Description

CAUTION
• For grounding reliability, plug only into a properly
grounded outlet.
• Fill with distilled water only. Do not use alcohol.
Do not operate without water. Do not overfill.
Overfilling may result in overflow when the
water in the blanket/body wrap drains back
into the machine.
• Place a dry absorbent sheet between the patient
and the blanket when using the plastic-like side of
any blanket. Moisture may accumulate which
may result in skin damage.
• The POWER LOSS INDICATOR battery may discharge
if the Medi-Therm III machine has not been used
for two months or more. The battery may not
become recharged until the machine has
operated for four hours.
3.0 Description
The MTA7912 provides a means of regulating patient
temperature by supplying temperature-controlled
water through a connector hose to a hyperthermia/
hypothermia blanket/body wrap. The blanket/body wrap
provides an interface for heating and cooling the patient.
The machine controls the water temperature to a
prescribed set point.
The feedback for control purposes depends upon the
machine's operating mode. The machine may be operated
in one of three operating modes:
In BLANKET CONTROL mode, the operator sets the
desired water temperature. A temperature sensor within
the machine monitors the water temperature and the
machine heats or cools the water as required to bring
the water to the SET POINT temperature. The patient
temperature may be monitored by use of a patient probe
connected to the patient probe jack on the front of the
unit.
In PATIENT CONTROL mode, the Medi-Therm III machine
automatically regulates the patient's temperature to the
selected SET POINT. The machine constantly compares
actual patient temperature with the SET POINT value, and
automatically adjusts the water temperature so that the
desired patient temperature is achieved.
In MONITOR ONLY mode, the operator can monitor
patient temperature through the patient probe, without
providing therapy.

Hyperthermia/hypothermia blankets/body wraps may
be placed either under, over, or around the patient,
depending upon the type of procedure. Two gray hose
sets are provided to connect multiple blankets and/or
body wraps in order to provide more body surface
contact. Increasing body surface contact facilitates more
efficient warming/cooling.
NOTE: When connecting a second blanket/body wrap
to the Medi-Therm III machine, check the water level
(see Start-up Procedure, pp. 6-7) prior to connecting the
additional blanket/body wrap.
In the event of a power loss, a battery backup circuit will
light the POWER LOSS light and sound the audible alarm.
Upon restoring power, the mode of operation and the set
points will have to be reselected.
NOTE: Refer to the MTA7912 Medi-Therm III Service
Manual for information on maintenance/replacement of
the rechargeable battery.
The MTA7912 Medi-Therm III Service Manual contains
circuit diagrams, functional test information, and
component parts lists.
