Description

Technical Field

[0001] The present disclosure relates to systems and related methods for supporting medical fluid bags. Background Art

[0002] Dialysis is a treatment for patients who are supporting renal insufficiency. Two main dialysis methods are hemodialysis and peritoneal dialysis. During hemodialysis ("HD"), the patient's blood passes through the dialyzer of a dialysis machine while also passing a dialysis solution or dialysate through the dialyzer. A semipermeable membrane in the dialyzer separates the blood in the dialyzer from the dialysate and allows diffusion and osmotic exchange to occur between the dialysate and the bloodstream. These transmembrane exchanges remove waste from the blood, including solutes such as urea and creatinine. These exchanges also regulate the levels of other substances such as sodium and water in the blood. In this way, the dialysis machine acts as an artificial kidney for purifying blood.

[0003] During peritoneal dialysis ("PD"), the patient's peritoneal cavity is regularly infused with a dialysate solution. The membranous lining of the patient's peritoneum acts as a natural semipermeable membrane that allows diffusion and osmotic exchanges between the solution and the bloodstream. These exchanges across the patient's peritoneum allow waste products, including solutes like urea and creatinine, to be removed from the blood, and regulate the levels of other substances in the blood, such as sodium and water.

[0004] Continuous Ambulatory Peritoneal Dialysis (CAPD) therapy involves hanging a bag of fresh dialysate and using gravity to fill the patient's peritoneal cavity. At the end of the dwell phase of the treatment cycle, the effluent (spent dialysate) is drained from the patient's peritoneal cavity into a drainage system via gravity. Summary of the invention

[0056] In some embodiments, the basin system is designed to be portable. For example, the basin system can include one or more wheels so that the system is easily moved between treatments.

[0057] In addition, the basin system can provide safe and effective heating of medical fluid contained in a medical fluid bag. For example, the basin system can include a heating system configured to heat medical fluid contained in a medical fluid bag placed on a tray of the basin system.

[0077] Figure 1 A patient 110 is shown receiving peritoneal dialysis ("PD") treatment using a PD system 100. The PD system 100 includes a dialysate bag 102 suspended from a stand 104. A fluid line 106 connects the dialysate bag 102 to a transfer set 108 connected to the patient 110. A drain bag 112 is fluidly connected to the transfer set 108 via a fluid line 114. The PD system 100 includes a basin system 116 on which the drain bag 112 is positioned during treatment.

[0078] Figure 1 The PD system 100 can be used to perform continuous ambulatory peritoneal dialysis (CAPD) treatment. CAPD treatment usually starts by draining fluid from the patient's peritoneal cavity. Once the patient's peritoneum has been emptied, the patient's peritoneal cavity is filled with fluid (e.g., dialysate), which then stays in the patient's peritoneal cavity. After the dialysate is delivered to the patient's peritoneal cavity and allowed to stay in the peritoneal cavity for a predetermined period of time, the dialysate is drained from the peritoneal cavity. These processes of draining, filling, staying, and draining are repeated throughout the CAPD treatment cycle.

[0079] To drain fluid from the patient's peritoneal cavity, the PD system 100 includes a drain bag 112 that is fluidly connected to the patient's peritoneal catheter using a transfer device 108. During the drain phase of PD therapy, the drain bag 112 is coupled to the patient's transfer device 108 using a fluid line 114, and fluid flows from the peritoneal cavity of the patient 110 along the fluid line 114 into the drain bag 112. During the drain phase of PD therapy, the drain bag 112 is positioned on and supported by the basin system 116.

[0080] Once the fluid in the patient's peritoneal cavity has been drained, the fill phase of the PD treatment can be performed by connecting a dialysate bag 102 filled with dialysate to the patient's peritoneal catheter using a transfer device 108 and delivering approximately 1-3 liters of dialysate to the peritoneal cavity. As will be described in further detail herein, in some embodiments, the dialysate in the dialysate bag 102 is heated prior to initiating the fill phase.

[0081] In order to fill the patient's peritoneal cavity with dialysate without the use of a pump, the dialysate bag 102 is positioned above the transfer device 108, which allows the patient's peritoneal cavity to be filled by gravity. By suspending the dialysate bag 102 on the support 104, the dialysate flows down the fluid line 106 via gravity and into the transfer device 108. A clamp 118 is provided along the fluid line 106 to control the flow of fluid from the dialysate bag 102 along the fluid line 106. For example, once the dialysate bag 102 has been attached to the support 104 and opposite ends of the fluid line 106 are coupled to the dialysate bag 102 and the transfer device 108 coupled to the patient's peritoneal catheter, the clamp 118 along the fluid line 106 can be opened to allow the dialysate to flow from the dialysate bag 102 along the fluid line 106 via gravity, through the transfer device 108 and the patient's catheter, and into the peritoneal cavity of the patient 110.

[0082] As will be described in further detail herein, the basin system 116 can help the user perform PD treatment. For example, during PD treatment, the patient 110 or another user typically monitors and records various data about the treatment, such as dialysate concentration, dialysate expiration date, dialysate volume exchanged during treatment, fill start time, fill end time, residence time, discharge start time, discharge end time, the amount of fluid discharged during treatment, and the clarity of the effluent discharged during treatment. As will be described in detail herein, the basin system 116 can be used to help the patient 110 monitor and record such data about PD treatment. The basin system 116 can also be used to heat the dialysis fluid contained in the dialysate bag 102 before the dialysate in the dialysate bag 102 flows to the peritoneum of the patient 110, as will be described below.

[0083] Figure 2 An example basin system 116 is shown for use during PD treatment. Figure 2 As shown, the basin system 116 includes a tray 202 and a basin 204. The tray 202 is positioned on top of the basin 204 to support and position a fluid bag such as the dialysate bag 102 or the drain bag 112 above the basin 204 during PD treatment. For example, during the drain phase of PD treatment, the drain bag 112 is positioned on the tray 202 above the basin 204, such as Figure 3During the dialysate warming step prior to the filling phase of PD treatment, the dialysate bag 102 is positioned on a tray 202 above a basin 204 .

[0084] like Figure 2 and Figure 4 As shown, the basin 204 includes a weight scale 206, and during PD treatment, the tray 202 is positioned on and in contact with the weight scale 206. As will be described in further detail herein, the weight scale 206 can be used to measure the weight or weight change of the dialysate bag 102 and / or the drain bag 112 positioned on the tray 202 in order to determine various data of the treatment cycle. This data may include, for example, the drain start time, the drain end time, the length of time elapsed during the drain phase, the amount of fluid drained from the patient, and the volume of fluid contained in the dialysate bag that was heated prior to the fill phase of treatment using the basin system 116.

[0085] Figure 5 and Figure 6 A tray 202 is shown that can be used to support the dialysate bag 102 and / or drain bag 112 over a basin 204 during treatment. Figure 5 and Figure 6 As can be seen in the figure, the tray 202 defines a plurality of openings 210 therethrough, which allow fluid to flow through the tray 202 into the basin 204 when the tray 202 is positioned over the basin 204. For example, if the drain bag 112 or dialysate bag 102 positioned on the tray 202 has a leak, the fluid leaking from the bag can flow into the basin 204 through the openings 210 in the tray 202 and be collected in the basin 204.

[0086] like Figure 5 As shown, the tray 202 is curved along its length toward a central channel 212 that passes through the tray 202. Due to the curved shape of the tray 202, fluid on the surface of the tray 202, such as fluid leaking from a fluid bag positioned on the tray 202, is directed by gravity to the central channel 212 in the tray 202 and drains through the central channel 212 into the basin 204. For example, the curved shape of the tray 202 causes fluid on the top surface of the tray between the openings 210 to be directed to the central channel 212 and into the basin 204. As will be described in further detail herein, in some embodiments, the basin 204 includes a leak detection sensor, and channeling fluid that has leaked onto the tray 202 and is directed into the basin 204 through the openings 210 and the central channel 212 allows leaks in a fluid bag (e.g., the drain bag 112) placed on the tray 202 to be detected by the system 116.

[0087] refer to Figure 5 and Figure 6, the tray 202 defines handles 214, 216. The handles 214, 216 can be used to carry the tray 202 and easily lift the tray 202 from the basin 204, for example, during cleaning of the tray 202 and the basin 204.

