[0092] There is a need for a balancing system for a tiltable or rotatable fluid injector system to ensure that the fluid injector system remains level or can be tilted or rotated at a desired speed. Some fluid injector systems are capable of rotating about an axis. This occurs for many reasons, such as the need to move a fluid injector system from a loading position to an injection position or the desire to move part of the system away from a patient after use. These are only two examples as there may be many other needs for such a system. A balancing system can beimplemented in this fluid injector system to prevent the system from rotating too quickly, which can cause damage to the system and components connected thereto, or to keep the system level.

[0093] Referring to FIGS. 1A-10, is an example of such a system 20. The injector balancing system 20 includes multiple other components, for example but not limited to, those described in U.S. Patent Nos. 10,124,110; 10,420,902; 10,888,651; 11,285,273; 11,351,306; 11,712,552; 11,839.751; 11,918,775; 11,938,093; 11.969,582; 11.998,718; 12,023,475; 12,023,464; 12.048.835; and 12,070.568: and PCT International Application / Publication Nos. WO 2022 / 265695; WO 2023 / 212177; WO 2023 / 215387; WO 2023 / 244580; WO 2024 / 086160; and PCT / US2024 / 025261, the disclosures of each of which are incorporated herein by this reference.

[0094] In FIGS. 1A-10. an injector balancing system 20 for use with a fluid injector system 10, according to embodiments of the present disclosure, is shown. With reference to FIGS. 1 and 2, the fluid injector system 10 includes a main body 12, an extension 14 that extends away from one end of the main body 12, and a support body 16 at the opposing end of the extension 14. The fluid injector system 10 can be connected to a support structure, such as a hospital bed B, operation table, IV-post, an arm connected to either, or another arm or device used to support the fluid injector system 10. In FIGS. 1 and 2, the fluid injector system 10 is shown connected to a hospital bed or surgical table, but the fluid injector system 10 can be connected to any support structure used within a medical environment. The main body 12 includes openings 18 that are used to receive syringes S or other medical components for use with the system 10. The syringes S operate to disperse fluid to be used with the injection system 10 via tubing (not shown) to a patient. As shown, two syringes S may be connected to the main body 12 via the openings 18, but it will be appreciated that any number of syringes S may be used with the fluid injector system 10. It will also be apparent that features described in this disclosure can be used in connection with injectors 10 that do not operate in exactly the manner described herein.

[0095] The fluid injector system fO has various components housed within the main body f2 to prime the tubing set, remove air from the tubing set, and disperse the fluid from the syringes S to a patient. The main body 12 also has a user interface UI to indicate to a user that the system 10 is ready for priming, dispersal of the fluid, replacement of one or more syringes S, or a repetition of any of these processes. The user interface UI may include buttons for a user to input commands to the fluid injector system 10 or be a touch screen to provide outputs to the user and receive inputs from the user. Other indications, inputs, and outputs may also bedone via the user interface UI. In certain embodiments a dual display user interface UI may be utilized, as described in International Application No. PCT / US2024 / 025261.

[0096] The support body 16 supports tubing or other components used with the fluid inj ector system 10. In one example, fluid may be dispersed, or unloaded, from the distal ends of the syringes S through one or more tubing components to the patient. In this example, the tubing and other equipment used to facilitate dispersal of the fluid can be supported by or connected to the support body 16 and / or extension 14. In another example, instead of syringes S. fluid containers may be held within the openings 18 and dispersed from the opposing end of the main body 12. The fluid containers may be connected to tubing to receive fluid via the ends of the containers not held within the main body 12. This tubing can be supported by or connected to the support body 16 and / or extension 14. The support body 16 may be used for other purposes not contemplated herein. While embodiments of the claimed balancing system may be illustrated and described using the syringe-based fluid injector illustrated in FIGS. 1A-10, the balancing system and various components described therewith may be utilized in other syringe- and non-syringe-based fluid injector systems, including systems utilizing peristaltic pump-based fluid delivery mechanisms or combinations of syringe- and peristaltic pump-based fluid delivery systems. Further, the balancing system and the various components may be utilized for balancing and aiding movement of other heavy and complex medical devices.

