Safety And Donor/Patient Care Precautions
4-3
P/N 39551-00, Rev. F
The owner should have a current leakage test performed regularly to ensure that
the machine continues to meet the 100/500 microampere or less standard. Par-
ticular attention should be given to current leakage after an event such as a saline
spill or major voltage surge in the house electrical system. See Chapter Six.
In view of the high conductivity of electrolytes, always avoid touching any por-
tion of the system with wet hands. Always work with clean, dry hands.
Rotating
Machinery
It must be recognized that even small, rapidly rotating parts have enough dynam-
ic energy to cause severe injury if any part of the person or clothing gets caught
in them. As a safety feature, the MCS+ device is equipped with a trip mechanism
that stops the Centrifuge if the cover is open.
Warning!
Persons operating this equipment or working near-
by should take the standard precautions applicable to all rotat-
ing machinery.
Communicable
Disease
Despite the application of all available tests to screen for communicable diseas-
es, such as hepatitis, HIV, or syphilis, there is always the risk that the blood being
processed is infected. Treat all blood as though it were infected; always clean up
spilled blood immediately.
Restrictions to
Flow
Warning!
No restriction to flow can be permitted in the
effluent line.
If the outlet port is inadvertently clamped off, pressure builds up in the processing
chamber to such an extent that the rotary seal is raised like a safety valve to re-
lease pressure. This results in the loss of the pocket of trapped air and the con-
tamination of the rotary seal faces with supernatant. Depending upon the nature
of the supernatant, the functional characteristics of the rotary seal may become
altered. Heating and wear effects may become quite noticeable, and in this case,
the contents of the bowl cannot be considered appropriate for reinfusion.
Warning!
Avoid blocking any tubing carrying blood from the
pump. A buildup of pressure in this tubing can result in the wide
dispersal of blood.
Observe the waste bag to verify that the accumulation of air in the air bag is not
being prevented by either a flow restriction or an air leak.
