No. 13/494259 of June 12, 2012, filed entitled tion ", which claims its benefits.

  [0002] The present disclosure relates generally to kidney treatment systems, and more particularly to systems and methods for controlling a water treatment device exclusively through a dialysis machine.

  [0003] The human kidney system may fail due to causes such as illness or disability. There are some physiological disruptions in any cause of kidney damage. When kidney damage occurs, it becomes impossible to balance water and minerals and excrete the daily metabolic load. In kidney failure, harmful end products of nitrogen metabolism (urine, creatinine, uric acid, etc.) can accumulate in blood and tissues.

  [0004] Treatment for dialysis is performed for kidney damage and decreased kidney function. Dialysis removes waste, toxins and excess water from the body that would otherwise be removed by a normally functioning kidney in a healthy body. Dialysis treatment as an alternative to kidney function is important for many people because it saves lives. People with kidney problems may not be able to stay alive without at least an alternative to the filtering function of the kidneys.

  [0005] Hemodialysis and peritoneal dialysis are two types of dialysis therapies commonly used for the treatment of loss of renal function. In a hemodialysis procedure, the patient's blood is used to remove waste, toxins and excess water from the patient. The patient is connected to a hemodialysis machine that draws the patient's blood. A catheter or needle is inserted into the patient's circulatory system to connect blood flow to the hemodialysis machine. Blood and dialysate pass through the dialyzer of the hemodialysis machine. The dialyzer can include a semi-permeable membrane that separates blood and dialysate. As the blood passes through the dialyzer of the hemodialysis machine, the dialyzer removes waste, toxins and excess water from the patient's blood. In particular, the toxin is transferred from the blood through the membrane into the dialysate by osmotic pressure. The hemodialysis machine returns this blood to the patient. Large quantities of dialysate, such as about 120 liters, are used to dialyze blood in a single hemodialysis procedure. The spent dialysate is then discarded. The hemodialysis treatment lasts several hours and is typically performed at a treatment center about 3 or 4 times a week.

  [0006] Peritoneal dialysis uses a dialysis solution or "dialysate" that is infused into the abdominal cavity through a catheter implanted in the patient's abdominal cavity. The dialysate contacts the patient's peritoneum in the abdominal cavity. Waste, toxins and excess water travel from the patient's bloodstream through the peritoneum into the dialysate. The transfer of waste, toxins and water from the bloodstream to the dialysate occurs by diffusion and osmosis. That is, an osmotic gradient is generated across the membrane. Spent dialysate is drained from the patient's peritoneal cavity to remove waste, toxins and excess water from the patient. This cycle is repeated.

  [0007] There are various types of peritoneal dialysis therapy, including continuous ambulatory peritoneal dialysis (CAPD), automatic peritoneal dialysis, and continuous flow peritoneal dialysis. CAPD is a manual dialysis procedure that allows the patient to drain the spent dialysate from the abdominal cavity by connecting an implanted catheter to the drain. The patient then attaches the catheter to a bag of fresh dialysate and manually infuses fresh dialysate through the catheter and into the patient's abdominal cavity. The patient disconnects the catheter from the fresh dialysate bag, allowing the dialysate to stay in the abdominal cavity and transfer waste, toxins and excess water from the patient's bloodstream to the dialysate. After the dwell period, the patient repeats the manual dialysis procedure.

  [0008] In CAPD, a patient performs several drain / fill / dwell cycles during the day, for example, about four times a day. A single treatment cycle usually takes about 1 hour. The manual peritoneal dialysis performed by the patient requires considerable time and effort. This inconvenient procedure has considerable room for improvement and enhancement of therapy to improve the patient's quality of life.

  [0009] Automatic peritoneal dialysis (APD) is similar to CAPD in that the dialysis treatment includes a drain / fill / dwell cycle. However, the APD device automatically performs three or four cycles of peritoneal dialysis treatment, usually at night when the patient is asleep. The APD device is fluidly connected to the implanted catheter. The APD device also fluidly connects to a fresh dialysate source or bag and fluid drain.

  [0010] The APD device delivers fresh dialysate from the dialysate source through the catheter into the patient's peritoneal cavity, allowing the dialysate to enter the peritoneal cavity so that waste, toxins and excess water can be transferred from the patient's bloodstream to the dialysate. Be able to stay inside. The APD device then sends spent dialysate through the catheter from the abdominal cavity to the drain. The APD device is typically computer controlled so that the dialysis procedure is performed automatically when the patient is connected to a dialysis machine, for example when the patient is asleep. That is, the APD system automatically and continuously sends fluid into the abdominal cavity and causes it to stay, aspirates fluid from the abdominal cavity, and repeats this procedure.

  [0011] Similar to the manual process, there are several cycles of drain / fill / dwell cycles during APD. “Last fill” is typically used at the end of APD, so that fluid remains in the patient's peritoneal cavity when the patient is disconnected from the dialysis machine for the day. APD eliminates the need for the patient to manually perform the drain, dwell, and fill steps.

  [0012] Frequent dialysis is a part of life for patients with kidney disease. Most peritoneal dialysis patients perform dialysis once a day. Hemodialysis patients usually require dialysis several times a week. There is an increasing need for home dialysis methods so that patients can live as normal as possible. Peritoneal dialysis is usually done at home. Blood treatment therapies such as hemodialysis and hemofiltration are often performed at centers and clinics.

  [0013] Dialysis at home, whether hemodialysis or peritoneal dialysis, increases the difficulty and complexity for the patient. Usually, dialysis is performed using a dialysis machine and a fluid source. The fluid source may be prepared in one or more prepared solution bags, or may be prepared online via a water treatment device and a concentrated additive. In the case of a water treatment device, the dialysis machine and the water treatment device are operated simultaneously in order to successfully perform the treatment. Operating two machines or devices can be difficult, especially for elderly patients or those who cannot move, which may not be easy to observe and / or operate both devices quickly. There is. Viewing information on two devices and / or entering information into two devices can be cumbersome. Both the dialysis machine and the water treatment device generate data that may be desirable to store for analysis. This data must be accurate and timely and provide sufficient detail.

  [0014] Accordingly, a water treatment device is integrated with a hemodialysis machine to centralize control of both machines or devices and to allow easy exchange of data with both machines or devices There is a need for a dialysis system.

  [0015] The systems and methods of the present disclosure integrate the operation of a dialysis machine and a water treatment device so that a user essentially operates the water treatment device from the dialysis machine. That is, the user interface with the water treatment apparatus is a user interface that controls the dialysis machine. Although the water treatment device may have its own small user interface, the main control of the water treatment device is performed via a dialysis machine. It also forwards data from both machines to a central repository maintained by the care provider, providing treatment data reports to both the dialysis machine and water treatment equipment to the clinician, integrated with payment and ordering systems, and consumables It is also contemplated to track the use of the system, deliver consumables as needed, and inspect and maintain the machines on the system network. To this end, in one embodiment, the dialysis machine is in data flow communication with the water treatment device via Ethernet or other wired communication. The dialysis machine is in communication with the system or network. In this way, data from the water treatment device can be transmitted to the network or system via the dialysis machine. The system or network can similarly send operational instructions and software upgrades to the water treatment device via the dialysis machine.

  [0016] Dialysis machines include home hemodialysis (HD) machines, home peritoneal dialysis (PD) machines, home hemofiltration (HF) machines, home hemodiafiltration (HDF) machines, and home continuous kidney replacements (CRRT) machines, including but not limited to home therapy machines. Although renal therapy is one focus of the present disclosure, the present disclosure also contemplates the integration of any home fluid delivery therapy, such as home drug delivery therapy or nutrition therapy. In various embodiments, home treatment uses medical fluids that can be generated online or in use starting from a source of purified water, such as ultrapure water, as the term is understood in the art. Was any type of therapy. For example, PD is usually performed using a bag of dialysate, but instead, an on-line PD solution originating from a source of ultrapure or sterile water is generated and optionally dextrose. It is also contemplated to add PD concentrates such as glucose and glucose concentrates.

  [0017] It is also contemplated that home therapy is a nutritional therapy that is used as a basis for preparing a nutrient solution that delivers purified water from a water treatment device to a patient. In any situation, all control of the water treatment device is used to control a home treatment machine, which in one embodiment is a blood treatment home treatment machine, a PD home treatment machine, or a home nutrition treatment machine. Is done through the same user interface.