[0097] Other features may also be mounted to and pivoted about the fluid injector system 10. An example of one such feature is an auxiliary module 102. The auxiliary module 102 is arranged as a swingable arm configured to rotate about the fluid injector system 10, the features of which will be described below in connection with FIGS. 11-17G. The connection formed between the fluid injector system 10 and auxiliary module 102 will also be described below, but it will also be appreciated that this connection may be used with the fluid injector system 10 and other devices, not just the auxiliary module 102.

[0098] Referring to FIGS. 1A-10, anon-limiting embodiment of the fluid injector balancing system 20 will now be described. The injector balancing system 20 is arranged to allow for rotation of the fluid injector system 10 prior to, during, or after a fluid injection procedure, so that it can be easily moved from a loading position (shown in FIGS. 3A and 3B). where syringes S and other fluid path components may be connected and disconnected from the fluid fluid injector system 10 and the syringes may be filled with the appropriate medical fluid and various tubing components may be attached and primed with medical fluid, and an injection position (shown in FIGS. 5A and 5B and, in some examples, FIGS. 4A and 4B), where the contents of the syringes S can be dispensed and injected into a patient. However, the injectorbalancing system 20 may also be designed and configured to hold the fluid injector system 10 at the desired location. This is important with regards to the injection position, where it is best for the system to be arranged at a downward-facing angle relative to the horizontal to facilitate proper injection into a patient. To hold the fluid injector system 10 at a specific location and angled direction, the force from the weight W of the injection system 10 must be countered by another force, which will be described in greater detail below in connection with FIGS. 3A-6.

[0099] As illustrated in FIGS. 1A and IB, the injector balancing system 20 includes a support arm 22 extending from bed or table B. The support arm 22 is shown extending perpendicular to the bed or table B, but it should be understood that the support arm 22 may form other angles with the bed or table B and still allow for the proper use of the balancing system 10. A base arm 24 extends from the end of the support arm 22 opposite the bed or table B (see FIG. 2B). The base arm 24 is shown extending perpendicularly from the support arm 22 parallel to vertical length of the bed or table B, but the base arm 24 may form other angles with the support arm 22 and still allow for the proper use of the balancing system 20. In certain configurations, the base arm 24 may swivel relative to the support arm 22. The base arm 24 defines an internal space 25 and is arranged to form a hinge 26 with the fluid injector system 10. The hinge 26 defines a pivot point 28 about which the fluid injector system 10 rotates to reversibly move from the loading position to the injecting position. In some embodiments, the fluid injector system 10 also includes a mounting bracket 30 extending from the main body 12 and / or the extension 14 to help form the hinge 26. This mounting bracket 30 can be screwed or otherwise connected to the main body 12 and / or extension 14 of the fluid injector system 10. However, the mounting bracket 30 may also be formed integrally with the main body 12 and / or extension 14 of the fluid injector system 10.

[0100] The specific features of the hinge 26 are described in greater detail in connection with FIGS. 9 and 10. For the purposes of the balancing system 20, the mounting bracket 30 has a body 32 defining a first mounting region 34 and a second mounting region 36. Relative to each other, the first mounting region 34 extends beyond the second mounting region 36 within the body 32. Relative to the position of the mounting bracket 30 as applied on the fluid injector system 10. first mounting region 34 is generally located below the second mounting region 36.

