[0002] This application claims the benefit and priority of U.S. Provisional Patent Application Serial No. 63 / 597,481, filed November 9, 2023, the disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure relates to fluid management systems. More specifically, this disclosure relates to disposable fluid cartridges and related methods for installing and removing disposable fluid cartridges from a fluid management system pump control console. Background Technology

[0004] Flexible ureteroscopy (fURS), gynecological, and other endoscopic procedures require fluid circulation for various reasons. A fluid management system can be used to deliver fluid from a reservoir to the anatomical site at the desired pressure and / or flow rate via a peristaltic or roller pump. The fluid management system can adjust the flow rate and / or pressure of the fluid delivered from the reservoir based on data collected from the procedure device, such as, but not limited to, pressure readings sensed and / or obtained by the fluid management system. The fluid management system can utilize a disposable fluid tubing kit with a pump control console to deliver fluid to the patient. There is a ongoing need to provide alternative configurations of the fluid management system's components for ease of use. Summary of the Invention

[0042] While this disclosure is adaptable to various modifications and alternatives, 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 this disclosure is not intended to limit it to the specific embodiments described. Rather, the invention covers all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure. Detailed Implementation

[0043] The terms defined below shall apply unless otherwise specified in the claims or elsewhere in this specification.

[0044] All numerical assumptions made herein are modified by the term "approximately," whether explicitly stated or not. The term "approximately" generally refers to a range of numbers that a person skilled in the art would consider equivalent to the stated value (i.e., having the same function or result). In many cases, the term "approximately" may include numbers rounded to the nearest significant figure.

[0045] The numerical range represented by the endpoints includes all numbers within that range (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0046] As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural indicators unless expressly stated otherwise in the context. As used in this specification and the appended claims, the term “or” is generally used to mean “and / or” unless the context clearly indicates otherwise.

[0047] It should be noted that references to "embodiments," "some embodiments," "other embodiments," etc., in the specification indicate that the described embodiments may include one or more specific features, structures, and / or characteristics. However, such descriptions do not necessarily imply that all embodiments include the specific features, structures, and / or characteristics. Furthermore, when a specific feature, structure, and / or characteristic is described in connection with an embodiment, it should be understood that, unless explicitly stated to the contrary, these features, structures, and / or characteristics may also be used in conjunction with other embodiments, whether explicitly described or not.

[0048] The following detailed description should be read with reference to the accompanying drawings, in which similar structures in different drawings are numbered the same. The drawings (not necessarily to scale) depict illustrative embodiments and are not intended to limit the scope of this disclosure.

[0049] For flexible ureteroscopy (fURS) procedures (e.g., ureteroscopy, percutaneous nephrolithotomy (PCNL), benign prostatic hyperplasia (BPH), transurethral resection of the prostate (TURP), etc.), some fluid management systems for gynecological and other endoscopic procedures may use inflow and / or outflow pumps of the fluid management system to control fluid inflow into body cavities and / or regulate body cavity pressure and / or fluid flow rate into body cavities. The inflow pump may deliver fluid to the patient through the inflow fitting of a fluid fitting kit, and / or the outflow pump may remove fluid from the patient through the outflow fitting of a fluid fitting kit. The fluid management system may include one or more sensors that signal the controller of the fluid management system to control fluid flow.

[0050] In fluid management systems and endoscopic devices (e.g., but not limited to LithoVue) ® In some cases where the Elite endoscope is used in conjunction with other endoscopes, the fluid management system can use pressure and / or temperature data from the endoscope or other endoscopic devices to control fluid flow. Using pressure sensors on the endoscope during medical procedures to directly regulate intracavitary pressure allows the fluid management system to safely control fluid pressure within body cavities.

