Dual-lid reprocessor with integrated latching mechanism

Abstract

A mechanism for instrument sanitization can include a chamber housing the basin, a first lid hingedly attached to the AER, and a second lid attachable via the first lid and arranged to cover the basin when the first lid is in a closed position. A latch can be included to secure the first lid in the closed position. The second lid can translate within the basin in response to the introduction of liquid, ensuring proper liquid coverage of an instrument under sanitization in the basin. Both the first and second lids can concurrently move towards an open position through the operation of a single actuator.

[0034] This document relates to Automated Endoscope Reprocessors (AERs), more particularly on mechanisms used for enclosing the basin where surgical instruments are sanitized. AERs can include various lid or cover mechanisms to help seal the basin with respect to an external ambient environment, such as to maintain a sterile environment and contain chemical vapors during sanitization. For example, such mechanisms can include single or dual-lid approaches. A single-lid approach can involve covering the basin opening directly, e.g., via a single hinged lid. However, single-lid mechanisms can involve a challenge of achieving a reliable seal, such as relying heavily on a single gasket. A duallid approach can involve placing an "inner" lid over the basin opening and an “outer” lid atop the first lid, such as to help further contain fluid or vapor flow. However, dual-lid mechanisms can involve a challenge of actuation or handling due to physical complexity, such as having to actuate the lids in a specific order. Serial operation of two lids not only complicates the operation but also complicates cleaning and maintenance of the AER, e g.,involving disassembly of certain dual-lid mechanisms. Conventional approaches to latching mechanisms used to secure such lids generally do not allow for any significant movement of the lids once locked, which could restrict a desired functionality of the inner lid (e.g., movement corresponding to fluid filled within the basin).

[0035] The present inventors have recognized the benefits of an improved dual-lid mechanism for AERs that facilitates access into the AER basin via a single actuation. This mechanism can include a first, outer lid and a second, inner lid, where the second lid is designed to float within the basin and move vertically with a liquid level therein. Both lids can be operable via a single actuator, which can simplify the opening and closing operations by synchronizing the movement of each lid, thereby reducing a manual interaction with the device. The dual-lid mechanism can include an interface that connects the floating, second lid to the first lid. Such an interface can permit a controlled vertical and lateral movement of the floating, second lid, ensuring it functions as desired throughout the sanitization cycle. The interface can include a 'push-to-connect' connectivity, where a spring-loaded retainer attached to the first lid engages with a striker on the second lid. Such an interface facilitates attachment and detachment of the lids for normal operation and cleaning and permits the floating, second lid to adjust in vertical position based on the fluid level within the basin. In an example, the retainer mechanism can be sized and shaped to restrict undesired complete withdrawal of the striker from the gap, thus ensuring the lids remain connected during normal operation in sanitizing medical instruments. Here, the retainer mechanism can still facilitate separation of the second lid from the first lid, such as for maintenance.

[0036] FIG. 1A, FIG IB, and FIG. 1C are each schematics depicting an example of a dual-lid mechanism for an Automated Endoscope Reprocessor (AER). An AER 100 can include a chamber 102, a basin 104 disposed within the chamber, a first lid 106, and a second lid 108 configured to cover the basin 104 and enclosed by the first lid 106.

[0037] As shown in FIG. 1A, when both lids are in a closed position, the first lid 106 can enclose the chamber 102 and seal the chamber 102 from an external ambient environment. The first lid 106 can include a gasket that forms a watertight seal between the first lid 106 and the chamber 102. For example, the gasket can prevent liquid AER chemicals from seeping out of the chamber 102 during operation of the AER 100. The gasket can be made of silicone, elastomer, or other suitable materials capable of forming a watertight seal. Inan example, the gasket can be detachable from the first lid 106, for example, for cleaning purposes.

