1.0 Indications for Use
For the prevention or treatment of hyperthermia/
hypothermia.
1.1 Contraindications
Patients with an elevation of cold agglutin levels (cold
agglutinemia) should not be placed on a cooling blanket/
body wrap.
In rare instances, the cold temperature of the cooling
blanket/body wrap may lead to acrocyanosis and
necrosis of distal body structures (Talisman, R., et al.
Surgery 123(5): 592-595 (1998).
2.0 Safety Precautions
Read and understand this operating manual and all
precautions listed below prior to using the Medi-Therm
III Hyper/Hypothermia Machine.
WARNING
WARNING
• If the patient’s temperature is not responding or
does not reach the prescribed temperature in the
prescribed time or deviates from the prescribed
temperature range, notify the attending physician
promptly.Failuretonotifythephysician
promptlymayresultinseriousinjuryor
death.
• When performing the PROBE CHECK, use a
protective sheath on the probe. Failuretousea
sheathcouldresultincross-contamination.
• A physician’s order is required for use of
equipment. Check the integrity of the skin
according to department protocol when
regulating temperature with external devices.
Frequency of assessment and documentation will
vary depending upon the individual response of
the patient.
 Failuretomonitorpatientmayresult
inskindamageorinappropriatepatient
temperature.
•Avoid placing additional heat sources between the
patient and blanket/body wrap.Skindamage
mayresult.
• Use only Gaymar probes (see Accessories, page 16)
or equivalentYSI 400 series probes approved for
use with medical devices in the Patient Probe jack. 
Useofotherprobescouldresultin
erroneouspatienttemperaturevalues.
• Prevent excessive and/or prolonged tissue
pressure and shearing forces, especially over
boney prominences.Skindamagemayresult.
•Keep the area between the patient and the blanket/
body wrap dry.Excessivemoisturemayresult
inskindamage.
• Donottipmachineoverwithoutrstdrainingthe
water out and unplugging the power cord. Damage
tothemachineorelectricalshockcanresult.
• Use of thermally conductive materials (e.g., water
or gel) on a patient when the Medi-Therm III
is switched off may decrease the patient's body
temperature.
• Repairsshouldbeperformedonlybyqualied
medical service personnel in accordance with this
product's service manual.Otherwise,damageto
themachineorimpropertherapymayresult.
• All wire-lead, patient-connected transducer
assemblies are subject to reading error, local heating,
and possible damage from high-intensity sources of
RF energy. Inadequately grounded electrosurgical
equipment represents one such source, since
capacitively-coupled currents may seek alternate
paths to ground through probe cables and associated
instruments. Patientburnsmayresult.
If possible, remove the probe from patient contact
before activating the surgical unit or other RF
source. If probes must be used simultaneously with
electrosurgical apparatus, hazards can be reduced by
selecting a temperature monitoring point which is
remote from the expected RF current path to the
ground return pad.
• When using the rate controlled Auto Moderate or
Auto Gradual modes for warming; switching to other
modes, e.g.Auto Rapid or Manual, or changing the
temperature set point during the therapy will cause
the Medi-Therm to reset the therapy. Alteringthe
ModeorTemperaturesetpointmayimpact
theoveralldurationofthetherapy.

CAUTION
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.
Description
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
efcient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.

6.1 BLANKET CONTROL
When operating in BLANKET CONTROL mode, the
Medi-Therm III machine regulates the water temperature
to the selected SET POINT. A temperature sensor within
the machine monitors water temperature, and the
machine heats or cools the water as required to bring it
to the SET POINT temperature.
In BLANKET CONTROL mode, the operator must observe
the patient’s temperature and manually adjust the water
temperature to obtain the desired results.
To operate in BLANKET CONTROL mode:
1. Perform all start-up procedures (pp. 6-7).
2. Press the BLANKET CONTROL button.The upper
window on the top of the BLANKET CONTROL
button will light.

