The disclosure generally relates to dialysis machines and systems, and more particularly to a mobile interface cart arranged and configured to pump effluent to a waste drain.
Dialysis machines are known for use in the treatment of renal disease. The two principal dialysis methods are hemodialysis (HD) and peritoneal dialysis (PD). During PD, a dialysis machine, such as a PD machine, may include one or more containers (e.g., bags) containing a fluid (e.g., dialysis solution) for patient infusion. In addition, a PD machine may include a removable and/or replaceable cartridge or cassette attached to one or more fluid lines for pumping fluid to and from a patient. During PD, for example, one or more fluid lines are inserted into an abdomen of a patient for flowing fresh dialysate and removing used dialysate, waste, and excess fluid (collectively referred to herein as spent dialysis and/or spent dialysate without the intent to limit). During a treatment operation, the PD machine pumps fluid, e.g., fresh and spent dialysate, to and from a patient. For example, the PD machine may pump dialysate from one or more dialysate bags and into the patient's abdomen. The dialysate may pass through a heating chamber to heat the dialysate to a predetermined temperature prior to inserting the dialysate into the machine. Next, the dialysis machine may remove the spent dialysate from the patient's abdomen. That is, after the dialysate has been inserted into the patient's abdomen and a prescribed amount of urea, creatine, water, and other waste matter (e.g., effluent) have been removed from the patient, the spent dialysate must be discarded.
During HD, a hemodialysis system is arranged and configured to, inter alia, pump a patient's blood through a dialyzer. In addition, the hemodialysis system includes a HD machine and one or more containers containing a fluid (e.g., a dialysate), which during use is also pumped through the dialyzer of the HD system simultaneously with the patient's blood. A semi-permeable membrane in the dialyzer separates the blood from the dialysate within the dialyzer and allows diffusion and osmosis exchanges to take place between the dialysate and the blood. Thus arranged, in use, the patient's blood is cleaned or filtered. That is, as will be readily appreciated by one of ordinary skill in the art, a hemodialysis system includes a HD machine including a dialysate flow path, an extracorporeal blood flow path, and a dialyzer. In addition, the hemodialysis system may include any number of additional components needed to manage, sense, etc. the flow of dialysate and/or blood through the system. In use, the HD machine and the dialysate flow path are arranged and configured to pump dialysate through the dialysate-side of the dialyzer. To this end, the HD machine may include, inter alia, first and second dialysate pumps to circulate dialysate through the dialysate path. In addition, the HD machine may include a sorbent cartridge for regenerating used or spent dialysate after it leaves the dialyzer. In use, the first and second pumps may move the dialysate through the sorbent cartridge and into a dialysate reservoir, out of dialysate reservoir, and back through the dialyzer.
The extracorporeal blood path includes a to-patient connector such as, for example, a needle, at the end of a venous return line, a from-patient connector such as, for example, a needle, at an end of an arterial line, and a blood pump arranged and configured to pump or pull blood from the patient through the arterial line through the blood side of the dialyzer and back to the patient through the venous return line.
In use, the dialyzer includes a cartridge comprising a semi-permeable membrane (e.g., a high flux membrane) arranged and configured to remove toxins from the blood. In one embodiment, the removal of toxins is accomplished by establishing a concentration gradient across the semi-permeable membrane by allowing the dialysate to flow on one side of the membrane in one direction while simultaneously allowing the blood to flow on the other side of the membrane in the opposite direction. The dialyzer may be of any type suitable for hemodialysis, hemodiafiltration, hemofiltration, or hemoconcentration, as are known in the art.
It should be appreciated that while a particular embodiment of a hemodialysis system including a dialysis flow path, an extracorporeal blood flow path, and a dialyzer have been described, any number of different hemodialysis systems now known or hereafter developed may be utilized. Further, the system described herein may be utilized in connection with other types of dialysis treatments, including, for example, hemofiltration, hemodiafiltration and/or PD systems.
Generally speaking, many dialysis treatments, especially HD, occur in outpatient treatment centers, rooms, facilities, or the like (terms used interchangeably herein without the intent to limit or distinguish). These treatment centers may be located within nursing homes, hospitals, Transitional Care Units (“TCUs”), stand-alone facilitates, etc. A common problem with these treatment centers is the initial construction cost and time for setting up the treatment centers. For example, these treatment centers require, inter alia, a dialysis den, which includes all of the necessary plumbing needed to discard effluent, fresh water used to flush and clean the HD system and/or to mix the dialysate, and any needed electrical power supply to perform the dialysis treatment. As a result, construction of dialysis dens is time-consuming and costly.
That is, in a HD treatment, effluent must be discarded into a waste drain. However, current systems only enable the drain tube to extend for short runs (e.g., 10 feet). As a result, the dialysis treatment needs to be performed in relatively close proximity to the waste drain. In addition, the drain tube relies on gravity to move (e.g., transport) the effluent and thus cannot rise vertically. As a result, generally speaking, each dialysis den includes modular chases (e.g., a designated area for receiving utilities), connection points for each patient's station, multiple waste drains for receiving the effluent, multiple water supply lines, etc. Each waste drain being constructed within the floor (e.g., concrete floor) of the dialysis den. Thus, dialysis dens often include multiple beds positioned adjacent to a waste drain constructed within a concrete floor.
