At the time of 206), the driving of the clamp motor 93 is controlled so that the dialysate flows from the tube 15 to the tube 17, and the predetermined clamp 570 is opened. Then, the drive of the air pump / leak valve 89 is controlled to bring the pressure in the bag storage portion 52 into a pressurized state. As a result, the pressure in the heating dialysate bag 5 rises, and the heated dialysate in the heating dialysate bag 5 passes through the tubes 16, 15, 17, the transfer tube 18 and the catheter tube 19. Then, it is injected into the peritoneum of the patient 300.

When injecting the dialysate into the patient 300,
For example, the flow rate of dialysate can be controlled as follows. The total weight of the dialysate bag 5 for warming is detected by the unit 79 for each unit time, and the amount of dialysate outflow (= injection amount of dialysate) from the dialysate bag 5 for heating per unit time is detected from the reduction rate. Then, the pressure in the bag storage portion 52 is adjusted so that this outflow amount becomes equal to a preset set outflow amount. In this case, based on the detection value of the pressure sensor 91,
It is also possible to control the pressure in the bag storage portion 52 so as not to exceed a preset upper limit value.

As a result, the pressure in the dialysate bag 5 for heating is reduced, and the dialysate in each of the dialysate bags 4a to 4d passes through the tubes 11, 12, 14, 15 and 16 and the dialysate bag for heating. Introduced in 5. Also, if necessary, the dialysate in the dialysate bag 4e may be replaced by the tubes 11, 1
It is introduced into the dialysate bag 5 for warming through 3, 15 and 16.

When introducing the dialysate into the warming dialysate bag 5, the flow rate of the dialysate can be controlled as follows, for example. The dialysate bag 5 for heating by the scale 79
The total weight of the dialysate is detected every unit time, and the inflow rate of the dialysate into the warming dialysate bag 5 per unit time is calculated from the rate of increase so that this inflow rate becomes equal to the preset inflow rate. Then, the pressure in the bag storage portion 52 is adjusted. In this case, based on the detection value of the pressure sensor 91, the pressure in the bag storage portion 52 can be controlled so as not to exceed a preset lower limit value. Further, when the inflow of the dialysate into the warming dialysate bag 5 reaches a steady state, the pressure in the bag storage portion 52 is kept constant based on the detection value of the pressure sensor 91 as described above. You can also adjust it to Such pressure adjustment is performed by opening and closing a leak valve, for example.

When the total weight of the warming dialysate bag 5 (dialysate outflow rate) detected by the balance 79 is the preset one-time injection rate (target injection rate) of dialysate, It is determined whether or not the weight (set weight) has been reached, and when it reaches this, the drive of the clamp motor 93 is controlled, all clamps 570 are closed, the air pump is stopped, and the leak valve is opened. As a result, the bag storage unit 5
The inside of 2 returns to atmospheric pressure.

Then, by controlling the driving of the heater 78,
The dialysate in the warming dialysate bag 5 is heated to a preset temperature. At this time, as described above, based on the temperature information detected by the temperature sensors 82 and 83,
The heater control circuit 76 controls the drive of the heater 78 so that the temperature of the dialysate in the warming dialysate bag 5 is maintained near the preset temperature (ON / OFF control or output of the heater 78 ( Calorific value) is controlled).

When introducing the drainage into the reservoir bag 8, the flow rate of the drainage can be controlled as follows, for example. The total weight of the reservoir bag 8 is detected every unit time by the scale 79, and the drainage inflow amount into the reservoir bag 8 per unit time is obtained from the increase rate, and this inflow amount is equal to a preset set inflow amount. The pressure in the bag storage portion 52 is adjusted so that In this case, based on the detection value of the pressure sensor 91, the pressure in the bag storage portion 52 can be controlled so as not to exceed a preset lower limit value. When the drainage of the drainage into the reservoir bag 8 reaches a steady state, the pressure in the bag storage portion 52 is adjusted to be constant based on the detection value of the pressure sensor 91 as described above. You can also Such pressure adjustment is performed by opening and closing a leak valve, for example.

As a result, the inside of the bag storage portion 52 returns to atmospheric pressure.

