[0022] The following description relates to a manifold-integrated anesthesia ventilator system. A manifold-integrated anesthesia ventilator system may include multiple subsystems and / or modules, such as an inlet module, a mixer module, a vaporizer module, and a breathing circuit. In this document, an anesthesia ventilator system refers to a system capable of delivering anesthesia and / or functioning as a ventilator. A manifold-integrated anesthesia ventilator system may include: a core component that includes subsystems and / or modules; an interface encapsulation component that encapsulates the core component and provides a user interface; and optionally, a housing that is further coupled to the interface encapsulation component and includes additional feature structures. Conventionally, such as Figure 1 As shown, the subsystems / modules are constructed in a distributed manner, with each subsystem / module fluidly connected in series via tubing. The flexibility of the tubing facilitates the positioning of module controls, allowing the operator to access these controls. The inventors have recognized the problems with distributed systems. Leaks are prone to occur at the connection points between the tubing and the modules. Additionally, the tubing can occupy a significant amount of space, requiring a larger housing for the anesthesia ventilator system. Furthermore, if any module is updated, removed, or added, the distributed layout requires substantial design and manufacturing work to update the entire anesthesia ventilator system, including each module and subsystem, as well as the housing.

[0023] The manifold integrated anesthesia ventilator system may include a core component located within an interface package assembly, which may be located within a housing. Figure 2 The block diagram illustrates an example of the core component. The core component may include a common gas manifold configured to receive and distribute multiple gases (air, O2, N2O, and / or mixtures thereof) between modules. Each module of the core component can be directly and permanently coupled to the common gas manifold, thereby eliminating the need for tubing to fluidly connect the modules. In this way, the system is in a modular construction and can simplify the updating, removal, and / or addition of modules. Additionally, modules can be directly coupled to the manifold or can be integrally formed with the manifold, thereby reducing or essentially eliminating the need for tubing. Furthermore, each module in the module can be manufactured and individually leak-tested before assembling the manifold-integrated anesthesia ventilator system. Once assembled, leaks between the modules and the common gas manifold can be tested. This process is similar to assembling and testing... Figure 1 Compared to the distributed anesthesia ventilator system with tubing shown, this process is simpler and easier to diagnose.

[0024] Figure 3 An example of a core component in a trunk configuration is shown. The common gas manifold can include multiple flow paths through which gas can be transferred between different modules. As described above, the core component of a manifold-integrated anesthesia ventilator system can be easily adapted to different configurations, such as... Figure 4An alternative example of a core component that does not have a vaporizer module. Alternatively, the core component of a manifold integrated anesthesia ventilator system may be located as follows: Figure 5 Cross-sectional view and Figure 6 The stacked configuration is shown in the perspective view. Figures 7 to 12 The image shows an example of the modules included in the core components. The core components of the manifold integrated anesthesia ventilator system can be combined with, for example... Figure 13 The interface encapsulation component is shown in the diagram. This component can then be assembled into several different housings. The housings can vary based on the specific functionality of the manifold-integrated anesthesia ventilator system or on user preferences. Figures 14 to 15 Examples of interface encapsulation components located within different housings are shown.

[0025] Now go to Figure 1 This illustration shows a simplified example of a prior art anesthesia ventilator system 100. The anesthesia ventilator system 100 may include an inlet subsystem 102 fluidly connected to a mixer subsystem 106 via a first conduit 104. As an example, the first conduit 104 may include three different tubes, each for N2O, O2, and air, respectively. The mixer subsystem 106 may then be fluidly connected to a vaporizer subsystem 110 via a second conduit 108. Additionally, the vaporizer subsystem 110 may be fluidly connected to a breathing circuit 114 via a third conduit 112.

[0026] Each tubing connection between subsystems (e.g., mixer subsystem 106, vaporizer subsystem 110, etc.) can be a potential leak point in the anesthesia ventilator system 100. Additionally, tubing can occupy significant space, requiring a large housing. Furthermore, the physical arrangement of the subsystems is constrained by the tubing connections. If a subsystem is removed, the anesthesia ventilator system 100 may require adjustments to the subsystems directly fluidly connected to it. For example, removing the vaporizer subsystem 110 may require adjustments to both the mixer subsystem 106 and the breathing circuit 114. Removing the vaporizer subsystem 110 may also require further rearrangement of the physical controls of the anesthesia ventilator system 100's housing.

