Method of use

Used to break the vacuum in rigid containers to allow fluid flow. The fluid container and giving set is prepared for use.The sheath of the air inlet needle is removed and the needle inserted into the injection port (ports can be latex or non-latex) of the rigid container (such as a glass bottle containing IV fluid). The vacuum within the container draws air through the filter and into the container to allow the container to drain into a primary solution set, for example. The filter prevents contamination of the contents of the container. The air inlet needle remains in situ for the duration of use of the fluid container.

Please note: usage of this product is generally in decline due to the reduced use of rigid containers for IV fluid administration and an effort to reduce the risk of needlestick injuries. Simple fluid administration sets now have an air inlet valve incorporated into the spike/top chamber assembly. However, they are still used with unvented administration sets and blood giving sets. Increased use in Theatres has also been reported following the introduction of IV paracetamol in 50 and 100 ml glass bottles.
