  Then, the blood pump 5 is driven in a state where the patient has punctured the arterial puncture needle a connected to the distal end of the arterial blood circuit 3a and the venous puncture needle b connected to the distal end of the venous blood circuit 3b. The blood of the patient passes through the arterial blood circuit 3a to the dialyzer 4 while being defoamed (removing bubbles) in the arterial air trap chamber 6, and after the blood purification is performed by the dialyzer 4, the blood on the venous side is obtained. The air returns to the patient through the venous blood circuit 3b while the air trap chamber 7 removes bubbles (removal of bubbles). This allows the dialyzer 4 to purify the patient's blood while circulating it extracorporeally from the tip of the arterial blood circuit 3a of the blood circuit 3 to the tip of the venous blood circuit 3b.

  The venous air trap chamber 7 is connected to a venous pressure sensor P capable of detecting a venous pressure based on the fluid pressure in the venous blood circuit 3b. It is configured to detect fluid pressure (venous pressure). Thus, the blood circuit 3 monitors the venous pressure of the blood circulating extracorporeally, so that the patient's condition change during the treatment can be grasped.

  The dialyzer 4 has, in its housing, a blood inlet 4a (blood inlet port), a blood outlet 4b (blood outlet port), a dialysate inlet 4c (dialysate channel inlet: dialysate inlet port), and a dialysate. An outlet 4d (dialysate flow path outlet: dialysate outlet port) is formed, of which the arterial blood circuit 3a is connected to the blood inlet 4a, and the venous blood circuit 3b is connected to the blood outlet 4b.

In the dialyzer 4, a blood flow path (a flow path between the blood inlet 4a and the blood outlet 4b) through which a patient's blood flows through a blood purification membrane and a dialysate flow path (a dialysate) through which a dialysate flows. A flow path between the inlet 4c and the dialysate outlet 4d) is formed. The hollow fiber membrane constituting the blood purification membrane is formed with a large number of minute holes (pores) penetrating the outer peripheral surface and the inner peripheral surface thereof, thereby forming a hollow fiber membrane. It is configured so that impurities and the like in blood can permeate into the dialysate.

  Further, the distal end of the arterial blood circuit 3a (near the connector c) and the distal end of the venous blood circuit 3b (near the connector d) according to the present embodiment are connected to the arterial blood circuit 3a or the venous side during the blood purification treatment. Bubble detectors (B1, B2) that can detect gas (bubbles) in the blood flowing through the blood circuit 3b are connected. Clamp means Va and Vb capable of closing or opening the flow path by opening and closing are attached to the distal end of the arterial blood circuit 3a (near the connector c) and the distal end of the venous blood circuit 3b (near the connector d). ing.

  On the other hand, while the dialysate adjusted to a predetermined concentration is sent to the dialyzer 4 to the dialysate introduction line L1 and the dialysate discharge line L2, waste products and the like (drainage) are discharged from the dialyzer 4 together with the dialysate. A double pump 9 is connected. That is, the double pump 9 is provided so as to straddle the dialysate introduction line L1 and the dialysate discharge line L2. By driving the dual pump 9, the dialysate is dialed into the dialysate introduction line L1 with respect to the dialyzer 4. And the dialysate (discharge) can be discharged through the dialysate discharge line L2.

  The dialysate introduction line L1 is connected to solenoid valves V1 and V3 and filtration filters F1 and F2, so that the dialysate to be introduced into the dialyzer 4 can be filtered by the filtration filters F1 and F2. , V3, the flow path can be cut off or opened at an arbitrary timing. The dialysate introduction line L1 is connected to the dialysate discharge line L2 at bypass lines L4 and L5, and the bypass lines L4 and L5 are connected to solenoid valves V4 and V5, respectively.

A bypass line L7 extends from between the pressurizing pump 11 and the compound pump 9 via a degassing chamber 12. Solenoid valves V2 and V7 are connected to the dialysate discharge line L2 and the bypass line L7 branched therefrom, respectively, so that the dialysate flow path can be shut off or opened at an arbitrary timing.

  The control means 13 is composed of a microcomputer electrically connected to various actuators, sensors, and the like included in the blood purification device 1, and has predetermined treatment conditions or operation settings (in the present embodiment, the central monitoring device 2 Based on the treatment condition or operation setting transmitted from the device), an operation for performing blood purification treatment (blood purification treatment step) or an operation related to the blood purification treatment (dialysis preparation step, blood return step, etc.) is performed. Things.

