AI Technical Summary

Technical Problem

In the existing technology, the timed and quantitative drug delivery method in the treatment of heart failure cannot accurately match the actual needs of patients, resulting in dosing intervals that may be too long or too short, and poor accuracy.

Method used

The intelligent drug delivery system monitors the patient's central venous pressure in real time through a central venous pressure measuring device and uses an MCU control unit to control a motor-driven drug release pump to achieve automatic quantitative drug delivery, including precise control of the peristaltic pump and lead screw assembly.

Benefits of technology

It enables automatic drug administration based on real-time changes in the patient's central venous pressure, improving the accuracy of drug administration timing and reducing the workload of medical staff.

Abstract

The embodiment of the utility model provides an intelligent drug delivery system. The intelligent drug delivery system comprises an MCU (Microprogrammed Control Unit), a motor, a drug release pump, a drug storage device and a central venous pressure measuring device, the motor is electrically connected with the MCU control unit, and the output end of the motor is connected with the drug release pump; the liquid medicine input end of the medicine release pump is communicated with the medicine storage device, and the liquid medicine output end of the medicine release pump is communicated with an intravenous injection catheter for intravenous drip of a patient; the signal output end of the central venous pressure measuring device is electrically connected with the MCU through the pressure transmitter. According to the technical scheme, the central venous pressure of a patient is obtained in real time and fed back to the MCU control unit, when the measured value reaches the preset value, the MCU control unit sends a signal to the motor so as to drive the drug release pump to be started and send out a preset amount of drug, and therefore automatic drug delivery is achieved. According to the technical scheme, the dosing opportunity is more accurate, the health of a patient is better facilitated, and meanwhile the working intensity of medical staff is relieved.
