V-Sets®
V-Sets® are designed around a large bore, fast flow gravity fed infusions line to which any standard giving set may be attached. This line has an anti-reflux valve and includes a unique non-kink design, allowing fixing of the V-Set® to the patient's limb with a 180 degrees loop without fear of obstruction. V-Sets® are intravenous connectors for hospitals. They are available as 2 or 3 lumen sets.Another feature of the V-Set® is that there is no common space in the device as such there is no risk of underdosing (any common space acts as reservoir under slow drip rates of infusion fluid). Likewise there is no risk of inadvertent bolus (increasing drip rate flushes an overdose from the common space to the patient). At 1ml per hour even half a milliliter of common space will predispose to 30 times the dose to be delivered in 1 minute if flushed (a 3000% error in mg/min).
V-Set® Features:
- No common space.
- Anti-kinking spring on main line.
- No drug absorption.
- Maintains pump accuracy.
- Double or triple access available.
- Compatible with most common IV fittings.
- Also available with long lines (2.1m)
- Variety of configurations/valves available
Each line is fitted with a valve which can be either an anti-reflux valve or a one way valve. Both valves prevent fluid flowing in the reverse direction but the anti-reflux valve opens under lower pressure thus allowing fluid to flow when connected to the gravity line.
