In general, hemodialysis, peritoneal dialysis, and kidney transplantation are methods that can sustain life for patients with chronic renal failure who have lost kidney function due to various diseases.

In the kidney transplant method, the family, relatives, and kidneys can receive kidneys from healthy brain lions, but kidney transplantation can be performed only if various examinations determine that the provider is completely healthy and that one kidney can be healthy after surgery. In addition, since there are extremely limited providers of kidneys, most patients with chronic renal failure rely on hemodialysis and peritoneal dialysis.

On the other hand, hemodialysis and peritoneal dialysis methods are neotherapy for patients with chronic renal failure, and the blood accumulated in waste patients and dialysis fluids similar in composition to the extracellular fluid of normal humans flow in opposite directions, such as elements accumulated in blood. The principle is to remove the wastes by the principle of diffusion by the difference in concentration and to make the difference of hydrostatic pressure and to filter the plasma to remove the excess water in the body.

Among them, the hemodialysis method should be dialyzed using a hollow fiber membrane dialysis machine (aka artificial kidney) after the patient has visited the hospital. Usually, treatment time should be dialyzed 4 hours once a week and 12 hours a week for 3 times a week. The patient's blood is completely purified.

However, the hollow fiber membrane dialysis machine used in the above-mentioned hemodialysis method is usually discarded after only 4 hours of use to one patient, and another hollow fiber membrane dialysis machine should be used. There is a problem of not receiving medical treatment.

2A is an exemplary diagram of a DRS control screen implemented in a terminal applied to the present invention, and shows a control screen for controlling the operation of the dialysis machine reuse apparatus (DRS) 200.

In this case, as shown in FIG. 2A, the control screen 170 for controlling the DRS 200 includes a menu selection unit 171 and the DRS (which includes various menus necessary for controlling the DRS 200). And a status display unit 172 for outputting basic status information when 200 is operated.

On the other hand, the menu selection unit 171 is' Prepare ',' Process (play) ',' Sanitize ',' Reset ',' Start 'and' Stop (stop) And menus.

In this case, the 'prepare' menu is to wash the upper and lower blood lines 271 and 275 and the upper and lower dialysis fluid lines 272 and 274 of the DRS 200 with RO water, and the 'process' menu is the upper and lower blood lines ( 271 and 275 and the dialysis machine 400 connected to the upper and lower dialysis solution lines 272 and 274 to wash the RO dial and the washing solution (alkaline water) to fill the dialysis machine 400 with disinfectant solution (citric acid), and the 'Sanitize' The menu is for washing the upper and lower blood lines 271 and 275 of the DRS 200 and the upper and lower dialysis fluid lines 272 and 274 with a washing liquid (alkaline water).

The 'Stop' menu is to stop the operation of each menu of the menu selection unit 271.

Meanwhile, the status display unit 172 may be configured as a menu such as 'step', 'pH' and 'volume'. At this time, the 'step' indicates the progress step for each menu of the Prepare, Process and Sanitize. In addition, 'pH' and 'volume' indicate hydrogen ion index and volume change of the dialyzer 400 connected to the DRS 100 during the process. In addition, although not shown in the drawing, the status display unit 172 may further include a variety of information required during each process is output.

That is, when the user selects any one menu of the menu selection unit 171 through the input unit 130, the control unit 120 of the terminal transmits a control signal according to the selected menu through the DRS (Network). And the control unit 220 of the DRS 200 receiving the control signal turns on and off valves connected to the lines 272, 274, 271 and 275 according to the control signal. The cleaning and disinfection process as described above is to be carried out.

On the other hand, when the DRS 200 under the control as described above briefly described the process of washing the dialyzer 400 as follows.

First, as a preparation process by the 'Prepare' menu, the blood line and the dialysate line of the DRS 200 are washed with RO water. That is, a process of washing the inside of the DRS 200 is performed before the 'Process' process. Thereafter, the dialysis machine 400 performing the dialysis process is connected to the DRS 200 using the clamp 273.

Next, as a process by the 'Process (regeneration)' menu, the dialyzer 400 which performs the dialysis process using RO water and alkaline water is washed and disinfected. At this time, the blood volume (blood volume) for the dialysis machine 400 is calculated, and the integrity of the dialysis membrane is examined through a pressure test. Thereafter, by filling 1.5% to 2% citric acid in the dialysis machine 400, which has been cleaned and disinfected, the 'Process (regeneration)' process for the dialysis machine is completed.

Next, a disinfection process for the DRS 200 is performed by the 'Sanitize' menu. In this case, alkaline water is filled in all the connection tubes of the DRS 200. That is, the 'Sanitize (disinfection)' process is a storage mode for cleaning and disinfecting the DRS 200 itself after detaching the dialysis machine 400 from the clamp of the DRS 200. Thereafter, in order to perform the regeneration process for another dialysis machine 400, the alkaline water is discharged and then performed from the 'prepare' process.

Finally, the dialysis machine 400 cleaned and disinfected through the above processes is vacuum-packed after a label on which necessary information such as user, volume, and washing date of the dialysis machine is attached is attached.

Meanwhile, the dialysis machine 400 vacuum-packed after being washed and disinfected in the DRS 200 through the above processes is a predetermined temperature (preferably 85 ° C. to 95 ° C.) in the oven 300 through the processes to be described below. Heat treatment for a predetermined time (preferably 12 hours to 20 hours). That is, the dialysis machine 400 is heated and sterilized at about 95 ° C. for 20 hours (or 12 hours at 85 ° C. or more). At this time, the oven 300 is preferably set so that the temperature is gradually increased (for example, it can be set to increase to 95 ° C. over 80 minutes) to prevent the dialysis machine from suddenly expanding.

