FIELD OF THE DISCLOSURE [0002] This disclosure relates generally to renal therapy systems, and more particularly to systems and methods for controlling water treatment devices exclusively via dialysis machines.

[0003] A person's renal system can fail due to causes such as disease and injury. There are several physiological perturbations in renal failure of any cause. Kidney failure makes it impossible to balance water and minerals and to excrete the daily metabolic load. During renal failure, harmful end products of nitrogen metabolism (urine, creatinine, uric acid, etc.) can accumulate in blood and tissues.

[0004] Renal disorders and renal insufficiency are treated with dialysis. Dialysis removes waste, toxins and excess water from the body that would otherwise be removed by the normally functioning kidneys in a healthy body. Dialysis treatment as a replacement for kidney function is important to many people because it saves lives. People with impaired kidneys may not be able to survive without at least a replacement for the filtering function of their kidneys.

[0005] Hemodialysis and peritoneal dialysis are two types of dialysis therapies commonly used to treat loss of kidney function. Hemodialysis treatment uses the patient's blood to remove waste, toxins and excess water from the patient. A patient is connected to a hemodialysis machine, which draws the patient's blood. A catheter or needle is inserted into the patient's circulatory system to connect the blood flow to the hemodialysis machine. Blood and dialysate pass through the dialyzer of a hemodialysis machine. A dialyzer can include a semi-permeable membrane that separates blood and dialysate. As blood passes through the dialyzers of a hemodialysis machine, the dialyzers remove waste, toxins and excess water from the patient's blood. Specifically, toxins are osmotically transferred from the blood through the membrane into the dialysate. A hemodialysis machine returns this blood to the patient. A large amount of dialysate, for example about 120 liters, is used to dialyze the blood in one hemodialysis treatment. The spent dialysate is then discarded. Hemodialysis treatments last several hours and are generally performed at a treatment center three or four times a week.

[0006] Peritoneal dialysis uses a dialysis solution or "dialysate" that is infused into the patient's peritoneal cavity through a catheter implanted in the peritoneal cavity. The dialysate contacts the patient's peritoneal membrane in the peritoneal cavity. Waste, toxins and excess water move from the patient's bloodstream through the peritoneal membrane and into the dialysate. 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, removing waste, toxins and excess water from the patient. This cycle repeats.

[0007] There are various types of peritoneal dialysis therapy, including continuous ambulatory peritoneal dialysis (CAPD), automated peritoneal dialysis, and continuous flow peritoneal dialysis. CAPD is a manual dialysis procedure in which the patient connects an implanted catheter to a drain to allow spent dialysate to drain from the peritoneal cavity. The patient then connects the catheter to a bag of fresh dialysate and manually infuses fresh dialysate through the catheter into the patient's peritoneal cavity. The patient disconnects the catheter from the bag of fresh dialysate, allowing the dialysate to dwell in the peritoneal cavity and transport 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, patients perform several drain/fill/dwell cycles during the day, eg, about four times a day. One treatment cycle usually takes about one hour. Manual peritoneal dialysis performed by the patient requires considerable time and effort. This inconvenient procedure leaves considerable room for improvement and therapeutic enhancement to improve the patient's quality of life.

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

[0010] An APD device delivers fresh dialysate from a dialysate source through a catheter into the patient's peritoneal cavity, where the dialysate passes through the peritoneal cavity so that waste, toxins and excess water can be transported from the patient's bloodstream to the dialysate. allow you to stay inside. The APD machine then pumps spent dialysate through the catheter and out of the peritoneal cavity to the drain. APD machines are usually computer controlled so that dialysis treatment occurs automatically when the patient is connected to the dialysis machine, eg, while the patient is asleep. That is, the APD system automatically and continuously pumps fluid into the peritoneal cavity, dwells, aspirates fluid from the peritoneal cavity, and repeats the procedure.

[0011] Similar to manual processes, several drain/fill/dwell cycles occur during APD. A "last fill" is typically used at the end of APD, whereby fluid remains in the patient's peritoneal cavity when the patient is disconnected from the dialysis machine for the day. APD saves the patient from having to manually perform drain, dwell and fill steps.

[0012] Frequent dialysis is a part of life for patients with kidney disease. Most peritoneal dialysis patients undergo dialysis once a day. Hemodialysis patients typically require dialysis several times a week. There is an increasing demand for home dialysis methods to enable patients to lead as normal a life as possible. Peritoneal dialysis is usually done at home. Blood treatment therapies such as hemodialysis and hemofiltration are often performed in centers and clinics.

[0013] Performing dialysis at home, whether hemodialysis or peritoneal dialysis, adds difficulty and complexity to the patient. Dialysis is typically performed using a dialysis machine and a fluid supply. The fluid supply may be prepared in one or more prepared solution bags or may be prepared on-line via water treatment equipment and concentrated additives. In the case of water treatment equipment, the dialysis machine and the water treatment equipment are operated simultaneously in order to successfully implement the therapy. Operating two machines or devices can be difficult, especially for elderly or immobile patients who may not be able to quickly observe and/or operate both devices. There is Viewing information on two devices and/or entering information on two devices can be cumbersome. Both dialysis machines and water treatment devices generate data that it may be desirable to store for analysis. This data must be accurate, timely, and provide sufficient detail.

[0014] Therefore, a home-use water treatment device that integrates a water treatment device with a hemodialysis machine so that control of both machines or devices can be centralized and data can be easily exchanged with both machines or devices. A dialysis system is needed.

[0015] The system and method of the present disclosure integrate the operation of the dialysis machine and the water treatment device so that the user essentially operates the water treatment device from the dialysis machine. That is, the user interface with the water treatment device is the user interface that controls the dialysis machine. Although the water treatment device may have its own small user interface, the primary control of the water treatment device is through the dialysis machine. It also transfers data from both machines to a central repository maintained by the care provider, provides reporting of treatment data to clinicians for both dialysis machines and water treatment equipment, integrates with payment and ordering systems, and supplies consumables. It also contemplates tracking the use of , delivering consumables as needed, and servicing and maintaining machines on the system's network. To this end, in one embodiment, the dialysis machine is in data stream communication with the water treatment device via Ethernet or other wired communication. A dialysis machine is in communication with a system or network. In this way, data from the water treatment device can be sent to the network or system via the dialysis machine. The system or network can similarly send operating 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 replacement machines. Including, but not limited to, home therapy machines such as (CRRT) machines. Although renal therapy is one focus of this disclosure, the present disclosure contemplates the integration of any home fluid delivery therapy, such as home drug delivery therapy or nutritional therapy. In various embodiments, home remedies use medical fluids that can be generated online or at the point of use from a source of purified water, such as ultrapure water, as that term is understood in the art. any type of therapy. For example, PD is usually performed using bagged dialysate, but instead generates an online PD solution originating from a source of ultrapure or sterile water, optionally with dextrose It is also contemplated to add PD concentrates, such as concentrates of lysate and glucose.

