple channels, it should be understood that the system of the present disclosure may also be used to deliver process medium to medical articles having a single internal channel. Thus, it should be understood that any fluid passageway of the detachable coupling device that is not connected to a respective internal channel of the medical article can be used, for example, to flush process medium outside the medical article and / or can be partially restricted to reduce flow through that fluid passageway without causing undesired pressure effects in the system (assuming all nozzles are engaged with their respective fluid passageways and all nozzles supply process medium).

[0011] In some examples, the movement of the nozzles may be individually controllable and / or the supply of process medium from the nozzles may be individually controllable, while in other examples, the nozzles may be suitably configured to be moved collectively, since this simplifies overall control of the nozzle movement. Moreover, all of the nozzles may be suitably collectively provided with process medium from a common process medium source. For example, all of the nozzles (and corresponding connected lumens) may first be simultaneously provided with one or more liquids for cleaning and / or disinfection, and then simultaneously provided with a gas (e.g., air) to dry the lumens. Optionally, there may be an alcohol step between the first liquid step and the gas step. In such an embodiment, there is no need for individually controllable valves to be provided between the process medium source and the nozzles.

[0012] Depending on the medical treatment device, different types of process medium can be supplied. The process medium can be any suitable type of fluid. Examples of such fluids are liquids and gases. The liquid can be, for example, water (with or without detergent or disinfectant), alcohol, or any other suitable liquid. The gas can be, for example, air. Thus, if the medical treatment device is in the form of a washer-disinfector, a liquid can be suitably used as the process medium, while in the case of a drying cabinet, the process medium can suitably be air.

[0013] An interior channel of a medical article may sometimes be referred to as a lumen. Without being bound to any particular terminology with respect to the inventive concepts, it should be understood that both channel / lumen can refer to a passageway within a medical article, such as the interior of an endoscope.

[0014] According to at least some exemplary embodiments, the medical processing device includes a docking unit, the docking unit including a plurality of compartments, one for each nozzle; - in said retracted position, each nozzle is at least partially positioned within its respective compartment, in particular completely positioned within its respective compartment; In said forward position, each nozzle projects from its respective compartment. By providing each nozzle movable into and out of its respective compartment separate from the docking unit, the nozzles are well protected and discreet when not in use. Moreover, providing individual compartments facilitates optional sealing around each nozzle to prevent process media from reaching any sensitive components of the medical processing device. Examples of sealing means will be discussed later in this disclosure.

[0015] According to at least one exemplary embodiment, when moving to the advanced position, the nozzles are each advanced along a different respective central axis away from a sidewall or docking unit of the medical processing device, for example, the nozzles can each be advanced away from the docking unit described above.

[0016] According to at least one exemplary embodiment, in the retracted position, the nozzles are at least partially within respective cavities of the medical processing device, and in the advanced position, the nozzles extend into respective cavities of the detachable coupling device. If a docking unit is included in the medical processing device, the cavities of the medical processing device can correspond to the above-mentioned compartments of the docking unit, and each nozzle can be at least partially within a respective compartment of the docking unit in the retracted position. The respective cavities of the detachable coupling device can suitably form a portion of a respective one of the fluid passageways of the detachable coupling device.

[0017] According to at least some exemplary embodiments, the docking location for the detachable coupling device is aligned with the docking unit such that, when the detachable coupling device is positioned at the docking location, the respective fluid passages are coaxially aligned with the respective nozzles. The docking location may be suitably defined by a holder, a receiving element, a bracket, an end stop, or any other suitable means that allows the docking location to be easily positioned when inserting the detachable coupling device into the medical processing device. However, it should be understood that positioning the detachable coupling device at the docking location need not necessarily be facilitated by elements or features within the medical processing device and, in some instances, can be facilitated by other elements (even external elements). For example, rather than placing medical articles directly on the floor of the internal chamber of the medical processing device, it is common practice to place the medical articles in a load carrier (e.g., a basket or tray), which is then inserted into the chamber of the medical processing device. Such a load carrier can be introduced into the chamber of the medical processing device, for example, by sliding it along rails within the chamber. Thus, in at least some exemplary embodiments, the system can include a load carrier having a predefined receiving portion to which a detachable coupling device is to be attached, and when the load carrier is subsequently fully introduced into the chamber of the medical processing device (with the detachable coupling device attached to the predefined receiving portion), the detachable coupling device can thereby automatically arrive at a docking location within the medical processing device.

