Description

Technical Field

[0001] Cross - reference to Related Applications This application claims the benefit of U.S. Provisional Patent Application No. 63 / 497,249, filed on April 20, 2023, the disclosure of which is incorporated herein by reference in its entirety.

[0002] This disclosure relates to a fluid injector system having a dual - display configuration for managing fluid injection procedures. In particular, this disclosure relates to a dual - display fluid injector system in which a main display is located within a sterile area and an overlay display is located outside the sterile area, thereby enabling easier, safer, and more accurate management of fluid injection procedures.

Background Art

[0003] Infusion systems, such as fluid injector systems (e.g., medical fluid delivery systems), can be used by medical personnel in medical diagnostic procedures and / or medical treatment procedures. For example, a medical professional can use a fluid injector system to inject one or more medical fluids into a patient. Fluid injector systems can be used for the pressurized infusion of medical fluids, such as radiographic contrast materials (e.g., contrast agents, contrast media) and / or cleaning agents such as saline, in medical imaging procedures such as angiography, computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), and positron emission tomography (PET). Fluid injector systems can also be used to deliver medical fluids or liquid pharmaceuticals to a patient during other procedures and / or treatments, including nuclear medicine imaging, molecular imaging, radiopharmaceutical injection, and cardiovascular local treatment. In some cases, fluid injector systems are designed to deliver a preset amount of one or more medical fluids at a preset pressure and / or flow rate.

[0004] In some cases, the fluid injector has at least one drive member, such as a piston connected to the syringe of the fluid injector via a connection to a plunger. The syringe may include a rigid barrel in which a syringe plunger is slidably disposed within the barrel. The drive member drives the plunger proximal and / or distal with respect to the longitudinal axis of the barrel to draw fluid into or deliver fluid from the syringe barrel.

[0005] In some cases, a fluid injector system may include a single screen and / or user interface associated with the fluid injector to manage the fluid injector procedure or to control the function of the fluid injector system. The screen / user interface is typically located in the injection chamber adjacent to the patient. However, such a configuration may limit the physician's ability to easily and accurately manage the fluid injector procedure in response to real-time events during angiography. In particular, the physician may be in a sterile area, and the screen / user interface may be outside the sterile fluid, so the physician cannot interact with the screen / interface without the risk of contamination. The physician may direct a colleague outside the sterile area regarding changes to the injection procedure, but this setup is inefficient and may lead to delays or errors during angiography, potentially endangering the patient's health. Furthermore, including the screen / user interface in a specific location may introduce risks associated with maintaining sterility in light of potential contamination of various fluid injector system components and associated devices.

[0052] All figures used in this specification and in the claims should be understood to be modified in all cases by the term “about.” The terms “approximately,” “about,” and “substantially” mean a range of plus or minus 10% of the stated value.

[0053] As used herein, the term "at least one of" is synonymous with "one or more of." For example, the phrase "at least one of A, B, and C" means any one of A, B, and C, or any combination of two or more of A, B, and C. For example, "at least one of A, B, and C" includes one or more A's, or one or more B's, or one or more C's, or one or more A's and one or more B's, or one or more A's and one or more C's, or one or more of all of A, B, and C. Similarly, as used herein, the term "at least two of" is synonymous with "two or more of." For example, the phrase "at least two of D, E, and F" means any combination of two or more of D, E, and F. For example, “at least two of D, E, and F” includes one or more of D and one or more of E, one or more of D and one or more of F, one or more of E and one or more of F, or one or more of all of D, E, and F.

Furthermore, the phrase “based on” is intended to mean “at least partially based on” unless specifically indicated otherwise.

[0055] When used in reference to components of a fluid infusion system, such as a fluid reservoir, syringe, or fluid line, the term “distal” refers to the part of the component closest to the patient. When used in reference to components of a fluid infusion system, such as a fluid reservoir, syringe, or fluid line, the term “proximal” refers to the part of the component closest to the injector of the fluid infusion system (i.e., the part of the component furthest from the patient). When used in reference to a syringe in a multi-patient disposable set, the term “proximal” refers to the part of the syringe closest to the piston for delivering fluid from the syringe. When used in reference to components of a fluid infusion system, such as a fluid reservoir, syringe, or fluid line, the term “upstream” refers to the direction of the fluid infusion system away from the patient towards the injector. When used in reference to components of a fluid infusion system, such as a fluid reservoir, syringe, or fluid line, the term “downstream” refers to the direction of the fluid infusion system away from the injector towards the patient.

[0056] As used herein, the terms “communicate” and “communicate” may refer to the reception, receipt, transmission, transfer, provision, etc., of information (e.g., data, signals, messages, instructions, commands, etc.). Communication between one unit (e.g., a device, a system, a component of a device or system, a combination thereof) and another unit means that one unit can directly or indirectly receive information from and / or transmit information to the other unit. This may refer to direct or indirect connections that are essentially wired and / or wireless. Furthermore, two units can communicate with each other even if the transmitted information is modified, processed, relayed, and / or routed between the first and second units. For example, the first unit can communicate with the second unit even if the first unit passively receives information and does not actively transmit information to the second unit. As another example, the first unit can communicate with the second unit if at least one intermediate unit (e.g., a third unit located between the first and second units) processes information received from the first unit and communicates the processed information to the second unit. In this embodiment, a message can refer to a network packet containing data (e.g., a data packet). It will be understood that many other configurations are possible.

[0057] According to various embodiments, fluid injector systems having a dual-display configuration offer advantages over conventional single-display injector configurations or conventional dual-display injector configurations. For example, a dual-display configuration allows access by users in a sterile area and users in a non-sterile area. As used herein, “sterile area” is defined as the area around an operating table or imager where a physician must remain in a sterile area and maintain the sterility of himself and various injector components to prevent the patient or injector components from being inadvertently exposed to microbial contamination when the patient is undergoing angiography or other medical procedure. As used herein, “non-sterile area” is defined as the area outside the sterile area where inadvertent contamination of various injector components is not a concern due to the distance between the non-sterile area and sterile components, sterile personnel, and the patient within the sterile area.

[0058] Embodiments of this disclosure generally relate to a fluid injector system which may include a main display device and an overlay display device. According to various embodiments, the main display device may be located inside the sterile area of ​​the angiography room or be movable inside the sterile area of ​​the angiography room, and may include a main user interface that provides control functions for the fluid injector. The overlay display device may be associated with the main display device or may be positioned in close proximity to the fluid injector of the fluid injector system. The overlay display device may be located outside the sterile area, and may include an overlay user interface that provides control functions for the fluid injector. The overlay user interface may include one or more elements that provide the same fluid injector control functions as one or more elements of the main user interface. In addition, according to certain embodiments, the main display device and / or the secondary display device may include one or more elements or functions that are available only on either the main display device or the secondary display device.