[0017] It is also contemplated that the home remedy is nutritional therapy using purified water from the water treatment system as a basis for preparing a nutritional solution that is delivered to the patient. In either situation, all controls of the water treatment device are used to control the home therapy machine, which in one embodiment is a blood processing home therapy machine, a PD home therapy machine, or a home nutritional therapy machine. through the same user interface as

[0018] It is also contemplated that the home medical device system will transfer the treatment prescription to the home therapy machine. A doctor's prescription is made for a kidney or other type of home treatment. A clinician can remotely select supplies to be sent to a patient's home based on a doctor's prescription, including supplies for both home therapy machines and water treatment equipment. Also, the clinician can 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 the therapy machine. The operating parameters of the water treatment device are transferred by the home therapy machine to the water treatment device 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 may also be performed via the home therapy machine. Once the upgraded firmware is generated, it is sent to the home therapy machine. This new firmware will be installed on the home therapy machine if it is intended for the home therapy machine. If this new firmware is intended for the water treatment device, the home therapy machine will transfer the new firmware to the water treatment device and install it on the water treatment device. Certain jurisdictions may require users to accept software upgrades, whether for home therapy machines or water treatment devices. In either case, the user intends for the user interface of the home therapy machine, whether for the home therapy machine or the water treatment device, to be able to accept this new firmware.

[0020] It is also contemplated to provide operational prescriptions and new firmware with tags that specify which of the home therapy machine and the water treatment device receives the operational instructions or firmware. Alternatively, the instructions and firmware may appear essentially as content specific to either the home therapy machine or the water treatment device, or have content specific to either the home therapy machine or the water treatment device. may be In the latter case, the home therapy machine can determine whether the home therapy machine itself will accept or forward the command or firmware upgrade to the water treatment device based on the unique characteristics it detects. can. No additional tags are needed here.

[0025] Yet another advantage of the present disclosure is to provide an improved system and method for transmitting firmware upgrades to multiple machines or devices that are collaborating to provide home therapy.

[0026] Yet another advantage of the present disclosure is that data is exchanged in a reliable and secure manner between a server and a plurality of machines or devices collaborating to provide home therapy. It is a guarantee.

[0027] Yet another advantage of the present disclosure is that data is delivered from a server to multiple home treatment machines or devices while they are in operation. It is to prevent.

[0028] Furthermore, it is an advantage of the present disclosure to allow a user to control features of procedures involving multiple machines or devices using a single user interface.

If the home therapy machine 100 is a home hemodialysis machine, one suitable machine is the following: August 2008, from which this application relies in its entirety and which is hereby incorporated by reference in its entirety. US Patent Application Publication No. 2009/0101549, filed May 27, entitled "Modular Assembly For A Hemodialysis System."

[0046] Although one home therapy machine 100 is shown in communication with the connectivity server 118, the system 110 oversees the operation of multiple home therapy machines 100 of the same or different types. . For example, M hemodialysis machines 100, N hemodialysis machines 100, O hemodiafiltration machines 100, P peritoneal dialysis machines 100, Q hemodialysis machines 100 connected to server 118 and operating with system 110 There may be a home drug delivery machine 100 and R home nutritional therapy machines 100 . The numbers of M to R may be the same or different, and may be zero, one, or multiple.

[0047] In the illustrated embodiment, the home therapy machine 100 receives purified water from the water treatment device 10 at its front end. One suitable water treatment system 10 is described in "Water Purification System And Method," filed Apr. 25, 2011, the contents of which this application relies in its entirety and which is hereby incorporated by reference in its entirety. US Patent Application Publication No. 2011/0197971 entitled In one embodiment, the water treatment system 10 outputs ultrapure water as that term is understood in the art. The ultrapure water can be passed through one or more filters, such as an ultrafiltration membrane or a dialyzer that produces water of or near injectable or pharmaceutical quality. This injectable quality water is then mixed with one or more dry, liquid or slurry concentrates to form (i) an injectable replacement solution for HF or HDF, (ii) a PD solution. , (iii) drugs for infusion, or (iv) nutrient solutions for infusion.

[0048] System 110 assumes that home therapy machine 100 operates with other devices besides water treatment device 10, such as blood pressure monitor 104, scales such as wireless scale 106, and wireless tablet user interface 122. is shown. Home therapy machine 100 connects to server 118 wirelessly via modem 102 in one embodiment. Each of these components, including the water treatment system 10, are generally located within the patient's home, as indicated by the dashed lines in FIG. 1A. Any one, any plurality, or all of components 10 , 104 , 106 and 122 may communicate with home therapy machine 100 either wired or wirelessly. Wireless communication is via Bluetooth®, WiFi®, Zigbee®, Z-Wave®, wireless universal serial bus (USB), infrared, or other suitable wireless communication technology. It can be carried out. Alternatively, any one, any plurality, or all of components 10, 104, 106 and 122 may communicate with home therapy machine 100 by wire.

[0049] In one embodiment, the water treatment device 10 connects to the home therapy machine 100 via an Ethernet cable. In one embodiment, the water treatment device 10 is powered by its own power source. The home therapy machine 100 can request water from the water treatment device 10 as needed. The water treatment system 10 is sized and configured to supply any amount of water required by the machine 100 either online or batchwise.

[0050] The connectivity server 118 communicates with the majority of the home medical device system 110 via the home medical device system hub 120 . The system hub 120 allows data and information regarding each of the home therapy machines 100 and water treatment devices 10 on the system 110 to be transferred between the machines 100 and other clients connected to the server 118 via the connectivity server 118 . can come and go. In the illustrated embodiment, system hub 120 is connected to service portal 130, enterprise resource planning system 140, web portal 150, business intelligence portal 160, HIPAA compliant database 124, product development team 128, and electronic medical record databases 126a-126n. be.

[0051] Electronic medical record (EMR) databases 126a-126n store electronic information about patients. The system hub 120 can transmit data collected from machine 100 log files, described in detail below, to hospital or clinic databases 126a-126n to combine or supplement the patient's medical records. Because databases 126a-126n can store patient-specific treatment and prescription data, access to these databases can be highly restricted. The enterprise resource planning system 140 captures and compiles data generated through patient and clinician website access, such as complaints, payment information, and lifecycle management information. Web portal 150 allows patients and clinics 152 a - 152 n treating patients to access publicly available web sites of system 110 . Business intelligence portal 160 collects data from system hub 120 and feeds data to marketing 162 , research and development 164 and quality/post-market pharmacovigilance 166 .

These instructions may be configured to be executed by a processor that, when executing a series of computer instructions, performs or facilitates the performance of all or part of the disclosed methods and procedures.

Data transfer for water treatment equipment
[0057] In one embodiment, home therapy machine 100 performs a home treatment, such as home hemodialysis, on a patient at the patient's home, and then reports the results of the treatment to the patient's health and well-being administrator. clinicians, physicians and nurses who are Treatment results include data supplied from the water treatment device 10 to the home therapy machine 100 . The water treatment device 10 data may include, for example, the total volume of water delivered, the quality of the water delivered (e.g. chlorine content), e.g. The number of times water was delivered to the therapy machine 100 (this data may be monitored by the device 10 or by the machine 100), the average flow rate of water delivered, any alarms or Warnings, and/or number of cycles performed during time or procedure, and the like.