It would be beneficial to provide a system that facilitates easier discarding of effluent. In addition, it would be beneficial to provide a device or system that reduces the initial construction time and cost associated with building dialysis dens. Moreover, it would be beneficial to provide a mobile system thus enabling the system to be easily removed if warranted. It is with respect to these and other considerations that the present improvements may be useful.

By way of example, specific embodiments of the disclosed methods and devices will now be described, with reference to the accompanying drawings, in which:
The present embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which several exemplary embodiments are shown. The subject matter of the present disclosure, however, may be embodied in many different forms and types of devices and systems for dialysis and other potential medical devices and treatments, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and willfully convey the scope of the subject matter to those skilled in the art. In the drawings, like numbers refer to like elements throughout.
Exemplary embodiments of a mobile interface cart used in connection with a dialysis system are disclosed herein. In use, the mobile interface cart is arranged and configured to be used with a dialysis machine, such as, for example, an HD machine or in an HD system. In accordance with one or more features of the present disclosure, the HD machine may be connected to the mobile interface cart via, for example, tubing, so that the used effluent from the HD machine may be transferred to a waste drain via the mobile interface cart. That is, in some embodiments, the mobile interface cart includes an effluent storage tank and a pump. In use, the effluent is transferred to the effluent storage tank. Thereafter, the pump may be activated to transfer or discard the effluent from the effluent storage tank to the waste drain located within the treatment center. Thus arranged, by utilizing a pump and a storage tank positioned within the mobile interface cart, increased flexibility and access to waste drains in the treatment center is provided, which reduces the initial construction cost and time associated with constructing waste drains in the concrete floor of the dialysis dens. In use, the mobile interface cart incorporating the pump enables the effluent to be transferred much greater distances and/or over and around obstacles (e.g., the pump enables the effluent to be transferred from the effluent storage tank to the waste drain over much longer runs thereby eliminating, or at least greatly minimizing, the need for the HD machine to be positioned adjacent or in close proximity to a waste drain).
In addition, in accordance with one or more features of the present disclosure, the mobile interface cart provides a self-contained device that facilitates easy repositioning of dialysis equipment. That is, for example, the mobile interface cart provides a self-contained device that enables treatment centers to easily reposition equipment as needed. In some embodiments, the mobile interface cart can be repositioned as needed. Once positioned, the mobile interface cart merely needs to be connected to (e.g., supplied with) electrical power, fresh water, and access to a waste drain.
While the mobile interface cart will be shown and described in the present disclosure for use with one or more dialysis machines, it should be appreciated that the mobile interface cart should not be limited to any particular type of dialysis machine. It is envisioned that the mobile interface cart according to one or more features of the present disclosure may be used in connection with other types of dialysis machines. Thus, the present disclosure should not be limited to any particular type of dialysis machine unless specifically claimed.
Referring to
In use, the mobile interface cart 100 is arranged and configured to receive the HD machine 50. For example, as illustrated, the mobile interface cart 100 includes a surface for positioning of the HD machine 50 thereon. In some embodiments, the top surface 102 of the front portion 140 may define the surface for receiving the HD machine 50 thereon. Thus arranged, the HD machine 50 may be positioned on the top surface 102 of the front portion 140 and be connected to the water box 200 and other components positioned within the intermediate, front facing surface 150, although this is but one configuration.
In addition, in some embodiments, the front portion 140 may include a cavity, a garage, an opening, or the like 160 (terms used interchangeably herein without the intent to limit or distinguish). In use, the cavity 160 is arranged and configured to receive and store, for example, the dialysate or dialysis solution (terms used interchangeably herein without the intent to limit or distinguish). For example, as illustrated in
The rear portion 120 of the mobile interface cart 100 may include an enclosure, a cabinet, or the like 180 (terms used interchangeably herein without the intent to limit or distinguish). As illustrated, the enclosure 180 may include a door 182 to facilitate opening and closing to selectively enable access to the interior space or cavity of the enclosure 180. With reference to
As previously mentioned, with reference to
In addition, the water box 200 includes one or more fresh water supply ports or connectors 204 for supplying water to, for example, the water and dialysate preparation device 75 and/or to supply fresh water for flushing and cleaning the HD system and tubes. For example, in some embodiments, as illustrated, the water box 200 includes a fresh water supply port 204 for supplying water to the water and dialysate preparation device 75 when used. In use, the fresh water supply port 204 is fluidly coupled to the water connection 194 for supplying fresh water. In use, the fresh water supply port 204 may be any suitable connector now known or hereafter developed such as, for example, a male quick disconnector.
In addition, the water box 200 includes one or more drain ports or connectors to connect to the various components to transfer the effluent and/or fresh water. For example, the water box 200 may include a drain coupling input port 205 to facilitate draining of the dialysis bags or containers with the output of the bags or containers diverting from input port 205 through output port 206 to drain, when the optional water and dialysate preparation device 75 is not used. In addition, the water box 200 may include a drain coupling input 209 for coupling from the optional water and dialysate preparation device 75 drain output, and when used, the output will be diverted through output port 207 to drain. In addition, the water box 200 may include a domestic water output port 208, which is utilized during flushing of the system when switch 203 is activated as will be described in greater detail below.