[0027] Alternatively, a manifold integrated anesthesia ventilator system, including its core components, can at least partially overcome [the challenges]. Figure 1The conventional design shown presents challenges, with the core component comprising modules constructed to be interchangeable and removable. In one example, a common gas manifold can provide the gas for the anesthesia ventilator system. The core component of a manifold-integrated anesthesia ventilator system can be modular, allowing modules to be added, removed, and / or updated without refactoring the entire system. Furthermore, a physical, direct connection between the module and the common gas manifold is less prone to leakage than a tubing connection. Even when the core component is modularly updated, the interface encapsulation component encapsulating the core component can remain unchanged when the core component is modified, simplifying and streamlining the manufacturing of different product lines using the core component.

[0028] Now go to Figure 2 This diagram illustrates a block diagram of a manifold-integrated anesthesia ventilator system 200, including a core component 201. The core component may include a common gas manifold 204 and one or more modules 203. As an example, the one or more modules may each be configured as a manifold to be connected to the common gas manifold 204. The one or more modules 203 may not include tubing. The one or more modules 203 may include an inlet module 202 fluidly connected to a gas source, and the inlet module 202 may be configured to allow gas to flow into the common gas manifold 204. The common gas manifold 204 may distribute gas to a mixer module 206 and a breathing circuit 212. The core component 201 of the manifold-integrated anesthesia ventilator system may optionally include additional modules, such as, but not limited to, a vaporizer module 208 and a gas monitoring module 210. Each of the mixer module 206, the breathing circuit 212, and the optional vaporizer module 208 and gas monitoring module 210 may be fluidly connected to each other via the common gas manifold 204 and fluidly connected to the inlet module 202. One or more modules 203 can each be directly fluidly connected to the common gas manifold 204. Additionally, accessory outputs / inputs 218 for the anesthesia ventilator system (such as, but not limited to, suction, purging, supplemental O2, high-flow nasal cannula (HFNC), supplemental common gas outlet (ACGO), intravenous administration pumps / controls, etc.) can be fluidly connected to the common gas manifold 204. In this way, removing, adding, or updating modules of the core components of the manifold-integrated anesthesia ventilator system may require minor modifications to individual modules without needing to update other components of the manifold-integrated anesthesia ventilator.

[0029] The manifold-integrated anesthesia ventilator system 200 may further include a controller 214. The controller 214 may be communicatively coupled to pneumatic actuators, valves, sensors, etc., of the core component 201 of the manifold-integrated anesthesia ventilator system, either wired or wirelessly. The controller 214 may include a central processing unit (CPU) or other electronic components capable of performing processor functions to operate one or more modules of the core component and the common gas manifold. The controller 214 may be communicatively coupled to a user interface 216, either wired or wirelessly. In this way, a user can control the actuators and valves of the core component 201 of the manifold-integrated anesthesia ventilator system from anywhere the user interface 216 is located. For example, the user interface 216 may include a keyboard and a mouse. Additionally or alternatively, the user interface 216 may include a touchscreen or physical buttons positioned on the housing, or graphical controls for an application running on a physically separate smartphone or tablet. In this way, the physical location of the actuators of one or more modules of the core component 201 of the manifold integrated anesthesia ventilator system can be accessed by the user from any location, and the location of the modules within the manifold integrated anesthesia vaporizer system can be independent of the clinician's need to physically access the pneumatic controls.

[0030] Simple reference Figures 7 to 12 The diagram shows a non-limiting example of a common gas manifold 204 and one or more modules 203. Figures 7 to 12 The diagram includes multiple valves and other actuators that can be communicatively coupled to controllers such as controller 214 of a manifold integrated anesthesia ventilator system. Figure 7 A non-limiting example of a common gas manifold 204 is shown. The common gas manifold 204 may include multiple flow paths 702. Each of the multiple flow paths may be an independent flow path. In some examples, each of the multiple flow paths may be a parallel flow path. Hereinafter, a flow path refers to the manner of gas flow rather than the physical location of the manifold. Hereinafter, a parallel flow path is a flow path in which each flow path is an independent flow path and the gas flowing through each flow path does not mix with other gases within the parallel flow path. The physical manifold through which the gas flows may be parallel or may not be parallel. Each flow path may be dedicated to one type of gas used in a manifold-integrated anesthesia ventilator system. For example, the common gas manifold 204 may include six flow paths. The six flow paths may be individually configured to allow the flow of O2, N2O, air, drive gas, purge gas, and pressure-regulated O2. Other numbers of flow paths included in the common gas manifold are also considered to be within the scope of this disclosure. Each flow path may be parallel to other flow paths and may not be directly fluidly connected to each other. In some examples, the physical length of each flow path may be equal.