[0101] As shown in FIGS. 9 and 10, the first mounting region 34 defines apertures 34A, 34B, and the second mounting region 36 defines apertures 40A, 40B. Apertures 34A and 40A are examples of first apertures of the first mounting portion 34 and the second mounting portion 36, respectively. Apertures 34B and 40B are examples of second apertures of the first mountingportion 34 and the second mounting portion, respectively. The end of the base arm 18 is arranged to be received within the first mounting region 34. The end of the base arm 18 defines apertures 42A, 42B. Aperture 42A is an example of a first aperture, and aperture 42B is an example of a second mounting aperture. Apertures 42A, 42B are aligned with the apertures 34A, 34B of the first mounting region 34. Among other things, a pin 44 is received within aperture 34A of the first mounting region 34 and aperture 42A of the base arm 18, and a shoulder bolt 46 is received within aperture 34B of the first mounting region 34 and aperture 42B of the base arm 18 to allow for rotation of the base arm 18 within the mounting bracket 30. The alignment of apertures 38A, 38B, 42A, 42B, pin 44, and shoulder bolt 46 form the pivot point 28. The second mounting region 36 further defines a space 48 between the apertures 40 A, 40B. A bolt 49 extends through apertures 42A, 42B. and the space 48. A first end 52 of a gas spring 50 is arranged to extend around and connect to the bolt 49, which will provide the balancing action on the fluid injector system 10. As used herein, “gas spring” means any spring mechanism including a gas damping system, such as an air spring. While air springs may be used in various embodiments herein, it is understood that other gases, such as nitrogen gas, argon gas, air, or other non-reactive gas. could be used without deviating from the scope of the disclosure.

[0102] Referring to FIGS. 3A-5B, the gas spring 50 is arranged primarily within the internal space 25 of the base arm 24, with the first end 52 extending into the first mounting region 34 of the mounting bracket 30. A second end 54 of the gas spring is secured to a bottom part of the base arm 24. The second end 54 may be considered a second end link. Between the first end 52 and the second end 54, is a cylinder 56 housing compressed air and a rod 58 displaceable within the cylinder 56. The rod 58 extends from the second end 54, and the cylinder 56 extends from the first end 52 of the gas spring 50. The gas spring 50 is connected to the base arm 24 and the bolt 49, so that the gas spring 50 can transmit a spring force SF against the bolt 49 via the compressed air. The spring force SF is the force that counteracts the weight W of the fluid injector system 10 to balance the fluid injector system 10. The gas spring 50 is adjustable, so that if additional force is applied to the cylinder 56 and / or rod 58, the cylinder 36 moves in the direction of the rod 58 or vice versa. When this happens, the rod 58 takes up space within the cylinder 56, and the air within the cylinder 56 is further compressed. This increases the pressure of the air within the cylinder 56, and the increase in pressure can be measured in an increase in the spring force SF acting against the bolt 49 and mounting bracket 30. Typically, this compression occurs when the fluid injector system 10 is rotated, applying a greater force to the cylinder 56 that leads to its compression against the rod 58. Asforce is removed from the gas spring 50, the cylinder 56 and rod 58 expand back to their original positions. It is through this mechanism that the fluid injector system 10 is balanced about the pivot point 28.

[0103] Referring to FIGS. 3A-6, the rotation and balancing of the fluid injector system 10 will now be described. FIGS. 3A-5B show the interactions between the fluid injector system 10 and injector balancing system 20 in a loading position (FIGS. 3A, 3B), a balanced horizontal position (FIGS. 4A, 4B) and an injection position (FIGS. 5A, 5B). FIG. 6 shows a force diagram of how the different forces created by the systems 10, 20 interact with the virtual arms of those forces being shown. The weight W of the fluid injector system 10 can be understood as acting straight downward at the center of mass (COM) of the fluid injector system 10. In FIGS. 3A-6, the center of mass (COM) is approximate and may be located in different places along the fluid injector system 10 depending on the weight distribution and arrangement of different features, such as the main body 12, syringes S, extension 14, and support body 18. In FIGS. 3A-6, the center of mass (COM) may be labeled in a certain location for clarity instead of for precise accuracy. The size of the main body 12 relative to the extension 14 places the center of mass (COM) on the side of the fluid injector system 10 having the main body 12. Given the rotation of the injector about the pivot point 28, the weight W will rotate the fluid injector system 10 downward, around the pivot point 28, depending on what side of the pivot point 28 the main body 12 and center of mass (COM) are located. In other words, the weight W of the fluid injector system 10 creates an injector moment IM about the pivot point 28, with a virtual injector moment arm IA (shown in FIG. 6) extending from the pivot point 28 to the center of mass (COM).

