Description

[Technical Field]

[0001] This application claims the benefit of priority to U.S. Provisional Patent Application No. 62 / 238,358, filed October 7, 2015, and U.S. Provisional Patent Application No. 62 / 336,571, filed May 13, 2016, the disclosures of which are incorporated herein by reference in their entireties.

[0002] The present disclosure relates generally to the field of medical devices with peripheral modules, including systems, instruments, related accessories, and components, that involve the transmission of data, fluid, and energy through various cables, cords, wires, and / or conduits.

[0003] More particularly, the present disclosure may relate to extracorporeal fluid support and transport systems such as perfusion systems, also known as "heart-lung" machines and cardiopulmonary bypass machines. [Background technology]

[0004] There is an ever-increasing need for new and improved solutions for medical devices that utilize several different electronic and / or motorized modules, particularly those that require rearrangement with, replacement with, addition to, or removal from the main console machine during use in a surgical setting, whether in a planned or unplanned manner. Some of the modules may have direct physical and electrical connections to the main console, while others may be indirectly attached by wires and cables and be remotely powered or controlled. Within the field of cardiopulmonary perfusion, rearrangement of modules to the primary chassis and frame of a heart-lung machine may need to occur prior to and during use of such a machine. During a surgical procedure, if the need arises during use that requires a change in the arrangement of components or the use of certain components, such interruptions can be inconvenient, add extra time and cost to the overall surgical procedure, and complicate the delivery of care to the patient. With highly specialized procedures, such as on-pump CABG surgical procedures, such interruptions are particularly undesirable for the surgical team involved in the CABG procedure.

[0005] Perfusion systems involve a variety of components and accessories that depend on the patient's needs, the operator's preferences for operational settings, the availability of modular hardware (e.g., console pumps, mast-mounted pumps, pump displays, and controllers, etc.), and the use of various sensors and diagnostic equipment. Prior to performing a cardiac surgical procedure, a perfusionist may configure the equipment in one of a wide number of permutations intended to address the needs of the patient who will undergo the surgical procedure. Due to the extensive use of cables, blood conduits, pumps, pump displays, and other related devices commonly involved in such procedures, cables and cords can become highly tangled and difficult to manage. This can lead to specific problems of operational inconvenience and time inefficiency for the perfusionist.

[0006] Because heart-lung machines often involve the use of various peripheral modules that must be controlled through the heart-lung machine's user interface, and given that any one of the peripherals may need to be replaced or replaced for a variety of reasons, including, but not limited to, a change in therapy delivery or an unexpected failure of the unit (whether electrical or mechanical), the peripherals need to be quickly interchangeable so that a perfusionist can be present to deliver cardiac support to the patient and minimize any downtime associated with the failure. Additional complications can arise when peripherals cannot be quickly replaced due to the routing of cables and wires. Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, there is a need for medical devices, such as heart-lung machines, with improved features that allow users to simplify reconfiguration, setup, and management of their systems. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0038] Various embodiments according to the present disclosure will be described with reference to the drawings, in which like parts are designated by like reference numerals. The drawings described herein constitute non-limiting illustrations. For purposes of explanation, hereafter, the words “upper,” “lower,” “right,” “left,” “vertical,” “horizontal,” “top,” “bottom,” “lateral,” “longitudinal,” “axial,” and similar terms, when used, shall refer to the invention as oriented in the drawings. Where appropriate, the term “patient side” shall refer to the side of the device that typically faces (or is otherwise closest or most proximal to) a patient, such as a patient undergoing a cardiac surgical procedure in an operating room. The terms “operator side” or “perfusionist side” shall refer to the side of the device that typically faces an operator of the device, generally opposite the “patient side,” as would be found in the case of a perfusionist managing the operation of a heart-lung machine in an operating room. It should be understood that the present invention may take on many alternative variations and embodiments, unless expressly specified otherwise. It is also to be understood that the specific devices and embodiments illustrated in the accompanying drawings, and described herein are simply exemplary embodiments of the present disclosure.