  More specifically, the control means 13 controls various actuators and sensors based on the treatment conditions or operation settings transmitted from the central monitoring device 2 to thereby control, for example, the dialysate flow in the blood circuit 3 and the dialyzer 4. Priming (dialysis preparation step) for filling the inside of the road with a priming liquid, blood purification treatment step for purifying the blood of the patient in the blood circuit 3 while circulating the blood extracorporeally, and returning the blood in the blood circuit 3 to the patient. The blood process and the like can be controlled so as to be sequentially performed.

  Here, the blood purification device 1 according to the present embodiment includes a registration unit 14 and a change unit 15. The registration means 14 can register in advance a treatment condition or an operation setting according to the performance, properties or function of the blood purifier. In the present embodiment, the registration can be made by inputting the information on the display means M. ing. For example, as a blood purifier registered by the registration means 14, the performance based on the difference in the membrane area of the purification membrane, UFR, etc., the property based on the presence or absence and the amount of the coating material applied to the purification membrane, and the purification of the hollow fiber The membrane is classified according to the function based on the difference in form such as a hollow fiber type or a laminated type as a membrane, and a treatment condition or an operation setting according to the performance, property or function can be registered.

  The change unit 15 registers the treatment condition or operation setting (the treatment condition or operation setting transmitted from the central monitoring device 2) in the registration unit 14 according to the blood purifier (dialyzer 4 or the like) used in the blood purification treatment. It can be changed to the treatment condition or operation setting. That is, when the blood purifier to be used is inputted by the display means M, the blood purifier is compared with the blood purifier registered by the registration means 14, and the blood purifier registered by the registration means 14 by the change means 15. Is automatically and collectively changed to the treatment condition or operation setting according to.

  Further, for example, the treatment conditions or operation settings registered by the registration unit 14 include a priming washing amount or washing time or a priming method in the dialysis preparation step, and an anticoagulant in the blood purification treatment step. Monitoring amount (infusion rate and injection amount of anticoagulant, etc.), alarm monitoring (venous pressure, dialyzer 4 inlet pressure, dialysate pressure, TMP (transmembrane pressure difference) and other pressure alarm points, as well as a decrease in UFR Monitoring, etc.), blood flow (drive speed of blood pump 5), clearance of dialyzer 4 detected by dialysis amount monitor, and the like. In addition, as the treatment condition or operation setting registered by the other registration means 14, the amount of blood returned in the blood return step (the amount of blood returned after the blood purification treatment, which is determined by the rotation speed of the blood pump, etc.) And the like.

  In particular, the registration unit 14 according to the present embodiment registers a treatment condition or an operation setting corresponding to a membrane area of a blood purifier (dialyzer 4 or the like) used in a blood purification treatment. In other words, a large-capacity blood purifier tends to increase the amount of priming cleaning and the priming cleaning time as well as the normal blood purifier. The parameter whose time has been increased is registered.

  When using a blood purifier having a coating agent applied to a purification membrane such as a hollow fiber membrane (glycerin for protecting the purification membrane or PVP as a hydrophilizing agent), the coating agent does not remain during use. By doing so, the parameters that increase the amount of priming and the time for cleaning are registered. Furthermore, since a large-volume blood purifier tends to increase the amount of anticoagulant used, as a treatment condition or operation setting to be registered, a parameter that increases the amount of anticoagulant used than usual is used. be registered.

  Here, the UFR refers to a water removal rate in ultrafiltration, and is composed of a parameter that quantifies how much water passes through depending on time and pressure. Thereby, the water permeability of the dialyzer 4 can be represented, and the higher the UFR, the higher the water permeability. However, the blood purification device (dialysis device) measures the UFR immediately after the treatment is started in order to detect the clogging of the purification membrane (hollow fiber membrane) of the dialyzer 4, and detects that the UFR has decreased by a predetermined value therefrom. Monitoring method (UFR monitoring). Most large-volume blood purifiers (such as the dialyzer 4 having a large membrane area) are often used for patients who want to increase the removal effect, and have a high UFR. When using such a large-volume blood purifier having a high UFR, if the UFR is measured immediately after the start of treatment in order to monitor the UFR, the UFR may be too high to make the measurement difficult. Therefore, when a large-volume blood purifier is used, the treatment condition or operation setting registered by the registration unit 14 is changed to another appropriate monitoring method without performing the UFR monitoring.

