[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 604,663, filed November 30, 2023, the disclosure of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates generally to medical fluid containers and methods, and more specifically to a container and tubing kit for supplying fluids and / or gases to an endoscope. Background Technology

[0003] As is customary, endoscopic devices are widely used to perform diagnostic and / or therapeutic procedures. During endoscopic procedures, physicians can use a combination of air, irrigation, and lens cleaning as a means of flushing out debris, cleaning optics, and inflating the working lumen. For example, sterile water can be used during the procedure to irrigate the working lumen and / or remove organic matter (e.g., clots, feces, or other clumps) from the area of ​​interest. This can be achieved by spraying a low-velocity jet of water from an orifice at the tip of the endoscope. Furthermore, during endoscopic procedures, the video lens located at the distal end of the endoscope for navigation and visualization of target tissue can be easily contaminated with blood, mucus, and other debris. Physicians need to be able to clean the lens and working lumen throughout the procedure. To generate lens cleaning, a connector is attached to the endoscope's umbilical cord via a tubing kit. The tubing kit delivers air from the endoscope's umbilical cord to a water container or pressure vessel. A suction tube within this container or pressure vessel is in fluid contact with water and is connected to the connector. This allows pressure to be built into a water bottle or pressure vessel to deliver water along the tubing to the distal end of the endoscope, thereby cleaning the endoscope lens.

[0004] Endoscopic fluid delivery for both lens cleaning and irrigation processes can include a flexible tubing kit with a threaded cap that connects to a one-liter (L) semi-rigid bottle containing sterile water for irrigation. Commercially available tubing kits are available as either conventional dual-bottle tubing kits or hybrid tubing kits. Conventional tubing kits consist of two separate tubing kits connected to two separate bottles of sterile water. One kit connects to the one-liter sterile water bottle, while the second kit connects to a second bottle for irrigation. In contrast, hybrid tubing kits consist of a single tubing kit connected to a single one-liter water source, and this single system performs both irrigation and lens cleaning functions.

[0005] In some cases, it may be desirable to use readily available solution bags for sterile water or saline instead of bottles. Using solution bags can offer numerous advantages over current bottle-driven systems, including, but not limited to, allowing users to customize the volume of the fluid reservoir to suit their practical needs. For example, users can use readily available one-liter, two-liter, or three-liter solution bags, thereby reducing or avoiding the need to repeatedly change one-liter bottles throughout the surgical day.

[0006] Solution bags may require suspension. However, many endoscopy rooms have limited space and therefore no room for a separate intravenous (IV) pole to suspend the tubing kit solution bags. Therefore, a hanger is needed that would allow the solution bags to be suspended from an endoscopy cart, which typically houses capital equipment and one-liter bottles used in currently commercially available tubing kits. With these factors in mind, improvements to this disclosure may be useful. Summary of the Invention

[0040] While this disclosure can be modified and alternatively implemented in various ways, its details have been illustrated by way of example in the accompanying drawings and will be described in detail. However, it should be understood that the invention is not intended to be limited to the specific embodiments described. Rather, it is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure. Detailed Implementation

[0041] This disclosure will now be described with reference to exemplary medical systems that can be used in endoscopic medical procedures. However, it should be noted that reference to this particular procedure is provided for convenience only and is not intended to limit the scope of this disclosure. Those skilled in the art will recognize that the core concepts of the disclosed apparatus and related methods of use can be applied to any suitable procedure (medical or other). This disclosure can be understood with reference to the following description and accompanying drawings, in which the same or similar reference numerals will be used to refer to the same or identical parts.

[0042] The term "distal" refers to the portion furthest from the user when the device is introduced into the patient's body. In contrast, the term "proximal" refers to the portion closest to the user when the device is placed into the patient's body. As used herein, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not necessarily include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. The term "exemplary" is used in the sense of "example" rather than "ideal." Further, as used herein, the terms "about," "approximately," and "substantially" indicate a range of values ​​within + / - 10% of the stated or implied values. Additionally, terms indicating the geometry of a component / surface refer to both exact and approximate shapes.

[0043] The embodiments of this disclosure are described with specific reference to bottles (e.g., containers, reservoirs, etc.) and tubing assemblies or kits. It should be understood that such embodiments can be used to supply fluids and / or gases to an endoscope for a variety of purposes, including, for example, facilitating patient inflatation, lens cleaning, and / or irrigating the working channel to aid in flushing / aspiration of debris during endoscopic procedures.

[0044] Although this disclosure includes a description of containers and tubing kits suitable for use with endoscope systems to supply fluids and / or gases to endoscopes, the devices, systems, and methods described herein can be implemented in other medical systems requiring fluid and / or gas delivery and for a variety of other purposes.

[0045] It should be noted that references to "embodiments," "some embodiments," or "other embodiments" in the specification indicate that the described embodiments may include specific features, structures, or characteristics, but each embodiment may not necessarily include that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Further, when a specific feature, structure, or characteristic is described in conjunction with an embodiment, whether explicitly described or not, implementing such a feature, structure, or characteristic in conjunction with other embodiments will be within the knowledge of those skilled in the art, unless expressly stated otherwise. That is, the individual elements described below, even if not explicitly shown in a specific combination, are considered to be combinable or arrangeable with each other to form other additional embodiments or to supplement and / or enrich the described embodiments, as will be understood by those skilled in the art.

[0046] As used in this specification and the appended claims, unless the context clearly indicates otherwise, the singular forms “a” and “the” include plural references. As used in this specification and the appended claims, the term “or” is generally used in its sense that it includes “and / or”, unless the context clearly indicates otherwise.

[0047] As is customary, endoscopic devices are widely used to perform diagnostic and / or therapeutic procedures. During endoscopic procedures, physicians can use a combination of air, irrigation, and lens cleaning as a means of flushing out debris, cleaning optics, and inflating the working lumen. For example, sterile water can be used to irrigate the working lumen during the procedure. Furthermore, during endoscopic procedures, the video lens located at the distal end of the endoscope, used for navigation and visualization of target tissue, can be easily contaminated with blood, mucus, and other debris. To generate lens cleaning, a connector is attached to the endoscope's umbilical cord via a tubing kit. The tubing kit delivers air from the endoscope's umbilical cord to a water container or pressure vessel. A suction tube within this container or pressure vessel is in fluid contact with water and is connected to the connector. This allows pressure to be built into the water bottle or pressure vessel to deliver water along the tubing to the distal end of the endoscope, thereby cleaning the endoscope lens. Tubing kits used to provide irrigation and / or lens cleaning fluids can typically be used for a 24-hour period across multiple endoscopic procedures. However, the same endoscope is not used for multiple patients and must be changed between procedures. At the end of the procedure, the connector is disconnected from the umbilical cord. Residual water in the tubing kit may spill onto the floor upon disconnection. Additionally, residual pressure in the connector or pressure vessel can create a siphon vacuum, causing all water in the container / pressure vessel to spill onto the floor via the tubing kit. Means to prevent water leakage and / or siphoning can prevent the user from cleaning water from the floor, prevent damage to capital equipment near or below the tubing connector, or eliminate the need for the user to prepare additional water containers or refill them for the next procedure. This document discloses devices and systems for preventing water from siphoning and / or leaking from water bottles and / or tubing kits after surgery.

[0048] refer to Figures 1 to 2 The illustration depicts an exemplary endoscope 100 and system 200, which may include an elongated shaft 100a inserted into a patient's body. A light source 205 supplies illumination light to a distal portion 100b of the endoscope 100, which may house an imager (e.g., a CCD or CMOS imager) (not shown). The light source 205 (e.g., a lamp) is housed in a video processing unit 210, which processes signals input from the imager and outputs the processed video signal to a video monitor (not shown) for viewing. The video processing unit 210 also serves as a component of an air / water supply loop by housing a pressure pump 215 (e.g., an air supply pump) within the unit.

[0049] The endoscope shaft 100a may include a distal end 100c disposed at a distal portion 100b of the shaft 100a and a flexible bend 105 proximal to the distal end 100c. The flexible bend 105 may include a hinge joint (not shown) to assist in swivel of the distal end 100c. On the end face 100d of the distal end 100c of the endoscope 100 is a gas / lens cleaning nozzle 220 for supplying gas to inflate the patient at the treatment area and for supplying water to clean the lens covering the imager. An irrigation opening 225 in the end face 100d supplies irrigation fluid to the patient's treatment area. The end face 100d of the distal end 100c may also include an illumination window (not shown) for transmitting illumination light to the treatment area, and an opening 230 leading to a working channel 235 extending along the shaft 100a for passing tools to the treatment area. The working channel 235 extends along the shaft 100a to the proximal channel opening 110, which is located distal to the operating handle 115 of the endoscope 100. The biopsy valve 120 can be used to seal the channel opening 110 to prevent unwanted fluid leakage.