  [0018] It is also contemplated that the home medical device system transfers the treatment prescription to a home therapy machine. A doctor's prescription for the kidney or other type of home treatment is created. Based on the physician's prescription, the clinician can remotely select supplies to be sent to the patient's home, including supplies for both home therapy machines and water treatment devices. The clinician can also remotely set operating parameters for operating both the home therapy machine and the water treatment device. The operating parameters of both the home therapy machine and the water treatment device are transmitted to the home therapy machine. The operating parameters of the home therapy machine are stored in the memory of this therapy machine. The operating parameters of the water treatment device are transferred to the water treatment device by the home treatment machine and stored in the memory of the water treatment device.

  [0019] In the systems and methods of the present disclosure, firmware upgrades for home therapy machines and water treatment devices can also be performed via the home therapy machine. Once the upgraded firmware is generated, this firmware is sent to the home therapy machine. If the new firmware is for a home treatment machine, it is installed on the home treatment machine. If the new firmware is for a water treatment device, the home therapy machine transfers the new firmware to the water treatment device and is installed at the water treatment device. In certain jurisdictions, users may need to accept software upgrades, whether for home treatment machines or water treatment equipment. In either case, the user intends to be able to accept this new firmware in the home therapy machine user interface, whether for a home therapy machine or a water treatment device.

  [0020] It is also contemplated that the motion prescription and new firmware be provided with a tag that specifies whether the home therapy machine or the water treatment device receives the motion command or firmware. Alternatively, the instructions and firmware appear essentially as content specific to either a home treatment machine or a water treatment device, or have content specific to either a home treatment machine or a water treatment device It may be. In the latter case, the home treatment machine may determine whether the home treatment machine itself accepts the instruction or firmware upgrade or forwards it to the water treatment device based on the detected unique characteristics. it can. Here, no additional tags are required.

For example, M hemodialysis machines 100, N hemofiltration machines 100, O hemodiafiltration machines 100, P peritoneal dialysis machines 100, Q pieces connected to the server 118 and operating with the system 110. There may be a home drug delivery machine 100 and R home nutrition therapy machines 100. The number of M to R may be the same or different, and may be zero, one, or a plurality.

  [0047] In the illustrated embodiment, the home treatment machine 100 receives purified water from the water treatment device 10 at its front end. One suitable water treatment device 10 is “Water Purification System And Method” filed Apr. 25, 2011, which is hereby relied upon in its entirety and incorporated herein by reference in its entirety. US Patent Application Publication No. 2011/0197971. In one embodiment, the water treatment device 10 outputs ultrapure water as understood in the art as a term. Ultrapure water can pass through one or more filters, such as an ultrafiltration membrane or a dialyzer that produces water of the quality of an injectable solution or drug or close to it. This injectable quality water is then mixed with one or more dry, liquid or slurry concentrates to (i) an injectable replacement solution for HF or HDF, (ii) a PD solution , (Iii) a drug for injection, or (iv) a nutrient solution for injection.

  [0048] In the system 110, in addition to the water treatment device 10, the home treatment machine 100 operates with other devices such as a blood pressure monitor 104, a scale such as a wireless scale 106, and a wireless tablet user interface 122. It is shown. The home treatment machine 100, in one embodiment, connects to the server 118 wirelessly via the modem 102. Each of these components, including the water treatment device 10, is generally located within the patient's home, as shown by the dashed lines in FIG. 1A. Any one, any plurality, or all of the components 10, 104, 106, and 122 can communicate with the home treatment machine 100 in a wired or wireless manner.

Data transfer of water treatment equipment
[0057] In one embodiment, the home therapy machine 100 performs a home procedure, such as home hemodialysis for the patient at the patient's home, and then the results of the procedure are used to manage the patient's health and well-being. Report to clinicians, doctors and nurses. The result of the treatment includes data supplied from the water treatment device 10 to the home treatment machine 100. Data for the water treatment device 10 includes, for example, the total volume of water delivered, the quality of water delivered (eg, chlorine content), for example, to obtain component exchange information, and the water treatment device 10 during treatment The number of times water has been delivered to the treatment machine 100 (this data may be monitored by the machine 10 or the machine 100), the average flow rate of water delivered, an alarm generated by the water treatment device 10 during the procedure, or Warnings, and / or time or number of cycles executed during the procedure, and the like.

  [0058] The home treatment machine 100 writes the log file using, for example, a Linux operating system. The log file is a re-documented data of the relevant home treatment machine 100 and the relevant water treatment device 10 being treated. The log file can include any one or more of Extensible Markup Language (XML), Comma Separated Format (CSV), or a text file. The log file is arranged in a file server box of software of the home treatment machine 100. Data that is not transmitted to the machine 100 is intended to be stored in the water treatment device 10. Alternatively, such data can be obtained via an Ethernet data connection to the water treatment device 10, or can be downloaded via other data connections or storage media. For example, the service person can access the additional data via a laptop connected to the water treatment device 10 via an Ethernet connection. Alternatively, the home treatment machine 100 may function as a data transfer connection between the water treatment device 10 and an authorized system client as described herein to retrieve additional data remotely from the water treatment device 10. it can.

  [0059] The home therapy machine 100 transfers data, such as data for the water treatment device 10, between the modem 102 and the system hub 120 using, for example, connectivity services over the Internet. In one embodiment, each patient's home is provided with a dedicated line for connecting the home treatment machine 100 to the connectivity server 118 via the modem 102. In one embodiment, the home treatment machine 100 accesses the Internet using a separate modem 102, for example 3G, 4G or 5G. The modem 102 uses an Internet service provider (ISP) such as Vodafone (trademark). In one embodiment, a connectivity agent 114 developed by a connectivity service provider (eg, a provider of connectivity server 118) is installed on the home treatment machine 100 and runs on a primary control processor (ACPU) 112. One suitable connectivity service is provided by Axeda ™. The connectivity service provides a securely managed connection 116 between the medical device and the connectivity server 118.

  [0060] The connectivity agent 114 allows the home therapy machine 100 to connect to the connectivity server 118 and transfer data, such as data for the water treatment device 10, to and from the connectivity server 118. it can. A connectivity service that operates through the agent 114 and the server 118 ensures that the connection to the machine 100 is secure, ensures that the data passes correctly through the firewall of the machine 100, and a data or system crash To verify that the connectivity server 118 is communicating with the correct home treatment machine 100 and to ensure that.

  [0061] In one embodiment, the home treatment machine 100 can connect to the connectivity server 118 only when the connectivity agent 114 is turned on. The connectivity agent 114 is turned off during the procedure in which the machine 100 and the water treatment device 10 are functioning and during the sterilization after the procedure. This prevents the home therapy machine 100 from communicating with any entity to send and receive data during treatment and sterilization, or when the machine 100 is powered on or operating. The ACPU 112 turns on the connectivity agent 114 when the home therapy machine 100 is idle, for example after treatment and post-sterilization is complete. In one embodiment, connectivity agent 114 is turned off only during treatment (including pre-processing). Next, the connectivity agent 114 retrieves the log file from the home treatment machine 100 and transfers data such as data of the water treatment device 10 to the connectivity server 118 using the connectivity service. The connectivity service routes the data packet to the appropriate destination, but in one embodiment does not modify, access or encrypt the data.

  [0062] In the system 110 of FIG. 1A, the connectivity service via the connectivity server 118 can communicate data to various locations via the system hub 120, service portal 130, and web portal 150. The connectivity server 118 allows service personnel 132a-132n and / or clinicians to use the appropriate home therapy machine 100 and various assets on the network such as the 3G, 4G or 5G modem 102, as well as the machine or modem serial number. It is possible to track and retrieve information related to those assets. The connectivity server 118 is used to receive firmware upgrades approved by the service personnel supervisor 134 and obtained remotely via the service portal 130, and authorized home treatment machines 100 and associated water treatment. It can also be provided to the device 10.

  [0063] In one embodiment, the connectivity agent 114a (not shown) may be installed on the water treatment device 10 as well as installed on the home treatment machine 100. If the home treatment machine 100 is unable to communicate with the system hub 120 and the system hub 120 needs to communicate with the water treatment device 10, the water treatment device 10 may communicate with the system hub via the connectivity agent 114a. 120 can communicate directly. Alternatively, the connectivity agent 114a may be installed in a separate device or unit (not shown) that can be selectively connected to the water treatment device 10 so that, for example, the home treatment machine 100 communicates with the system hub 120. In the case of loss, the water treatment device 10 may be converted to communicate directly with the system hub 120 again.