Next, the driving of the clamp motor 93 is controlled so that the drainage flows from the tube 21 to the tube 23, and the predetermined clamp 570 is opened. Then, the drive of the air pump / leak valve 89 is controlled to bring the pressure in the bag storage portion 52 into a pressurized state. As a result, the pressure in the reservoir bag 8 rises, and the drainage liquid in the reservoir bag 8 becomes

The pressure in the bag storage portion 52 is adjusted so that In this case, based on the detection value of the pressure sensor 91, the pressure in the bag storage portion 52 can be controlled so as not to exceed the preset upper limit value. Further, when the drainage of the drainage from the reservoir bag 8 reaches a steady state, as described above, based on the detection value of the pressure sensor 91, the bag storage portion 52.
It can also be adjusted to keep the pressure inside constant.
Such pressure adjustment is performed by opening and closing a leak valve, for example.

Whether the total weight of the reservoir bag 8 detected by the scale 79 has reached a weight corresponding to a preset residual liquid amount (for example, the residual liquid amount in the reservoir bag 8 is 0). If it is reached, the drive of the clamp motor 93 is controlled, all the clamps 570 are closed, the air pump is stopped, and the leak valve is opened. As a result, the inside of the bag storage portion 52 returns to atmospheric pressure.

Further, the introduction of the drainage into the reservoir bag 8 and the transfer to the drainage bag are repeated until the drainage of the drainage from the patient 300 is stopped (a predetermined weight change amount).

The content of the alarm corresponding to the error, the number of cycles up to the present, and the type A / type B are displayed. The display unit 69 constitutes an informing means for informing the information regarding the liquid transfer.

Here, in the present embodiment, the normality / abnormality of the liquid feeding is judged by comparing the liquid feeding amount detected by the scale 79 with the threshold value. That is, when the liquid delivery amount detected by the balance 79 is less than or equal to the threshold value, it is determined that an abnormal situation has occurred, and the error processing is performed.

[0200] Examples of the liquid supply amount include the liquid injection amount, the liquid discharge amount, the initial liquid discharge amount, the final liquid injection amount, the initial liquid injection amount, and the Tidal amount.

In the error state, the start switch 5
When 51 is turned on, treatment is restarted. In this case, the treatment continues from the step that was being performed immediately before it was stopped.

Further, when the initial drainage amount is set to the reference value or less, in this embodiment, when the initial drainage amount is set to the minimum unit of the set value (set value of the liquid feed amount) (When the minimum unit of the set value of liquid transfer is set to 50 mL (for adults), when the initial drainage is set to 50 mL, the minimum unit of set value of liquid transfer is 10 mL (for children for)
When the initial drainage amount is set to 10 mL), error processing (lighting of the alarm lamp 556, alarm display on the display unit 69, and
It is prohibited to close all the clamps 570 to stop the liquid transfer).

As a result, in this peritoneal dialysis apparatus 1, even when the initial drainage amount is unknown, particularly when the initial drainage amount is small and the initial drainage amount is unknown, the initial drainage amount is set to the set value. By setting it to the minimum unit, it is possible to smoothly exchange the dialysate, that is, shift from the initial drainage to the injection.

Further, in the peritoneal dialysis apparatus 1, as described above, the power failure detection circuit 102 detects a power failure.

When a power failure occurs, the voltage applied from the power transformer 97 to the power failure detection circuit 102 becomes 0, and the signal from the power failure detection circuit 102 is transmitted to the control means 71 and the safety circuit 10.
Input to 3 respectively. In this case, the control means 71
A predetermined switch (not shown) is switched so that power is supplied from the battery 101, and power failure processing is executed (S110).

In the power failure process, the safety circuit 103 causes the clamp control circuit 92, the pump control circuit 88, and the heater control circuit 76 to close all the clamps 570 to return the inside of the bag storage portion 52 to the atmospheric pressure state, and the heater. Stop 78. Then, it stands by in this state.

A preset waiting time (for example, 1
If it recovers from the power failure within about 30 minutes), the treatment is restarted. In this case, the treatment continues from the step that was being performed immediately before it was stopped.

If the power is out after the preset standby time has elapsed, the above-mentioned error processing is performed (S111).