The above process is as follows. That is, the DRS 200 is left in the dialysis machine 400 by forward washing and reverse washing the dialysis machine 400 by using the flow rates of RO water and washing liquid (alkaline water) under the control of the terminal 100. The blood clot from the patient is removed, and the dialysis machine 400 filled with citric acid (disinfectant solution) is, in the oven 300, 12 hours at 85 ° C. (actually, 20 hours at 95 ° C.) or more. Disinfection is completed by heat treatment.

In this case, the DRS 200 is driven according to a control signal transmitted from the terminal 100 to clean and disinfect the dialysis machine 400, but is not limited thereto. That is, the DRS 200 may perform the above function by the control signal input through the input unit 230 of the DRS 200, not the control signal transmitted from the terminal 100 through a network. have.

In other words, the DRS 200 may be driven by a control signal transmitted from the terminal 100 connected through a network, but the control signal input by the user through the input unit 230 provided in the DRS 200 itself. It may be driven by.

In the case where the DRS 200 is controlled through a network through the terminal 100, the above process may be continuously performed for a plurality of DRSs 200.

That is, a user can select the menu selection unit 171 outputted to the terminal 100 or a DRS 200 selection button (not shown) on a separate control screen (not shown). One of the plurality of DRS (200) DRS (200) can be selected to perform the above control process, and after selecting another DRS (200) cleaning and disinfection process in the plurality of DRS (200) Can be controlled.

Alternatively, as in the monitoring screen 180 shown in FIG. 2B, the control screen 170 for the plurality of DRSs may be simultaneously controlled.

2B is an exemplary diagram of a DRS monitoring screen implemented in a terminal applied to the present invention, and shows a monitoring screen for monitoring various types of information according to the operation of the dialysis machine reuse apparatus (DRS) 200.

That is, as illustrated in FIG. 2B, the monitoring screen includes a plurality of monitoring units 190 outputting status information of each of the plurality of DRSs 200 connected to the terminal 100.

On the other hand, the monitoring unit 200, as shown in Figure 2b, the information of the DRS 200 (for example, the device information of the DRS 200, the model name of the dialyzer 400 mounted on the DRS, Patient to display at least one of the patient's name, chart number, first use date, and playback count of the patient using the dialysis machine 400, the status display unit 191 for displaying whether the DRS is connected or the like; And an information display unit 193 for displaying information (eg, capacity, pressure, PH, etc.) according to the washing and disinfection in the DRS 200.

At this time, the model name of the dialyzer of the information displayed on the status display unit 191 may be directly input by the user through the input unit 130 of the terminal 100 (input using a keypad or attached to the dialyzer Input using a bar code), an input using the input unit of the DRS 200 (an input using a keypad or an input using a barcode attached to the dialysis machine) may be output by the control unit 110 via a network. have.

In addition, the information output to the patient information display unit 192 may be directly input by the user through the input unit 130 of the terminal 100, it is input through the input unit 230 of the DRS (200) The control unit 120 may be received and output through the network.

In addition, the controller 120 of the terminal detects information, such as capacity, pressure, PH, and the like, which is output to the result display unit 193 by the sensing unit 260 of the DRS 200 by various sensors. It may be received and output.

On the other hand, the process of the user washing and disinfecting the dialyzer 400 using the control screen 170 and the monitoring screen 180 as described above will be described in detail. That is, a method of monitoring a washing and disinfecting state of the plurality of DRS 200 and the dialyzer 400 while the user controls the plurality of DRS 200 to clean and disinfect the plurality of dialyzers 400 is illustrated in FIG. This is described in detail with reference to 2a and 2b.

In this case, the control of each of the DRS 200 may be not only implemented by the terminal 100 as described above, but also controlled by the controller 220 provided in each DRS 200. , Monitoring is implemented in the terminal 100. Meanwhile, in the following description, in order to include both of the control methods, in the description of the control, the control through the control screen 170 is not distinguished from the control in the DRS 200 and the control in the terminal 100. I will explain.

First, the user turns on the power of the DRS 200 to be used, and at this time, the monitoring screen 180 shown in FIG. 2B, the power of the DRS 200 connected to the terminal 100 through a network Information about all the DRSs 200 in the on state is output.

Next, the user connects the dialysis machine 400 to be cleaned and disinfected to the DRS 200. At this time, the user inputs the information about the dialysis machine 400 to the terminal 100 by the method as described above, the control unit 120 of the terminal to the input information on the monitoring screen 180 Will print.

Next, the user cleans and disinfects the dialysis machine 400 using the 'Process' menu of the control screen 170. In this case, the controller 220 of the DRS 200 transmits the information transmitted through the detector 260 to the terminal 100 as described above, and the controller 120 of the terminal that has received the information. Outputs the information to the monitoring screen 180.

On the other hand, after the washing and disinfection process as described above, the control unit 120 of the terminal analyzes the information and displays whether or not the dialysis machine 400 can be reused on the monitoring screen 180. In other words, if it is impossible to reuse the analysis results of capacity, pressure, pH, etc., a message for requesting disposal is displayed. If repetitive cleaning and disinfection is required for reuse, a rerun message of 'Process' menu is output. It may be.

Next, after the user separates the dialyzer 400 from the DRS 200, the user disinfects the DRS 200 using the 'Sanitize' menu of the control screen.
