IV cannula
An IV cannula is a short, flexible plastic catheter placed over a needle into a peripheral vein so fluids and medicines can be given over several days. It is used in wards, emergency departments, theatres and clinics.
Common types
- Standard IV cannula with injection port: has a valved side port for giving bolus injections.
- IV cannula without port: a simpler design with only the luer connection.
- Safety IV cannula: a mechanism covers the needle tip after withdrawal to reduce needlestick injuries.
- Closed system IV catheter: integrated extension tubing and blood control to limit blood exposure.
- Pen-type cannula: a slim design with a straight grip, often used for small veins.

Documents to ask for
Buyers usually ask for CE marking under the EU MDR or local registration, ISO 13485 for the maker, ISO 10555-5 for over-needle peripheral catheters, and sterilisation validation to ISO 11135 or ISO 11137.
Certificates and registrations belong to the product and its manufacturer. We check them with you against the rules of your market before any order.
What is the difference between FEP and PUR catheters?
FEP (fluorinated ethylene propylene) is a firmer material that keeps its shape during insertion. PUR (polyurethane) softens at body temperature, which some clinicians prefer for longer dwell times. Both are widely used.
