A CSF management method for use with a patient forms a closed loop CSF circuit between two points on the patient's body. The CSF circuit has a therapeutic inlet to receive a therapeutic material (e.g., a drug), and a pump having a pump outlet to direct CSF along the CSF circuit. The method controls the pump to direct CSF from the pump outlet at a CSF rate that is different from the natural flow rate (i.e., the natural CSF flow rate). The therapeutic material is added to the CSF via the therapeutic input at a therapeutic rate. The CSF rate is different than the therapeutic rate and / or may be greater than the therapeutic rate. Alternative methods may control a bolus drug infusion to localize the application to a target region.

This invention relates to the field of medical data processing technology, and discloses a method, system, device, and medium for calculating the synergistic control rate of drug infusion. The invention acquires the patient's real-time bispectral index (BSE) and determines its deviation from a preset target range. A control algorithm is then used to calculate the required total effect intensity adjustment. Based on a preset fixed ratio of propofol and remifentanil effect-site concentrations, the total effect intensity adjustment is allocated to the target effect-site concentrations of each drug. Finally, the target infusion rates of propofol and remifentanil are calculated backward using the Schnider and Minto models, respectively. This invention achieves synergistic closed-loop control of sedative and analgesic drugs based on a single BIS feedback, solving the clinical problem of unquantifiable analgesia control, ensuring a dynamic balance between sedation and analgesia, and incorporating a built-in safety verification mechanism. This significantly improves the accuracy, stability, and safety of anesthesia depth control, while reducing clinical workload.