[0051] Figure 1 This is a schematic diagram of a fluid management system 10, which can be used in endoscopic procedures, such as the fURS procedure. The fluid management system 10 can be coupled to a medical device (not shown) that allows fluid flow, such as an endoscope. As mentioned above, in some cases, the endoscope may include a pressure sensor, such as a LithoVue. ® Elite endoscopes or other endoscopes. In some cases, the endoscope may include a temperature sensor that provides intracavitary temperature feedback to the fluid management system 10, a pressure sensor that provides intracavitary pressure feedback to the fluid management system 10, and / or a camera that provides visual feedback to the fluid management system 10.

[0052] The fluid management system 10 also includes a fluid management unit or console 20, which includes a controller 30 housed within a housing 22 of the console 20. In some cases, the console 20 may be portable and / or movable, allowing it to be moved as needed. For example, the console 20 may be mounted on a wheeled cart 24. The wheeled cart 24 may include a rod 26 extending upward from a base 28. The base 28 may include multiple wheels 29 (e.g., casters) allowing the cart 24 to be rolled to a desired location. In other cases, the console 20 may be equipped with another type of cart, configured to be positioned on a flat surface, mounted to a wall, etc.

[0053] The fluid management system 10 may also include one or more user interface components, such as a touchscreen interface 42. The touchscreen interface 42 includes a display screen 44 and may include switches or knobs in addition to touch capabilities. In some embodiments, the controller 30 may include the touchscreen interface 42 and / or the display screen 44. The touchscreen interface 42 allows the user to input / adjust various functions of the fluid management system 10, such as flow rate, pressure, and / or temperature. The user can also configure parameters and alarms (e.g., but not limited to, a maximum pressure alarm), information to be displayed, and program modes. The touchscreen interface 42 allows the user to add, change, and / or pause the use of various modular systems within the fluid management system 10. The touchscreen interface 42 can also be used to switch between automatic and manual modes of various programs within the fluid management system 10. It is conceivable that other systems configured to receive user input could be used in place of or as a supplement to the touchscreen interface 42, such as, but not limited to, voice commands.

[0054] As will be understood by those skilled in the art, the touchscreen interface 42 may be configured to include selectable areas similar to buttons and / or provide functionality similar to physical buttons. The display screen 44 may be configured to display icons related to the modular systems and devices included in the fluid management system 10. The display screen 44 may also include a fluid flow rate and / or fluid pressure display. In some embodiments, operating parameters can be adjusted by touching corresponding portions of the touchscreen interface 42. If parameters (e.g., flow rate, temperature, etc.) are higher or lower than predetermined thresholds and / or ranges, the touchscreen interface 42 may also display visual and / or audible alarms. In some embodiments, the fluid management system 10 may also include additional user interface components, such as an optional foot pedal, a fluid heater user interface, a fluid control interface, or other means for manually controlling various modular systems. For example, an optional foot pedal may be used to manually control the flow rate. Some illustrative displays of the display screen 44 and other user interface components are described in commonly assigned U.S. Patent Application Publication No. 2018 / 0361055 entitled “AUTOMATED FLUID MANAGEMENT SYSTEM,” the entire disclosure of which is incorporated herein by reference.

[0055] The touchscreen interface 42 can be operatively connected to or part of the controller 30. The controller 30 can be a CPU, including a computer, tablet computer, or other processing device. The controller 30 can be operatively connected to one or more system components, such as an inflow pump, a fluid heating system, and a fluid deficiency management system. In some embodiments, these features can be integrated into a single unit. The controller 30 is capable of and configured to perform various functions, such as calculation, control, arithmetic, and display. The controller 30 is also capable of tracking and storing data related to the operation of the fluid management system 10 and each of its components. In some embodiments, the controller 30 includes wired and / or wireless network communication capabilities, such as Ethernet or Wi-Fi, and can be connected to, for example, a local area network (LAN). The controller 30 can also receive signals from one or more sensors of the fluid management system 10. In some embodiments, the controller 30 can communicate with a database to obtain best practice recommendations and maintain patient records that can be displayed to the user on the display screen 44.