Inspection of water treatment equipment
[0064] In one embodiment, the home treatment machine 100 allows service personnel to access both the home treatment machine 100 and the water treatment device 10 in the field and / or remotely to diagnose and troubleshoot both. Can be operated in service mode. For example, a patient may be able to call a service person or technician if a problem occurs with the water treatment device 10 or if its components, such as a chemical pack, are used up. The patient and / or service personnel can then verify the water treatment device 10 via the home treatment machine 100 and the service technician can remotely verify the settings and functions of the water treatment device 10 for the various components of the water treatment device 10. To be in service mode. In one embodiment, the system 110 interrupts the procedure to improve safety while the service technician is engaged with the machine 100. For example, a service person may be able to log on to the device 10 via the machine 100 while the procedure is paused. Alternatively, the machine 100 must be idle or powered off to allow service personnel access to the machine 100 and / or the device 10. Alternatively, it may only be necessary to disconnect the machine 100 from the patient to allow service personnel to access the machine 100 and / or the device 10.

  [0065] Once accessed, the service technician remotely examines a log file stored on the home treatment machine 100 to determine the cause of the error that the water treatment device 10 is experiencing on the water treatment device 10. And can be taken out. In addition, the service person may check whether a related sensor such as a pressure sensor of the water treatment apparatus 10 is operating properly and / or whether a valve or a pump of the water treatment apparatus 10 is operating properly. In some cases, the valve can be switched to operate the pump. The service representative does this by sending a command to the home treatment machine 100. The home treatment machine 100 recognizes that this command is for the water treatment device 10 and passes this command to the treatment unit / memory of the water treatment device 10 so that the water treatment device 10 can operate appropriately. Cause it to occur. The water treatment device 10 returns the response data to the home treatment machine 100, and the home treatment machine 100 relays this information back to the appropriate service personnel.

  [0066] The request sent from the service personnel can be structured such that the machine 100 essentially knows whether the request is for the home treatment machine 100 or the water treatment device 10. Alternatively, the request can be tagged. For example, the valves of the home treatment machine 100 may be numbered sequentially from the number 1 and the valves of the water treatment apparatus 10 may be numbered sequentially from the number 100 (of the home treatment machine 100). It is assumed that there are less than 100 valves). Here, it is essentially understood that a request to switch the number 111 valve is passed to the water treatment device 10. Alternatively, the valves of both the home treatment machine 100 and the water treatment apparatus 10 are sequentially numbered starting with number 1, for example, “A” is for the home treatment machine 100 and “B” is for the water treatment apparatus 10. The request can also be coded. Here, it is known that the ACPU 112 of the home treatment machine 100 holds the request to switch the valve AV4 and passes the request to switch the valve BV4 to the water treatment device 10.

Control through one user interface
[0067] In one embodiment, the control processor (ACPU 112) and user interface 122 of the home treatment machine 100 allow the patient to perform the entire treatment process and how to perform the treatment, such as instructions to operate the water treatment device 10. Step by step instructions on what to start and execute. In one embodiment, the user interface 122 is a tablet that implements a customized secure interface that only allows access to the home treatment machine 100. In one embodiment, the tablet 122 operates wirelessly. Here, the tablet 122 may first connect to the home treatment machine 100 to combine the tablet 122 and the home treatment machine 100 to perform a software (eg, firmware) upgrade of the tablet 122. In addition, the tablet 122 can be connected to the home treatment machine 100 to feed or charge the tablet 122. The connectivity between the tablet 122 and the home treatment machine 100 may be via a serial data connection, a universal serial bus (USB) connection, a parallel connection, or another suitable connection. It may be via a data transfer interface. When the tablet 122 is combined with the home treatment machine 100, the tablet 122 communicates wirelessly with the home treatment machine 100 (eg, using Bluetooth® or WiFi ™).

  [0068] Alternatively, the user interface 122 is shown and described in, for example, US Patent Application Publication No. 2009/0114582, for which the present application relies on all of its contents and is hereby incorporated by reference in its entirety. As such, it can be connected or coupled to the machine 100. Hereinafter, as shown in FIG. 3, a connection or connection configuration of the user interface 122 will be described.

  [0069] In one embodiment, a user can send data to and receive data from the machine 100 via the tablet 122. Data entered into the user interface 122 is securely transmitted to the home treatment machine 100 and processed by the ACPU 112, which forwards commands to control the machine 100 or to be processed by the water treatment device 10, Thereby, by extension, a part of the operation of the water treatment apparatus 10 is controlled. In one embodiment, treatment data is not stored on the tablet 122. Not storing treatment data on the tablet 122 is advantageous because sensitive or important data is not lost if the tablet 122 is disconnected or lost.

  [0070] Since the user interface 122 of the home treatment machine 100 is also used to input and display data relating to the water treatment device 10, the water treatment device 10 can be used in several ways, such as a membrane switch and an on / off switch. There is no need for more than a simple display, which may be equipped with an electromechanical button, and in one embodiment it is not. This simple display may be a small liquid crystal display (LCD) or light emitting diode (LED) display that displays one or several lines of text. The electromechanical button enables emergency control of the water treatment device 10 when the tablet 122 is lost or when communication between the home treatment machine 100 and the water treatment device 10 is lost. Alternatively or in addition, the electromechanical button allows the water treatment device 10 to be installed or serviced without the home treatment machine 100. The electromechanical button may also allow the service person to enter the service mode directly from the small keypad, for example by pressing and holding a hidden button for a certain number of seconds.

  [0071] In one embodiment, a user can power and power off the home treatment machine 100 and / or the water treatment device 10 from a common user interface 122. The user can transmit a command to the water treatment apparatus 10 from the common user interface 122. The command may request, for example, that the water treatment device 10 issue an estimated value of the time until it becomes necessary to replace the consumable components of the water treatment device 10. For example, the water treatment device 10 can include a carbon filter, a deposit removal cartridge, a mitigation filter, a reverse osmosis (RO) membrane, or a metal catalyst filter, each of which requires replacement after a period of use. As in the past, the command from the tablet 122 may be specific to the water treatment apparatus 10, and there may be no option other than the ACPU 112 transferring the command to the water treatment apparatus 10. Or the code which ACPU112 recognizes can also be provided in a command, and based on this, ACPU112 can also transfer this command to the water treatment apparatus 10 with sufficient responsiveness.

  [0072] One object of the present disclosure is to avoid having to see two different user interfaces when a user performs a home care procedure with the system 110. In addition to making the user interface 122 one common user interface, it is also contemplated to minimize the user interaction required by the water treatment device 10. For example, the water treatment apparatus 10 can be configured to remain in a power supply state indefinitely if the water treatment apparatus 10 is not adversely affected. Alternatively, the home treatment machine 100 and the water treatment apparatus 10 may be configured such that the water treatment apparatus 10 receives power whenever the home treatment machine 100 is powered. Similarly, many commands for the home treatment machine 100 can be carried over to the water treatment device 10 or can automatically have a secondary effect on the water treatment device 10. For example, a pause or stop input from the user interface 122 to the home treatment machine 100 similarly causes the home treatment machine 100 to automatically issue a pause or stop command to the water treatment device 10. Can do. In another example, if an alarm condition occurs while the home treatment machine 100 is receiving purified water from the water treatment device 10, the home treatment machine 100 sucks up water from the water treatment device 10. Can be stopped.

  [0073] The operating parameters of the home treatment machine 100 may also define the operating parameters of the water treatment device 10. For example, in the hemodialysis area, the flow rate of dialysate or dialysate input to the home treatment machine 100 as an operating parameter is the amount of purified water used by the water treatment device 10 to generate dialysate or dialysate. The flow rate commanded to be generated can be defined. This configuration of the preceding / following motion parameters can be implemented in a number of different ways. In one method, the ACPU 112 of the home treatment machine 100 calculates or finds the operation parameters of the water treatment device 10 via a lookup table based on the corresponding operation parameters of the home treatment machine 100. For example, the ACPU 112 can store setting the flow rate of purified water to 1.2 times the flow rate of the dialysate. During execution, the ACPU 112 calculates and adjusts the flow rate of purified water while knowing the current actual flow rate or current commanded flow rate of the dialysate of the home treatment machine 100. In one embodiment, the ACPU 112 can adjust the flow rate of purified water if it determines that the patient needs a bolus of fresh solution. One suitable method for providing a patient with a bolus of fresh solution is based on the application filed on Nov. 9, 2007, which this application relies on all of its contents and is hereby incorporated by reference in its entirety. U.S. Patent Application Publication No. 2009/0124963 entitled "Balanced Flow Dialysis Machine".