[0058] The home therapy machine 100 writes log files using, for example, the Linux® operating system. The log file again documents the relevant home therapy machine 100 data and the relevant water treatment device 10 data during treatment. The log files may include any one or more of Extensible Markup Language (XML), Comma Separated Values (CSV), or text files. The log file is located in the file server box of the home therapy machine 100 software. Data not sent to machine 100 is intended to be stored at water treatment system 10 . Alternatively, such data may be obtained via an Ethernet data connection to the water treatment system 10, or downloaded via other data connections or storage media. For example, service personnel may access additional data via a laptop connected to the water treatment system 10 via an Ethernet connection. Alternatively, the home therapy machine 100 may function as a data transfer connection between the water treatment device 10 and an authorized system client to retrieve additional data remotely from the water treatment device 10 as described herein. can.

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

[0060] The connectivity agent 114 allows the home therapy machine 100 to connect to the connectivity server 118 and transfer data to and from the connectivity server 118, such as water treatment device 10 data. can. Connectivity services operating through agent 114 and server 118 ensure that connections with machine 100 are secure, ensure that data passes correctly through machine 100's firewall, and prevent data or system crashes. is happening and the connectivity server 118 is communicating with the correct home therapy machine 100 to ensure that it is.

[0061] In one embodiment, the home therapy machine 100 can only connect to the connectivity server 118 when the connectivity agent 114 is turned on. Connectivity agent 114 is turned off during treatment and post-treatment disinfection when machine 100 and water treatment device 10 are functioning. This prevents the home therapy machine 100 from communicating with any entity to send or receive data during treatment and disinfection, or while the machine 100 is powered on or in operation. ACPU 112 turns on connectivity agent 114 when home therapy machine 100 is idle, such as after treatment and post-sterilization are complete. In one embodiment, connectivity agent 114 is turned off only during treatment (including pretreatment). Connectivity agent 114 then retrieves log files from home therapy machine 100 and transfers data, such as water treatment device 10 data, to connectivity server 118 using connectivity services. The connectivity service routes data packets to the proper destination, but in one embodiment does not modify, access or encrypt that data.

[0062] In system 110 of FIG. The connectivity server 118 allows service personnel 132a-132n and/or clinicians to access various assets on the network, such as the appropriate home therapy machine 100 and 3G, 4G or 5G modem 102, as well as the serial number of the machine or modem. It is possible to track and extract information related to those assets such as 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 to access authorized home therapy machines 100 and their associated water treatments. It can also be provided in the device 10.

[0063] In one embodiment, the connectivity agent 114a (not shown) can be installed not only on the home therapy machine 100, but also on the water treatment device 10. FIG. If the home therapy machine 100 cannot 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 communicates with the system hub via the connectivity agent 114a. 120 can communicate directly. Alternatively, the connectivity agent 114a may be installed on a separate device or unit (not shown) that can be selectively connected to the water treatment device 10 to allow the home therapy machine 100 to communicate with the system hub 120, for example. It may also be possible to convert the water treatment device 10 to communicate directly with the system hub 120 again in the event of a loss.

Inspection of water treatment equipment
[0064] In one embodiment, the home therapy machine 100 allows service personnel to access both the home therapy machine 100 and the water treatment device 10 locally and/or remotely to diagnose and troubleshoot both. It can be operated in service mode. For example, a patient may be able to call a service person or technician if there is a problem with the water treatment system 10, or if a component thereof, such as a chemical pack, has been used. The patient and/or service personnel can then remotely verify the water treatment system 10 via the home therapy machine 100 and the service technician the settings and functionality of the water treatment system 10 for various components of the water treatment system 10. You can put it into service mode. In one embodiment, system 110 suspends treatment while a service technician is working on machine 100 to improve safety. For example, service personnel may be allowed to log on to device 10 via machine 100 while treatment is suspended. Alternatively, machine 100 must be idled or powered off to allow service personnel to access machine 100 and/or equipment 10 . Alternatively, machine 100 may simply need to be disconnected from the patient to allow service personnel access to machine 100 and/or device 10 .

[0065] Once accessed, the service technician can remotely inspect log files stored on the home therapy machine 100 to determine the cause of an error occurring on the water treatment device 10. and can be taken out. The service personnel may also use the water treatment system 10 to determine if relevant sensors, such as pressure sensors, are operating properly and/or if valves or pumps of the water treatment system 10 are operating properly. , may be able to switch valves and activate pumps. The service person does this by sending commands to the home therapy machine 100 . The home therapy machine 100 recognizes that this command is intended for the water treatment system 10 and passes this command to the processing section/memory of the water treatment system 10, thereby initiating the appropriate operation of the water treatment system 10. give rise to The water treatment device 10 transmits the response data back to the home therapy machine 100, which relays this information back to the appropriate service personnel.

[0066] Requests sent by service personnel can be structured such that the machine 100 inherently knows whether the request is for the home therapy machine 100 or the water treatment device 10 . Alternatively, requests can be tagged. For example, the valves of the home treatment machine 100 may be numbered sequentially starting with 1, and the valves of the water treatment device 10 may be numbered sequentially starting with 100 (the (assuming less than 100 valves). Here, it is inherently known to pass the request to the water treatment system 10 to switch the number 111 valve. Alternatively, the valves of both the home treatment machine 100 and the water treatment device 10 are numbered sequentially starting from 1, for example, "A" for the home treatment machine 100 and "B" for the water treatment device 10. You can also code the request, such as Here, the ACPU 112 of the home therapy machine 100 knows to hold the request to switch valve AV4 and pass the request to the water treatment device 10 to switch valve BV4.

Control via one user interface
[0067] In one embodiment, the control processor (ACPU 112) and user interface 122 of the home therapy machine 100 guide the patient through the entire treatment process and how the treatment is performed, including instructions to operate the water treatment device 10. Step by step instructions on what to start and run. In one embodiment, user interface 122 is a tablet that implements a customized secure interface that only allows access to home therapy machine 100 . In one embodiment, tablet 122 operates wirelessly. Here, the tablet 122 can be first connected to the home therapy machine 100 to combine the tablet 122 and the home therapy machine 100 and perform a software (eg, firmware) upgrade of the tablet 122 . The tablet 122 can also be connected to the home therapy machine 100 to power or charge the tablet 122 . Connectivity between the tablet 122 and the home therapy 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 through a data transfer interface. When tablet 122 is combined with home therapy machine 100, tablet 122 communicates wirelessly with home therapy machine 100 (eg, using Bluetooth® or WiFi™).

[0068] Alternatively, the user interface 122 is shown and described, for example, in US Patent Application Publication No. 2009/0114582, to which this application relies in its entirety and is incorporated herein by reference in its entirety. It can also be connected or coupled to the machine 100 as such. The connection or coupling configuration of the user interface 122 will now be described as shown in FIG.

