Description

  The present invention relates to a peritoneal perfusion device and a driving program thereof.

  Currently, it is said that there are about 230,000 chronic renal failure patients in Japan, of which 95-96% receive hemodialysis and the remaining 4-5% receive peritoneal dialysis. ing. Peritoneal dialysis therapy is a therapy in which a fixed amount of dialysate is injected into the abdominal cavity of a patient through a catheter, and this is stored for a certain period of time and then drained several times a day. When the peritoneal dialysis therapy is adopted, the patient himself can carry out at home or the like, so that the treatment cost and patient burden such as hospital visit are reduced as compared with hemodialysis therapy.

For peritoneal dialysis therapy, a drop system that transfers liquid between the liquid supply bag, the patient's abdominal cavity, and the drainage bag by using the falling weight of the liquid, and liquid transfer between the pumps is forcibly executed. There is a pump system to do. Among them, the dialysis therapy by the head method is effective for a patient who does not forcibly apply pressure to the patient, has a low risk, and does not want to put a burden on the body such as a child. In addition, in the therapy by the pump method, since the patient performs several dialysis treatments while sleeping, using the pressure from the pump, it can be performed even while the patient is sleeping, and the patient is less time-constrained. This method has become the mainstream of peritoneal dialysis (see, for example, Patent Documents 1 and 2).
Japanese Patent Laid-Open No. 10-174715 Japanese Patent Laid-Open No. 10-211276

  However, the pump-type therapy imposes a burden on the patient, and is not particularly suitable for a patient who does not want to place a burden such as a child. In addition, dialysis using a pump system usually ends the drainage process even when liquid remains in the abdominal cavity of the patient, and the drainage may not be performed. In addition, as described above, dialysis therapy using a head system is also used for patients who do not want to put a burden on children, and it is necessary to provide both pump and head systems in hospitals and the like. . In addition, it is necessary to prepare two types of disposable circuits corresponding to each infusion circuit. Furthermore, in hospitals and the like, it is necessary for a user (nurse or the like) who actually operates the apparatus to acquire knowledge about two methods regarding peritoneal dialysis.

As described above, conventionally, there are two methods for peritoneal dialysis. For this reason, it is necessary to prepare two kinds of devices for peritoneal dialysis, which increases the burden from the viewpoint of equipment preparation, and the user. It was necessary to acquire knowledge about the equipment usage procedures.
The present invention has been made to solve the above-described problems, and provides a peritoneal perfusion device having a configuration in which a head method and a pump method can be selected according to a patient's condition, treatment status, and the like, and a driving program thereof. With the goal.

In order to achieve the above object, the present invention adopts the following configuration.
The peritoneal perfusion apparatus according to the present invention can be connected to an infusion circuit composed of a fluid reservoir and a drainage reservoir, and a line connecting these and the patient's abdominal cavity, and the fluid in the infusion circuit The apparatus has a control unit that performs flow control of the fluid, and applies pressure to at least one of the liquid storage unit and the line based on a signal from the control unit to transfer the liquid in the infusion circuit. A flow path switching unit for switching the flow path of the liquid in the infusion circuit by executing a line opening / closing operation based on a signal from the control unit, and a liquid storage unit in the infusion circuit connected to the control unit And a flow signal receiving unit that receives a detection signal relating to a flow state of liquid between each of the drainage storage unit and the abdominal cavity of the patient, and an input signal from a user (patient or nurse), and the control unit receives the input signal. Input signal reception unit that outputs to And a fluid signal receiving portion having a head capable of fluid flow between the fluid reservoir and drainage reservoir of the infusion circuit and the abdominal cavity of the patient. When a detection signal is input to the unit, the control unit includes a first transfer unit that uses the pressure applied from the pressure transfer unit to transfer the liquid, and a second transfer unit that uses the drop to transfer the liquid. Is selected based on a user input signal to the input signal receiving unit.

  In addition, the drive program for the peritoneal perfusion device according to the present invention is a line of the infusion circuit with respect to the infusion circuit composed of the liquid storage unit and the drainage storage unit, and the line connecting these and the patient's abdominal cavity. A drive program for controlling the flow of liquid in the infusion circuit, the transfer step for executing the transfer of the liquid in the line of the infusion circuit, and the opening and closing operation of the line in the infusion circuit, A flow path switching step for switching the flow path, a flow signal reception step for receiving a detection signal relating to the flow state of the liquid in the line of the infusion circuit, and an input signal reception step for receiving an input signal from the user. In addition, there is a drop that allows fluid to flow between each of the fluid reservoir and drainage reservoir in the infusion circuit and the abdominal cavity of the patient, and is detected at the fluid signal reception step. When it is confirmed that the signal has been received, a first transfer means for applying a pressure to the liquid in the line of the infusion circuit to cause the liquid to flow, and a second transfer means for causing the liquid to flow using a drop are provided. And selecting based on the input signal in the input signal receiving step.

