Why 24G × 0.75" with Blood Control and Passive Safety for Fragile Vein Access

The 24-gauge catheter (0.7mm outer diameter) with 0.75-inch (19mm) length is specifically designed for fragile, small, or difficult veins commonly encountered in pediatric patients, elderly adults with thin-walled vessels, oncology patients with compromised vasculature, and any patient requiring the gentlest possible venous access where larger catheters would cause excessive trauma or insertion failure. The smaller gauge significantly reduces insertion pain and vein trauma while still accommodating maintenance fluids, most IV medications, and blood sampling. The Auto-Guard passive safety mechanism activates automatically upon needle withdrawal without requiring additional clinician action, eliminating human error while protecting healthcare workers from needlestick injuries. BC (Blood Control) technology features an integrated valve that minimizes blood exposure during insertion and connection, maintaining clean sites and reducing blood-borne pathogen exposure risk. The Vialon™ biomaterial softens up to 70% in the vein, conforming to delicate vessel anatomy and reducing mechanical phlebitis for extended dwell time.

Key Features & Benefits

Key Features:

• Latex-free construction for allergy safety
• Single-use, disposable design

Benefits:

• Smallest gauge reduces pain and trauma in fragile veins
• Short length ideal for hand veins and pediatric patients
• Passive safety eliminates human error in needle shielding

• Vialon material extends catheter dwell time
• Appropriate for patients with small or compromised vasculature
• Color coding prevents gauge selection errors
• Latex-free protects sensitive patients and staff
• Universal compatibility simplifies IV setup

Clinical Applications

BD Insyte Auto-Guard BC Pro 24G × 0.75" catheters are appropriate for:

✓ Pediatric IV access (infants, children, adolescents with small veins) ✓ Geriatric patients with fragile, thin-walled veins ✓ Oncology patients with compromised vasculature ✓ Patients requiring gentle venous access (small or fragile veins) ✓ Hand and distal forearm vein access ✓ Patients with difficult IV access requiring smaller gauge ✓ Maintenance fluid therapy and hydration ✓ Continuous medication infusions (antibiotics, analgesics) ✓ Intermittent medication administration ✓ Blood sample collection from peripheral IV lines ✓ Outpatient infusion center treatments ✓ Emergency department stabilization ✓ Hospice and palliative care IV access ✓ Home healthcare IV therapy ✓ Ambulatory patients needing mobility during therapy ✓ Patients requiring extended peripheral IV therapy

Usage & Application

Setup and Insertion:

• Verify IV therapy order and patient identity
• Gather supplies and perform hand hygiene
• Apply tourniquet gently (use minimal pressure for fragile veins)
• Select appropriate vein (hand, distal forearm preferred)
• Clean site with chlorhexidine or alcohol (30-second dry time)
• Insert catheter at shallow angle (10-15 degrees for superficial veins)
• Use slow, controlled motion until blood flash visible
• Lower angle and advance catheter smoothly off needle
• Release tourniquet and withdraw needle (passive safety activates automatically)
• Connect IV tubing or flush gently with saline
• Secure catheter with transparent dressing and strain-relief loop
• Label with date, time, and gauge

Blood Control Technology:

• BC valve automatically controls blood flow during insertion
• Minimizes blood exposure when connecting IV tubing
• Reduces cleanup time and contamination risk
• Protects healthcare workers from blood-borne pathogens

Passive Safety Activation:

• Simply withdraw needle straight back after catheter placement
• Auto-Guard mechanism automatically shields needle
• Audible/tactile click confirms needle locked in safety chamber
• No additional steps required from clinician

Catheter Maintenance:

• Assess site every 4 hours (minimum) for complications
• Flush with 10 mL saline every 8-12 hours if saline lock
• Use gentle, slow flushing technique (small veins sensitive)
• Change transparent dressing every 5-7 days or when compromised
• Monitor closely for infiltration (24G more prone than larger gauges)
• Remove catheter when no longer needed or if complications arise

Special Considerations:

• Pediatric patients: Excellent choice for children; use topical anesthetic and distraction techniques
• Geriatric patients: Ideal for fragile veins; use minimal tourniquet pressure and shallow insertion angle
• Oncology patients: Often only option for compromised vasculature; verify peripheral line appropriate
• Hand placement: More prone to dislodgement; secure well with strain-relief loop
• Flow rate: Lower than larger gauges (13-22 mL/min); not suitable for rapid resuscitation

Flow Rate: Approximately 13-22 mL/min at gravity flow (patient-dependent)