[0039] 1A through 5 illustrate a console 8 of a medical device system 10, and more particularly, by way of example, the device system 10 configured as a medical bypass machine, such as a cardiopulmonary machine (i.e., a cardiopulmonary bypass machine). However, the medical device system can additionally or alternatively be configured as a machine useful for extracorporeal fluid transfer and therapy, such as any of a cardiac assist, cardiac bypass, extracorporeal membrane oxygenation (ECMO), apheresis, or dialysis type machine.

[0040] The medical device system 10 includes a console 8, illustrated in FIG. 1A as having a base 12 (or base portion / chassis) and a frame 14 (or frame portion) connected to and generally mounted on top of the base 12. The base 12 may further house or support electrical components, cable connection ports, processors, batteries, power converters, and controllers useful for controlling, capturing data from, and managing power, machine instructions, and energy delivery to one or more modules. Examples of such modules include one or more console pumps 16, illustrated in FIG. 1A as either individual pump modules 16a or twin-pump console modules 16b, shown resting on a console pump module support surface 96. The two types of pump modules 16 each have one or more roller pump heads 18 with raceways for receiving one or more cardiopulmonary circuit tubing. The console pump module 16 further includes an integrated display 20 and one or more controls 22 for controlling its individual pump speed and the resulting flow rate of fluid transmitted through the tubing connected to the pump. As shown in FIG. 1A, the pump modules 16 are arranged in a "piano" configuration, with adjacent pump modules arranged in a generally parallel orientation relative to adjacent console pump modules. This pattern may utilize two or more (preferably, three to five) pump modules in a row. Non-pump console modules, such as storage containers 24, having handles 26 for opening and closing the container drawers and mountable to the console base in a manner similar to how the console modules are mounted, may also be utilized.

[0041] The display 20 for the console pump is generally oriented so as to be viewable from the "operator side" 28 of the console 8 and opposite the "patient side" 30 (see FIG. 2). The console pump may be controlled directly by the operator or through the primary module display 6 (see FIG. 1), so long as the display 6 includes control functionality, which may be implemented, for example, via a touch screen interface. The console 8 is shown in the figures as having multiple masts 52 extending vertically from a frame support surface 50 to shelves 62. The masts 52 are generally fixed relative to the frame and support surface 50 and are useful for directly or indirectly mounting various peripheral accessories thereto, such as a mast-mounted pump 170.

[0042] 1A, the fixed masts 52 are arranged as two front masts 54 and two rear masts 56, with the front masts 54 terminating at and supporting the bottom of the elevating shelf 62, while the rear mast 56 connects to and extends vertically through the shelf 62 and includes an IV pole top with multiple IV hooks. There may also be one or more auxiliary masts 242 extending from the rear mast 56 via one or more mast extensions or booms 244. The versatility afforded by having additional masts provides the operator with a seamless and unlimited amount of arrangement in which additional peripheral devices, such as pumps, can be included within the operating configuration of the medical device when configured as a heart-lung machine.

[0043] In addition to using a mast to mount certain peripheral devices, certain devices may be conveniently located on additional work surface areas such as the upper shelf 62 or the removable shelf 240. The removable shelf 240 is shown in FIG. 1 as being reversibly mounted to one of the upper or lower rails, and by way of example, is shown in FIG. 1 as being attached to the base rail 88, as described in more detail below.

[0044] Located vertically above the console pump 16 is a shelf 62, which is shown having a generally flat upper surface 64 with upwardly oriented edges on its back and side sides and a downwardly oriented edge on its front side (i.e., operator side). Attached to the edges are a plurality (i.e., a first upper set) of rails that surround the periphery of the shelf 62. Four rails are shown, but more or fewer rails may be used. The rails may have any type of cross-sectional shape, such as square, circular, oval, elliptical, rectangular, etc., and preferably have a generally rectangular cross-sectional shape. More specifically, the shelf 62 is shown with two upper rails 78, 80, one back rail 76, and one front rail 74. The front rail is shown to be at an elevation below the top surface 64 of the shelf 62, while the side and back rails are shown to be slightly raised or at the same elevation as the top surface 64 of the shelf.

