1results about How to "Avoid imprecise" patented technology

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.
