BLOOD PUMP

Clean and test the arterial blood pump module as follows:
1. Remove the blood pump rotor by opening the door, pulling out the handle
and turning the rotor 90 degrees
2. Clean the rollers with a cloth dampened only with water.
3. With the crank lever pulled out, locate and lubricate the crank lever retainer
ball. If the crank lever is hard to pull out, replace the crank lever retainer
assembly (part number 564301).
4. Without removing the plastic sleeve, inspect the solid guide post on all four
(4) tubing guides. The solid guide post should not be loose or bent. If any
of the solid guide posts are loose or bent, the rotor assembly needs to be
replaced (part number M30990).
Note: The plastic sleeve will make it feel like the solid guide post is loose.
When inspecting, pay close attention to the movement of the metal shaft.
5. Clean the inside of the blood pump housing with the damp cloth.
Compressed air may be used if it is available.
6. Remove the blood pump module from the machine and inspect the motor
gearbox. In heavy use, some oil may accumulate on the gearbox housing.
Wipe the housing clean.
7. Wipe the lower edge of the module and the blood pump cabinet opening to
remove any residual disinfecting agent.
8. Reassemble the blood pump module and reinstall it in the machine cabinet.
When installing the module screws do not use a power screwdriver.
9. Place the machine in Dialysis Mode and clear all blood alarms.
10. Start the blood pump if it is not already running.
11. Open the blood pump door. Verify that the red alarm light on the blood
pump module lights within 15 or 30 seconds.
Note: Delay time before the blood pump alarm lights is set by dipswitch 4 on
the LP955 blood pump board.