[0045] A second (i.e., lower) set of rails is shown attached to frame support surface 50. Three rails are shown: two side rails 86, 88 and one rear rail 84, spaced around the side and rear edges, respectively, of frame support surface 50. Optionally, the rails may be bent at their ends to conform to the corners and perimeter of frame support surface 50 and shelf 64, while in other areas, the rails are generally straight.

[0046] FIG. 2 illustrates the patient side of the console 8. Extending generally vertically between the shelf 62 and the frame support surface are a movable mast 92 and cable chases 100, 136. The cable chases 100, 136 and movable mast 92 may be reversibly or irreversibly secured to the console 8 through connections with one or both of an upper set of rails and a lower set of rails. The connections may be lockable so that either or both of the movable mast 92 and cable chases 100, 136 may be restricted (fully, partially, or selectively) from horizontal lateral movement (indicated by arrow 94 in FIG. 4 ) along the length of the rails (e.g., along the patient side 30) that would otherwise be possible without the locking.

[0047] The cable chases 100, 136 are shown in FIG. 2 as having one or more chase openings 112 so that cables / cords / tubes, etc., can enter and exit the cable chase at different elevations relative to the console 8. For example, opening 112a may be located toward the top of the cable chase / raceway 100, 136, providing access to cables located above or below the shelf 62. In another embodiment, opening 112b may be located toward the bottom of the cable chase, providing access to cables exiting the base 12 of the console 8. Additional openings (112c, 112d) may be present between the top and bottom portions of the cable chase. While the openings are shown located on the sides of the cable chase, they may alternatively and / or interchangeably be located at the upper and lower ends of the cable chase or along different sidewall portions of the cable chase.

[0048] 5 illustrates another view of the patient side of the console 8, including upper and lower boundaries 600, 602, and detailed views 6A and 6B provide a close-up view of exemplary means for connecting the cable chases 100, 136 to the rear shelf rail and rear base rail, respectively. As a specific example, the connection means is shown to be a mechanical clamp, such as a C-clamp. It is understood that other methods of connecting the cable chases to the console can, of course, be used, including C-clamps, which may be adjustable or constructed using flexible compliant materials.

[0049] FIG. 7 illustrates a perspective view of a cable chase 100, while FIG. 8 illustrates a side view of the embodiment of FIG. 7. In the exemplary embodiment, the cable chase has a top end 104 and a bottom end 106 and a chase body or housing 108 extending therebetween, which provides an interior chase raceway (or channel) 102 that provides a partially or completely enclosed space along which cables, cords, tubing, and the like may extend. The ends of the cable chase are shown as closed but may alternatively be open. Also shown in FIG. 7 is an optional chase cover 110. In some embodiments, the chase cover 110 fits over the housing portion 108 and may further enclose the chase raceway 102 and confine cords / cables / conduit-like structures routed through the cable chase (see FIG. 9B for a cross-sectional view of the raceway area taken along section line 9B-9B of FIG. 8). A cover may also be used to enclose the open side of the opening 112(a, b, c). In various embodiments, the cover 110 may be attached along a vertical / longitudinal edge of the chase body by a hinge acting as a door, while in other embodiments the cover may be attachable to the chase body 108 by one or more reversible connection mechanisms, including, but not limited to, the use of clamps, hook and loop (VELCRO) surfaces, latches, screws, knobs, pins, etc.

While various means of attaching the cover to the chase body 108 are also contemplated, a particularly useful embodiment involves utilizing angled, upwardly opening slots on one of the cover 110 or body 108 and a set of guide pins 116 on the other of the cover or body. Once aligned, the pins 116 can slide into the slots 114 and, under gravity, retain the cover 110 against the body 108. Additionally, a post 133 may be located on the top end of the chase body 108 and engage a threaded knob 132 to help retain the cover 110 against the chase body 108. As best shown in FIG. 12, a C-shaped clamp may be connected to the chase body 108 by various means, such as the use of screws or adhesive. Alternatively, the C-shaped clamp structure can be integrally formed with the chase body 108 .