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

[0070] The user interface 122 of the home therapy machine 100 is also used to enter and display data about the water treatment device 10, so the water treatment device 10 has several switches such as a membrane switch and an on/off switch. It requires nothing more than a simple display, which may include electromechanical buttons, and in one embodiment does not. This simple display may be a small liquid crystal display (LCD) or light emitting diode (LED) display, displaying one or several lines of text. The electro-mechanical button allows emergency control of the water treatment device 10 in the event that the tablet 122 is lost or communication between the home therapy machine 100 and the water treatment device 10 is lost. Alternatively or additionally, the electro-mechanical button allows installation or servicing of the water treatment device 10 without the home therapy machine 100 being present. Electromechanical buttons may also allow service personnel to enter a service mode directly from a miniature 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 down the home therapy machine 100 and/or the water treatment device 10 from the common user interface 122. A user can send commands to the water treatment device 10 from the common user interface 122 . The command may, for example, request that the water treatment system 10 provide an estimate of the time until a consumable component of the water treatment system 10 will need to be replaced. For example, the water treatment system 10 can include carbon filters, sediment removal cartridges, mitigation filters, reverse osmosis (RO) membranes, or metal catalyst filters, each requiring replacement after a period of use. As is conventional, commands from tablet 122 can be specific to water treatment system 10 such that ACPU 112 has no choice but to forward the command to water treatment system 10 . Alternatively, the command may be provided with a code recognized by the ACPU 112, based on which the ACPU 112 may transfer the command to the water treatment device 10 with good responsiveness.

[0072] One purpose of the present disclosure is to eliminate the need for a user to see two different user interfaces when performing home therapy procedures with the system 110. FIG. In addition to making user interface 122 one common user interface, it is also contemplated that water treatment system 10 requires as little user interaction as possible. For example, the water treatment device 10 can be configured to remain powered indefinitely if the water treatment device 10 is not adversely affected. Alternatively, the home therapy machine 100 and the water treatment device 10 can be configured such that the water treatment device 10 receives power whenever the home therapy machine 100 is powered. Similarly, many commands to the home therapy machine 100 can carry over to the water treatment system 10 or automatically have secondary effects on the water treatment system 10 . For example, a pause or stop input from the user interface 122 to the home therapy machine 100 likewise causes the home therapy machine 100 to automatically issue a pause or stop command to the water treatment device 10. can be done. In another example, if an alarm condition occurs while the home therapy machine 100 is receiving purified water from the water treatment device 10, the home therapy machine 100 will stop siphoning water from the water treatment device 10. can stop.

[0073] The operating parameters of the home therapy machine 100 may also define the operating parameters of the water treatment device 10. For example, in the area of hemodialysis, the dialysate or dialysate flow rate entered into the home therapy machine 100 as an operating parameter determines the amount of purified water that the water treatment device 10 uses to produce the dialysate or dialysate. A flow rate that is commanded to produce can be defined. Configuring this lead/launch operating parameter can be implemented in a number of different ways. In one method, the ACPU 112 of the home therapy machine 100 calculates or finds the operating parameters of the water treatment device 10 via a lookup table based on the corresponding operating parameters of the home therapy machine 100 . For example, the ACPU 112 can remember to set the purified water flow rate to 1.2 times the dialysate flow rate. On the fly, the ACPU 112 calculates and adjusts the flow rate of purified water knowing the current actual or commanded flow rate of dialysate for the home therapy 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 bolus of fresh solution to a patient is described in the following filed on Nov. 9, 2007, which this application relies on in its entirety and which is hereby incorporated by reference in its entirety. U.S. Patent Application Publication No. 2009/0124963 entitled Balanced Flow Dialysis Machine.

[0074] In a second method, the control processor of the water treatment device 10, based on the corresponding operating parameters of the home therapy machine 100 sent to the water treatment device 10 from the home therapy machine 100, via a look-up table. to calculate or discover the operating parameters of the water treatment system 10 . For example, the control processor of the water treatment device 10 can remember to set the purified water flow rate to 1.2 times the dialysate flow rate. The ACPU 112 periodically sends the current dialysate flow rate to the water treatment device 10 so that the water treatment device 10 knows the current actual or commanded flow rate of dialysate for the home therapy machine 100 . Calculate and adjust the purified water flow rate on the fly.

[0075] In a third method, the control processor of the water treatment device 10, like the home therapy machine 100, falls out of the prescription. The following describes the process by which home therapy machine 100 receives one or more machine operating prescriptions from a physician or clinician remotely via server 118 and system hub 120 described above. When a machine operating prescription is installed in the ACPU 112 of the home therapy machine 100 , the prescription is accompanied by a set of instructions or secondary prescriptions that are transferred from the ACPU 112 to the control processor of the water treatment device 10 . Thereafter, when a home therapy machine 100 prescription is invoked by a user for treatment by the home therapy machine 100 , a corresponding set of instructions or secondary prescriptions are invoked for use with the water treatment device 10 . This third method can reduce or eliminate data updates between the home therapy machine 100 and the water treatment device 10 during treatment.

[0076] A fourth method operates on a batch or volume basis. Home therapy machine 100 may include a dialysate holding tank. The ACPU 112 can be configured to produce dialysate when the volume of the tank drops to a certain level and to stop dialysate production when the volume of dialysate in the tank rises to a certain level. Here, the water treatment system 10 works to provide enough water to raise the low dialysate volume in the tank to the high dialysate volume in the tank for concerns about dialysate flow to the dialyzer. bear. When the tank volume reaches a low level, the ACPU 112 activates the dialysate mixing pumps of the water treatment system 10 and the home therapy machine 100 to produce dialysate and attempt to fill the dialysate holding tank. The water treatment system 10 and dialysate mixing pump remain operational until the specified high tank volume is reached. Maintaining different dialysate production rates for the water treatment unit 10 and the dialysate mixing pump, and if the water treatment unit 10 and the dialysate mixing pump are too low to meet demand, is intended to be able to increase When the ACPU 112 increases or decreases the dialysate production rate, it adjusts both the water treatment system 10 and the dialysate mixing pump accordingly.

[0077] While the dialysate flow rate/purified water flow rate and/or volume control has been used to describe the lead/track operating parameter configuration, this configuration can be used to control the pressure, temperature and/or the water present in the water treatment device 10. Or configurations for use with other parameters, such as those relating to purity level, are also expressly contemplated.

[0078] Referring now to FIG. In one embodiment, controller 232 includes multiple controllers, each including a processing unit/memory. Controller 232 includes, for example, a master or supervisor processor that controls multiple delegate processors, each dedicated to a different function for dialysis machine 100a. Controller 232 may also include redundant processing units, such as safety processors that ensure that each of the other processors performs their functions correctly.

[0079] Controller 232 controls heater 234, pump 236, valve 238 and sensor 240, as well as any one or more of water purification unit 10a, dialysate preparation unit 224 and disinfection unit 226. can be controlled. Although the home therapy machine and water treatment device are shown separately in FIG. 1A, they 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 a variety of units, such as home therapy machines and water treatment devices. can be done. The dialysis machine 100a may be powered by a branch power supply 212 and/or an auxiliary power supply 214. FIG.

data connection
[0080]Referring now to FIG. 3, FIG. For reference, the above-described simple display and electromechanical buttons of 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 has only rudimentary input devices. A display on the water treatment device 10 can enhance the user interface 122 . The control processor/memory of water treatment system 10 is shown as processor/memory 24 . Also, as mentioned above, the user interface 122 of the home therapy machine 100 is shown as coupled or connected to the home therapy machine 100 . Alternatively, user interface 122 is an untethered tablet, as described herein above.

