Summary of the Invention

Problems to be Solved by the Invention

[0005] However, although the prior arts shown in Patent Documents 1 and 2 have solved to some extent the problems such as the movement of artificial dialysis devices and the efficient use of dialysis fluid, there still remain problems in accessing disaster-stricken areas where roads are cut off like during natural disasters, and in providing emergency and continuous artificial dialysis treatment with limited resources.

[0006] In particular, in a situation where it is difficult to stably supply the water essential for dialysis fluid, it is difficult to perform sufficient artificial dialysis treatment to maintain the health of artificial dialysis patients. Therefore, there is a demand for the development of a system that can provide artificial dialysis treatment to patients (artificial dialysis patients) who require artificial dialysis even during emergencies such as natural disasters quickly and continuously.

[0007] Therefore, an object of the present invention is to provide an emergency dialysis system that can stably and continuously supply dialysis water even in disaster-stricken areas such as natural disasters.

Effect of the Invention

[0015] According to the first invention, since it is possible to draw water from natural water sources even in disaster-stricken areas such as natural disasters and purify and supply dialysis water, stable and continuous supply of dialysis fluid can be achieved even when existing infrastructure such as water supply and drainage systems and electricity fails. That is, even when a natural disaster occurs, artificial dialysis patients can continue to receive artificial dialysis treatment without interruption. In addition, since temporary houses and waste treatment facilities are also included, the safety and health of artificial dialysis patients during natural disasters can be maintained.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In the following, the same elements in all the drawings are denoted by the same reference numerals, and redundant descriptions are omitted. Also, in the description in the text, the reference numerals described above will be used as necessary.

[0024] The overall configuration diagram of the emergency dialysis system 1 which is an embodiment of the present invention is shown in FIG. 1, and the X-X line cross-sectional view of the temporary house 15 shown in FIG. 1 is shown in FIG. 2 respectively. The emergency dialysis system 1 of the present invention is roughly divided as shown in FIG. 1, and is formed by an emergency dialysis unit 10 for obtaining dialysis water for artificial dialysis patients and a management and control unit 50 for managing and controlling the emergency dialysis unit 10. The configuration diagram of the emergency dialysis unit 10 shown in FIG. 1 is shown in FIG. 3, and the configuration diagram of the management and control unit 50 shown in FIG. 1 is shown in FIG. 4 respectively.

[0025] The emergency dialysis unit 10 that performs artificial dialysis using dialysis water for artificial dialysis patients takes raw water from a natural water source as shown in FIGS. 1 and 3, and has a water intake device 11 that removes foreign substances through a filter, and the raw water obtained from the water intake device 11 is purified into dialysis water by biological treatment, physical treatment, and reverse osmosis treatment. A water purification device 20, artificial dialysis devices 13A to 13E that perform artificial dialysis using the dialysis water generated by the water purification device 20, a waste treatment facility 14 that collects medical waste generated from the artificial dialysis devices 13A to 13E, and a temporary house 15 in which a plurality of hospital beds 30A to 30E and artificial dialysis devices 13A to 13E are installed indoors. In addition, the water intake device 11, the water purification device 20, the artificial dialysis devices 13A to 13E, and the drainage storage tank 12 are connected to each other using a plurality of pipes H, enabling the pumping of raw water, dialysis water, dialysis drainage, etc. between the devices.

[0026] That is, the emergency dialysis unit 10 is equipped with a water intake device 11 that draws raw water from a natural water source and removes foreign substances through a filter. The raw water obtained by the water intake device 11 is sent to the purified water treatment device 20, where it is purified into dialysis water through biological treatment by the biological treatment device 21, physical treatment by the physical treatment device 22, and reverse osmosis treatment by the reverse osmosis treatment device 23. This dialysis water is stored in a storage tank 24 equipped with a device for maintaining water quality, stably supplied to the artificial dialysis devices 13A to 13E, and dialysis treatment is performed on artificial dialysis patients.