[0053] FIGS. 14-15 illustrate an embodiment of a cable chase 136 having certain improvements over the previously described embodiments. FIG. 14B is a detailed view taken with respect to the boundary 608 of FIG. 14A , showing a latch or hook 138 located at the top end of the chase cover 148. FIG. 14B differs from FIG. 14A in that a cross section of the rail 76 is shown, with sufficient clearance and throat for the hook 138 to be suspended on the rail 76. The hook 138 may be configured as one or more hooks and can further be used to aid in connecting the cover 148 to the chase body 146, at least in part, via insertion of an end of the hook into one or more slots 144 located in the chase body 146. As with the embodiment of FIGS. 5-13 , a mechanical fastening mechanism, such as a threaded screw knob, can be used to further secure the cover 148 to the chase body 146. Also, while the embodiment of Figures 5-13 illustrates three openings 112, a fourth opening 112d may also be employed in any of the cable chase embodiments described herein, as more clearly shown in Figure 14A.

[0054] 16-20 illustrate additional features of the present disclosure that may be employed with or without the cable chase embodiments 100, 136 described herein. For example, FIG. 16 illustrates a top view of the cable holder 200, while FIG. 17 shows the cable holder 200 in a front perspective view, with other structure of the console 8 not shown. The holder 200 is shown with a base portion 214 formed as a shallow U-shaped channel 202 and interposed between two leg portions 216. The base portion may have a width substantially greater than the height of the leg portions. The holder 200 may include a plurality of cutouts 206 that are extensions and are formed in the leg sections 216, establishing a plurality of fingers 204. From one longitudinal edge of the holder 200 to the other, the fingers 204 can form one or more passages, such as a first passage 210 and a second passage 212, as shown in FIG. 16. The cable holder 200 may be secured to the shelf 62 in a suspended manner, as shown in FIGS. 18A, 18B, 19, and 20. One or more standoffs 222, such as shoulder bolts, may be used to accomplish this. In an alternative embodiment, the shelf may be attached to one or more of the masts and extend directly below the shelf 62 (such as in a cantilevered manner). An optional feature in all of the shelf embodiments disclosed herein is the use of shelf openings or shelf channels 68, which provide convenience in routing cables through the shelf instead of, or if needed, in addition to, routing them around the perimeter of the shelf.

[0055] 19-21 depict non-limiting examples of cable holders 200 for use with cable chases 100, 136. The peripherals used in the disclosed embodiments may include an auxiliary display 232 used to monitor and control a mast-mounted pump 170. FIG. 19 shows the auxiliary display 232 mounted to the shelf front rail 74 and the mast-mounted pump 170 attached to one of the vertical masts (e.g., fixed mast 52). Other variations in mounting the auxiliary display 232, such as the embodiment shown in FIG. 1A, are of course possible. Many alternative arrangements are also contemplated, which may be specific to the design, structure, function, and use of the peripheral.

[0056] 19 , a first cable 234 connects the display to the mast pump, while a second cable 236 connects the pump 170 to the power strip 220. For example, an additional cable 238 may be required to connect the display 232 to a main module connection station (not shown), which may be located, for example, in the base of the console 8 and accessible toward the operator side 28 of the console 8 by opening the front panel access door 38. As shown, the cables 234, 236 are routed from beneath the shelf 62, through one of the passages 208, 210 of the cable holder 200, and then into the raceway / channel 102 established by the cable chases 100, 136. In light of the versatile structure of the embodiments taught herein, improvements in use, setup time, and operation of the medical device system 10 can be achieved, particularly, but not limited to, improved use in the field of cardiopulmonary bypass.

[0057] Although the systems and methods have been described with reference to certain embodiments within the present disclosure, those skilled in the art will recognize that additions, deletions, substitutions, and modifications may be made while remaining within the scope and spirit of the invention. In addition, while the use of embodiments of the present disclosure may be beneficial in perfusion applications for living mammals and humans, the same may also be used with non-human subjects, including medical simulators, test or training mannequins, and the like.