[0031] The common gas manifold 204 may include a connector port 704. Connector port 704 may be a single port containing multiple pneumatic and electrical connections. Connector port 704 can provide fluid connections to each flow path in the flow path of the common gas manifold 204. As an example, connector port 704 may be used if any gas from the manifold-integrated anesthesia ventilator system will be connected to additional accessory components. Alternatively, connector port 704 can be used for direct connection to the common gas manifold 204 of the manifold-integrated anesthesia ventilator system, interface enclosure components, and optional housings.

[0032] Module 203 may be fluidly connected to a common gas manifold 204. In some examples, the common gas manifold may include a connection path 706 connecting the output of one module to the input of another module. In other examples, such as inlet module 202, the module may be directly connected to flow path 702. In some examples, common gas manifold 204 may include a valve 708 positioned in the flow path between the module and the flow path in flow path 702.

[0033] Now go to Figure 8 A non-limiting example of inlet module 202 is shown. Inlet module 202 can be physically coupled to the upstream end of a common gas manifold, such as... Figure 7 As shown. In an alternative example, inlet module 202 may be integrally formed as part of common gas manifold 204. In such examples, inlet module 202 may not be easily detached from common gas manifold 204. The inlet module may include inlet 802 to introduce O2, air, and N2O into a designated flow path of common gas manifold 204. In some examples, the inlet module may not include an N2O inlet. In some examples, gases other than N2O or alternatives to N2O may be introduced into common gas manifold 204 through inlet module 202. In some examples, inlet module 202 may be coupled to a corresponding gas cylinder and / or coupled to an internal supply of O2, air, and N2O. In some examples, inlet module 202 may be configured to combine O2 and air to coupled to a drive gas flow path of common gas manifold 204.

[0034] Inlet module 202 may include a pressure reducing valve 804 positioned in the fluid path between the inlet 802 and the output of common gas manifold 204. Inlet module 202 may further include a pressure regulator 806 positioned between the pressure reducing valve 804 and the output of common gas manifold 204. Pressure regulator 806 can reduce the pressure received from inlet 802 to a usable pressure. In some examples, the O2 fluid path may be branched into an O2 outlet and a regulated O2 output. A second pressure regulator 808 may be positioned between the main O2 fluid path and the regulator O2 output.

[0035] In some examples, the inlet module may include different types or quantities of gas. In some examples, inlet module 202 may be replaced by different inlet modules with different quantities or types of gas. Replacing inlet module 202 with a different inlet module does not require modification of the common gas manifold 204 or other modules of the core component 201 of the manifold integrated anesthesia ventilator system.

[0036] Now go to Figure 9 A non-limiting example of a mixer module 206 is shown. The mixer module 206 can be directly coupled to the N2O, air, and O2 flow paths of a common gas manifold 204. In this way, the mixer module 206 can receive the gases to be mixed via the common gas manifold 204 instead of by direct coupling to the inlet module 202. The mixer module 206 can output the mixed gas in a single output back to the common gas manifold 204 via an additional flow path or connection path (such as connection path 706). In some examples, a flow path for N2O may not be included, and O2 can be combined with air without N2O. In alternative examples, N2O can be replaced with a different gas. The mixer module 206 may include a flow regulator 902. Each gas inlet in the received gas inlets can be directed to a flow regulator in the flow regulator 902, and the outputs from the flow regulator 902 can then be combined to output a single mixed gas output. The flow regulators can be used to control the flow rate of each gas to the common mixed gas output, thereby controlling the composition of the mixed gas.

[0037] In one example, mixer module 206 can be configured as either a first mixer module or a second mixer module. For example, the first mixer module can be a high-flow mixer module, and the second mixer module can be a low-flow mixer module. The first and second mixer modules may be interchangeable with respect to the core component 201 of the manifold-integrated anesthesia ventilator system 200. In one example, the portions of the first and second mixer modules that connect to the common gas manifold 204 can be formed in the same manner, while the mixing components can be replaced according to the required flow rate. In this way, without updating the common gas manifold 204 or other modules of the core component of the manifold-integrated anesthesia ventilator system, the mixer module can be replaced or updated with mixer manifolds of different configurations to produce different manifold-integrated anesthesia ventilator system products.

[0038] Now go to Figure 10A non-limiting example of an optional evaporator module 208 is shown. Evaporator module 208 may be located downstream of mixer module 206. Evaporator module 208 may include an input 1002 for a liquid anesthetic. The liquid anesthetic may flow to storage tank 1004. Valve 1006 may be located in the flow path between input 1002 and storage tank 1004. Storage tank 1004 may be fluidly coupled to liquefied gas converter 1008. Liquefied gas converter 1008 may convert the liquid anesthetic into a gaseous anesthetic. For example, liquefied gas converter 1008 may include a heater to evaporate the liquid anesthetic into a gaseous phase. As another example, liquefied gas converter may include a pressurized injector to convert the liquid anesthetic into a gaseous phase. The gaseous anesthetic may flow from liquefied gas converter 1008 to a flow path downstream of the mixed gas (e.g., output by mixer module 206). Flow controller 1010 may be located between the output of liquefied gas converter 1008 and the mixed gas flow. The flow controller can control the amount of gaseous anesthetic mixed into the gas mixture. The gas mixture with the gaseous anesthetic can be referred to as fresh gas. The evaporator module 208 can receive the gas mixture input and output fresh gas.