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

[0082] As further shown in FIG. As or in addition to the above, the home therapy machine 100 may send state change requests, commands (e.g., run, pause, or stop), status queries, flow rate change requests, software upgrades or downgrades, and/or Data relating to file transfers, such as, for example, device prescriptions, can be sent 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. FIG. For example, user interface 122 may display information to user 12 such as alarm or alert notifications, water treatment device performance information, troubleshooting help, task guidance and/or action requests. For example, the user 12 may, via the user interface 122, reveal to the water treatment device 10 the identity of the device itself so that the data connection means 32 between the machine 100 and the device 10 are functioning properly. and require verification of compatibility, such as compatibility of hardware and software versions between device 10 and machine 100 . In that case, the device 10 itself may generate an audible beep or response and/or send a confirmation message back to the user interface 122, eg, "I am here." User 12 can then take appropriate action via user interface 122 or by performing any task indicated by user interface 122 . To do this, users 12 need only interact with a common user interface 122 . In this way, the user 12 has physical data to power on and off hard while ensuring that the water treatment system 10 is functioning properly and is in communication with the machine 100 . Minimal interaction with the water treatment system 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 therapy machine 100 and the water treatment device 10, there is a water supply line 34 running from the water treatment device 10 to the home therapy machine 100. Water supply line 34 delivers water at a specified level of sterility, flow rate, pressure and/or temperature to home therapy machine 100 . Water delivered 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, line 34 may also be used to return unused water product from home therapy machine 100 to water treatment device 10 .

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

[0086] The water treatment device 10 can be in any one of several different states, such as "Installation", "System Cleaning", "Sleep" or "Treatment". The home therapy machine 100, in one embodiment, is responsible for requesting the water treatment device 10 to change state, eg, from "sleep" to "treatment." In the "sleep" state, the water treatment system 10 is maintained in a minimal power usage state. In the "treatment" state, the water treatment system 10 is at a fully functional power level. As noted above, the systems and methods of the present invention contemplate numerous ways of coupling the water treatment device 10 to the home therapy machine 100 when there is a demand for water from the home therapy machine 100 . In each alternative, the water treatment device 10 supplies water suitable for treatment to the home therapy machine 100 at an appropriate volume or flow rate.

[0087] The water treatment device 10 may transmit information to be displayed on the user interface 122 to prompt the required user action. The water treatment device 10 can send status information to the home therapy machine 100 either asynchronously or in response to a status query. The water treatment device 10 can also send an error packet to the home therapy machine 100 in the event of an error or alarm. Home therapy machine 100 can determine what action needs to be taken and whether to notify user 12 via user interface 122 . If user 12 needs to provide any input to clear the alarm, he can do so through user interface 122 . The water treatment device 10 is responsible for informing the home therapy machine 100 about the current state of the device. The water treatment device 10 is also responsible for notifying the home therapy machine 100 of any alarms or warnings.

[0088] When water is needed for therapy, the home therapy machine 100 of one embodiment described above specifies the desired water flow rate to the water treatment device 10 . Water treatment system 10 then 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 therapeutic liquid flow rate transmitted from the home therapy machine 100 . Alternatively, as described above, the water treatment system 10 determines its flow rate from its own system prescription. Additionally, as noted above, the water treatment device 10 and the home therapy machine 100 can also work together on a volumetric basis.

[0089] Using and controlling both the water treatment device 10 and the home therapy machine 100 from the user interface 122 increases safety, minimizes the complexity of operating multiple devices, and allows It should be appreciated that the burden of treatment for patients with Also, the functionality of the water treatment device 10 and home therapy machine 100 is streamlined through a master/delegate processor configuration.

Installation of water treatment equipment
[0090] System 110 often contemplates that common user interface 122 allows water treatment device 10 and home therapy machine 100 to work together in many different ways. 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 therapy machine 100 . Beginning the process 400 at a start block, the user 12 connects the water treatment device 10 to the home therapy machine 100 as shown at block 402 to establish, for example, the data connection means 32 and water line connections 34 described above. When the user interface 122 detects the data connection, it asks the user 12 if he or she wants guidance regarding the installation of the water treatment device 10, as shown in block 404. FIG. If the user 12 selects “no”, the process ends at the 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 therapy machine 100 queries the water treatment device 10 if an RO cartridge has been detected and installed correctly, as shown in block 408. If an RO cartridge is not detected or installed incorrectly, the water treatment system 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 an RO cartridge is detected and properly installed, the water treatment system 10 responds at the user interface 122 that an RO cartridge is present and sends the cartridge information to the home remedy, as shown in block 412. send to machine 100;

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

[0093] Next, as shown in block 424, the user interface 122 displays a message to the user 12 asking the user 12 to connect the water treatment device 10 to supply water, turn on the water supply, and press "confirm". display. If the user 12 presses "confirm", the home therapy machine 100 queries the water treatment device 10 if the water supply is connected and/or if the water supply pressure is acceptable, as shown in block 426.

[0094] Next, as shown in block 428, user interface 122 prompts user 12 to "place drain line in drain and ensure an air gap exists." Once the user 12 has confirmed these steps, the user interface 122 displays a message to the user informing them that the water treatment device 10 will begin cleaning and that cleaning may take several hours, as shown in block 430 . 12. User interface 122 also displays a "clean" button. Once the user 12 presses the "Wash" button, the water treatment system 10 begins washing, as indicated at block 432 . Therefore, there is no need to provide a separate "flush" button on the water treatment system 10, although one may be provided for redundancy. In either case, the water treatment device 10 changes the device state to “Clean” and notifies the home therapy machine 100 of this state change, as indicated at block 434 . The user interface 122 displays "Cleaning. Press 'Stop' to pause the cleaning process," and displays a 'Stop' or 'Pause' button accordingly, as shown in block 436. . The water treatment system 10 also reports the status of the valves and pumps, as well as the overall system mode of the system, as indicated at block 438 . Once cleaning is complete, user interface 122 indicates that cleaning is complete, as indicated at block 440 . State changes are also reported to the home therapy machine 100 as indicated by block 442 . Thereafter, process 400 ends as indicated by the end block.