[0050] The operating handle 115 may be provided with knobs 125 for providing remote four-way steering of the distal end via wires connected to articulated joints in the flexible portion 105 (e.g., one knob controls up-and-down steering, while another controls left-and-right steering). Multiple video switches 130 for remotely operating the video processing unit 210 may be arranged on the proximal side of the handle 115. Additionally, the handle 115 is provided with a dual valve well 135. One of the valve wells 135 may receive a gas / water valve 140 for operating the injection gas and lens water supply. Gas supply lines 240a and lens cleaning supply lines 245a extend distally from the gas / water valve 140 along the shaft 100a and converge at the distal end 100c proximal to the gas / cleaning nozzle 220. Figure 2 Another valve well 135 receives a suction valve 145 for operating suction operations. A suction supply line 250a extends distally from the suction valve 145 along shaft 100a to a junction in fluid communication with the working passage 235 of the endoscope 100.

[0051] The operating handle 115 is electrically and fluidly connected to the video processing unit 210 via a flexible umbilical cord 260 extending between the operating handle and the video processing unit 210, and a connector portion 265. The flexible umbilical cord 260 includes a gas (e.g., air or CO2) supply line 240b, a lens cleaning supply line 245b, a suction supply line 250b, an irrigation supply line 255b, a light guide (not shown), and an electrical signal cable (not shown). The connector portion 265 connects a light source 205 in the video processing unit to the light guide when inserted into the video processing unit 210. The light guide extends along the length of the umbilical cord 260 and the endoscope shaft 100a to transmit light to the distal end 100c of the endoscope 100. The connector portion 265 also connects an air pump 215 to the gas supply line 240b in the umbilical cord 260 when inserted into the video processing unit 210.

[0052] A water reservoir or container 270 (e.g., a water bottle) is fluidly connected to the endoscope 100 via a connector portion 265 and an umbilical cord 260. A gas supply line 240c extends from one end of an air gap 275 located between the top 280 (e.g., a bottle cap) of the reservoir 270 and the remaining water 285 in the reservoir to a detachable gas / lens cleaning connector 290 on the outside of the connector portion 265. The detachable gas / lens cleaning connector 290 may be detachable from the connector portion 265 and / or the gas supply line 240c. A gas supply line 240b from the umbilical cord 260 branches in the connector portion 265 to be in fluid communication with the gas supply line 240c and with an air pump 215 at the detachable gas / lens cleaning connector 290. A lens cleaning line 245c extends from one end located at the bottom of reservoir 270 through the top 280 of reservoir 270 to a detachable connector 290 on connector portion 265 identical to that of gas supply line 240c. In other embodiments, these connectors may be separate and / or independent of each other. Connector portion 265 also has a detachable irrigation connector 293 for the irrigation supply line (not shown) extending from an irrigation water source (not shown) to the irrigation supply line 255b in umbilical conduit 260. Detachable irrigation connector 293 may be detachable from connector portion 265 and / or irrigation supply line (not shown). In some embodiments, irrigation water is supplied from a water source (not shown) independent of water reservoir 270 via a pump (e.g., a peristaltic pump). In other embodiments, the irrigation supply line and lens cleaning line 245c may draw water from the same reservoir. The connector portion 265 may also include a detachable suction connector 295 for the suction supply lines 250b and 250a, which fluidly connects a vacuum source (e.g., hospital ward suction) (not shown) to the umbilical cord line 260 and the endoscope 100. The detachable suction connector 295 may be detachable from the connector portion 265 and / or the suction supply lines 250b and / or the vacuum source.

[0053] Gas supply line 240b and lens cleaning supply line 245b are fluidly connected to valve well 135 for gas / water valve 140 and are configured such that operation of gas / water valve 140 in the well controls the supply of gas or lens cleaning water to the distal end 100c of endoscope 100. Suction supply line 250b is fluidly connected to valve well 135 for suction valve 145 and is configured such that operation of suction valve in the well controls suction at the working channel 235 of endoscope 100.

[0054] refer to Figure 2This section explains exemplary operation of an endoscope system 200, which includes an endoscope, such as the endoscope 100 described above. Airflow from an air pump 215 in the video processing unit 210 is directed through a connector portion 265 and via a gas supply line 240b in the umbilical conduit 260 to a gas / water valve 140 on the operating handle 115, and via a connector 290 on the connector portion 265 to a water reservoir 270 via a gas supply line 240c. When the gas / water valve 140 is in the neutral position, the user's finger is not on the valve, and air is allowed to flow from the valve to the atmosphere. In the first position, the user's finger is used to block the vent to the atmosphere. Gas is allowed to flow down the gas supply line 240a from the valve 140 and out from the distal end 100c of the endoscope 100, for example, to inflate the patient's treatment area. When the gas / water valve 140 is pressed down to the second position, gas is blocked from leaving the valve, allowing the pressure of the air supplied from the air pump 215 in the water reservoir 270 to rise. Pressure is applied to the water source, causing water to exit from the lens cleaning line 245c, pass through the connector portion 265, the umbilical line 260, through the gas / water valve 140, and down the lens cleaning supply line 245a, where it merges with the gas supply line 240a, and then exits the distal end 100c of the endoscope 100 via the gas / lens cleaning nozzle 220. The air pump pressure can be calibrated to provide lens cleaning water at a relatively low flow rate compared to the irrigation water supply.

[0055] The flow rate of the lens cleaning water is controlled by the gas pressure in the water reservoir 270. As water is expelled from the water reservoir 270 through the lens cleaning line 245c and the gas pressure in the water reservoir 270 begins to drop, the air pump 215 replaces the lost air supply in the water reservoir 270 to maintain a substantially constant pressure, which in turn provides a substantially constant flow rate of lens cleaning water. In some embodiments, a filter (not shown) may be placed in the path of the gas supply line 240c to filter out unwanted contaminants or particles, preventing them from entering the water reservoir 270. In some embodiments, an outflow check valve or other one-way valve configuration (not shown) may be placed in the path of the lens cleaning supply line to help prevent water from flowing back into the reservoir 270 after it has passed through the valve.

[0056] Compared to lens cleaning water, irrigation water typically requires a relatively high flow rate because its primary purpose is to remove debris obstructing the user's view in the patient's treatment area. As described, irrigation is typically achieved using a pump (e.g., a peristaltic pump). In embodiments with a separate water source for irrigation, tubing placed at the bottom of the water source passes through the top of the water source and into the head on the upstream side of the pump. Tubing on the downstream side of the pump is connected via an irrigation connector 293 on connector portion 265 to irrigation supply line 255b in umbilical cord 260 and irrigation supply line 255a of endoscope 100. When irrigation water is needed, fluid is pumped from the water source by operating the irrigation pump (e.g., by pressing a foot switch (not shown)), and the fluid flows through irrigation connector 293, through irrigation supply line 255b in umbilical cord 260, and down the irrigation supply line in the endoscope shaft 100a to the distal end 100c. To balance the pressure in the water source as water is pumped out of the irrigation supply line, a vent (not shown) may be included in the top of the water reservoir. The vent allows atmospheric air into the water source, preventing the buildup of negative pressure that could create a vacuum that would draw unwanted material back from the patient through the endoscope toward the water source. In some embodiments, similar to the lens cleaning line 245c, an outflow check valve or other one-way valve configuration (not shown) may be placed in the path of the irrigation supply line to help prevent backflow into the reservoir after water has passed through the valve.

[0057] Other arrangements using these fluid sources are conceivable, depending on need. For example, in some cases, water used for irrigation and lens cleaning may come from the same container. Some illustrative systems and methods for supplying fluid to an endoscope are described in U.S. Patent Application No. 63 / 419,900, which is commonly assigned and entitled “DEVICES, SYSTEMS, AND METHODS TO SUPPLY FLUIDS TO ANENDOSCOPE”, the disclosure of which is incorporated herein by reference.

[0058] Figure 3 A schematic diagram of another illustrative endoscope system 300 is depicted, which can reduce the frequency of water reservoir replacements and / or reduce the chance of contamination during water reservoir(s) replacement. System 300 may include several advantages over the aforementioned current bottle system. System 300 may include, with regard to... Figures 1 to 2 The described endoscope system and similar components are described; however, not all features can be described or shown herein.

[0059] Typically, system 300 may include a first reservoir 302 and a second reservoir 330. The first reservoir 302 may be configured to supply water or fluid for both rinsing (e.g., via the first reservoir 302) and lens cleaning (e.g., via the second reservoir 330). This allows the use of a single fluid source to supply fluid for both rinsing and lens cleaning. Although not explicitly shown, reservoirs 302, 330 may include printed lines, numbers, or other visual markings to allow a user to easily determine how much fluid remains in reservoirs 302, 330.