  As described above, the peritoneal perfusion device according to the present invention has a configuration in which the flow signal receiving unit is connected to the control unit, and a drop that allows fluid flow between the infusion circuit and the patient's abdominal cavity is provided. And when the detection signal is input to the flow signal receiving unit, the control unit includes a first transfer unit that performs transfer of the liquid using the pressurizing force by the pressurization transfer unit, and a liquid storage unit. The second transfer means for transferring the liquid using the drop between the drainage reservoir and the abdominal cavity of the patient is selected based on the input signal from the user. In the peritoneal perfusion apparatus according to the present invention, when the second transfer means is executed, it is possible to monitor the amount of liquid injected and drained into the abdominal cavity of the patient with the detection signal input to the flow signal receiving unit. It is possible.

  As described above, conventionally, a device that performs perfusion processing such as dialysis using a head method and a device that performs perfusion processing such as dialysis using a pump method are completely separate and independent. For this reason, conventionally, it has been difficult to use the head method and the pump method according to the patient's condition and the situation at that time. Further, in medical institutions and the like, it is necessary for an operator who performs perfusion processing to be familiar with work procedures and the like for both the head method and the pump method, which makes it difficult to learn the operation.

  On the other hand, in the peritoneal perfusion device according to the present invention, the first transfer means (corresponding to the pump system) is provided on the condition that the detection of the input of the detection signal is made in the flow signal receiving unit. Since the second transfer means (corresponding to the head method) can be executed and the user can make the selection, one of the pump method and the head method is selectively used by one device. Perfusion treatment can be performed. For this reason, the peritoneal perfusion apparatus according to the present invention is superior from the above-mentioned conventional in terms of cost and work. For example, when a child or the like who is unsuitable for execution of the pump-type perfusion process is an object to be processed, the process can be executed only by the second transfer means using the drop method.

  Further, as described above, in the case of the perfusion treatment using the pump method, the drainage may be low. However, in the case of using the peritoneal perfusion device according to the present invention, the perfusion cycle is repeated a plurality of times ( The second transfer means can be applied only to the drainage in the final cycle of injection into the abdominal cavity, fluid storage in the abdominal cavity, and drainage from the abdominal cavity. If this type of drive is used, the patient will be sleeping while being treated by the pump method until the fluid is stored in the final cycle, and the head will be drained only when the fluid is drained in the final cycle. Can be drained with high efficiency. In addition, although the method of providing the drainage process by the drop method in the final cycle can be employed as described above, the drainage process by the drop method can be executed after the final cycle is completed. As described above, in the peritoneal perfusion apparatus according to the present invention, it is possible to set various usage forms, and it is possible to perform perfusion processing with high efficiency while minimizing the burden on the patient. .

  In addition, when the pump-type device and the head-type device exist independently from each other as in the prior art, the infusion circuit (usually, a disposable circuit is used) also corresponds to each. Although it was necessary to prepare and was disadvantageous in terms of cost, when using the peritoneal perfusion device according to the present invention, both the pump method and the head method are used by using the infusion circuit formed in the same standard. It can be implemented and has advantages when considering infusion circuit stock and the like.

Therefore, the peritoneal perfusion apparatus according to the present invention can select a head method and a pump method according to a patient's condition, treatment status, etc., and is advantageous from the viewpoint of cost, workability, and freedom of processing selection. .
In the peritoneal perfusion device according to the present invention, a weight measuring device for detecting the weight of the liquid in the liquid storage unit and the drainage storage unit can be connected to the flow signal reception unit, and the control unit is configured to receive the flow signal reception unit. A configuration is adopted in which a determination is made that the second transfer means can be selected by connecting the weight measuring device to the tank, and the change in the weight of the liquid in both reservoirs is accepted as the flow state of the liquid. You can also

In the peritoneal perfusion device, usually, the liquid is once transferred from the liquid storage bag to the warming bag, and the temperature of the liquid is adjusted and then supplied to the patient's abdominal cavity. It also includes a warming bag.
In the peritoneal perfusion device according to the present invention, the control unit injects liquid from the liquid storage unit into the patient's abdominal cavity, the process of holding the liquid in the abdominal cavity of the patient for a required time, and the drainage from the patient's abdominal cavity. The process of discharging the liquid to the storage unit is defined as one cycle, and the control for repeating the cycle a plurality of times is performed.

