Use distilled waier only. Failure to use distilled water may result in poor
performance and damage to the 5LANKETR0L® II.
V
Do not use De-ionized Water. The majority of de-ionizers do not maintain a
neutral pH of 7. If the de-ionized water is acidic, it will cause a battery effect and
the copper refrigeration line will begin to deteriorate and cause a leak in the
refrigeration system.
Do not use alcohol. Alcohol may cause blanket deterioration.
Do not operate without water to avoid damage to intemal components.
Do not overfill. Overfilling may result in overflow when the water in the blanket
drains back into the system when the system is turned off.
The repair, calibration, and servicing of the BLANKETROL II should be
performed by qualified Medical Equipment Service Technicians, Certified
Biomedical Electronics Technicians, or Certified Clinical Engineers familiar with
good repair practices for se'^'icir.g medical devices, and in accordance with
instructions contained in this manual. Improper repair can result in damage
to the BLANKETROL !! system and patient injury.

А physician's order is required for setting blanket temperature and use of
equipment. At least every 20 minutes, or as directed by physician, check
patient's temperature and skin condition of areas in contact with blanket; also,
check blanket water temperature. Pediatric, temperature-sensitive, patients with
vascular disease, and operating room patients should be checked more
frequently. Notify the physician promptly of any change in patient status in
order to avoid serious injury or death.
The method of temperature control provided by all hyper-hypothermia units
presents the danger of heating or cooling body tissues, particularly the skin, to a
point where they are injured, i.e., bums or frostbite, respectively. Depending on
the extent and severity of a bum, very serious and even fatal complications may
arise.

Do not place additional heat sources between the patient and blanket.
Skin damage may result.
The area between the patient and the blanket should be kept dry to avoid injury
to patient.
Use only 400 Series, or equivalent, probes on CSZ equipment. Failure to do
this will cause incorrect temperature readings.

1 -2. GENERAL DESCRIPTION OF THE BLANKETROL I I SYSTEM
The CSZ BLANKETROL I I (Model 222R) Hyper-Hypothemnia System is used to lower or to raise
a patient’ s temperature and/or maintain a desired patient temperature through conductive heat
transfer. The CSZ BLANKETROL I I unit is composed of a heater, a compressor, a drculating
pump, and a microprocessor. This unit requires no field adjustments or calibrations in order to
maintain the precise measurement of temperature and temperature limits.
Water is heated or cooled and pumped from the unit to a blanket. The blanket* rests under and/or
on top of the patient and is designed so that the water circulates through the blanket and returns
to the unit.
If cooled water is circulated through the blanket, the desired effect is to reduce the patient's
temperature. If wanned water is circulated through the blanket, the desired effect is to elevate the
patient's temperature.
The BLANKETROL I I unit can be set so that it operates based on the temperature of the
circulating water (Manual Control) or it can be set so it cpei-ates bass:! on the temcr-"3^jre c'
the patient (Automatic Conirol).
* The recommended blanket(s) for use is described in Section (1-5.)
1 -3. CLINICAL APPLICATIONS
The BLANKETROL I I unit is used primarily in hospital Intensive and Coronary Care Units, in
Operating, Recovery and Emergency Rooms, in Bum Units, and on Medical/Surgical floors. This
hyoer-hypothennia system can be used with adult and pediatric patients to produce normothenmia
by lowering a patient's elevated temperature or raising a patient's sub-nonnal temperature. It can
also be utilized to maintain normal body temperature (nomnothemriia) during surgical procedures.
Surgically, this system can be used to produce moderate to profound hypothemiia for such
procedures as amputations, cardiopulmonary by-pass surgery, vascular surgery, and intracranial
surgery. Medically this system can be used to decrease the rate of circulation, to reduce
intracranial pressure, to control cerebral edema, and to reduce oxygen requirements. This
system is also used in the treatment of bums, shock, cardiac amest, and gastrointestinal
hemorrhage.
1-4. PHYSICAL DESCRIPTION OF THE BLANKETROL ! ! UNIT