[0027] Furthermore, medical waste generated from the artificial dialysis devices 13A to 13E is appropriately collected and processed by the waste treatment facility 14. Also, the emergency dialysis system 1 includes a temporary building 15, where a plurality of hospital beds 30A to 30E and artificial dialysis devices 13A to 13E are installed as shown in FIGS. 1 and 2. This temporary building 15 enables the rapid accommodation and artificial dialysis of artificial dialysis patients even during natural disasters. Hereinafter, the details of each component of the water intake device 11, the purified water treatment device 20 (biological treatment device 21, physical treatment device 22, reverse osmosis treatment device 23, storage tank 24), the artificial dialysis devices 13A to 13E, the waste treatment facility 14, and the temporary building 15 will be described.

[0028] <Water intake device 11> The water intake device 11 is a device that plays an important role as a raw water supply source in the emergency dialysis system 1. This device draws raw water from a natural water source (e.g., seawater, rivers, lakes, groundwater, etc.) and performs treatment so that its water quality meets the requirements for dialysis water. The water intake device 11 is equipped with a filter, which is used to remove sediment and large foreign substances (such as garbage and seafood) in the raw water. This filter has a multi-layer structure and effectively functions as a pretreatment for dialysis water to efficiently remove physical obstacles. Also, the filter has a structure that automatically rotates or vibrates using the water flow to prevent foreign substances from clogging the filter.

[0029] Furthermore, the water intake device 11 may be equipped with an automatic water intake function so that stable water intake can continue even during natural disasters or power outages. For example, when the power is cut off, an emergency battery can be activated to prevent the water intake operation from stopping. In addition, it is also equipped with a mechanism for adjusting the water intake volume, and can be controlled to supply the required amount of water for artificial dialysis without excess or deficiency.

[0030] <Water purification device 20> The water purification device 20 is a device for purifying the raw water supplied from the aforementioned water intake device 11 into dialysis water, and includes three main treatment devices: a biological treatment device 21, a physical treatment device 22, and a reverse osmosis treatment device 23 described later, and a storage tank 24 for supplying the generated dialysis water to the artificial dialysis devices 13A to 13E with stable water quality and water volume. The details of each treatment device and treatment content of these biological treatment device 21, physical treatment device 22, and reverse osmosis treatment device 23 will be described below.

[0031] (Biological treatment device 21) The biological treatment device 21 is a device that performs so-called biological treatment to decompose and remove organic substances contained in raw water using aerobic bacteria. In this biological treatment, organic pollutants contained in the raw water are decomposed by microorganisms, ensuring the safety of the dialysis water. Since aerobic bacteria require oxygen, appropriate oxygen supply is also carried out, and the treatment efficiency is improved by enhancing the activity of the microorganisms.

[0032] (Physical treatment device 22) The physical treatment device 22 is a device that performs so-called physical treatment to physically remove impurities such as suspended matter and minute solids contained in raw water by adsorption means. As typical adsorption means, activated carbon filters and sand filters are used, and fine impurities and dissolved substances are adsorbed and removed. By this physical treatment, residues and chemical pollutants in the water are significantly reduced.

[0033] (Reverse osmosis treatment device 23) The reverse osmosis treatment device 23 is the final-stage device that performs a so-called reverse osmosis treatment to generate dialysate water from raw water using a reverse osmosis membrane (RO membrane). Since the reverse osmosis membrane has very fine pores and the property of not allowing impurities other than water molecules to pass through, fine substances such as salts, heavy metals, and bacteria can be effectively removed by filtering water at the molecular level through the reverse osmosis membrane. The water generated by this treatment can obtain a high purity that meets the standards as dialysate water.

[0034] (Storage tank 24) The storage tank 24 is a device that temporarily stores the dialysate water generated by the reverse osmosis treatment device 23 and then supplies it to the artificial dialysis devices 13A to 13E. In addition, the storage tank 24 has a function of adjusting the balance between the supply amount and the demand amount of the dialysate water, and can flexibly respond to the intermittent operation status and demand fluctuations of the reverse osmosis treatment device 23. That is, by the cooperation of the storage tank 24 and the above-mentioned three types of treatment devices, the raw water taken from the natural water source is purified into safe and high-quality dialysate water. The thus purified dialysate water is once stored in the storage tank 24, eliminating the gap between the supply amount of the reverse osmosis treatment device 23 and the demand amount of the artificial dialysis devices 13A to 13E, and stably supplied to the artificial dialysis devices 13A to 13E described below, providing a safe and effective treatment for artificial dialysis patients.