Moreover, in the peritoneal perfusion device according to the present invention, as described above, each of the components in the infusion circuit has an arrangement form having a drop that enables fluid flow therebetween, and the flow signal receiving unit In the case where the detection signal is received, a configuration in which the control unit adopts the second transfer unit for the discharge process in the final cycle among the plurality of cycles may be employed.
Further, in the peritoneal perfusion device according to the present invention, as described above, the control unit executes the liquid injection process and the liquid discharge process in a plurality of cycles using the first transfer means, and the final cycle ends. When there is a drop that allows the liquid to flow between each of the infusion circuits at the time, and the detection signal is input to the flow signal receiving unit, the second transfer means is used to drain the liquid. It is also possible to adopt a configuration in which the processing to be executed is executed.

Further, in the peritoneal perfusion device according to the present invention, when the control unit determines that the fluid flow is stagnant from the detection signal from the flow signal receiving unit when the second transfer means is being executed. From the viewpoint of further improving safety, it is desirable to adopt a configuration of issuing an alarm.
As described above, the drive program for the peritoneal perfusion device according to the present invention has a drop between each of the liquid storage part and the drainage storage part in the infusion circuit and the abdominal cavity of the patient, and fluid flow is possible by the drop. When the condition that the detection signal reception is confirmed in the flow signal reception step is satisfied, it is possible to select the second transfer means using the drop method, and the liquid is transferred by pressurization. The first transfer means and the second transfer means can be selected based on an input signal from the user. Therefore, the driving program for the peritoneal perfusion device according to the present invention can select the head method and the pump method according to the patient's condition and treatment status, etc., from the viewpoint of cost, workability, and freedom of processing selection. It is an advantage.

The best mode for carrying out the present invention will be described below with reference to the drawings. In addition, the form used in the following description is an example for easily explaining the configuration and operational effects of the present invention, and the present invention is not limited thereto, and is an essential part of the present invention.

Among these, the control part 40 is comprised from CPU, for example, based on the drive program previously stored in the data storage part 43, for driving the clamp part 30, the driver 44 which drives the cylinder 22, and the heater 46 An instruction signal is output. Further, a signal line is connected to the control unit 40 to the encoder 23 mounted on the cylinder 22 so that position information regarding the rod stroke of the cylinder 22 is input.

The input unit 41 is a part that receives input from the user. The display unit 42 is made of, for example, a liquid crystal panel and displays various types of information when the apparatus is driven, information related to driving condition input before driving, and the like. The display unit 42 can also display an alarm when an abnormality occurs.
The data storage unit 43 stores in advance control conditions necessary for the control unit 40 to execute device drive control. The control unit 40 takes out information from the data storage unit 43 when driving the device, Alternatively, the data input from the input unit 41 is stored in the data storage unit 43.

  An essential feature of the peritoneal perfusion device 1b according to the present embodiment is a configuration in which a measurement signal receiving unit 45 is connected to the control unit 40. The weighing signal receiving unit 45 is a part that receives input of weight signals from weight measuring devices (hereinafter referred to as “weighing devices”) 51 and 52 (see FIG. 2), which will be described later. The signal relating to is digitized and output to the control unit 40. In addition, information about whether or not the connection between the weighing instruments 51 and 52 is achieved is output from the weighing signal receiving unit 45 to the control unit 40.

  The heater 46 is for heating the internal liquid of the heating bag 12 in the disposable circuit 1a. For example, the heater 46 is composed of an electric heating body such as a ceramic heater, and has a configuration for feeding back temperature information to the control unit 40. Have.

Each of the clamps 31 to 36 in the clamp unit 30 is configured to be independently driven based on an instruction signal from the control unit 40.
(Installation of measuring instruments 51 and 52)
The peritoneal perfusion system 1 according to the present embodiment is based on the above configuration, but the configuration described below can be selectively added. A configuration that can be added will be described with reference to FIG.

  As shown in FIG. 2, weight measuring devices (hereinafter referred to as “meters”) 51 and 52 can be selectively added to the peritoneal perfusion system 1 according to the present embodiment. ing. The two measuring instruments 51 can be laid under the heating bag 12 and are used to measure the weight of the dialysate entering and exiting the heating bag 12. On the other hand, the measuring device 52 is laid under the drainage bag 13 and used to measure the weight of the fluid discharged from the abdominal cavity of the patient.

