Abstract

An improved device, which uses cold red and infra-red radiation for the photodynamic stimulation of cells, specially cells of human tissue. The described improved device produces a constant energy radiation by help of semiconductor- and/or laser - diodes, which furthermore radiate light in more separate wavelengths due to a special operation mode. With help of sensors the advanced controller-system is able to test the patients for the needed radiation doses in order to avoid over-stimulation. Furthermore the radiation openings in the applicators are advantageable covered of a polarisation filter, whereby the absorption of the irradiated tissue is increased. The basic equipment consists of a moveable stand, with which machine-applicators are connected with a joint-arm. The machine-applicators are invented for the treatment of large area tissues, for example, the back of humans. The stand freely moveable on wheels consists of a control mechanism, whereby the different needed data for therapy can be adjusted and switched ON and OFF. The moveable stand is also connected with a hand-applicator designed for the treatment of small tissue-areas, e.g.
acupuncture points. Another version of hand-applicator is especially invented for dental treatment, whereby the head-piece of the hand-applicator can be connected with an expander containing an optical fiber.