1-4.2. EXTERNAL FEATURES - RIGHT SIDE VIEW V
The external features in Figure (1-2) of the BLANKETROL 1 1 unit are described as follows:
A . The water flow indicator is a paddle-wheel immersed in the path of the circulating
water with a window to the outside. As water is circulated through the system, it
must pass over the paddle-wheel causing it to spin (like a pinwheel). The water
flow indicator provides a visual display of the general rate at which the water is
circulating. For example, if the unit is circulating water but the connecting hose is
pinched, the circulation of the water is restricted. The change in water flow
decreases the speed of the paddle-wheel.
When the problem of the pinched connecting hose is solved, an increase in water
flow can be seen by watching the water flow indicator increase in speed. A total
obstnjction of the water path w ill cause the paddle-wheel to stop corr.pletely.
B . The recessed handle permits the operator to gr.p the ur.it v/her. rr';cv:ng it.
C. The four capped screws on the right and left side of the unit secure the top to the

1-6.2. COOLING SYSTEM V
The BLANKETROL II cooling system is composed of a compressor, condenser, condenser fan,
an evaporator coil, water temperature control, solenoid valve, hot gas bypass valve, and three low
temperature safety devices. Temperature ranges are described in Section (1-6.4.).
The refrigerant of the cooling system flows through the evaporator coil located in the circulating
reservoir. The water circulating in the reservoir flows over the evaporator coil and is cooled.
The cooling system is operational In the Manual Control or Automatic Control Modes whenever
the control system calls for a decrease in the temperature of the circulating water. It is important
to note that the rate of change in the circulating water temperature is not directly proportional to
the rate of change in the temperature of the patient.
1-6.3. CIRCULATING SYSTEM
Tne BLANKETROL 1 1 circuiaiing water system is composed of a magnetically driven circulating
pump, a dual compartment reservoir, a water filter, quick-disconnect fittings, connecting hose, and
hyper-hypothemnia blanket(s).
The 2 gallon (7.5 liters) capacity dual companment reservoir is composed of the circulating
resen/oir situated under and connected to the replenishing reservoir. When the operator fills the
reservoir with distilled water, the circulating reservoir fills first and holds approximately >2 gallon
(1.9 liters) of water. The remaining V/z gallons (5.6 liters) are held in trie replenishing reservoir.
The water moves from the replenishing reservoir to the circulating reservoir by gravitational pull as
needed.
The drculating water flows over and around the heating/cooling element located in the circulating
reservoir. The heated or cooled water then flows out the reser/oir to the circulating pump,
through the pump housing, through connecting hoses over a water temperature sensor to the
hyper-hypothermia blanket(s). The water circulates through the blanket(s) and returns to the unit.
The water then passes through the water flow indicator, through the water filter and retums to the
circulating reservoir to be reheated or recooled and then recycled.
In addition, the circulating reservoir contains a low water level sensor which shuts down the unit
and sounds the alanm if the water level drops below a preset amount. The unit becomes
operational only after the water level is restored to nonnal.
NOTE: DO NOT USE DE-IONiZED WATER.