[0104] The spring force SF is arranged to counteract the weight W of the fluid injector system 10 and the injector moment IM created by the weight W. The spring force SF can either partially or completely offset the weight W and injector moment IM of the fluid injector system 10. In instances where the spring force SF only partially offsets the weight W, the fluid injector system 10 rotates about the pivot point 28 in the direction in which it is carried by its weight W. However, such a rotation will be slower than if the spring force SF were not present. In instances where the spring force SF completely offsets the weight W. the fluid injector system 10 is balanced at a desired location, such as the injection position. When balancing occurs, a user can still rotate the fluid injector system 10 as desired to change its position against the spring force SF. In this instance, in some embodiments, the gas spring 50 can be arranged to continue to balance the fluid injector system 10 after a user stops rotating the fluid injector system 10. In other embodiments, the gas spring 50 can be arranged to act against the weightW to move the fluid injector system 10 back to the balanced position after a user stops rotating the fluid injector system 10.

[0105] To perform these actions, the gas spring 50 is arranged to create a spring moment SM about the pivot point 28 that opposes the injector moment IM. The respective connections the fluid injector system 10 and the gas spring 50 have with the mounting bracket 30, means that the spring force SF can act against the weight W of the fluid injector system 10 if the gas spring 50 is on the same side of the pivot point 28 as the center of mass (COM) of the fluid injector system 10. In this context, the center of mass (COM) of the fluid injector system 10 and the gas spring 50 are on the same side of the pivot point 28 in the left-right direction when looking at FIGS. 3A-6. When this is the case, to counteract the injector moment IM, the spring force SF must have a virtual spring moment arm SA (shown in FIG. 6) such that the spring force SF multiplied by the distance of the virtual spring moment arm SA equals the weight W of the fluid injector system 10 multiplied by the distance of the virtual injector moment arm IA. SF x SA = W x IA. In this example, the spring force SF is arranged to balance the fluid injector system 10. In examples where the spring force SF only partially offsets the weight W of the injector, the spring force SF multiplied by the distance of the virtual spring moment arm SA is less than the weight W of the fluid injector system 10 multiplied by the distance of the virtual injector moment arm IA. SF x SA < W x IA. In examples where the spring force SF is greater than the weight W of the fluid injector system 10 in some places, the spring force SF multiplied by the distance of the virtual spring moment arm SA is greater than the weight W of the fluid injector system 10 multiplied by the distance of the virtual injector moment arm IA. SF x SA > W x IA. Thus, the amount of compressive force provided by the gas spring 50, the location of the first end 52 of the gas spring 50 relative to the pivot point 28 and the center of mass (COM) of the fluid injector system 10, and the weight W of the fluid injector system 10 must be selected with these performances in mind. The example discussed below may be modified and still lead to a balancing of the fluid injector system 10 with different arrangements given these parameters.