[0088] The tray 202 also includes conductive wick elements 218, 220. The conductive wick elements 218, 220 extend through the tray 202 and are positioned on the tray 202 to contact a fluid bag (e.g., dialysate bag 102 or drain bag 112) positioned on the tray 202. The conductive wick elements 218, 220 can interact with one or more heating elements in the basin 204 to heat the fluid contained in the fluid bag positioned on the tray 202. For example, before performing a fill, the dialysate bag 102 can be placed on the tray 202, and heating the conductive wick elements 218, 220 by the heating elements in the basin 204 can heat the dialysate contained in the bag, thereby warming the dialysis fluid for PD treatment.

[0089] from Figure 6 and Figure 7 As can be seen in FIG. 2 , the tray 202 includes contrasting text 222 that allows a user of the basin system 116 to check the clarity of the fluid contained within the fluid bag positioned on the tray 202. For example, referring to Figure 1 and Figure 7 During PD treatment, drain bag 112 may be placed on tray 202, and contrast text 222 may be used by patient 110 (or another user of system 100) to visually check the clarity of effluent draining from patient 110 into drain bag 112. For example, patient 110 or another user of system 100 may check the clarity of effluent draining from patient 110 into drain bag 112 by determining whether the drained effluent is clear enough that contrast text 222 on tray 202 is visible through the effluent in drain bag 112. If contrast text 222 on tray 202 is not visible through the effluent in drain bag 112 due to turbidity or discoloration of the effluent, this indicates that patient 110 may be experiencing an infection, such as peritonitis. By using the contrasting text 222 on the tray 202 to check the clarity of the effluent discharged from the patient 110, the patient 110 or another user of the system 100 is quickly and easily alerted to the potential infection that the patient 110 may be experiencing, and can seek appropriate medical care for the patient 110. The contrasting text 222 is printed on the surface of the tray 202 in a color that contrasts with the color of the tray 202.

[0090] Figure 8 Shows Figure 1The basin 204 of the basin system 116 is configured to cooperate with the tray 202 of the system 116 to support a fluid bag (e.g., a dialysate bag 102 or a drain bag 112) placed on the tray 202 during PD treatment and to collect any fluid leaking from the fluid bag placed on the tray 202. The control unit 242 (e.g., a microprocessor) of the basin 204 can be used to record, store, and wirelessly transmit one or more parameters related to the PD treatment.

[0091] Still reference Figure 8 , the basin 204 includes a housing 230 defining a chamber 236. The chamber 236 is configured to collect fluid that leaks onto the tray 202 and into the basin 204. Figure 3 As shown in FIG. 2 , the tray 202 of the basin system 116 is positioned above the chamber 236 , and the dialysate bag 102 or the drain bag 112 (depending on the stage of PD treatment) is placed on top of the tray 202 .

[0092] For example, during a dialysate heating step prior to the filling phase, the dialysate bag 102 is positioned on the tray 202 and the dialysate in the dialysate bag 102 is heated prior to delivery to the patient. If the dialysate bag 102 develops a leak while the tray 202 is positioned for heating, the dialysate will flow out of the dialysate bag 102, through the opening 210 and central channel 212 of the tray 202, and into the chamber 236 of the basin 204. Once the dialysate in the dialysate bag 102 has been heated and no leaks from the bag 102 are detected, the dialysate bag 102 is removed from the tray 202 and attached to the rack 104 so that the dialysate can be provided to the patient via gravity during treatment.

[0093] During the drain phase of PD therapy, the drain bag 112 is positioned on the tray 202, and effluent drains from the patient 110 and flows into the drain bag 112. If the drain bag 112 develops a leak, the effluent will flow out of the drain bag 112, through the opening 210 and central channel 212 of the tray 202, and into the chamber 236 of the basin 204.

[0094] refer to Figure 8 and Fig. 9, the housing 230 of the basin 204 further defines a drain opening 244 extending through the housing 230. An expandable plug 232 may be inserted into the drain opening 244 to seal the drain opening 244 and prevent fluid from flowing out of the chamber 236 through the drain opening 244. For example, during PD treatment, the expandable plug 232 may be disposed in the drain opening 244 to prevent any fluid leaking from a fluid bag positioned on the tray 202 from flowing out of the chamber 236 of the basin 204. The expandable plug 232 may be removed to drain the fluid from the chamber 236 of the basin 204, for example, to clean the basin 204. The fluid collected in the chamber 236 is drained by positioning the basin 204 over a toilet, bathtub, or sink and removing the expandable plug 232 from the drain opening 244 to allow the fluid in the chamber 236 to flow through the drain opening 244 into the toilet, bathtub, or sink.

[0095] like Fig.10 , the bottom surface 246 of the chamber 236 is inclined inwardly toward the drain opening 244 in the chamber 236 to direct fluid leaking into the chamber 236 to the drain opening 244. The curved bottom surface 246 of the chamber 236 allows for improved ease of draining the fluid out of the chamber 236 by directing the fluid in the chamber 236 toward the drain opening 244. In some embodiments, the bottom surface 246 of the chamber 236 is transparent to allow a user to more easily inspect the color and clarity of the effluent contained in the drain bag 112 positioned above the basin 204 (e.g., via the tray 202 coupled to the basin 204).

[0096] The basin 204 also includes a leak detector 234 for detecting fluid that has leaked into the basin 204. The leak detector 234 is positioned within the chamber 236 and includes a moisture sensor configured to detect when fluid contacts the leak detector 234. For example, if a fluid bag (e.g., a dialysate bag 102 or a drain bag 112) positioned on the tray 202 leaks fluid (e.g., dialysate or effluent) onto the tray 202, into the chamber 236 of the basin 204, and contacts the leak detector 234 in the chamber 236, the leaked fluid will be automatically detected by the leak detector 234.

[0097] Leak detector 234 is formed of a conductive (eg, metal) material configured to detect when a fluid, such as leaking dialysate or effluent, contacts leak detector 234. Figure 8 and Fig.10116, wherein the leak detector 234 is formed as two concentric metal rings 213, 233 that are positioned within a channel formed between the scale 206 and the bottom surface 246 of the chamber 236, wherein the first ring 231 serves as a positive terminal and the second ring 233 serves as a negative terminal. In addition, the bottom surface 246 of the chamber 236 is sloped to direct fluid that leaks into the chamber 236 via gravity toward the leak detector 234. Positioning the leak detector 234 within the chamber 236 such that the sloped bottom surface 246 of the chamber 236 directs fluid that leaks from the fluid bag to the leak detector 234 allows for rapid detection of any leaks in the fluid bag supported by the system 116.

[0098] When a conductive fluid, such as dialysate or effluent, leaks into the chamber 236 and contacts the two metal rings 231, 233 of the leak detector 234, the leaked fluid bridges the gap between the metal rings 231, 233 and allows current to flow from the positive terminal to the negative terminal to complete the circuit. In response to the completion of the circuit formed by the leak detector, the leak detector 234 can generate a signal indicating that moisture has been detected in the basin 204 and transmit the signal to the computing device. For example, the leak detector 234 can be configured to transmit a signal to the control unit 242 of the basin 204 in response to the fluid contacting the leak detector 234. In response to receiving a signal indicating a leak from the leak detector 234, the control unit 242 can generate an alarm indicating that a leak in the fluid bag on the tray 202 has been detected by the system 116. In response to the control unit 242 receiving a signal indicating the presence of a fluid leak from the leak detector 234, the control unit 242 can control the graphical display 238 on the basin 204 to display a message or warning indicating that the system 116 has detected a fluid leak from the fluid bag. Alternatively or additionally, control unit 242 may control speaker 240 of basin 204 to sound an audible alarm indicating that system 116 has detected a fluid leak.

[0099] Return to reference Figure 2 and Figure 8 , the basin 204 also includes a weight scale 206 configured to measure the weight of the fluid contained in the fluid bag (e.g., dialysate bag 102 or drain bag 112) positioned on the tray 202 of the basin system 116. The weight scale 206 may include a load cell configured to measure the force applied to the weight scale 206 by the tray 202 positioned on the weight scale 206 together with any object positioned on the tray 202, such as the drain bag 112 or the dialysate bag 102.

