Clinical Summary: The Medela Invia Liberty (REF 087.0003) is a portable, electronically controlled Negative Pressure Wound Therapy (NPWT) pump that delivers continuous or intermittent sub-atmospheric pressure between -40 mmHg and -200 mmHg via single-use 300 mL or 800 mL canisters. The device uses a patented dual-lumen feedback technology that dynamically adjusts airflow to fluid viscosity, supporting consistent therapeutic pressure at the wound bed. It is indicated for acute, chronic, sub-acute, dehisced, traumatic, and partial-thickness wounds, including pressure ulcers, diabetic foot ulcers, venous insufficiency ulcers, flaps, and grafts.

Product Overview

The Medela Invia Liberty NPWT Pump System (REF 087.0003) is a clinically validated negative pressure wound therapy device manufactured under ISO 13485 quality management standards by Medela AG, Switzerland. Designed for both inpatient and outpatient use, the unit weighs approximately 0.4 kg and integrates an internal lithium-ion battery providing up to 14 hours of mobile therapy, enabling early ambulation and home-based wound management protocols.

The pump implements Medela's patented dual-lumen tubing with electronic feedback control. The system continuously samples pressure at the wound interface and modulates airflow according to exudate viscosity and volume, sustaining the prescribed therapeutic pressure while reducing canister change frequency. Eight preset pressure levels and dual therapy modes (constant and intermittent) allow clinicians to align therapy to International Consensus on NPWT recommendations and individual wound trajectory.

Clinical Indications

  • Acute, sub-acute, dehisced and traumatic wounds where exudate management and granulation are required
  • Stage III and Stage IV pressure injuries refractory to standard moist wound care
  • Diabetic foot ulcers (Wagner Grade 2 and above) following adequate debridement
  • Lower extremity venous insufficiency and arterial ulcers as adjunct to compression and revascularisation
  • Surgical incisional wounds at high risk of dehiscence (incisional NPWT)
  • Bolster therapy over split-thickness skin grafts and meshed grafts to improve graft take

Frequently Asked Questions

Why is -125 mmHg the default therapy pressure?
The international NPWT consensus and the original Argenta and Morykwas studies identified -125 mmHg as the pressure at which microvascular blood flow, granulation tissue formation, and exudate removal are optimised in most wound types. The Invia Liberty allows titration down to -40 mmHg for fragile tissue, ischaemic limbs, or paediatric use.

How does the dual-lumen feedback technology differ from single-lumen NPWT pumps?
A second lumen continuously transmits pressure data from the wound site back to the pump. The microcontroller adjusts airflow to compensate for viscosity changes in exudate and to detect kinks or leaks early, supporting more consistent therapeutic pressure than open-loop single-lumen systems.

What dressing kits are compatible with the Invia Liberty?
The pump operates with Medela Invia foam and gauze dressing kits, the Avance Solo conduits, and standard Y-connectors. Selection depends on wound geometry, exudate level, and tunnelling. Refer to the Medela Invia Liberty Instructions for Use for the current compatibility list.

Is this device suitable for home-based wound therapy in Singapore?
Yes. The 14-hour battery, integrated carry strap and quiet operation make the Invia Liberty appropriate for community nursing and home care models supported by HSA-registered medical device suppliers. emis.asia provides delivery, training, and consumable resupply across Singapore.

What regulatory clearances does the Invia Liberty hold?
The system carries CE Mark under EU MDR 2017/745, FDA 510(k) clearance for negative pressure wound therapy, and is manufactured under ISO 13485 certification. It is registered with the Singapore Health Sciences Authority (HSA) for clinical and home use.