When the stop switch 553 is turned on for 5 seconds or more in the error state or the temporary stop state described above, the treatment is forcibly ended (stopped), and the display section 69 displays "CHIRYU CHUCHU".

As described above, every time the report switch 552 is turned on, the initial drainage amount, the total water removal amount,
The final liquid injection amount and the preselected items are sequentially displayed.

As described above, when the stop switch 553 is turned on, "Clamping Dough" is displayed and all the clamps 570 of the clamp portion 57 are closed. Then, when this clamp operation is completed,
"Cassette is lost" is displayed. Power switch 6
When 3 is turned off, the power is turned off (S10
1).

As described above, according to the peritoneal dialysis apparatus 1, since the peritoneal dialysis can be automatically performed from the start to the end, for example, the patient gets up while sleeping and switches the flow path. It does not take time and effort.

The total amount of liquid injected, the total amount of discharged liquid, the amount of redrained liquid, the average storage time, the amount of liquid injected for each cycle, the amount of discharged liquid for each cycle, the amount of water removed for each cycle, and the amount for each cycle. It is possible to display the preselected items of the storage time, remaining storage time and remaining dialysis time, initial drainage volume, total water removal volume, and final injection volume. It can be easily grasped. In this case, since display items can be selected, it is possible to prevent the display from being complicated and display only necessary items.

In addition, an automatic mode in which the dialysate remaining in the dialysate bag can be automatically transferred to the drainage bag after the dialysis is completed, and the dialysate remaining in the dialysate bag is drained. Since it can be set to a manual mode in which it is possible to manually select whether or not to transfer, the versatility is wide.

Further, since the re-drainage mode can be set, a higher therapeutic effect can be obtained. In addition, since the minimum unit of the set value of the liquid transfer amount can be changed, that is, 10 mL / 50 mL can be set, each dialysis condition can be finely set to an appropriate value, and thereby optimal treatment can be performed. You can

When an abnormality occurs, error processing is performed, and in the case of power failure, power failure processing is performed.
High safety.

Further, the injection of the dialysate into the patient 300 and the transfer of the liquid during the recovery of the drainage from the patient 300 are performed by pressurizing the atmosphere of the dialysate bag 5 for heating and the atmosphere of the reservoir bag 8, respectively. Since it is performed by reducing the pressure, it is not necessary to secure a head for obtaining liquid circulation, and the sleeping position (height) of the patient can be freely selected.

Further, since it is not necessary to secure a drop from the sleeping position of the patient in both the dialysate bag and the drainage bag, the device can be downsized, and the accident of accidentally tipping the device during sleep can be prevented. it can.

The peritoneal dialysis apparatus of the present invention has been described above based on the illustrated configuration example, but the present invention is not limited to this, and the configuration of each part may be any configuration having the same function. Can be replaced with one.

For example, in the present invention, the notification of the liquid transfer abnormality is
It may be configured to be performed by voice or a buzzer.

Further, in the present invention, the liquid feeding means is, for example,

As described above, according to the peritoneal dialysis device of the present invention, the display item can be selected,
The display can be prevented from becoming complicated, only necessary items can be displayed, and the operation is simplified.

[0224] Further, there are an automatic mode in which the dialysate remaining in the dialysate container is automatically transferred to the drainage recovery container after the dialysis is completed, and a manual mode in which whether or not the transfer is performed can be manually selected. Since it can be set to, it has wide versatility.

Further, since it is possible to set the re-drainage mode in which the residual liquid can be drained again after the last drainage is completed, a higher therapeutic effect can be obtained.

Further, since the minimum unit of the set value of the liquid delivery amount can be changed, the dialysis condition can be set to an appropriate value, and thus the optimum treatment can be performed.

Further, based on the liquid feed amount detected by the liquid feed amount detecting means, an abnormality in the liquid feed is detected, and the liquid feed is stopped,
Since it is configured to notify the liquid transfer abnormality, the safety is high.

Further, when the initial drainage amount is set to be equal to or less than the reference value, the initial drainage is configured so that the stop of the liquid feed and the notification of the liquid feed abnormality are prohibited. Even if the amount is small and unknown, the treatment can be smoothly performed.