[0100] The weight scale 206 is communicatively coupled to the control unit 242 of the basin 204 and is configured to transmit a signal indicative of a weight detected by the weight scale 206 to the control unit 242. For example, to determine the amount of fluid drained from the patient 110 during the drain phase of a PD therapy cycle, an empty drain bag 112 may be placed on the tray 202, and the weight scale 206 may detect an increment of weight applied to the weight scale 206 corresponding to a predetermined initial weight indicating that an empty drain bag 112 has been placed on the tray 202. The weight corresponding to the empty drain bag 112 may be recorded and stored by the control unit 242 of the basin 204. In response to the scale 206 detecting a weight indicating that an empty drain bag 112 has been placed on the tray 202, the weight scale 206 may send a signal to the control unit 242 indicating the start time of the drain phase of the cycle, and may begin measuring the weight of the tray and drain bag 112 as the drain phase progresses.

[0101] Once the drain phase has ended, and therefore no additional fluid has been added to the drain bag 112 for a predetermined amount of time, the weight scale 206 can detect that a predetermined amount of time has passed since the scale 206 detected any weight increase, and in response, can send a signal to the control unit 242 indicating the end time of the drain phase of the treatment cycle.

[0102] Control unit 242 may determine the duration of the discharge phase of the PD therapy cycle based on the signal received from weight scale 206. For example, control unit 242 may calculate the amount of time that elapses between the time when weight scale 206 sends a signal indicating an initial weight of the discharge phase and the time when weight scale 206 sends a signal indicating a final weight of the discharge phase to determine the duration of the discharge phase.

[0103] Control unit 242 may also use the signal received from weight scale 206 to determine the total amount of fluid drained from patient 110 during a PD therapy cycle. For example, control unit 242 may calculate the difference between the final weight measured by weight scale 206 during the drain phase of the therapy cycle and the initial weight measured by weight scale 206 at the beginning of the drain phase of therapy to determine the total weight of effluent drained from patient 110 and captured in drain bag 112 during the drain phase of the cycle.

[0104] In addition, the weight scale 206 can be used to determine the volume of dialysate contained in the dialysate bag 102 used during the filling phase of the PD treatment cycle. For example, before the filling phase of the treatment begins, the dialysate bag 102 can be positioned on the tray 202 to heat the dialysate in the bag 102, as will be described in further detail herein. When the dialysate bag 102 is heated by the system 116, the weight of the dialysate bag 102 positioned on the tray 202 can be automatically detected by the weight scale 206, and a signal can be transmitted from the weight scale 206 to the control unit 242 of the basin 204, indicating the initial weight of the dialysate bag 102. Based on the weight detected by the scale 206, the volume of the dialysis fluid in the dialysate bag 102 can be determined by the control unit 242. Once the dialysate in the dialysate bag 102 has been heated, the dialysate bag 102 is removed from the tray 202 and attached to the bracket 104 so that the dialysate can be provided to the patient via gravity during treatment.

[0105] In some embodiments, the system 116 automatically powers on or wakes from sleep mode in response to the weight scale 206 detecting an increase in weight corresponding to either a full dialysate bag or an empty drain bag placed on the tray 202 .

[0106] like Figure 8 and Fig.13 As shown in , the basin 204 includes an effluent sensor 248 configured to detect one or more characteristics of effluent contained in the drain bag 112 on the tray 202 positioned above the effluent sensor 248. In some embodiments, the effluent sensor 248 is an optical sensor configured to transmit and detect light in the visible spectrum and / or UV spectrum. For example, the effluent sensor 248 can be an optical sensor configured to detect various colors of effluent in the drain bag 112 corresponding to various conditions, including but not limited to hemoperitoneum, chylous effluent, bile in the effluent, duodenal ulcer perforation, large intestine perforation, dye in the effluent (e.g., produced by fluorescein angiography), reaction of icodextrin with iodine, methaqualone pancreatitis, and intravenous administration of dextran and rifampicin. The effluent sensor 248 can also be used to determine the clarity of the effluent discharged from the patient 110.

[0107] refer to Fig.13 During or at the end of the drain phase of a PD therapy cycle, effluent sensor 248 may be operated to determine the color and clarity of effluent contained in drain bag 112 positioned on tray 202 of system 116. In some cases, effluent sensor 248 is controlled to scan effluent in response to a user command to activate effluent sensor 248 received via graphic display 238 or microphone 241 of basin 204.

[0108] The effluent sensor 248 is communicatively coupled to the control unit 242 of the basin 204 and is configured to transmit signals indicative of one or more characteristics of effluent discharged from the patient to the control unit 242. For example, in response to the effluent sensor 248 scanning the effluent in the effluent bag 112 positioned on the tray 202, the effluent sensor 248 can transmit signals indicative of one or more characteristics of the effluent, such as clarity and color, to the control unit 242 of the basin 204 (e.g., wired or wirelessly). In some embodiments, the control unit 242 records the effluent characteristics received from the effluent sensor 248 in a local data storage device. In some embodiments, the control unit 242 transmits the effluent characteristics received from the effluent sensor 248 to one or more remote computing devices, such as remote data storage devices.

[0109] In some embodiments, when the effluent sensor 248 has completed scanning the drain bag 112, the control unit 242 controls the graphical display 238 to display a message indicating the results of the effluent scan. In some embodiments, when the effluent sensor 248 has completed scanning the drain bag 112, the control unit 242 controls the speaker to emit an audible message indicating the results of the effluent scan. By automatically monitoring effluent conditions using the effluent sensor 248 and notifying the patient or another user of the results of the effluent scan, patient safety can be improved through early detection of signs of infection.

[0110] from Figure 8 As can be seen in the figure, the basin 204 also includes one or more heating elements 250, 252. The heating elements 250, 252 can be used to heat the fluid contained in the fluid bag positioned on the tray 202 of the system 116. For example, before performing the filling phase of a PD treatment cycle, the fresh dialysis fluid in the dialysate bag 102 is heated to a predetermined temperature. To accomplish this pre-treatment heating, the dialysate bag 102 can be placed on the tray 202 of the system 116, and the heating elements 250, 252 in the basin can transfer heat to the dialysate bag 102, thereby heating the dialysis fluid contained in the dialysate bag 102.

[0111] The heating elements 250, 252 can be controlled by the control unit 242 to provide heat at a specific temperature. For example, the control unit 242 can control the heating elements 250, 252 to heat to a predetermined temperature within a predetermined amount of time. In some embodiments, the user can input a temperature (e.g., using the graphical display 238 or microphone 241 of the basin 204), and the control unit 242 controls the heating elements 250, 252 to heat to the user-specified temperature.

[0112] Once a predetermined or user-specified temperature is reached, the basin system 116 can alert the user. For example, in some embodiments, the system 116 includes a temperature sensor (e.g., one or more thermistors) in contact with the dialysate bag 102, such as a temperature sensor positioned on the tray 202, which detects the temperature of the fluid in the dialysate bag 102 and transmits a signal indicating the temperature of the dialysate to the control unit 242. In response to receiving a signal from the one or more temperature sensors indicating that the fluid in the dialysate bag 102 has reached a predetermined or user-specified temperature, the control unit 242 of the basin 204 can cause a visual alarm to be displayed on the graphical display 238 or cause the speaker 240 to emit an audible alarm indicating that the dialysate in the bag 102 has been heated to the predetermined or user-specified temperature.

[0113] The heating elements 250 , 252 are configured to contact and heat the conductive wick elements 218 , 220 extending through the tray 202 , which in turn heat the fluid contained within the fluid bags positioned on the tray 202 . Fig.11 and Fig.12 A schematic cross-sectional view of the basin system 116 is shown, illustrating the interaction of the heating elements 250, 252 in the basin 204 with the conductive core elements 218, 220 of the tray 202. Fig.11 and Fig.12 204, the conductive wick elements 218, 220 are aligned with and positioned over the heating elements 250, 252 of the basin 204. When the heating elements 250, 252 are activated, the contact between the conductive wick elements 218, 220 and the heating elements 250, 252 causes the temperature of the conductive wick elements 218, 220 to increase, which heats the fluid contained in any fluid bag positioned on the tray 202.

