Hose Kits
The MCH Series supports multiple hose kit configurations, to suit the growing array of perfusion
applications. With any hose kit, quarterly maintenance must include checking the connectors for
leaks, and tightening the clamps if needed. The plastic tubing must also be inspected at least
quarterly, and replaced when it becomes clouded, or when the plastic loses its flexibility.
Antimicrobial tubing should be replaced every two years, as its antimicrobial properties diminish
with long-term use.
Standard Hose Kit
The MCH Series includes a Standard Hose Kit, with
dripless connectors at one end, nylon-reinforced PVC
tubing, ball valves and a short section of flexible clear
tubing at the oxygenator end. Standard lengths are 10ft
(3m) for the MCH-1000(i) and 6ft (1.8m) for the
MCH-1000(m).
Dripless Anti-Microbial Hose Kit
The optional Dripless Anti-Microbial Hose Kit keeps
cooler-heater water away from the operating room
environment, reducing the risk to the patient of
secondary infections from exposure to water-borne
pathogens. The kit incorporates dripless connectors at
both ends, and silver-impregnated antimicrobial PVC
tubing to resist biofilm formation. These features help to
improve water quality, extend the useful life of the
tubing, and, when used properly, eliminate oxygenator-
side water leakage during connection and disconnection.
At the end of a procedure, leave the brass Hansen
connectors attached to the CPB heat exchanger, and
disconnect the dripless connectors. The short sections of
hose can be taken out of the room along with the heat
exchanger, then disconnected, drained, and returned to
the room post-procedure.
Custom Hose Kits
Hose kits can be customized for particular applications. Contact
CardioQuip for assistance in developing and validating custom
hose kits for use with your MCH Series device.