[0038] The first lid 106 can be attached to the chamber via a hinge 110. As shown in FIG. IB, the hinge can allow the first lid 106 to be pivoted away from the chamber 102, e.g., for access by a technician. In an example, the hinge 110 can allow the lid to rotate about the hinge into non-horizontal or non-vertical angles, between 5 to 85 degrees or between 15 degrees to 75 degrees. As such, the first lid 106 can be in a fully open position such that the first lid 106 substantially is coincident with the chamber or in a variety of partially open positions. In an example, the first lid 106 can be opened at an angle of between 45 degrees to 75 degrees allowing the technician access to the chamber 102 for maintenance, cleaning, or repair of the AER 100. In another example, the first lid 106 can be pivoted further beyond the fully open position and the user can be provided with easier access to the fully upper and lateral parts of the inside chamber. In an example, the first lid 106 can be held open by one or more struts. For example, the one or more struts can be pneumatic, spring, mechanical, or electromechanical struts. In an example, the first lid 106 can be maintained at the open or partially open angle without a need for the lid to be manually held or otherwise propped.

[0039] The second lid 108 can be arranged such as to cover the basin 104 while the first lid 106 is in a closed position. The second lid 108 can be attachable with the first lid 106 via an interface therebetween. Such an interface can permit linear travel of the second lid with respect to the first lid. Such “linear travel” refers to travel of the second lid 108 toward or away from the first lid 106, regardless of an angular position of the first lid 106 (e.g., in an open or partially open position). For example, the second lid 106 can be formed of a material with a buoyancy to float upon introduction of liquid (e.g., distilled water or liquid detergent) within the chamber 102. Such a “floating lid” capability of the second lid 108 in the AER 100 can help facilitate or maintain contact between the cleaning medium (e.g., the liquid detergent) and the instrument to be cleaned (e.g., an endoscope). Meanwhile, the second lid can be moveable with respect to the first lid to avoid excess force applied to the instrument that is being cleaned while the AER 100 is in operation. For example, the second lid 108 can help maintain the instrument in position within the chamber 102 and ensure that the instrument is fully submerged in cleaning medium. The second lid 108 can also help dampen vibration or noise during operation of the AER 100, as the second lid 108 can act as a baffle to substantially reduce noise produced by thecirculating fluid within the chamber 102. The second lid 108 can be made of a material such as plastic or polymeric material and can include one or more support structures or ribs. In an example, the second lid 108 can be formed of a unitary plastic component. For example, the second lid can be injection molded and made of polypropylene or other suitable material.

[0040] As depicted in FIG. 1C, the second lid 108 can be removable from the first lid 106, at the interface therebetween, such as for maintenance or cleaning of the second lid 108. For example, such removal can allow a technician to clean the rim or underside of the second lid 108, such as after a requisite number of cleaning cycles or when the AER is being prepared for a certain endoscope cleaning procedure. In an example, the second lid 108 can be attached to the first lid 106 in a snap-fit manner or other suitable attachment mechanism that allows for easy removal. Further attachment / detachment approaches to the interface between the first lid 106 and the second lid 108 will be discussed below with respect to FIG. 3 A, FIG. 3B, FIG 3C, FIG. 3D, FIG. 3E, and FIG. 3F. In addition, as shown in FIG. 1A, the second lid 108 can include a groove configured to receive a distal end of the first lid 106 in a snap-fit manner to ensure proper attachment therebetween. In an example, the distal end of the first lid 106 can have a corresponding shape to the groove of the second lid 108.

[0041] An instrument to be cleaned can be introduced within the chamber 102, e g., via moving the first lid 106 toward an open or a partially open position, and the second lid 108 can be at least partially in contact with the instrument during a sanitization cycle. An aperture for through-hole serving as a fluid displacement means (e.g., as a conduit for pressurized gas and / or a vacuum from the endoscope tip to purge or pull in cleaning medium from the first lid 106) can be disposed in a region of the chamber 102 or the basin 104. As discussed further with respect to FIG. 2, FIG. 3C, FIG. 6A, FIG. 6B, FIG. 6C, and FIG. 6D, a single actuator can facilitate user access to the basin 104, such as to at least partially open each of the first lid 106 and the second lid 108 via a common actuation.

