AK 95 HCEN9135 Rev. 10.2005
Ultrasonic detector placed at the venous drip chamber. The
detector has a two channel structure and the function of the
detector is tested at the function test made by the
microcomputers.
Diameter 22 mm
Bubbles larger than 1 µl will be trapped by the drip chamber.
An alarm will be issued if the blood level falls below the
middle of the air detector.
0 to 10 ml/h (±1 ml/5h or ±5%) The accuracy is based on
tests with 20 ml and 30 ml syringes
Syringes shall comply with ISO 7886-2. Upon delivery, the
machine is set for a 20 ml Terumo syringe. Syringes of other
volumes and brands can be set.
Heparinization stops before end of treatment 0.00 to
9.59 h
Maximum 400 mmHg
0 to 999.9 ml
During treatment: maximum 770 ml/min
During disinfection and rinse/drain: a maximum flow rate of
800 ml/min is required.
0.12 MPa (1.2 bar)
0.6 MPa (6 bar)
+5 to +30 ºC
Diameter 8 mm
Inlet water quality must comply with local regulations and if
no such regulation is available follow ISO 13959.
Level for conductivity shall not exceed 0.1 mS/cm.
It is possible to use water with higher conductivity if it
consists mainly of sodium salts. This may however affect the
accuracy of the fluid composition.
The drain tube outlet must be placed between floor level and
maximum 1.2 m above the outlet connection from the fluid
monitor. An air gap to atmospheric pressure must always be
arranged at the tube outlet.
<10 m
±500 mmHg, (±10 mmHg or ±5 %, whichever is largest)
Increasing: +150 mmHg, ±20 mmHg
Decreasing: +99 mmHg, ±20 mmHg