[0035] In addition to the three types of treatment devices, when the raw water and the drainage water taken circulate, the pH may fluctuate. Therefore, a pH adjustment tank can also be installed in the water purification device 20. In this pH adjustment tank, a treatment for stabilizing the pH value of the water is performed to maintain the quality required for dialysate water. Thereby, the quality of the water supplied to the artificial dialysis devices 13A to 13E described below is consistently ensured, enabling a safe and effective treatment for artificial dialysis patients.

[0036] <Artificial dialysis devices 13A to 13E> The artificial dialysis devices 13A to 13E are devices that perform blood purification on artificial dialysis patients using the dialysis water supplied from the aforementioned water purification device 20. The artificial dialysis devices 13A to 13E have the function of purifying blood by passing it through a dialysis membrane and removing waste products and excess water from the body. These artificial dialysis devices 13A to 13E are equipped with a blood pump, a dialysis fluid pump, and a monitoring system, and can perform dialysis while constantly monitoring the blood pressure and body fluid balance of artificial dialysis patients.

[0037] In addition, the artificial dialysis devices 13A to 13E are also equipped with an emergency power supply and are designed to operate stably even during power outages associated with natural disasters. Furthermore, they have the flexibility to finely adjust dialysis conditions according to the condition of artificial dialysis patients, and can also provide artificial dialysis treatment optimized for individual artificial dialysis patients.

[0038] <Waste treatment facility 14> The waste treatment facility 14 is a facility that collects and treats medical waste discharged from the aforementioned artificial dialysis devices 13A to 13E. Blood, body fluids, used filters, and other waste generated during artificial dialysis carry an infection risk, so they need to be treated safely and quickly. In this waste treatment facility 14, waste classification and detoxification treatment are carried out, and appropriate treatment can be carried out in compliance with legal regulations.

[0039] In addition, the waste treatment facility 14 has a mechanism for automatically collecting waste by providing a pipeline directly connected to the artificial dialysis devices 13A to 13E, and can improve the efficiency of treatment. Furthermore, it is also equipped with a filtering system to minimize the impact on the environment, and can also perform appropriate waste treatment.

[0040] <Temporary housing 15> The temporary housing 15 has a structure that allows a plurality of hospital beds 30A to 30E and artificial dialysis devices 13A to 13E to be installed indoors as shown in FIGS. 1 and 2 so that the emergency dialysis system 1 can operate quickly during natural disasters. This temporary housing 15 is designed to be installable in a short period of time, such as a prefabricated house, and can be quickly deployed and installed in the disaster area when a natural disaster occurs. The temporary housing 15 provides a space where artificial dialysis patients can receive artificial dialysis treatment with confidence while maintaining a clean environment indoors. By the above elements cooperating with each other, it becomes possible for artificial dialysis patients to receive stable artificial dialysis treatment even during natural disasters.

[0041] In addition, the emergency dialysis unit 10 can be provided with a drainage storage tank 12 that efficiently treats and reuses the drainage generated by artificial dialysis. The drainage storage tank 12 can temporarily store dialysis drainage, concentrated water generated by reverse osmosis treatment, and the like. Also, by attaching an ultraviolet sterilization device to the drainage storage tank 12, it becomes possible to safely reuse the drainage by preventing the propagation of various bacteria. That is, by safely reusing the drainage generated by the above-described water purification process and the operation of the artificial dialysis procedure, it is possible to contribute to improving the sustainability of the region.

