AI Technical Summary

Technical Problem

In existing technologies, it is difficult for a single person to inject local anesthetic during ultrasound-guided nerve block anesthesia, requiring the assistance of an assistant, which makes the operation time-consuming and laborious, and has poor practicality.

Method used

A single-person injection drug delivery aid device for nerve block needles was designed, including a drug storage structure, a piston structure, and a drug delivery structure. The piston structure is used for back-pull detection and local anesthetic drug injection to ensure that no blood is injected before injection, thus enabling single-person operation.

Benefits of technology

It improves the practicality of single-person injection of nerve block needles, simplifies the operation process, reduces reliance on assistants, and improves operation efficiency.