  [0074] In the second method, the control processor of the water treatment device 10 is based on a corresponding operating parameter of the home treatment machine 100 transmitted from the home treatment machine 100 to the water treatment device 10 via a lookup table. To calculate or discover the operating parameters of the water treatment device 10. For example, the control processor of the water treatment device 10 can store that the flow rate of purified water is set to 1.2 times the flow rate of the dialysate. The ACPU 112 periodically sends the current dialysate flow rate to the water treatment device 10, which knows the current actual flow rate or currently commanded flow rate of the dialysate of the home treatment machine 100. Calculate and adjust the flow rate of purified water while running.

  [0075] In the third method, the control processor of the water treatment device 10 deviates from the prescription, similar to the home treatment machine 100. In the following, the process by which the home therapy machine 100 receives one or more machine operating prescriptions from a physician or clinician remotely via the server 118 and system hub 120 described above will be described. When a machine operating prescription is installed on the ACPU 112 of the home treatment machine 100, the prescription is accompanied by a set of instructions or a secondary prescription set that is transferred from the ACPU 112 to the control processor of the water treatment device 10. Thereafter, when the prescription of the home treatment machine 100 is recalled by the user for treatment by the home treatment machine 100, the corresponding set of instructions or secondary prescription is recalled for use with the water treatment device 10. In the third method, data update between the home treatment machine 100 and the water treatment apparatus 10 during treatment can be reduced or eliminated.

  [0076] The fourth method operates on a batch or volume basis. The home therapy machine 100 can include a dialysate holding tank. The ACPU 112 may be configured to produce dialysate when the tank volume drops to a certain level and stop dialysate production when the volume of dialysate in the tank rises to a certain level. Here, the water treatment device 10 responds to concerns about the dialysate flow rate to the dialyzer by supplying sufficient water to raise the low dialysate volume in the tank to the high dialysate volume in the tank. Bear. When the tank capacity is low, the ACPU 112 operates the water treatment device 10 and the home treatment machine 100 dialysate mixing pump to produce dialysate and fill the dialysate holding tank. The water treatment device 10 and the dialysate mixing pump remain in operation until the specified high tank capacity is reached. Maintaining various dialysate production rates of the water treatment device 10 and the dialysate mixing pump, when the water treatment device 10 and the dialysate mixing pump have low production rates and cannot meet demand, their dialysate production rates It is intended to be able to increase. When the ACPU 112 increases or decreases the dialysate production rate, it adjusts both the water treatment device 10 and the dialysate mixing pump accordingly.

  [0077] The dialysate flow / purified water flow and / or volume control has been used to describe the leading / following operating parameter configuration, which can be applied to the pressure, temperature and / or water present in the water treatment device 10. Alternatively, configurations for use with other parameters, such as parameters relating to purity levels, are also explicitly contemplated.

  [0078] Referring now to FIG. 2, the exemplary dialysis machine 100a includes a water purification unit 10a, a dialysate preparation unit 224, a dialysate delivery unit 230, and a sterilization unit 226. In one embodiment, the controller 232 includes a plurality of controllers, each including a processor / memory. The controller 232 includes, for example, a master or supervisor processor that controls a plurality of delegate processors, each dedicated to various functions relating to the dialysis machine 100a. The controller 232 can also include a redundant processing unit, such as a safety processor that ensures that each other processor performs its function correctly.

  [0079] The controller 232 not only controls the heater 234, the pump 236, the valve 238, and the sensor 240, but also controls any one or more of the water purification unit 10a, the dialysate preparation unit 224, and the sterilization unit 226. Can be controlled. The home treatment machine and the water treatment device are shown separately in FIG. 1A, but can also be placed in the same housing as shown in FIG. In one embodiment, the same user interface 122 is used to control a controller 232 that can control any one or more of various units, such as a home treatment machine and a water treatment device, for example. Can do. The dialysis machine 100 a can be powered by a branch power supply 212 and / or an auxiliary power supply 214.

Data connection
[0080] Reference is now made to FIG. 3, which shows a subsystem 50 of the system 110 between the water treatment device 10 and the home treatment machine 100. FIG. For reference, the above simple display and electromechanical buttons of the water treatment device 10 are shown as display 20 and electromechanical buttons 22. Alternatively, the water treatment device 10 includes only the display 20 and includes only a rudimentary input device. The display of the water treatment device 10 can enhance the user interface 122. The control processing unit / memory of the water treatment apparatus 10 is shown as processing unit / memory 24. Also, as described above, the user interface 122 of the home treatment machine 100 is shown as being connected or connected to the home treatment machine 100. Alternatively, the user interface 122 is an unconnected tablet, as described herein above.

  [0081] As shown in FIG. 3, a data communication link 32 such as Ethernet or wired communication is provided between the processing unit / memory 24 of the water treatment device 10 and the ACPU 112 of the home treatment machine 100. Transmit data with. In one example, the water treatment device 10 uses the link 32 to provide status or status information for the home treatment machine 100, component life information, sensor level or reading, self-test results, warning and alarm information, and Send hardware and / or software version information. The water treatment device 10 can also indicate information relating to the water flow between the water treatment device 10 and the home treatment machine 100, such as flow rate information, water temperature information, and pipeline connection disinfection information.

  [0082] As further shown in FIG. 3, the data communication link 32 may also be used to transmit data between the ACPU 112 of the home treatment machine 100 and the treatment unit / memory 24 of the water treatment device 10. As described above or in addition, the home treatment machine 100 may include status change requests, commands (eg, execute, pause, or stop), status queries, flow rate change requests, software upgrades or downgrades, and / or For example, data relating to file transfer such as device prescription can be transmitted to the water treatment device 10.

  [0083] As described herein, the user interface 122 presents information about the water treatment device 10 to the user 12. For example, the user interface 122 can display information such as an alarm or warning notification, water treatment device performance information, troubleshooting help, task guidance, and / or operational requests to the user 12. For example, the user 12 reveals the identity of the device itself to the water treatment device 10 via the user interface 122, and the data connection means 32 between the machine 100 and the device 10 functions appropriately. And verifying compatibility, such as hardware version and software version compatibility between the device 10 and the machine 100. In that case, the device 10 itself can generate an audible beep or response and / or send back a confirmation message to the user interface 122, eg, “here”. Thereafter, the user 12 can perform an appropriate action via the user interface 122 or by performing some task indicated by the user interface 122. To do this, the user 12 need only interact with the common user interface 122. In this way, the user 12 can use physical data to turn on and off the hardware while ensuring that the water treatment device 10 is functioning properly and is in communication with the machine 100. Only minimal interaction with the water treatment device 10 is required, such as making connections and power connections, changing filters and / or performing manual measurements.

  [0084] In addition to the data connection means 32 between the home treatment machine 100 and the water treatment device 10, there is a water supply line 34 that runs from the water treatment device 10 to the home treatment machine 100. The water supply line 34 delivers a specified level of sterility, flow rate, pressure and / or temperature water to the home treatment machine 100. The water sent from the water treatment device 10 to the home therapy machine 100 is typically maintained between about 5 ° C and 35 ° C. In one embodiment, the conduit 34 may be used to return unused water product from the home treatment machine 100 to the water treatment device 10.

  [0085] In one embodiment, the treatment unit / memory 24 of the water treatment device 10 operates as a slave or delegate processor to the programmed ACPU 112 of the home treatment machine 100. The water treatment device 10 can notify the home treatment machine 100 of the status of the device such as an alarm status, and can send any other relevant data to the ACPU 112. The home therapy machine 100 stores the data, acts on the data, and determines whether to issue an alarm, for example. Accordingly, the home treatment machine 100 controls the behavior of the water treatment device 10.

  [0086] The water treatment device 10 may take any one of several different states, such as "installation", "system cleaning", "sleeping" or "treatment". In one embodiment, the home treatment machine 100 is responsible for requesting the water treatment device 10 to change state, for example, from “sleeping” to “treatment”. In the “sleeping” state, the water treatment apparatus 10 is maintained in the minimum power usage state. In the “treatment” state, the water treatment device 10 is at a fully functional power level. As mentioned above, the system and method of the present invention contemplates many ways to couple the water treatment device 10 to the home treatment machine 100 when there is a request for water from the home treatment machine 100. In each alternative, the water treatment device 10 supplies water suitable for treatment to the home treatment machine 100 in an appropriate amount or flow rate.