[0095] While the above steps of the process 400 include individual functions performed by the water treatment system 10, it should be understood that the display of instructions and user inputs is on the user interface 122. FIG. Accordingly, user 12 can focus solely on user interface 122 to install water treatment device 10 and perform home therapy machine 100 treatments.

water generation
[0096] FIG. 5 illustrates an exemplary process 500 for producing water with the water treatment device 10 using the user interface 122 of the home therapy machine 100. As shown in FIG. Beginning the process 500 with a start block, the home therapy machine 100 is activated or “woke up” to run at a specified flow rate (or dialysate in the dialysate holding tank), as shown in block 502 . command the water treatment system 10 to produce water (until a specified volume is reached); In one embodiment, the water treatment device 10 performs necessary functions prior to producing water. Once active, or booted, the home therapy machine 100 performs start-up activities such as self-examination, cleaning and safety checks. At block 506, once the water treatment device 10 has completed the required activities, it is "wake-up" and ready to produce water. The home therapy machine 100 continuously queries the status of the water treatment device 10 and displays this status on the user interface 122, as indicated at block 508. FIG. When the water treatment device 10 has completed startup and is ready to produce purified water, as indicated at block 510, and the home therapy machine 100 is in use, as indicated at block 512, , the water treatment device 10 waits for the home therapy machine 100 to draw water. Once the home therapy machine 100 is ready, the home therapy machine 100 begins to draw water, as indicated at block 514 . User interface 122 displays to user 12 that home therapy machine 100 is drawing water from water treatment device 10 , as indicated at block 516 .

[0097] The user interface 122 may also provide options 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 therapy machine 100 can instruct the water treatment device 10 to change the flow rate based on instructions stored in the ACPU 112 . In one embodiment, water treatment system 10 is configured to vary the recovery rate based on demand. In the RO unit of the water treatment device 10, defective water is produced. Rejected water can be collected and returned to the RO unit to reduce the amount of water that is actually rejected and discharged, but doing so causes fouling by sending recycled rejected water to the RO unit. As such, the useful life of the RO unit may be shortened. However, if the home therapy machine 100 is not using all of the available flow of purified water produced by the water treatment system 10, the defective water flow from the RO unit is mixed with the excess purified water. Thus, a solution can be produced that is functionally equivalent to tap water and does not cause excessive fouling of RO units. In this way, the water treatment system 10 can adjust the amount of recycled defective RO water based on the availability of fresh purified water that can be mixed with the defective stream before re-entering the RO unit. can.

[0098] When the home therapy machine 100 has finished drawing water, the home therapy machine 100 commands the water treatment device 10 to go to sleep, as shown in block 518 . Even in the dormant state, the water treatment device 10 continues to communicate with the home therapy machine 100 and waits for another activation command. Also, in the dormant state, the water treatment device 10 may periodically clean the flow path at set stagnation periods to maintain the performance of the device, even in the absence of a wake-up command. The water treatment device 10 changes the device state to a dormant state and sends that state to the home therapy machine 100 for display to the user 12, as indicated at block 520. FIG. Thereafter, process 500 ends as indicated by the end block.

Start-up of home treatment machines and water treatment equipment
[0099] FIG. 6 illustrates an exemplary process 600 for starting up the home therapy machine 100 and the water treatment device 10 using the user interface 122 of the home therapy machine 100. As shown in FIG. Beginning the process 600 at a start block, the user interface 122 allows the user 12 to perform start-up tests on the water treatment system 10 as shown at block 602 . For example, the user interface 122 can each confirm the UV intensity, RO defect rate and total organic carbon (TOC) level associated with the water treatment system 10 and request the user 12 to perform a self-test thereof. Other self-tests associated with the water treatment system 10 include, for example, whether there is sufficient remaining pretreatment cartridge life.

[00100] Self-testing of the water treatment system 10 includes a chlorine/chloramine test. For example, ACPU 112 may determine that a chlorine/chloramine test should be performed. The user interface 122 may 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 desired. A chlorine/chloramine test is performed, as indicated at block 603, and user interface 122 displays to the user options for the chlorine/chloramine test results (e.g., pass or fail), as indicated at block 606; The user can be prompted for a response. Depending on the results of the chlorine/chloramine test, process 600 completes other self-tests on device 10, returns to home therapy machine 100 self-tests, or proceeds to another task on water treatment device 10. be able to.

[00101] Thus, process 600 may alternate between steps 602 and 603, as indicated by the double-headed arrow between steps 602 and 603. FIG. For example, if the water treatment device 10 fails the chlorine/chloramine test, the home therapy machine 100 may need to pre-treat a swap or retest the sample to confirm failure. The water treatment device 10 can be signaled that there is. The water treatment device 10 changes its system state to "cartridge swap" and communicates this state change to the ACPU 112 . User interface 122 displays to user 12 that water treatment system 10 requires a pretreatment cartridge swap. The user interface 122 then takes the user 12 through the steps of swapping the pretreatment cartridges. Any errors in water treatment system 10 are displayed to user 12 via user interface 122 . Alternatively, the user interface 122 may prompt the user for a response, as indicated at block 606 . Upon completion of the pretreatment cartridge swap step, the water treatment device 10 changes the device state and sends the state 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 positive, error-free results, the user interface 122 prompts the user to perform a self-test of the home therapy machine 100, as shown in block 604. transition to Alternatively, the ACPU 112 may alternate between self-testing the home therapy machine 100 and self-testing the water treatment device 10 . In other words, performing the water treatment device 10 self-test after first performing all home therapy machine 100 self-tests, or conversely, all water treatment device 10 self-tests, as described above. It may not be desirable to perform a self-test of the home therapy machine 100 after performing a test the first time. Self-tests may be performed alternately or simultaneously. Thus, process 600 may alternate between steps 602, 603 and 604, as indicated by the double-headed arrow between steps 602 and 603 and between steps 602 and 604. FIG. At any time, the home therapy machine 100 or water treatment device 10 self-test can display the results to the user 12 on the user interface 122 or prompt the user 12 for a response, as indicated at block 606 . . Staggering the tests in this manner can increase efficiency and save time while allowing user 12 to focus on one user interface 122 .

[00103] Process 600 ends as shown in the end block, but may end after either step 602, 603 or 604, depending on the results of the self-tests and the order of alternate performance of the self-tests. .

Performing a pretreatment cartridge/membrane swap
[00104] FIG. 7 illustrates an exemplary process 700 for performing a pretreatment cartridge swap of the water treatment device 10 using the user interface 122 of the home therapy machine 100. As shown in FIG. Beginning the process 700 at a start block, the water treatment system 10 checks to see if the pretreatment cartridge is fully degraded, as indicated at block 702 . If the pretreatment cartridge is not fully degraded but needs to be replaced soon, the water treatment device 10 alerts the home therapy machine 100 via the data connection means 32, as shown in block 704. to transmit. The user interface 122 displays that the pretreatment cartridge should be replaced soon, as shown in block 706, and in one embodiment provides the user 12 with options as to whether the pretreatment cartridge should be replaced now or later, and A select button is presented to the user 12 . If the user chooses to replace the pretreatment cartridge later via user interface 122, process 700 ends as indicated by the end block. If the user chooses to replace the pretreatment cartridge now via user interface 122, process 700 proceeds to step 712, described below.

[00105] If the pretreatment cartridge is completely degraded and the water treatment system 10 is unable to produce water without immediate replacement, the water treatment system 10 will reconnect to the data connection, as shown in block 708. An alert is transmitted to home therapy machine 100 via means 32 to cause user interface 122 to indicate to user 12 that the pretreatment cartridge should be replaced immediately, as shown in block 710 .

