Embodiment

[0044] like figure 1 As shown, a bacterial culture device based on a hemodialyzer includes a fluid circuit circulation unit, an environmental control unit and a drug delivery unit. The fluid circuit circulation unit includes a main culture bag 9 and a secondary culture bag 10. The culture bag 9 is connected to the inner two ends of the main body of the hemodialyzer 15 to form the main circulation circuit 1, and the secondary culture bag 10 is connected to the outer two ends of the main body of the hemodialyzer 15 to form the secondary circulation circuit 2. The main circulation circuit 1 is provided with a main circulation pump 3, a secondary circulation loop 2 is provided with a secondary circulation pump 4, the drug delivery unit 7 is connected with the main circulation loop 1, and the main circulation loop 1 and the secondary circulation loop 2 are provided with liquid. Road pressure detection device. Said liquid circuit pressure detection device includes a main circulatio...

Abstract

The invention discloses a bacterial culturing device based on a blood dialyzer, and belongs to the field of bacterial culturing. The bacterial culturing device based on the blood dialyzer comprises a liquid-path circulation unit, an environment control unit and a dosing unit, and is characterized in that the liquid-path circulation unit comprises a primary culturing bag and a secondary culturing bag, the primary culturing bag is connected with the two ends of the inside of a blood dialyzer body to form a primary circulation loop, the secondary culturing bag is connected with the two ends of the outside of the blood dialyzer body to form a secondary circulation loop, the primary circulation loop is provided with a primary circulation pump, the secondary circulation loop is provided with a secondary circulation pump, and the dosing unit is connected with the primary circulation loop. The bacterial culturing device is convenient to operate, accurate in measurement and high in expansibility and maintainability, and medical workers can conveniently perform medicine PD/PK research.

Description

technical field [0001] The invention relates to the field of bacterial culture, in particular to a bacterial culture device based on a hemodialyzer. Background technique [0002] PK is the effect of the body on drugs, including the dynamic changes of drug absorption, distribution, metabolism and excretion in the body. PD is the effect of drugs on the body (including pathogens), including the therapeutic effects and adverse reactions of drugs in the body. PK / PD research is to combine PK and PD to study the "time-concentration-effect" relationship corresponding to the drug dose, which can reflect the relationship between "drug-human body-pathogen". The object of antimicrobial action is not the body, but the pathogenic microorganisms that cause the body to infect the body, the drug exerts an antibacterial effect, and the body metabolizes the drug. The clinical pharmacology research content of antibacterial drugs mainly includes the research of pharmacokinetic PK and pharmacod...