[0059] Thus, embodiments of the present disclosure relate to a dual-display fluid injector system in which the main display is located within a sterile area, for example, within a sterile area of ​​an angiography room, and the overlay display is located outside the sterile area, enabling easier, safer, and more accurate management of fluid injection procedures and medical imaging procedures simultaneously with the associated medical procedure. For example, the dual-display injector system described herein may be used during angiographic procedures such as the placement of a stent into a cardiac vessel, where the physician may be able to remain within a sterile area and perform and / or adjust various inputs associated with the contrast agent fluid injection procedure in real time during the angiographic procedure. The physician may perform the necessary adjustments or inputs on the sterile main display within the sterile area without potential contamination events.

[0060] This disclosure is generally described in relation to the pressurized infusion of medical fluids such as radiocontrasts and / or lavage agents in procedures such as angiography (CV), computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), X-ray, and positron emission tomography (PET). However, it should be understood that the devices, systems, and methods described herein may also be used in other applications where intravenous injection of medical fluids, therapeutics, pharmaceuticals, drugs, etc., is indicated. Furthermore, although this disclosure may apply to computed tomography (CT) and / or angiography type infusion systems, this description may also apply in the context of infusion systems designed for use in magnetic resonance (MR) imaging procedures. In particular, this disclosure is described herein, for example, in relation to dual-head (also known as dual-syringe) type systems, and it will be apparent that this disclosure may also be used in relation to single-head (also known as single-syringe) type infusion systems.

[0061] When performing an injection procedure, a fluid injector system may include a series of steps or processes for setting up the fluid injection procedure, priming and preparing the system for the fluid injection procedure, performing the fluid injection procedure, and preparing the system for subsequent fluid injection procedures. The series of steps or processes may be long and complex, and the possibility of skipping steps or inadvertently missing one or more steps may result in suboptimal images and potential harm to the patient, as well as / or the need to repeat the fluid injection and imaging procedure. Guided workflow procedures that guide the user through the injection procedure can improve the injection procedure and limit errors, resulting in improved image quality and limiting errors or potential harm to the patient. An example of a guided workflow procedure that may be performed by the fluid injector systems of this disclosure is described in Patent Document 1, the entire disclosure of which is incorporated herein by reference.

[0062] To perform a predetermined series of steps or processes, the fluid injector may include a display device or screen, such as a computer screen, tablet, or workstation device, for displaying various infusion procedure steps, commands, warnings, or other information regarding the progress of the infusion procedure or the fluid injector system. The display device may also include a user interface that communicates with and is associated with the fluid injector system's controller for managing and performing infusion procedure steps, entering or updating data, or controlling the functions of the fluid injector system. In some cases, the fluid injector may include a screen and / or interface associated with the fluid injector in an infusion chamber adjacent to the patient (e.g., within a sterile area), and / or a workstation device associated with the fluid injector system (e.g., outside a sterile area).

[0063] While referring to drawings in which similar reference numerals point to similar parts, the present disclosure generally relates to a medical injector / injection system 100 (hereinafter, "fluid injector system 100"), an injector system including one or more syringes, such as front-loading syringes and rolling diaphragm type syringes. However, the systems, components, devices, and protocols of the present disclosure may be used or incorporated into other syringe-based injector systems.

[0064] Referring here to Figure 1, non-limiting embodiments of the fluid injector system 100 and the fluid injector 102 (i.e., fluid injector head) associated with the fluid injector system 100 are shown according to the present disclosure. The fluid injector system 100 may include an electric injector management device or device configured to move various components of the injector during an injection protocol and operated by at least one controller or processor which may include an injection protocol management system, and a fluid delivery set intended to be associated with the electric injector to take up and deliver one or more fluids to a patient from one or more fluid reservoirs under pressure. In one example, the fluid injector 102 may include at least one fluid reservoir such as a syringe 140, at least one piston (not shown) having an interface reversibly connectable to the plunger of the syringe, and a fluid control module 132. Suitable embodiments and features of a syringe are described in Patent Document 2, filed August 10, 2021, the disclosure of which is incorporated herein by reference in its entirety. At least one syringe 140 may be adapted to be coupled with at least one component of the system, such as a syringe interface 134. The fluid injector 102 may be configured to deliver at least one fluid to a patient during an injection procedure, such as angiography injection. The fluid injector 102 may be configured to releasably receive at least one syringe 140 filled with at least one fluid, such as imaging contrast agent, saline, Ringer's lactate, or any desired medical fluid, supplied by a fluid source through a fluid line. The fluid injector 102 may be a multi-syringe injector, where two or more syringes 140 may be arranged side by side or in other spatial relationships and actuated separately by their respective pistons associated with the fluid injector 102. At least one syringe 140 may be oriented in any way, such as upright, down-right, or positioned at any angle.

[0065] Continuing to refer to Figure 1, the fluid injector 102 of the fluid injector system 100 is used during a medical procedure to inject at least one medical fluid into the patient's vascular system by driving a plunger of at least one syringe 140 with a drive member such as at least one piston (not shown). The at least one piston may be reciprocating relative to at least a portion of the at least one syringe 140, such as the plunger. When engaged, the at least one piston may move the plunger toward the distal end of the at least one syringe 140 and retract the plunger toward the proximal end of the at least one syringe 140. The syringe 140 may extend along its longitudinal axis. The fluid lines are also connected via fluid communication to the syringe tip of each syringe 140, and each syringe 140 is positioned in fluid communication with a bulk fluid reservoir, filling each syringe 140 with medical fluid and / or delivering fluid from each syringe 140 to the administration line, and also delivering fluid to a catheter (not shown) inserted into the patient at the vascular access site.

[0066] In various examples, the syringe holding mechanisms of this disclosure may be suitable for use in single or dual syringe type front-loading fluid injector systems, as disclosed in Patent Documents 3, 4, 5, 6, 7, 8, 9, 10, and 11, U.S. Patent Applications No. 15 / 305,285, 15 / 541,573, and 15 / 568,505, as well as in Patent Documents 12, 13, 14, and 15, which are incorporated herein by reference in their entirety.

[0067] Referring to Figure 1, the fluid injector 102 may include an injector housing 104 having opposing sides 106, a distal end or upper end 108, and a proximal end or lower end 110.

The overlay user interface 124 may be a graphical user interface (GUI) display window or a touchscreen, or it may include one or more elements 126 such as buttons and / or readouts. In embodiments where the overlay user interface 124 is a GUI, one or more elements 126 may be GUI elements. In some embodiments, the elements 126 of the overlay user interface 124 may be physical buttons. In some embodiments, elements such as the elements 126 associated with the user interface may provide control functions for the fluid injector 102 and / or the fluid injector system 100.