[0114] The basin includes depressible members 254, 256 to control contact between the conductive core elements 218, 220 and the heating elements 250, 252. The depressible members 254, 256 may include, but are not limited to, coil springs, leaf springs, wave springs, or torsion springs. The depressible members 254, 256 are positioned within the cavity 236 of the basin 204 and contact the tray 202 when the tray 202 is positioned over the basin 204 and coupled to the basin 204. Fig.11 As can be seen in FIG. 2 , when the tray 202 is empty or supports a small amount of weight, such as an empty fluid bag, the depressible members 254, 256 remain in an expanded configuration, which prevents the conductive core elements 218, 220 from contacting the heating elements 250, 252 in the basin 204. When a threshold amount of force is applied to the tray 202, the depressible members 254, 256 are compressed (e.g., Fig.12), which causes the conductive core elements 218, 220 to contact the heating elements 250, 252 in the basin 204. Whenever the heating elements 250, 252 are activated, as shown Fig.12 As shown, the contact between the conductive core elements 218, 220 and the heating elements 250, 252 heats the conductive core elements 218, 220. In some embodiments, the threshold amount of force required to compress the depressible members 254, 256 corresponds to a full or nearly full fluid bag (e.g., Fig.12 The force applied by the dialysate bag 102 in the dialysis chamber.

[0115] Once the threshold amount of force applied to the tray 202 is removed, the depressible members 254, 256 return to their expanded states, such that the conductive core elements 218, 220 no longer contact the heating elements 250, 252. For example, by removing the dialysate bag 102 from the tray 202, the depressible members 254, 256 return to their expanded states and separate the conductive core elements 218, 220 from the heating elements 250, 252, as shown in FIG. Fig.11 By preventing the conductive core elements 218 , 220 in the tray 202 from contacting the heating elements 250 , 252 when the tray 202 is empty, the fluid bag can be safely heated while reducing the risk of injury (eg, burns) to a user of the system 116 .

[0116] For example, when a fresh dialysate bag 102 is placed on the tray 202, the depressible members 254, 256 are compressed and the conductive wick elements 218, 220 contact the heating elements 250, 252, causing the heating elements 250, 252 to heat the conductive wick elements 218, 220 when the heating elements 250, 252 are activated. As the heating elements 250, 252 heat the conductive wick elements 218, 220, heat is transferred from the conductive wick elements 218, 220 to the dialysate in the dialysate bag 102, thereby heating the dialysate. Once the dialysate bag 102 has been heated to the desired temperature for treatment, the dialysate bag 102 is removed from the tray 202, which causes the depressible members 254, 256 to return to their expanded states (e.g., Fig.11 ), and as a result, the conductive core elements 218 , 220 are lifted out of contact with the heating elements 250 , 252 .

[0117] Furthermore, in some embodiments, the heating elements 250, 252 are automatically deactivated when a force exceeding a threshold force is no longer applied to the tray 202. For example, when the dialysate bag 102 has been heated and removed from the tray 202, such as Fig.11As shown, the weight scale 206 detects the weight decrease caused by the removal of the dialysate bag 102 and transmits a signal indicating the updated, decreased weight to the control unit 242. In response to receiving the signal indicating the weight decrease from the weight scale 206, the control unit 242 deactivates the heating elements 250, 252. By deactivating the heating elements 250, 252 in response to the removal of the fluid bag from the tray 202, the fluid bag can be heated safely while reducing the risk of injury (e.g., burns) to a user of the system 116.

[0118] The heating elements 250, 252 in the basin 204 may be inductive heating elements including inductive coils. For example, when the conductive core elements 218, 220 are in contact with the heating elements 250, 252, the inductive coils of the heating elements 250, 252 may generate a magnetic field that is transferred to the conductive core elements 218, 220, which in turn heats the conductive core elements 218, 220. By using the inductive heating elements 250, 252, the conductive core elements 218, 220 are heated above room temperature only when in contact with the heating elements 250, 252, and the rest of the system 116, including the heating elements 250, 252, remains at room temperature during the heating process. Thus, the fluid bag may be heated quickly and safely while reducing the risk of injury (e.g., burns) to a user of the system 116.

[0119] The basin 204 also includes one or more light emitting diodes (LEDs) 258 to indicate when the fluid bag is being heated by the system 116. For example, when a fluid bag (e.g., dialysate bag 102) is positioned in the tray 202 (as determined based on a signal transmitted by the weight scale 206) and the heating elements 250, 252 are activated, the one or more LEDs 258 on the basin 204 are illuminated to indicate that the fluid bag is being heated by the basin 204. Once the fluid bag is removed from the tray 202, as determined based on a decrease in weight measured by the weight scale 206, or once the heating elements 250, 252 are deactivated, the LEDs 258 are turned off.

[0120] Return to reference Fig. 9 , the basin 204 includes wheels 260, 262, 264, 266 that allow easy movement of the system 116. Each wheel is coupled to a bottom surface 268 of the basin 204 near a corresponding corner of the basin 204. The wheels 260, 262, 264, 266 can be full-swivel wheels. In some cases, one or more of the wheels 260, 262, 264, 266 include locking casters that can be engaged to lock the corresponding wheel 260, 262, 264, 266 and temporarily prevent movement of the basin 204 (e.g., during treatment).

[0121] refer to Fig.14, basin 204 includes a power adapter 270, which can be used to connect basin 204 to a power source to provide power to one or more components of basin 204. Basin 204 may include a rechargeable battery for powering various components of basin 204, such as weight scale 206, effluent sensor 248, and control unit 242. The battery can be charged by connecting power adapter 270 to a power source (e.g., using a cable). In some embodiments, power adapter 270 is a 60-watt power adapter. Basin 204 also includes a switch 272 for turning the electronic components of basin 204 on and off.

[0122] from Figure 8 As can be seen in the figure, the basin 204 also includes ports 274, 276 that are configured to be coupled to an electronic device. For example, the ports 274, 276 can be configured to be able to interface with a portable memory device, such as a universal serial bus (USB) storage device or other flash memory card, to store one or more treatment parameters captured by the system 116 on the storage device. For example, the control unit 242 can transmit one or more treatment parameters received and recorded by the control unit 242 to a portable memory device coupled to one of the ports 274, 276 on the basin 204. In some embodiments, the control unit 242 is configured to be able to generate a treatment report containing all treatment parameters of the most recent PD treatment performed using the system, and export the treatment report to a portable memory device coupled to one of the ports 274, 276 on the basin 204.

[0123] refer to Figure 1 , the PD system 100 includes a flow sensor 120 configured to measure the fluid flowing from the dialysate bag 102 into the peritoneal cavity of the patient during the filling phase of the treatment cycle. The flow sensor 120 can be coupled to the fluid line 106 between the dialysate bag 102 and the transfer device 108 to measure the fluid flow along the fluid line 106. The flow sensor 120 detects and records the time when the flow through the fluid line 106 is first sensed (corresponding to the start time of the filling phase) and the time when the flow along the fluid line 106 stops (corresponding to the end time of the filling phase). During the filling phase, the flow sensor 120 measures the amount of dialysis fluid provided to the patient 110 via the fluid line 106 during the filling phase.

[0124] At the end of the fill phase of the PD therapy, the user can connect the flow sensor 120 to the ports 274, 276 on the basin 204, and the flow data captured by the flow sensor 120 can be transmitted to the control unit 242 of the basin 204. Based on the data provided by the flow sensor 120, the control unit 242 can determine various parameters for the fill phase of the therapy, including the fill start time, the fill end time, the amount of time that elapsed during the fill phase, and the amount (e.g., volume) of fill fluid provided to the patient 110 during the fill phase. In some embodiments, the control unit 242 transmits therapy data determined based on the data received from the flow sensor 120 to one or more remote computing devices.

[0125] In some embodiments, control unit 242 can compare data regarding fill volume received from flow sensor 120 during the fill phase with data indicating the amount drained from the patient during the drain phase (e.g., based on data received from weight scale 206) to determine the ultrafiltration efficacy of the treatment cycle. For example, the difference between the fill volume measured by the flow sensor and the amount of fluid drained from the substrate determined based on data received from weight scale 206 indicates the additional amount of fluid drained from the patient during the drain phase, which can be used to analyze the ultrafiltration efficiency of the treatment.

[0126] In some embodiments, the control unit 242 determines an end time of the fill phase of the cycle based on the received flow sensor 120 data, and based on the fill phase end time, the basin 204 generates an alarm indicating to the user that the dwell period is complete after a predetermined amount of time has passed from the fill end time. For example, after a predetermined amount of time corresponding to the dwell time has passed from the fill phase end time, the control unit 242 can control the graphical display 238 to display an alarm indicating that the dwell phase is complete and the drain phase can begin. In some embodiments, after a predetermined amount of time corresponding to the dwell time has passed from the fill phase end time, the control unit 242 can control the speaker 240 to emit an audible alarm indicating that the dwell phase is complete and the drain phase can begin.