[0106] With reference to FIGS. 3A-5B, the rotation of the fluid injector system 10 and gas spring 50 are shown. First, in FIGS. 3A and 3B. the fluid injector system 10 is in a loading position, with the weight W of the fluid injector system 10 acting on one side of the pivot point 28 and the spring force SF acting on the same side of the pivot point 28 in a direction opposite that of the weight W. FIGS. 4A and 4B, show the fluid injector system 10 in a level position, which may be a loading position in some instances, depending on the needs of the patient. In this position, the weight W and spring force SF act in opposite directions, but both are arrangedover the pivot point 28. In this position, both the virtual injector moment arm I A and the virtual spring moment arm SM are zero. While the level position shows both the weight W and spring force SF acting without having a length for their respective moment arms IA, SA, the fluid injector system 10 can be placed in any intermediate position at a balanced position, with the weight W and spring force SF having a moment arm of some distance that results in their respective moments IM, SM being equal. FIGS. 5A and 5B show the fluid injector system 10 in an injecting position, with the main body 12 being angled below the horizontal. Here, the weight W and the spring force SF are again acting on the same side of the pivot point 28. This rotation of the fluid injector system 10 from the loading position to the injecting position, and vice versa, can lead to desirable outcomes for the fluid injector system 10, such as air bubbles being removed from the syringes S. For example, when the fluid injector system 10 is in the loading position air may gather at the distal end of the syringes S and may be removed by a priming operation. The rotational forces may also dislodge certain volumes of trapped air adhered to the sidewalls and plunger of the syringes S and urge them to the distal end for priming when in the loading position.

[0107] To ensure that the fluid injector system 10 does not rotate farther than the injection position, the gas spring 50 may have a spring force SF that overcomes the weight of the fluid injector system 10 when it is in the injection position or if the main body 12 extends farther below the horizontal than when the main body 12 is in the injecting position. To counteract the weight W, the gas spring 50 is arranged within the mounting bracket 30, so that the first end 52 rotates around the pivot point 28 as the fluid injector system 10 rotates. The first end 52 travels in an arc around the pivot point 28. To ensure that the fluid injector system 10 does not rotate farther than the injector position, a stop 29 may also be defined within the base arm 24 to prevent additional rotation of the gas spring 50 and / or the fluid injector system 10 relative to the base arm 24 and hinge 26. To define the stop, a slot 31 may be defined within the base arm 24. The slot 31 may receive the first end 52 of the gas spring 50. The slot 31 may also guide the first end 52 as it rotates in the arc about the pivot point 28. This may ensure that gas spring 50 imparts the spring force SF against the weight W at desired locations as the gas spring 50 rotates. The connection between fluid injector system 10 and gas spring 50 also means that slot 31 may guide the rotation of fluid injector system 10 to ensure that the weight W acts downward at desired locations. Stop 29 and slot 31 are shown in FIGS. 3B, 4B, and 5B.

[0108] To allow the first end 52 to travel in this manner, the second end 54 of the gas spring 50 is secured within the base arm 24 as shown in FIGS. 7 and 8. In particular, a cam 60 extends from the second end 54 and is supported by a support surface 62 extending from a sidewall ofand formed within the base arm 24. The cam 60 extends perpendicularly from the second end 54, but other arrangements may be used, so long as the functionality remains the same. The pressure of the compressed air and the shape and arrangement between the cam 60 and the support surface 62 helps to keep the cam 60 in place.

[0109] With continued reference to FIGS. 7 and 8, the pressure of the compressed air may be adjusted by moving the second end 54 of the gas spring 50 in the direction of the first end 52. This pushes the rod 58 into the cylinder 56 and forces more air compression. The support surface 62 is also shaped to define at least two support locations 62A, 62B. The first support location 62 A is where the second end 54 of the gas spring 50 is located a first distance away from the first end 52. This is a relaxed position. In this position, the gas spring 50 may be removed from the base arm 24 and mounting bracket 30 for maintenance. The second support location 62B is located above the first support location 62A and requires that the second end 54 of the gas spring 50 be moved in the direction of the first end 52, so that more of the rod 58 slides into the cylinder 56. This is the pre-loaded position. To move the second end 54 in either direction, a tool such as an Allen wrench (not shown) can be used to rotate a fastener 64 extending outward from the second end 54. Fastener 64 is connected to cam 60. so that rotation of the fastener 64 rotates the cam 60 upward from the first support surface 62A to the second support surface 62B. A slot 66 is defined in the sidewall of base arm 24 to allow access to fastener 64.