[0018] According to at least some exemplary embodiments, in the nozzle's advanced position, the nozzle is configured to protrude into the fluid passage of the detachable coupling device. Technical advantages may include that the detachable coupling device may be relatively simple in design, including that a plurality of through-holes form the fluid passage, and in some embodiments, that it has no actively moving parts, or at least no parts that are required to move during the docking process. Thus, the nozzle-receiving side of the detachable coupling device may be substantially flat, with the fluid passage extending from the flat side through the detachable coupling device to the opposite side. In this case, the nozzle may be considered a male connector, and the detachable coupling device (with its fluid passage) may be considered to form a female connector. While the above-described configuration is advantageous, it should be understood that the general inventive concept may also be implemented by configuring the nozzle as a female connector, which, when advanced, engages and surrounds the respective male connector that forms the fluid passage of the detachable coupling device.

[0019] According to at least one exemplary embodiment, each nozzle is provided with at least one seal configured to follow the movement of the nozzle. By having a seal around each nozzle, the risk of fluid passing through the nozzle and leaking back around the nozzle is reduced. Furthermore, control of fluid flow rate and pressure can be more precise. If the nozzle is in the form of a male connector, the seal is advantageously provided annularly around the enveloping surface of the nozzle. If the nozzle is in the form of a female connector, the seal can instead be provided along the inner circumference of the nozzle.

[0020] According to at least one exemplary embodiment, each nozzle includes a front seal and a rear seal, each having an inner periphery in contact with and surrounding the nozzle, such that when the nozzle is in the advanced position and engaged with a fluid passageway, the outer periphery of the front seal seals against a circumferential wall portion of the engaged fluid passageway, and the outer periphery of the rear seal seals against a circumferential wall portion of the compartment from which the nozzle protrudes. In this manner, fluid flow and pressure control through the fluid passageway is precise due to the front seal, and the rear seal reduces the risk of fluid leaking into any sensitive areas of the medical processing device.

[0021] From an efficiency standpoint, it can be advantageous for a central sterile supply department or similar facility to have multiple detachable coupling devices. For example, while staff are preparing a first medical article by connecting it to a first detachable coupling device, a second medical article connected to a second detachable coupling device can already be present and undergoing treatment within a medical processing device (e.g., a washer-disinfector). At the same time, a third detachable coupling device with a third medical article connected thereto can be simultaneously transported from that medical processing device to another medical processing device (e.g., from a washer-disinfector to a drying cabinet). A fourth detachable coupling device with a fourth medical article connected thereto can simultaneously be within another medical processing device, and so on. Thus, it should be understood that, according to at least some exemplary embodiments, a system can include multiple detachable coupling devices. It is contemplated that one or more detachable coupling devices of the system can be provided with a sealing element. However, considering the above example where a system may have more detachable coupling devices than medical processing devices, it may be more convenient and cost effective to provide a seal on the nozzle of the medical processing device rather than equipping each one of the multiple detachable coupling devices with a sealing element.

[0022] According to at least one exemplary embodiment, in the nozzle's advanced position, when the nozzle engages the fluid passage, the nozzle prevents the detachable coupling device from moving radially relative to the axial extension of any one of the nozzles. This is advantageous because a separate locking step or mechanism is not required for movement in said dimension. Regarding preventing movement of the detachable coupling device in the axial direction (i.e., along the axial extension of any one of the nozzles), there may be various ways to achieve this. For example, the detachable coupling device may be securely attached to a load carrier (e.g., a tray or basket, etc.), which itself is prevented from moving in its axial dimension by a chamber wall or in other ways. Such secure attachment may also resist radial movement. Additional locking against axial and / or rotational movement can be achieved by appropriately designing the docking unit described previously. The docking unit may have a locking feature that engages the detachable coupling device when it reaches its docking location.

[0023] Similar to the above example, according to at least one exemplary embodiment, the detachable coupling device includes or is a part of a structure for holding a medical article when the medical article is connected to the detachable coupling device, including, among other things, a basket, bin, box, tray, or platform. Thus, it should be understood that the present disclosure can encompass a structure to which the detachable coupling device can be attached prior to and detached after medical article treatment, and that the present disclosure encompasses an integrated structure for holding a medical article.

[0024] According to at least one exemplary embodiment, the medical processing device includes an actuator configured to move the nozzle between said retracted position and said advanced position, which is advantageous as the movement of the nozzle may be suitably motorized and / or automated.