the most comfortable setting for the patient.
MODERATE - water temperature is limited
to 15°C below the patient's temperature.This
will provide an improved comfort setting to the
patient.
GRADUAL - water temperature is limited to
10°C below the patient's temperature.This will
provide an improved comfort settting to the
patient.
WhenWARMINGthepatient*:
RAPID - the highest allowable water
temperature is used for warming - as high as
41°C.This is the fastest warming mode the
machine can provide.
MODERATE - the patient's temperature will
increase at a rate of 1°C in a period of 3 hours
(0.33°C/Hr).
GRADUAL - the patient's temperature will
increase at a rate of 1°C in a period of 6 hours
(0.17°C/Hr).
When using AUTO MODERATE and AUTO GRADUAL
for patient warming, NOMANUALINTERVENTION
is required once the patient set point temperature has
been selected for warming.
NOTE: In BLANKET CONTROL mode, if the machine
senses a patient probe temperature below 29°C or
above 40°C, the CHECK PATIENT alert will light and
audible alarm will sound.Therapy will continue.When
this occurs:
•Check the patient's temperature.
•Check also to determine if the patient probe
has become dislodged, an incorrect probe
is being used, or the probe has become
defective. See Troubleshooting (pp. 12-13).
The CHECK PATIENT alert will turn off and
the audible alarm will silence when the patient
temperature returns to the range of 29°C to
40°C.
6.2 PATIENT CONTROL
When operating in the PATIENT CONTROL mode, the

8.0 Safety Systems
8.1 Overtemp Safety Circuits
In the event of a controller failure, there are two separate
backup circuits which prevent the water temperature
from surpassing safe operating limits.
Therstovertempbackupconsistsofanelectronic
sensing circuit, totally independent of the main control
circuitry.This circuit will interrupt heater power and
initiate a REMOVE FROM USE NOW audible and visual
alert to keep the water temperature below 42°C.The
second overtemp backup is a bimetallic thermostat which

Troubleshooting
9.0 Troubleshooting
Check for hoses fully inserted, one into return (top) and one into supply (bottom).
Check to be sure all pinch clamps are open.
Check for kinked hoses or creased blanket/body wrap.
Make certain patient probe is fully inserted into the patient probe jack.
Check for secure connection to patient. (If probe is sensing ambient, alarm will sound.)
Check for proper type of probe (Gaymar probe or equivalent YSI 400 series probe approved
for use with medical devices) and adaptor, if needed.
ADD WATER
Check to make sure water is at the proper level. If the green band on the float is not visible, fill
machine with distilled water until the green band is visible.
REMOVE FROM USE
NOW
Indicates that the machine has shut down due to the water temperature exceeding the high or
low limit. Or, a system error has been detected. Remove the machine from use immediately
and notify medical equipment repair personnel.
Check to make certain power cord is fully engaged into properly grounded receptacle.
Make certain the receptacle has power.
Reset unit circuit breaker by turning OFF then ON. If circuit breaker trips again, refer to
medical equipment repair personnel.
Check for water circulating through the blanket/body wrap. See CHECK FLOW. Do not fold
blankets/body wraps.
Check to make sure the temperature controller is working by adjusting the setpoint (while in
BLANKET CONTROL mode) at least 2°C above the water temperature. This should cause the
WARMING indicator to light.
Check for water circulating through the blanket/body wrap. See CHECK FLOW. Do not fold
blankets/body wraps.
Check to make sure the rear and side vents are not blocked. Inlet and exhaust grills should be
kept clear and clean to allow air to circulate freely.
Check to make sure the temperature controller is working by adjusting the setpoint (while in
BLANKET CONTROL mode) at least 2°C below the water temperature. This should cause the
COOLING indicator to light.

WARNING
9.1 Probe Check
When performing the PROBE CHECK, use a
protective sheath on the probe.
(Becton-Dickinson catalog 3700 oral sheath
or equivalent.)
Failuretouseasheathcouldresultin
cross-contamination.
1. Insert probe into protective sheath and
then into PROBE CHECKWELL on front of
machinebase(g.7).
2. Operate machine in BLANKET CONTROL mode
with a blanket/body wrap connected. Adjust SET
POINT temperature to between 33°C and 37°C.
Wait until machine temperature stabilizes (both
the WARMING and COOLING lights are off and
patient temperature display stabilizes).Water and
patient temperature displays should read within
2°C of each other. If not, patient probe may be
defective or incorrect probe is being used.
 UseonlyGaymarprobesorequivalentYSI
400seriesprobesapprovedforusewith
medicaldevices.
3. If probe appears defective, try another probe and
repeat PROBE CHECK. If a new, correct probe
does not meet this test, remove machine from
use and request service.