[00106] If the user 12 selects to replace the pretreatment cartridge now in the user interface 122 (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 go through the process of replacing the pretreatment cartridge, as indicated by block 712 . User task instructions are displayed on user interface 122 . Once the pretreatment cartridge swap is complete, the water treatment system 10 changes the system status, as indicated at block 714, and this change is displayed to the user 12 via the user interface 122, as indicated at block 716. be. In various embodiments, process 700 may alternatively or additionally be used to perform an RO membrane swap. Thereafter, process 700 ends as indicated by the end block.

Setting up and using supplies and treatment regimens
[00107] Pharmaceutical products and medications are transported or delivered to the patient's home for use by the home therapy machine 100 during treatment. Normally, only medical products or medications approved by a doctor's prescription can be shipped to a patient's home. In the United States, such prescriptions typically last for one year, and patients may have multiple prescriptions available 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's clinician can use the web portal 150 to update the settings on the home therapy machine 100 to change or add the prescription. to add. When the home therapy machine 100 settings are updated, the system hub 120 sends the updated settings to the home therapy machine 100 via the connectivity service as described above. For example, in one embodiment, home therapy machine 100 communicates with system hub 120 only when connectivity agent 114 is turned on.

[00108] Referring now to FIG. 8, process 800 illustrates an exemplary process for shipping inventory and programming the prescription for home therapy machine 100 based on a physician's prescription for a particular patient. That is, physicians associated with clinics 152a-152n access system hub 120 via web portal 150 to deliver their patient's treatment prescriptions (used for both supplies and machine operation) to clinicians. You can also Once the process 800 begins at a start block, the clinician uses the web portal 150 to retrieve an electronic prescription prescribed by the physician, as shown at block 802 . At the web portal 150, the clinician fills his prescription, which includes dialyzers, blood circuit sets, acids, bicarbonates, needles, etc., and possibly also supplies for the water treatment machine 10, and supplies the home therapy machine 100 with it. Select any other supplies required to perform the The selected dialyzer and other supplies are shipped to the patient's home, as indicated at block 804 .

[00109] At the same time, or at another time, the clinician may remotely access the system hub 120 via the web portal 150 to program the prescription of the home therapy machine 100, as indicated at block 806. . The system hub 120, in one embodiment, holds the therapy prescription until the connectivity agent 114 of the home therapy machine 100 is turned on, as shown in blocks 820-824.

[00110] The clinician sets various treatment parameters used to program the prescription of the home therapy machine 100, such as blood flow, dialysate flow, UF volume and heparin flow flush, as shown in block 808. do. In one embodiment, the settings specified by the clinician may include settings for operating the water treatment device 10 or may affect 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 may separately set various treatment parameters that are used to program the water treatment device 10 prescription, as indicated at block 810 .

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

[00112] The system hub 120 then transmits the treatment prescription to the connectivity server 118, as indicated in block 818. FIG. The next time the connectivity agent 114 on the home therapy machine 100 is turned on or enabled, as indicated at block 820, the home therapy machine 100 will, as indicated at block 822: Check connectivity server 118 for treatment prescriptions. If the therapy prescription for the home therapy machine 100 is on the connectivity server 118 , the connectivity server 118 transmits the therapy prescription to the home therapy machine 100 as indicated at block 824 . Machine 100 prompts the patient to accept the treatment prescription. In one embodiment, the patient must accept the treatment prescription to continue using the home therapy machine 100, as indicated 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 on the machine 100. Before starting treatment, for example after sterilization the previous day, the ACPU 112 of the home therapy machine 100 determines if the connectivity service via the agent 114 has published an updated therapy prescription for that particular home therapy machine 100. to see if To do this, in one embodiment, home therapy machine 100 and system hub 120, via connectivity services, compare prescription version numbers to determine which prescription home therapy machine 100 was last updated with. determines whether it has If not the last updated prescription, the last version of the prescription is delivered to the therapy machine 100 . Machine 100 will not execute an old treatment prescription if a new treatment prescription has been downloaded from connection server 118 and is resident on machine 100 . However, the new treatment prescription will not overwrite the old treatment prescription until the patient accepts the treatment prescription as indicated at block 826 . In this way, the patient ensures that he/she is aware of any changes in his/her treatment. Upon acceptance of a new treatment prescription, the new treatment prescription is written into the memory of therapy machine 100 . In an alternative embodiment, the machine 100 can store multiple treatment prescriptions in memory so that older treatment prescriptions are retained in memory even when new treatment prescriptions are downloaded. Machine 100 may also be capable of storing various types or categories of treatment prescriptions. Each different type of therapeutic regimen may provide a different treatment, such as removing small, medium, or large amounts of ultrafiltrate for dialysis. Machine 100 may also be able to store one treatment prescription for each category.

[00114] The ACPU 112 receives the settings, separates the home therapy machine 100 settings from the water treatment device 10 settings, and transfers the water treatment device 10 settings via the data connection means 32, as shown in block 827. Send to the water treatment device 10 . A setting can be flagged as being a setting for a home therapy machine or a setting for a water treatment device 10 . Alternatively, the ACPU 112 may recognize the features being set as being specific to the water treatment system 10 and pass those settings to the water treatment system 10 . The next time the patient is about to perform a treatment, connectivity agent 114 is turned off, as indicated at block 828 . As indicated at block 830 , home therapy machine 100 performs treatment using the treatment prescription specified at blocks 808 and/or 810 . The home therapy machine 100 writes treatment data resulting from the treatment to a log file, as indicated at block 832 . Again, the log file documents the relevant home therapy machine 100 data and the relevant water treatment device 10 data during treatment. In one embodiment, the water treatment device 10 sends its own log file to the home therapy machine 100 . The home therapy machine 100 loads data from the water treatment device 10 into the home therapy machine 100 log file. The next time the connectivity agent 114 is turned on, the combined log files stored on the home therapy machine 100 are sent 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 the connectivity service. In an alternate embodiment, the connectivity service may initiate a connection to the home therapy machine 100. At block 836 , the log file is uploaded to connectivity server 118 . Thereafter, process 800 ends as indicated by the end block.

[00116] In one embodiment, the machine 100 is capable of performing post-treatment procedures, such as a sterilization procedure to clean 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 treatment, but while post-treatment disinfection is occurring. Writing treatment data in block 832 may 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 disinfection is complete and the machine 100 is in idle mode.