[0069] A user interface, such as an overlay user interface 124, may display information related to the fluid injection procedure, including the fluid injector system 100, such as the current flow rate, fluid pressure, and the volume remaining in the fluid source connected to the fluid injector system 100. In certain embodiments, the overlay user interface 124 may also be a touchscreen GUI that allows an operator to input commands and / or data for the operation of the fluid injector system 100. Although the user interface 124 is shown on the injector housing 104, the interface 124 may also be in the form of an additional remote display that is wired or wirelessly linked to the housing 104, as well as the electrical control devices and mechanical elements of the fluid injector system 100, or may include such a display. In some embodiments, the user interface 124 may be a tablet computer that is detachably connected to the housing 104 and links and communicates with the housing 104 wired or wirelessly. The fluid injector system 100 may further include one or more processors configured to electronically communicate with and control one or more functions of the fluid injector system 100.

[0070] In some non-limiting embodiments, element 126 may be provided as one or more control buttons (e.g., physical buttons or touchscreen buttons) for tactile operation by an attendant operator of the fluid injector system 100, such as buttons for engaging and disengaging the syringe holding mechanism described herein. In certain embodiments, element 126 may be part of a keyboard for the operator to enter commands and / or data. In some non-limiting embodiments, element 126 may be provided as a physical button in addition to one or more GUI elements provided to the overlay user interface 124. In such embodiments, element 126 may be wired or wirelessly connected to one or more electronic control devices associated with the fluid injector system 100 to provide direct input to one or more electronic control devices. Element 126 may provide the attendant operator of the fluid injector system 100 with specific individual control functions, including, but not limited to, (1) filling / purging / priming the fluid injector system 100, (2) inputting or manipulating patient and / or infusion procedure-related information and / or data, and (3) starting / stopping the infusion procedure. The overlay user interface 124 and / or any electronic processing units associated with the fluid injector system 100 may be connected by wire or wireless to an operating and / or data storage system such as a hospital information system. In some non-limiting embodiments, the fluid injector system 100 may include microphones, cameras, motion sensors, etc., for additional or alternative input of commands or information. In such embodiments, commands or information may be input via voice commands, gestures, etc.

[0071] Referring here to Figures 2A and 2B, non-limiting embodiments of the dual-display configuration of the fluid injector system 100 according to this disclosure are shown. Figure 2A shows an embodiment of the fluid injector system 100 including a fluid injector 102 having a fluid path cassette component engagement mechanism 202 having associated stopcock actuators and air detectors. Examples of suitable fluid path cassette components are described in Patent Document 16, the disclosure of which is incorporated herein by reference in its entirety. Figure 2B shows an embodiment of the injector system 100 including a fluid injector 102 having a dual syringe setting and associated syringe engagement mechanism, but without the associated fluid path cassette component engagement mechanism.

[0072] As shown in Figures 2A and 2B, the dual-display configuration of the fluid injector system 100 may include two display devices: a main display device 112 and an overlay display device 122. The fluid injector system 100 may also include two user interfaces: a main user interface 114 and an overlay user interface 124, which may be configured to communicate with and control the fluid injector 102. Each of the main display device 112 and the overlay display device 122, and / or the main user interface 114 and the overlay user interface 124, may include one or more elements, such as element 116, 126, which can be GUI elements or physical button elements as described herein. For example, the main user interface 114 of the main display device 112 may be a graphical user interface (GUI), and element 116 of the main user interface 114 may be a GUI element.

[0073] As shown in the exemplary embodiments of Figures 2A and 2B, the main display device 112 may be detachably mounted and positioned on an articulated arm 206, and the overlay display device 122 may be positioned on the housing 104 of the fluid injector 102. Furthermore, the fluid injector 102 and / or articulated arm 206 may be positioned on a stand 204. This configuration allows the main display device 112 to be positioned inside or located within the sterile area, while the overlay display device 122 positioned on the housing may be located outside the sterile area. In other embodiments, since the main display device 112 may be detachably mounted, the main display device 112 may be adaptable to be positioned inside or outside the sterile area. The configuration of a dual display configuration, including positioning the main display 112 and the secondary display 122, respectively, either inside or outside the sterile area, may depend on factors including field practice, physician / technician preferences, treatment parameters, and space constraints, but is not limited to these.

[0074] As described herein, each of the two display screens of the main display device 112 and the overlay display device 122 may include a main user interface 114 and an overlay user interface 124, respectively, either of which may be a graphical user interface (GUI) including a display window or touchscreen, and / or one or more buttons and readouts. The two user interfaces may independently or together display information about a fluid infusion procedure involving a fluid injector system, such as the current flow rate, fluid pressure, volume of fluid administered, and the amount remaining in the fluid source connected to the fluid injector system, as well as other data related to the fluid infusion procedure, such as patient data and a graphical display of the progress of the infusion procedure. In certain embodiments, one or both of the two user interfaces may be a touchscreen GUI that allows an operator to independently input commands and / or data for the operation of the fluid injector system via either of the two user interfaces. In certain embodiments, certain commands and / or data may be entered in only one of the two user interfaces, or in either of the two user interfaces. In various embodiments, inputs and / or data entered in one of the two user interfaces are observable and / or modifiable in the second of the two user interfaces.

[0075] Referring to Figure 3, a diagram of a non-limiting embodiment of an environment 300 in which the systems and devices associated with the fluid injector system 100 according to this disclosure may be implemented is shown. As shown in Figure 3, the environment 300 may include the fluid injector system 100, the injection protocol management system 302, the communication network 304, the hospital information system 306, the main display device 112, and the overlay display device 122. The fluid injector system 100, the injection protocol management system 302, the main display device 112, the overlay display device 122, and / or the hospital information system 306 may be interconnected via wired connections, wireless connections, or a combination of wired and wireless connections, for example, as shown in Figures 8, 11A, and 11B.

[0076] As shown in Figure 3, in certain embodiments, the injection protocol management system 302 may be an electronically controlled device and may include, or be operable to include, a processor that runs custom-designed or conventional software appropriate for executing and carrying out the processing steps of embodiments of the methods and systems of the present disclosure, thereby forming a specific computing system. Accordingly, the methods and systems currently disclosed may include one or more electronically controlled devices or similar computing devices having a computer-readable storage medium that can store computer-readable program code or instructions causing a processing unit to execute, configure or implement the methods, processes, and transformation data operations described below in relation to the present disclosure.