[0025] According to at least one exemplary embodiment, the actuator includes a motor and a movable actuator part, the motor configured to drive the movable actuator part in alternating forward and reverse motions along a first geometric axis; one of the forward and reverse movements of the movable actuator part causes the nozzle to move transversely to the first geometric axis from a retracted position to an advanced position; The other of the forward and reverse movements of the movable actuator part causes the nozzle to return from the extended position to the retracted position. By configuring the movable actuator part to travel in one direction and the nozzle to travel in another direction, a space-saving arrangement can be achieved. For example, the movable actuator part can travel vertically upward and downward along the vertical walls of the medical processing device, while the nozzle can be advanced and retracted horizontally to engage / disengage with a fluid passage of a detachable coupling device positioned within a chamber of the medical processing device. Thus, in a general sense, a motor can drive the movable actuator in one direction, which can be transmitted to vertical movement of the nozzle.

[0026] According to at least one exemplary embodiment, the actuator part includes an inclined plane configured to interact with the nozzle-holding part, such that movement of the actuator part in one of the forward and reverse motions causes the inclined plane to push the nozzle-holding part transversely to the first geometric axis, thereby moving the nozzle from a retracted position to an advanced position. By using an inclined plane to transmit the motion of the actuator part, it is possible to create an overall space-saving configuration of the actuator. For example, the actuator part can be moved along the vertical extension of the medical processing device without requiring any additional vertical space, and the inclined plane can effectively transmit the vertical motion to the horizontal motion of the nozzle-holding part without requiring excessive horizontal space.

[0027] According to at least one exemplary embodiment, the system further includes a control unit configured to send a motion request to the actuator to cause the actuator to move the nozzle between the retracted position and the advanced position. The control unit can receive an input signal, and based on the input signal, it can send the motion request to the actuator. In some examples, the input signal can be received from a user interface. The user interface can be, for example, a control panel on the medical processing device and / or a remotely located input device (e.g., a remote computer or telephone). For example, a staff member can send an input signal from the user interface to the control unit after confirming that the detachable coupling device is positioned at a docking location, and the control unit will then send a motion request to the actuator to move the nozzle to its advanced position. In some examples, the input signal can be automatically generated by the control unit. For example, means can be provided for detecting that the detachable coupling device is positioned at the docking location, which can automatically trigger an input signal to the control unit. However, the control unit may wait for a further input signal (eg, an input signal confirming that the door to the chamber of the medical processing device has been closed) before sending the movement request.

[0028] The control unit may include a microprocessor, microcontroller, programmable digital signal processor, or another programmable device. The control unit may also (or instead) include an application specific integrated circuit, a programmable gate array or programmable array logic, a programmable logic device, or a digital signal processor. If it includes a programmable device (such as the microprocessor, microcontroller, or programmable digital signal processor described above), the processor may further include computer-executable code for controlling the operation of the programmable device. The control unit is preferably configured for use with a medical processing device and is provided with electronic instructions for implementing and controlling the advancement and retraction of the nozzle.

[0029] As mentioned above, means for detecting the position of the detachable coupling device can be provided. Thus, in a general sense, according to at least one exemplary embodiment, the system further includes a position detection device configured to indicate that the detachable coupling device is positioned at the docking location. In line with the previous description, such a position detection device can, at least in some examples, be in operative communication with the control unit. Thus, the position detection device can, for example, send an input signal to the control unit, thereby confirming to the control unit that the detachable coupling device is properly positioned to receive the nozzle. However, in other examples, the position detection device can additionally or alternatively provide information about the position of the detachable coupling device to a user interface. Such information can be conveyed in any suitable manner, such as visually (e.g., by activating a light or presenting a message on a screen) and / or audibly (e.g., by sounding an audible tone or voice message).

[0030] Any suitable position detection device can be implemented in the system of the present disclosure. For example, the position detection device can be magnet-based. A first magnet on the detachable coupling device can interact with a magnet in the medical processing device (e.g., in a docking unit), and a signal is triggered (e.g., by a switch) when the magnets are aligned. Another possibility is to configure the position detection device to be based on mechanical interaction; for example, when the detachable coupling device arrives at a docking location, it mechanically engages a switch, which triggers a signal (e.g., an input signal to a control unit or a signal to a user interface). Yet another possibility is to have a position detection device that includes an optical sensor, which visually detects the presence of the detachable coupling device.

[0031] From the above discussion, it can be appreciated that, according to at least one exemplary embodiment, a system can include a position detection device in communication with a control unit, the position detection device configured to detect that a detachable coupling device is positioned at the docking location, and upon receiving from the position detection device that the detachable coupling device is positioned at the docking location, the control unit configured to send a movement request to an actuator causing a nozzle to be moved from a retracted position to an extended position to engage a fluid passageway of the detachable coupling device. Thus, the engagement process can be advantageously automated.