[0127] The control unit 242 may utilize data received from the flow sensor 120 and the weight scale 206 to determine the dwell time performed during the treatment cycle. For example, the end time of the fill cycle may be determined based on data indicating the time at which the flow sensor 120 ceased to detect flow along the fluid line 106 between the dialysate bag 102 and the transfer device 108. Similarly, the start time of the drain cycle may be determined based on a first weight increase above a threshold amount recorded by the weight scale 206 after the end of the fill phase. The control unit 242 may then determine the total dwell time based on the time elapsed between the end time of the fill phase and the start time of the drain phase as determined by the data received from the flow sensor 120 and the weight scale 206.

[0128] As previously described, the graphics display 238 ( Figure 8 ) can be configured to display messages, such as alarms and warning messages, to a user of the basin system 116. In some embodiments, the control unit 242 controls the graphical display 238 to display messages and alarms in response to the control unit 242 receiving a signal from one or more sensing elements of the basin 204, such as the leak detector 234, the weight scale 206, or the effluent sensor 248.

[0129] Graphical display 238 may be a touch screen display and may be used to display a graphical user interface. A user may interact with the graphical user interface displayed on graphical display 238 to control the operation of one or more components of basin 204, such as controlling weight scale 206 to perform weight measurements or controlling effluent sensor 248 to analyze effluent contained in drain bag 112 positioned on tray 202.

[0130] In addition, the user may use the graphical user interface displayed on the graphical display 238 to input data regarding the PD treatment, such as the clarity of the effluent drained from the patient during the drain phase, the concentration of the dialysis fluid used for the fill phase, the start time of the fill phase, the end time of the fill phase, the expiration date of the dialysate used for the fill phase, the volume of dialysate to be provided to the patient during the fill phase, the clarity of the dialysate used for the fill phase. The treatment data input by the user using the graphical display 238 is received by the control unit 242 of the basin 204, and the control unit 242 may transmit the treatment data to one or more remote computing devices for storage and evaluation.

[0131] The graphical user interface displayed on the graphical display 238 can also be used to access treatment history. For example, a patient's previous treatment history can be displayed on the graphical display 238 of the basin 204. In some embodiments, in response to a user request for treatment history (e.g., input by the user using the graphical display 238), the control unit 242 wirelessly communicates with one or more remote storage devices to retrieve the patient's treatment history and controls the graphical display 238 to visually display the retrieved treatment history data. In some embodiments, the patient's treatment history is encrypted, and the user must provide credentials in order to access the encrypted treatment data. For example, the user can provide credentials via a GUI displayed on the graphical display 238 or via voice control using the microphone 241. The credentials required to retrieve the encrypted treatment data may include a patient identification number, a password, a fingerprint, or retinal scan data.

[0132] The speaker 240 and microphone 241 of the basin can be used together to collect treatment data from a user of the system 116. For example, the speaker 240 can be controlled to audibly issue one or more questions regarding various treatment data, and the microphone 241 can be used to capture the user's response to each question issued by the speaker 240. In some embodiments, the speaker 240 is controlled to issue one or more treatment data questions in response to the control unit 242 receiving a signal from the weight scale 206 indicating that a fluid bag (e.g., a dialysate bag 102 or a drain bag 112) has been placed on the tray 202.

[0133] The user input treatment parameters captured by microphone 241 may be received by control unit 242 and transmitted to one or more remote computing devices. For example, speaker 240 of basin 204 may be controlled to emit information regarding the clarity of effluent drained from the patient during the draining phase, the concentration of the dialysate used for the filling phase, the expiration date of the dialysis fluid used for the filling phase, the start time of the filling phase, the end time of the filling phase, the volume of dialysate to be provided to the patient during the filling phase, and the clarity of the dialysate used for the filling phase, and the user's response may be captured by microphone 241 and processed by control unit 242 of basin 204.

[0134] In addition, the user may use microphone 241 to provide auditory instructions for controlling one or more elements of basin 204, such as weight scale 206, heating elements 250, 252, and effluent sensor 248. The user's auditory instructions for controlling one or more components of basin 204 may be captured by microphone 241 and transmitted to control unit 242, which controls the corresponding components of basin 204 in response to the user's auditory instructions. Using microphone 241 to capture treatment data and user instructions is particularly useful for users of system 116 who have visual impairments that prevent the user from being able to see and interact with graphical displays.

[0135] As previously described, the speaker 240 on the basin 204 can be used to audibly sound warnings or alarms generated by the control unit 242. Using the speaker 240 to provide audible warnings and alarms in addition to or in lieu of visual warnings (e.g., displayed on the graphical display 238) is particularly beneficial for users with visual impairments that prevent the user from seeing the warnings displayed on the graphical display.

[0136] The control unit 242 (e.g., a microprocessor) of the basin 204 is connected to the weight scale 206, the leak detector 234, the effluent sensor 248, the heating elements 250, 252, the graphic display 238, the speaker 240, and the microphone 241, so that the control unit 242 can receive signals from these components of the system and send signals to these components to control the operation of the basin 204 components and record treatment data. For example, in response to receiving one or more signals (e.g., from the weight scale 206 or the leak detector 234), the control unit 242 can control the graphic display 238 to issue a visual alarm and / or control the speaker 240 to issue an audible alarm.

[0137] The control unit 242 can receive treatment data from various sensors of the basin 204, including the weight scale 206, the leak detector 234, and the effluent sensor 248, as well as user input data received from the graphical display 238 and the microphone 241. In some embodiments, the control unit 242 automatically transmits the treatment data received from the sensors 206, 234, 248, the graphical display 238, and / or the microphone 241 to one or more remote computing devices. For example, the control unit 242 can transmit the received treatment data to a cloud computing device for storage. In some embodiments, the control unit 242 transmits the received treatment data to one or more remote computing devices for display on the remote computing devices. For example, the control unit 242 can transmit the received treatment data to a patient's mobile device for display on the patient's mobile device. In some examples, the control unit 242 transmits the received treatment data to a remote computing device operated by a medical staff assisting the treatment for display at the remote computing device. In some embodiments, the treatment data is wirelessly transmitted by the control unit 242 to the one or more remote computing devices in real time.

[0138] In some embodiments, the control unit 242 processes the received treatment data to generate a treatment report. The treatment report generated by the control unit 242 may include one or more of the following: the drain start time, the drain end time, the amount of fluid drained during treatment, the clarity of the effluent drained during treatment, the weight of the filled drain bag 112 (e.g., as measured by the weight scale 206), the time elapsed between drain bag checks, the dwell time, the volume of dialysate exchanged during treatment, the dialysate temperature, the fill start time, the fill end time, the initial treatment start time (e.g., the same day), the final treatment end time (e.g., the same day), and the total number of cycles performed in a day. In some embodiments, the treatment report generated by the control unit 242 is wirelessly transmitted to one or more remote computing devices. For example, the control unit 242 can be configured to automatically transmit the treatment report to one or more remote computing devices (e.g., a remote storage device and / or a remote computing device of a medical staff member or patient) at a predetermined time each day. In some embodiments, the control unit 242 stores the treatment report in a portable memory device (e.g., a USB device) coupled to the ports 274, 276 of the basin.

[0139] Fig.151 is a flow chart illustrating a method 1500 for detecting fluid leakage from a drain bag during PD therapy. Prior to performing a drain phase of a PD therapy cycle, a fluid bag (e.g., drain bag 112) is positioned on a tray (e.g., tray 202) coupled to a basin device (e.g., basin 204) (1502). The fluid bag is fluidly coupled to the patient's peritoneal cavity (e.g., using transfer device 108 and fluid line 114).

[0140] Once the fluid bag is positioned on the tray, effluent flows into the fluid bag during PD treatment (1504). For example, during the drainage phase of PD treatment, fluid can flow from the patient's peritoneal cavity into the fluid bag. In some embodiments, fluid flows into the fluid bag via gravity (e.g., as in Figure 1 shown in ).

[0141] As described above, the tray includes indicia (e.g., contrast text 222) and / or sensors (e.g., effluent sensor 248) that can be used to determine the clarity of the fluid flowing into the fluid bag. In some embodiments, the basin includes a load cell (e.g., weight scale 206) to measure the weight of the fluid flowing into the fluid bag.