  [0087] The water treatment device 10 can transmit information to be displayed on the user interface 122 to facilitate the necessary user action. The water treatment device 10 can send the status information to the home treatment machine 100 asynchronously or in response to a status query. The water treatment apparatus 10 can also transmit an error packet to the home treatment machine 100 when there is an error or an alarm. The home therapy machine 100 can determine what action needs to be taken and whether the user 12 should be notified via the user interface 122. The user 12 can do this via the user interface 122 if necessary to provide any input to clear the alarm. The water treatment device 10 is responsible for notifying the home treatment machine 100 about the current state of the device. The water treatment device 10 also plays a role of notifying the home treatment machine 100 about any alarms or warnings.

  [0088] When water is required for treatment, the home treatment machine 100 of the above-described embodiment designates a desired water flow rate to the water treatment device 10. Next, the water treatment apparatus 10 supplies water at the desired flow rate. Alternatively, as described above, the water treatment device 10 calculates or retrieves the flow rate based on the treatment liquid flow rate transmitted from the home treatment machine 100. Alternatively, as described above, the water treatment device 10 determines its flow rate from its own device recipe. Furthermore, as described above, the water treatment device 10 and the home treatment machine 100 can also cooperate on a volumetric basis.

  [0089] Controlling both the water treatment device 10 and the home treatment machine 100 from the user interface 122 increases safety and minimizes the complexity of operating multiple devices at home. It should be understood that the burden of treatment on the patient is reduced. In addition, the functions of the water treatment device 10 and the home treatment machine 100 are rationalized by the master / delegate processor configuration.

Installation of water treatment equipment
[0090] The system 110 often contemplates that the water treatment device 10 and the home treatment machine 100 work together in many different ways through a common user interface 122. Referring now to FIG. 4, for example, process 400 is an exemplary process for installing or initializing water treatment device 10 using user interface 122 of home treatment machine 100. Upon starting the process 400 in the start block, the user 12 connects the water treatment device 10 to the home treatment machine 100 as shown in block 402, for example, establishing the data connection means 32 and the water line connection 34 described above. When the user interface 122 detects a data connection, the user interface 122 confirms to the user 12 whether or not he / she wants a guide regarding the installation of the water treatment device 10, as shown in block 404. If user 12 selects “No”, the process ends with an end block beside block 404. If the user 12 selects “Yes”, the user interface 122 prompts the user 12 to install the RO cartridge first and press “Confirm” on the user interface 122 as shown in block 406. .

  [0091] When the user 12 presses "confirm", the home treatment machine 100 queries the water treatment device 10 as to whether the RO cartridge has been detected and installed correctly, as shown in block 408. If the RO cartridge is not detected or is not installed correctly, the water treatment device 10 reports an error condition as indicated at block 410 and displays an error message on the user interface 122 as indicated at block 411. . If the RO cartridge is detected and correctly installed, the water treatment device 10 responds at the user interface 122 that the RO cartridge is present, as shown in block 412, and returns the cartridge information to the home treatment. Send to machine 100.

  [0092] Next, as shown in block 414, the user interface 122 displays to the user 12 "Please install the pre-processing cartridge and press" Confirm "". When the user 12 installs the cartridge and presses “confirm” on the user interface 122, the home therapy machine 100 queries the water treatment device 10 for the presence of the pretreatment cartridge, as shown at block 416. If the pretreatment cartridge is not present or there is an error, the water treatment device 10 responds with a pretreatment cartridge error, as shown at block 418. In this case, as shown in block 420, the user interface 122 displays a message to the user 12 indicating that the pretreatment cartridge is not properly installed. If a pretreatment cartridge is present, the water treatment device 10 responds that the pretreatment cartridge is present and sends cartridge information to the home treatment machine 100, as shown in block 422.

  [0093] Next, as shown in block 424, the user interface 122 prompts the user 12 to connect the water treatment device 10 that supplies water, turn on the water supply, and press "Confirm". Is displayed. When the user 12 presses “Confirm”, the home treatment machine 100 queries the water treatment device 10 as shown in block 426 whether the water supply is connected and / or whether the water supply pressure is acceptable.

  [0094] Next, as shown in block 428, the user interface 122 prompts the user 12 to "place the drain line in the drain and ensure that an air gap exists". If the user 12 confirms these steps, as shown in block 430, the user interface 122 will send a message to the user indicating that the water treatment device 10 will begin cleaning and that the cleaning may take several hours. 12 is displayed. The user interface 122 also displays a “clean” button. When the user 12 presses the “wash” button, the water treatment apparatus 10 starts washing, as shown in block 432. Therefore, it is not necessary to provide a separate “wash” button in the water treatment apparatus 10, but it may be provided for redundancy. In any case, as shown in block 434, the water treatment device 10 changes the device state to “cleaning” and notifies the home treatment machine 100 of this state change. The user interface 122, as shown in block 436, displays “Washing. Press“ Stop ”to pause the cleaning process” and displays a “Stop” or “Pause” button accordingly. . Also, as shown in block 438, the water treatment device 10 reports not only the system mode of the entire device, but also the status of the valves and pumps. When the cleaning is complete, as shown in block 440, the user interface 122 displays that the cleaning is complete. Also, as shown in block 442, the status change is also reported to the home treatment machine 100. Thereafter, the process 400 ends as shown in the end block.

  [0095] Although the above steps of process 400 include individual functions performed by water treatment apparatus 10, it should be understood that the display of instructions and user input is performed on user interface 122. Therefore, the user 12 can concentrate on only the user interface 122 and install the water treatment apparatus 10 to execute the treatment of the home treatment machine 100.

Water generation
FIG. 5 is a diagram illustrating an exemplary process 500 for generating water with the water treatment device 10 using the user interface 122 of the home treatment machine 100. Upon starting the process 500 at the start block, as shown at block 502, the home therapy machine 100 becomes active, or “wakes up,” at a specified flow rate (or dialysate in the dialysate holding tank). Commands the water treatment device 10 to produce water (until the specified capacity is reached). In one embodiment, the water treatment device 10 performs the necessary functions before producing water. When active, i.e., activated, the home therapy machine 100 performs start-up activities such as self-examination, cleaning and safety checks. At block 506, when the water treatment apparatus 10 completes the required activity, it “wakes up” and is ready to produce water. The home therapy machine 100 continuously inquires about the status of the water treatment device 10 and displays this status on the user interface 122 as shown in block 508. As shown in block 510, if the home treatment machine 100 is in use when the water treatment device 10 has completed startup and is ready to produce purified water, as shown in block 512. The water treatment device 10 waits for the home treatment machine 100 to draw water. When the home treatment machine 100 is ready, the home treatment machine 100 begins to draw water, as shown at block 514. As shown in block 516, the user interface 122 displays to the user 12 that the home treatment machine 100 is drawing water from the water treatment device 10.

  [0097] The user interface 122 may provide an option for the user 12 to change the water preparation flow rate of the water treatment device 10, or to pause or stop water production. Alternatively, as described above, the home treatment machine 100 can instruct the water treatment apparatus 10 to change the flow rate based on the instruction stored in the ACPU 112. In one embodiment, the water treatment device 10 is configured to change the recovery rate based on demand. In the RO unit of the water treatment apparatus 10, defective water is generated. Bad water can be collected and returned to the RO unit to reduce the water that is actually rejected and discharged, but doing so causes fouling by sending the recycled bad water to the RO unit. There is a possibility that the service life of the RO unit may be shortened. However, if the home treatment machine 100 does not use all of the available flow of purified water produced by the water treatment device 10, the bad water flow from the RO unit is mixed with excess purified water. Thus, a solution that is functionally equivalent to tap water and does not cause excessive fouling of the RO unit can be produced. In this way, the water treatment device 10 can adjust the amount of bad RO water to be recycled based on the availability of unused purified water that can be mixed with the bad stream before re-entering the RO unit. it can.

  [0098] When the home treatment machine 100 finishes drawing water, the home treatment machine 100 commands the water treatment device 10 to sleep, as indicated at block 518. Even in the dormant state, the water treatment device 10 continues to communicate with the home treatment machine 100 and waits until an activation command is received again. Further, in the dormant state, the water treatment apparatus 10 may periodically clean the flow path for each set stagnation period in order to maintain the performance of the apparatus without the activation command. The water treatment device 10 changes the device state to a dormant state, as shown in block 520, and sends the state to the home treatment machine 100 for display to the user 12. Thereafter, the process 500 ends as indicated in the end block.