[0060] The first reservoir 302 may include a first container 304 configured to contain a first volume of fluid 306. In the illustrated embodiment, the first container 304 is fluidly coupled to an upstream irrigation supply line 328 and configured to supply fluid for irrigation to the endoscope 100. Typically, the irrigation supply line 328 may be a water or fluid supply line or tube for supplying water or other fluids to the endoscope. Additionally, the first container 304 may be optionally fluidly coupled to a second fluid reservoir 330. The second reservoir 330 may include a second container 332 configured to contain a second volume of fluid 334. In the illustrated embodiment, the second container 332 is fluidly coupled to a gas supply line and lens cleaning supply lines 336, 338 and configured to supply fluid for lens cleaning to the endoscope 100. Typically, the lens cleaning supply line 338 may be a water or fluid supply line or tube for supplying water or other fluids to the endoscope. The gas supply line 336 and the lens cleaning supply line 338 may be arranged coaxially. For example, the gas supply line 336 may define a lumen with a diameter large enough to accommodate a smaller diameter lens cleaning line 338 coaxially received within the gas supply line 336, and to supply air to a water source in an annular space surrounding the lens cleaning line 338 to pressurize the second reservoir 330. The lens cleaning supply line 338 may be configured to exit the lumen defined by the coaxial gas supply line 336 with any suitable sealing method (e.g., orifice, fitting, collar, and / or similar construction) for the purpose of changing from a coaxial arrangement to a side-by-side arrangement at the detachable gas / lens cleaning connection connected to the endoscope connector portion 265. In other embodiments, the gas supply line 336 and the lens cleaning supply line 338 may be arranged side-by-side.

[0061] The first container 304 and the second container 332 may be formed of one or more lightweight, flexible materials, such as, but not limited to, low-density polyethylene (LDPE), thermoplastic polyurethane (TPU), silicone, polyethylene terephthalate (PET), aluminum, nylon, polyethylene (PE), plasticized polyvinyl chloride (PVC), or combinations thereof. In some embodiments, the first container 304 and the second container 332 may be completely translucent, completely opaque, or a combination thereof. In some cases, the first container 304 and the second container 332 may be similar to flexible bags used for delivering intravenous fluids in a clinical setting (e.g., intravenous (IV) fluid bags). Such bags may be readily available and familiar to clinicians, as they are widely used in a variety of sizes. The volume of the first container 304 and the second container 332 may be variable. For example, the volume of the first container 304 and / or the second container 332 may be 500 ml or more, 1000 mL or more, 2000 mL or more, 3000 mL, 4000 mL or more, etc. The volume may be less than 500 mL or greater than 4000 mL, depending on the need. One or both of the first reservoir 302 and the second reservoir 330 may be pre-filled with water or other fluids (e.g., before entering the operating room or at the time of manufacture). In some cases, clinicians may select reservoirs 302, 330 from a plurality of available reservoirs of different sizes based on the number and / or type of surgeries expected for a typical day or a particular day. In the illustrated embodiment, the first reservoir 302 may supply fluid to the second reservoir 330. By selecting a first reservoir 302 with a volume large enough to accommodate surgeries throughout the day, the need to replace the sterile fluid source (e.g., the first reservoir 302) can be reduced or eliminated. In some cases, the first reservoir 302 may be used to periodically refill the second reservoir 330. Therefore, the volume of the first reservoir 302 may be larger than the volume of the second reservoir 330, but this is not necessary. It is further envisioned that, in some embodiments, one or both of the first reservoir 302 or the second reservoir 330 may be a rigid bottle.

[0062] It is conceivable that flexible bags can use less plastic (or other materials) than bottles designed to hold a similar amount of fluid. Therefore, using flexible bags as fluid reservoirs 302, 330 can improve the environmental sustainability of system 300. For example, if a user sets up a 3000 mL (3 liter) bag reservoir 302 for the system and therefore does not need to use three separate one-liter bottles, a significant reduction in waste can be achieved. It is further conceivable that when disposed of or discarded, the flexible bag reservoir can occupy a smaller volume than a bottle capable of holding an equivalent volume of fluid.

[0063] The first reservoir 302 may further include one or more ports 308a, 308b, such as, but not limited to, spiked ports or diaphragm ports, which extend from the interior of the first container 304 and are in selective fluid communication with the interior of the container. Ports 308a, 308b may be integrally formed with the first container 304. Ports 308a, 308b may be generally tubular structures, wherein each port 308a, 308b defines a lumen extending therethrough. The lumen of ports 308a, 308b may be configured to selectively fluidly connect the interior of the first container 304 to another component (such as, but not limited to, a fluid or water supply pipe). In some embodiments, ports 308a, 308b may be located adjacent to the bottom end 312 of the first reservoir 302. However, this is not necessary. Ports 308a, 308b may be located at other locations as needed. If ports 308a and 308b are located outside the bottom 312 of the first container 304, a suction tube or tube extension may be required to access the fluid at the bottom of the first container 304. In some cases, at least one port 308b may be configured to connect to an upstream flushing line (or water supply line) 328, while another port 308a may be configured to allow a user to add additives to the fluid 306. In other examples, the upstream flushing line 328 may connect to the first port 308a, while the second reservoir 330 is in fluid communication with the second port 308b. Although the first reservoir 302 is shown to include two ports 308a and 308b, the first reservoir 302 may include one or more ports as needed.

[0064] Although not explicitly shown, ports 308a and 308b may each include a removable cap or seal configured to form a fluid-impermeable seal with ports 308a and 308b. The removable cap or seal helps maintain the sterility of ports 308a and 308b. The removable cap or seal can be attached to the free end of ports 308a and 308b using several different techniques. For example, the cap or seal can be attached to ports 308a and 308b using threaded engagement, friction fit, snap-fit, etc. In other instances, the cap or seal can be removed by a torsional movement configured to disconnect the cap or seal from ports 308a and 308b. Once the cap or seal has been removed, ports 308a and 308b can be pierced using a spiked tip or spiked port adapter 310 connected to the upstream flushing line 328. For example, in addition to a removable cap or seal, ports 308a and 308b may include internal seals disposed within the lumens of ports 308a and 308b, which may be punctured or penetrated by the spike port adapter 310. The internal seals may be configured to prevent fluid 306 from leaking from the first container 304 before the spike port adapter 310 is inserted into ports 308a and 308b. In some embodiments, the internal seals may be self-sealing, preventing fluid leakage from ports 308a and 308b when the spike port adapter 310 is removed. The outer surface of the spike port adapter 310 may form an interference fit with the inner surface of ports 308a and 308b. The fit and / or connection between the spike port adapter 310 and ports 308a and 308b may be sufficient to hold them in place when the flushing supply tube 328, branch connector 350, and / or other piping assemblies are connected to the spike port adapter 310. It is conceivable that the spiked port adapter 310 could be inserted into one of ports 308a and 308b using commonly used aseptic techniques (such as those used with IV fluid bags). This could help reduce the risk of infection by maintaining sterile components and preventing contaminants from being introduced into fluid 306. It is further conceivable that additives could be added to fluid 306 via one of ports 308a and 308b using similar aseptic techniques.

[0065] The first reservoir 302 may include a handle 316 positioned adjacent to its top portion 314. The handle 316 may define an opening or through-hole 318 for receiving a hand or hook to carry the first reservoir 302. In some cases, the handle 316 may include an undulating surface configured to provide a more ergonomic grip for the user. It is conceivable that the handle 316 may be formed from a material similar to or different from the first container 304, as needed. In some examples, the handle 316 may be formed from polyethylene terephthalate (PET), polypropylene (PP), etc. The handle 316 may allow the first reservoir 302 to be suspended on a hook, such as, but not limited to, an IV stand. Suspending the first reservoir 302 allows it to be positioned above the height of the endoscope cart, enabling the user to see the fluid level 306 at any time. This can help clinicians avoid fluid depletion during surgery. Additionally, raising the reservoir eliminates the need for clinicians to bend or lean forward during the setup of system 300 and / or replacement of the first reservoir 302. In some cases, the pressure head generated by raising the first reservoir 302 can enable rapid pre-charging of the irrigation circuit (and / or lens cleaning circuit, if so connected), saving time during setup. It is further conceivable that suspending the first reservoir 302 on a hook or IV stand allows it to be positioned away from expensive capital equipment, thereby reducing or eliminating the possibility of fluid inadvertently flowing onto or onto capital equipment and causing damage or destruction.

[0066] The first reservoir 302 is fluidly connected to the lumen of the upstream irrigation supply line 328. The upstream irrigation supply line 328 extends from a second end region 322 located outside the container 304 and within the pump head 324 of the peristaltic irrigation pump 315 to a first end 320. The first end 320 of the upstream irrigation supply line 328 is coupled to a spiked port adapter 310, which is further configured to extend through the lumen of port 308b and pierce a seal within the lumen of port 308b to fluidly connect the interior of the container 304 to the lumen of the upstream irrigation supply line 328. The second end of the upstream irrigation supply line 328 is configured to fluidly connect to the irrigation lumen of the endoscope 100. When flushing water is required, fluid is pumped from the first container 304 by operating the flushing pump 315 (e.g., by pressing a foot switch (not shown)), and the fluid flows from the first reservoir 302 through the upstream flushing supply line 328 and branch connector 350, through the downstream flushing supply line 255c, through the flushing connector 293, through the flushing supply line 255b in the umbilical line 260, and down along the flushing supply line 255a in the endoscope shaft 100a to the distal end 100c.