[0110] Referring still to FIGS. 7 and 8, to facilitate use of the cam 60, a mounting body 68 is arranged between the second end 54 of the gas spring 50 and the base arm 24 against a side of the base arm 24 that opposes the slot 66. The mounting body 68 defines a first aperture 70 and a second aperture 72. The base arm 24 defines an opening 74, and the second end 54 also defines an opening 75. The first aperture 70 of the mounting body 68 is arranged to be aligned with the opening 74 of the base arm 24, so that both receive a fastener 76. The connection formed by the fastener 76 between the aperture 70 and the opening 74 secures the mounting body 68 to the base arm 24. The second aperture 72 of the mounting body 68 is arranged to be aligned with the opening 75 of the second end 54. The cam 60 is received within both the second aperture 72 and the opening 75 to secure the cam 60 to the second end 54 and the mounting body 68. These connections allow the gas spring 50 to be moved within the base arm 24 while still being secured to the base arm 24. These connections also ensure that the rod 58 efficiently moves into and out of the cylinder 56 as the gas spring 50 is transitioned between the relaxed and preloaded positions. To facilitate this movement, the mounting body 68 may be shaped to rotate or move within the base arm 24 with the gas spring 50 to some degree.

[0111] Transition between the relaxed and pre-loaded positions allows for the spring force SF to be increased or decreased, depending on the parameters discussed above. Also, the spring force SF decreases over time, meaning that the gas spring 50 can be first used in the relaxed position and then later moved into the pre-loaded position, so that it can counteract the weight W of the fluid injector system 10 over a longer lifespan than if the gas spring 50 was only used in a single position within the base arm 28.

[0112] Another way to counteract the weight of the fluid injector system 10 is to apply a braking system 80 to the hinge 26 as shown in FIGS. 9 and 10. This braking system 80 can be used with the balancing system 20 or in place thereof. The features of the braking system 80 will now be described, with additional detail being provided as it relates to the hinge 26 and mounting bracket 30. As noted above, the pin 42 is received within the first aperture 34A that is defined in first mounting region 34 of the mounting bracket 30 and a first aperture 42A of the base arm 24. The shoulder bolt 46 is received within the second aperture 34B that is defined in the first mounting region 34 of the mounting bracket 30 and a second aperture 42B of the base arm 24. A frictional washer 82 is provided around the shoulder bolt 46 between the respective second apertures 34B. 42B of the first mounting region 34 and the base arm 24. The frictional washer 82 is arranged to create friction between the first mounting region 34 of the mounting bracket 30 and the base arm 24 to slow the rotation of the base arm 24 within the mounting bracket 30 or aid in holding the rotational position of the fluid injector systemlO. An end 46E of the shoulder bolt 46 is threaded and exposed within the second aperture 34B of the first mounting region 34 to allow for the shoulder bolt 46 to be tightened against the base arm 24. Similarly, a washer 84 is provided around the pin 44 between the respective first apertures 34A, 42A of the first mounting region 34 and the base arm 24. As shown, washer 84 is a normal washer, but washer 84 may also be a frictional washer that slows the rotation of the base arm 24 within the mounting bracket 30 or aid in holding the rotational position of the base arm 24 relative to the mounting bracket 30. Additional washers 86A, 86B are provided to fit around the threaded end of the shoulder bolt within the second aperture 38B of the first mounting region 34. First connecting pieces 88A, 88B are provided within the first apertures 34A, 42A, with a first connecting piece 88A being received within the first aperture 34A of the first mounting region 34 of the mounting bracket and a second connecting piece 88B being received within the first aperture 42A of the base arm 24. The pin 44 is arranged to be received within the first connecting pieces 88A, 88B. instead of directly contacting the first apertures 34A, 42A. A second connecting piece 90 is received within the second aperture 42B of the base arm 24. The shoulder bolt 46 is arranged to be received within the second connecting piece 90,instead of directly contacting the second aperture 42B. Finally, a nut 92 is arranged to be screwed onto the threaded end of the shoulder bolt 46 within the second aperture 38B.