[0056] The fluid flow rate or pressure of the fluid supplied by the fluid management system 10 at any given time can be displayed on the display screen 44 to allow the operating room (OR) to see any changes. If OR personnel notice that the fluid flow rate or pressure is too high or too low, the user can manually adjust the fluid flow rate or pressure back to the preferred level. The fluid management system 10 can also monitor and automatically adjust the fluid flow rate or pressure based on previously set parameters, as described herein.

[0057] An exemplary fluid management unit may include one or more fluid container supports, such as fluid supply source hangers 32, each of which may support a fluid supply source (e.g., a fluid bag). In some embodiments, the position and / or weight of the fluid supply source suspended from the fluid supply source hanger 32 may be detected using remote sensors and / or supply load elements associated with and / or operatively coupled to each fluid supply source hanger 32 and / or fluid container support. A controller 30 may be electrically connected to the supply load element. The fluid supply source hanger 32 may be configured to receive a first fluid supply source of various sizes, such as a 1-liter (L) to 5-L fluid bag (e.g., a saline bag). It should be understood that any number of fluid supply sources may be used. The fluid supply source hanger 32 may extend from the housing 22 of the console 20 and may include one or more hooks on which one or more fluid supply sources may be suspended. In some embodiments, the fluid used in the fluid management unit may be 0.9% saline. However, it should be understood that, depending on the procedure, various other fluids of different viscosities, concentrations, mixtures, and / or consistencies may be used.

[0058] In some embodiments, the fluid management unit may include one or more collection containers (not shown) for collecting waste fluid during medical procedures. The collection containers (e.g., storage tanks) may be in fluid communication with a vacuum pump to provide suction to draw fluid into the collection containers. The vacuum pump may be operatively and / or electronically connected to the controller 30. In some embodiments, the vacuum pump may be located within the fluid management system 10. Other configurations are also contemplated. In some embodiments, the collection containers may be operatively coupled to a collection load element to detect the position and / or weight of fluid in the collection containers, thereby aiding in fluid deficiency calculations.

[0059] The console 20 may include a door 50 hingedly attached to the housing 22 of the console 20. For example... Figure 2 As shown, door 50 can be opened to access receiving section 52, which is configured to receive the fluid cartridge 110 of the disposable fluid fitting kit 100 therein. The fluid management system 10 may include an inflow pump 60 configured to operatively engage the fluid fitting kit 100 to pump and / or transfer fluid from a fluid supply source (e.g., a fluid bag, etc.) through the fluid fitting kit 100 to a treatment site during a medical procedure. For example, the inflow pump 60 may be a roller pump or peristaltic pump positioned in receiving section 52, configured to engage a length of flexible pump tubing 106 of the fluid cartridge 110 when inserted into the fluid cartridge. Door 50 may include an obstruction bed 54 mounted on the inner surface of door 50. The obstruction bed 54 is configured to engage a length of flexible pump tubing 106 of the fluid cartridge 110 when door 50 is closed, compressing a length of flexible pump tubing 106 between the obstruction bed 54 and the inflow pump 60. The blockage bed 54 may include a concave surface configured to engage a length of flexible pump tubing 106 that extends in an arcuate path around the inflow pump 60.

[0060] The inflow pump 60 may be electrically driven and may receive power from a power source such as a wall socket, an external or internal electrical storage device such as a disposable or rechargeable battery, and / or an internal power supply. The inflow pump 60 may operate at any desired rate sufficient to deliver fluid at a desired pressure (e.g., 5 mmHg to 50 mmHg) and / or at a target fluid flow rate or target fluid pressure. As described herein, the inflow pump 60 may be automatically adjusted based on, for example, pressure and / or temperature readings within the treatment site and / or visual feedback from a medical device attached thereto and inserted into the treatment site. In some embodiments, the controller 30 may be configured to control the inflow pump 60 based on a set of system operating parameters to maintain a target fluid flow rate or target fluid pressure. In some embodiments, the controller 30 may be configured to control the inflow pump 60 based on a set of system operating parameters to maintain a desired fluid pressure or desired flow rate at the treatment site.