Thus arranged, the water box 200 includes one or more water connectors or connections and drain connectors or connections to connect to the various components including the HD machine 50 and the optional water and dialysate preparation device 75 or the dialysis bags or containers, etc. As such, the water box 200 connects the HD machine 50 and the water and dialysate preparation device 75 or dialysis bags or containers to the connection box 190 and to the storage tank 212 and pump 210 to transfer and drain fluid as needed. In use, the water box 200, and more specifically, the drain ports positioned within the water box 200, are in fluid connection with the storage tank 212, which is in fluid connection with the pump 210 via, for example, tubing. In addition, the pump 210 is in fluid connection via tubing with the drain connection 196. As such, in use, the HD machine 50 may be fluidly coupled to the drain ports in the water box 200. Thus arranged, the effluent from the HD process may be pumped by the HD machine 50 into the storage tank 212. Subsequently, the effluent may be pumped from the storage tank 212 to the external waste drain located within the treatment center via tubing connected to the drain connection 196.
In accordance with one or more features of the present disclosure, by incorporating the pump 210 into the mobile interface cart 100, increased flexibility to access the external waste drain in the treatment center is enabled. That is, in contrast to systems in which the HD machine is positioned adjacent to, or in close proximity with, the external waste drain formed in the floor of the treatment center, the mobile interface cart 100 enables the effluent to be pumped via tubing to the external waste drain located some distance from the HD machine. In addition, in contrast to systems which rely on gravity to move the effluent, the mobile interface cart 100 enables the effluent to be pumped via tubing up, over, around, etc. obstacles such as, for example, windows, doors, etc. That is, in use, by utilizing the mobile interface cart 100 with a pump 210, the effluent can be pumped via tubing to distant external waste drains positioned within the treatment centers thereby eliminating the need to install expensive waste drains in the floor of the treatment centers adjacent to the HD machines (e.g., the mobile interface cart 100 and the pump 210 enable the tubing to run longer distances and around obstacles providing significant benefits to the owner of the treatment centers). In some embodiments, it has been found that the effluent can be pumped vertically by a distance of ten (10) feet or more and effluent can be pumped horizontally by a distance of twenty (2), thirty (30), or more feet.
In some embodiments, the mobile interface cart 100 may also include a shutoff level to turn OFF the water supply, if needed, an alarm 201, for example, a visual alarm, to provide a visual indication that the pump 210 has failed as will be described in greater detail below, and a switch 203, such as, for example, a manual switch such as, a momentary push button switch, although other switches may be used, to flush the system and tubes, etc. (e.g., to run fresh water directly from the water connection 194 through the tubing). That is, in use, activation of the switch 203 initiates a wall box flush with fresh water (e.g., water received from the water connection 194 (e.g., a water inlet) is moved via the interconnecting tubing through the water box 200 to the storage tank 212 and pump 210 and out through the drain connection 196 (e.g., drain outlet) to the external waste drain in the treatment center. As such, the tubing and other connected components can be cleaned.
With reference to
In addition, with reference to
As previously mentioned, the mobile interface cart 100 includes a water connection 194 to supply fresh water to the mobile interface cart 100. In use, if utilized with the water and dialysate preparation device 75, the fresh water can be used to mix the dialysate. In addition, and/or alternatively, the fresh water can be used to flush (e.g., clean) the tubing. For example, in use, the mobile interface cart 100 may include the switch 203 positioned, for example, in the intermediate, front-facing surface 150. Activation of the switch 203 causes fresh water received through the water connection 194 to run through the tubing to flush and clean the tubing.
In use, the electrical box or control panel 214 is electrical coupled to the electrical connection 192 for receiving line-voltage power. In addition, the electrical box or control panel 214 is electrically coupled to any other components located in the mobile interface cart 100 to supply power as needed including, for example, the pump 210, the electrical outlet 202, the sensor system 218, etc. In addition, the electrical box or control panel 214 may include any necessary circuitry, processors, etc. needed to operate the components of the mobile interface cart 100.
Thus arranged, by incorporating one or more features of the mobile interface cart 100, the effluent from the HD dialysis procedure can be readily discarded without the need to construct expensive dens including multiple waste drains. Rather, in use, the mobile interface cart 100 can be positioned as needed in a treatment center. Thereafter, the mobile interface cart can be coupled to electrical and water supply lines. In addition, tubing can be coupled to the drainage access port, the tubing extending to an external waste drain positioned somewhere in the treatment center. As such, the need for expensive and time-consuming waste drains to be constructed within the floors adjacent to each HD machine is eliminated.
The mobile interface cart described herein has been explained in connection with dialysis machines and/or systems having a particular configuration. It is contemplated that the mobile interface cart described herein may be used with dialysis machines and/or systems having other configurations, for example, different types of dialysis machines. The s mobile interface cart described herein may be used with any appropriate dialysis machine and/or system.
