Abstract

The invention relates to a method and a device for treating in-vitro blood. The device consists of a lead comprehensive treatment box and an electric and control part, wherein an irradiation cavity is arranged in the treatment box; a front bin gate is arranged outside the treatment box; and an upper top plate is provided with an X-ray incidence window, an X-ray tube and a halogen lamp. During operation, an in-vitro blood sample with methylene blue photosensitizer and to be treated is arranged in the irradiation cavity; the X-ray tube and the halogen lamp can be started to operate after the front bin gate is closed; the X ray is emitted downward through the incidence window and irradiates the blood sample; the halogen light directly irradiates the blood sample; and the irradiation treatment of killing virus in the blood sample and the methylene blue chemical treatment of killing lymphocyte with immunocompetence are carried out simultaneously on the in-vitro blood in the same treatment cavity with high efficiency, high quality and low cost. Two processes for substep chambered single treatment are carried out in the same cavity, so that the treatment space is effectively compressed, the treatment time is shortened, the treatment cost is reduced, the treatment quality is improved, and strong practicability is ensured.

Description

technical field [0001] The invention relates to the technical field of blood treatment, in particular to a method and device for treating isolated blood with high efficiency, high quality and low cost. Background technique [0002] In the medical field, for the isolated blood collected from the human body, it is necessary to kill the viruses that may infect hepatitis B and AIDS in the blood before transfusion to the patient, and the killing may cause "transfusion-related graft resistance." Treatment of immunocompetent lymphocytes in patients with host disease (TA-GVHD) to reduce transfusion reactions and improve transfusion safety. "Transfusion-associated graft-versus-host disease (TA-GVHD)" is one of the most serious rejection reactions that may be caused by the human body after receiving blood transfusion. Although the incidence rate is only 0.1-1%, there is no specific treatment, and the mortality rate Up to more than 90%. At present, the effective way to prevent TA-GVH...
