AI Technical Summary

Technical Problem

Existing combination caps for infusion containers are prone to loosening of the interface due to movement of the infusion tubing during infusion, affecting the seal and potentially causing air ingress, drug leakage, and contamination, increasing the risk of cross-infection.

Method used

A combined cap consisting of an outer cap, an inner cap, and a gasket is designed. The outer cap is equipped with a fixing mechanism and an anti-shaking mechanism, which fixes the infusion tube by a snap-fit ​​method to ensure that it does not shake during infusion. The inner cap and the outer cap are equipped with a snap-fit ​​mechanism to enhance the sealing performance. The sealing valve is equipped with a warning mark for easy identification of its purpose. The gasket is equipped with uniform puncture parts and claws that cooperate with the limiting groove to ensure the integrity of the sealing structure.

Benefits of technology

It effectively prevents the infusion tubing from shaking, maintains a tight seal, avoids drug leakage and air ingress, improves the stability and safety of the infusion process, reduces the risk of cross-infection, simplifies the operation process, and adapts to the needs of different specifications of infusion tubing.

Abstract

This utility model belongs to the field of medical device technology, and particularly relates to a combination cap for infusion containers; it includes an outer cap, an inner cap, and a gasket disposed between the outer and inner caps; the outer cap is stepped, with multiple sealing valves at its top; the cavity formed by the combination of the outer and inner caps contains several liquid channels, and the gasket is disposed within the liquid channels; the gasket is pressed tightly into the liquid channels by the inner cap; a fixing mechanism is disposed on the outer cap to fix the infusion tubing and prevent it from shaking during use; an anti-shaking mechanism, through a locking mechanism, prevents unnecessary shaking of the infusion tubing during infusion, thereby maintaining a sealing effect. This utility model provides a combination cap for infusion containers that improves sealing performance and prevents loosening of the interface due to shaking of the infusion tubing.