[0042] FIG. 2 illustrates an example of an Automated Endoscope Reprocessor (AER) with both lids in an open position. The AER 100 can include the chamber 102, the basin 104 disposed within the chamber, the first lid 106, and the second lid 108 configured to cover the basin 104 and enclosed by the first lid 106. The AER 100 can be arranged disposed atop or adjacent to a sterilization unit, for example, sterilization unit which can supply fluid to sterilize an instrument held in the basin.

[0043] In an example, the first lid 106 can include a window for allowing view into the chamber 102. The first lid 106 can be moved toward the closed position (as depicted in the schematic of FIG. IB) and secured in the closed position via at least one latch, such as a spring-loaded latch. The chamber 102 can have a generally rectangular shape, for example. In an example, the basin 104 can include a U-shape or L-shape, configured to securely hold an instrument within the basin 104. In an example, one or more manifolds can be provided within the chamber 102 for cleaning that connects to an instrument channel or other internal cleaning site of the instrument. For example, one or more endoscope ports can be attached to the manifolds and can provide a fluid passage for cleaning medium to enter and exit into each channel (e.g., a biopsy channel, an air / water channel) of an endoscope. The basin can include one or more apertures 204 for introducing cleaning fluid to the basin. For example, the one or more apertures 204 can include jets, nozzles, or spray nozzles which are connected to valves that can control the flow of fluid into the instrument. For example, the jets can be installed along the internal surfaces and create a spray of fluid that covers the entirety of the internal surface area. The U-shaped basin can be made of metal, ceramic or plastic and can include one or more apertures 204 disposed along a center section, for example in the bottom of a basin; that can correspond to ports in an instrument for introducing and removing fluids.

[0044] In an example, the second lid 108 can be at least partially shaped to reflect (i) the shape of the endoscope, with internal features, such as one or more channels being shaped to follow those of the endoscope being cleaned or (ii) a shape of the basin, such as to closely match the shape or clearance of the basin 104. As shown in FIG. 2, the second lid 108 can be formed of a substantially translucent or transparent material 202 structured to allow a user to view an interior of the basin 104 and the second lid 108. The translucent material can also facilitate an illuminating device (e.g., LED, lights) which can be disposed within the second lid 108 to cast light upon an interior of the second lid 108 as well as an interior of the basin 104.

[0045] As depicted in FIG. 2, the second lid 108 can be attachable via a “push-to- connect” mechanism, e.g., including at least one latch and at least one striker. For example, the latch can be mounted to one of the first lid 106 or the second lid 108, and the striker can be mounted to the other of the first lid 106 or the second lid 108. Examples of such latch and striker mechanisms are depicted in greater detail in, and described with respect to, FIG. 3E and FIG. 3F. In an example, the push-to-connect mechanism can restrictundesired complete detachment of the second lid 108 from the first lid 106 (e.g., to restrict the second lid falling onto the basin 104 or otherwise in the chamber 102) while still allowing a desired complete detachment of the second lid 108 from the first lid 106. For example, the push-to-connect mechanism can facilitate a “pull-to-disconnect” connectivity, where a requisite amount of pulling force, e.g., in a direction away from the first lid 106, serves to detach the second lid 108 from the first lid 106 For example, the requisite amount of pulling force can be within a range of about 20 N to about 200 N, such as being within a range of about 50 N to about 150 N. In some examples, a desired tab, handle, button, etc., can be provided to facilitate a gripping or grasping portion that overcomes the necessary amount of force in pulling the second lid 108 away from the first lid 106.

[0046] FIG. 3 A is a schematic depicting an example of a dual-lid mechanism, showing a second lid covering a basin of an Automated Endoscope Reprocessor (AER) 100. The schematic shows a cross section further detailing an interface 302 between the first lid 106 and the second lid 108, such as to allow for linear travel of the second lid 108 with respect to the first lid 106 (upward and downward with respect to FIG. 3 A) while still facilitating a same actuation for both the first lid 106 and the second lid 108. Each of the first lid 106 and the second lid 108 can concurrently move toward an open position, via a single actuator, to uncover the basin and expose the basin 104 to the external ambient environment (e.g., upon hinged movement of the first lid 106 as depicted in FIG. IB).