  Signal lines are extended from the measuring instruments 51 and 52, respectively, and both are connected to the measuring signal receiving unit 45 in the peritoneal perfusion device 1b. For example, a jack-type connector connection method is used for connection between the signal lines of the measuring instruments 51 and 52 and the measuring signal receiving unit 45, and each measuring instrument 51 and 52 connects to the measuring signal receiving unit 45. Weighing signal Sig. 1, Sig. 2 is transmitted. Further, when the signal lines from the measuring instruments 51 and 52 are connected to the weighing signal receiving unit 45, it is recognized that they are connected, and signal line connection information is sent to the control unit 40.

In addition, as shown in FIG. 2, in the peritoneal perfusion system 1 according to the present embodiment, there is a drop ΔH between the heating bag 12 and the drainage bag 13 when laying at least the measuring devices 51 and 52. Furthermore, the arrangement of these bags 12 and 13 is such that the abdominal cavity of the patient is located between the two bags in the height direction.
In this embodiment, the measuring instruments 51 and 52 are laid so that the liquid weight of the warming bag 12 and the drainage bag 13 can be measured. You may decide to lay under the liquid supply bag 11 instead of under. However, in this case, since the change state differs from the change in the liquid weight when laid under the heating bag 12, the data relating to the drive stored in the data storage unit 43 of the peritoneal perfusion device 1b in advance. Must be adapted.
(Drive of peritoneal perfusion system 1)
The drive form of the peritoneal perfusion system 1 having the above configuration will be described with reference to FIGS.

1. Main Driving Form As shown in FIG. 3, in the peritoneal perfusion system 1, a priming process is executed (step S1). The priming process is executed, for example, by the driver 44 receiving an instruction signal from the control unit 40 driving the cylinder and driving the clamp unit 30 based on the signal from the control unit 40. Since this step S1 is the same as the perfusion process by the conventional pump method, detailed description is abbreviate | omitted.

  Next, the control unit 40 confirms whether or not the signal lines from the weighing instruments 51 and 52 are connected to the weighing signal receiving unit 45 (step S2). As described above, this is performed by checking whether or not the signal line connector is connected to the measurement signal receiving unit 45. In step 2, when the control unit 40 determines that the weighing instruments 51 and 52 are not connected (step S2: N), the control unit 40 displays “pump method processing” on the display unit 42. Is displayed (step S3), and a confirmation input from a user such as a patient or a nurse is requested (step S4). When the user inputs “do not execute” from the input unit 41 in response to the confirmation input request from the control unit 40 (step S4: N), the control unit 40 displays the measuring instrument on the display unit 42. A display requesting connection confirmation of 51 and 52 is displayed (step S5), and the process returns to step S2 to execute the process.

When the user inputs “confirmation OK” in step S4 (step S4: Y), the control unit 40 executes a peritoneal dialysis process using a pump system (step S6). The peritoneal dialysis treatment using the pump system will be described later.
As shown in FIG. 3, when the control unit 40 confirms the connection of the signal lines from the measuring instruments 51 and 52 in step S <b> 2 (step S <b> 2: Y), the control unit 40 executes the process using the “drop method” on the display unit 42. The confirmation request “is it?” Is executed (step S7). In this process, the control unit 40 displays the message on the display unit 42 and waits for a user's selection input from the input unit 41. When the user inputs that the head method is not adopted (step S7: N), the control unit 40 executes step S3.

  In step S7, when the user inputs that the process using the head method is to be executed (step S7: Y), the control unit 40 gives the user “a plurality of pump methods and head methods”. A confirmation request is made as to whether or not to use both in the dialysis cycle (step S8). In response to the confirmation request in step S8 from the control unit 40, when the user inputs that the combination is not to be used (step S8: N), the control unit 40 causes the display unit 42 to perform a “drop method” process. A confirmation message "Do you want to execute" is displayed (step S9). When the user inputs that the head method is not executed in response to the confirmation request (Step S10: N), the control unit 40 displays a message requesting reselection of the execution method. 42 is displayed (step S11), and the process returns to step S8 to continue the process.

On the other hand, when the user inputs that the head method is selected in step S10 (step S10: Y), the control unit 40 executes peritoneal dialysis processing using the head method (step S12). In addition, when performing this process, as above-mentioned, arrangement | positioning of the measuring instruments 51 and 52 and the connection of a signal wire | line are confirmed.
The peritoneal dialysis treatment using the drop method will be described later.