[0042] Next, as shown in FIG. 4, the management control unit 50 includes a measuring means 51 for monitoring the operating status of the emergency dialysis unit 10, a control means 52 for controlling the operation of the emergency dialysis unit 10 based on the measured values of the measuring means 51, a communication means 53 for communicating between the management control unit 50 and the emergency dialysis unit 10, a remote connection means 54 for connecting to the management control unit 50 from a remote location using a telecommunication line, and a power supply means 55 for supplying power to the emergency dialysis unit 10 and the management control unit 50.

[0043] That is, the management control unit 50 includes a measuring means 51 for monitoring the operating status of the emergency dialysis unit 10, and a control means 52 for controlling the operation of the emergency dialysis unit 10 based on the measured values obtained from the measuring means 51 is arranged. Also, a communication means 53 for communicating between the management control unit 50 and the emergency dialysis unit 10 is installed, whereby the cooperation between the two is smoothly carried out.

[0044] As one of the important features of the present invention, the management control unit 50 includes remote connection means 54 that enables connection from a remote location using a telecommunication line. With this remote connection means 54, even when there are no staff members (mainly medical staff) who can operate the system in the disaster-stricken area during a natural disaster, the operation status of the emergency dialysis system 10 can be monitored and controlled. In addition, power supply means 55 for supplying power to the entire system (management control unit 50 and emergency dialysis unit 10) is also provided, and it is possible to ensure stable power supply even in an emergency such as a power outage due to a natural disaster.

[0045] Hereinafter, the details of each component of the measurement means 51, control means 52, communication means 53, remote connection means 54, and power supply means 55 will be described. Note that a part of the management control unit 50 is installed in the staff room (waiting room for medical staff, etc.) of the temporary house 15 as shown in FIGS. 1 and 4, but it may also be installed outdoors.

[0046] <Measurement means 51> The measurement means 51 is a device that collects data necessary for monitoring the operation status of the emergency dialysis unit 10. Its main functions include monitoring the operation status of the water intake device 11, water purification device 20, and artificial dialysis devices 13A to 13E, the quality of water purification, and the performance of artificial dialysis treatment in real time, and acquiring data. Thereby, the operation state of the entire system can be accurately grasped, and information for quickly responding in case of an abnormality can be provided.

[0047] In addition, the measurement means 51 monitors the operation status of the emergency dialysis unit 10 using various sensors. For example, the water quality sensor monitors the purity of the output water of the water purification device 20 to ensure appropriate quality of the dialysis water. Furthermore, the operation status and power consumption status of the system are monitored, and the measured data is used by the control means 52 described later.

[0048] <Control means 52> The control means 52 is a central device for controlling each device in the emergency dialysis unit 10 based on the data obtained from the aforementioned measurement means 51. This control means 52 has a function of automatically adjusting the operation of the entire emergency dialysis unit 10 to maintain optimal operating conditions. For example, it can adjust the flow rate and pressure of the dialysis water, and manage the operating speed of the pure water treatment device 20 and the operating timing of the artificial dialysis devices 13A to 13E.

[0049] In addition, the control means 52 is equipped with an abnormality detection function. When an abnormality is detected based on the data from the measurement means 51, it quickly stops part or all of the system and issues an alarm. Furthermore, when the system is in a recoverable state, it can be programmed to automatically restart.

[0050] <Communication means 53> The communication means 53 is a device for performing two-way communication regarding information between the management control unit 50 and each device in the emergency dialysis unit 10. Here, "information" includes, for example, all information for operating (operating) the emergency dialysis system 1, such as the operating data of the artificial dialysis devices 13A to 13E, water quality, temperature, detection of foreign substances, filter status, power status, and alert signals. Through this communication means 53, the operating data and control commands of each device are transmitted and received in real time, enabling the entire emergency dialysis system 1 to cooperate smoothly. In addition, the communication means 53 mainly exchanges data via a wired or wireless communication network.

[0051] As a result, for example, the operating state of the water intake device 11 and the water quality data of the pure water treatment device 20 are immediately reported to the management control unit 50, and appropriate commands are transmitted from the control means 52 as needed. In addition, the communication means 53 is designed to be connectable to an external monitoring system by cooperating with the remote connection means 54 described later, enabling the monitoring and control of the emergency dialysis system 1 from a remote location.

