Intended Use

The Invia Ease Negative Pressure Wound Therapy (NPWT) system is indicated for patients who would benefit from a suction device (Negative Pressure Wound Therapy) as when used on open wounds it creates an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and by removing exudates and infectious material. When used on closed surgical incisions, the Invia Ease NPWT System is also intended to manage the environment of surgical incisions that continue to drain following sutured or stapled closure by maintaining a closed environment and removing exudate via the application of Negative Pressure Wound Therapy (NPWT). The Invia Ease NPWT system is intended for use in acute, extended and home care settings.

Device Story

Invia Ease NPWT System is a portable, reusable suction pump for negative pressure wound therapy. It applies controlled negative pressure to wounds to promote healing by removing exudate and infectious material, reducing edema, and preparing the wound bed. Used in acute, extended, and home care settings by clinicians or patients. Input consists of vacuum pressure settings (continuous or intermittent) managed via a touchscreen interface. The device monitors pressure via an electric sensor and provides visual/acoustic feedback for alarms (e.g., blockage, canister full, low battery). It utilizes an adaptive air flush mechanism to maintain therapy. Output is the maintenance of a closed, negative-pressure environment at the wound site. Benefits include improved wound bed preparation and management of surgical incision drainage. The device is used with specific Medela canisters and dressings.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical bench testing, including vacuum performance, pump endurance, battery run-time, noise, and IP22 ingress protection testing. Biocompatibility testing (cytotoxicity, intracutaneous reactivity, sensitization) performed per ISO 10993 standards. Usability testing conducted per human factors guidance.

Technological Characteristics

Powered suction pump; Class II; IP22 rated. Materials: Canister and tubing tested for biocompatibility (ISO 10993). Energy: Internal 7.2V 5000mAh Li-Ion battery or external AC/DC adapter. Vacuum range: -40 to -200 mmHg. Connectivity: Standalone. Software: Embedded, moderate level of concern. Sterilization: Provided sterile (dressings). Features: Touchscreen interface, electric vacuum sensor, adaptive air flush, acoustic/visual alarm system per IEC 60601-1-8.

Indications for Use

Indicated for adult patients requiring negative pressure wound therapy for acute, subacute, chronic, dehisced, pressure, diabetic/neuropathic, venous insufficiency, or traumatic wounds, partial thickness burns, flaps, grafts, or closed surgical incisions. Contraindicated for necrotic tissue with eschar, untreated osteomyelitis, non-enteric/unexplored fistulas, malignancy (except palliative), exposed vasculature, nerves, anastomotic sites, or organs.

Regulatory Classification

Identification

A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. The device may be used during surgery in the operating room or at the patient's bedside. The device may include a microbial filter.