10.0 Care and Cleaning
As with any precision equipment, proper care and
maintenance will insure proper performance and
reliability.The following routine maintenance procedures
will help insure dependable Medi-Therm III operation.
10.1 Machine Care
• Fill with distilled water only.
 Failuretousedistilledwatermayresultin
poormachineperformance.
• Donot use alcohol.Alcohol may accelerate
blanket/body wrap deterioration. Alcohol is
ammable.
• Donotoperate without water, since damage to
internal components may result.
• Donotoverll.Overllingmayresultin
overowbecausethewaterintheblanket/body
wrap drains back into the machine when the
machine is turned off.
• WhenllinganemptyMedi-ThermIIImachine,
add a small amount of germicidal or sanitizer
solution to the water (Air-Kem A-33 liquid or
equivalent). Carefully follow the manufacturer’s
recommended concentration to prevent algae
growth within the Medi-Therm III system and
Hyper/Hypothermia blanket/body wrap.
Donot use too much concentrate, since it
will result in “foaming,” which can reduce the
blanket/bodywrapefciencyandmaydamagethe
circulating pump.
•Donot use bleach. Bleach will damage the
heating element.
10.2 Draining the Machine
It is not necessary to drain the Medi-Therm III
machine after each use. However, periodic draining is
recommended at least once a month.
10.3 Machine Cleaning
Users should not use cleaning or decontamination
methods different from those recommended.
To clean the external surfaces of the machine and
connector hose, use a nonabrasive cleaning solution
(such as warm, soapy water) and a clean cloth.
Wipe or air dry.Apply a disinfectant such as 10%
chlorinated bleach solution (chlorinated bleach with
5.25% sodium hypochlorite) to the external surfaces
and allow to dry.
10.4 Blanket/Body Wrap Care
• Donotstorelledblankets/bodywraps.Algae
growth may occur inside.
• Do not use a blanket/body wrap if severe algae
buildup occurs.
• Do not expose blankets/body wraps to
temperatures over 65°C.
Disposable Blankets/Body Wraps
1. After the machine has been turned off, raise the
blanket/body wrap higher than the machine to
allow most of the water to drain back into the
machine.
2. Close both sets of hose clamps.
3. Disconnect the blanket/body wrap from the
machine.
4. Dispose of blanket/body wrap.
Reusable Blankets
1. After the machine has been turned off, raise the
blanket higher than the machine to allow most of
the water to drain back into the machine.
2. Close both sets of hose clamps.
3. Disconnect the blanket from the machine.
4. Manually clean both sides of the blanket on a
atsurfacewithwarmwater,amildcommercial
detergent, and a sponge or cloth.

7. Apply a disinfectant such as a 10% chlorinated bleach
solution (chlorinated bleach with 5.25% sodium
hypochlorite) to both sides of the blanket.
8. Allow to air dry. Solution contact time is what makes
disinfection effective.
NOTE: Excess solution pooled in the buttons can
be removed with a clean, dry cloth.
9. Loosely roll up the blanket and store for next use.
Reusable blankets can be cleaned and reused so
long as they do not crack or leak.
10.5 Probe Care
Reusable Probes
For cleaning, disinfecting, and sterilizing reusable Gaymar
probes (or equivalentYSI 400 series reusable probes),
refer to the instructions provided with the probe.
Disposable Probes
Gaymar disposable probes should be discarded after use.
10.6 Probe Check Well Care
The PROBE CHECKWELL should be cleaned with a
small tubular brush as outlined in section 10.3, Machine
Cleaning.
10.7 Quick-Disconnects
The quick-disconnects joining the connector hose to the
machinemaybecomedifculttoengage.Thisproblem
can be prevented by periodically applying a silicone base
or light machine oil to the outside of the male connector
prior to engagement.
10.8 Preventive Maintenance and Service
Preventive maintenance and service procedures are
described in the Medi-Therm III MTA7912 Service Manual.
These procedures should be performed annually (or as
requiredbyhospitalprotocol)byqualiedpersonnelsuch
ascertiedbiomedicalelectronicstechniciansorcertied
clinical engineers.
