Connectors, Valves, & Hoses; Main Hose Connectors - CardioQuip MCH-1000 Operators & Service Manual

CONNECTORS, VALVES, & HOSES
The MCH series utilizes various non-spill connectors and valves to provide a convenient, drip-
free water path. Note that the brass Hansen-style connectors at the remote (oxygenator) end
of the standard hose kit are not valved, and will leak when disconnected.
WARNING: This device must not be connected to a heat exchanger or blanket
with a manufacturer recommended maximum pressure rating of less than 83
kPa (12 psi). Rupture or leakage may occur in the heat exchanger, resulting in
patient injury and/or damage to the system.

Main Hose Connectors

The large dripless connectors on the rear panel of the
MCH are for connections to arterial and/or cardioplegia
heat exchangers. Maximum water flow at the main
connectors is 42 liters/minute (11 gallons/min) with open
connectors (unrestricted flow). Actual water flow when
connected to a heat exchanger will vary, depending on
the flow characteristics of the heat exchanger being used.
Water is routed directly from the pump to the OUT
connector and recirculated into the system at the IN
connector. Water at the OUT connector is under
pressure when the system pump is on. These connectors
are oriented horizontally on the MCH-1000(i), and
vertically on the MCH-1000(m).
Connecting Hoses
To connect a hose, firmly push the connector
straight in until it "clicks," as shown.
Disconnecting Hoses
To remove a hose, grasp the connector and
push the dark grey button on top of the panel
connector, as shown below. The connector is
spring-loaded and will pop out.