[0039] In some examples, such as when anesthetic drugs are delivered intravenously, the vaporizer module 208 may not be used, and the core components of the manifold-integrated anesthesia ventilator system may be adjusted accordingly without modifying the common gas manifold or other modules, as described below relative to... Figure 4 Further details are provided.

[0040] Now go to Figure 11 A non-limiting example of a gas monitoring module 210 is shown. The gas monitoring module 210 can receive a sample gas inlet 1102 from a patient line. The patient line may be the output of a breathing circuit (such as breathing circuit 212). The sample gas can flow to a water separator 1104. The water separator 1104 can condense and capture any water vapor in the sample gas. The sample gas can then flow to a gas analyzer 1106. The gas analyzer 1106 can determine the concentrations of O2, CO2, and anesthetic in the sample gas. An inlet flow controller 1108 may be located between the water separator 1104 and the gas analyzer 1106. The inlet flow controller can control the flow rate of the sample gas introduced into the gas analyzer 1106. An outlet flow controller 1110 may be located downstream of the gas analyzer 1106 and can control the flow rate of the analyzed sample gas output by the gas analyzer 1106 after analysis. The gas monitoring module 210 can output exhaust gas. In some examples, the exhaust gas can be recirculated back into the breathing circuit. In an alternative example, exhaust gases can be output to a purging system.

[0041] Now go to Figure 12A non-limiting example of a breathing circuit 212 is shown. The breathing circuit may include a fresh gas input 1202. As discussed above, the fresh gas input may be output from an evaporator module (such as evaporator module 208). Fresh gas may be directed to an input flow path 1204 and flow to the inspiratory branch of the patient connector 1208. A valve 1206 may be positioned in the input flow path 1204 to control the flow direction entering the inspiratory branch. Gas exhaled by the patient may enter the expiratory branch of the patient connector 1208 and flow into an output flow path 1212. A valve 1210 may be positioned in the output flow path 1212 to control the flow direction leaving the expiratory branch. In some examples, gas exhaled by the patient may be directed to an absorber 1214 to absorb exhaled CO2 and then return to the input flow path 1204. Excess gas that is not directed back to the input flow path 1204 may be directed to a waste flow path 1216 and a scavenging system. In some examples, the gas exhaled by the patient may not be recirculated, and the expiratory branch may be directly coupled to the waste flow path 1216. The waste flow path 1216 may include a pressure regulator 1218 positioned upstream of the purging system outlet to control the pressure of the gas introduced into the purging system. A driver flow path 1220 may fluidly connect to each of the input flow path 1204, the output flow path 1212, and the waste flow path 1216, and may be coupled to a gas driver to propel gas in and out of the patient. In one example, the driver flow path 1220 may be coupled to a bag 1222. In another example, the driver flow path 1220 may be coupled to a bellows and may include a valve to control the airflow direction.

[0042] Figure 3 An example of a core component 300 of a manifold integrated anesthesia ventilator system 200 is shown. The core component 300 may be... Figure 2 The example shown is a core component 201 of a manifold integrated anesthesia ventilator system. Core component 300 may be an example of a core component in a trunk configuration (e.g., trunk core component 300).

[0043] In the trunk configuration, the common gas manifold can serve as the trunk, and one or more modules of the core components of the manifold-integrated anesthesia ventilator system can be directly and fixedly connected to the side of the common gas manifold. The common gas manifold can be a continuous manifold that is separable from and spaced apart from one or more modules. Direct fixed connection can include, but is not limited to, bolted connections, clamping, magnetic fixation, other mechanical fasteners capable of maintaining a fluid-tight connection, and adhesive bonding. The common gas manifold 302 can be... Figure 2An example of a common gas manifold 204 is shown. Gas can flow from upstream end 322 through common gas manifold 302 to downstream end 304. Common gas manifold 302 may include connector port 305. Connector port 305 may be... Figure 7 An example of the connector port of the common gas manifold 204 shown.