[0077] Continuing to refer to Figure 3, the infusion protocol management system may include one or more devices that can communicate with one or more of the fluid injector system 100, the main display device 112, the overlay display device 122, and / or the hospital information system 306 via the communication network 304. For example, the infusion protocol management system 302 may include one or more computing devices such as one or more computers, one or more controllers, one or more servers, one or more desktop computers, and one or more mobile devices. The infusion protocol management system 302 may include one or more software and / or hardware applications that perform a set of functions on an external application programming interface (API) that enables the infusion protocol management system 302 to send data to and receive data from external systems associated with the external API. In some embodiments, the application may be supported by an application associated with the fluid injector system 100, for example via the main display device 112 in a sterile area, which enables the infusion protocol management system 302 to be the sole device controlling the fluid injector system 100, in which case the infusion protocol management system 302 may provide authentication functionality. In some non-limiting embodiments, the injection protocol management system 302 may be a component of the fluid injector system 100, the main display device 112, and / or the overlay display device 122.

[0078] In some embodiments, the fluid injector system 100 may include one or more devices capable of communicating with an injection protocol management system 302, a main display device 112, an overlay display device 122, and / or a hospital information system 306 via a communication network 304. The fluid injector system 100 may include one or more fluid injection devices, such as a fluid injector 102, configured to administer an aqueous lavage fluid, such as saline, to a patient in order to administer a contrast agent to the patient, and / or before, during, and / or after administering the contrast agent. In embodiments, the fluid injector system 100 may include one or more exemplary fluid injector devices disclosed in Patent Documents 17, 18, 19, 20, 21, 22, 23, and 24, as well as Patent Documents 16 and 25, the disclosures of which are incorporated herein by reference in their entirety. In embodiments, the fluid injector system 100 described herein may be, or include components thereof, a Bayer MEDRAD® Stellant CT Injection System, a Bayer MEDRAD® Stellant FLEX CT Injection System, a Bayer MEDRAD® MRXperion MR Injection System, a Bayer MEDRAD® Mark 7 Arterion Injection System, a Bayer MEDRAD® Avanta Injection System, a Bayer MEDRAD® Intego PET Infusion System, a Bayer MEDRAD® Centargo CT Injection System, or any other Bayer source injector system used for angiography, magnetic resonance imaging, and computed tomography, all provided by Bayer Healthcare LLC. Various embodiments described herein may also be implemented with other commercially available fluid injector systems without departing from the scope of this disclosure.

[0079] In embodiments, the fluid injector system 100 may include one or more sensing mechanisms, such as one or more sensors, that enable the injection protocol management system 302 and / or the fluid injector system 100 to detect when a step in the guided workflow has started, progressed, and / or completed. The injector management system 102 and / or the fluid injector system 104 may notify the user of subsequent steps to be completed in the sequence of the guided workflow. One or more sensors may also be configured to determine whether a particular step in the guided workflow has been successfully completed before moving on to a subsequent step in the sequence of the guided workflow. If the injection protocol management system 302 and / or the fluid injector system 100 detects that a step has not been successfully completed or has been skipped, a warning notification may be provided to the main user interface 114 and / or the overlay user interface 124, for example, by the illumination of one or more warning lights (e.g., red light on or near a feature associated with a particular step) and / or one or more audible, visual, or tactile warning alerts, to indicate that the step was not completed correctly and the error must be corrected before the guided workflow can proceed to the next step. Similarly, in some non-limiting embodiments, one or more sensors may include switches, buttons, light sensors, motion sensors, accelerometers, air detectors, and the like. For example, an accelerometer may be implemented to detect changes in the orientation of the main display device 112 and / or the overlay display device 122, the movement of the articulated arm 206 and / or the stand 204, and / or other positioning of the fluid injector 102, for example, such changes in orientation may be associated with the execution or completion of a step in the guided workflow.

[0080] In embodiments, the main display device 112 and / or the overlay display device 122 may include one or more devices capable of communicating with the injection protocol management system 302, the fluid injector system 100, and / or the hospital information system 306 via the communication network 304. For example, the main display device 112 and / or the overlay display device 122 may include one or more computing devices such as computers, including desktop computers, laptops, tablets, etc. In certain embodiments, at least a portion of the processes performed via the main display device 112 and / or the overlay display device 122 may be performed on a remote server. The main display device 112 and / or the overlay display device 122 may provide user interfaces, such as a main user interface 114 and / or an overlay user interface 124, for controlling the operation of the fluid injector system 100, including generating commands for the fluid injector system 100 and / or providing commands to the fluid injector system 100. The main display device 112 and / or the overlay display device 122 may further display operating parameters of the fluid injector system 100 while the fluid injector system 100 is in operation (e.g., during real-time operation). In various embodiments, the main display device 112 and / or the overlay display device 122 may provide interconnectivity between the fluid injector system 100 and other devices or systems.For example, the main display device 112 and / or overlay display device 122 may include a computer monitor, touchscreen, head-up display, wireless handheld device (e.g., smartpad, smartwatch, smartphone, etc.) that can be used to display a user interface (e.g., a graphical user interface (GUI) of a software application) through which the user can interact to view parameters and / or control the operation of the fluid injector system 100 and / or imaging system.

[0081] Continuing to refer to Figure 3, the hospital information system 306 may include one or more devices that can communicate with the medical imaging system, the injection protocol management system 302, the fluid injector system 100, the main display device 112, and / or the overlay display device 122 via the communication network 304. The hospital information system 306 may include one or more subsystems such as a patient procedure tracking system (e.g., a system for operating modality worklists, a system for providing patient demographic information for fluid injection procedures and / or medical imaging procedures), a fluid injection management system, an image archiving and communication system (e.g., a picture archiving and communication system (PACS)), a radiology information system (RIS), and / or a radiology analysis system (e.g., Radimetrics® Enterprise Application, sold by Bayer HealthCare LLC). The hospital information system 306 may include one or more databases that store patient records that can be accessed by devices or systems within the environment 300.

[0082] The number and configuration of systems and / or devices shown in Figure 3 are provided as an example. Additional systems and / or devices, fewer systems and / or devices, different systems and / or devices, or systems and / or devices in a different arrangement than those shown in Figure 3 may exist.

[0083] Referring here to Figures 4A to 4E, diagrams of non-limiting embodiments of the fluid injector system 100 according to the present disclosure are shown. As shown in Figures 4A to 4E, the fluid injector system 100 may include a main display device 112, which may be located inside a sterile area. The main display device 112 may include a main user interface 114 that provides control functions for the fluid injector. Furthermore, an overlay display device 122 may be associated with the main display device 112, and they may be configured to communicate with each other.

