AI Technical Summary

Technical Problem

Traditional ZIM zoning relies on ultrasound scanning equipment imaging and the experience and judgment of medical staff, which leads to inaccurate zoning and increases the risk of puncture failure and complications.

Method used

A positioning ruler based on PICC ultrasound-guided puncture ZIM partitioning is designed, including a first positioning ruler and a second positioning ruler. The transparent plate is divided into a red lower section, a green middle section, and a yellow upper section. Combined with a sliding plate, an adjusting rod, and a magnetic plate, it provides intuitive area division and arm restriction, reducing human error.

Benefits of technology

It improves the accuracy and efficiency of ZIM partitioning, reduces the risk of puncture failure and complications, simplifies the procedure, and reduces reliance on ultrasound scanning and subjective judgment.

Abstract

This utility model belongs to the field of medical devices, and particularly relates to a positioning ruler for ZIM partitioning based on PICC ultrasound-guided puncture. It includes a first positioning ruler, a second positioning ruler, a fixing plate, a limiting plate, and a sliding plate. The first and second positioning rulers, with identical structures, are arranged side-by-side and in a mutually opposing state. The fixing plate is fixed to one end of the first positioning ruler, and the limiting plate is fixed to the front of the fixing plate, with a vertical plate at one end. The sliding plate is slidably mounted on the limiting plate and located behind the vertical plate. By setting precisely graduated first and second positioning rulers on the positioning ruler and dividing the transparent plate into three areas corresponding to the ZIM partition, the originally abstract ZIM partition is presented intuitively. Medical personnel only need to instruct the patient to place their arm on the limiting plate to quickly and accurately determine the boundaries of each area, reducing reliance on ultrasound scanning and subjective judgment, improving operational efficiency and standardization, and reducing human error.