[0067] The downstream irrigation supply line 255c may include a loaded check valve or flow control valve 326 positioned in series with the downstream irrigation supply line 255c. The flow control valve 326 can prevent fluid from unintentionally flowing from the first container 304 into the endoscope 100. In some cases, the flow control valve 326 can be configured to open when the pressure in the downstream irrigation supply line 255c reaches a predetermined minimum pressure. It is conceivable that the predetermined minimum pressure may be greater than the head generated by the height difference between the first reservoir 302 and the irrigation pump 315. The flow control valve 326 can also prevent fluid leakage from the downstream irrigation supply line 255c when the endoscope 100 is changed between patients and the tubing kit connector is disconnected from the endoscope water port.

[0068] In some embodiments, the irrigation pump 315 may be omitted. For example, the reservoir 302 may be inserted into a compression sleeve. When irrigation fluid is desired, the compression sleeve can be activated to apply pressure to the outer surface of the reservoir 302 and provide the necessary pressure for performing irrigation at the distal end of the endoscope 100. In another embodiment, the reservoir 302 may be inserted into a compression sleeve that applies a constant pressure to the reservoir 302, wherein a flow switch is positioned along the irrigation supply line 328 to provide binary control of the irrigation flow.

[0069] The second reservoir 330 may further include one or more ports 340, such as, but not limited to, spiked ports or diaphragm ports, extending from the interior of the second container 332 and in selective fluid communication with the interior of the second container. Ports 340 may be integrally formed with the second container 332. Ports 340 may be generally tubular structures, wherein port 340 defines a lumen extending therethrough. The lumen of port 340 may be configured to selectively fluidly connect the interior of the second container 332 to another component (such as, but not limited to, a fluid / water / gas supply line). In some cases, port 340 may be configured to connect to a gas supply line 336 and a lens cleaning supply line 338. In some embodiments, port 340 may be positioned adjacent to the bottom end 342 of the second reservoir 330. However, this is not required. Port 340 may be positioned at other locations as needed. If port 340 is located outside the bottom 342 of the second container 332, a draw tube or tube extension (e.g., connected to the lens cleaning supply line 338) may be needed to access the fluid at the bottom of the second container 332. Although the second reservoir 330 is shown to include one port 340, the second reservoir 330 may include more than one port as needed.

[0070] Although not explicitly shown, port 340 may include a removable cap or seal configured to form a leak-proof seal with port 340. The removable cap or seal helps maintain the sterility of port 340. The removable cap or seal can be attached to the free end of port 340 using several different techniques. For example, the cap or seal can be attached to port 340 using threaded engagement, friction fit, snap-fit, etc., or it can be securely attached using several techniques such as adhesive or solvent bonding. In other instances, the cap or seal can be removed by a torsional movement configured to disconnect the cap or seal from port 340. Once the cap or seal has been removed, port 340 can be pierced with a spiked end or spiked port adapter (not explicitly shown) connected to gas supply line 336 and lens cleaning supply line 338. For example, in addition to the removable cap or seal, port 340 may include an internal seal disposed within the lumen of port 340, which can be pierced or penetrated by the spiked port adapter. An internal seal may be configured to prevent fluid 334 from leaking from the second container 332 before the spike port adapter is inserted into port 340. In some embodiments, the internal seal may be self-sealing, preventing fluid leakage from port 340 when the spike port adapter is removed. The outer surface of the spike port adapter may form an interference fit with the inner surface of port 340. The fit and / or connection between the spike port adapter and port 340 may be sufficient to hold it in place when the gas supply line 336 and fluid supply line 338 and / or other line kits are connected to the spike port adapter. It is envisioned that the spike port adapter may be inserted into port 340 using commonly used aseptic techniques, such as those used with IV fluid bags. This can help reduce the risk of infection by maintaining sterile components and preventing contaminants from being introduced into fluid 334. It is further envisioned that, if desired, additives may be added to fluid 334 via port 340 using similar aseptic techniques. In some cases, additional coupling mechanisms may be used as needed to connect the gas supply line 336 and the lens cleaning supply line 338 to the port 340. Some illustrative coupling mechanisms may include, but are not limited to, threaded engagement, snap-fit, friction engagement, quick-connect couplings, etc., or may be used to securely connect using several techniques (such as adhesive or solvent bonding).

[0071] A gas supply line 336 extends from a second end outside the second container 332 to a port 340. The gas supply line 336 may extend into the interior of the second container 332 and terminate within a reservoir gap (e.g., above the level of fluid 334). However, in some cases, the gas supply line 336 may terminate within fluid 334. A lumen extends through the gas supply line 336 to receive air and / or gas flow therethrough. The lumen of the gas supply line 336 may be in operative fluid communication with the top portion of the interior of the second container 332. A lens cleaning supply line 338 extends from a second end outside the second reservoir 330 to a first end in fluid communication with the bottom portion 342 of the second container 332. In some embodiments, the lens cleaning supply line 338 may terminate at port 340. A lumen extends through the lens cleaning supply line 338 to receive fluid flow therethrough. The lumen of the lens cleaning supply line 338 is selectively in operative fluid communication with the bottom portion 342 of the second container 332. In the illustrated embodiment, the gas supply line 336 and the lens cleaning supply line 338 can be connected to the second container 332 via a single or common opening (e.g., port 340). For example, the gas supply line 336 and the lens cleaning supply line 338 can be arranged coaxially. However, this is not required. In some cases, the gas supply line 336 and the lens cleaning supply line 338 can extend side by side, or can be connected to the second container 332 separately at different locations.

[0072] The second container 332 may further include a first fluid inlet 344 and a second fluid inlet 346. While the first fluid inlet 344 and the second fluid inlet 346 are shown adjacent to or extending from the top portion 348 of the second container 332, the first fluid inlet 344 and / or the second fluid inlet 346 may be positioned at other locations around the second container 332 as needed. In some embodiments, the first fluid inlet 344 and / or the second fluid inlet 346 may be tubular members formed as a single integral structure with the second container 332. In other embodiments, the first fluid inlet 344 and / or the second fluid inlet 346 may include tubular components releasably coupled to ports (similar in form and function to port 340) formed in or with the container 332.

[0073] The first fluid inlet 344 may be in selective fluid communication with the first reservoir 302. For example, the branch connector 350 may be positioned in series with the upstream flushing line 328. In some embodiments, the branch connector 350 may be a "Y" type connector or a "T" type connector having an inlet branch 356 defining a first fluid inlet, a first outlet branch 352 defining a first fluid outlet, and a second outlet branch 354 defining a second fluid outlet. However, it is contemplated that the branch connector 350 may include more than one fluid inlet and fewer than two or more than two fluid outlets, if so required.

[0074] Branch connector 350 can be positioned in series with upstream flushing line 328 such that inlet branch 356 and first outlet branch 352 are fluidly connected to the lumen of upstream flushing line 328. Fluid can flow from first reservoir 302 through upstream flushing line 328, through branch connector 350, and again through upstream flushing line 328. Branch connector 350 can be positioned such that inlet branch 356 is upstream of outlet branches 352, 354 relative to flushing fluid flow. In some embodiments, branch connector 350 and spike port adapter 310 can be molded or formed as a single integral structure. This is contemplated to reduce connection points in the fluid loop. In this case, first end 320 of flushing supply line 328 can be fluidly connected to first outlet branch 352 of branch connector 350.

[0075] The second outlet branch 354 may be fluidly connected to the first fluid inlet 344 of the second reservoir 330. A flow control mechanism (such as, but not limited to, a check valve 358) may be located between the second fluid outlet of the second outlet branch 354 and the first fluid inlet 344 of the second reservoir 330 to selectively connect the second container 332 to the first container 304. The check valve 358 may be configured to open to allow fluid to selectively flow from the first reservoir 302 to the second reservoir 330, while preventing fluid (e.g., gas, water, or other fluid) from leaving the second container 332 and entering the flushing supply line 328 and / or the first container 304. In some embodiments, the check valve 358 may be replaced by a clamp that can compress the first fluid inlet 344 to selectively isolate the second container 332 from the first container 304, and be removed to selectively connect the second container 332 to the first container 304. In yet other embodiments, the check valve 358 may be replaced by a spring-loaded valve, a plug valve, or other two-way valve. When it is desired to add fluid from the first reservoir 302 to the second reservoir 330, the check valve 358 (or other flow control mechanism) can be opened or released. The fluid can then be diverted at least partially from the flushing supply line 328 via the second outlet branch 354 of the branch connector 350 and enter the second container 332 along the flow path 360. Fluid can be added to the second container 332 as needed, either while the flushing pump 315 is operating or when the flushing pump 315 is idle.