[0084] In some embodiments, the fluid injector system 100 may be implemented in a “use case” where both the main display 112 and the overlay display 122 are used by non-sterile personnel in a non-sterile area. In such embodiments, the non-sterile user may input, adjust, or control the features and options available on each of the two display units without concern for contamination of the sterile area. For example, in a scenario during a fluid injection procedure, or before the first fluid injection procedure or after the last fluid injection procedure, the non-sterile user may input, change values, access results, or manipulate data or information on either of the two display units without potential contamination of the sterile area.

[0085] In some embodiments, the fluid injector system 100 may be implemented in “use cases” where one display, such as a main display device 112, is located within a sterile area, and the other display, such as an overlay display device 122, is located outside the sterile area. According to these embodiments, the display within the sterile area may be accessed and operated (e.g., inputting data values) by sterile personnel or physicians, for example, during angiography, while the display within the non-sterile area may be accessed and operated by non-sterile personnel or technicians / physicians. Sterile personnel are typically physicians assigned to perform injection procedures or injection protocols and angiography procedures on a patient's chair, such as inserting and manipulating catheters or guidewires into the patient's vascular system. During a procedure, a sterile physician may need to manipulate or input one or more injection parameters in real time, for example, by making slight adjustments to fluid pressure or flow rate, which may be done via the main display device 112 in the sterile area without concern for contamination of the sterile area. According to these embodiments, the dual-display configuration may be more convenient than instructing personnel outside the sterile area adjacent to the fluid injector 102 to make necessary adjustments. Non-sterile personnel may typically be technicians tasked with operating the fluid injector or adjusting injection protocol values ​​by directly inputting necessary information or numbers into a non-sterile display such as the overlay display 122, and may not necessarily be aware of real-time adjustments required for angiographic procedures in progress.

[0086] Therefore, in some non-limiting embodiments, the overlay display device 122 may be positioned close to the fluid injector of the fluid injector system or outside the sterile area. The overlay display device 122 may include an overlay user interface 124 that provides control functions for the fluid injector 102, and the overlay user interface 124 may include one or more elements 126 that provide the same control functions for the fluid injector 102 as one or more elements 116 of the main user interface 114. For example, as shown in Figures 4B to 4E, the overlay display 122 may be positioned on the head of the fluid injector 102, such as on the fluid injector head or housing (e.g., the housing 104 in Figure 1). In some non-limiting embodiments, for example, as shown in Figure 4A, the overlay display device may not be located on the fluid injector 102 but may be positioned adjacent to the fluid injector 102, for example, within a range of 0.5 to 5 feet of the fluid injector 102 associated with the fluid injector system 100, so as to be in the non-sterile area. In such non-limiting embodiments, the main display device 112 may be used by sterile personnel in a sterile area, and the overlay display device 122 may be used by non-sterile personnel in a non-sterile area. For example, the main display device 112 may be covered with a sterile sheath or other protective mechanism to maintain the sterility of the display, while the overlay display 122 may not be covered or otherwise protected to maintain the sterility of the injector mechanism.

[0087] In various embodiments, the dual-display configuration of the fluid injector system 100 prevents a non-sterile staff member in a non-sterile area from touching the main display 112 to instruct the injector to fill with more fluid, if the main display 112 is used in a sterile area and covered with a sterile sheath. Thus, the non-sterile overlay display 122 is configured for scenarios where a non-sterile staff member can operate and initiate a fluid injection protocol by operating the fluid injector via the overlay display 122 while the main display 112 is in a sterile area, allowing the sterile staff member to perform their work while paying attention to the patient and their needs during injection setup and procedures, such as inserting and manipulating a catheter or guidewire into the patient's vascular system. In other embodiments, the injector head of the fluid injector 102 may include a sterile sheath so that the overlay display 122 is in a sterile area and the main display 112 may be in a non-sterile area. In other embodiments, both the main display 112 and the overlay display 122 may be located within a sterile area, and their sterility may be maintained, for example, by a sterile sheath.

[0088] In various embodiments, the two displays may be configured to display options and features associated with the injection protocol and procedure, allowing relevant users to access them. In other cases, the two displays may be configured to display different values ​​available to the user of the other display, or to allow relevant users to operate them. For example, the main display 112 may be a display in a sterile area and may be operated by a physician or staff member performing angiography or other imaging procedure. The main display 112 in the sterile area may include, but is not limited to, a main user interface 114, such as a touchscreen mechanism, which allows sterile staff to access all options and features available on the injector, including adjusting injection protocol parameters, configuring injector settings, and visualizing fluid flow rates. The overlay display 122 may be a display in a non-sterile area and may be operated by a radiologist, technician, or other non-sterile staff member during angiography or other imaging procedure. The overlay display 122 may include, but is not limited to, a user interface 124 such as a touchscreen mechanism that allows the user to access tasks related to the fluid injector protocol, such as filling one or more syringes with contrast agent or saline wash, purging and priming the syringes and fluid pathway components before initiating the fluid infusion procedure, confirming the completion of the priming procedure to ensure that there is no air in the fluid pathway, preparing the injector to start once the syringes and fluid pathway are properly primed, and refilling the syringes if additional contrast agent or saline is needed during the patient procedure to complete the fluid infusion protocol. In certain embodiments, input or manipulation of certain parameters or injector settings may be restricted to either the main display 112 or the overlay display 122 only. For example, certain protocol parameters may be manipulated only by a physician in a sterile area via the main display 112, while other protocol parameters may be manipulated only by personnel in a non-sterile area via the overlay display 122.Other protocol parameters can be operated on either the main display 112 or the overlay display 122. In other embodiments, the ability to adjust specific infusion protocol parameters can be selectively locked out from either the main display 112 or the overlay display 122 during a procedure, for example, to prevent unintentional adjustment or modification of parameters. In certain embodiments, if a specific command is accessed on one screen to manually move the syringe piston, the automatic purge / automatic filling mechanism on the other screen can be locked out to prevent unsafe operation.

[0089] As further shown in Figure 4A, elements 126 of the overlay user interface 124 and elements 116 of the main user interface 114 may correspond to each other so that they provide the same control functions for the fluid injector 102 and the fluid injector system 100. Depending on the control functions presented or defined by one of the various steps of the guided workflow, both elements 126 of the overlay user interface 124 and elements 116 of the main user interface 114 may be enabled to provide the indicated control functions. In some non-limiting embodiments, as shown in Figure 4C, both elements 126 of the overlay user interface 124 and elements 116 of the main user interface 114 may be disabled with respect to control functions by being “grayed out,” covered (e.g., with diagonal lines as shown), or otherwise blocked. For example, if one or more sensors of the fluid injector system 100 detect that one or more components have been installed incorrectly, or that a series of steps in a guided workflow have been omitted or otherwise performed incorrectly, the lockout mechanism may disable both element 126 of the overlay user interface 124 and element 116 of the main user interface 114. Furthermore, the overlay display device 122 and / or the main display device 112 may provide an error message as described herein, and elements 116,126 may be disabled until the error is corrected.