[0113] As shown in FIG. 10, only the end 46E of the shoulder bolt 46 is threaded. However, one or more of the pieces discussed above in connection with the hinge 26 may be threaded to further facilitate connections between these features. For example, the outer surfaces of the first connecting pieces 88A, 88B may be threaded to interact with corresponding threads defined within the first apertures 34A. 42A. In other examples, the outer surface of the pin 44 and inner surfaces of the first connecting pieces 88A, 88B may be threaded to form a connection therebetween. The outer surface of the second connecting piece 90 and the inner surface of the second aperture 42B may also be threaded. In even more examples, the connecting pieces 88A, 88B, 90 may be omitted, and the pin 44 and shoulder bolt 46 may directly contact their respective apertures in a threaded or unthreaded manner.

[0114] With reference to FIGS. 11-18G, embodiments of a module pivoting system 100 according to the present disclosure are shown. The module pivoting system 100 may be used by itself or in combination with any of the systems discussed herein. The module pivoting system 100 is arranged allow rotation of an auxiliary module 102 around the fluid injector system 10. The auxiliary module 102 may include containers, such as bottles, vials and / or bags of medical fluid such as contrast media, saline or other fluids that are used in connection with an injection procedure performed using fluid injector system 10. The auxiliary module 102 may also include electronics or other features to help use the fluid injector system 10. For example, in one embodiment, the auxiliary module 102 may include a second screen that may be within or outside of the sterile field during an angiography procedure, as described in International Application No. PCT / US2024 / 025261, and may be pivoted into or out of the sterile field as necessary. The auxiliary module 102 is arranged to pivot from a first position, on one side of the fluid injector system 10 to a second position located on an opposing side of the fluid injector system 10 or anywhere in between. The pivoting is such that the same face of the auxiliary7module 102 is visible on both sides of the fluid injector system 10.

[0115] With reference to FIGS. 11-16, a linkage 104 connects the fluid injector system 10 to the auxiliary module 102. The linkage 104 is made up of a connecting bar 105 and a housing 134 that covers the connecting bar 105. To better see the connections made with the connecting bar 105, the housing 134 is omitted from FIG. 14. As shown, the connecting bar 105 forms the physical connections of the linkage 104, and the housing 134 covers the connecting bar 105. However, in other embodiments, the housing 134 may also form physical connections of thelinkage 104. One will understand how other features may be modified to accommodate the housing 134 when it forms these physical connections.

[0116] The fluid injector system 10 has a first connector 106 that includes a base 108 extending from an outer surface of the base arm 24. The fluid injector system 10 and injector balancing system 20 are arranged, so that the pivot point 28 is located above the base 108, however other location sites on the fluid injector system 10 are considered to be within the present disclosure. The base 108 has a top portion 110 and a bottom portion 112 defining a space 114 therebetween. A cylindrical body 118 extends from the bottom portion 112, and the connecting bar 105 is secured to the cylindrical body 118. A pivot pin 120 is used to secure the connecting bar 105 to the cylindrical body 118, but other fasteners or connection methods may be used. The auxiliary module 102 has a second connector 122 that includes a tube 124 received within the auxiliary module 102. The tube 124 is rotatable within the auxiliary module 102 to allow- for its rotation, which will be discussed below . The tube 124 defines a hoi low cavity 126, so that a pivot block 128 can be mounted to the tube 124 within the hollow cavity 126. As shown, the pivot block 128 may a curved or crescent shape so that it does not occupy the entire surface area defined by the hollow cavity 126. Other shapes may be used to allow for the pivot block 128, tube 124, and linkage 104 to operate as described herein. The connecting bar 105 is mounted to the pivot block 128, so a receiving slot 130 is formed in a sidewall of the tube 124, to allow for this connection. Another pivot pin 132 is used to secure the connecting bar to the pivot block 128, but other connections may be used.

