Problems solved by technology

[0004] At present, the method of adding pathogen inactivating agent at home and abroad is to directly add low-concentration liquid pathogen inactivating agent or solid pathogen inactivating agent. The liquid pathogen inactivating photosensitizer will degrade quickly at low concentrations and lose the pathogen inactivating effect. The solid pathogen inactivator has inaccurate and uneven single dose, and it is difficult to solve the problem of sterility, no pyrogen and no insoluble particles of the pathogen inactivator and the added excipients

Abstract

The invention relates to the technical field of blood pathogen inactivating agent composition and preparation method used for photochemical pathogen inactivation of blood or blood components for clinical transfusion. The polyester film adsorbed with a blood component pathogen inactivating agent according to the present invention, wherein the inactivating agent is a composition composed of a photosensitizer for inactivating blood or blood component pathogens and an auxiliary material that can be infused intravenously, and the polyester film is a drug. polyester film used. The polyester film composition adsorbed with the blood component pathogen inactivator of the present invention can be stored for more than 2 years, and its content is reduced by no more than 3%; the dosage of the pathogen inactivator of the single-chip composition is accurate, and can reach 95-95% of the marked amount. 105%; sterile, no pyrogen, no insoluble particles, meet the requirements for intravenous injection, thus solving the scientific preparation and addition of pathogen inactivation agents for photochemical pathogen inactivation of plasma or blood components.

Description

technical field [0001] The invention relates to the technical field of blood pathogen inactivating agent composition and preparation method used for photochemical pathogen inactivation of blood or blood components for clinical transfusion. Background technique [0002] Blood transfusion is an important means of support in modern medicine. Whole blood transfused clinically is a broad connective tissue composed of plasma and various blood cells. Whole blood can be separated into red blood cells, platelets, granulocytes, plasma and cold blood by physical methods. Precipitation and other blood components, and the blood transfusion method of using blood components for different diseases is called component blood transfusion. Compared with whole blood transfusion, component blood transfusion has the advantages of remarkable clinical effect, low incidence of adverse reactions, easy storage and saving blood resources, etc., so it is widely used and becomes the main form of clinical ...