[0090] As shown in Figure 4D, the overlay user interface 124 of the overlay display device 122 may include an element 126 which is disabled so as not to function with respect to the control function of the fluid injector 102. As further shown in Figure 4D, the main user interface 114 may include a main user interface element 116 corresponding to the disabled element 126 of the overlay user interface 124, and the main user interface element 116 may be enabled with respect to the control function of the fluid injector 102.

[0091] As shown in Figure 4E, the main user interface 114 of the main display device 112 may include an element 116 that is disabled so as not to function with respect to the control function of the fluid injector 102. As further shown in Figure 4E, the overlay user interface 124 may include an overlay user interface element 126 that corresponds to the disabled element 116 of the main user interface, and the overlay user interface element is enabled with respect to the control function of the fluid injector.

[0092] Referring here to Figures 5A and 5B, non-limiting embodiments of the main display device 112 and / or overlay display device 122, and the main user interface 114 and / or overlay user interface 124 of the fluid injector system are shown according to the present disclosure. As shown in Figures 5A and 5B, the main user interface 114 and / or overlay user interface 124 can be a graphical user interface (GUI). Furthermore, elements 116 of the main user interface 114 and / or elements 126 of the overlay user interface can be GUI elements.

[0093] In some non-limiting embodiments, as shown in Figure 5B, the main user interface 114 and / or overlay user interface 124 may include one or more elements 116',126' that may be physical buttons. In some non-limiting embodiments, as shown in Figure 5B, the main user interface 114 and / or overlay user interface 124 may include both physical button elements 116',126' and GUI elements 116,126. Implemented as physical buttons in exemplary embodiments, elements 116',126' of the main user interface 114 and / or overlay user interface 124 may also enable or disable the same or similar elements 116,126 of the main user interface 114 and / or overlay user interface 124, as described herein. For example, if the main display device is positioned in a sterile area and the overlay display device is positioned outside the sterile area, the button element 116' of the main display device 112 may be enabled to control the functions of the fluid injector 102 and the fluid injector system 100, such as preparing the fluid injector 102 to be activated when indicated by a guided workflow. However, this function may be provided only on the main display device, while the element 126' of the overlay user interface 124 in a non-sterile area may be disabled.

[0094] In some non-limiting embodiments, if the main user interface 114 and / or overlay user interface 124 include both physical button elements 116',126' and GUI elements 116,126, both physical button elements 126' and GUI elements 126 may be disabled with respect to the control functions of the fluid injector system 100. In other exemplary embodiments, the physical button element 126' may be enabled and the GUI element 126 may be disabled. The relationship between the main display device 112, the overlay display device 122, and the fluid injector 102, their positioning inside or outside a sterile area, the specific use case shown, and the steps or series of steps performed as provided by the guided workflow may, individually or in combination, determine which of the elements are enabled and which are disabled with respect to the control functions and / or data input associated with the fluid injector system 100.

[0095] Referring here to Figures 6A to 7F, Figures 6A to 6F illustrate non-limiting embodiments of the fluid injector system 100 in a first orientation according to the Disclosure, and Figures 7A to 7F illustrate non-limiting embodiments of the fluid injector system 100 in a second orientation according to the Disclosure. The exemplary first orientation can be an upright position or a set position, and the exemplary second orientation can be a downward position or an injection position. As shown in Figures 6A to 7F, the fluid injector system 100 may include various devices and components described herein, including a fluid injector 102, a main display device 112 that communicates with the fluid injector 102, and a main user interface 114 that can provide control functions. Furthermore, the fluid injector system 100 may include an overlay display device 122 that communicates with the fluid injector 102 and the main display device 112. The overlay display device may be positioned in close proximity to the fluid injector associated with the fluid injector system 102, and as shown in exemplary embodiments, the overlay display device may be positioned on the injector head of the fluid injector 102, which may be outside the sterile area. The overlay display device 122 may include an overlay user interface 124 that provides control functions for the fluid injector 102. In some non-limiting embodiments, the overlay user interface 124 may include one or more elements that provide the same control functions for the fluid injector 102 as one or more elements of the main user interface 114.

[0096] In some non-limiting embodiments, the fluid injector stem 100 may also include one or more syringes 140. As shown in Figures 6A to 6E, the fluid injector 102 and / or fluid injector system 100 may be configured in a first orientation with the proximal end of the syringe 140 facing upward. The main display device 112 may be detachably mounted on an articulated arm 206. The articulated arm 206 may allow the main display device to be moved to various positions within the sterile area as needed for injection procedures. The articulated arm may be positioned on a stand of the fluid injection system 100, such as the stand 204 shown in Figures 2A and 2B.

[0097] Continuing to refer to Figures 6A to 7F, in some embodiments, the fluid injector system 100 may include a mounting member 602. The mounting member 602 may be configured to allow the fluid injector system 100 to be mounted on a patient table 604, such as a self-supporting base or stand, or on a rail 606 of the patient table 604, as shown in Figures 6E to 6F and 7E to 7F. Thus, the articulated arm 206 may be positioned on the rail 606 of the patient table 604.

[0098] In some non-limiting embodiments, the overlay display device 122 may be detachably attached to a second articulated arm, and the articulated arm 206 of the main display device 112 and the second articulated arm of the overlay display device 122 may be attached to a common mounting point on the rail 606 of the patient table 604.

[0099] In some non-limiting embodiments, such as when the overlay display device 122 is provided on the fluid injector 102, the overlay display device 122 may include a sensor for detecting the orientation of the fluid injector 102, and the overlay display device 122 may be controlled or configured to adjust the orientation of numbers, words, and images on the overlay display device 122 based on the orientation of the fluid injector 102. In this way, the fluid injector system 100 ensures that the overlay user interface 124 is readable by the user regardless of the orientation of the fluid injector 102, and is displayed, for example, in an upright position. As described herein, the sensor for detecting orientation may be an accelerometer or another suitable sensor. The same or similar sensor may be provided on the main display device 112 to provide the same functionality.