[0076] The second fluid inlet (or gas supply line) 346 of the second container 332 may be an alternative gas supply line configured to connect to an alternative gas supply (e.g., a CO2 hospital ward gas source). The second fluid inlet 346 may extend from a second end outside the second container 332 to a first end connected to the second container 332. The alternative gas supply may be used to pressurize the second container 332 to supply lens cleaning water to the endoscope 100 and / or to provide gas injection. A lumen extends through the second fluid inlet 346 to receive the gas flow passing through it. The lumen of the second fluid inlet 346 is in operative fluid communication with the top portion of the second container 332. The flow of CO2 within the system 300 may be similar to the flow described above. For example, in a neutral state, CO2 gas flows into the second container 332 through the second fluid inlet 346, upward along the gas supply line 336 to the connector portion 265, upward along the gas supply line 240b in the umbilical conduit 260, and is discharged to the atmosphere through the gas / water valve 140. In the first position, the user seals the vent in the gas / water valve 140, and CO2 gas flows into the second container 332 through the second fluid inlet 346, ascends along the gas supply line 336 to the connector portion 265, flows through the gas / water valve to the gas supply line 240a in the endoscope shaft 100a, and exits the gas / lens cleaning nozzle 220 at the distal end 100c. In the second position, the user presses the valve 140 to the bottom of the valve well 135 while keeping the vent in the gas / water valve closed. The second position blocks the supply of CO2 gas to both the atmosphere and the gas supply line 240a in the endoscope 100, and opens the gas / water valve 140 to allow lens cleaning water to pass through the lens cleaning supply line 245a in the endoscope shaft 100a and exit the gas / lens cleaning nozzle 220 at the distal end 100c. The gas (pressure) in the second reservoir 330 is maintained by delivering gas via the second fluid inlet 346. It is conceivable that the one-way valve 358 is in a closed configuration during CO2 gas delivery to allow pressurization of container 332. In some instances, the one-way valve 358 may be configured to close without user intervention in response to the delivery of CO2 to the second container 332. In some embodiments, system 300 may include a branch connector (such as, but not limited to, a "Y" or "T" connector) at the second fluid inlet 346 to allow air or CO2 for pressurization or injection. It is further conceivable that the second fluid inlet 346 may include a pressure relief valve 362 (such as, but not limited to, a 3-way stopcock valve, a clamp, or a spring-loaded valve) to release pressure within the second container 332 and / or prevent pressurized gas from flowing into the second container 332 during refilling of the second container 332, during surgical transitions, and / or during device transitions.

[0077] It is conceivable that using a flexible bag instead of a rigid bottle for the second reservoir 330 could reduce or eliminate the risk of air leakage from the bottle and cap connection. This would eliminate the need for clinicians to attempt to remedy a leak by adjusting the cap and bottle assembly, or to discard the cap and / or bottle if a leak is irreparable.

[0078] Because the pressurized second reservoir 332 is fluidly isolated from the first reservoir 304 when the one-way valve 358 is closed, it is conceivable that a clinician could replace the first reservoir 302 with a new (full) reservoir without interrupting patient insufflation. Interruption of patient insufflation could lead to disruption of the positioning of the endoscope 100 within the body. In current one- or two-bottle systems, it may not be possible to replace the water reservoir without interrupting patient insufflation.

[0079] If it is necessary to replace the first reservoir 302 with a new full bag, for example when the first reservoir 302 is empty or nearly empty, the user can suspend the new bag near the first reservoir 302 to be replaced. The user can then disengage the spiked port adapter 310 from port 308b and insert the spiked port adapter 310 into the port of the new bag. This can be performed without requiring the clinician to bend or lean to access the first reservoir 302. Port 308b is self-sealing to prevent fluid leakage from the first reservoir 302 being replaced. This method of replacing the first reservoir 302 can have a lower risk of introducing contaminants into the system compared to conventional bottle systems. For example, the replacement method described herein allows the first reservoir 302 to be replaced without suspending the tubing over the cap (as is done in bottle systems). Furthermore, the system 300 can remain substantially closed while the first reservoir 302 is being replaced.

[0080] Figure 4This is a schematic perspective view of an illustrative trolley 400 that can be used to hold or mount capital equipment during endoscopic procedures. The illustrative trolley 400 may include multiple shelves 402a-e movably or permanently secured to a frame 404. The trolley 400 may include any desired number of shelves 402a-e. Shelves 402a-e may be configured to hold equipment thereon. For example, one or more processing units 210 may be positioned on one or more of the shelves 402a-e. Shelves 402a-e may include different configurations to accommodate different components of the endoscope system 200. For example, some shelves 402c-e may be generally planar to allow easy positioning and / or removal of equipment thereon. Other shelves 402a may include a raised perimeter 418 defining an internal cavity or recess 420. This helps prevent items from falling off the shelves 402a-e. In other examples, shelf 402b may include raised lips 422 along one or more of its edges to facilitate gripping of shelf 402b. Each shelf 402a-e may include an upper surface 424 on which the device may be positioned.

[0081] The trolley 400 may further include a plurality of wheels 406 to facilitate positioning of the trolley 400 within the operating room. In some cases, one or more of the wheels 406 may include a locking mechanism 408 configured to prevent movement of the wheels 406 and / or the trolley 400. One or more arms or levers 410 may extend from the frame 404. The levers 410 may be configured to mount various components thereto, such as, but not limited to, the display unit 412. In some cases, the levers 410 may include features configured to receive tube kits, endoscope handles, etc. Alternatively or additionally, mounting features 414 for receiving tube kits, endoscope handles, etc., may be mounted to one or more of the shelves 402a-e and / or the frame 404. The trolley 400 may include one or more handles, push rods, or grips 416. The levers 416 may be formed as a single integral structure with one of the shelves 402a-e or may be coupled to one of these shelves. Alternatively or additionally, the rod 416 may be formed as a single integral structure with the frame 404 or connected to the frame. It should be understood that the trolley 400 may include additional features not explicitly described herein. Furthermore, the shelves 402a-e, the frame 404, the rod 410, and / or other features may be arranged in any desired manner.

[0082] As described herein, it may be desirable to install one or more of the storage devices 302, 330 from the trolley 400 or the capital equipment positioned on the trolley, or to install one or more storage devices onto the capital equipment positioned on the trolley. Figure 5This is a front view of the illustrative shelf 402c of the trolley 400 with mounting plate 500. Mounting plate 500 can be movably positioned relative to processing unit 210 or other capital equipment configured to rest on shelves 402a-e of the trolley 400. See also... Figure 6 The figure shows a top view of an illustrative shelf 402c of a trolley 400 with a mounting plate 500. The mounting plate 500 may be a generally planar body portion 516 having a length 504 (extending from a first end 520 to a second end 522), a width 506 (extending from a first side 524 to a second side 526), ​​and a thickness 508 (extending from a top surface to a bottom surface). Although the mounting plate 500 is shown as having a generally rectangular cross-sectional shape with rounded corners (as viewed from above), the mounting plate 500 may take any desired cross-sectional shape, such as, but not limited to, square, rectangular, stadium-shaped, oblong, circular, triangular, polygonal, eccentric, etc. Mounting plate 500 can be formed from a variety of different materials, including: metallic materials, such as but not limited to aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as but not limited to acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyether ether ketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nano clay, graphene, talc, kaolin, wollastonite, etc.

[0083] Mounting plate 500 may include retaining member 502 ( Figure 6 (Not shown in the image), the retaining member can be releasably secured to or suspended from the mounting plate. Alternatively, the retaining member 502 can be formed as a single integral structure with the mounting plate 500. The retaining member 502 can be an S-hook, J-hook, timber sling hook, slip hook, safety hook, flexible rope, knot tie, hook and loop fastener, cable tie, etc. It is conceivable that the retaining member 502 can be any component configured to secure the handle 316 or fastening mechanism of the reservoir 302 to the mounting plate 500.

[0084] Mounting plate 500 may include a first opening or aperture 510 extending through its thickness 508. While the first aperture 510 is shown as having a generally rectangular cross-sectional shape with rounded corners (e.g., stadium shape), the first aperture 510 may take any desired cross-sectional shape, such as, but not limited to, circular, oblong, oval, square, rectangular, triangular, polygonal, eccentric, etc. Aperture 510 may have a length 512 extending from a first end 528 to a second end 530 and a width 514 extending from a first side 532 to a second side 534. The length 512 and width 514 of the first aperture 510 may be greater than the length and width of the legs 211 of the processing unit 210 or other capital equipment. This allows mounting plate 500 to be positioned on surface 424 of shelf 402c. Processing unit 210 or other equipment may be positioned on mounting plate 500 such that at least one leg 211 of processing unit 210 is positioned within the first aperture 510. The thickness 508 of the mounting plate 500 may be less than the height of the legs 211. It is conceivable that the mounting plate 500 can be positioned relative to any of the legs 211 of the processing unit 210 as needed. Once the reservoir 302 is suspended on the retaining member 502, the legs 211 can contact the end or edge 528 of the first opening 510 to prevent the mounting plate 500 from slipping off the shelf 402c. However, this is not necessary. It is conceivable that the weight of the processing unit 210 may be greater than the weight of the reservoir 302, such that when the reservoir 302 is suspended on the mounting plate 500, the weight of the reservoir 302 will not cause the processing unit 210 to slide along the surface 424 of the shelf 402c.