  In step S8, when the user selects “Use both pump method and head method” (step S8: Y), the control unit 40 indicates that the display unit 42 executes both methods. A confirmation message is displayed (step S13). When the user selects from the input unit 41 that the two methods are to be used together (step S14: Y), the control unit 40 executes a dialysis process using both the pump method and the head method ( Step S15).

In step S14, when the user does not select the execution of the dialysis process using the two methods (step S14: N), the control unit 40 causes the display unit 42 to display a request for re-selecting the execution method of the process. (Step S16), returning to Step S8, the drive program is executed.
In the peritoneal perfusion system 1, the control unit 40 causes the process from step S1 to be re-executed by turning on a reset switch (not shown) before the dialysis process is started. Is possible.

2. Dialysis treatment using pump system (step S6)
In the peritoneal perfusion system 1, when the signal line from the measuring instruments 51 and 52 is not connected (step S2: N), or the signal line is connected but the user selects not to execute the drop method. If this is the case (step S7: N), a dialysis process by a pump method is performed on the patient. The dialysis process by a pump system is demonstrated using FIG.

  As shown in FIG. 4, in the dialysis process using the pump system, first, a counter (not shown in FIG. 1 and the like) built in the control unit 40 is reset (step S21). Next, the required amount from the liquid supply bag 11 to the warming bag 12 by the opening / closing operation of each clamp 31, 32, 36 of the clamp unit 30 and the pump function by driving the diaphragm 15 c in the cassette unit 15 by driving the cylinder 22. (For example, 2 L) of dialysate is transferred. When the liquid transfer from the liquid supply bag 11 to the heating bag 12 is started, the power of the heater 46 is turned on from the control unit 40, and the temperature adjustment of the heating bag 12 is started (step S23). .

  After the required amount of dialysate is stored in the warming bag 12, the controller 40 closes all the clamps 31 to 36 and keeps the state until the liquid temperature reaches a predetermined temperature from the temperature information from the heater 46. maintain. Then, based on the feedback of temperature information from the heater 46, after the dialysate in the warming bag 12 reaches the required temperature, the control unit 40 opens and closes the clamps 32, 35, 36 of the clamp unit 30 and The driving of the cylinder 22 is executed, and the dialysate is transferred from the heating bag 12 to the abdominal cavity of the patient (step S24).

  When the transfer of the dialysate from the heating bag 12 to the abdominal cavity of the patient is completed, the control unit 40 sets the built-in counter to (k + 1) (step S25). The control unit 40 also resets a built-in timer (not shown in FIG. 1 and the like) with the execution of step S25 (step S26). Then, the controller 40 once transfers the dialysate from the liquid supply bag 11 to the warming bag 12 using the same method as described above after the clamps 31 to 36 are fully closed (step S27). ). At this time, the heater 46 of the peritoneal perfusion apparatus 1b is turned on to warm the dialysate (step S28). After a required amount of dialysate is transferred to the warming bag 12, the control unit 40 fully closes the clamps 31 to 36 of the clamp unit 30.

  On the other hand, the dialysate in the patient's abdominal cavity is stored until the count time t of the timer reaches time T (step S29: N), and when the count time t of the timer reaches time T, the control unit 40 The liquid is transferred from the abdominal cavity of the patient to the drainage bag 13 by the opening / closing operation of the unit 30 and the driving of the cylinder 22 (step S30). In addition, in the liquid transferred to the drainage bag 13 at this time, in addition to the injected dialysate, wastes discharged from the patient's body, removed moisture, and the like are included.

Next, the control unit 40 checks whether or not the counter value is (n−1), that is, whether or not it corresponds to one time before the final cycle of the dialysis cycle that is executed a plurality of times (step S31). If the counter value has not reached (n−1), the control unit 40 returns to step S24 and executes the process.
When the counter value k reaches (n−1), the control unit 40 sets the counter value k to (n) (step S32), and resets the timer (step S33). In the final cycle of the plurality of cycles, the control unit 40 drives the clamp unit 30 and the cylinder 22 so as to transfer the dialysate from the heating bag 12 to the abdominal cavity of the patient (step S34). After the elapsed time t of the timer reaches time T (step S35: Y), the control unit 40 transfers the liquid from the patient's abdominal cavity to the drainage bag 13 (step S36), and then ends the process. To do.

