The invention relates to the technical field of automatic
drug delivery control, in particular to a
drug delivery control method and
system for a surgical postoperative analgesia pump, and the method comprises the following steps: obtaining a
respiratory rate and a pressing behavior sequence of a patient, recognizing a fluctuation trend and request growth, judging a synchronous
response time period, and adjusting an infusion
rhythm and dosage.
Pressure curve characteristics are analyzed to recognize abnormal operation, emergency infusion is executed in combination with
signal linkage, and a dynamic
drug administration control instruction is generated. According to the method, the severe fluctuation identification is generated by obtaining the continuous
breathing frequency change trend of the patient and combining with
breathing extreme value judgment, the linkage time period mark is formed by matching with sequential change
trend analysis of the request behavior of the patient, and the basic infusion frequency and dosage are adjusted in real time to meet the actual analgesia requirement; an intelligent recognition and quick response mechanism under the dominant physiological state is achieved, the adaptability, safety and timeliness of the analgesia process are enhanced, and the problems of control
lag and judgment blind areas in a fixed parameter mode are effectively relieved.