[0085] The length 512 and width 514 of the first opening 510 can be greater than the length and width of the leg 211. This allows the mounting plate 500 to be used with various types of capital equipment with legs of different sizes. It is conceivable that the length 504 of the mounting plate 500 can be selected such that when the mounting plate 500 is positioned between the processing unit 210 and the shelf 402c, and the leg 211 of the processing unit 210 is within the first opening 510, the second end 522 of the mounting plate 500 extends beyond the lateral side 426 of the shelf 402c. For example, the distance between the first end 528 of the first opening 510 and the second end 522 of the mounting plate 500 can be greater than the distance between the first side 213 of the leg 211 and the lateral side 426 of the shelf 402c. This allows the reservoir 302 to be freely suspended on the retaining member 502. In some examples, the mounting plate 500 can be oriented such that the second end 522 of the mounting plate 500 extends beyond the front or rear edge of the shelf 402c.

[0086] The second orifice 518 may extend through the thickness 508 of the mounting plate 500 adjacent to the second end 522 of the mounting plate 500. The second orifice 518 may have a generally circular cross-section. However, this is not required. The second orifice 518 may take any desired cross-sectional shape, such as, but not limited to, oblong, oval, square, rectangular, stadium-shaped, triangular, polygonal, eccentric, etc. The second orifice 518 may be configured to receive the retaining member 502. The diameter of the second orifice 518 may be determined to allow the retaining member 502 to pass through it. In some cases, the retaining member 502 may be suspended in the region of the mounting plate 500 located between the second orifice 518 and the second end 522 of the mounting plate, such as... Figure 5 As shown. In some examples, the retaining member 502 can form a ring once it is secured to the reservoir 302. However, this is not necessary.

[0087] Figure 7 This is a top view of another illustrative mounting plate 600, which can be movably positioned relative to the processing unit 210 or other capital equipment configured to rest on shelves 402a-e of the trolley 400. The mounting plate 600 may include a generally planar first body portion 602 movably coupled to a generally planar second body portion 604. The first body portion 602 may have a generally "U"-shaped or horseshoe-shaped structure including a first leg 606, a second leg 608 spaced apart from and extending generally parallel to the first leg 606, and a bridging portion 610 interconnecting the first leg 606 and the second leg 608. In some embodiments, the first leg 606 may be longer than the second leg 608. In other embodiments, the second leg 608 may be longer than the first leg 606. In other embodiments, the first leg 606 and the second leg 608 may have the same or similar lengths. The first leg 606 may be laterally spaced from the second leg 608 adjacent to its free end to define an opening or gap 618. Similarly, the second body portion 604 may have a generally U-shaped or horseshoe-shaped structure, including a first leg 612, a second leg 614 spaced apart from and extending generally parallel to the first leg 612, and a bridging portion 616 interconnecting the first leg 612 and the second leg 614. In some embodiments, the first leg 612 may be longer than the second leg 614. In other embodiments, the second leg 614 may be longer than the first leg 612. In other embodiments, the first leg 612 and the second leg 614 may have the same or similar lengths. The first leg 612 may be laterally spaced from the second leg 614 adjacent to its free end to define an opening or gap 620.

[0088] During assembly, the free end of the first leg 606 of the first body portion 602 may overlap with the free end of the first leg 612 of the second body portion 604, and the free end of the second leg 608 of the first body portion 602 may overlap with the free end of the second leg 614 of the second body portion 604. It is conceivable that in some cases, the first body portion 602 may be positioned above the second body portion 604, and in other cases, the second body portion 604 may be positioned above the first body portion 602. During assembly, the opening 618 of the first body portion 602 may be aligned with the opening 620 of the second body portion 604 to define a first aperture 622. The length 624 of the first aperture 622 may be adjustable via one or more adjustment mechanisms 626a, 626b. For example, the length 624 of the first aperture 622 may be increased or decreased to accommodate different leg sizes of the capital equipment.

[0089] In the illustrated embodiments, the adjusting mechanisms 626a, 626b may each include racks 628a, 628b extending substantially parallel to the longitudinal axis of the first aperture 622. In some embodiments, racks 628a, 628b may be positioned on the second body portion 604. However, this is not necessary. Racks 628a, 628b may be positioned on the first body portion 602 or on both the first body portion 602 and the second body portion 604 as needed. In some examples, racks 628a, 628b may extend beyond the free ends of the first legs 606, 612 and / or the second legs 608, 614 of the first body portion 602 and / or the second body portion 604. Racks 628a, 628b may include a plurality of teeth 630a, 630b, which include alternating ridges and valleys. Pawls or other locking mechanisms 632a, 632b may be positioned at the ends of racks 628a, 628b to engage teeth among the plurality of teeth 630a, 630b, thereby maintaining the first body portion 602 and the second body portion 604 in a desired configuration. In some embodiments, pawls 632a, 632b may be positioned on the first body portion 602. However, this is not necessary. Pawls 632a, 632b may be positioned on the second body portion 604 or on both the first body portion 602 and the second body portion 604 as needed. Pawls 632a, 632b and teeth 630a, 630b may be configured to allow the second body portion 604 to move toward the bridging portion 610 of the first body portion 602 while restricting movement of the second body portion 604 in the opposite direction. Alternatively, a reverse configuration can be conceived, in which pawls 632a, 632b and teeth 630a, 630b can be configured to allow the second body portion 604 to move away from the bridging portion 610 of the first body portion 602, while restricting movement of the second body portion 604 in the opposite direction. In other examples, pawls 632a, 632b and teeth 630a, 630b can be configured to allow the second body portion 604 to move toward or away from the bridging portion 610 of the first body portion 602. It is conceivable that pawls 632a, 632b can be actuated to disengage from teeth 630a, 630b, thereby allowing the second body portion 604 to move freely relative to the first body portion 602. Although the adjusting mechanisms 626a and 626b are shown as including racks 628a and 628b and pawls 632a and 632b, other adjusting mechanisms, such as, but not limited to, racks and pinions, may also be used. Although not explicitly shown, the first body portion 602 and the second body portion 604 may include features such as mating grooves and ridges to help secure the first body portion 602 and the second body portion 604 to each other.

[0090] The first opening 622 extends through the thickness of the mounting plate 600. While the first opening 622 is shown as having a generally rectangular cross-sectional shape with rounded corners (e.g., stadium shape), it can take any desired cross-sectional shape, such as, but not limited to, circular, oblong, oval, square, rectangular, triangular, polygonal, eccentric, etc. As described herein, the length of the first opening 622 can be adjustable to allow the mounting plate 600 to be used with different types of capital equipment. The mounting plate 600 can be positioned on the surface 424 of the shelf 402c. The processing unit 210 or other equipment can be positioned on the mounting plate 600 such that at least one leg 211 of the processing unit 210 is positioned within the first opening 622. It is conceivable that the mounting plate 600 can be positioned relative to any of the legs 211 of the processing unit 210 as needed. The length 624 of the first opening can be adjusted before or after positioning the legs 211 of the processing unit 210 in the first opening 622. Once the reservoir 302 is suspended on the retaining member 502, the leg 211 can contact the end or edge 638 of the first opening 622 to prevent the mounting plate 600 from slipping off the shelf 402c. However, this is not necessary. It is conceivable that the weight of the processing unit 210 can be greater than the weight of the reservoir 302, such that when the reservoir 302 is suspended on the mounting plate 600, the weight of the reservoir 302 will not cause the processing unit 210 to slide along the surface 424 of the shelf 402c.

[0091] Mounting plate 600 may have a length 634, a width 636, and a thickness. The length 634 of mounting plate 600 may vary depending on the amount of overlap between the first body portion 602 and the second body portion 604. For example, to shorten the length 634 of the first aperture 622 and mounting plate 600, the overlap between the first body portion 602 and the second body portion 604 may be increased, and to lengthen the length 634 of the first aperture 622 and mounting plate 600, the overlap between the first body portion 602 and the second body portion 604 may be decreased. Although mounting plate 600 is shown as having a generally rectangular cross-sectional shape with rounded edges (as viewed from top), mounting plate 600 may take any desired cross-sectional shape, such as, but not limited to, square, rectangular, stadium-shaped, oblong, circular, triangular, polygonal, eccentric, etc. Mounting plate 600 can be formed from various materials, including: metallic materials, such as but not limited to aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as but not limited to acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyether ether ketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nano clay, graphene, talc, kaolin, wollastonite, etc.

[0092] Mounting plate 600 may include a retention member (not explicitly shown) that is releasably secured to or suspended from the mounting plate. Alternatively, the retention member may be formed as a single integral structure with mounting plate 600. The retention member may be similar in form and function to the aforementioned Figure 5 The described retaining member 502. For example, the retaining member can be an S-hook, J-hook, log tying hook, slip hook, safety hook, flexible rope, knot tie, hook and loop fastener, cable tie, etc. It is conceivable that the retaining member can be any component configured to secure the handle 316 or fastening mechanism of the reservoir 302 to the mounting plate 600.