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

Firmware upgrade
[00118] Sometimes referred to herein as firmware, the ACPU 112 upgrades software running on the home therapy machine 100 and/or software running on the processing unit/memory 24 of the water treatment device 10. 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 illustrates an exemplary process 900 for upgrading the firmware of the home therapy machine 100. As shown in FIG. Beginning the process 900 at a start block, the product development team 128 develops a firmware upgrade for the home therapy 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 . Service portal 130 then allows a service personnel supervisor or decision maker 134 to view and approve the upgrade. Upon approving the upgrade, supervisor 134 uploads the upgrade from system hub 120 to connectivity server 118 , as indicated at block 906 . In the embodiment shown in FIG. 1A, the supervisor 134 is separate from the service personnel 132a-132n who are responsible for servicing and maintaining the home therapy machine 100 and water treatment system 10 as well as building relationships with patients. The Service Personnel Supervisor 134 not only has the final authority to decide whether to send an upgrade to the connectivity server 118, but also any, if not all machines 100 or equipment 10, and/or water treatment equipment. 10 can also specify whether to receive the upgrade, reject the upgrade, or return it to the product development team 128 for improvement. Once the upgrade is allowed to reach the connectivity server 118, the service personnel 132a-132n, or designated persons therein, may view the firmware upgrade via the service portal 130, as indicated in block 908. can. In one embodiment, product development team 128 uploads firmware upgrades 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 day-to-day 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 the firmware upgrade. For example, service personnel 132a-132n know the maintenance and operation schedules for home therapy machines 100 and corresponding water treatment devices 10 that they routinely service. If the patient's machine 100 and/or water treatment device 10 is due to receive parts required for a firmware upgrade soon, service personnel 132a-132n wait for the new parts to be installed before , the firmware of the patient's home therapy machine 100 and/or the water treatment device 10 (which may require new parts thereof, for example).

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

[00122] In one embodiment, the selected home therapy machine 100 and/or water treatment device 10, based on the settings stored in the ACPU 112 and/or processor/memory 24, as shown in block 916: You can decide whether to accept the upgrade. If the selected home therapy machine 100 and/or water treatment device 10 choose not to upgrade, the process 900 ends as indicated at block 916 and an end block. If any of the selected home therapy machines 100 and/or water treatment devices 10 accept the upgrade, the corresponding patient is prompted for the upgrade via the user interface 122, as shown in block 918. Confirm if you want to install it. If the patient has not opted to upgrade the selected home therapy machine 100 and/or water treatment device 10 via user interface 122, process 900 continues as indicated at block 920 and an end block. finish. If the patient chooses to upgrade(s) the selected home therapy machine 100 and/or water treatment device 10 via the user interface 122, one of them is upgraded as shown in block 922. Or multiple upgrades are performed and the home therapy machine 100 notifies the patient via the user interface 122 that the software has been upgraded. In some countries, the law requires patient approval before upgrading the patient's firmware. In one embodiment, the system 110 may require only home therapy machines 100 in countries that require patient approval to prompt the patient to accept the firmware upgrade at blocks 918 and 920 .

[00123] The home therapy machine 100 may retain the ability to revert to previous software versions of either the machine 100 or the device 10 or both. For example, if a firmware upgrade is corrupted, or if the home therapy machine 100 or water treatment device 10 firmware is corrupted, in one embodiment, the home therapy machine 100 reverts to the previous uncorrupted software version. be able to. Alternatively, the home therapy machine 100 may not be able to revert to previous software versions. Here, if the software is damaged or has been damaged, install new software, or replace the home treatment machine 100 or water treatment device 10 with a new home treatment machine 100 or water treatment device 10. exchange with

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

[00125] As noted above, any software updates for the water treatment device 10 may also be sent to the water treatment device 10 via the home therapy machine 100. FIG. The home therapy machine 100 can receive combined software upgrades that include software upgrades for both the home therapy machine 100 and the water treatment device 10 . Alternatively, upgrades can be delivered separately. The ACPU 112 then parses the software content of the home therapy machine 100 to separate it from the software content of the water treatment device 10 . In particular, the ACPU 112 can recognize which software content is intended for the home therapy machine 100 and which software content is intended for the water treatment device 10 . For example, the software content may essentially look like content specific to either the home therapy machine 100 or the water treatment device 10, or may be content specific to either the home therapy machine 100 or the water treatment device 10. can include Alternatively, software content may be flagged as intended for home therapy machine 100 or for water treatment device 10 . The home therapy machine 100 then 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 home components of system 110, such as tablet 122, blood pressure monitor 104 and/or scale 106, for example.

Clinician dashboard with rule evaluation
[00127] A clinician can view a list of that clinician's patients and a file for each patient that shows how the patient's treatment has been performed. The treatment file is derived from the home therapy machine 100 log file, including actual achieved flow rate, ultrafiltrate removal, actual achieved ultrafiltration rate, blood pressure during treatment, weight, and the like. The log file may also contain treatment data for the water treatment device 10 as described above. Examples of stored water treatment device 10 treatment data include: total purified water volume delivered, average water temperature, average water pressure, number of delivery requests from machine 100, warning and alarm information, chlorine/chloramine levels, and/or Use of components or exchange information, etc. can be mentioned.

[00128] The clinician has a list of patients, for example, hemodialysis (e.g., subdivided into short daily, overnight, alternate day, alternate night, etc.), peritoneal dialysis (e.g., continuous circulation peritoneal dialysis (CCPD), tidal, etc.). subdivided), the type of treatment the patient received, the attending physician, or the notices described below. Clinicians can also view patient photos and overviews for weekly, monthly, or other time periods.

[00129] The web portal 150 provides a clinician dashboard with notifications regarding events that occur during the procedure. In one embodiment, these notifications include color-coded flags, with individual colors corresponding to different notification states. The clinician can choose which events generate red or yellow flags visible on the dashboard. In one embodiment, flag settings are clinic specific and not patient specific. Thus, choosing to be notified about a particular event applies to all patients at that clinic or all patients seen by that clinician. For example, a clinician can set a rule that a yellow flag will appear on the dashboard if the duration of treatment was less than 4 hours. This rule will apply to all patients at that clinic or all patients seen by that clinician. The dashboard shows all patients who had a treatment less than 4 hours in duration, for example by a yellow flag. These flags may also relate to the water treatment system 10, e.g., post a flag when the useful life of a disposable component of the water treatment system 10 is less than 10 hours, or test chlorine/chloramine can post a red flag if it reaches a certain level.

[00130] FIG. Dashboard screen 1000 is, in one embodiment, the first screen a clinician sees upon logging into web portal 150 . The dashboard screen 1000 shows an overview of the patients being treated at the clinic and how the treatment by the home therapy machine 100 and water treatment device 10 has been performed.

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

[00132] Various icons 1004, 1006 and 1008 show information about procedures 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 treatment performed by home therapy machine 100 and water treatment device 10 was successful. Icon 1006 can be used to notify the clinician of events that are not critical and do not require immediate attention, but should be closely monitored in the future. For example, icon 1008 can be used to notify the clinician of an event that requires immediate attention.

[00133] The user can access the description using link 1018. When the user selects link 1018, a pop-up window or new screen 1050 appears. FIG. 10B shows an exemplary instructional screen 1050 displayed on the clinician's display 192 that describes various icons that may appear on the dashboard screen 1000 . Icon 1004 indicates that the results of the treatment performed by home therapy machine 100 and water treatment device 10 were "OK". Icon 1008 indicates a high priority flag. Icon 1006 shows a normal priority flag. Icon 1010 indicates that there was no communication with the home therapy machine 100 associated with that patient for a particular therapy.

[00134] In one embodiment, the dashboard also displays information collected by the water treatment device 10 in the water treatment device 10 log file.
