AI Technical Summary

Technical Problem

Existing external analgesia pumps are susceptible to external forces, which can cause the tubing to detach or be damaged, resulting in unstable drug delivery. Furthermore, they can restrict patients' daily activities and pose significant safety risks.

Method used

Design an implantable analgesia pump, including an infusion tube, placement seat, fixing block, protective cover, locking block and other auxiliary mechanisms. The drug flow rate is adjusted and fixed by adjusting gears and insert rods, and a rubber stopper is used to prevent drug spillage. The pump is fixed to the skin using a patch.

Benefits of technology

It achieves stability and safety in drug delivery, reduces damage to the infusion tubing from external forces, improves the precise control of drug dosage, and enhances patients' freedom of daily activities.