[0044] The inlet module 320 can be connected to the upstream end 322 of the common gas manifold 302. The inlet module 320 can be... Figure 2 and Figure 8 An example of inlet module 202. Mixer module 306 can be coupled downstream of inlet module 320 to common gas manifold 302. Mixer module 306 can be Figure 2 and Figure 9 An example of a mixer module 306 is provided, which can receive gas from inlet module 320 via common gas manifold 302 and output the mixed gas to evaporator module 308 via first connection path 307. Evaporator module 308 may be... Figure 2 and Figure 10 An example of an evaporator module 208. Evaporator module 308 can be directly connected downstream of mixer module 306 to the flow path of common gas manifold 302. Fresh gas output from evaporator module 308 can be output via second connection path 309 to gas monitoring module 316 and breathing circuit 318. Gas monitoring module 316 can be... Figure 2 and Figure 11 An example of a gas monitoring module 210. Gas monitoring module 316 can receive sample gas from breathing circuit 318 via a third connection path 311. Gas monitoring module 316 can also be directly connected to the flow path of common gas manifold 302. Breathing circuit 318 can be... Figure 2 and Figure 12 An example of the breathing circuit 212. In addition to being connected to the gas monitoring module 316 and the evaporator module 308 via the third connection path 311 and the second connection path 309 respectively, the breathing circuit 318 can also be directly connected to the downstream end 304 of the common gas manifold 302.

[0045] As described above, the core component 300 in a trunk configuration may include one or more modules (e.g., multiple modules) bolted to the common gas manifold 302. Each module performs a separate function of the manifold-integrated anesthesia ventilator system and can be interchanged or updated with different modules performing that function. Additionally, the need for pneumatic tubing to extend between multiple modules is avoided, thereby saving space and eliminating potential leakage points introduced by pneumatic tubing connections. Another advantage of core components of the manifold-integrated anesthesia ventilator system (such as core component 300) is that manufacturers can easily add and / or remove modules as needed to create one or more products in a product line, each including at least the same common gas manifold.

[0046] As an example, such as Figure 4 As shown, core component 300 can be easily converted into intravenous anesthesia core component 400. Intravenous anesthesia core component 400 may include some of the same components as core component 300; these components are numbered the same and will not be described again. Intravenous anesthesia can use intravenous drugs instead of vaporized gases to anesthetize the patient. Therefore, the manifold integrated intravenous anesthesia ventilator system may not include a vaporizer module, such as vaporizer module 308.

[0047] To convert core component 300 into an intravenous anesthesia core component, the vaporizer module can be removed without altering the common gas manifold and remaining modules. In one example, the vaporizer module can be replaced by a module connector 402. Module connector 402 can be a single flow path bolted at a first end to a first connection path 307 and at a second end to a second connection path 309 in the same physical location as vaporizer module 308. Module connector 402 may also include a cap terminating the flow path, which has already connected the vaporizer module to the common gas manifold 302. In this way, mixer module 306 can still be connected to breathing circuit 318 via module connector 402. Module connector can be a flow path between open flow paths when the module is removed. Module connector 402 can act as a passageway for gas flow and may not include pneumatic components or valves. Replacing the vaporizer module with module connector 402 can be an efficient way to adapt core component 300 into intravenous anesthesia core component 400. Figure 3 Core component 300 and Figure 4 The core components of the intravenous anesthesia system 400 are compared, and other modules and other parts of the common gas manifold can be substantially the same and unchanged.

[0048] In alternative examples, core component 300 can be modified by the manufacturer in different ways according to user needs. Modules can be removed and replaced with module connectors and / or end caps to always maintain the fluid connectivity of the remaining modules. Modules can also be easily replaced and / or updated to prevent deterioration of the manifold-integrated anesthesia ventilator system. In some examples, a second common gas manifold can be coupled to common gas manifold 302 to expand core component 300 and add other modules to the core component. In some examples, the second common gas manifold can be coupled to common gas manifold 302 via connector port 305.

[0049] Now go to Figure 5 and Figure 6 The illustration shows an alternative example of core component 500. Core component 500 can be an example of a stacked configuration core component. Reference axis 502 is included for comparison. Figure 5 and Figure 6 The view in the diagram includes a reference axis comprising an x-axis, a y-axis, and a z-axis. The y-axis may be parallel to the longitudinal axis of the core assembly 500 and parallel to the gas flow direction through the core assembly 500. The x-axis may be parallel to the lateral direction of the core assembly 500. Figure 5 and Figure 6 A simplified illustration of core component 500 is shown. Modules of core component 500 may include... Figures 7 to 12 The flow path shown is the same as the flow path and components of other parts. Core component 500 may also include connecting flow paths to connect components not otherwise specified. Figures 5 to 6 The module shown in the image.