[0061] The inflow pump 60 can also be manually adjusted via, for example, an optional foot pedal, a touchscreen interface 42, voice commands, or a separate fluid controller. Although not explicitly shown, the fluid controller could be a separate user interface, including buttons that allow the user to raise or lower the inflow pump 60. Alternatively, the fluid controller could be integrated into the controller 30 and receive input via the touchscreen interface 42, voice commands, or other input methods. It should be understood that any number of pumps can be used. In some embodiments, the fluid management system 10 may include multiple pumps with different flow capabilities. In some embodiments, a flow meter may be located before and / or after the inflow pump 60.

[0062] The fluid management system 10 can be selected by the user between different modes based on procedures, patient characteristics, etc. For example, different modes may include, but are not limited to, fURS mode, BPH mode, hysteroscopy mode, cystoscopy mode, etc. Once the user selects a mode, mode parameters such as fluid flow rate, fluid pressure, fluid deficit, and temperature can be provided to the user via a display screen. Exemplary parameters for a specific mode can be predetermined and loaded onto the controller 30, for example, using software. Therefore, when the user selects a procedure from the initial display on the touchscreen interface display 44, these known parameters can be loaded from the controller 30 onto the various components of the fluid management system 10. The fluid management system 10 can also be selected by the user between automatic and manual modes. For example, for some procedures, the user may wish to manually adjust the fluid flow rate, fluid pressure, and / or other parameters. Once the user selects manual mode, for example, on the touchscreen interface 42, the user can adjust the fluid flow rate or fluid pressure via other manual interfaces, such as optional foot pedals, voice commands, or fluid control interfaces. If the user selects automatic mode, the user can be prompted to select or enter the medical device being used (e.g., endoscope) via touchscreen interface 42, allowing controller 30 to determine whether the data obtained from the medical device can be used to facilitate the control of fluid management system 10. In some embodiments, fluid management system 10 can be configured to verify that the selected medical device (e.g., endoscope) is actually being used before using the collected data.

[0063] The disposable tubing kit 100 may include an inflow fitting 102 that provides fluid inflow from a fluid supply source to the interior of the fluid cartridge 110. In some cases, the fluid inflow fitting 102 may include a branched fitting having a first fitting section fluidly connected to a first fluid supply source and a second fitting section fluidly connected to a second fluid supply source. The first and second fitting sections may converge (e.g., at a Y-fitting) to a common fitting section extending into the fluid cartridge 110. The ends of the first and / or second fitting sections may include a pouch needle or other connectors for connection to a fluid supply source. The disposable tubing kit 100 may also include an outflow fitting 104 that drains fluid from the interior of the cartridge 110 to a connected medical device. The disposable tubing kit 100, including the fluid cartridge 110, the fluid inflow fitting 102, and the fluid outflow fitting 104, may be disposable and provided in a sterile and ready-to-use state.

[0064] When the fluid cartridge 110 is installed in the receiving section 52 and the door 50 is closed, the inlet fitting 102 can pass through the channel 62 to reach the outside of the console 20, which extends through the wall of the housing 22 of the console 20. Similarly, when the fluid cartridge 110 is installed in the receiving section 52 and the door 50 is closed, the outlet fitting 104 can pass through the channel 64 to reach the outside of the console 20, which extends through the wall of the housing 22 of the console. Both channels 62 and 64 can extend from the outside of the console 20 to the receiving section 52. In some cases, channels 62 and 64 can be located on the same side wall of the console 20, such that the inlet fitting 102 and the outlet fitting 104 extend from the console 20 on the same side of the console 20.