[0047] In an example, the second lid 108, during the first lid 106 being in the closed position, is arranged such as to move within the basin (e.g., toward the first lid 106) based on liquid being introduced in the basin. For example, the first lid 106 and the second lid 108 are each attachable at an interface 302 therebetween. At or near the interface 302, the first lid 106 can define a gap 304 to slidingly receive at least a portion of a striker 306 attached to the second lid. As depicted in FIG. 3 A, the AER 100 can include a plurality of interfaces 302, e.g., to help maintain a parallel orientation of the second lid 108 with respect to the first lid 106 during linear travel (e g., floating) of the second lid 108.

[0048] FIG. 3B, FIG. 3C, and FIG. 3E, are each cross-section views of an Automated Endoscope Reprocessor (AER), displaying a dual-lid mechanism. In an example, the first lid 106 can include mounting features (e.g., via mounting plates or blocks, threads, inserts, welds, adhesives, etc.) for attaching a retainer mechanism 312. For example, the retainer mechanism 312 can include a latch, latch holder, spring, and / or other bracing, allconfigured to sufficiently restrain and retain at least a portion of the striker 306 within the gap 304 against undesired removal. For example, the spring in compression against the latch holder can be configured to push a protrusion of the latch into contact with at least a portion of the striker 306. In such an example, a pulling force on the retainer mechanism 312 (e.g., at an end opposite from the protrusion) over the requisite amount of force to overcome the spring compression can allow the latch to no longer contact at least a portion of the striker 306, removing the restraint retained by the retainer mechanism 312. As shown in FIG. 3C and FIG 3D, during the first lid 106 being in the closed position, the second lid can also be held in the closed position via the interface 302 (e g., due to physical contact between the retainer mechanism 312 and the striker 306). Despite being held in the closed position via the interface 302, the second lid 108 is permitted to travel toward the first lid 106, such that at least a portion of the striker 306 travels further into the gap 304, e.g., based on a rising fluid level in the basin 104.

[0049] FIG. 3B and FIG 3C also each depict the actuator 310. The actuator 310 can control the hinged opening of the first lid 106 and, by nature of the interface 302 holding the second lid 108 to the first lid 106, the actuator 310 can also control synchronized movement of the second lid 108. In an example, the actuator 310 can be mounted to the chamber 102, such as at or near an outer surface. The actuator 310 can also be mounted to other parts of the AER 100 such as at a frame or attached, at least in part, to the basin 104. Herein, while the actuator 310 is depicted and described as a “single actuator”, it need not be limited to a single device. For example, a plurality of actuators can be arranged in conjunction with one another to achieve a “single actuation”, such that they do not necessarily need to operate or be triggered independent of one another. By “single actuator” and “single actuation”, it is intended herein to describe that both the first lid 106 and the second lid 108 can be opened without requiring separate, respective actuators for each lid. Examples of mechanisms that can be included in the actuator 310 include, e g., electro-mechanical devices (e.g., mechanical actuators, hydraulics, pneumatics, piezoceramic devices, motors, etc.).

[0050] FIG. 3E and FIG. 3F each illustrate components of respective examples of a retainer mechanism for a dual-lid mechanism of an Automated Endoscope Reprocessor (AER). Each of FIG. 3E and FIG. 3F depict a retainer mechanism 312 and a corresponding striker 306. In an example, at least one of first lid 106 or the second lid 108 can include the retainer mechanism 312 including a latch mechanism to restrict complete withdrawalof a corresponding striker 306 from the gap. In an example, the latch of the retainer mechanism 312 can be moveable via a deployed position, wherein the retainer mechanism restricts complete withdrawal of the striker 306 from the gap 304, and a retracted position wherein the retainer mechanism 312 permits complete withdrawal of the striker 306 from the gap 304 (e.g., for removal or maintenance of the second lid 108). For example, the latch of the retainer mechanism 312 can include opposing elements 324, such as rotating or rolling bars, sliders, pinchers, gears, etc., configured to move toward each other and impede the gap 304. For example, the opposing elements 324 can be spring biased toward each other such as to impede the gap 304 and maintain the deployed position. A corresponding striker 306 can include a catch feature 326, such as an angled or t-shaped surface or protrusion. The catch feature 326 can be sized and shaped such as to impede removal of the striker 306 from the gap 304 while the opposing elements 324 are in the deployed position.