[0050] Figure 5 This is a cross-sectional view of the core component 500, showing two flow paths of the common gas manifold 504. The common gas manifold 504 can be... Figure 2 An example of a common gas manifold 204. Common gas manifold 504 may include six flow paths, as described above with respect to common gas manifold 302. Therefore, Figure 5 The cross-sectional view shows two of the six flow paths. Other arrangements of the flow paths are also considered, and are discussed below. Figure 6Further description. The common gas manifold 504 can be divided into multiple distinct segments, which can be integrated into stacked modules. In one example, the common gas manifold can be divided into five distinct segments: a first segment 504a, a second segment 504b, a third segment 504c, a fourth segment 504d, and a fifth segment 504e. Each of the multiple segments can be integrally formed into a module of the core component 500. The faces of each module in the xz plane can be configured to be bolted to adjacent modules. When the modules are bolted together (e.g., attached in a coplanar contact manner), the corresponding segments of the common gas manifold align, thereby forming a flow path to carry gas between modules.

[0051] The first section 504a can be integrally formed into the inlet module 506 and includes the upstream end 514 of the core component 500. The mixer module 508 can be bolted to the downstream end of the inlet module 506. The second section 504b of the common gas manifold 504 can be integrally formed into the mixer module 508 and can be aligned with the first section 504a when the two are bolted together. The evaporator module 510 can be bolted to the downstream end of the mixer module 508. The third section 504c can be integrally formed into the evaporator module 510. The gas monitoring module 512 can be bolted to the downstream end of the evaporator module 510. The fourth section 504d of the common gas manifold 504 can be integrally formed into the gas monitoring module 512. The breathing circuit 513 can be bolted to the downstream end of the gas monitoring module 512. The fifth section 504e of the common gas manifold 504 can be integrally formed into the breathing circuit. When the modules of the core component 500 are connected together, the sections of the common gas manifold 504 integrally formed into the corresponding modules can form a continuous flow path for the gas.

[0052] Modules of the core component 500 can be added, removed, reconfigured, and / or replaced according to the required modules of the anesthesia ventilator system. For example, a manifold integrated anesthesia ventilator system can be modified to not have a vaporizer module or to have multiple breathing circuits.

[0053] Core component 500 may further include an upstream end cap 518 positioned at an upstream end 514 of the common gas manifold 504. The upstream end cap 518 may seal the upstream end of the common gas manifold 504 to prevent leakage. Core component 500 may further include a downstream end cap 520 positioned at a downstream end 516 of the common gas manifold 504. The downstream end cap 520 may seal the downstream end of the common gas manifold 504 to prevent leakage. In some examples, the downstream end cap 520 may include accessory outputs and inputs (e.g., accessory outputs and inputs 218) fluidly coupled to the common gas manifold 504, such as patient gas samples, high-flow nasal oxygen, or auxiliary common gas outlets.

[0054] Now go to Figure 6 This shows a view of the core component 500 as seen along the y-axis through the upstream or downstream end, through the upstream end cap 518 or the downstream end cap 520. Figure 6 The view illustrates six flow paths of the common gas manifold 504. The spatial arrangement of the flow paths of the common gas manifold 504 in the xz plane is not particularly limited. In one example, the spatial arrangement of the flow paths of the common gas manifold 504 can be the same in each module of the core component 500. In another example, the spatial arrangement of the flow channels can vary, and the connections between each module can be different. The spatial arrangement of the flow paths of the common gas manifold 504 can be a circular arrangement or a single row along the x-axis or z-axis. Additionally, as... Figure 6 As shown, the flow paths of the common gas manifold 504 can have equal diameters, or the flow paths can be formed with different diameters. Furthermore, although shown as circular in this document, other flow path shapes are also considered.

[0055] Core component 300 and intravenous anesthesia core component 400 may include a first product and a second product of a product line. The product line may include components with common or overlapping structural features as well as differences. For example, a common gas manifold including multiple flow paths may be a common structural feature of the product line, these multiple flow paths fluidly connecting modules of the core component of the manifold-integrated anesthesia ventilator system. Products in the product line may include different modules directly fluidly connected to the common gas manifold. For example, the first product (e.g., core component 300) may include an inlet module, a mixer module, a vaporizer module, a gas monitoring module, and a breathing circuit. The second product (e.g., intravenous anesthesia core component 400) may include the same inlet module, mixer module, gas monitoring module, and breathing circuit as the first product, and may also include a module connector replacing the vaporizer module.

[0056] In the main configuration, the common gas manifold can be formed as a continuous component, with modules bolted to this continuous component, such as... Figure 3 and Figure 4 As shown. In a stacked configuration, the common gas manifold can be manufactured as individual segments, which form a continuous flow path by bolting the modules together, wherein each module, including the common gas manifold, is arranged to align to form a flow path as shown. Figure 5 and Figure 6 The section of the common gas manifold shown. As described above, the first and second products can both be in a trunk configuration or both in a stacked configuration.