[0052] <Remote connection means 54> The remote connection means 54 is a device that provides a function enabling connection between the management control unit 50 and an external remote monitoring device or operator using a telecommunications line. Thereby, even when there are no technicians in the disaster area during a natural disaster, by cooperating with the aforementioned communication means 53, the operating status of the emergency dialysis system 1 can be monitored, and operations can be performed remotely as needed.

[0053] The remote connection means 54 uses a high-speed and stable communication line and can respond immediately in case of an emergency. Also, security measures are implemented, and an authentication process and data encryption technology for preventing unauthorized access from the outside are introduced. Thereby, the safety and reliability of the emergency dialysis system 1 are ensured.

[0054] <Power supply means 55> The power supply means 55 is a device for supplying power to the entire emergency dialysis system 1. Even when the lifeline, especially the power supply, is interrupted due to the occurrence of a natural disaster, an emergency power source is provided so that the emergency dialysis system 1 can continue to operate. This emergency power source uses a battery, a generator, etc., and enables the emergency dialysis system 1 to operate stably even under a power outage or unstable power supply situation.

[0055] Also, the power supply means 55 has a power generation function for efficiently managing the power consumption of the entire emergency dialysis system 1 and preferentially supplying the power required for each device. Thereby, as shown in FIG. 4, the power required for the management control unit 50 such as the measurement means 51 and the entire emergency dialysis unit 1 such as the water purification treatment device 20 via the distribution board is supplied, enabling operation over a long period of time and continuous artificial dialysis treatment for artificial dialysis patients without interruption. Each of the above elements cooperates to form the management control unit 50 and supports the operation of the entire emergency dialysis system 1. Thereby, it becomes possible to provide an environment in which artificial dialysis patients can receive treatment safely and stably even during a natural disaster.

[0056] In addition, in the emergency dialysis system 1 according to an embodiment of the present invention, as shown in FIG. 4, a warning device 60 may be provided in the management control unit 50. This warning device 60 has a function of automatically issuing a warning when an abnormal value is detected by the measurement means 51 or the control means 52. Here, the "case where an abnormal value is detected" includes, for example, the case where the water quality of the dialysis water deviates from the specified value, the case where an operation abnormality occurs in the artificial dialysis devices 13A to 13E, or the case where an abnormality occurs in the power supply means 55.

[0057] The warning device 60 issues a warning by means of a visual alarm (lighting of a warning lamp) or an auditory alarm (buzzer sound). It also has a function of transmitting a warning message to medical staff or administrators at a remote location via the remote connection means 54. This enables early detection of abnormalities in the emergency dialysis system 1 and prompt response.

[0058] Furthermore, as a countermeasure after abnormal detection, this warning device 60 can perform multi-stage responses including automatic stop of the emergency dialysis system 1 and switching to backup operation. Thus, the emergency dialysis system 1 is designed to be able to provide safe artificial dialysis treatment to artificial dialysis patients even when an abnormality occurs.

[0059] In addition, as shown in FIG. 4, the management control unit 50 may include a medical record management unit 70 for centrally managing the electronic medical records of artificial dialysis patients. The medical record management unit 70 has a function of databaseing the past medical history and current treatment status of artificial dialysis patients and managing them integrally within the emergency dialysis system 1. This makes it possible to grasp the medical information of artificial dialysis patients in real time and perform appropriate artificial dialysis treatment.

[0060] Specifically, the medical record management unit 70 records the blood test results, dialysis history, type of dialysis fluid used, and even the physical condition changes during artificial dialysis of artificial dialysis patients. For example, by adopting the standard format of the electronic medical record of artificial dialysis patients, it can be used consistently in different artificial dialysis facilities in different regions.