[0117] A housing 134 extends around and covers the connecting bar 105 and portions of the first and second connectors 106, 122. A space 136 is formed within the housing 134 to hold the linkage 104, and the space 136 extends between a first end 138 and a second end 140. The first end 138 engages with the first connector 106 and includes a cylindrical portion that fits about the cylindrical body 118 and rests on the bottom portion 112. An opposing end contacts and / or may wrap around part of the top portion 110. The second end 140 engages with the second connector 122 and also has a generally cylindrical portion that fits around the tube 124 that extends beyond the auxiliary module 102. Other sidewalls fill in the space around the space 136, first end 138, and second end 140, so that the connecting bar 105 is not exposed.

[0118] Cylindrical body 1 18 defines a first longitudinal axis LI, and tube 124 defines a second longitudinal axis L2. The connecting bar 105 is connected to the cylindrical body 118 and pivot block 128, so that the ends of the connecting bar 105 are secured to the respective pieces are offset from both longitudinal axes LI, L2. These offsets allow for the auxiliary module 102 to pivot about the fluid injector system 10 in a desired manner, so that the auxiliarymodule 102 can be viewed and operated in substantially the same way in the first position as the second position.

[0119] Referring to FIGS. 18A-18G, the rotation of the auxiliary module 102 with the module pivoting system 100 will now be described. These descriptions are exemplary, and one will understand that modifications of different features, such as lengths and relative angles can change the operation of the module pivoting system 100 within the spirit of the disclosure.

[0120] In a first position shown in FIG. 18A. a face 130 of auxiliary module 102 may be angled at up to 90 degrees from a virtual perpendicular line P extending through a center point of the auxiliary module 102. In particular embodiment, a face 130 of auxiliary module 102 may be angled at up to 50 degrees from a virtual perpendicular line P This angle and the perpendicular P are shown throughout the figures. In a second position shown in FIG. 17G, the face 130 of the auxiliary module 102 may be angled at 50 degrees from the same perpendicular P in the opposite direction. In other words, the face 130 is angled at -50 degrees relative to the perpendicular P. Thus, the face of the auxiliary module may be angled from 50 degrees to -50 degrees relative to the perpendicular P, or any angle relative to the perpendicular P. For purposes of illustration, if the fluid injector system 10 is viewed as a reflective plane, the auxiliary module 102 appears in the second position as a mirror image of itself when it is in the first position. In other words, the arrangement of the auxiliary module 102 “flips” from the first position to the second position as it rotates about the connection formed between the connecting bar 105 and the cylindrical body 118. During the rotation, the auxiliary module 102 is rotated 200 degrees about the connection between the connecting bar 105 and the cylindrical body 118. The intermediate positions, highlighting the transition of the auxiliary module 102 from the first position to the second position are shown in FIGS. 18B-18F. As the connecting bar 105 rotates about its connection to the cylindrical body 118, the corresponding offsets work to rotate the auxiliary module 102, so that its face 130 is in the desired position when it reaches the second position. As shown, when moving from the first position (FIG. 18A) to the second position (FIG. 18G), the offset of the linkage 104 with respect to the first longitudinal axis LI “pulls” the auxiliary module 102 closer to the connection formed between the connecting bar 105 and the cylindrical body 118. When moving from the second position back to the first position, that offset “pushes” the auxiliary module 102 away.

[0121] Depending on how the auxiliary module is intended to be viewed and used relative to the fluid injector system 10, the shapes, sizes, and arrangements of the different elements of the module pivoting system 100 can be changed to obtain a desired result. In other words, the features of the module pivoting system 100 can be manipulated to change the arrangement ofthe auxiliary module 102 in both the first and second positions as well as any intermediate positions. For example, different features that may be modified can be: (1) the location and distances of the offsets formed between the linkage 104 and the longitudinal axes LI, L2; (2) the length of the linkage 104; (3) the arrangement of the pivot block 128 within the hollow cavity' 126; and (4) the degree of rotation of the linkage 104.

[0122] While specific embodiments of the devices of the present disclosure have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the device of the present disclosure which is to be given the full breadth of the claims appended and any and all equivalents thereof.
