WARNING • A 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 patients, temperature-sensitive patients with vascular disease, surgical patients, diabetics and Raynauds disease 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., burns or frostbite, respectively. Depending on the extent and severity of a burn, very serious and even fatal complications may arise. Prevent excessive and/or prolonged tissue pressure and shearing forces, especially over bony prominences, to prevent skin damage that may result. 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. Prep solutions have been reported to injure the skin when allowed to remain between patients and a water-circulating heating blanket during prolonged procedures. Proper sanitation procedures must be practiced and hygienic safety must be maintained, to prevent contamination. Contamination can affect patient’s health, i.e. skin irritation/rash may result. Use only YSI 400 Series, or equivalent, probes on CSZ equipment (refer to Figure (6-8.)). Failure to do this will cause incorrect temperature readings and may result in inadequate/inappropriate treatment. Do not use the BLANKETROL III system in the presence of flammable anesthetics. Risk of explosion can result. Power interruption will cause the BLANKETROL III to revert to CHECK SET POINT resulting in no therapy to the patient. Follow instructions for desired mode to resume operation. Failure to resume therapy could result in serious injury or death. Do not by-pass ground lug. Electrical Hazards may result. Any time water is found leaking into or around the unit, connecting hose, and/or blanket, turn the unit off, disconnect the power cord from its power source, and correct the problem before proceeding. Water leaks could lead to electric shock. Water leaks present a risk of infection and should be handled accordingly. Proper sanitation procedures should be followed including, but not limited to, the preventative maintenance described in this manual. Leaky blankets or hoses, as well as unapproved blankets or hoses should never be used. Exercise extreme caution if the unit is used for patients who are electrically susceptible (probe, catheter, or electrodes connected to the heart). Do not position unit near any objects that can generate a strong electrical/magnetic field. Unit has been investigated to be in compliance with IEC 60601-1-2. Potential electromagnetic interference may result. Always unplug the unit before accessing internal components during service. Failure to unplug the unit could result in electric shock. • • • • • • • • • • • • • • Manual 56201 Rev. A, ECN: M602-3259 .

PHYSICAL DESCRIPTION OF THE BLANKETROL III UNIT See Section (7) for specifications and certifications of the BLANKETROL III. 1-4.1. EXTERNAL FEATURES - FRONT VIEW The external features in Figure (1-1) of the BLANKETROL II unit are described as follows: A. The control panel is composed of pressure sensitive touch switches, nine LED indicators, a liquid crystal display, and two LED displays. An expanded description of the membrane control panel is presented in Section (1-4.4). The power switch is a bevel rocker switch labeled “I” (on) at the top and “O” (off) at the bottom. The switch lights up green when the unit is on. A circuit breaker is builtin the switch to protect against overload conditions. The storage drawer tilts out from the top to provide storage space for items such as probes, connector cables, connecting hoses, the drain hose, and the Operator's Manual. The grill permits air to be drawn into the unit and pass over the condenser. The air is then discharged through the bottom of the unit. The grill and compressor should be kept clear from blockage and cleaned regularly as described in Section (4-4.). For example, keep grill away from curtains and other obstructions. The protective bumper guard surrounds the lower edge of the unit and protects the unit as well as the walls. Four conductive, swivel casters are specially designed to permit the unit to move easily and to prevent it from tipping. B. C. D. E. F. 4 Manual 56201 Rev.

EXTERNAL FEATURES - RIGHT SIDE VIEW The external features in Figure (1-2.) of the BLANKETROL II 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. The water flow indicator only spins when a blanket or by-pass hose is connected to the unit. It will not spin when water is circulated internally to pre-condition the water. A total obstruction of the water path will cause the paddle wheel to stop completely. B. C. D. E. F. G. The recessed handle permits the operator to grip the unit when moving it. The four capped screws on the right and left side of the unit secure the top to the base. The patient probe jack is where the 400 Series probe (refer to Figure (6-8.)) is connected to the unit. Only one patient probe can be connected at a time. Three female, quick-disconnect return couplings on the top row are designed for water to flow in when the male coupling of the connecting hose is attached. The three male quick-disconnect outlet couplings on the bottom row are designed for water to flow out when the female coupling of the connecting hose is attached. The power cord with a hospital-grade plug should only be inserted into a properly grounded hospital grade receptacle for 115 VAC units and 230 VAC units.

MAINTENANCE OF THE HYPER-HYPOTHERMIA BLANKETS This section describes the general maintenance and repair procedures for the PLASTIPAD (reusable) and MAXI-THERM, and MAXI-THERM LITE (disposable) blankets. General maintenance tasks include cleaning, draining, and storing the blankets. Repair procedures are included for the PLASTIPAD blankets. 4.6.1 PLASTIPAD REUSABLE BLANKET Cincinnati Sub-Zero reusable plastic blankets (PLASTIPAD) are constructed from rugged polyurethane. This extra-strength material helps resist punctures and provides triple the seam strength of most other plastic blankets. Because of our irregular flow design it allows even temperature distribution and faster water circulation which results in better cooling and heating rates. Because it is nonporous, stains and debris can be easily wiped away with soap and water. If needed, cold sterilizable solution can be used for the O.R. The blankets may be gas sterilized; however, DO NOT exceed 140°F and aerate properly. 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). 64 Manual 56201 Rev.