Start of home treatment machine and water treatment equipment
FIG. 6 is a diagram illustrating an exemplary process 600 for starting the home treatment machine 100 and the water treatment device 10 using the user interface 122 of the home treatment machine 100. Upon starting the process 600 at the start block, the user interface 122 causes the user 12 to perform a start-up check on the water treatment device 10 as shown at block 602. For example, the user interface 122 may check the UV intensity, RO failure rate, and total organic carbon (TOC) level, each associated with the water treatment device 10, and request the user 12 to perform its self-test. Other self-tests associated with the water treatment device 10 include, for example, whether the remaining pretreatment cartridge life is sufficient.

  [00100] A self-inspection of the water treatment apparatus 10 includes a chlorine / chloramine inspection. For example, the ACPU 112 may determine that a chlorine / chloramine test should be performed. The user interface 122 can prompt the user to collect a water sample for testing from the water treatment device 10 by pressing a button on the user interface 122 as needed. A chlorine / chloramine test is performed, as shown at block 603, and the user interface 122 displays options for the results of the chlorine / chloramine test (eg, pass or fail) to the user, as shown at block 606, and The user can be prompted to respond. Depending on the results of the chlorine / chloramine test, the process 600 may complete other self-tests on the device 10, return to self-test on the home treatment machine 100, or proceed to another task on the water treatment device 10. be able to.

  [00101] Thus, the process 600 can alternate between step 602 and step 603, as indicated by the double arrow between step 602 and step 603. For example, if the water treatment device 10 fails the chlorine / chloramine test, the home treatment machine 100 needs a pre-treatment swap or needs to re-examine the sample to confirm the failure. It is possible to notify the water treatment apparatus 10 of a signal. The water treatment device 10 changes the system state to “cartridge swap” and notifies the ACPU 112 of this state change. The user interface 122 displays to the user 12 that the water treatment apparatus 10 needs a pretreatment cartridge swap. The user interface 122 then causes the user 12 to perform a step of swapping the pretreatment cartridge. Any errors in the water treatment device 10 are displayed to the user 12 via the user interface 122. Alternatively, as shown at block 606, the user interface 122 can prompt the user for a response. When the pretreatment cartridge swap step is complete, the water treatment device 10 changes the device status and sends the status to the home therapy machine 100 for display to the user 12.

  [00102] If all self-tests associated with the water treatment device 10 yield an error-free positive result, the user interface 122 may perform a self-test of the home treatment machine 100, as shown in block 604. Migrate to Alternatively, the ACPU 112 can alternately perform a self-inspection of the home treatment machine 100 and a self-inspection of the water treatment device 10. In other words, as described above, the self-inspection of the water treatment apparatus 10 is performed after the self-inspection of all the home treatment machines 100 is first performed, or vice versa. It may not be desirable to perform a self-test of the home treatment machine 100 after the test is first performed. Self-tests may be performed alternately or simultaneously. Thus, the process 600 can alternate between step 602, step 603, and step 604 as indicated by the double arrows between step 602 and step 603 and between step 602 and step 604. As shown in block 606, a self-test of the home treatment machine 100 or the water treatment device 10 can display the results to the user 12 on the user interface 122 at any time or prompt the user 12 to respond. . By performing the inspection alternately in this way, it is possible to improve efficiency and save time while allowing the user 12 to focus on one user interface 122.

  [00103] Process 600 ends as shown in the end block, but may end later from any of steps 602, 603, or 604, depending on the results of the self-test and the sequence of alternating self-tests. .

Implementation of pretreatment cartridge / membrane swap
[00104] FIG. 7 is a diagram illustrating an exemplary process 700 for performing a pretreatment cartridge swap of the water treatment device 10 using the user interface 122 of the home treatment machine 100. As shown in FIG. When the process 700 starts at the start block, as shown at block 702, the water treatment device 10 checks whether the pretreatment cartridge is completely degraded. If the pretreatment cartridge is not fully degraded but needs to be replaced soon, the water treatment device 10 alerts the home treatment machine 100 via the data connection means 32, as shown in block 704. Is transmitted. The user interface 122 indicates that the pretreatment cartridge should be replaced soon, as shown in block 706, and in one embodiment, an option regarding whether the user 12 should replace the pretreatment cartridge now or later, and A selection button is presented to the user 12. If the user chooses to replace the pretreatment cartridge later via the user interface 122, the process 700 ends as shown in the end block. If the user chooses to replace the pretreatment cartridge now via the user interface 122, the process 700 proceeds to step 712 described below.

  [00105] If the pretreatment cartridge is completely degraded and the water treatment device 10 cannot produce water unless it is immediately replaced, the water treatment device 10 may connect to the data connection as shown at block 708. An alarm is transmitted to the home treatment machine 100 via means 32 to cause the user interface 122 to indicate to the user 12 that the pretreatment cartridge should be replaced immediately, as shown at block 710.

  [00106] If the user 12 chooses to replace the pretreatment cartridge now in the user interface 122 (if the pretreatment cartridge is not needed), or if the pretreatment cartridge must be replaced immediately, the user interface 122, in one embodiment, causes the user 12 to perform the process of replacing the pretreatment cartridge, as shown at block 712. User task instructions are displayed on the user interface 122. When the pretreatment cartridge swap is complete, the water treatment device 10 changes the device state, as shown at block 714, and this change is displayed to the user 12 via the user interface 122, as shown at block 716. The In various embodiments, the process 700 may alternatively or additionally be used to perform an RO membrane swap. Thereafter, the process 700 ends as indicated in the end block.

Setting and using supplements and treatment prescriptions
[00107] The pharmaceutical products and drugs are transported or delivered to the patient's home for use by the home therapy machine 100 during the procedure. Normally, only therapeutic products or drugs approved by the physician's prescription can be transported to the patient's home. In the United States, such prescriptions usually last for a year and patients may be able to use multiple prescriptions at any given time to dynamically manage their condition. The system hub 120 stores one or more prescriptions for each patient. Each home therapy machine 100 uses supplies and settings according to this prescription. If there is a change in the patient's prescription, or if a prescription is added, the patient clinician can use the web portal 150 to update the settings of the home treatment machine 100 to change the prescription or to add. When the setting of the home treatment machine 100 is updated, the system hub 120 transmits the updated setting to the home treatment machine 100 through the connectivity service as described above. For example, in one embodiment, the home treatment machine 100 communicates with the system hub 120 only when the connectivity agent 114 is turned on.

  [00108] Referring now to FIG. 8, a process 800 illustrates an exemplary process for transporting inventory and programming a prescription for the home treatment machine 100 based on a physician's prescription for a particular patient. That is, a physician associated with the clinics 152a-152n accesses the system hub 120 via the web portal 150 to deliver the patient's treatment prescription (used for both supplies and machine operations) to the clinician. You can also Once the process 800 begins at the start block, the clinician uses the web portal 150 to retrieve the electronic prescription prescribed by the physician, as shown at block 802. At the web portal 150, the clinician fills the prescription, including a dialyzer, blood circuit set, acid, bicarbonate, needle, etc., and possibly also supplies for the water treatment device 10, to meet the home treatment machine 100. Select any other supplies needed to carry out in As shown in block 804, the selected dialyzer and other supplies are transported to the patient's home.

  [00109] Simultaneously or at different times, the clinician can remotely access the system hub 120 via the web portal 150 to program the prescription for the home treatment machine 100, as shown in block 806. . The system hub 120, in one embodiment, holds the treatment prescription until the connectivity agent 114 of the home treatment machine 100 is turned on, as shown in blocks 820-824.

  [00110] The clinician sets various treatment parameters used to program the home therapy machine 100 prescription, such as blood flow, dialysate flow, UF volume, and heparin flow flush, as shown in block 808. To do. In one embodiment, the settings specified by the clinician include settings for operating the water treatment device 10 or may affect the parameters of the water treatment device 10 as described above. It is not necessary to set the parameters of the water treatment device 10 separately. Alternatively, the clinician can separately set various treatment parameters used to program the prescription of the water treatment device 10, as indicated at block 810.