3.2 Dialysis treatment by combined use of two methods (step S15)
In the peritoneal perfusion system 1 according to the present embodiment, signal lines from the measuring instruments 51 and 52 are connected to the measurement signal receiving unit 45 so that the measurement signal Sig. 51, Sig. 52 is accepted (step S2: Y), and the user inputs from the input unit 41 that the dialysis process using the combination of the pump method and the head method is selected (step S8: Under the condition of Y), a dialysis process using the two systems is executed (step S15). Hereinafter, this processing method will be described with reference to FIG. In the dialysis process according to the present method, the process until the counter value k reaches (n-1) is the same as that of the pump system, and therefore a description thereof is omitted.

  As shown in FIG. 5, in the dialysis treatment using the two systems, when the counter value k becomes (n-1) in step S51 (step S51: Y), the counter value t is set to (n The timer is reset (step S53), and the dialysate is injected into the abdominal cavity of the patient using the pump system (step S54). When the time t measured by the timer reaches the time T (step S55: Y), the drainage process is executed from the abdominal cavity of the patient to the drainage bag 13 by the drop method (step S56).

  As described above, in the peritoneal perfusion system 1 according to the present embodiment, when the dialysis treatment using the two methods is performed, the liquid transfer means using the drop method is applied to the drainage treatment in the final cycle among a plurality of dialysis cycles. It has a configuration. In the case of using the peritoneal perfusion system 1 according to the present embodiment, the peritoneal perfusion device 1b executes liquid transfer and the like based on the drive program, so that the patient can be in the final cycle even in the state of sleeping. Can be drained. And compared with the case where all the cycles are performed only by a pump type, when the dialysis process which uses 2 systems together is selected, the liquid which remains in the abdominal cavity of a patient after completion | finish of a dialysis process can be reduced. The operation for each step of such driving is shown in the following table.

また、本実施の形態では、２方式併用による透析処理を実行する場合、複数の透析サイクルの内の最終サイクルにおいて、排液処理に落差方式を採用することとするが、上記ポンプ方式による複数の透析サイクルを終了後に、さらに落差方式による排液処理だけを延長して実行することとしてもよい。このような駆動のステップ毎の動作を次表に示す。

In the present embodiment, when the dialysis treatment using the two methods is performed, a drop method is adopted for the drainage treatment in the final cycle of the plurality of dialysis cycles.

Next, the control unit 40 opens the clamp 36 (step S63), closes the clamp 32 (step S64), and opens the clamp 31 (step S65). Then, the control unit 40 instructs the driver 44 to drive the cylinder 22 while maintaining the open / closed states of the clamps 31 to 36 (step S66). When performing such driving, the dialysate in the liquid supply bag 11 is transferred to the inside of the cassette unit 15 through the line 10a and the line 10f.

  After the required amount of dialysate is drawn into the internal space of the cassette unit 15, the control unit 40 closes the clamp 31 (step S67) and opens the clamp 32 (step S68). And the control part 40 drives the cylinder 22 in the state which maintained the said opening-and-closing state of the clamps 31, 32, and 36 (step S69), and assigns (j + 1) to the counter value j (step S70). The dialysate drawn into the internal space of the cassette unit 15 by the drive of the clamp unit 30 and the cylinder 22 is transferred to the warming bag 12 through the line 10f and the line 10b.

The control unit 40 repeats the above series of operations until the counter value j reaches (m) (step S71: N). At the time point when the counter value j = m (step S71: Y), the control unit 40 The clamp 32 and the clamp 36 are closed (step S72), and the liquid transfer process from the liquid supply bag 11 to the heating bag 12 is completed.
The value m to which the counter value j increases is stored in advance in the data storage unit 43 depending on the relationship between the internal volume of the cassette unit 15 and the amount of liquid transferred from the liquid supply bag 11 to the heating bag 12. For example, when the internal volume of the cassette unit 15 is 50 mL and the amount of transferred liquid is 2 L, the value m is set to 2 L / 50 mL = 40.

(2) Fluid transfer from the warming bag 12 to the patient's abdominal cavity As shown in FIG. 6 (b), when transferring dialysate from the warming bag 12 to the patient's abdominal cavity using the pump system, Similarly, the control unit 40 first resets the built-in counter (step S81), and closes the clamps 31, 33, and 34 (step S82). Next, the controller 40 opens the clamp 36 (step S83), closes the clamp 35 (step S84), and opens the clamp 32 (step S85). And the control part 40 instruct | indicates the drive of the cylinder 22 with respect to the driver 44, maintaining each open / close state of the said clamps 31-36 (step S86). By such driving, the dialysate heated to the required temperature in the warming bag 12 is transferred from the warming bag 12 to the inside of the cassette unit 15 through the line 10b and the line 10f.