[0061] In addition, these pieces of information are also used in cooperation with other devices of the emergency dialysis system 1. For example, a mechanism can be established to quickly and accurately manage the medical data of artificial dialysis patients by integrating with the personal information associated with the My Number (registered trademark) held by each artificial dialysis patient. Furthermore, through the management of medical records on the cloud, the medical record data can be shared in real time without being lost even during natural disasters, enabling a prompt response to artificial dialysis treatment. When operating the emergency dialysis system 1 of the present invention, for example, regarding the management of medical record data, only those who have received specific training and are registered staff are allowed to view it. In addition, those who access the medical record data of all artificial dialysis patients stored on the cloud are limited to those who have signed a confidentiality agreement.

[0062] Furthermore, the medical record management unit 70 can also share data with medical institutions in remote locations, enabling seamless utilization of medical information even when artificial dialysis patients receive treatment at different locations. That is, when the artificial dialysis devices 13A to 13E adjust the dialysis conditions, the data of the medical record management unit 70 is referred to, and the optimal condition settings for each artificial dialysis patient are automatically reflected. This function enables the establishment of a system that can continue appropriate artificial dialysis treatment even when the evacuation location changes after a natural disaster.

[0063] Next, a series of processes (steps) for performing artificial dialysis treatment using the emergency artificial dialysis system of the present invention will be described. A flowchart of artificial dialysis treatment using the emergency artificial dialysis system 1 shown in FIG. 1 is shown in FIG. 5. This series of steps consists of six steps: procurement of raw water (first step: S001), purification treatment of raw water (second step: S002), supply of dialysis water and start of artificial dialysis (third step: S003), drainage management after dialysis (fourth step: S004), remote operation and management (fifth step: S005), and maintenance and preparation for the next treatment (sixth step: S006), as shown in FIG. 5. Details of each step will be described below.

[0064] <Procurement of Raw Water: First Step S001> As a first step, raw water used for hemodialysis treatment is procured. Natural water sources such as rivers, lakes, well water, and seawater are used as the water intake sources. Stable supply of raw water from these natural water sources is a prerequisite for purification treatment. The equipment required for water intake varies depending on the water intake source. For example, when taking water from a river, appropriate equipment is installed at the water intake to cope with seasonal water volume fluctuations and natural disasters such as floods. When using well water, since fluctuations in the groundwater level are a problem, the water level is monitored regularly from daily life and managed to maintain a stable supply. Thereby, the raw water is supplied without interruption.

[0065] When taking in raw water, foreign substances such as gravel, dead leaves, and garbage may flow in with the water. To prevent this, a filter is installed at the water intake. The filter effectively removes foreign substances of different sizes according to the mesh size and plays a role in preventing clogging and damage to the water intake system. In addition, the filter can be cleaned or replaced after a certain period of time to ensure continuous efficient water intake.

[0066] <Purification treatment of raw water: Second step S002> In the second step, the procured raw water is purified. This treatment includes three main treatment stages: biological treatment, physical treatment, and reverse osmosis treatment. First, in biological treatment, the organic matter contained in the raw water is decomposed by aerobic bacteria. Aerobic bacteria are microorganisms that require oxygen and can efficiently decompose organic matter. The decomposed substances are collected in the sedimentation tank as sludge and removed regularly.

[0067] After the biological treatment is completed, physical treatment is then carried out. At this stage, multiple filters are used to remove impurities and fine particles remaining in the water. Specifically, activated carbon filters are used to adsorb harmful chemical substances and odor components. In addition, the porous filter further enhances the cleanliness by physically capturing finer impurities.

[0068] The final step is reverse osmosis. Reverse osmosis is essential to remove very fine impurities and dissolved substances from the water. In this process, a high-pressure pump is used to pass the raw water through a reverse osmosis membrane, allowing only the water molecules to pass through.

[0069] This completely removes impurities, including salts and other dissolved substances, and produces water of very high purity. This water meets the standards for medical use, especially for dialysis. The purified water produced by reverse osmosis is further stored and distributed according to its subsequent use. This ensures a stable supply of the required purified water for dialysis and other medical uses. Note that in this second step, biological treatment can be omitted depending on the condition of the raw water.

