Blood and Anticoagulant Pumps
Note:
Cleaning of the pump rotors and pump housing is recommended
monthly and following fluid spills. A buildup of tubing debris or
fluids may interfere with pump efficiency. The following cleaning
method is recommended.
1. Loosen and remove the pump rotor screw from the center of the pump
rotor as shown in Figure 8-2.
2. Lift the pump rotor out of the pump housing.
3. For routine maintenance, using lint-free gauze or toweling moistened
with clear water, wipe the entire pump rotor. Clean all debris from the
rollers of the pump rotor.
Note:
In the event of a fluid spill in a pump, wash the pump rotor with
cleaning solution followed by a clear water rinse. Do not immerse
the pump rotor in water for an extended period of time.
4. Use lint-free gauze or toweling to dry the pump rotor. If available,
compressed air may be used to dry the pump rotor.
5. Ensure all rollers spin freely on the pump rotor.
6. Clean the pump housing and shaft using lint-free gauze or toweling
moistened with clear water. Remove all debris from the pump housing
and shaft.
Note:
In the event of a spill in the pump, clean the pump housing and
shaft with lint-free gauze or toweling moistened with cleaning
solution followed by a clear water cleaning as described above. Do
not spray the cleaning solution directly into the pump housing.
7. Dry the pump housing and shaft using lint-free gauze or toweling.
