AI Technical Summary

Technical Problem

When the prior art traditional Chinese medicine catheters are disinfected and sterilized in low-temperature plasma sterilizers, the diameter and length of the catheters need to be checked one by one. The measurement speed is slow and the labor intensity is high, which cannot meet the measurement needs of large batches of multi-special catheters.

Method used

A medical catheter measuring tool is designed, including a gauges and a stopper provided with a coaxial line. The gauges are a step shaft structure composed of a mandrel of a designed diameter and a designed length. The gauges are a sphere, flange or sleeve of a hemispherical or sliding suit. Through the coordination of the gauges and the stopper, the inner diameter and length of the catheter can be quickly measured.

Benefits of technology

It realizes rapid, simple and accurate measurement of medical catheters, improves measurement efficiency, reduces labor intensity, and can meet the measurement needs of large batches of multi-special catheters, ensuring the technical requirements of the sterilization process.

Abstract

The utility model relates to a medical catheter measuring fixture, which comprises a go gauge and a no-go gauge which are coaxially arranged, the go gauge is of a stepped shaft structure formed by a group of mandrels with designed diameters and designed lengths, and a shaft shoulder of the stepped shaft formed by the go gauge is a hemispherical no-go gauge. According to the utility model, when the no-go gauge is loaded on the go gauge and the inner diameter of the tube cavity is measured, the go gauge is inserted into the tube cavity and is cut off until the no-go gauge, and if the go gauge can be exposed from the other end of the tube cavity material, a low-temperature plasma sterilizer can be used for disinfection. Measurement is simple, direct and fast.