  Furthermore, the registration unit 14 according to the present embodiment is configured to limit or recommend the registered treatment conditions or operation settings according to the performance, properties, or functions of the blood purifier. That is, since the blood purifier registered by the registration unit 14 and the treatment condition or operation setting according to the blood purifier are preferably appropriate parameters according to the performance, properties or functions of the blood purifier, for example, the display unit At the time of registration by M, the recommended treatment condition or operation setting is displayed and selectively registered, or the treatment condition or operation setting is restricted so that the restricted parameter cannot be input. Has become.

Next, a registration method and a setting method of the blood purifier according to the present embodiment will be described.
First, as an initial screen of the display means M, as shown in FIG. 4, various displays of a preparation stage of the blood purification treatment are displayed, and operation buttons Ma and Mb for input are displayed. When the operator touches the operation button Mb in order to perform registration by the registration means 14, a small screen shown in FIG. 5 is displayed. When the operator touches the operation button Mc in the small screen, another small screen is displayed as shown in FIG. 6, and by touching the operation button Md of the small screen, a selection as shown in FIG. Is displayed.

  When the user touches the operation button Me on the display "Dializer information" (see FIG. 8) on the display screen for such selection, a registration screen is displayed as shown in FIG. 9, so that the information for specifying the blood purifier is displayed. Items such as (product name, etc.), their type (hollow fiber membrane type, laminated type, etc.), and treatment conditions or operating conditions (priming time and washing time in this embodiment) are displayed, respectively. When the user touches the display (for example, the predetermined display Mf), an input screen that allows input as shown in FIG. 10 is displayed.

  On this input screen, it is possible to change a parameter relating to the predetermined display Mf. In this case, when using the blood purifier set as the “dialyzer 1”, the amount of the cleaning liquid used in the priming process ( Dialysate volume) can be set. That is, the treatment condition or the operation condition corresponding to the blood purifier registered as "Dializer 1" can be linked and registered. Of course, other blood purifiers can be registered by touching a predetermined display indicating “name” on the screen of FIG. 9.

  On the other hand, before the blood purification treatment is performed, when the initial screen shown in FIG. 4 is displayed, the blood purifier (the dialyzer 4 and the like) and the blood circuit 3 are attached to the apparatus main body 8. Then, for example, when the input operation is performed by touching the operation button Ma, a new small screen is displayed as shown in FIG. 11. Therefore, when the blood purifier to be used is not selected, the input button Mg in the small screen is touched. Upon input, priming is started based on preset treatment conditions or operation settings (treatment conditions or operation settings transmitted from the central monitoring device 2).

  However, when the operation button Mh is touched on the small screen shown in FIG. 11, a new small screen is displayed as shown in FIG. 12, and when the operation button Mi on the small screen is touched, as shown in FIG. A small screen for selection is displayed. On this small screen, a plurality of blood purifier names (product names, etc.) registered in advance by the registration means 14 are displayed, and when the blood purifier to be used is touched, the change means 15 causes the registration means 14 to change the name. It will be changed to the registered treatment condition or operating condition. In this case, a dialyzer named “FDX-150GW” was selected as the blood purifier to be used, and the blood purifier was selected on condition that the operation button Mg was touched on the display screen shown in FIG. Priming based on treatment conditions or operation settings according to the blood purifier is performed.

  According to the present embodiment, the registration means 14 capable of registering in advance the treatment conditions or operation settings according to the performance, properties or functions of the blood purifier, and the blood purifier (dialyzer 4 etc.) used in the blood purification treatment. And a change unit 15 that can change the treatment condition or operation setting to the treatment condition or operation setting registered by the registration unit 14, so that a blood purifier that requires a specific treatment condition or operation setting is used. However, the operability can be improved.

  The treatment condition or operation setting registered by the registration unit 14 is a priming cleaning amount or cleaning time or a priming method according to the blood purifier, so that a blood purification device for which a specific treatment condition or operation setting is required. , The amount or time of priming, or the priming method can be appropriately set. Furthermore, since the registration unit 14 registers the treatment condition or operation setting according to the membrane area of the blood purifier used in the blood purification treatment, a blood purifier that requires a specific treatment condition or operation setting depending on the membrane area is used. However, even when the operation is performed, the operability can be improved. Still further, the registration unit 14 limits or recommends the treatment condition or operation setting to be registered according to the performance, property or function of the blood purifier, thereby facilitating the registration operation by the registration unit 14. And erroneous settings can be suppressed.