[0100] For example, the fluid injector system 100 may be configured in a first orientation, as shown in Figures 6A to 6F, with the proximal ends of one or more syringes 140 facing upward to allow setting and priming of the syringe or other steps of the injection procedure. The fluid injector system may then be moved or repositioned as shown in Figures 7A to 7F, in which state the proximal ends of one or more syringes 140 are facing downward at the injection position. While or after the fluid injector 102 is being repositioned, sensors may detect changes in the movement and orientation of the fluid injector 102 and the overlay display device 122, and may correct the orientation of the overlay user interface 124 to ensure that the overlay user interface 124 is readable by the user and displayed in an upright position. When moving or repositioning the fluid injector system 100 from the first orientation to the second orientation, it is also possible to rotate the main display device 112 in the reverse or "upside down" orientation. By including the same or similar sensors in the main display device, changes in movement and / or orientation can be detected, and the orientation of the main user interface 114 can be corrected to ensure that the main user interface 114 is readable by the user and displayed in an upright position. In some non-limiting embodiments, one or more elements may also be provided to the user interface for manual input of changes in the orientation of the display device. In other embodiments, the user may lock the orientation of the information on the main display device and / or overlay display device to a desired position, for example, based on personal preference.

[0101] In some non-limiting embodiments, the main display device 112 may further include sensors such as accelerometers, mechanical switches, optical sensors, and motion sensors for detecting the joint angles of the articulated arm 206, or may communicate with sensors. The main display device 112 and the fluid injector system 100 may determine whether the main display device is inside or outside a sterile area based on the joint angles or orientation and position of the articulated arm 206. The same or similar sensors may be provided on the overlay display device 122 to provide the same functionality. Furthermore, once the positioning of the main display device 112 and the overlay display device 122 is determined in terms of which one or more display devices are inside and which one or more display devices are outside a sterile area, the fluid injector system 100 and each display device may initiate the execution of a guided workflow on their respective user interfaces. For example, if the main display device 112 determines that it is located inside the sterile area, the main user interface 114 may initiate a guided workflow for the display device located inside the sterile area. In embodiments where the main display device 112 determines that it is located outside the sterile area, the guided workflow for the display device located outside the sterile area may be initiated on the main user interface.

[0102] In some non-limiting embodiments, elements of the main user interface 114 for the main display device 112 and / or elements of the overlay user interface 124 for the overlay display device 122 may be provided for manual input of whether the display device is located inside or outside a sterile area. Manual input of whether the main display device 112 or the overlay display device 122 is located inside or outside a sterile area may initiate the execution of a guided workflow on the main user interface 114 or the overlay user interface 124 based on the manual input.

[0103] Referring here to Figure 8, non-limiting embodiments of an environment 800 in which a fluid injector system may be implemented are shown in accordance with this disclosure. As shown in Figure 8, the fluid injector system 100 may include one or more additional display devices, such as a secondary display device 812 that communicates with the fluid injector system 100 and the fluid injector 102. The secondary display device 812 may be provided in addition to the primary display device 112 and the overlay display device 122, or in place of either the primary display device 112 or the overlay display device 122. Furthermore, the secondary display device may be the same as or similar to the primary display device 112, which includes a primary user interface 114 having element 116, and / or the overlay display device 122, which includes an overlay user interface 124 having element 126. As previously stated in relation to the primary display 112 and the overlay display 122, certain functions and features may be associated with or disabled in accordance with the requirements of a particular fluid injection procedure.

[0104] As illustrated, the environment 800 may be a medical imaging room, such as an angiography room, which may be located in a hospital and / or imaging center for use when performing imaging procedures on a patient for diagnostic purposes and for interventionally treating vascular occlusion. The environment 800 may include, for example, a scanning room 808 within an angiography room, where a fluid injector system 100, a fluid injector 102, and a medical imaging system are located, and a control room 802 where an operator (e.g., a radiologist) can perform or monitor the injection and imaging procedures, monitor the angiography procedures, and monitor the patient via one or more sub-display devices 812, such as a workstation device associated with the fluid injection system 100 and / or the medical imaging system 806. The control room 802 may be separated from the scanning room 808 and therefore outside the sterile area. Furthermore, the control room 802 may be considered outside the sterile area and outside the non-sterile area due to the separation between the control room 802 and the scanning room 808. Therefore, the sub-display device 812 may be considered to be located outside the sterile area and outside the non-sterile area.

[0105] The fluid injector system 100 may include a multi-fluid delivery system, as described according to embodiments herein. As shown in Figure 8, the secondary display device 812 may communicate with an overlay display device 122 and / or a primary display device 112, which are used by an operator to set up and / or perform fluid injection procedures. In some non-limiting embodiments, the secondary display device 812 may provide a secondary user interface 814 (e.g., an application-based user interface, a web-based user interface, etc.) on the secondary display device for controlling the fluid injector system 100 and the medical imaging system 806. Parameters for the injection protocol of a fluid injection procedure may be entered by a user, retrieved from a common database, or automatically generated by a controller or injection protocol management system, such as the injection protocol management system 302 described herein associated with the fluid injector system 100, and in some embodiments, may be displayed on the secondary display device 812 and / or communicated to the fluid injector system 100 for execution.

[0106] The environment 800 may include a fluid injector system 100 having a fluid injector 102 mounted on a pedestal or stand 804 that has lockable casters fixed to the bottom, for use when moving the fluid injector system 100 within the scanning chamber 808 as needed during imaging procedures. The stand 804 may also include an integrated IV pole with one or more hooks for suspending IV-related accessories. In some non-limiting embodiments, the base may house various electronic and communication components, as well as a power supply for the fluid injector system 100. Alternatively, as described herein, the fluid injector 102 may be mounted on a patient table. As further shown in Figure 8 and also in Figures 11A-11B, the fluid injector system 100 may include, among other connections, a power cable 821 and an optical fiber link 822 that can communicate with a secondary display device 812 to enable control of the operation of the fluid injector system 100 from outside the scanning chamber 808. Other means of communication, including wireless communication via Wi-Fi, cellular, Bluetooth, and other similar networks, may also be implemented for communication between the sub-display device 812 and other components and devices of the fluid injector system 100. It is also conceivable that the sub-display device 812 may be located in an operating room, such as within the scanning room 808. In such non-limiting embodiments, the sub-display device 812 may be detachably mounted on an articulated arm positioned on a stand 804.

[0107] Referring here to Figures 9A and 9B, diagrams of non-limiting embodiments of the fluid injector system 100 according to the present disclosure are shown. As shown in Figures 9A and 9B, the fluid injector system 100 may include a main display device 112 that communicates with a fluid injector 102. The main display device 112 may be located inside a sterile area and may include a main user interface 114 that provides control functions for the fluid injector 102 and the fluid injector system 100. The fluid injector system 100 may further include an overlay display device 122 that communicates with the fluid injector system 100 and the main display device 112. The overlay display device 122 may be positioned close to the fluid injector 102 associated with the fluid injector system 100 and may be located inside a non-sterile area, as shown in Figure 9A. In some non-limiting embodiments, the overlay display device 122 may be positioned on a fluid injector 102 associated with a fluid injector system 100, as shown in Figure 9B, and may be located inside a non-sterile area.