  [00111] The clinician also specifies various setting tolerances, as shown in block 812. That is, the patient is allowed to choose a value for a particular parameter within a certain range of values under a specified treatment prescription. In this way, the patient has a certain amount of control over the treatment to be performed. For example, the temperature of the dialysate can be set within an acceptable range based on patient preference and comfort. The clinician further specifies whether the patient can modify the settings at all, as shown in block 814. If the patient is allowed to modify the parameter setting, the variability of the setting is within an acceptable range, and the patient selects a value within the range specified by the clinician at block 812. The clinician then submits this setting to the system hub 120 as shown at block 816.

  [00112] The system hub 120 then sends the treatment prescription to the connectivity server 118, as shown at block 818. As shown in block 820, when the connectivity agent 114 in the home treatment machine 100 is next turned on or becomes operational, the home treatment machine 100, as shown in block 822, Check connectivity server 118 for treatment prescription. If the treatment prescription for the home treatment machine 100 is in the connectivity server 118, the connectivity server 118 sends the treatment prescription to the home treatment machine 100 as shown in block 824. Machine 100 prompts the patient to accept the treatment prescription. In one embodiment, the patient must accept the treatment prescription and continue to use the home treatment machine 100 as shown at block 826.

  [00113] In one embodiment, the treatment prescription downloaded from the connectivity server 118 may be a new or updated prescription to replace a previous treatment prescription already in the machine 100. Before starting the treatment, for example after the previous day's sterilization, the ACPU 112 of the home treatment machine 100 has the connectivity service via the agent 114 publish an updated treatment prescription for that particular home treatment machine 100 Check if. To do this, in one embodiment, the home treatment machine 100 and the system hub 120 compare the prescription version number via the connectivity service and the home treatment machine 100 was last updated. It is determined whether it has. If not the last updated prescription, the last version of the prescription is delivered to the treatment machine 100. The machine 100 does not execute the old treatment prescription if a new treatment prescription is downloaded from the connection server 118 and exists in the machine 100. However, the new treatment prescription does not overwrite the old treatment prescription until the patient accepts the treatment prescription, as shown at block 826. In this way, the patient confirms that he knows that his procedure has changed. When a new treatment prescription is accepted, the new treatment prescription is written to the memory of the treatment machine 100. In an alternative embodiment, the machine 100 can store multiple treatment prescriptions in memory so that old treatment prescriptions are retained in memory even when new treatment prescriptions are downloaded. Machine 100 may be capable of storing various types or categories of treatment prescriptions. Each different type of therapeutic regimen may provide a different treatment, for example, removing a small amount, a medium amount, or a large amount of ultrafiltrate for dialysis. Machine 100 may be able to store one treatment prescription for each category.

  [00114] The ACPU 112 receives the setting, separates the setting of the home treatment machine 100 from the setting of the water treatment device 10, and sets the setting of the water treatment device 10 via the data connection means 32, as shown in block 827. It transmits to the water treatment apparatus 10. The setting can be flagged as a setting for a home treatment machine or a setting for the water treatment device 10. Alternatively, the ACPU 112 can recognize that the characteristics being set are unique to the water treatment apparatus 10 and pass the settings to the water treatment apparatus 10. When the patient next attempts to perform the procedure, the connectivity agent 114 is turned off, as shown in block 828. As indicated at block 830, the home therapy machine 100 performs the procedure using the therapy prescription specified at blocks 808 and / or 810. The home therapy machine 100 writes the treatment data resulting from the treatment to a log file, as indicated by block 832. Again, the log file documents the relevant home treatment machine 100 data being treated and the relevant water treatment device 10 data. In one embodiment, the water treatment device 10 sends the device's own log file to the home treatment machine 100. The home treatment machine 100 loads the data from the water treatment device 10 into the log file of the home treatment machine 100. Next, when the connectivity agent 114 is turned on, the combined log file stored in the home treatment machine 100 is transmitted to the connectivity server 118.

  [00115] As shown in block 834, the connectivity agent 114 is turned on. In one embodiment, home therapy machine 100 initiates a connection to a connectivity service. In an alternative embodiment, the connectivity service may initiate a connection to the home treatment machine 100. At block 836, the log file is uploaded to the connectivity server 118. Thereafter, the process 800 ends as shown in the end block.

  [00116] In one embodiment, the machine 100 may perform a post-treatment procedure, such as a sterilization procedure that cleans the machine and disposables used in the procedure in preparation for the next procedure. In one embodiment, the system 110 may turn on the connectivity agent at block 834 after the procedure but while the post-treatment sterilization is taking place. The writing of treatment data in block 832 can also occur during sterilization. Alternatively, the home therapy machine 100 waits to write at block 832 or turn on the connectivity agent at block 834 until sterilization is complete and the machine 100 is in idle mode.

  [00117] In the illustrated embodiment, the system 110 does not perform real-time monitoring of the treatment because the connectivity agent 114 is turned off before the treatment and will not be turned on again until after the treatment. Events that occur during the procedure, such as alarms and warnings, are not immediately reported to the system hub 120. Such information is included in a log file transmitted to the system hub 120 after the treatment. In an alternative embodiment, the connectivity agent 114 can remain on during the procedure and report information about the home therapy machine 100 and the procedure in real time.

Firmware upgrade
[00118] The software that the ACPU 112 executes on the home treatment machine 100 and / or the software executed on the processing unit / memory 24 of the water treatment device 10, sometimes referred to herein as firmware, is upgraded. Sometimes it is necessary. Home medical device system 110 provides an efficient and reliable way to upgrade firmware, including product development team 128 and service personnel 132a-132n (FIG. 1A).

  [00119] FIG. 9 is a diagram illustrating an exemplary process 900 for upgrading the firmware of the home treatment machine 100. As shown in FIG. Upon starting the process 900 at the start block, the product development team 128 develops a firmware upgrade for the home treatment machine or water treatment device 10, as shown at block 902. At block 904, product development team 128 uploads the firmware upgrade to system hub 120. The service portal 130 then allows the service personnel supervisor or decision maker 134 to view and approve the upgrade. Upon approval of the upgrade, the supervisor 134 uploads the upgrade from the system hub 120 to the connectivity server 118, as shown at block 906. In the embodiment shown in FIG. 1A, the supervisor 134 is a separate person from the service personnel 132a-132n responsible for the inspection and maintenance of the home treatment machine 100 and the water treatment device 10 and the relationship building with the patient. The service personnel supervisor 134 has the authority to finalize whether to send an upgrade to the connectivity server 118, as well as any machine 100 and / or water treatment device, if not all machines 100 or device 10. 10 can specify whether to receive the upgrade, or the upgrade can be rejected or returned to product development team 128 for improvement. Once the upgrade is allowed to reach connectivity server 118, service personnel 132a-132n, or designated persons therein, may view the firmware upgrade via service portal 130, as shown at block 908. it can. In one embodiment, product development team 128 uploads the firmware upgrade directly to connectivity server 118 without going through system hub 120.

  [00120] As described above in connection with FIG. 1A, service personnel 132a-132n manage daily relationships with patients. Service personnel 132a-132n are familiar with the patient's schedule and are in the best position to determine when the patient should receive a firmware upgrade. For example, the service personnel 132a-132n know the maintenance and operation schedules of the home treatment machine 100 and the corresponding water treatment device 10 that they normally check. If the patient machine 100 and / or the water treatment device 10 is scheduled to receive the parts needed for a firmware upgrade, the service personnel 132a-132n will wait for the new parts to be introduced. The firmware of the patient's home treatment machine 100 and / or the water treatment device 10 (e.g., may require new parts thereof) may be upgraded.

  [00121] Each service personnel 132a-132n selects which of the designated home treatment machine 100 and / or water treatment device 10 should receive the firmware upgrade, as shown in block 910. As shown in block 912, when the connectivity agents 114 of the selected home therapy machine 100 are next turned on, the connectivity server 118 that was waiting for those agents to turn on is blocked. As shown at 914, the upgrade is sent to the selected home treatment machine 100 and / or water treatment device 10.