[0051] FIG. 4A, FIG. 4B, FIG. 4C, FIG. 4D and FIG. 4E illustrate another example of the dual -lid mechanism of an Automated Endoscope Reprocessor 100. FIG. 4A shows the Automated Endoscope Reprocessor (AER) 100 in the open position, with both lids disconnected. In this configuration, a first lid 106 can be in an open position and uncoupled from a second lid 108, e.g., while the second lid 404 is in a closed position. FIG. 4B shows the Automated Endoscope Reprocessor (AER) 100 in the open position, with both the first lid 106 and the second lid 108 connected, each in the open position. In an example, the first lid 106 and the second lid 108 can be connected and disconnected from each other magnetically alternatively or additionally to other fastening, retaining, or striker mechanisms.

[0052] FIG. 4D depicts an individual housing block 406 of FIG. 4C. In an example, the first lid 106 can include one or more housing blocks 406 each including a cavity 408, e.g., sized and shaped to interface with a second lid handle 410. For example, a one or more second lid handles 410 can be attached to the second lid 108. In an example, the housing blocks 406 can be formed of or otherwise include a magnetic or ferromagnetic material. FIG. 4C shows the first lid 106 and the second lid 108 each in a closed position. In this configuration, the one or more second lid handles 410 each occupy a respective cavity 408 of a corresponding housing block 406, e.g., at least partially coupled via magnetic attraction.

[0053] FIG. 4E depicts the second lid 108 including the one or more second lid handles 410, e.g., located and attached near opposite sides of the second lid 108. In an example, the one or more second lid handles 410 can each include a connector plate 412 configured to pair with a corresponding housing block 406, e.g., formed of or otherwise including a magnetic material. For example, an individual connector plate 412 can be attached toward a distal end of a corresponding lid handle 410 In an example, an individual connector plate 412 can translate laterally with respect to a respective second lid handles 410, e g., from a base of the handle stop and toward the distal end of the corresponding second lid handle 410. As such, during coupling between a housing block 406 and a corresponding connector plate, the one or more second lid handles 410 can translate vertically, e g., toward and through the cavity 408 of a corresponding housing block 406. Such an arrangement can facilitate the second lid 404 to rise or fall along with a fluid level and with respect to the basin and the first lid 106, while maintaining attachment of the second lid 108 to the first lid via the (e.g., magnetic) coupling between the connector plates 412 and their corresponding housing blocks.

[0054] In an example, the second lid 108 can be uncoupled from the first lid 106, e g., by separating the connector plates 412 from their respective housing blocks 406. For example, detachment of the second lid 108 from the first lid 106 can facilitate removal of the second lid 108, such as to ease maintenance or cleaning.

[0055] FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D and FIG. 5E illustrate another example of the dual -lid mechanism of an Automated Endoscope Reprocessor 100 using a floating lid post mechanism. FIG. 5 A shows the second lid 108 can include one or more floating lid posts 504, e.g., located toward opposite sides of the second lid 108. The one or more floating lid posts 504 can be attached to the second lid 108 via respective post screws 506. For example, a pair of floating lid posts 504 can be tied to each other via a lid post support beam 508In an example, the pair of floating lid posts 504 can alternatively or additionally be connected to each other, e.g., toward distal ends of the posts 504, via an attachment bracket 512.

