ASTOTHERM PLUS Instructions for Use

6 Product description 6.1 Introduction ASTOTHERM PLUS consists of a stand-alone Warmer and optionally of the additional active insulation ASTOLINE („S“-models). ASTOTHERM PLUS is a device for specific heating of blood and fluids which are delivered to the patients by transfusion, infusion or irrigation. The warming of the liquid supports the prevention and therapy of hypothermia during or after surgery; during longer procedures such as dialysis, hemofiltration, or apheresis the warming leads to a well-being. The applications of the ASTOTHERM PLUS therefore include transfusion, infusion, dialysis, hemofiltration and apheresis. The ASTOTHERM PLUS Warmer can be used to warm fluids administered to a patient at flow rates of 0 to 6000 ml/h (i.e. 0 to 100 ml/min), see figures 1 to 4. In the case of low flow rates, the re-cooling of the heated fluid on the way from the warmer to the patient is limited by using the active insulation ASTOLINE („S“ models only). The heated flexible silicone body surrounds the infusion extension on the way to the patient, ensuring that the part of the infusion line which would otherwise be exposed to cool ambient air is insulated and heated. Its special shape also enables infusions and transfusions to be observed all the way to the patient. The active insulation ASTOLINE and the infusion extension ASTOTUBE are considered as applied part acc. to IEC/EN 60601-1. 6.2 Technical description During operation of the Warmer heat is transferred from the internal heating element to the heat exchanger. Infusion extensions can simply be inserted in the circumferential groove. The heat from the heat exchanger is transferred through the inserted infusion extension to the fluid to be warmed. The temperature of the heat exchanger is monitored by a microprocessor controlled temperature control system and by two independent alarm systems designed to alert the operator to failure conditions and, if necessary, to switch off the heating process automatically in the event of excessively high temperatures. During operation, the mean temperature of the heat exchanger is displayed; this is not equal to the temperature of the medium to be warmed. ASTOTHERM PLUS neither regulates nor monitors/displays the current temperature of the medium to be warmed. The temperature of the medium (fluid) depends on a variety of factors, such as, but not limited to additional factors: • Room temperature and ventilation • Inlet temperature of the fluid (warmed-up or cold) • Flow rate The heat protection sleeve (option) protects infusions from the effects of external cold (e.g. air condition) and prevents heat being given off into the room.