  [00122] In one embodiment, the selected home therapy machine 100 and / or water treatment device 10 is based on the settings stored in the ACPU 112 and / or the processor / memory 24, as shown in block 916. You can decide whether to accept the upgrade. If the selected home treatment machine 100 and / or water treatment device 10 chooses not to upgrade, the process 900 ends as shown in block 916 and the end block. If any of the selected home treatment machine 100 and / or water treatment device 10 accepts the upgrade, the upgrade is performed for the corresponding patient via user interface 122 as shown in block 918. Check if you want to install. If the patient does not choose to upgrade the selected home treatment machine 100 and / or water treatment device 10 via the user interface 122, the process 900 is as shown in block 920 and the end block. finish. If the patient chooses to upgrade the selected home treatment machine 100 and / or water treatment device 10 via the user interface 122, one of them, as shown in block 922, is shown. Alternatively, multiple upgrades are performed and the home treatment machine 100 notifies the patient that the software has been upgraded via the user interface 122. In some countries, legislation must obtain patient approval before upgrading patient firmware. In one embodiment, the system 110 may require that only the home therapy machine 100 in the country that requires patient approval prompt the patient to accept the firmware upgrade at blocks 918 and 920.

  [00123] The home therapy machine 100 may retain the ability to return to previous software versions of either or both of the machine 100 or the device 10. For example, if the firmware upgrade is corrupted, or if the firmware of the home treatment machine 100 or the water treatment device 10 is corrupted, in one embodiment, the home treatment machine 100 reverts to the previous non-corrupted software version. be able to. Alternatively, the home therapy machine 100 may not be able to return to the previous software version. Here, when the software is damaged or damaged, new software is installed, or the home treatment machine 100 or the water treatment device 10 is replaced with the new home treatment machine 100 or the water treatment device 10. Replace with.

  [00124] The connectivity service at server 118 documents all events related to firmware upgrades, such as which patients received the upgrade and which service personnel 132a-132n were involved in the upgrade. The connectivity server 118 stores the serial number, tracking number, and software version, and the various steps of the upgrade process are documented and the current software version of each machine 100 and device 10 of the system 110 at any given moment. It is easy to get. At the end block of FIG. 9, process 900 ends.

  [00125] As described above, any software update of the water treatment device 10 can also be transmitted to the water treatment device 10 via the home treatment machine 100. The home treatment machine 100 may receive a combined software upgrade that includes software upgrades of both the home treatment machine 100 and the water treatment device 10. Alternatively, upgrades can be delivered separately. Next, the ACPU 112 analyzes the software content of the home treatment machine 100 and separates it from the software content of the water treatment device 10. In particular, the ACPU 112 can recognize which software content is for the home treatment machine 100 and which software content is for the water treatment device 10. For example, the software content essentially looks like content specific to either the home treatment machine 100 or the water treatment device 10 or content specific to either the home treatment machine 100 or the water treatment device 10. Can be included. Alternatively, the software content can be flagged for the home treatment machine 100 or the water treatment device 10. Next, the home treatment machine 100 transmits the software content for the water treatment device 10 to the water treatment device 10 via the data connection means 32.

  [00126] Firmware upgrades may also be provided in the manner described above for other household components of system 110, such as tablet 122, blood pressure monitor 104, and / or scale 106, for example.

Clinician dashboard with rule evaluation
[00127] The clinician can view a list of the clinician's patients and each patient's file that shows how the patient's treatment was performed. The treatment file is obtained from the log file of the home treatment machine 100, such as the actual flow rate achieved, ultrafiltrate removal, the actual ultrafiltration rate achieved, blood pressure during treatment, weight, and the like. In addition, the log file may include treatment data of the water treatment device 10 as described above. The stored treatment data of the water treatment device 10 includes, for example, the total volume of purified water delivered, the average water temperature, the average water pressure, the number of delivery requests from the machine 100, warning and alarm information, chlorine / chloramine levels, and / or Examples include component usage or exchange information.

  [00128] The clinician may categorize patient lists into, for example, hemodialysis (eg, subdivided into short daily, night, every other day, every other day, etc.), peritoneal dialysis (eg, continuous circulation peritoneal dialysis (CCPD), tidal, etc.) Can be categorized by a number of categories, such as the type of treatment the patient has received (such as subdivided), the responsible physician, or the notices described below. The clinician can also see a picture of the patient and an overview of the week, month or other period.

  [00129] The web portal 150 provides a clinician dashboard with notifications about events that occurred during the procedure. In one embodiment, these notifications include color-coded flags such that each color corresponds to a different notification state. The clinician can select which events generate a red or yellow flag that appears on the dashboard. In one embodiment, the flag setting is determined for each clinic and not for each patient. Therefore, if you choose to be notified about a particular event, it applies to all patients in the clinic or all patients being viewed by the clinician. For example, the clinician may set a rule that a yellow flag will appear on the dashboard if the duration of the treatment is less than 4 hours. This rule will apply to all patients in the clinic or to all patients seen by the clinician. The dashboard shows all patients who have been treated for less than 4 hours, for example by a yellow flag. These flags may also relate to the water treatment device 10, for example the chlorine / chloramines that were posted or inspected when the disposable life of the water treatment device 10 was less than 10 hours Or you can post a red flag when you reach a certain level.

  [00130] FIG. 10A is a diagram illustrating an exemplary dashboard screen 1000 of a clinic shown on the clinician's display 192. FIG. Dashboard screen 1000 is the screen that the clinician sees first when logging into web portal 150 in one embodiment. The dashboard screen 1000 shows an overview of patients being treated at the clinic and how the treatment by the home treatment machine 100 and the water treatment apparatus 10 has been performed.

  [00131] As shown in column 1002, patients are listed by name. Dashboard 1000 can allow a clinician to apply a filter as drop-down menu 1010 indicates. For example, in the illustrated embodiment, the clinician can filter dashboard information by patient type (not shown), physician in drop-down menu 1012, or patient status (not shown). The clinician may also filter the dashboard information to show only treatments for which there was no communication using the checkbox 1014, or to show only treatments for which a flag was generated using the checkbox 1016. it can. These filters allow clinicians to focus their attention on specific desired information.

  [00132] Various icons 1004, 1006 and 1008 indicate information regarding the treatment performed by the patient on a particular day. Icons 1004, 1006, and 1008 can indicate different types of events. For example, icon 1004 can be used to indicate that the procedure performed by home therapy machine 100 and water treatment device 10 was successful. The icon 1006 can be used to notify the clinician about events that are not critical and do not need to be addressed immediately, but that need to be closely monitored. For example, icon 1008 can be used to notify the clinician of events that need to be addressed immediately.

  [00133] The user may access the description using link 1018. When the user selects link 1018, a pop-up window or new screen 1050 appears. FIG. 10B is an exemplary illustration screen 1050 that illustrates various icons that may appear on the dashboard screen 1000 that are displayed on the clinician's display 192. The icon 1004 indicates that the result of the treatment performed by the home treatment machine 100 and the water treatment apparatus 10 is “OK”. An icon 1008 indicates a flag with a high priority. The icon 1006 indicates a normal priority flag. Icon 1010 indicates that there was no communication with the home treatment machine 100 associated with the patient for a particular treatment.

  [00134] In one embodiment, the dashboard also displays information collected by the water treatment device 10 in a log file of the water treatment device 10. FIG. 11A shows an exemplary treatment summary screen 1100 shown on the clinician's display 192 that is part of the clinician's dashboard or accessible via a link from the dashboard. is there. The treatment summary screen 1100 provides details about the specific treatment performed on the patient by the home treatment machine 100 and the water treatment device 10 collected in the log file as described above. FIG. 11A shows information about the treatment performed by the home treatment machine 100 and the water treatment apparatus 10 on July 31, 2010 as shown in the chart 1102. From the treatment summary screen 1100, the clinician can see an explanation of flag symbols in the chart 1101. Also, the clinician can see the date, start time and total dialysis time in chart 1102, can see the prescription device program in chart 1104, and in chart 1106 the home treatment machine 100 and / or An overall treatment summary log showing the exact time of various treatment events in the water treatment device 10 can be viewed in tabular form. The treatment summary screen 1100 also shows information collected from the water treatment apparatus 10. For example, item 1107 of chart 1106 indicates to the clinician that water treatment device 10 has indicated a cold water warning at time 20:41:13. Any warning or event documented in the log file and displayed on the clinician dashboard can also be communicated to the user 12 via the user interface 122 when that warning or event occurs during treatment. .

  [00135] The screen 1100 displayed on the clinician's display 192 continues in FIG. 11B. As shown in FIG. 11B, the clinician can see details of fluid management in chart 1108, can see information regarding treatment dose in chart 1110, and sees heparin details in chart 1112. In chart 1114, data on extended use of the dialyzer can be viewed, in chart 1116 blood pressure can be examined, and in chart 1118 pulse details can be viewed.