[0056] FIG. 5B shows a side view of an individual floating lid post 504. In an example, the floating lid post 504 can include a retainer 518 located at or near a distal end of the post 504. The floating lid post 504 can also include an attachment bracket 512 and a bracket stop 520. The attachment bracket 512 can translate vertically with respect to the floating lid posts 504, e.g., along a length between the retainer 518 and the bracket stop520. Such a configuration can facilitate rising and falling of the second lid 108, with respect to the basin 104 and the first lid 106 (as depicted in FIG. 3A), such as to allow the second lid 108 and move vertically according to a liquid level in the basin. In an example, a maximum travel distance of the attachment bracket 512, along the length between the retainer 518 and the bracket stop 520, can be within a range of about 5 millimeters (mm) and about 100 mm, such as within about 10 mm and about 50 mm, such as about 16 mm. In an example, as depicted in FIG. 5C, the attachment bracket 512 can be further connected to a connecting bracket 514. For example, the connecting bracket 514 can extend between the attachment bracket 512 and the first lid 106. In an example, the connecting bracket 514 can be coupled to the attachment bracket 512, e.g., via a magnetic material, a tape, an adhesive, a screw, a fastener, etc.

[0057] FIG. 5D depicts an individual floating lid post 504 during a condition where less than a specified amount of liquid fills the basin 104 (e.g., the basin is substantially void of cleaning fluid). In this example, a lack of liquid filling the basin 104 can facilitate the second lid 108 to be in a first position toward the basin 104 and retained to the attachment bracket 512 via the retainer 518. In an example, the retainer 518 can include a removable component (e.g., a thumb screw) to help prevents the attachment bracket 512 from detaching from the floating lid post 504 while facilitating removal for ease in maintenance and cleaning. FIG. 5E depicts an individual floating lid post 504 during a condition where a specified amount of liquid fills the basin 104. Here, the liquid in the basin 104 can contribute toward the second lid 502 rising or floating with respect to the basin 104. This can facilitate the attachment bracket 512 to translate with respect to the floating lid post 504, e.g., toward the bracket stop 520. In an example, the bracket stop 520 can constrict the attachment bracket 512 from translating further toward the lid post support beam 508 or the second lid 502.

[0058] FIG. 6A, FIG. 6B, FIG. 6C, and FIG. 6D each illustrate an example of an Automated Endoscope Reprocessor (AER) in operation and use. As shown in FIG. 6A, the AER can be actuated, via a single actuator, toward an open position where first and second lids both allow access to a wash basin within the chamber of the AER. As shown in FIG. 6B, the second lid can be disconnected from the first lid, such as by unpairing or unmating an interface between the first and second lid. Thus, if desired, the second lid can be moved toward the closed position (as depicted in FIG. 6B) while the first lid is left in the open position. As shown in FIG. 6C, the first and second lids can each be moved toward theclosed position via the single actuator. As shown in FIG. 6D, liquid can be introduced into the basin. The second lid can remain closed, concealing the basin, while the second lid is allowed to move toward the first lid based on rising liquid levels within the basin.

[0059] FIG. 7 is a flowchart describing a process for disinfecting a surgical instrument within an enclosed basin of an Automated Endoscope Reprocessor (AER).

[0060] At 702, a surgical instrument can be received within a basin of the AER, e.g., the basin being housed within a chamber of the AER.

[0061] At 704, a lid mechanism actuator can be triggered. Such a lid actuator can be arranged such as to control movement of both a first and second lid, e.g., such as not requiring independent movement of each of the first and second lid to synchronize opening / closing thereof. For example, triggering the lid mechanism actuator can involve transitioning the first lid toward a closed position. Such a transition can include providing a fluid seal between the chamber and the external ambient environment, e.g., facilitating that the sanitization environment remains uncontaminated during an instrument sanitization operation. Simultaneously with the first lid being moved to the closed position, the second lid, which is attached to the first lid, can also transition toward a closed position via the triggering of the lid mechanism actuator. The second lid can move toward the basin such as to cover the basin, promoting a surgical instrument being fully enclosed.