[0093] The second orifice 644 may extend through the thickness of the mounting plate 600 adjacent to the second end 642 of the mounting plate 600. The second orifice 644 may have a generally circular cross-section. However, this is not required. The second orifice 644 may take any desired cross-sectional shape, such as, but not limited to, oblong, oval, square, rectangular, stadium-shaped, triangular, polygonal, eccentric, etc. The second orifice 644 may be configured to receive a retaining member. The diameter of the second orifice 644 may be determined to allow the retaining member to pass through it. In some cases, the retaining member may be suspended in the region of the mounting plate 600 between the second orifice 644 and the second end 642 of the mounting plate. In some examples, once the retaining member is secured to the reservoir 302, the retaining member may form a ring. However, this is not required.

[0094] The width 640 of the first opening 622 can be greater than the width of the leg 211. This allows the mounting plate 600 to be used with various types of capital equipment with legs of different sizes. It is conceivable that the length 624 of the mounting plate 600 can be selected such that when the mounting plate 600 is positioned between the processing unit 210 and the shelf 402c and the leg 211 of the processing unit 210 is within the first opening 622, the second end 642 of the mounting plate 600 extends beyond the lateral side 426 of the shelf 402c. For example, when the adjusting mechanisms 626a, 626b are in their shortest configuration, the distance between the first end 638 of the first opening 622 and the second end 642 of the mounting plate 600 can be greater than the first side 213 of the leg 211 (see, for example...). Figure 6 The distance between the mounting plate 600 and the lateral side 426 of the shelf 402c. In other words, when the length 634 of the mounting plate 600 is minimized or in its shortened configuration, the second end 642 of the mounting plate 600 extends beyond the lateral side 426 of the shelf 402c. This allows the reservoir 302 to be freely suspended on the retaining member. In some examples, the mounting plate 600 may be oriented such that the second end 642 of the mounting plate 600 extends beyond the front or rear edge of the shelf 402c.

[0095] Figure 8This is a top view of an illustrative shelf 402c of a trolley 400 with another illustrative mounting plate 700, which can be movably positioned relative to the processing unit 210 or other capital equipment configured to rest on shelves 402a-e of the trolley 400. The mounting plate 700 may include a generally planar first body portion 702 and a generally planar second body portion 704. The length of the second body portion 704 may extend generally orthogonally to the width of the first body portion 702, forming a generally "T" shape. However, the second body portion 704 may extend from the first body portion 702 at a non-orthogonal angle as needed. In some examples, the first body portion 702 and the second body portion 704 may be formed as a single integral structure. In other examples, the first body portion 702 and the second body portion 704 may be formed as separate components that are subsequently joined together.

[0096] The first body portion 702 may have a width 706 extending from a first lateral side 708 to a second lateral side 710, a length 712 extending from a first end 714 to a second end 716, and a thickness (not explicitly shown). The second body portion 704 may have a width 718 extending from a first lateral side 720 to a second lateral side 722, a length 724 extending from a first end 726 to a second end 728, and a thickness. The second body portion 704 may be positioned between the first lateral side 708 and the second lateral side 710 of the first body portion 702. In some examples, the second body portion 704 may extend from approximately a central location between the first lateral side 708 and the second lateral side 710 of the first body portion 702. However, this is not necessary. In some examples, the mounting plate 700 may be positioned such that the second body portion 704 extends between two adjacent legs 211.

[0097] It is conceivable that the width 706 of the first body portion 702 may be greater than the width 718 of the second body portion 704. For example, the width 706 of the first body portion 702 may be greater than the distance 730 between adjacent legs 211 of the processing unit (or other capital equipment), while the width 718 of the second body portion 704 may be less than the distance 730 between adjacent legs 211. In some embodiments, the width 706 of the first body portion 702 may be greater than the width of the processing unit 210, but this is not necessary.

[0098] It is conceivable that the width 706 of the first body portion 702 can be selected such that when the reservoir 302 is suspended adjacent to the second end portion 728 of the second body portion 704, the second end portion 716 of the first body portion 702 can contact the edge 213 of the leg 211. Although the mounting plate 700 is shown positioned such that the second end portion 728 of the second body portion 704 extends beyond the lateral side 426 of the shelf 402c, it is conceivable that the size and shape of the mounting plate 700 can be determined as needed such that the second end portion 728 of the second body portion 704 extends beyond the front or rear edge of the shelf 402c.

[0099] Although the first body portion 702 and the second body portion 704 are shown as having a generally rectangular cross-sectional shape with rounded corners (as viewed from above), the first body portion 702 and the second body portion 704 can take any desired cross-sectional shape, such as, but not limited to, square, rectangular, oblong, circular, triangular, polygonal, eccentric, etc. The mounting plate 700 can be formed from a variety of different materials, including: metallic materials, such as, but not limited to, aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as, but not limited to, acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyetheretherketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nanoclay, graphene, talc, kaolin, wollastonite, etc.

[0100] Mounting plate 700 may include a retention member (not explicitly shown) that is releasably secured to or suspended from the mounting plate. Alternatively, the retention member may be formed as a single integral structure with mounting plate 700. The retention member may be similar in form and function to the aforementioned Figure 5 The described retaining member 502. For example, the retaining member can be an S-hook, J-hook, log tying hook, slip hook, safety hook, flexible rope, knot tie, hook and loop fastener, cable tie, etc. It is conceivable that the retaining member can be any component configured to secure the handle 316 or fastening mechanism of the reservoir 302 to the mounting plate 700.

[0101] The orifice 732 may extend through the thickness of the mounting plate 700 adjacent to the second end 728 of the mounting plate 700. The orifice 732 may have a generally circular cross-section. However, this is not required. The orifice 732 may take any desired cross-sectional shape, such as, but not limited to, oblong, oval, square, rectangular, stadium-shaped, triangular, polygonal, eccentric, etc. The orifice 732 may be configured to receive a retaining member. The diameter of the orifice 732 may be determined to allow the retaining member to pass through it. In some cases, the retaining member may be suspended in the region of the mounting plate 700 between the orifice 732 and the second end 728 of the mounting plate. In some examples, once the retaining member is secured to the reservoir 302, the retaining member may form a ring. However, this is not required.

[0102] As described herein, the width 706 of the first body portion 702 of the mounting plate 700 can be greater than the distance 730 between adjacent legs 211. This allows the mounting plate 700 to be used with various types of capital equipment with legs having different spacings. It is conceivable that the length 724 of the second body portion 704 of the mounting plate 700 can be selected such that when the mounting plate 700 is positioned between the processing unit 210 and the shelf 402c and the second end 716 of the first body portion 702 rests against the adjacent leg 211 of the processing unit 210, the second end 728 of the mounting plate 700 extends beyond the lateral side 426 of the shelf 402c. This allows the reservoir 302 to be freely suspended on the retaining member. The thickness of the mounting plate 700 can be less than the height of the legs 211, such that the mounting plate 700 rests between the upper surface of the shelf 402c and the lower surface of the processing unit 210. Once the reservoir 302 is suspended on the retaining member 502, the leg 211 can contact the second end 716 of the first body portion 702 to prevent the mounting plate 700 from slipping off the shelf 402c. However, this is not necessary. It is conceivable that the weight of the processing unit 210 can be greater than the weight of the reservoir 302, such that when the reservoir 302 is suspended on the mounting plate 700, the weight of the reservoir 302 will not cause the processing unit 210 to slide along the surface 424 of the shelf 402c.

[0103] Figure 9This is a top view of an illustrative shelf 402c of a trolley 400 with another illustrative mounting plate 800, which can be movably positioned relative to the processing unit 210 or other capital equipment configured to rest on shelves 402a-e of the trolley 400. The mounting plate 800 may include a generally planar body portion 802. The body portion 802 may have a length 804 extending from a first end 806 to a second end 808, a width 810 extending from a first lateral side 812 to a second lateral side 814, and a thickness (not explicitly shown). The width 810 of the body portion 802 may be greater than the distance 816 between adjacent legs 211 of the processing unit (or other capital equipment). In some embodiments, the width 810 of the body portion 802 may be greater than the width of the processing unit 210, but this is not required. It is contemplated that the width 810 of the body portion 802 may allow adjacent legs 211 of the processing unit 210 to rest on the upper surface 818 of the body portion 802. For example, mounting plate 800 can be positioned between the upper surface of shelf 402c and the bottom surface of one or more legs 211 of processing unit 210. It is conceivable that mounting plate 800 can be used with capital equipment that does not include legs. In this case, mounting plate 800 can be positioned between the upper surface of shelf 402c and the bottom surface of capital equipment.

