Why Constant Vacuum Matters in Wound Drainage: A Smarter Alternative to Traditional Systems

When it comes to post-operative wound care, control is everything.

Surgeons and nurses know that effective drainage reduces complications like seroma formation and delayed healing. But not all wound drainage systems offer the same level of performance — especially when it comes to maintaining consistent vacuum levels.

The Problem with Traditional Mechanical Drains

Most mechanical drainage systems (like bulb or accordion-style drains) rely on physical compression to generate negative pressure. As they expand over time and collect fluid, their vacuum strength rapidly decreases — and it’s impossible to know what level of suction is still being applied.

Once fully expanded, these systems offer no active vacuum, which can result in:

• Fluid pooling at the wound site

• Reduced drainage effectiveness

And since they offer no real-time feedback or control, clinicians are left guessing.

VariVac™: Reliable, Constant Low Vacuum — Always

VariVac™ solves this problem with a battery-powered system that delivers constant, adjustable vacuum throughout the drainage period.

• Simply turn the dial to select one of three preset vacuum levels

• The system maintains consistent suction regardless of how much fluid is collected

• No guessing, no loss of performance — just reliable drainage

This consistent vacuum improves fluid removal and helps keep wound sites managed with precision.

Designed by Clinicians, for Clinicians

VariVac™ was developed in collaboration with Australian healthcare professionals who were frustrated by the limitations of passive drainage. The result is a smarter, safer, and more predictable solution for post-operative fluid management.

Whether you're managing surgical sites, deep tissue drains, or high-output wounds, VariVac™ gives you clarity, control, and confidence.
