APPARATUS FOR DEFROSTING OF CRYOGENICALLY PRESERVED BIOPRODUCT Russian patent published in 2005 - IPC

FIELD: heat-exchanging equipment used in medicine, in particular, in blood transfusion stations.

SUBSTANCE: apparatus has screened working chamber and cylindrical vessel made from dielectric material and located inside working chamber for rotation by means of electric engine, and temperature sensors connected to control unit. Netted container of dielectric material is provided with openings formed in bottom and wall. Dielectric used has low melting temperature and is adapted for filling of cylindrical vessel, netted container and for surrounding non-metal container filled with bioproduct to be defrosted. Temperature sensors are located inside netted container in the vicinity of non-metal container. Additional emitter with microwave energy source is positioned at opposite side with respect to first emitter and is connected to control unit. Control unit output is coupled to temperature regulator, which is connected to heating members placed inside dielectric material in lower part of cylindrical vessel.

EFFECT: increased efficiency and provision for uniform distribution of temperature through the entire volume of bioproduct under defrosting process.
