Provein Safe 18G IV Cannula

The Provein Safe 18G IV Cannula is the standard peripheral venous access device for routine adult infusions across UK hospitals and healthcare facilities. With a flow rate of 80-130 ml/min, this green-coded cannula strikes the optimal balance between rapid fluid delivery and patient comfort, making it the go-to choice for emergency departments, acute care wards, and surgical environments. Manufactured by LARS Medicare, a family-run medical device company with over 20 years of ISO 13485-certified manufacturing excellence, the Provein Safe 18G combines clinical performance with integrated safety features to protect healthcare professionals from needlestick injuries.​​ Key Clinical Applications Routine hospital infusions and medication administration Blood transfusions (packed red blood cells and blood products) Emergency fluid resuscitation (moderate-to-high flow requirements) Perioperative vascular access for surgical procedures Contrast medium administration for medical imaging Acute care ward infusion therapy Technical Specifications Specification Details Gauge Size 18G (1.2mm outer diameter) Colour Coding Green (international standard) Catheter Material PTFE (Polytetrafluoroethylene) – biocompatible, ultra-smooth Needle Material Medical-grade stainless steel, precision-ground bevel Catheter Length 45mm (standard peripheral insertion) Maximum Flow Rate ~80-130 ml/min (standard high-flow access)​ Safety Mechanism Integrated one-handed needle safety device Design Features Flexible wings, injection port for secondary access Sterility ETO sterilised, individually sealed packaging​ Latex Status Latex-free (hypoallergenic) Design Features & Clinical Benefits PTFE Catheter Technology The Provein Safe 18G utilises PTFE catheter material, the gold standard for biocompatibility and ultra-smooth insertion. PTFE’s low-friction coefficient significantly reduces vascular trauma during advancement and minimises thrombophlebitis risk during extended catheter dwell time, particularly important for patients requiring 48-72 hours of continuous venous access.​ Integrated Safety Mechanism One-handed needle safety activation shields the sharp needle immediately after catheter insertion, reducing needlestick injury risk by over 80% compared to conventional cannulas. For nursing and medical staff performing multiple cannulations daily, this feature provides essential protection against occupational exposure to bloodborne pathogens.​ Clear Flashback Chamber Transparent flashback chamber provides immediate visual confirmation of successful venipuncture, reducing vessel trauma from repeated insertion attempts and improving first-attempt success rates. In busy acute care environments where efficient vascular access matters for patient flow and comfort, reliable flashback visibility supports clinical confidence.​ Flexible Wings & Injection Port Bilateral stabilisation wings provide ergonomic handling during insertion and secure fixation with medical tape, preventing catheter migration during patient movement or repositioning. The integrated injection port allows secondary medication administration (antibiotics, analgesics) without interrupting primary infusion therapy, essential for complex medication regimens.​ When to Choose 18G vs. Other Gauges 18G is optimal when:​ Routine adult infusions requiring reliable moderate-to-high flow rates Blood transfusions in non-emergency scenarios (80-130 ml/min sufficient) Emergency fluid resuscitation where veins accommodate 18G comfortably Standard hospital ward infusion therapy Contrast medium administration for CT or MRI imaging Perioperative access for routine surgical procedures Choose 16G or 14G instead when:​ Emergency trauma requiring maximum flow rates (200-250 ml/min) Massive transfusion protocols for severe haemorrhage Rapid resuscitation where every ml/min matters clinically Choose 20G or 22G instead when:​ Patient has smaller peripheral veins (elderly, paediatric) Lower flow rates (60-70 ml/min) are clinically adequate Long-term venous access where smaller gauge reduces phlebitis risk Patient comfort prioritised over flow rate Why 18G is the Most Common Hospital Gauge The 18G cannula has become the standard across UK hospitals for a compelling reason: versatility. While not as fast as 16G for emergency situations, its 80-130 ml/min flow rate is sufficient for routine infusions, medication delivery, and most blood transfusions. For nurses and doctors, this means familiarising with one primary gauge for routine practice, with larger gauges (14G, 16G) reserved for emergencies and smaller gauges (20G-26G) for special populations. This efficiency, combined with superior patient comfort compared to larger gauges in routine insertions, makes 18G the default choice across NHS wards.​ Manufactured by LARS Medicare: Family-Trusted Quality Since 2005 LARS Medicare Pvt.