[0070] <Supply of dialysis water and start of dialysis: third step S003> In the third step, purified water that has been purified is supplied to the dialysis device and dialysis is started. This step begins by sending purified water to the dialysis device. Water purified to a high purity by reverse osmosis is optimized as dialysis water, enabling safe and effective dialysis treatment for dialysis patients. This purified water comes into contact with the blood of the dialysis patient during dialysis treatment and plays an important role in removing waste products and excess water from the blood.

[0071] After supplying the dialysis water, dialysis is performed. Dialysis is a process in which the blood of the dialysis patient is taken out of the body and waste products and excess water are removed through the dialysis membrane. The dialysis water absorbs waste products through the dialysis membrane, and clean blood is returned to the body. This series of processes allows dialysis patients with impaired kidney function to maintain the balance of waste products and water in the body.

[0072] The amount and quality of water supplied during artificial dialysis need to be precisely controlled. In a series of steps for performing artificial dialysis using the emergency dialysis system of the present invention, an automatic control program is introduced, the supply amount and water quality of dialysis water are monitored in real time, and optimal conditions during artificial dialysis are always maintained. The automatic control system monitors the temperature, pressure, flow rate of water, and furthermore, the water quality, and manages so that the artificial dialysis device can always exhibit the best performance.

[0073] <Post-dialysis drainage management: Step 4 S004> The fourth step is the management of the drainage generated after artificial dialysis. The dialysis water used during artificial dialysis and the concentrated water generated by the reverse osmosis treatment device are not directly discharged, but first collected in a drainage storage tank. Since this drainage contains waste and dissolved substances, it needs to be appropriately treated. The drainage storage tank is installed outdoors and is equipped with facilities for safely treating the drainage.

[0074] The drainage collected in the drainage storage tank is treated using an ultraviolet sterilization device. This device prevents the growth of miscellaneous bacteria that may be contained in the drainage. Ultraviolet sterilization is a safe sterilization method that does not use chemicals, and ensures the safety of the drainage while minimizing the impact on the environment.

[0075] Also, the pH adjustment of the drainage is an important step. Since the pH of the drainage may not meet the environmental standards as it is, it is adjusted to an appropriate pH value in an adjustment tank. Thereby, drainage treatment considering the environment is realized, and it is guaranteed that the drainage is safely discharged to the outside. This pH adjustment is automated and managed so that the optimal pH is always maintained.

[0076] <Remote operation and management: Step 5 S005> In the fifth step, the supply of dialysis water and the operating status of the hemodialysis device are remotely monitored. This remote monitoring system can grasp the operating status of the hemodialysis device and fluctuations in water quality in real time, and has a function of immediately issuing a warning in case of any abnormality. Based on the operating status of the hemodialysis device, instructions for replenishing chemicals and replacing parts are remotely issued as necessary.

[0077] Furthermore, in the event of a natural disaster, it is also possible for a skilled person to remotely operate the hemodialysis device. For example, even when a mechanical trouble occurs, the hemodialysis device can be safely stopped or changed to necessary settings by remote operation, thereby ensuring the safety of hemodialysis patients. This remote operation function is also useful when the hemodialysis device is in a remote location or when there is no specialist in the disaster area.

[0078] <Maintenance and Preparation for the Next Time: Sixth Step S006> In the sixth step, maintenance of the hemodialysis device is carried out after the end of hemodialysis. Since the hemodialysis device is used frequently, regular maintenance is essential. In a series of steps for performing hemodialysis using the emergency hemodialysis system of the present invention, a function is incorporated to automatically notify the timing when it is necessary to replace the filter and replenish the chemicals based on the operating status and usage time of the hemodialysis device. Thereby, it is possible to prevent omission of maintenance and malfunction of the device.

[0079] Another important step after the end of hemodialysis is electronic medical record management. All the treatment details and the status of hemodialysis patients during hemodialysis are automatically recorded in the electronic medical record. Thereby, preparations for the next hemodialysis treatment can be efficiently carried out, and medical staff such as doctors and nurses can make an appropriate treatment plan based on the detailed data for each hemodialysis patient.