  After a required amount of dialysate is drawn into the internal space of the cassette unit 15, the control unit 40 closes the clamp 32 (step S87) and opens the clamp 35 (step S88). And the control part 40 drives the cylinder 22 in the state which maintained the said opening-and-closing state of the clamps 31-36 (step S89), and assigns (j + 1) to the counter value j (step S90). By such driving of the clamp part 30 and the cylinder 22, the dialysate once drawn from the warming bag 12 to the internal space of the cassette part 15 is transferred to the abdominal cavity of the patient through the line 10f and the line 10e. The

The control unit 40 repeats the above series of operations until the counter value j reaches (m) (step S91: N). At the time point when the counter value j = m (step S91: Y), the control unit 40 The clamp 35 and the clamp 36 are closed (step S92), and the liquid transfer process from the heating bag 12 to the abdominal cavity of the patient is completed.
The value m to which the counter value j is increased is set to the same value as that at the time of transfer from the liquid supply bag 11 to the warming bag 12.

(3) Liquid transfer from the abdominal cavity of the patient to the drainage bag 13 As shown in FIG. 7, when transferring the dialysate from the abdominal cavity of the patient to the drainage bag 13 using the pump method, First, the control unit 40 resets the built-in counter (step S101), and closes the clamps 31, 32, and 34 (step S102). Next, the control unit 40 opens the clamp 36 (step S103), closes the clamp 33 (step S104), and opens the clamp 35 (step S105). Then, the control unit 40 instructs the driver 44 to drive the cylinder 22 while maintaining the open / closed states of the clamps 31 to 36 (step S106). By such driving, fluids stored in the abdominal cavity of the patient (such as dialysate and water and waste discharged from the patient) pass through the line 10e and the line 10f, and pass through the abdominal cavity of the patient to the internal space of the cassette unit 15. It is transferred to.

  After the required amount of dialysate is drawn into the internal space of the cassette unit 15, the control unit 40 closes the clamp 35 (step S107) and opens the clamp 33 (step S108). And the control part 40 drives the cylinder 22 in the state which maintained the said opening-and-closing state of the clamps 31-36 (step S109), and assigns (j + 1) to the counter value j (step S110). By such driving of the clamp part 30 and the cylinder 22, the dialysate once drawn from the patient's abdominal cavity to the internal space of the cassette part 15 is transferred to the drainage bag 13 through the line 10f and the line 10c. The

The control unit 40 repeats the above series of operations until the counter value j reaches (p) (step S111: N). At the time point when the counter value j = p (step S111: Y), the control unit 40 The clamp 33 and the clamp 36 are closed (step S112), and the liquid transfer process from the patient's abdominal cavity to the drainage bag 13 is completed.
The value p to which the counter value j is increased is set to a value larger than the value m at the time of liquid transfer from the liquid supply bag 11 to the warming bag 12 and at the time of liquid transfer from the warming bag 12 to the patient's abdominal cavity. Has been. That is, a value obtained by adding this value to the injection volume is set in advance in consideration of the amount of water removed from the patient.

5). Dialysis treatment using a head method (step S12)
In the peritoneal perfusion system 1 according to the present embodiment, the control is performed when an input signal indicating connection of a signal line from the measuring devices 51 and 52 to the measuring signal receiving unit 45 and selection of a head method from the user is received. The unit 40 uses a drop system for liquid transfer between the liquid supply bag 11, the warming bag 12, the drainage bag 13, and the patient's abdominal cavity. This will be described with reference to FIGS.

(1) Initial Confirmation Process in the Drop Method As shown in FIG. 8A, the control unit 40 first executes a drop method initial confirmation process when attempting to perform a liquid transfer process by the drop method. In this process, the control unit 40 fully closes the clamps 31 to 36 in the clamp unit 30 (step S121), maintains the state of the clamps 31 to 36, and the weighing signals Sig. 51, Sig. Whether or not 52 is received is checked (step S122). The control unit 40 receives the weighing signal Sig. 51, Sig. If it is confirmed that 52 can be normally received (step S122: Y), the initial confirmation process is terminated.

On the other hand, the control unit 40 determines that the weighing signal Sig. 51, Sig. If it is determined that one of the terminals 52 has not been received (step S122: N), the signal line connection confirmation request from the weighing instruments 51 and 52 is displayed on the display unit 42, and the process returns to step S122 to execute the processing. To do.
(2) Liquid transfer from the supply bag 11 to the heating bag 12 by the drop method In the peritoneal perfusion system 1, when the liquid transfer process by the drop method is selected, the control unit 40 opens and closes the clamp unit 30. The liquid is transferred by the control, and the liquid weight value from each of the measuring instruments 51 and 52 is used as a reference for the control.