[0142] If a leak occurs in the fluid bag when the fluid flows into the fluid bag positioned on the tray, a leak sensor (e.g., leak detector 234) coupled to a surface of the basin device detects the leak (1506). For example, in some embodiments, the tray supporting the fluid bag includes one or more openings (e.g., opening 210) or channels (e.g., central channel 212) to direct fluid leaking from the fluid bag on the tray into the basin. In some embodiments, the tray has a curved profile to direct fluid leaking onto the tray to a central channel (e.g., central channel 212) in the tray and into the basin. In some embodiments, the leak detector is a humidity detector, and contact between the leaking fluid in the basin and the leak detector causes the leak detector to identify the leak and transmit a signal indicating the presence of a leak to a control unit (e.g., control unit 242). In some embodiments, the basin defines a chamber (e.g., chamber 236) containing the leaking fluid, and an inner surface (e.g., surface 246) of the basin is inclined to direct the fluid contained in the basin to the leak detector.

[0143] In response to receiving a signal from the leak detector indicating that a leak has occurred, the control unit of the basin device (e.g., control unit 242) automatically transmits treatment data including data indicating that a fluid bag leak has occurred to the remote computing device (1508). For example, the control unit may wirelessly transmit the treatment data to one or more computing devices to store or display the treatment data at the one or more remote computing devices. In some embodiments, the treatment data received by the control unit, including the data received from the leak detector, is transmitted from the control unit of the basin to the remote computing device in real time. The treatment data transmitted from the control unit to the remote computing device may include one or more of the following: a drain start time, a drain end time, an amount of fluid drained during treatment, a clarity of effluent drained during treatment, a weight of a filled drain bag 112 (e.g., as measured by a weight scale 206), a time elapsed between drain bag checks, a dwell time, a volume of dialysate exchanged during treatment, a dialysate temperature, a fill start time, a fill end time, an initial treatment start time (e.g., that day), a final treatment end time (e.g., that day), and a total number of cycles performed in a day.

[0144] Fig.16 is a block diagram of an example computer system 400. For example, referring to Figure 2 , the control unit 242 of the basin system 116 can be an example of the system 400 described herein. The system 400 includes a processor 410, a memory 420, a storage device 430, and an input / output interface 440. Each of the components 410, 420, 430, and 440 can be interconnected, for example, using a system bus 450. The processor 410 is capable of processing instructions for execution within the system 400. The processor 410 can be a single-threaded processor, a multi-threaded processor, or a quantum computer. The processor 410 is capable of processing instructions stored in the memory 420 or on the storage device 430. The processor 410 can perform operations such as obtaining a signal from a sensing element (e.g., Figure 8 The operation of receiving signals from the sensing elements (the leak detector 234, the weight scale 206, and the effluent sensor 248 shown in FIG. 2 ) and transmitting the signals received from the sensing elements to a remote computing device or storage device.

[0145] Memory 420 stores information within system 400. In some implementations, memory 420 is a computer readable medium. For example, memory 420 may be a volatile memory unit or a non-volatile memory unit. In some implementations, memory 420 stores data structures. In some implementations, multiple data structures are used.

[0146] The storage device 430 can provide mass storage for the system 400. In some embodiments, the storage device 430 is a non-transitory computer-readable medium. The storage device 430 may include, for example, a hard disk device, an optical disk device, a solid-state drive, a flash drive, a tape, or some other mass storage device. The storage device 430 may alternatively be a cloud storage device, for example, a logical storage device including multiple physical storage devices distributed on a network and accessed using the network.

[0147] The input / output interface 440 provides input / output operations for the system 400. In some embodiments, the input / output interface 440 includes one or more of a network interface device (e.g., an Ethernet card), a serial communication device (e.g., an RS-232 IO port), and / or a wireless interface device (e.g., an 802.11 card, a 3G wireless modem, a 4G wireless modem, a 5G wireless modem, or better). In some embodiments, the input / output device includes a device configured to receive input data and send output data to other input / output devices, such as a keyboard, a printer, and a display device 138. In some embodiments, mobile computing devices, mobile communication devices, and other devices are used.

[0148] In some embodiments, system 400 is a microcontroller. A microcontroller is a device that contains multiple components of a computer system in a single electronic package. For example, a single electronic package may contain a processor 410, a memory 420, a storage device 430, and an input / output interface 440.

[0149] Despite Fig.16 An example processing system has been described in the specification, but embodiments of the subject matter and functional operations described above may be implemented in other types of digital electronic circuits, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or a combination of one or more thereof. Embodiments of the subject matter described in this specification may be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a tangible program carrier, such as a computer-readable medium, for execution by a processing system or for controlling the operation of a processing system. A computer-readable medium may be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter that effects a machine-readable propagated signal, or a combination of one or more thereof.

[0150] The term "computer system" may encompass all devices, apparatuses, and machines for processing data, including, for example, a programmable processor, a computer, or multiple processors or computers. In addition to hardware, a processing system may also include code that creates an execution environment for the computer program in question, for example, code constituting processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of these.

[0151] A computer program (also referred to as a program, software, software application, script, executable logic, or code) can be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program may be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files storing one or more modules, subroutines, or partial codes). A computer program may be deployed to execute on one computer or on multiple computers deployed at one site or distributed at multiple sites and interconnected by a communication network.

[0152] Computer-readable media suitable for storing computer program instructions and data include all forms of nonvolatile or volatile memory, media, and storage devices, including, for example, semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks, such as internal hard disks or removable magnetic disks or tapes; magneto-optical disks, and CD-ROM and DVD-ROM disks. The processor and memory may be supplemented by, or incorporated in, special purpose logic circuitry. The components of the system may be interconnected by any form or medium of digital data communication, such as a communication network. Examples of communication networks include local area networks ("LANs") and wide area networks ("WANs"), such as the Internet.

[0153] A number of embodiments have been described. However, it will be appreciated that various modifications can be made without departing from the spirit and scope of the present disclosure.

[0154] For example, although the basin system 116 has been described as being used during CAPD treatment, the basin system 116 may also be used during automated peritoneal dialysis (APD) treatment. During APD treatment, an automated PD machine, known as a PD cycler, controls the entire PD process so that it can be performed at home, typically overnight, without the involvement of clinical staff. Many PD cyclers are designed to automatically infuse, retain, and drain dialysate into and from a patient's peritoneal cavity. APD treatment typically lasts several hours, typically beginning with an initial drain cycle to clear the peritoneal cavity of used or spent dialysate.

[0155] Fig.17 An exemplary PD cycler 902 is shown positioned on a cart 904. The PD cycler 902 includes a housing 906, a door 908, and a cassette interface that contacts a disposable PD cassette when the cassette is disposed in a cassette compartment formed between the cassette interface and the closed door 908. A dialysate bag 922 is suspended on fingers on the side of the cart 904. The dialysate bag 922 is connected to the cassette via a dialysate bag line 926. The dialysate bag line 926 can be used to transfer dialysate from the dialysate bag 922 to the cassette during the fill phase of an APD treatment cycle. A patient line 930 and a drain line 932 are connected to the cassette. The patient line 930 can be connected to the abdomen of the patient via a catheter and can be used to transfer dialysate back and forth between the cassette and the patient's peritoneal cavity during use. The drain line 932 can be connected to a drain bag 912 positioned on the basin system 116 and can be used to transfer dialysate from the cassette to the drain bag 912 during use.

[0156] As described above, the basin system 116 can be used to measure and record one or more treatment data regarding a PD treatment, such as a drain start time, a drain end time, an amount of fluid drained during treatment, clarity of effluent drained during treatment, residence time, and a volume of dialysate exchanged during treatment. In addition, as described herein, the basin system 116 can be used to detect and contain any leaks in the drain bag 912 that occur during treatment. The treatment data collected by the basin system 116 can be used to confirm the accuracy of similar treatment data collected by the cycler 902, and can be used to calibrate the cycler 902. In some embodiments, the basin system 116 used in conjunction with the cycler 902 during APD treatment has a larger tray 202 and basin 204 than the system 116 used during CAPD treatment to accommodate a larger and / or greater number of drain bags used during APD treatment.

[0157] In some embodiments, the drain bag 912 used during APD is connected to a hook on the cart 904 to support the drain bag 912, and the basin system 116 is positioned below and in contact with the drain bag 912. In some embodiments, the basin system 116 used for APD treatment does not include a heating system (e.g., conductive core elements 218, 220 and heating elements 250, 252) because the dialysate is automatically heated by the cycler 902.