[0032] According to at least one exemplary embodiment, each fluid passage has an inlet side for receiving a respective nozzle and an outlet side for connecting to a channel of the medical article, and in particular, the inlet side of each fluid passage includes a cavity for receiving a respective nozzle. Thus, the detachable coupling device can be made relatively compact, with one side facing the nozzle and the opposite side facing toward the center of the chamber of the medical processing device. The fluid passages can suitably be straight through passages, at least a portion of which is formed as a nozzle-receiving cavity. Thus, it should be understood that the cross-section of the fluid passage can vary from the inlet side to the outlet side.

[0033] According to at least one exemplary embodiment, the detachable coupling device includes a plurality of connecting nipples that define an outlet side of a flow passage, the connecting nipples configured to connect to the channels of the medical article either directly or via connecting tubing that interconnects the channels with the connecting nipples. The connecting nipples can suitably be of standard dimensions to fit existing connecting tubing and / or channels. Thus, the connecting nipples can suitably have dimensions that correspond to the dimensions of connectors in existing medical processing devices (e.g., washer-disinfectors, etc.).

[0034] As already mentioned above, in at least some exemplary embodiments, the detachable coupling device can be configured to be detachably attachable to a load carrier for carrying medical articles, such that insertion of the load carrier into the medical processing device causes the attached detachable coupling device to be positioned at the docking location. By having a predefined attachment position on the load carrier, the fluid passage of the detachable coupling device can be automatically properly aligned with the nozzle when the load carrier is inserted into the medical processing device. The load carrier can suitably be adapted to the dimensions of the chamber of the medical processing device so that it is always inserted in the same position. For example, the outer dimensions of the load carrier can suitably substantially correspond to the inner dimensions of the chamber (including any appropriate play). According to at least some exemplary embodiments, the system can include one or more load carriers configured to receive the detachable coupling device.

[0035] According to at least one exemplary embodiment, the detachable coupling device is configured to be at least partially movable when mounted on the load carrier, and each nozzle is provided with a tapered tip portion to enable automatic fine adjustment of the position of the detachable coupling device by allowing the tip portion of the nozzle to enter the fluid passage even if the nozzle and the fluid passage are not perfectly coaxially aligned when the nozzle is moved from the retracted position. Thus, the detachable coupling device can advantageously be “free-floating” or have at least a small degree of freedom to move when mounted on the load carrier. This configuration enables self-centering docking of the detachable coupling device. The detachable coupling device may be freely movable on the load carrier, within certain limits. The tapered tip portion of the nozzle (e.g., a cone-shaped tip portion) enables the detachable coupling device to be automatically properly aligned when docked by moving the nozzle from the retracted position to the extended position. This allows for proper alignment and sealing between the nozzle and the detachable coupling device (with its fluid passages).

[0036] From the above discussion and the various examples provided, it should be understood that in at least some exemplary embodiments, the detachable coupling device is configured for connection to an endoscope and the medical processing device includes one of an endoscope washer-disinfector or an endoscope drying device.

[0037] According to at least one exemplary embodiment, the medical processing device is a first medical processing device (e.g., an endoscope washer-disinfector (EWD), etc.), and the system further includes a second medical processing device (e.g., a drying and storage cabinet (DSC), etc.), the second medical processing device configured to receive a medical article exposed to the process medium; the second medical processing device includes a plurality of nozzles, each nozzle movable between a retracted position and an advanced position; The system further includes a transport arrangement; When the control unit determines that the first medical processing device has completed processing the medical article, the control unit is configured to control the transport arrangement to transfer the detachable coupling device and the medical article connected thereto from the first medical processing device into a second medical processing device, allowing a nozzle of the second medical processing device to engage with the fluid passageway of the detachable coupling device for further processing of the medical article in the second medical processing device. This is advantageous because the medical article can remain connected to the detachable coupling device throughout all process steps, even when moved from one medical processing device to another. This configuration saves time because it is not necessary to disconnect and reconnect all channels of the medical article.

[0038] In accordance with at least a second aspect of the inventive concept, there is provided a method for treating a medical article having a plurality of channels, the method comprising: - providing a detachable coupling device including a plurality of fluid passageways; - connecting each channel of the medical article to a respective fluid passage; - inserting the detachable coupling device with the connected medical article into a medical processing device, the medical processing device being configured to receive the medical article exposed to a process medium; - moving a plurality of nozzles of a medical processing device from a retracted position to an advanced position, wherein at least some of the nozzles, and in particular all of the nozzles, are engaged with respective fluid passages of a detachable coupling device, whereby the medical processing device supplies process medium from the nozzles, through the engaged fluid passages of the detachable coupling device, and into any channels of a medical article connected to the detachable coupling device; A method is provided, comprising: According to at least one exemplary embodiment of the method, the medical processing device is a first medical processing device (e.g., an endoscope washer-disinfector (EWD), etc.), and the method includes: - upon determining that the first medical processing device has completed processing the medical article, transferring the detachable coupling device and the medical article connected thereto from the first medical processing device into a second medical processing device (e.g., a drying and storage cabinet (DSC) or the like); - moving nozzles of a second medical processing device from a retracted position to an advanced position, wherein at least some of the nozzles of the second medical processing device, in particular all of the nozzles, are adapted to engage with respective fluid passages of the detachable coupling device, thereby enabling the second medical processing device to supply process medium from its nozzles through the engaged fluid passages of the detachable coupling device and into any channels of the medical article connected to the detachable coupling device; Further includes:

[0039] The reader will understand that the various features and exemplary embodiments discussed in connection with the system of the first aspect may be readily implemented as corresponding exemplary embodiments of the method of the second aspect.

[0040] In general, all terms used in the claims are to be interpreted according to their ordinary meaning in the art unless expressly defined otherwise herein. All references to "a / an / the element, apparatus, component, means, step, etc." are to be openly interpreted as referring to at least one instance of the element, apparatus, component, means, step, etc., unless expressly stated otherwise.

[0042] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which certain aspects of the disclosed system are shown. The system may, however, be embodied in many different forms and should not be construed as limited to the embodiments and aspects set forth herein. Rather, the embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the scope of the system to those skilled in the art. Therefore, it should be understood that the present disclosure is not limited to the embodiments described herein and illustrated in the drawings; rather, those skilled in the art will recognize that many changes and modifications may be made within the scope of the appended claims. Like reference numerals refer to like elements throughout the description.

[0043] 1 illustrates a system 1 for supplying a process medium to a medical article having multiple channels, in accordance with at least one exemplary embodiment of the present disclosure. System 1 includes a medical processing device 2 and a detachable coupling device 4. Medical processing device 2 is configured to receive a medical article that is exposed to the process medium. Medical processing device 2 includes an internal chamber 6, and the medical article is positioned within internal chamber 6 when exposed to the process medium.

[0044] As shown in FIG. 1 , a load carrier 8 can be provided for holding one or more medical articles. When the medical articles are held within the load carrier 8, the load carrier 8 can be inserted into the internal chamber 6 for processing of the medical articles. The load carrier 8 is shown here in the form of a basket. However, it should be understood that a basket is merely one example of a load carrier (i.e., a structure for holding medical articles). Some other examples of such structures or load carriers that can be used in connection with the system 1 of the present disclosure are bins, boxes, trays, or platforms.

[0045] As shown in FIG. 1, the inner sidewall 10 (which partially defines the internal chamber 6 of the medical processing device 2) can be provided with a plurality of rollers 12 or different structures for guiding the load carrier 8 during entry into the internal chamber 6.

[0046] The medical processing device 2 can be, for example, a washer-disinfector or drying device, particularly an endoscope washer-disinfector or endoscope drying device. Thus, the medical processing device 2 can be used for cleaning and / or disinfection, or for drying medical articles. The medical processing device 2 includes a plurality of nozzles 14, each movable between a retracted position and an advanced position (this will be discussed in more detail with respect to FIGS. 5 and 6). In FIG. 1, the nozzles 14 are illustrated as being provided within a docking unit 16 attached to the inner sidewall 10. However, in other exemplary embodiments, the movable nozzles 14 can be provided within other structures, for example, within the actual sidewall 10, without any particular docking unit 16 being present or visible. For example, the outer surface of the docking unit 16 can instead be flush with the inner sidewall 10 of the processing chamber.

[0047] Turning now to FIG. 2 , the detachable connecting device 4 includes a plurality of fluid passageways 18. In this example, a portion of each fluid passageway 18 is defined by a respective connecting nipple 20 protruding from a support portion 22 of the detachable connecting device 4. Each fluid passageway 18 may suitably extend from an end of the nipple 20, through the support portion 22, and to an opposite side of the support portion 22. The connecting nipples 20 may define outlet sides of the flow passageways 18, while the ends of the flow passageways 18 opposite the support portion 22 may define inlet sides of the flow passageways 18. The inlet sides of the flow passageways 18 are configured to engage with the nozzles 14 previously presented in FIG. 1 . In FIG. 2 , only the outlet sides of each flow passageway 18 are visible, while the inlet sides are hidden in this view. The connecting nipples 20 may be configured to connect to channels of a medical article either directly or via connecting tubing that interconnects the channels with the connecting nipples 20. The latter option is illustrated in Figure 3, which shows three connection tubes 24 connected to respective connection nipples 20. It should be understood that the connection nipples 20 are merely one possible example for connecting the detachable coupling device 4 to the channels of the medical article. In other examples, the connection can be achieved in a different manner. For example, in some examples, the support portion 22 can have different thicknesses and present integrated recesses for receiving the channels and / or connection tubes 24.