1-6. FUNCTIONAL DESCRIPTION OF THE BLANKETROL II SYSTEM
In the Manual Control Mode, the operator sets the desired temperature of the circulating water.
The unit either heats or cools the water to reach the desired setpoint temperature. The water
circulates through the blanket and either raises or lowers the temperature of th e . patient. In this
case, the patient's temperature must be closely monitored. There is no constant relationship
between the temperature of the circulating fluid and the temperature of the patient or the change
in temperature of the patient.
In the Automatic Control Mode, the operator sets the desired temperature of the patient. In
addition, the operator must attach a 400 Series probe in or to the patient. The probe is then
inserted into the BLANKETROL II unit. The probe is used to measure the actual temperature of
the patient and this measurement is then compared with the desired Setpoint temperature by the
unit's microprocessor. If the actual patient temperature is lower than the desired patient
temperature, the BLANKETROL II unit heats the circulating water so that the temperature of the
patient is elevated to reach the desired Setpoint. At Setpoint, the unit continues to drculate the
water but the heater ceases to operate. When the patient’s temperature falls outside the Setpoint
range, the heater/compressor resumes operation, heating/cooling the water until the patient's
tsmperat'jre is спсз again at Setpcir.t.
If the actual temperature is higher than the desired patient temperature, the BLANKETROL II unit
cools the circulating water so that the temperature of the patient decreases to the desired Setpoint
temperature. At Setpoint, the unit continues to circulate the water, but the compressor stops.
When the patient’s temperature falls outside the Setpoint range, the compressor/heater resumes
operation, cooling/heating the water until the patient's temperature is once again at Setpoint.
in addition, the BLANKETROL II unit can be set to operate in a Monitor Only M ode. In this mode,
the 400 Series probe is attached to or inserted into the patient and is connected to the unit. The
operator then sets the BLANKETROL II unit to monitor and display the patient's actual
temperature. In this mode, the unit does not heat, cool, or circulate the water.
1-6.1. HEATING SYSTEM
The BLANKETROL II heating system consists of an immersion heater, water temperature control,
and three high temperature safety devices. Temperature ranges are described in Section (1-6.4.).
The immersion heater is located in the circulating reservoir. The water circulating in the reservoir
flows around the immersion heater and is warmed.
The heating system is operational in the Manual Control or Automatic Control Modes whenever
the control sys+en calls for an increase in the temperature of the circulating v/ater. It is important
to note that the rate of change in the circulating water temperature is not directly proportional to
the rate of change in the temperature of the patient.

1-6.4. TEMPERATURE SAFETY CONTROL SYSTEM
The BU\NKETROL II unit is designed to carefully measure and control the temperature of the
circulating water. The unit is engineered so that when the temperature of the circulating water
reaches the desired setpoint temperature, the unit operates between heating and cooling the
water in order to maintain the setpoint temperature. The unit is designed not to exceed or fall
below the desired temperature.
As a safety precaution, the B1_ANKETR0L II unit has three high temperature safety devices and
three low temperature safety devices.
Each safety device continuously monitors the temperature of the circulating water and almost any
possible failure is protected by a back-up system. As an additional precaution, if the water
temperature sensor itself should fail, the unit shuts down and indicates REMOVE FROM
SERVICE (Sensor). With this safety design, both the patient and the unit are protected from injury
or damage caused by extreme temperatures.
At the same time, the operator must regularly monitor the patient whenever hyper-hypothenmia
therapy is used.
SAFETY CONTROLS FOR PROTECTION FROM HIGH TEMPERATURE
Circulating water reaches 107.6°F ± 1°F (42°C - .5^0, microprocessor controls setpoint.
Circulating water reaches 112°F ± 4°F (44.6°C ± 2°C), safety device shuts off heater, status
display flashes "HI TEMP" and the microprocessor board beeper is sounded.
Circulating water reaches 115°F r 4°F (46°C ± 2°C), back-up safety device shuts off the unit and
indicates REMOVE FROM SERVICE AND H I LIMIT.

Effective use of the BLANKETROL II system must include proper patient care prior to and
while using the hyper-hypothenmia blanket(s).
CAUTION I
THE DESIRED SETPOINT TEMPERATURE SHOULD BE SET ONLY AS
PRESCRIBED BY AND UNDER THE ORDER OF A PHYSICIAN._______________
A. A base line recording should be made of vital signs, level of consciousness
and responsiveness.
B. A dry sheet or DISPOSA-COVER should be placed Ье^л/ееп the hyper-
hypothenmia blanket and the patient when using PLASTI-PAD, MAXI
THERM, crTEMP-PAD Blankets. The MAXI-THERM LITE Blanket does noi
require an inteфosed sheet.
Standard nursing procedures while usirg a hyper-hypothennia blanket include the
following tasks:
A. Patient's vital signs should be recorded and evaluated frequently. Operating
room, temperature sensitive and pediatric patients may deviate from nonmal
responses to extemal applications of heat and cold. Patient core temperature
and the condition of the skin in contact with the blanket and blanket water
temperature should be checked every twenty minutes. Operating room,
temperature sensitive and pediatric patients should be checked more
frequently. Notify the physician if the patient's core temperature does not
reach the prescribed temperature in the time prescribed or deviates from the
> prsscribed temperatura range.
B. The position and the placement of the probe should be inspected regulariy.
Also, the BLANKETROL II unit activates an alarm when the patient probe
registers outside the range of 30°C - 43.5®C (86®F -11 ОТ).
C. Level of consciousness, strength of extremities, changes in cardiac rate,
changes in cardiac rhythms, pupil size, and response should be observed
and recorded.

