HEMOTHERM MODEL 400CE

WARNING

A physician's order is required for use and the setting of equipment and blanket temperature. Check patient's temperature and skin condition of areas in contact with blanket; also, check blanket water temperature at least every 20 minutes, or as directed by physician. Pediatric patients, temperature-sensitive patients with vascular disease, surgical patients, diabetics and Raynaud’s 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 HEMOTHERM is to be operated by a professionally trained perfusionist – with a physician’s order for use and the setting of equipment and blanket temperature.

Do not use the HEMOTHERM MODEL 400CE Blankets distal to arterial cross clamping.

Non-observance can lead to thermal injury.

Thermal injury may occur if heating/cooling blankets are used with a patient with an ischemic limb.

Perfusionist must operate the HEMOTHERM when connected to extracorporeal circuit heat exchanger. Lack of proper monitoring may result in serious injury or death.

The operator of the unit regulates the desired fluid temperature. Frequent observation of the actual blood temperature and body temperature is required.

Perfusionist must monitor equipment continually during machine operation to ensure there are no “alarms or intervention” required. Lack of proper monitoring may result in serious injury or death.

No modification of this equipment is allowed without prior, written authorization from CSZ.

Failure to do so may result in damage to the HEMOTHERM system and/or patient injury.

The method of temperature control provided by all cooler/heater units presents the danger of heating or cooling body tissues, particularly the skin and or blood, 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. Failure to do so may result in tissue injury.

Do not place additional heat sources between the patient and blanket. Skin damage may result.

Prep solutions have been reported to injure the skin when allowed to remain between patients and a water-circulating heating blanket during prolonged procedures. The area between the patient and the blanket should be kept dry to avoid injury to patient.

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 or sepsis and infection may result.

Upon receipt of the HEMOTHERM, the unit should be disinfected per the WATER SYSTEM CLEANING & DISINFECTION PROCEDURE. Additionally, any unit removed from storage should be disinfected. Failure to do so could result in patient and/or caregiver infection.

Do not use the HEMOTHERM system in the presence of flammable anesthetics. Risk of explosion can result.

Power interruption will cause the HEMOTHERM to revert to FILL MODE 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.

OPERATION MANUAL

HEMOTHERM MODEL 400CE

SECTION 1. INTRODUCTION

To provide the maximum patient safety during the use of the HEMOTHERM Model 400CE Dual Reservoir Cooler/Heater system, a thorough knowledge and understanding of the system, and its correct application and operating use are required. Each person who is responsible for use or direction of use of the system, such as physicians, perfusionists, technicians and operators must read and understand this operating manual and all precautions and warnings prior to use. It is recommended that this manual be reviewed at least semi-annually as a refresher for safe operation and application. For proper knowledge and understanding, in-service is available upon request.

All service associates, who interface with this equipment, must read and understand this Operation Manual in its entirety prior to maintaining or operating the equipment.

1.1GENERAL SAFETY PRECAUTIONS

The HEMOTHERM has internal self-diagnostics that could prevent the equipment from operating improperly. The most serious of these are the Remove from Service (RFS) alarms. The RFS alarms will require the equipment to be repaired immediately. They are indicated by an “EE” on the Heat side temperature display and a number on the Cool side temperature display. Too high of a temperature in the heat reservoir is also an RFS alarm and will be indicated by the appropriate red LED indicator. All RFS alarms will be announced by an audible alarm that cannot be muted.

High and low temperature limiting thermostats are preset at the factory and should perform satisfactorily for the life of the HEMOTHERM unit. Except for refrigeration component repairs, the repair and servicing of the HEMOTHERM unit requires no special tools. However, no attempt should be made to perform any of the repairs or service procedures outlined in this manual unless the proper skills and knowledge are possessed.

If water is found leaking into or around the HEMOTHERM unit prior to or during the operating procedure discussed here, immediately disconnect power to the unit and correct the malfunction before proceeding.

Before performing any disassembly procedure, press the power switch to the OFF/“O” position and unplug power cord from receptacle.

Exercise extreme caution if this equipment is used on electrically susceptible patients (probe, catheter or electrodes directly connected to the heart). Always test for current leakage before returning unit to service. Additional warnings are expressed at appropriate points in the manual.

See the Warnings and Cautions in the front of this manual.

OPERATION MANUAL

HEMOTHERM MODEL 400CE

1.2INTENDED USE

The HEMOTHERM® Model 400CE Dual Reservoir Cooler/Heater is used to lower, maintain, or raise the temperature of the water flowing through a Blood Oxygenator / Heat Exchanger that is used to cool or warm blood during cardiopulmonary bypass procedures lasting six hours or less. The Hemotherm Dual Reservoir Cooler/Heater may also be used with a hyper / hypothermia blanket under the patient to provide warming through conductive heat transfer.

The HEMOTHERM is capable of delivering temperature controlled water to blood heat exchanger(s) and one (1) blanket in the full range of controllability between 3°C - 42°C.

There are many variables that affect the heating or cooling of the patient in the extracorporeal circuit. Some of these include the patient's weight, blood flow, gas flow and oxygenator/heat exchangers. The HEMOTHERM has been designed to provide high water flow rates at low pressure for safe and highly efficient operation with a blood oxygenator/heat exchanger.

The HEMOTHERM can help maintain normal body temperature (normothermia) particularly during lengthy surgical procedures or where the ambient (room) temperature is set low. This can be done with the use of a Hyper-Hypothermia blanket underneath the patient.

1.3DESCRIPTION, EXTERNAL FEATURES AND PRODUCT PARTS

The HEMOTHERM Model 400CE Dual Reservoir Cooler/Heater consists of a primary unit that has a water cooling system and a water heating system. These share a common pump, filter and distribution outlet connections. Each water cooling/heating system has its own reservoir, cooler/heater hardware, water level switch, temperature sensor and associated plumbing.