[0048] 2 and 3 show slits 26 extending from the lower end of the detachable coupling device 4 (specifically, from the lower end of the support portion 22 of the detachable coupling device 4). This allows for easy attachment of the detachable coupling device 4 onto a load carrier (such as the basket shown in FIG. 1). However, other attachment features may be used instead of or in addition to the slits 26. For example, the detachable coupling device 4 may be attached by one or more clamps, by a screw joint, by a magnet, or the like in some examples. In any one of these examples, attachment may be suitably performed in a detachable manner.

[0049] Thus, from the above, it should be understood that the detachable coupling device 4 can be removed not only from the medical processing device 2, but also from the load carrier 8. However, in some exemplary embodiments, the detachable coupling device 4 can be integrated with the load carrier 8, but still detachable from the medical processing device 2 to allow convenient connection to a medical article channel outside of the medical processing device 2. Thus, in a general sense, the detachable coupling device 4 can include or be part of a structure for holding a medical article when the medical article is connected to the detachable coupling device 4. Regardless of the particular configuration of the detachable coupling device 4, i.e., whether detachable from the load carrier 8 or not, the detachable coupling device 4 is appropriately configured for connection to an endoscope, and the medical processing device 2 can include one of an endoscope washer-disinfector or an endoscope drying device.

[0050] The detachable coupling device 4 is configured to be provided in a docking location within the medical processing device 2 such that movement of the nozzles 14 from a retracted position to an advanced position causes at least some of the nozzles 14 (in particular all of the nozzles 14) to be engaged with the respective fluid passages 18 of the detachable coupling device 4. Such a position of the detachable coupling device 4 is illustrated in FIG. 4 , which thus shows the detachable coupling device 4 positioned in its docking location. Thus, in this state, the detachable coupling device 4 is inserted into the internal chamber 6 of the medical processing device 2 (the internal chamber 6 in FIG. 1 is not shown in FIG. 4 ). As can be seen in FIG. 4 , the docking location is aligned with the docking unit 16 such that the respective fluid passages are coaxially aligned with the respective nozzles when the detachable coupling device 4 is positioned in the docking location.

[0051] 4 illustrates a medical article 28 having multiple channels. In this example, the medical article 28 is illustrated as an endoscope. The connecting tubes 24 extend from the detachable connecting device 4 to each of the channels in the medical article 28, thereby allowing each of the three connected channels in the medical article 28 to be flushed. In particular, when the nozzles engage the fluid passages in the detachable connecting device 4, the medical processing device can supply process medium from the nozzles, through the engaged fluid passages in the detachable connecting device 4, and into the channels of the medical article 28 connected to the detachable connecting device 4.

[0052] Figure 4 illustrates that the docking unit 16 is mounted to a bracket 44. An actuator (not visible in Figure 4) may be provided on the opposite side of the bracket 44, the actuator being configured to move the nozzle between the retracted and extended positions. Examples of such actuators will be discussed below in connection with Figure 7.

[0053] Movement of the nozzle 14 will now be discussed in more detail with respect to Figures 5 and 6, which are exemplary illustrations of the retracted and advanced positions of the nozzle 14 of a medical processing device, respectively, and of how the nozzle 14 engages with the fluid passage 18 of the detachable connecting device 4.

[0054] 5, a partial cross-sectional side view illustrates the detachable coupling device 4 reaching its docking location. In this position, the fluid passageways 18 of the detachable coupling device 4 are aligned with, but not yet engaged with, the nozzles 14 of the medical processing device. More specifically, now that the detachable coupling device 4 is positioned at the docking location, each fluid passageway 18 is coaxially aligned with its respective nozzle 14.

[0055] Regardless of whether the nozzles 14 are provided in a docking unit or in a sidewall of a medical processing device, there may suitably be multiple compartments 30 for accommodating the nozzles 14. A docking unit 16 having an outer surface that is flush with or continuous with an adjacent wall surface is still considered to be a docking unit 16 herein. Figure 5, for example, may illustrate a docking unit 16 that includes multiple compartments 30, one for each nozzle 14. In the retracted position shown in Figure 5, each nozzle 14 is at least partially positioned within its respective compartment 30, and more particularly, is completely positioned within its respective compartment 30.

[0056] In the detachable coupling device 4, each fluid passageway has an inlet side 32 for receiving a respective nozzle 14 and an outlet side 34 for connecting to a channel in a medical article. As shown in FIG. 5, the inlet side 32 of each fluid passageway 18 can include a cavity 36 for receiving a respective nozzle 14. As discussed above, the outlet side 34 of each fluid passageway 18 can be defined by a respective connecting nipple 20.