B. Lift the water fill opening lid and gradually pour approximately 2 gallons (7Уг
liters) of distilled water (or the distilled water-bacteriostatic preparation
described in Section (4-2.) into the reservoir (DO NOT USE ALCOHOL OR
DE-IONIZED WATER).
C. Stop pouring when the water reaches the strainer visible at the bottom of the
water fill opening.
D. Proceed with normal operations; always check the Vvater level before starting.
MAINTENANCE OF THE WATER FILTER
The BLANKETROL II circulating system includes a water filter designed to clear the line of
any particulate matter as the water is pumped through the system. As shown in Figure (5-
1), the water filter assembly is a plastic T-shaped fitting that intersects the hose from the
water flow indicator to the reservoir. A stainless steel wire-mesh screen is located inside
the clear plastic cap of the water filter assembly.
Once every six months, or more often if deemed necessary, the water filter should be
disassembled and cleaned. To do so, the reservoir must first be drained and the rear
enclosure panel removed. The cap of the water filter assembly is unscrewed. The wire ^
mesh and the plastic cap are cleaned. The parts are then reassembled.
After draining the reservoir as described in Section (4-2.1.):
A. Disconnect the unit from its power source.
B. Using a Phillips head screwdriver, remove the four screws of the rear
enclosure panel. Guide the panel towards the floor so the tab along the top
edge of the panel clears the bottom edge of the top assembly.
C. Locate the water filter assembly as shown in Figure (5-1).

4.6.1 PLASTIPAD REUSABLE BLANKET
Cincinnati Sub-Zero reusable plastic blankets (PLASTIPAD) are constmcted from mgged
polyurethane. This extra-strength material helps resist punctures and provides triple the
seam strength of most other plastic blankets. Because of our random flow design, it
allows ever, temperature distribution and faster water circulation which results ir better
cooling and heating rates. Because it is nonporous, stains and debris can be easily
wiped away with soap and water. As necessary, cold sterilizable solution can be used for
the O.R. The blankets may be gas sterilized, however, DO NOT exceed 14C^F and
aerate properiy. DO NOT AUTOCLAVE!
The blanket should not be drained after each use. Water remaining after use will not ®
damage the blanket. If it becomes necessary to drain the blanket, remove both the male ) '!
and female fittings on the hose leading from the blanket. Insert a compressed air nozzle !
into one end of the connecting hose and force the water out the other end with
compressed air (10 psi maximum). After the water is removed, apply silicone
caulking/teflon tape around the threads of the hose barbs. Reattach the male and female
fittings onto the hoses.
PLASTIPAD blankets can be patch repaired if the blanket is punctured and begins to
leak. A PLASTIPAD Patch Kit with instructions is available at no charge upon request.
To store PLASTiPAD blankets, loosely coil the hose lengthwise into the center of the
blanket. Fold the blanket lengthwise into the center, 1/3 from the left side and 1/3 from
the right side. Do not fold the blankets width-wise, as doing so will crimp the tubing.

4-6.2. MAXI-THERM , MAXI-THERM LITE, and TEMP-PAD (DISPOSABLE) HYPER
HYPOTHERMIA BLANKETS
The reusable blanket maintenance procedures do not apply to these single-patient use
blankets. These single-patient use blankets offer the highest flow rate with a random flow
pattem of any disposable blanket system. This results in less temperature differential
between the blanket surface and the reservoir fluid in the unit while providing maximum
thermal transfer from blanket to patient. Easy-to-use color-coded quick connectors and
shut-off clamps make set-up and disposal a "snap”. Maximum patient comfort is assured
by a soft, opaque vinyl or r.cn-v;cver. surfccs wtnCh produces a cushioning effect. The vinyl
surf^s^o blankets can be wipea ciecii • if soiled in use enabling them to last for the duration of
the average patient stay.

