Caution ● Remove static electricity, using an earth-band when a board is maintained or changed. ● Do not touch any point other than the mentioned point by a tester when a board is

maintained, connecting probes or IC clips of tester. It could be a cause of board breakdown, depending on the touched place.

● Do not touch any board, electric wiring or terminal except for a maintenance. ● Do not touch any electric wiring or terminal which is not isolated. ● Do not touch any board with wet hand. ● Pull out a power plug from an outlet when the harness is removed from a Terminal block. ● Use a tester which is “True RMS TYPE” to measure precise alternating current value.

amount of the A dialysate for 3 rounds continuously.

③ Take out the A dialysate (P3) concentration solution

electric scale.

Measure the B dialysate (P4) similarly.

Based on the measured value, calculate the coefficient by

Standard Standard 1mmHg or less/ 2 minutes 1mmHg or less/ 2 minutes

Required jig Pressure gauge, piping components, pean pincer x 2, syringe, stopwatch

Purpose Leak test in clamped state


Set the pressure gauge, piping components (with no water),

syringe to the clamp.

With bubbles, turn on the bubble detector operation switch

to clamp.

Pressurize with a syringe and fix the pressure gauge value

to 150mmHg with pean pincers.

fixation, so leave it for approximately 90 seconds.

The pressure gauge value after leaving for 90 seconds is

to be A.

The pressure gauge value after leaving for another 2

minutes is to be B.

Shut off the adjusting tool for leakage test with a forceps

as in the left figure.

Required jig Stopwatch, caliper square, calculator, pressure gauge, syringe (20mL), piping

components

Purpose Stroke: For syringe injection rate verification.

Overload: To verify whether the syringe is stopped at the specified pressure or not.


【Stroke test】

Syringe ratio of Maintenance 6 “Device calibration”

is to be 100%.

Move the pusher of heparin pump to the right end and

measure the position with the caliper square. “Distance A” Press the heparin pump flow display section and set the

HP injection speed to 9.9mL/hour.

Make sure the blood pump is running. (Without blood pump

revolution, the syringe pump does not work.)

Start up time measurement by a stopwatch simultaneously

with turning on the blood pump operation switch.

Memo

The heparin pump operates in conjunction with the blood pump.

Measurement with the actual injection amount is impossible due to individual difference of syringe.

Therefore, normality of the heparin pump injection

amount should be confirmed by obtaining the pusher

travel distance per 1 minute in the stroke test and

confirming the obtained distance is within the

standard range.

Turn OFF the heparin pump operation switch after operation

for 30 minutes then measure the pusher travel distance

with the caliper square.

“Distance B” Travel distance per 1 minute =

Calculate (distance A [mm]－Distance B[mm])÷ operation

time [min].

Confirm the travel distance per 1 minute is 0.494 to

0.546mm/min.

If out of the standard range, refer to BHTS**-003.

Caution

After the test, return the syringe ratio to the original value.

【Overload adjustment】

Remove the cover for the upper left face.

Set the syringe with the pressure gauge installed at the

end.

Turn ON the heparin pump operation switch.

Adjust the nut so that the “E63 syringe overload or injection completion” alarm is detected when long-pressing the heparin pump flow fast-forward switch

and adding pressure of approximately 0.086Mpa (500 to

800mmHg). (For the nut position, refer to BHSM**-003.)

Caution

Overload detection pressure fluctuates due to sliding resistance of the syringe gasket.

Ｏ．Rotating in the compressing direction of L spring

rises the overload detection pressure. Rotating in the

extending direction lowers the pressure.

memo

Overload detection value changes approximately 0.022Mpa (160mmHg) per one turn of nut. (Pressure

change is the reference value when the Nipro 20mL is

used.)

* No need to remove the heparin pump for adjustment.

Standard Standard P3 actual flow: 13.3 to 15.3g (per 1 round) P4 actual flow：17.5 to 18.5g (per 1 round)P3 actual flow: 13.3 to 15.3g (per 1 round) P4 actual flow：17.5 to 18.5g (per 1 round)

Required jig Electric scale, container (approximately 2L)

Purpose Measure discharge volume and

calculate the coefficient value, to infuse precise solution.



To uniform the suction amount of the concentrate solution,

rotate the P3 and P4 spindle to the position shown in the

figure.

Face up the white circle part.

<Configuration of concentration solution pump>

Upper one is P4.

Lower one is P3.

Set the chamber volume of Maintenance 5 “Concentrate calibration” to 500mL for both A and B.

Set the coefficient “P3 flow” and “p4 flow” of Maintenance 6 “Device calibration” to the following values.

① Set the container containing water to the electric

scale and perform zero reset.

② Put the A dialysate (P3) concentration solution

connector in the container and measure the suction

amount of the A dialysate for 3 rounds continuously.

③ Take out the A dialysate (P3) concentration solution

connector from the container and read the value on the

electric scale.

Measure the B dialysate (P4) similarly.



P3 = (measured value ÷3)÷P3 theoretical value

P3 = (measured value ÷４)÷P3 theoretical value

Input the obtained coefficient to Maintenance 6 “Device calibration” and measure for 3 rounds each suction amount

again.



Measured value ÷3 = suction amount per 1 round

If the calculation result is within the standard range,

regarded as passed.

If out of standard range, perform measurement again.

Return the chamber volume of Maintenance 5 “Device calibration” to the original value.
