Operation Overview; Add Ice - CardioQuip MCH-1000 Operators & Service Manual

Operation Overview

The MCH operating software serves two basic functions. First, it provides an intuitive, feature-
rich touchscreen control interface, giving the operator quick access to temperature settings,
pump speed control, system test and status information, and customization features. Second,
it constantly monitors the MCH's internal systems to ensure that the hardware is functioning
properly. An alarm will sound within seconds of any operational problem, alerting the operator
to the issue.
The operator controls the MCH using an LCD touchscreen display, using four basic modes. In
TESTING mode (which is run automatically when the system is powered on), the MCH tests all
internal relays and displays the results to the operator in a simple pass/fail format. In STANDBY
mode, the system is idle, awaiting operator input. In PRIMING mode, the MCH operates the
pump and valve to remove air from the tubing lines. In RUN mode, the device circulates the
water through the water tank and the heater chamber as necessary to maintain the circulating
water at the operator-selected temperature.
The MCH is designed with EMI protection to operate effectively with minimal interference from
other nearby equipment. It is shielded so that electronic noise generated within its enclosure
will not affect operation of other equipment in use in the same area as the MCH.

Add Ice!

The MCH uses sterile or 0.22-micron filtered ice-based cooling and has a valved, insulated
water tank that is able to retain ice for a considerable length of time. For procedures that do
not require extensive cooling, the MCH will operate safely and effectively with room-
temperature sterile or 0.22-micron filtered water in the tank; however, the temperature control
algorithms are optimized for the use of sterile or 0.22-micron filtered ice water. The MCH will
operate more efficiently with water (0-10˚C) in the tank.