[0065] In some embodiments, the fluid management system 10 may include a fluid heating system 80, such as Figure 2 The fluid heating system 80 is shown in more detail below, used to heat the fluid to be delivered to the patient. In some cases, the fluid heating system 80 may be an induction heating system. In other cases, the fluid heating system 80 may be an infrared fluid heating system. Other fluid heating system configurations and methods may also be used as needed. For example, the fluid heating system 80 may include one or more heat sources, such as a pressure plate system or in-line coil in the fluid supply line, to heat the fluid using electrical energy. Fluid heating can be specifically designed and customized according to the flow rate required in the specific application of the fluid management system 10. Some illustrative fluid heating systems are described in commonly assigned U.S. Patent Application Publication No. 2018 / 0361055 entitled “AUTOMATED FLUID MANAGEMENT SYSTEM,” the entire disclosure of which is incorporated herein by reference.

[0066] The fluid heating system 80 may include a heater configured to interact with the fluid cartridge 110 to heat the fluid passing through it. When the fluid cartridge 110 is coupled to the heater, a sensor located in the fluid path of the cartridge 110 may be positioned within an induction coil of the fluid heating system 80 and configured to heat the fluid flowing through or through the sensor as the fluid flows through the fluid flow path of the cartridge 110.

[0067] Although not explicitly shown, the fluid heating system 80 may include a heater user interface, which may be included in or separate from the touchscreen interface 42. In one example, the heater user interface may simply be a display screen that provides a digital display of the temperature of the fluid entering and / or leaving the sensor in the fluid flow path of the cartridge 110. In another embodiment, the user interface may also include temperature adjustment buttons to increase or decrease the temperature of the fluid leaving the cartridge 110. In this embodiment, the heater user interface and / or display screen may indicate the current temperature of the fluid leaving the cartridge 110 and the target temperature to be achieved. Note that all information output from the fluid heating system 80 may be directly transmitted to the display screen 44, making a heater user interface unnecessary.

[0068] The fluid heating system 80 may include one or more sensors configured to monitor the fluid flowing through it. For example, temperature sensors may be mounted in the fluid heating system 80 to detect the temperature of the fluid flowing through the fluid cartridge 110. In some embodiments, a first temperature sensor may be located at or near the fluid inlet leading to and / or the fluid outlet exiting the sensor, such that it detects the temperature of the fluid flowing through the fluid cartridge 110 before the fluid enters the sensor and after the fluid exits the sensor. In some embodiments, additional sensors may be located in the middle portion of the sensor to detect the process of temperature rise in the fluid within the fluid cartridge 110.

[0069] The console 20 may further include one or more additional sensors, such as pressure sensors and / or bubble sensors. For example, the console 20 may include pressure sensors 70 (shown as a pair of pressure sensors) configured to monitor the system pressure of fluid exiting the cartridge 110 and flowing through the outflow fitting 104 to the surgical site. The fluid cartridge 110 may include a corresponding pressure sensor interface 72, such as a flexible membrane (e.g., Figure 3 As shown, when the fluid cartridge 110 is installed in the receiver 52 of the control console 20, the pressure sensor interface allows the pressure sensor 70 to monitor the pressure of the fluid flowing through the fluid cartridge 110. The pressure sensor 70 can send information to the controller 30 and / or the display screen 44.

[0070] Figure 3Additional features of the housing 110 of the fluid fitting kit 100 are shown. The fluid housing 110 may include a housing 112 that defines a fluid passage through the interior of the housing 112. The fluid housing 110 may include a front face 116 and a rear face 118 opposite to the front face 116. The front face 116 is configured to face the door 50 of the console 20 when loaded in the receiving section 52, and the rear face 118 is configured to face the rear wall of the receiving section 52 of the console 20 when loaded in the receiving section 52. The fluid housing 110 may also include an upper edge 115 and a lower edge 114 opposite to the upper edge 115. The housing 112 of the fluid housing 110 may also include an opening 82, such as an elliptical opening, extending through the housing 112 from the front face 116 to the rear face 118. In some cases, the opening 82 may extend over a large portion of the length of the housing 112 (i.e., a large portion of the distance between the lateral edges of the housing 112) and / or a large portion of the height of the housing 112 (i.e., a large portion of the distance between the upper and lower edges of the housing 112). The opening 82 may be configured to receive a raised portion of the rear wall of the receiving portion 52, such as... Figure 1 The fluid heating system 80 is shown. When the fluid cartridge 110 is in its loaded position in the receiving section 52, the raised portion of the rear wall of the receiving section 52 may be elliptical, sized to fit through the elliptical opening 82 of the housing 112 of the fluid cartridge 110. In embodiments where the console 20 does not have a fluid heating system, the raised portion of the rear wall of the receiving section 52 may still be present. For example, inserting the raised portion of the rear wall of the receiving section 52 through the opening 82 of the fluid cartridge 110 may help to properly align the fluid cartridge 110 in the receiving section 52.