[0062] At 706, with both lids in the closed position, a liquid disinfectant can be introduced into the basin. For example, introduction of the liquid disinfectant to the basin can involve spraying the disinfectant via jets or nozzles within the basin. As the liquid disinfectant is introduced, the second lid can be caused (e.g., via rising levels of liquid disinfectant within the basin) to move vertically towards the first lid within the basin. The distance of this vertical travel can correspond with the amount of liquid disinfectant introduced. Such an arrangement can facilitate that the second lid adjusts according to the liquid level, maintaining desired conditions for the disinfection process such as submersion of the instrument. This vertical movement can be facilitated by an interface between the first and second lids, which permits linear travel of the at least a portion of the second lid within a gap of the first lid. In an example, the disinfectant can be drained from the basin, e.g., following a sanitization operation including the instrument being immersed in the liquid disinfectant for a specified time.

[0063] Optionally, at 708, the second lid can be uncoupled from the first lid for removal or maintenance. Such uncoupling can include moving a retainer mechanism, which is arranged on at least one of the lids, between a deployed position and a retracted position. Here, the deployed position involves the retainer mechanism restricting complete withdrawal of a striker attached to the second lid from a gap defined by the first lid, and the retracted position involves permitting complete withdrawal of the striker from the gap for removal or maintenance of the second lid.

[0064] FIG. 8A is a perspective view of a basin of an Automated Endoscope Reprocessor (AER), showing a magnetic dual-lid mechanism with a second lid connected. FIG. 8B is an orthographic view of a second lid. In an example, the Automated Endoscope Reprocessor (AER) 100 (as depicted in FIG. 4A) can include a first lid 106 and the second lid 108 sized, shaped, and formed of materials such as to be connected and disconnected from each other magnetically. As shown in FIG. 8A, the basin 104 can receive the second lid 108 (e.g., visible when a first lid is in an open position), and the second lid 108 can include a mechanism for attachment and detachment from the first lid. As shown in FIG. 8B, the second lid 108 can include one or more magnetic extensions 802 for removably coupling with the first lid (e.g., for coupling / decoupling with a corresponding magnetic or ferromagnetic material included in the first lid 106 as depicted in FIG. 4C). For example, the one or more magnetic extensions 802 can each occupy a respective receiving portion of the first lid, e.g., at least partially coupled via magnetic attraction between a magnetic extension 802 and ferromagnetic material (e.g., 430 stainless steel or 410 stainless steel) of the first lid. Here, similar as described with respect to FIG. 4A, FIG. 4B, FIG. 4C, FIG. 4D, and FIG. 4E, the second lid 108 can be uncoupled from the first lid, e.g., by separating the magnetic extensions 802 from their respective receiving portions. For example, detachment of the second lid 108 from the first lid can facilitate removal of the second lid 108, such as to ease maintenance or cleaning.

[0065] FIG. 8E is a side view of a second lid. FIG. 8C is a perspective view of a bearing, and FIG. 8D is an exploded view of a magnet-bearing assembly, used in the second lid of FIG. 8E. In an example, the one or more magnetic extensions 802 can be formed of a magnet-bearing assembly 806. Similar to that described with respect to lid motion in each of the other examples described herein, the attachment of the second lid 108 to the first lid can permit linear travel of the second lid 108, such as to allow for the second lid 108 to float based on an amount of fluid filling the basin 104. Here, a bearing 804 can beincluded, with the bearing 804 sized and shaped to promote control of such a floating motion and to mitigate certain jamming or undesired rotational challenges introduced by certain other attachment mechanisms. For example, the bearing 804 can be formed of plastic (e.g., nylon, acetal, polytetrafluoroethylene (PTFE), etc.) or other materials that are chemically resistant to detergents and chemicals used in the AER (e g., STERIS® RAPICIDE®). In an example, the bearing 804 can help form a magnet-bearing assembly 806, which can also include one or more magnets 810 and a housing 812 (e.g., the housing 812 formed of Polyvinyl Chloride (PVC)). As shown in FIG. 8E, a rod 814 can extend through a lumen of each magnet-bearing assembly 806, such that a bearing 804 of an individual magnet-bearing assembly grips the corresponding rod 814 and permits motion of the magnet-bearing assembly 806 along the rod 814. In an example, an individual rod 814 can additionally include a collar to at least partially restrict a length, along the rod 814, that the magnet-bearing assembly 806 is permitted to travel.
