I.V. Cannula
I.V. Cannulae is a kind of catheter that can be used to insert in a
patient's vein in order to give anesthesia, medicine or other solutions for
intermittent drug therapy/infusion or multiple fluid infusion. It prevents
the needle from being accidentally dislodged and minimizes its exposure to
patient tampering
The catheter is made of Virgin P.T.F.E. (Ply Tetra Fluro Ethylene), one of
the most biocompatible materials known to man or else Teflon or
polyurethane. The Japanese steel is often preferred for the cannula. It is a
triple point needle for painless insertion.
Other parts of the IV cannula are:
Siliconised needle point - for smoother penetration and rapid
closure after needle withdrawal.
Needle Cover - protects the needle point during handling. The extra
thin walled needle has a needle hub with a large and clear flash back
chamber.
Injection Port With a Snap Fit Protection Cap - allows injection of
medicine during infusion.
Flexible Grooved Wings - provide an angle between the plane of the
wings and catheter.
Threaded Stopper With Lock is used to stop the blood spillage after
infusion is stopped.