[0071] In some embodiments, the fluid cartridge 110 may include a fluid inlet port 103 and a fluid outlet port 105 located on a lateral side of the fluid cartridge 110. The fluid inlet port 103 may be coupled to an inflow fitting 102, and the fluid outlet port 105 may be coupled to an outflow fitting 104. The cartridge 110 may define an internal fluid passage through the interior of the cartridge housing 112 between the fluid inlet port 103 and the fluid outlet port 105. In embodiments of the fluid management system 10 including fluid heating capability, the internal fluid passage may include a sensor. A length of flexible pump fitting 106 of the cartridge 110 is configured to engage an inflow pump and be compressed by rollers of the inflow pump 60. This length of flexible pump fitting extends from the fluid inlet port 103 to a connection 107 of the cartridge 110, which leads to the fluid passage defined through the interior of the cartridge 110. The flexible pump fitting 106 may be a separate length of fitting from the inflow fitting 102 and the outflow fitting 104. In some cases, the flexible pump fitting 106 may extend through an arcuate passage between the fluid inlet port 103 and the connection portion 107, such that the flexible pump fitting 106 follows the rotational path of the rollers flowing into the pump 60. The inlet port 103, the outlet port 105, and / or the connection portion 107 may be formed as part of the housing 112, or may be formed separately and attached thereto.

[0072] The fluid cartridge 110 may also include an exhaust valve 90 configured to release air from the interior of the fluid cartridge 110 to the atmosphere. For example, the fluid cartridge 110 may include a vent hole comprising a hydrophobic membrane, thereby allowing air (including air bubbles entrained in the fluid) to pass through the hydrophobic membrane while preventing fluid from passing through it. The air can then be discharged to the atmosphere through the exhaust valve 90.

[0073] The fluid cartridge 110 may also include one or more retaining features configured to interact with the console 20 to retain the fluid cartridge 110 in the receiving portion 52 of the console 20. For example, the fluid cartridge 110 may include a retaining tab 120 extending from the lower edge of the housing 112 of the fluid cartridge 110 and / or a retaining tab 124 extending from the upper edge 115 of the housing 112 of the fluid cartridge 110, the retaining tabs being configured to engage a cooperating retaining feature of the console 20, as will be described in more detail below.

[0074] When door 50 is opened, retaining tab 120 can engage with retaining tab 122 of control panel 20 (see...). Figure 2 The fluid cartridge 110 interacts with each other to hold it in the pop-up position without causing it to fall out of the receiving section 52 of the console 20. For example, as Figure 4As shown, when the door 50 is opened, the box 110 can tilt outward from the receiving portion 52 at an acute angle to the vertical direction without falling completely out of the receiving portion 52. In other words, when the door 50 is opened, the box 110 can tilt outward from the fully loaded position to the pop-out position. In the fully loaded position, the box 110 is vertically loaded into the receiving portion 52 of the console 20. In the pop-out position, the upper edge of the box 110 has moved laterally out of the receiving portion 52, while the lower edge of the box 110 remains in the receiving portion 52. When the door 50 is opened, the interaction between the retaining tab 120 of the fluid box 110 and the retaining tab 122 of the console 20 can hold the box 110 in the pop-out position at an acute angle to the vertical direction. In some cases, for example, the acute angle can be in the range of about 20° to about 50°, about 20° to about 40°, about 25° to about 35°, or about 30°. Therefore, when the door 50 is opened, the interaction between the retaining tabs 120 and 122 prevents the box 110 from falling completely out of the receiving section 52 due to gravity. In other words, the interaction between the retaining tabs 120 and 122 supports the box 110 in the pop-out position at an acute angle to the vertical direction, preventing the box 110 from falling completely out of the receiving section 52 due to gravity. Furthermore, before the door 50 is closed, the interaction between the retaining tabs 120 and 122 allows the box 110 to be installed in the receiving section 52 in the pop-out position and to be in a ready-to-use state.