[0104] It is conceivable that the width 810 of the body portion 802 can be selected such that when the reservoir 302 is suspended adjacent to the second end 808 of the body portion, the weight of the processing unit 210 will hold the mounting plate 800 in the desired position. In other words, the processing unit 210 is positioned on top of the mounting plate 800 in such a way that when the weight of the reservoir 302 is suspended adjacent to the second end 808 of the mounting plate, it prevents the mounting plate 800 from sliding or moving. Although the mounting plate 800 is shown positioned such that the second end 808 of the body portion 802 extends beyond the lateral side 426 of the shelf 402c, it is conceivable that the size and shape of the mounting plate 800 can be determined as needed such that the second end 808 of the body portion 802 extends beyond the front or rear edge of the shelf 402c.

[0105] Although mounting plate 800 is shown as having a generally rectangular cross-sectional shape with rounded corners (as viewed from above), mounting plate 800 can take any desired cross-sectional shape, such as, but not limited to, square, rectangular, stadium-shaped, oblong, circular, triangular, polygonal, eccentric, etc. Mounting plate 800 can be formed from a variety of different materials, including: metallic materials, such as, but not limited to, aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as, but not limited to, acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyetheretherketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nanoclay, graphene, talc, kaolin, wollastonite, etc.

[0106] Mounting plate 800 may include a retention member (not explicitly shown) that is releasably secured to or suspended from the mounting plate. Alternatively, the retention member may be formed as a single integral structure with mounting plate 800. The retention member may be similar in form and function to the aforementioned Figure 5 The described retaining member 502. For example, the retaining member can be an S-hook, J-hook, log tying hook, slip hook, safety hook, flexible rope, knot tie, hook and loop fastener, cable tie, etc. It is conceivable that the retaining member can be any component configured to secure the handle 316 or fastening mechanism of the reservoir 302 to the mounting plate 800.

[0107] The orifice 820 may extend through the thickness of the mounting plate 800 adjacent to the second end 808 of the mounting plate 800. The orifice 820 may have a generally circular cross-section. However, this is not required. The orifice 820 may take any desired cross-sectional shape, such as, but not limited to, oblong, oval, square, rectangular, stadium-shaped, triangular, polygonal, eccentric, etc. The orifice 820 may be configured to receive a retaining member. The diameter of the orifice 820 may be determined to allow the retaining member to pass through it. In some cases, the retaining member may be suspended in the region of the mounting plate 800 between the orifice 820 and the second end 808 of the mounting plate. In some examples, once the retaining member is secured to the reservoir 302, the retaining member may form a ring. However, this is not required.

[0108] As described herein, the width 810 of the body portion 802 of the mounting plate 800 can be greater than the distance 816 between adjacent legs 211. This allows the mounting plate 800 to be used with various types of capital equipment with legs having different spacings. It is conceivable that the length 804 of the mounting plate 800 can be selected such that when the mounting plate 800 is positioned between the processing unit 210 and the shelf 402c, and at least a portion of the body portion 802 rests below the adjacent legs 211 of the processing unit 210 (or below the capital equipment), the second end 808 of the mounting plate 800 extends beyond the lateral side 426 of the shelf 402c. This allows the reservoir 302 to be freely suspended on the retaining member. The thickness of the mounting plate 800 can be selected such that when the processing unit 210 rests on the mounting plate 800, the tilt of the processing unit 210 does not affect the function of the system or its safety when placed on the trolley 400. It is conceivable that the weight of the processing unit 210 can be greater than the weight of the storage unit 302, so that when the storage unit 302 is suspended on the mounting plate 800, the weight of the storage unit 302 will not cause the mounting plate 800 and therefore the processing unit 210 to slide along the surface 424 of the shelf 402c.

[0109] Figure 10 This is a top view of an illustrative shelf 402c of a trolley 400 with another illustrative mounting plate 900, which can be movably positioned relative to the processing unit 210 or other capital equipment configured to rest on shelves 402a-e of the trolley 400. The mounting plate 900 may include a generally planar body portion 902. The body portion 902 may have a length 904 extending from a first end 906 to a second end 908, a width 910 extending from a first lateral side 912 to a second lateral side 914, and a thickness (not explicitly shown). The mounting plate 900 can be configured for use with a legless processing unit 210 or other capital equipment. Therefore, the length 904 and / or width 910 of the body portion 902 may be greater than the length and / or width of the processing unit 210 (or other capital equipment) to minimize swaying or tilting when pressure is applied to the edges of the processing unit 210. However, this is not necessary. In some examples, the length 904 and / or width 910 of the body portion 902 may be smaller than the length and / or width of the processing unit 210 (or other capital equipment). It is further envisioned that the mounting plate 900 can be used with the processing unit 210 (or other capital equipment) including legs. It is envisioned that the length 904 and / or width 910 of the body portion 902 may allow the processing unit 210 to be rested on the upper surface 916 of the body portion 902. For example, the mounting plate 900 may be positioned between the upper surface of the shelf 402c and the bottom surface of the processing unit 210.

[0110] It is conceivable that the length 904 and / or width 910 of the body portion 902 can be selected such that when the reservoir 302 is suspended adjacent to the second end 908 of the body portion, the weight of the processing unit 210 will hold the mounting plate 900 in the desired position. In other words, the processing unit 210 is positioned on top of the mounting plate 900 in such a way that when the weight of the reservoir 302 is suspended adjacent to the second end 908 of the mounting plate, it prevents the mounting plate 900 from sliding or moving. Although the mounting plate 900 is shown positioned such that the second end 908 of the body portion 902 extends beyond the lateral side 426 of the shelf 402c, it is conceivable that the size and shape of the mounting plate 900 can be determined as needed such that the second end 908 of the body portion 902 extends beyond the front or rear edge of the shelf 402c.

[0111] Although mounting plate 900 is shown as having a generally rectangular cross-sectional shape with rounded corners (as viewed from above), mounting plate 900 can take any desired cross-sectional shape, such as, but not limited to, square, rectangular, stadium-shaped, oblong, circular, triangular, polygonal, eccentric, etc. Mounting plate 900 can be formed from a variety of different materials, including: metallic materials, such as, but not limited to, aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as, but not limited to, acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyetheretherketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nanoclay, graphene, talc, kaolin, wollastonite, etc.

[0112] Mounting plate 900 may include a retention member (not explicitly shown) that is releasably secured to or suspended from the mounting plate. Alternatively, the retention member may be formed as a single integral structure with mounting plate 900. The retention member may be similar in form and function to the aforementioned Figure 5 The described retaining member 502. For example, the retaining member can be an S-hook, J-hook, log hook, slip hook, safety hook, flexible rope, knot tie, hook and loop fastener, cable tie, etc. It is conceivable that the retaining member can be any component configured to secure the handle 316 or fastening mechanism of the reservoir 302 to the mounting plate 900.

[0113] The orifice 918 may extend through the thickness of the mounting plate 900 adjacent to the second end 908 of the mounting plate 900. The orifice 918 may have a generally circular cross-section. However, this is not required. The orifice 918 may take any desired cross-sectional shape, such as, but not limited to, oblong, oval, square, rectangular, stadium-shaped, triangular, polygonal, eccentric, etc. The orifice 918 may be configured to receive a retaining member. The diameter of the orifice 918 may be determined to allow the retaining member to pass through it. In some cases, the retaining member may be suspended in the region of the mounting plate 900 between the orifice 918 and the second end 908 of the mounting plate. In some examples, once the retaining member is secured to the reservoir 302, the retaining member may form a ring. However, this is not required.

[0114] As described herein, the length 904 and / or width 910 of the body portion 902 of the mounting plate 900 may be greater than the length and / or width of the processing unit 210. This allows the mounting plate 900 to be used with various types of capital equipment of different sizes. It is contemplated that the length 904 of the mounting plate 900 may be selected such that when the mounting plate 900 is positioned between the processing unit 210 and the shelf 402c and at least a portion of the body portion 902 rests below at least a portion of the processing unit 210 (or below the capital equipment), the second end 908 of the mounting plate 900 extends beyond the lateral side 426 of the shelf 402c. This allows the reservoir 302 to be freely suspended on the retaining member. It is contemplated that the weight of the processing unit 210 may be greater than the weight of the reservoir 302 such that when the reservoir 302 is suspended on the mounting plate 900, the weight of the reservoir 302 will not cause the mounting plate 900 to slide along the surface 424 of the shelf 402c.

[0115] As will be understood, the lengths of the irrigation tubing, lens cleaning tubing, gas supply tubing, and alternative gas supply tubing can have any suitable dimensions (e.g., diameter).

In one non-limiting embodiment, the irrigation supply tubing can have an inner diameter of approximately 6.5 mm and an outer diameter of 9.7 mm. The lens cleaning supply tubing can have an inner diameter of approximately 5 mm and an outer diameter of 8 mm. The gas supply tubing can have an inner diameter of approximately 2 mm and an outer diameter of 3.5 mm. The alternative gas supply tubing can have an inner diameter of approximately 5 mm and an outer diameter of 8 mm.