[0158] Although the heating elements 250, 252 have been described as being automatically activated and deactivated based on signals received from the weight scale 206, other means of controlling the heating elements 250, 252 are possible. For example, in some embodiments, the heating elements 250, 252 are controlled based on user input received by the control unit 242. For example, a user can use the graphical display 238 or microphone 241 of the basin 204 to provide instructions for activating or deactivating the heating elements 250, 252. In some embodiments, a user can use the graphical display 238 or microphone 241 of the basin 204 to set the temperature of the heating elements 250, 252. In some embodiments, the system includes a mechanical switch that is activated when a predetermined amount of force is placed on the tray 202, such as when the dialysate bag 102 is placed on the tray 202, and the control unit 242 activates the heating elements 250, 252 in response to the activation of the mechanical switch.

[0159] In some embodiments, magnets are positioned within the basin 204, and the system 116 includes a Hall effect sensor to control activation of the heating elements 250, 252. For example, when a threshold force is applied to the tray 202 (e.g., by positioning the dialysate bag 102 on the tray 202), the conductive core elements 218, 220 are lowered into proximity with the magnets in the basin 204, which causes the Hall effect sensor to transmit a sensor signal to the control unit 242. In response to receiving a signal from the Hall effect sensor indicating that a force has been applied to the tray 202, the control unit 242 activates the heating elements 250, 252 to heat the conductive core elements 218, 220.

[0160] In some embodiments, the system 116 includes one or more ultrasonic range detectors and / or optical or laser detectors that are configured to measure the distance between the tray 202 and the bottom surface 246 of the basin 204 in order to control the activation of the heating elements 250, 252. For example, when a threshold force is applied to the tray 202 that causes the tray 202 to be lowered to within a threshold distance of the bottom surface 246 of the basin 204 (e.g., by positioning the dialysate bag 102 on the tray 202), the ultrasonic, optical, or laser sensor transmits a signal to the control unit 242. In response to receiving the signal from the ultrasonic, optical, or laser sensor, the control unit 242 activates the heating elements 250, 252 to heat the conductive core elements 218, 220. Similarly, in some embodiments, the system 116 includes one or more optical detectors configured to detect an air gap between the bottom of the tray 202 and the bottom surface 246 of the basin 204, and when force is applied to the tray 202 to lower the tray 202 into contact with the bottom surface 246 of the basin 204 (e.g., by positioning the dialysate bag 102 on the tray 202), the optical detector transmits a signal indicating contact between the tray 202 and the basin 204 to the control unit 242. In response to receiving the signal indicating contact between the tray 202 and the basin 204 from the optical detector, the control unit 242 activates the heating elements 250, 252 to heat the conductive core elements 218, 220.

[0161] Although the tray 202 has been shown as including two conductive wick elements 218, 220, other numbers of conductive wick elements 218, 220 may be used. Additionally, although the basin 204 has been shown as having two heating elements 250, 252, other numbers of heating elements may be used.

[0162] Although the tray has been shown as having two handles 214, 216, the tray may alternatively include a single handle or three or more handles. In addition, although the handles 214, 216 are shown as being formed into the tray 202, one or more handles may be coupled to the surface of the tray.

[0163] Although basin system 116 has been shown as including both contrasting text 222 and effluent sensor 248, in some implementations, system 116 includes contrasting text 222 and does not include effluent sensor 248. In some implementations, effluent sensor 248 is included and contrasting text 222 is not included.

[0164] Additionally, while the effluent sensor has been described as an optical sensor, in some embodiments, the effluent sensor 248 is an ultrasonic sensor. The ultrasonic effluent sensor 248 can be used to detect the presence of one or more foreign matter in the effluent, such as fibrin or other particles in the effluent in the drain bag 112. In response to detecting foreign matter in the effluent using the ultrasonic effluent sensor 248, a signal indicating the presence of foreign matter in the effluent can be transmitted to the control unit 242, which in response can cause the graphical display 238 and / or the speaker 240 of the basin 204 to generate an alarm indicating the foreign matter in the effluent.

[0165] Although the effluent sensor 248 has been described as being activated in response to user input, in some embodiments, the effluent sensor 248 is automatically operated by the control unit 242 without user input. For example, in response to receiving a signal from the weight scale 206 indicating that a predetermined amount of time has passed since the weight scale 206 detected any weight increase, indicating that the drain cycle is complete, the control unit 242 can activate the effluent sensor 248 to automatically scan the effluent 242 contained in the drain bag 112 and transmit the results to the control unit 242. In some embodiments, the effluent sensor 248 is configured to scan the effluent at predetermined intervals periodically throughout the drain process (e.g., every 10 to 15 minutes during the drain process).

[0166] Although the leak detector 234 has been shown as being formed by two metal rings 231, 233, other types of leak detectors may be used to detect fluid leaking into the basin 204. For example, in some embodiments, the leak detector includes two probes that serve as a positive terminal and a negative terminal. When a conductive fluid, such as dialysate or effluent, leaks into the chamber 236 and contacts the two probes of the leak detector 234, the leaking fluid bridges the gap between the probes and allows current to flow from the positive terminal to the negative terminal to complete the circuit. In response to the completion of the circuit formed by the leak detector 234, the leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., a control unit 242).

[0167] In some embodiments, the basin 204 includes a leak detector 234 having a pair of ultrasonic heads positioned relative to each other (e.g., formed between the scale 206 and the bottom surface 246 of the chamber 236), and when leaking fluid flows into the chamber and passes between the ultrasonic heads, the leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., the control unit 242).

[0168] In some embodiments, the system 116 includes a leak detector 234 having a rotameter with an optical sensor that detects fluid as it moves a float in a chamber of the leak detector 234. In response to the optical sensor detecting that the float has moved within the chamber, the leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., the control unit 242).

[0169] In some embodiments, leak detector 234 includes a microphone and detects a leak in basin 204 based on control unit 242 receiving a sound recording from the leak detector and detecting that the recording includes noise generated by fluid flowing through leak detector 234 .

[0170] In some embodiments, the leak detector 234 includes a turbine or wheel, and when the fluid leaking into the basin flows through the turbine or wheel of the leak detector 234, it causes the wheel or turbine to rotate. In response to the rotation of the wheel or turbine, the leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., control unit 242).

[0171] In some embodiments, the leak detector 234 includes a piezoelectric sensor, and when fluid leaking into the basin 204 contacts the piezoelectric sensor of the leak detector 234, the leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., the control unit 242).

[0172] In some embodiments, leak detector 234 includes an optical flow sensor that generates a laser beam, and when fluid leaking into basin 204 flows through the leak detector, the laser beam is interrupted, which is detected by the optical flow sensor. In response to the optical flow sensor detecting the interruption of the laser beam, leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., control unit 242).

[0173] In some embodiments, leak detector 234 includes a thermal sensor that detects a change in temperature when fluid leaks into basin 204. For example, the thermal sensor can detect when the leaking fluid lowers the temperature of a hot spot in the basin. In response to the thermal sensor detecting a temperature change caused by the leaking fluid, leak detector 234 transmits a signal indicating the presence of a leak to a computing device (e.g., control unit 242).

[0174] Although the rack 104 for hanging the dialysate bag 102 during the fill phase of CAPD therapy has been shown as being separate from the basin system 116 , in some embodiments, the rack for hanging the dialysate bag is integrated into the basin 204 of the basin system 116 .

[0175] In addition, although the basin system 116 has been shown as being placed on the floor next to the patient 110, the basin system 116 can be positioned on other surfaces during treatment. For example, the basin system 116 can be positioned on a chair or table near the patient 110 during treatment so that the basin system 116 is positioned within reach of the patient 110.

[0176] Although the flow sensor 120 has been described as transmitting sensor data to the control unit 242 by interfacing with the ports 274, 276 on the basin 204, in some embodiments, the flow sensor 120 is wirelessly coupled to the control unit 242 of the basin 204 and transmits the data wirelessly (e.g., using Bluetooth or another near field communication connection) to the control unit 242. In some embodiments, the sensor data is transmitted from the flow sensor 120 to the control unit 242 in real time.