[0075] Figure 5 and Figure 5A More details of the retaining tab 120 of the fluid cartridge 110 are shown. As shown, the retaining tab 120 can extend from the lower edge 114 of the housing 112 of the fluid cartridge 110. In some cases, the retaining tab 120 can extend along a large portion of the length of the lower edge 114 of the housing 112 of the fluid cartridge 110 (e.g., see...). Figure 3 The retaining tab 120 may include a base attached to the lower edge 114, and the retaining tab 120 may extend to a free end. The retaining tab 120 may include an engagement surface 126 extending at an acute angle to the front face 116 and / or the rear face 118 of the housing 112 of the fluid cartridge 110. The free end of the retaining tab 120 may include a lip 130 projecting at an angle from the free end.

[0076] Go to Figure 6 and Figure 6AFurther details of the retaining tab 122 of the console 20 are shown. The retaining tab 122 may be a protrusion that projects upward from the lower surface 21 of the housing 22 of the console 20 into the interior of the receiving portion 52. The retaining tab 122 may include an engagement surface 128 that extends at an acute angle to the lower surface 21 of the housing 22 of the console 20, thereby providing a wedge shape for the retaining tab 122. The console 20 may also include a recess 132 in the inner wall of the receiving portion 52. The recess 132 may be configured to receive the lip 130 of the retaining tab 120 of the fluid cartridge 110.

[0077] Figure 7 The interaction between the retaining tab 120 of the fluid cartridge 110 and the retaining tab 122 and recess 132 of the console 20 is illustrated. When the fluid cartridge 110 is inserted into the receiving portion 52, the retaining tab 120 of the fluid cartridge 110 can be positioned between the retaining tab 122 and the recess 132, with a lip 130 extending into the recess 132. When the cartridge 110 is tilted outward from the receiving portion 52, the engagement surface 126 of the retaining tab 120 of the fluid cartridge 110 can abut, contact, rest against, or otherwise juxtapose with the engagement surface 128 of the retaining tab 122 of the console 20, while the lip 130 of the retaining tab 120 extends into the recess 132. The interaction between the retaining tab 120 of the fluid cartridge 110 and the retaining tab 122 and recess 132 of the console 20 supports the fluid cartridge 110 in its pop-out position, wherein the housing 112 of the fluid cartridge 110 lies in a plane at an acute angle θ to the vertical direction. In this position, before closing the door 50, the fluid cartridge 110 can be considered to be in a ready-to-use state. When the door 50 is closed, or before closing the door 50, the housing 112 of the fluid cartridge 110 will tilt to a vertical position (loading position) in the receiving section 52, where the housing 112 of the fluid cartridge 110 is located in a vertical plane. Furthermore, when the door 50 is opened after using the fluid cartridge 110, the fluid cartridge 110 may tilt out of the receiving section 52 without falling completely out of the receiving section 52 due to gravity. Therefore, when the engagement surface 126 of the retaining tab 120 abuts against the engagement surface 128 of the retaining tab 122 of the control panel 20, the interaction between the lip 130 of the retaining tab 120 and the recess 132 helps to support the cartridge 110 in the pop-out position at an acute angle to the vertical direction, preventing the cartridge 110 from falling completely out of the receiving section 52 due to gravity.

