Handling blood or plasma by EM radiation - in wavelength region of 200 to 320 nanometres at radiation intensity of 1 joule to 1 kilo-joule per sq. metre

摘要

The blood or plasma is irradiated directly after and/or before the material exchange process (haemo-dialysis or plasmapheresis) without direct contact through the conveying system (1). The inner surface of the material transfer system is subjected to a radiation intensity of 1J to 1KJ/sq.m. The start and stop of the radiation are set by a timer circuit. The whole radiation regime is carried out by a microcomputer (8). A hemispherical reflector (3) is fixed to a holder for an u.v. radiator with filters. The spectral power distributors of the radiator is variable. USE/ADVANTAGE - Haemodialysis, plasmapheresis and transfusion. Reduces cost of equipment to maintain quality of blood or plasma. Avoids side effects and reduces risk of embolism.