Щ 4-7. MAINTENANCE OF REUSABLE THERMISTOR PROBES
Г The standard 400 Series probe consists of a thermistor temperature sensing element
housed in a probe and attached to a plasticized vinyl-jacketed, shielded, lead wire
temriinated with a phone plug. Refer to the printed material enclosed with each probe
regarding temperature specifications, cautions, and maintenance.
In general, clean with a damp cloth and mild detergent. When not in use, the probes
should be loosely coiled and stored at room temperature. Never boil or autoclave the vinyl
jacketed leadwire. Avoid contact with strong aromatic chlorinated, ketone, ether, or ester
solvents.
When cleaning or sterilizing, the probe should be handled gently. Excessive pressure can
stretch the covering and/or break the intemal wires. At high temperatures, the vinyl softens
and can be deformed by pressure and stress. DO NOT AUTOCLAVE.
L
Probes may be disinfected and sanitized by washing with 3% hydrogen peroxide or 70%
Щ isopropanol. Brief immersions in detergent solutions are not harmful. Prolonged
immersions in detergent solutions will cause the vinyl to lose flexibility. Phenol disinfectants
should be avoided. Ethylene oxide sterilization does not damage the probe, but gas is
highly irritating and is absorbed by the plastic parts. Directions given by the manufacturer of
the sterilizer must be closely followed, especially regarding temperature and aeration.

DO NOT IMMERSE THE PROBE-JACK PLUG CONNECTOR IN LIQUID.
4-8. MAINTENANCE OF THE WATER CIRCULATING SYSTEM
The BLANKETROL II water circulating system includes the pump, operating resen/oir,
replenishing reservoir, water flow indicator, water filter, fittings, and all interconnecting
tubing. To clean the circulating system: See Section 4-2. - SUGGESTIONS FOR

5-19. REFRIGERANT CHECK
The BLANKETROL II unit cooling system includes a sight glass to check the refrigerant
flow.
For best operation, the system should have a full flow and a dry system.
The center dot of the sight glass should be a pale green at all times to indicate a dry
system. A yellow dot indicates a moist system and a possible leak. When the unit is
operating in the cooling cycle, the sight glass should be full with no bubbles. This can be
checked by setting the unit to operate in the Manual Control Mode so that the Status
display shows cooling and watching the liquid fill-up the sight glass. During this check,
there must be at least 2°C (4°F) difference between the SETPOINT temperature and the
BLANKET/WATER temperature. If the temperatures are set closer, the sight glass may
show chuming bubbles or be only half full.
81
--- стр. 91 ---
NOTE: THE CHECK MUST BE DONE ONL Y WHEN THE UNIT OPERA TES IN THE
COOLING CYCLE.
\
Bubbles in the sight glass may indicate a shortage of refrigerant and a probable leak.
If there is less than full flow, a qualified refrigeration technician should charge the unit until a
full flow is attained. DO NOT OVERCHARGE. The system charge is approximately 13
ounces of R134A. Only a qualified refrigeration technician should repair a refrigeration leak,
contact CSZ service department.
5-20. LOW LIMIT SAFETIES CHECK
A. Remove the four capped screws and lift the top carefully. (DO NOT
DISCONNECT ANY WIRES.)
B. Remove the white/yellow wire from the rear (upper) tenninal of the 3 pole (K-
4) relay socket. Insulate this wire to insure it will not short against any other
terminals or metal parts.
C. Attach a 16 gauge wire approximately 7" long (stripped at one end and with
an alligator clip on the other end) to terminal #1 of the 3 pole relay socket (K-
4) and to the slide on terminal of the bridge rectifier where the white/b^je wire
is connected.
D. Due to the "test wiring" being installed, the unit will cool down to 3® C ± 1 °C
(37°F ± 2°F). At this point the audible alarm will sound, the status display will
indicate LOW-TEMP and the refrigeration solenoid will be de-energized. The ^
LOW TEMP alanm will rescued at one (1) minute intervals when the silence
alanm key is pressed. It will be necessary to silence this alarm for the )
duration of the LOW TEMP/LOW LIMIT safeties check.
NOTE: THE LOW TEMP ALARM IS THE MICROPROCESSOR