[0057] Manifold integrated anesthesia ventilator systems may include core components, such as Figures 2 to 6The core components are shown. A manifold-integrated anesthesia ventilator system can further include additional components such as housings, accessory components, and user interfaces. The core components of the manifold-integrated anesthesia ventilator system can be integrated into an interface encapsulation assembly. The interface encapsulation assembly can be configured to integrate with any core component protecting the tubing. For example, modules of the core components can be added, removed, and / or interchanged without changing the interface encapsulation assembly. The interface encapsulation assembly can be fitted into the housing of the manifold-integrated anesthesia ventilator system. The housing may include accessories that can be selected based on the usage of the manifold-integrated anesthesia ventilator system. As mentioned above, modules of the manifold-integrated anesthesia ventilator system can be added and removed based on the needs of the device without changing the interface encapsulation assembly. Such adjustments may be impossible if the modules are connected via tubing, where adding / removing modules may require significant repositioning of each component. In this way, multiple different anesthesia ventilator devices can be constructed as needed based on user requirements without significantly altering the core components or the interface encapsulation assembly. Manufacturing can benefit from economies of scale by manufacturing a large number of core component housings configured to add customizable components according to user needs. The following is relative to... Figures 13 to 15 Examples of manifold-integrated anesthesia ventilator systems are further shown and discussed, each of which may be a core component. Reference axes 1301, including x, y, and z axes, are provided for use... Figures 13 to 15 The x-axis can be parallel to the horizontal axis, and the y-axis can be parallel to the vertical axis. The z-axis can be parallel to the vertical axis.

[0058] Now go to Figure 13 The diagram shows the interface encapsulation component 1300. Figure 13 The view of the interface encapsulation component 1300 shown is partially transparent to show the outline of the core component 1302 located within and encapsulated by the interface encapsulation component 1300. The core component 1302 may be as described above regarding... Figures 2 to 6 Examples of core components discussed. Interface encapsulation component 1300 can be configured to connect to any core component of the product. In this way, the modules of core component 1302 can be changed while interface encapsulation component 1300 remains unchanged.

[0059] The interface encapsulation assembly 1300 may be generally shaped as a rectangular prism, including a front face 1304 and a back face positioned opposite the front face 1304 across the y-axis. The interface encapsulation assembly 1300 may further include a first side face 1306 and a second side face positioned opposite the first side face 1306 across the x-axis. The first side face 1306 and the second side face may extend from the front face 1304 to the back face. The front face 1304 may include an input 1308 and an output 1309. The input 1308 and the output 1309 may be coupled to a patient connector (such as...) for a breathing circuit. Figure 12 The patient connector 1208 of the breathing circuit 212 shown represents the inspiratory and expiratory portions. The front panel 1304 may further include a user interface 1313. The user interface 1313 may be... Figure 2 An example of user interface 216 is shown. In some examples, user interface 1313 may be a touchscreen and may also be used as a display. The back panel may include system connections for the manifold-integrated anesthesia ventilator system. System connections may include one or more gas connections, power connections, and communication connections. In one example, connections may be made via connector ports of a common gas manifold (such as connector port 704). The first side 1306 and the second side may be configured to attach to desired accessories or housing components of the manifold-integrated anesthesia ventilator system.

[0060] The interface encapsulation component 1300 may further include a top surface 1310 and a bottom surface 1312. The top surface 1310 and the bottom surface 1312 may be opposite each other across the z-axis. "Top" and "bottom" herein may refer to their relative positions with respect to the direction of gravity, as indicated by arrow 1303. The bottom surface 1312 may be generally rectangular. The top surface 1310 may be divided into a first segment 1310a and a segment 1310b, defined by the user interface 1313. Both the top surface 1310 and the bottom surface 1312 may be configured as accessories for connection to a manifold integrated anesthesia ventilator system.

[0061] The interface package assembly 1300 may have a width of 1314. The width 1314 may be slightly wider than the maximum width of the core assembly 1302 (e.g., 5%). The width 1314 may be slightly wider than the width of two gas cylinders of size E. The interface package assembly 1300 may have a first height 1316 at the front 1304 and may be tilted upwards to reach a second height 1318 at the rear. The first height 1316 may be smaller than the second height 1318. The second height 1318 may be slightly higher than the height of the gas cylinders of size E. The vertical positioning of the input 1308, output 1309, and display 1312 may be at proven heights for anesthesia ventilator systems.