  As shown in FIG. 8B, when the liquid transfer is to be performed from the liquid supply bag 11 to the warming bag 12 using the drop method, the control unit 40 opens the clamps 31 and 32 ( Step S131). At this time, the other clamps 33 to 36 in the clamp unit 30 are kept in the closed state. Thus, by performing the opening / closing operation | movement of the clamp part 30, the dialysate in the liquid supply bag 11 is transferred to the warming bag 12 by dead weight fall. The transferred dialysate is heated by turning on the heater 46 (step S132).

At the time of transferring the dialysate from the supply bag 11 to the heating bag 12, the controller 40 controls the Sig. 51 is monitored, and it is confirmed that the weight change ΔW _X in the measuring instrument 51 is not “0” (step S133).
In step S133, when the control unit 40 determines that ΔW _X = 0 (step S133: N), the display unit 42 is warned about occurrence of an abnormality, and an alarm device (not shown) is used. The user is notified of the occurrence of an abnormality (step S135). That is, even though the liquid transfer is executed using the drop method, ΔW _X = 0 indicates that the liquid is not transferred and the flow is stagnant. Indicates an abnormal situation.

On the other hand, if a change of ΔW _X is normally observed in step S133, the monitoring state is maintained until the weight W _X reaches the predetermined amount W ₁ (step S134: N), and W _X = At the time when W ₁ is reached (step S134: Y), the clamps 31 and 32 are closed (step S136), and the process is terminated.
(3) Liquid transfer from the heating bag 12 to the patient's abdominal cavity by the drop method As shown in FIG. 9A, in the peritoneal perfusion system 1 according to the present embodiment, the heating bag 12 using the drop method is transferred from the patient to the patient. First, the control unit 40 outputs an instruction to open the clamps 32 and 35 to the clamp unit 30 (step S141). Next, the control unit 40 sends the weighing signal Sig. 51 (step S142), and when the condition of change in liquid weight ΔW _X ≠ 0 in the measuring instrument 51 is satisfied (step S142: Y), clamp until W _X = 0 (step S143: N) 32 and 35 are kept open.

Similarly to the case of transferring the liquid from the liquid supply bag 11 to the warming bag 12, the control unit 40 determines that ΔW _X = 0 in step S142, that is, no change in the liquid weight is observed (step S142). S142: N), the display unit 42 is warned about the occurrence of an abnormality, and the user is notified of the occurrence of the abnormality by using an alarm device (not shown) (step S144).
When the control unit 40 determines that W _X = 0 in step S143 without detecting an abnormality in step S142, the control unit 40 outputs an instruction to close the clamps 32 and 35 to the clamp unit 30 (step S145). End the operation.

In this operation, the clamps 31, 33, 34, 36 other than the clamps 32, 35 are kept closed.
(4) Drainage process from the abdominal cavity of the patient to the drainage bag 13 by the drop method In the drainage process from the abdominal cavity of the patient to the drainage bag 13 by the drop system, the control unit 40 first clamps the clamp unit 30 with respect to the clamp unit 30. The opening instructions 33 and 35 are output (step S151). In the case of this liquid transfer operation, when the clamps 33 and 35 are in the open state, the control unit 40 sends the weighing signal Sig. 52 is monitored (step S152). In step S152, when the change in liquid weight ΔW _Y ≠ 0 in the measuring instrument 52 (step S152: Y), the control unit 40 clamps 33, 35 until the condition of the weighing weight W _Y = W ₂ is satisfied. Is kept open (step S153: N).

When the control unit 40 detects that W _Y = W ₂ in step S153, the control unit 40 outputs an instruction to close the clamps 33 and 35 to the clamp unit 30 (step S155). Here, the set liquid weight W ₂ may be different from the weight of the dialysate injected from the warming bag 12 into the patient's abdominal cavity, and is a waste product discharged from the patient's body. It is a weight value that contains water and moisture. This value is stored in the data storage unit 43 of the peritoneal perfusion apparatus 1b according to a prescription by a doctor or the like before performing the perfusion process.

In step S152, when the control unit 40 detects a change in liquid weight ΔW _Y = 0 (step S152: N), the weight change W during liquid transfer from the warming bag 12 to the abdominal cavity of the patient. _{As in} the case of _X = 0, the control unit 40 issues a warning regarding the occurrence of an abnormality on the display unit 42, and notifies the user of the occurrence of the abnormality using an alarm device (not shown) (step S154).