[0177] Additionally, while the volume of fluid provided to the patient during the filling phase has been described as being measured using the flow sensor 120, in some embodiments, the amount of fluid provided to the patient 110 during the filling phase of treatment is measured using a load cell coupled to the support 104. For example, at the beginning of the filling phase, the dialysate bag 102 can be suspended from or otherwise attached to the load cell attached to the support 104. As fluid flows from the dialysate bag 102 to the patient 110 during the filling phase of treatment, and as a result, the weight of the dialysate bag 102 decreases, these changes in weight can be measured by the load cell on the support 104 and transmitted to the control unit 242. Based on this decrease in weight measured by the load cell on the support 104, the control unit 242 can determine the volume of dialysate provided to the patient during the filling phase of treatment.

[0178] In addition, although the start time and the end time of the filling phase have been described as being determined based on the data received from the flow sensor 120, other methods of determining the start time of the filling and the end time of the filling can be used. For example, as previously described, the dialysate bag 102 containing fresh dialysate can be placed on the tray 202 for heating by the basin system 116 before starting the filling phase. Once the heating is completed, the dialysate bag 102 is removed from the tray 202 and attached to the bracket 104 to start the filling phase. The weight scale 206 can detect the reduction of the force applied to the tray 202 due to the removal of the dialysate bag 102 from the tray 202 after the heating of the dialysate is completed, and in response to detecting the reduction of the force at the end of the heating, a signal indicating the start time of the filling phase corresponding to the time of the reduction of the force can be sent to the control unit 242. Similarly, after the filling phase is completed, the emptied (or partially emptied) dialysate bag 102 can be returned to the tray 202 for measuring the final weight of the dialysate bag 102. The weight scale 206 may detect an increase in force applied to the tray 202 due to placing an empty dialysate bag 102 on the tray 202 at the end of the filling phase. In response to detecting the increase in force caused by placing an empty dialysate bag 102 on the tray 202 at the end of the filling phase, the weight scale 206 may send a signal to the control unit 242 indicating an end time of the filling phase, the end time corresponding to the time when the increase in force was detected due to placing an empty dialysate bag 102 on the tray 202 at the end of the filling phase.

[0179] Although user input has been described as being received by the control unit 242 via the graphical display 238 or microphone 241 of the basin 204, in some embodiments, the user may use a remote computing device, such as a mobile device, to transmit data to the control unit 242. For example, in some embodiments, the user may interact with an application on the mobile device to provide treatment data to the control unit 242 of the basin 204 and to provide commands to the control unit 242 for controlling one or more components of the basin 204. For example, the user may interact with the application on the computing device to provide data such as dialysate concentration, dialysate expiration date, dialysate volume exchanged during treatment, fill start time, fill end time, dwell time, drain start time, drain end time, amount of fluid drained during treatment, clarity of effluent drained during treatment, and the like.

[0180] Furthermore, while the alarms, messages, and warnings have been described as being provided to the user by the graphical display 238 and the speaker 240 of the basin 204, in some embodiments, the control unit 242 may additionally or alternatively send the alarms, messages, and warnings to one or more remote computing devices. For example, the control unit 242 may send the alarms, messages, and warnings as push notifications on the user's mobile device. In some embodiments, the control unit 242 transmits the alarms, messages, and warnings to the user's computing device for display in an application operating on the user's computing device.

[0181] Although the components of the basin 204 have been described as being powered by a rechargeable battery, other power sources may be used to provide power to the basin 204. For example, the basin 204 may be powered directly by a power source by connecting the power source to a power adapter 270 on the back of the basin 204 via a power cable.

[0182] Although the control unit 242 has been described as transmitting the treatment data to one or more remote computing devices for storage, in some embodiments, the treatment data is additionally or alternatively stored on a local storage device of the basin system 116 .

[0183] Although basin system 116 has been described as supporting both dialysate bag 102 and drain bag 112 during PD treatment, basin system 116 may alternatively be used to support only dialysate bag 102 during treatment or only drain bag 112 during treatment.

[0184] Although basin system 116 has been described as being used as part of PD system 100 during PD treatment, basin system 116 may also be used during other blood treatments including, but not limited to, hemodialysis (HD) treatment, hemofiltration (HF) treatment, and hemodiafiltration (HDF).

[0185] Fig.18 An example blood treatment system 800 is shown for performing one or more types of blood treatments, including HD, HF, and HDF treatments. Fig.18 As can be seen in FIG. 8 , a blood treatment system 800 includes a blood treatment machine 802 to which a disposable blood component set 804 forming a blood circuit is connected.

[0186] The blood treatment system 800 includes a fluid regulation system 806 that is fluidly coupled to the blood treatment machine 802 and generates fluid used during treatment, such as dialysis fluid, which can be provided to the blood treatment machine 802.

[0187] The blood treatment system 800 further comprises a waste line 808 connected at a first end to the fluid circuit of the blood treatment machine 802 and at a second end to a drain bag 812 .

[0188] During treatment, the arterial and venous patient lines of the disposable blood component kit are connected to the patient, and blood circulates through the various blood lines and components of the blood component kit. Meanwhile, fresh dialysate is generated by fluid regulating system 806, and flows to the dialyzer of the dialysis treatment machine via fluid lines from fluid regulating system 806. During treatment, toxins are removed from the patient's blood and collected in the dialysate flowing through the dialyzer. Then, the filtered blood is returned to the patient, and the used dialysate leaving the dialyzer flows back to the fluid regulating system 806. The sorbent box 814 of fluid regulating system 806 removes (e.g., filters out) the toxic substances collected in the used dialysate to produce "regenerated" dialysate (e.g., clean, unregulated dialysate) that flows out of the sorbent box 814. The regenerated dialysate leaving the sorbent box 814 is further regulated by the fluid regulating system 806 to meet acceptable physiological characteristics, and is then pumped back to the blood treatment machine 802 as "fresh" dialysate.

[0189] Once the treatment is completed, the spent dialysate (and any additional fluid removed from the patient) is drained from the fluid circuit of the blood treatment machine 802 and the fluid regulation system 806 through the waste line 808 and into the drain bag 812. For example, one or more pumps of the blood treatment machine 802 and / or the fluid regulation system 806 may be operated to draw fluid from the fluid circuit of the blood treatment machine 802 and / or the fluid regulation system 806, through the waste line 808, and into the drain bag 812.

[0190] from Fig.18 As can be seen in FIG. 1 , the drain bag 812 of the blood treatment system 800 can be supported by the corresponding basin system 116 during treatment. For example, the basin system 116 supporting the drain bag 812 can be used to measure the weight of the fluid provided to the drain bag at the end of the treatment (e.g., by using the weight scale 206 of the basin system 116). The basin system 116 can also be used to detect the clarity of the spent dialysate contained in the drain bag 812 (e.g., using the contrast text 222 and / or the effluent sensor 248, as described above). The basin system 116 can also be used to detect whether a leak from the drain bag 812 has occurred during treatment using a leak detector (e.g., leak detector 234) positioned in the basin 204 of the basin system 116.

[0191] In addition, the basin system 116 can be used to record data about the blood treatment and automatically transmit data about the blood treatment to a remote computing device. For example, the basin system supporting the drain bag 812 can record and transmit the amount of spent dialysate drained during the treatment, any leaks from the drain bag 812 detected during the treatment, the clarity of the spent dialysate in the drain bag 812, and the end time of the treatment (e.g., corresponding to the time of the last increase in weight of the drain bag 812 as detected by a weight scale of the basin system 116, such as the weight scale 206). In some embodiments, the treatment data is transmitted from the basin system 116 to one or more remote computing devices in real time. Reference above Figure 2-14 The use of the basin system 116 to record and transmit treatment data is described in detail.

[0192] Although Fig.18 A single basin system 116 is shown used to support a drain bag 812 during HD, HF, or HDF treatment, but in some embodiments, the basin system can be used to support a container of dialysis fluid (or other fluid used by the fluid conditioning system 806 to generate dialysate) during treatment using the blood treatment machine 802. In addition, the basin system 116 used to support the dialysate bag can include a heating system (e.g., conductive core elements 218, 220 and heating elements 250, 252), while the basin system used to support the drain bag 812 does not include a heating system.

[0193] Furthermore, while the basin system 116 has been shown as being separate from the blood treatment machine 802 and the fluid regulation system 806, the basin system may alternatively be included as a subsystem of the blood treatment machine 802 and / or the fluid regulation system 806. For example, one or more basin systems may be attached to the bottom of the blood treatment machine 802 for holding one or more drain bags 812.