[0062] The interface enclosure assembly 1300 may be laterally symmetrical (e.g., symmetrical across the zy plane). In this way, accessories can be easily attached to the interface enclosure assembly 1300 for left- or right-handed placement and / or use. For example, if a user interface is further attached to the interface enclosure assembly 1300, the user interface may be attached to a first side 1306 or a second side on the same interface enclosure assembly 1300. In some examples, an anesthesia manifold system may include the interface enclosure assembly 1300 without any other housing. Such examples can be used in space-constrained situations, such as in an operating room. Accessory inlets / outlets attached to the core assembly may include a patient interface positioned on the interface enclosure assembly 1300. For example, the interface enclosure assembly 1300 may include additional patient connections, ACGO, clearance, aspiration, auxiliary O2, and HFNC. Other accessories may also be directly attached to the interface enclosure assembly 1300. Accessories may include, but are not limited to, supplemental vaporizers, patient connections, CO2 canisters, clinical controls, displays, structural connections, working surfaces, and cuff arms.

[0063] In some examples, interface encapsulation components (such as...) Figure 13 The interface encapsulation component 1300 can be integrated into the housing. Figure 14 An example of an interface packaging assembly 1300 incorporated into a first housing 1400 is shown. The first housing 1400 may include casters 1402 coupled to the bottom surface of the interface packaging assembly 1300. The first housing 1400 may further include a drawer 1404 coupled to a first side of the interface packaging assembly 1300. In an alternative example, the drawer may be coupled to a second side of the interface packaging assembly 1300. The first housing 1400 may further include a shelf unit 1408 coupled to the top portions of the first and second sides of the interface packaging assembly 1300 and extending over the top surface of the interface packaging assembly 1300. The shelf unit 1408 may include one or more shelves. The sides of the shelf unit 1408 may be parallel to the first and second sides of the interface packaging assembly 1300 and may be coupled to an arm configured to hold a display. A first arm 1410 may be coupled to the first side of the shelf unit 1408 and may support a first display 1412 and a second display 1414. The second arm can extend from the second side of the shelf unit 1408 and can support the third display 1416 and the user interface 1418. The positions of the first arm 1410 and the second arm can be interchanged to provide an example of a housing in which the lateral positions (e.g., along the x-axis) of the first display 1412, the second display 1414, the third display 1416, and the user interface 1418 can be interchanged. In this way, components of a housing (such as the first housing 1400) can be laterally interchanged relative to the first and second sides of the interface encapsulation assembly 1300.

[0064] Now go to Figure 15 An example of an interface encapsulation assembly 1300 incorporated into a second housing 1500 is shown. The second housing 1500 can be included in a manifold integrated anesthesia ventilator system configured for intravenous anesthesia. For example, the core components included in the interface encapsulation assembly 1300 may not include a vaporizer module. The second housing 1500 may include casters 1502 coupled to the bottom surface of the interface encapsulation assembly 1300. The second housing 1500 may conform to the width, height, and depth of the interface encapsulation assembly 1300. The housing 1500 may include a rod 1504 extending vertically above the top surface of the interface encapsulation assembly 1300. A pump 1506 may be coupled to the rod 1504. The rod 1504 may also support an IV bag 1508. The pump 1506 may deliver intravenous anesthetic to the IV bag 1508 and then introduce it into the patient. The second housing 1500 may further include a first display 1510 coupled to a second side of the second housing 1500. A cuff arm 1516 may also be coupled to a second side of the second housing 1500. The cuff arm 1516 may be fluidly coupled to a breathing circuit included in the core assembly. The second display 1512 and user interface 1514 may be further coupled to a first side of the second housing 1500. The first side of the second housing 1500 may further include a retainer 1518 configured to hold a medical device to be used by a clinician. For example, the retainer 1518 may be configured to hold a laryngoscope.

[0065] The technical advantage of the manifold-integrated anesthesia ventilator system described herein is that it helps reduce fluid leakage by replacing tubing with a common gas manifold that connects to one or more modules. Modules can be bolted together and / or bolted to the common gas manifold in a physically safer and space-saving manner compared to using tubing. Furthermore, modules of the manifold-integrated anesthesia ventilator system using the common manifold can be easily removed, added, and updated to form different products in a product line, while still reusing many components between different products. In this way, the manufacturing advantage of increasing product quantity can be maintained, while still providing a range of products based on user needs. In addition, the manifold-integrated anesthesia ventilator system can include a core component, and additional feature structures and / or modifications can be positioned around the core component in an interface package assembly, wherein the interface package assembly can be adjusted without adjusting the core component, and other additional feature structures can be added to the housing attached to the interface package assembly, thereby providing further product scale advantages in manufacturing the core component and the interface package assembly.