[0108] The overlay display device 122 may include an overlay user interface 124 that provides control functions for the fluid injector 102 and the fluid injector system 100. The overlay user interface 124 may include one or more elements 126 that provide the same control functions for the fluid injector 102 and / or the fluid injector system 100 as one or more elements 116 of the main user interface 114. The fluid injector system 100 may further include a sub-display device 812 that communicates with the main display device 112 and the overlay display device 122. The sub-display device 812 may include a sub-user interface 814 that may be located outside the sterile area and may have one or more elements 816.

[0109] As further shown, the elements 816 of the secondary user interface 814, 126 of the overlay user interface 124, and 116 of the primary user interface 114 may correspond to each other so that they provide the same control functions for the fluid injector 102 and the fluid injector system 100. Depending on the control functions presented or defined by one of the various steps of the guided workflow, the elements 816 of the secondary user interface 814, 126 of the overlay user interface 124, and 116 of the primary user interface 114 may be enabled to provide the indicated control functions, as shown in Figure 9A. In some non-limiting embodiments, any combination of the elements 816, 126, 116 of each user interface may be disabled with respect to control functions by being “grayed out,” covered (e.g., with diagonal lines as shown), or otherwise blocked. For example, if one or more sensors of the fluid injector system 100 detect that one or more components have been installed incorrectly, or that a set of steps in a guided workflow have been omitted or otherwise performed incorrectly, the lockout mechanism may disable one or all of the respective user interface elements 816, 126, 116. Furthermore, any of the display devices 812, 122, 112 may provide an error message as described herein, and elements 816, 126, 116 may be disabled until the error is corrected.

[0110] In some non-limiting embodiments, as shown in Figure 9B, the sub-user interface 814 of the sub-display device 812 may include an element 816 that is disabled so as not to function with respect to the control functions of the fluid injector 102 and the fluid injector system 100. As further shown in Figure 9B, the main user interface 114 and the overlay user interface 824 may include a main user interface element 116 and an overlay user interface element 126 that correspond to the disabled element 816 of the sub-user interface, and the main user interface element 116 and / or the overlay user interface element 126 may be enabled with respect to the control functions of the fluid injector 102 and the fluid injector system 102. However, it should be understood that some elements may be disabled for a given user interface and / or may include other elements that are enabled with respect to control functions.

[0111] For example, the sub-user interface 814 may have elements that are disabled with respect to preparing the fluid injector to start up or executing or modifying the fluid injection protocol in real time, but may include one or more elements that are enabled to function with respect to inputting medical fluids or patient values ​​or information related to the injection procedure. Figure 10 shows an exemplary embodiment of a user interface as a GUI that enables input of medical fluids or patient values ​​or information related to the injection procedure, which may be a sub-user interface 814, a primary user interface 114, or an overlay user interface 124, each having user interface elements 816, 126, and 116, respectively.

[0112] In some non-limiting embodiments, one or more elements 116 of the main user interface and one or more elements 126 of the overlay user interface correspond to each other and are enabled with respect to the control functions of the fluid injector or fluid injector system, different or conflicting commands may be executed or different values ​​may be entered by different users via the main user interface 116 and the overlay user interface 126. In such cases, various lockout or override protocols may be implemented. For example, according to one embodiment, the first command or value entered is the command or value to be executed or used when performing the action. In some non-limiting embodiments, the second command or value entered overrides the first command or value, and therefore the second command or value entered is executed or used when performing the action. In other embodiments, if different or conflicting commands or values ​​are entered simultaneously or within a certain period (e.g., 1 to 5 seconds), the fluid injector system may perform a manual command-only lockout via the system's physical button-type elements, which may require the command to be re-entered or reset. Depending on the type of command or information being entered, various other lockout or override protocols may be implemented. In other embodiments, priority may be assigned to the input values ​​according to the user interface in which the values ​​are entered. For example, priority may be given to values ​​or inputs that are entered, for example, by a physician performing angiography via the main user interface 116. Such protocols may be stored in an injection protocol management system and executed by the fluid injector system when various predetermined conditions are met.

[0113] Referring here to Figures 11A and 11B, non-limiting embodiments of a secondary display device 812 and its components for a fluid injector system 100 according to the present disclosure are shown. As shown in Figures 11A and 11B, the secondary display device 812 may be a workstation device and may be located outside a sterile area such as a control room. The secondary display device 812 may include a secondary user interface 814 which may have one or more elements 816. The secondary display device 812 may further include one or more physical button elements 816' which may be provided on a handheld device and connected to the secondary display device 812 via wire 1022a. In some non-limiting embodiments, the physical button elements 816' may provide control functions relating to the fluid injector 102 and the fluid injector system 100.

[0114] As further shown in Figures 11A and 11B, the secondary display device 812 may communicate with a fluid injector system, such as the fluid injector system 100, via one or more connections. For example, an optical fiber link 822 provides network connectivity for the secondary display device 812 and the fluid injector system 100. In some embodiments, the secondary display device 812 may also be connected to the primary display device 112, the overlay display device 122, or another component or device of the fluid injector system 100 via wire 1022b. As described herein, the secondary display device 812 may also, or instead, be linked to, connected to, or communicate with the fluid injector system 100 or another device or component of the fluid injector system 100 via wireless communication such as Wi-Fi, cellular, Bluetooth, or other similar networks.

[0115] Some examples of fluid injector systems, devices, and related components of fluid injector systems having a dual display configuration are shown in the accompanying figures and described in detail above, but other embodiments will be obvious to those skilled in the art and can be easily made without departing from the scope and spirit of this disclosure. Therefore, the foregoing description is intended to be illustrative rather than restrictive. The various embodiments of this disclosure described above are defined by the accompanying claims, and all modifications to the disclosed concepts that fall within the same meaning and scope as the claims are included within those claims. While the above-described systems, methods, and various embodiments and aspects thereof are described in detail for illustrative purposes based on what is considered to be the most practical and preferred embodiments at present, such details are for that purpose only, and it should be understood that this disclosure is not limited to the embodiments or aspects described, but rather intended to cover modifications and equivalent configurations within the spirit and scope of this system. For example, it should be understood that this disclosure is intended to allow, wherever possible, one or more features of any embodiment or aspect to be combined with one or more features of any other embodiment or aspect. In fact, any of these features can be combined in ways not specifically disclosed herein. [Explanation of Symbols]