[0078] The console 20 may also include a retaining mechanism configured to releasably engage the fluid cartridge 110 to hold the fluid cartridge 110 in a loaded vertical position within the receiving section 52, where the fluid cartridge 110 is ready for use. For example, the retaining mechanism may be configured to releasably engage the upper portion of the housing 112 of the fluid cartridge 110. In the locked position, the retaining mechanism prevents the fluid cartridge 110 from tilting outwards, thus holding the fluid cartridge 110 in the loaded vertical position within the receiving section 52. Figure 8 and Figure 8A An exemplary retaining mechanism is shown. The retaining mechanism may include a latch 142 configured to engage a retaining tab 124 on the upper edge 115 of the housing 112 of the fluid cartridge 110 when in the vertical position of loading in the receiving section 52 (see [link to relevant documentation]). Figure 9 The retaining mechanism may also include an actuator (such as button 140) that can be actuated to release latch 142 from retaining tab 124. Pressing button 140 causes latch 142 to pivot about pivot axis 148, thereby disengaging latch 142 from retaining tab 124. The retaining mechanism may include a spring, such as torsion spring 146, that biases latch 142 to a locked position where latch 142 engages retaining tab 124. Pressing button 140 overcomes the biasing force of torsion spring 146 to move latch 142 from the locked position to an unlocked position where latch 142 disengages from retaining tab 124. The retaining mechanism may also include pusher 144. Pusher 144 may be actuated by latch 142, and in some cases, pusher 144 and latch 142 may be an integral component. Thus, pressing button 140 can simultaneously actuate (e.g., pivot) latch 142 and pusher 144. When button 140 is pressed, pusher 144 can apply an outward force to the rear surface 118 of housing 112 of fluid cartridge 110, causing the upper part of fluid cartridge 110 to tilt outward from receiving part 52 to pop-out position or towards pop-out position.

[0079] The retaining tab 124 on the upper edge 115 of the housing 112 of the fluid box 110 is engaged. Figure 9 This can be described more easily. The retaining tab 124 may include a shoulder 125 configured to face the latch 142 when engaged with the latch. Figure 10 As shown in the cross-sectional view, latch 142, in the loaded position, can retain the tab 124 extending above it, with the lip of latch 142 engaging the shoulder 125 of the tab 124. Pivoting latch 142 about pivot pin 148 disengages latch 142 from engagement with the tab 124 (i.e., disengages latch 142 from the tab 124), while moving pusher 144 engages with the rear face 1189 of the housing 112 of fluid cartridge 110.

[0080] Figure 11 This is a schematic cross-sectional view showing the fluid cartridge 110 housed in the receiving section 52 of the housing 22 of the control console 20 of the fluid management system 10. (As shown) Figure 11 As shown, in the fully loaded position ready for use, the fluid cartridge 110 can be vertically arranged in the receiving section 52, with the housing 112 of the fluid cartridge 110 located in the vertical plane V. The door 50 can be closed, facing the front surface 116 of the fluid cartridge 110, and the rear surface 118 of the fluid cartridge 110 can face the rear wall of the receiving section 52. The latch 142 is also shown engaging with the retaining tab 124 of the fluid cartridge 110 to hold the fluid cartridge 110 in the vertical starting position.

[0081] The control console 20 may include one or more sensors configured to confirm whether the fluid cartridge 110 has been correctly positioned in the receiving section 52 and whether the door 50 has been closed before allowing the inflow pump 60 to operate. For example, the control console 20 may include one or more proximity sensors, contact sensors, magnetic sensors, etc., to determine whether the fluid cartridge 110 is correctly positioned in the receiving section 52 before allowing the controller 30 to activate the inflow pump 60. Once correctly positioned and the door 50 closed, the controller 30 may initiate operation of the inflow pump 60 to begin supplying fluid to the treatment site during a medical procedure.

[0082] It should be understood that this disclosure is illustrative in many respects. Changes may be made in details, particularly in the shape, size, and arrangement of steps, without departing from the scope of this disclosure. Where appropriate, this may include using any feature employed in one exemplary embodiment in other embodiments. Of course, the scope of this disclosure is defined by the language of the appended claims.