[0057] As mentioned previously, there can be a variety of mounting features for mounting the detachable coupling device 4 to a basket or any other suitable type of load carrier. Figure 5 illustrates that in addition to the slits 26, threaded holes 38 can be provided that are configured to receive threaded fastening elements (e.g., bolts, etc.) for temporarily fastening the detachable coupling device 4 to the load carrier.

[0058] Turning now to FIG. 6 , FIG. 6 illustrates the advanced position of the nozzles 14, with each nozzle 14 now protruding from its respective compartment 30. Also, in the advanced position, each nozzle protrudes advanced beyond the adjacent surface of the docking unit 16. Moreover, each nozzle 14 is now engaged with a respective fluid passage 18 of the detachable coupling device 4. As illustrated in the example of FIG. 6 , in the advanced position of the nozzles 14, the nozzles 14 can be configured to protrude into the fluid passage 18 of the detachable coupling device 4. Thus, the nozzles 14 provide a male part of engagement, and the fluid passage 18 provides a female part. However, it should be understood that in other exemplary embodiments, the reverse can be achieved, i.e., the nozzles form the female part and the fluid passages form the male part.

[0059] As can be seen in FIGS. 5 and 6 , each nozzle 14 can be provided with at least one seal 40, 42 configured to follow the movement of the nozzle 14. The seals can be made of rubber, plastic, or another resilient material. In the illustrated example, each nozzle includes two seals 40, 42 (i.e., a front seal 40 and a rear seal 42). Each seal 40, 42 has an inner periphery that surrounds and contacts the nozzle 14. As shown in FIG. 6 , when the nozzle 14 is in the advanced position and engaged with a respective fluid passage 18 of the detachable coupling device 4, the outer periphery of each front seal 40 seals against a circumferential wall portion of the engaged fluid passage 18. The outer periphery of each rear seal 42 seals against a circumferential wall portion of the compartment 30 from which the nozzle 14 protrudes. The front seal 40 resists rearward leakage around the outer surface of the nozzle 14. The rear seal 42 resists leakage of process medium present in the interior chamber of the medical processing device from leaking back through the compartment 30 around the nozzle 14. In this regard, it may be pointed out that the medical processing chamber may suitably have other nozzles or outlets than those illustrated in the figures. Thus, in addition to the nozzle 14 illustrated herein, which is used to provide process medium to the interior volume of the medical article (particularly into the multiple channels of the medical article), the medical processing device may also be provided with additional nozzles or other types of outlets for providing process medium to the exterior of the medical article. Such additional nozzles or outlets may be provided, for example, on one or more spray wings, which may be attached, for example, to a side wall, bottom wall, or top wall of the medical processing device.

[0060] 6, the front seals 40 of the nozzles 14 provide a tight engagement with the walls of the fluid passages 18. Due to the engagement between the nozzles 14 and the fluid passages 18, degrees of freedom are limited. In particular, in the advanced position of the nozzles 14, when the nozzles 14 engage with the fluid passages 18, the nozzles 14 prevent the detachable coupling device 4 from moving radially relative to the axial extension of any one of the nozzles 14.

[0061] The detachable coupling device 4 may be allowed to move slightly when attached to the load carrier. Fine adjustment of the detachable coupling device 4 may be achieved by designing each nozzle 14 with a tapered tip portion 15 (see FIG. 5 ). Even if the detachable coupling device 4 (with its fluid passageway 18) is not perfectly aligned with the nozzle 14, the tapered tip portion 15 will be allowed to enter the fluid passageway during movement from the retracted position to the advanced position. Continued movement of the nozzle 14 toward the advanced position will automatically adjust for any small offset of the detachable coupling device 4, ensuring that the detachable coupling device 4 is properly aligned with the docking unit 16.

[0062] As shown in Figures 1, 5, and 6, the nozzles 14 can be distributed to form one or more rows of nozzles 14. In these examples, two rows of nozzles 14 are shown. In other exemplary embodiments, any suitable number of rows (or suitable number of nozzles 14) other than those shown can be provided. When moving to the advanced position, each nozzle 14 can advance along a different respective central axis away from the sidewall 10 or docking unit 16 of the medical processing device 2. The central axes can be parallel to one another.

[0063] As previously described in connection with Figure 4, the docking unit 16 can be mounted to a bracket 44, the other side of which can be provided with an actuator. An example of such an actuator is shown in Figure 7.

