THERMOSTAT FOR STORAGE AND TRANSPORTATION OF BIOLOGICAL SUBSTANCES

摘要

FIELD: medicine. ^ SUBSTANCE: invention relates to medical equipment, in particular to constructions of portable medical thermostats. Thermostat for storage and transportation of biological substances contains case with lid and brought into heat contact with thermoelectric battery working chamber of compression refrigeration unit in which placed are detachable thermo-containers with single-stage and two-stage thermoelectric battery. Withdrawal of heat from hot soldered joints of thermoelectric battery in stationary conditions is carried out by compression machine evaporator. During transportation of biological substances thermo-container is placed into a special external case, withdrawal of heat from hot soldered joints of thermoelectric battery being carried out by means of heat tubes installed in external case frame, power feeding of thermoelectric battery with electric energy is performed by detachable accumulator source of constant current installed into external case frame. ^ EFFECT: improvement of technical and economical indices and increase of thermal stabilisation during storage and transportation of biological substances. ^ 2 dwg