[0064] 7 thus illustrates an actuator 46 positioned on the other side of the bracket 44 shown in FIG. 4. The actuator 46 includes a motor 48 and a movable actuator part 50. Before going into detail about the movement patterns of the different components, it should be pointed out that the multiple nozzle-like elements 52 visible in FIG. 7 are not the same nozzles 14 discussed with respect to the previous drawing figures. These elements 52 are connectors for connecting conduits from a source to one or more pumps that supply the process medium. The elements 52 are in fluid communication with the nozzles 14, which are not visible in this view and extend horizontally on the other side of the bracket 44.

[0065] In this example, the movable actuator part 50 is in the form of a carriage that can be moved up and down along a track 54 in the bracket 44. A motor 48 is configured to drive the movable actuator part 50 in alternating forward and reverse motions along a first geometric axis. In this illustration, the first geometric axis is a vertical axis. Thus, in this illustration, the motor 48 is configured to drive the movable actuator part 50 in alternating upward and downward motions, as indicated by double arrow A. One of the forward and reverse motions of the movable actuator part 50 causes the nozzle to move transversely to the first geometric axis from a retracted position to an extended position, and the other of the forward and reverse motions of the movable actuator part 50 causes the nozzle to return from the extended position to the retracted position. Thus, in this example, the transverse motion is horizontal motion, as indicated by double arrow B.

[0066] As illustrated in this example, translating vertical movement of the movable actuator part 50 into horizontal movement of the nozzle 14 can be achieved by providing the movable actuator part 50 with an inclined plane (e.g., an inclined rib or ridge 56, etc.). When the motor 48 pulls the actuator part 50 down along the track 54, the inclined ridge 56 pushes against a nozzle retaining part (e.g., a block 58 that holds the element 52 and the nozzle 14). More specifically, because the block 58 is prevented from moving vertically, the pushing by the inclined ridge 56 causes the block 58 to move horizontally. The block 58 holds the nozzle 14, and the nozzle 14 therefore follows the movement of the block 58, resulting in the movement of the nozzle 14 from a retracted position to an advanced position. The block 58 may be spring-loaded so that when the motor 48 moves the movable actuator part 50 up along the track 54, a spring (not shown) returns the block 58, thereby returning the nozzle 14 to the retracted position.

[0067] It should be understood that the actuator 46 shown is merely one example and that the medical processing device may be equipped with other types of actuators, motors, etc. to effectuate the change in position of the nozzle between the retracted and advanced positions.

[0068] Figure 8 is a schematic diagram of an example of automating the movement of a nozzle from a retracted position to an advanced position. Figure 8 illustrates that system 1 can include a control unit 60 configured to send a movement request 62 to an actuator 46 (such as the one illustrated in Figure 7 or any other suitable actuator) to cause the actuator 46 to move the nozzle between the retracted position and the advanced position.

[0069] 8, the system 1 may further include a position detection device 64. The position detection device 64 may be configured to indicate that the detachable coupling device 4 is positioned at the docking location in the medical processing device 2. In other words, the position detection device 64 may be configured to indicate that the detachable coupling device 4 is in a position for its fluid passage to be engaged with the nozzle. As discussed earlier in this disclosure, some examples of position detection devices 4 that may be used in the system 1 are magnetic sensors, mechanical switches, optical sensors, etc.

[0070] The position detection device 64 can be in communication with the control unit 60. Thus, when the position detection device 64 detects that the detachable coupling device 4 is positioned at a docking location (e.g., positioned in the docking unit 16, as previously discussed), the control unit 60 can receive a message 66 from the position detection device 64. The message 66 can be, for example, an analog signal (e.g., a voltage signal) or it can be a digital signal (e.g., containing digital data). The control unit 60 can be configured to send a movement request 62 to the actuator 46 when the actuator 46 receives information from the position detection device 64 that the detachable coupling device 4 is positioned at the docking location. Thus, the movement request 62 (e.g., an analog or digital signal) can control the actuator 46 to cause the nozzle to be moved from a retracted position to an advanced position so as to engage the fluid passage of the detachable coupling device 4.

[0071] The present disclosure includes systems for supplying process media to medical articles and methods of operating such systems. Among other things, the present disclosure includes systems and methods for enabling time-efficient processing (e.g., washing, cleaning, disinfecting, and / or drying, etc.) of multiple internal channels of medical articles. The present disclosure includes a docking system, an endoscope processing machine, and an expansion system including a mutually compatible endoscope washer-disinfector, an endoscope drying and / or storage cabinet, and a docking device 4 compatible with both the washer-disinfector and the drying / storage cabinet for efficient transfer therebetween. It should be understood that the various features disclosed herein are contemplated and disclosed in various combinations and subcombinations. [Explanation of symbols]
