CAUTIONS
The following statements describe medical conditions that may require special care for
the safe and effective use of the Invia Wound Therapy.
– Patients at high risk for bleeding and hemorrhage.
– Patients taking anticoagulants or platelet aggregation inhibitors, or in patients
experiencing active bleeding or difficult wound hemostasis.
– Wounds that involve a fistula.
– Using Invia Wound Therapy in close proximity to blood vessels and organs or
exposed organs, vessels, nerves, tendons, or ligaments. Provide necessary
protection of all vessels and organs using a protective barrier.
– Patients with a history of vascular anastomosis or friable, irradiated, sutured or
infected blood vessels.
– Use near vagus nerve (bradycardia) or use on patients with a history of spinal cord
injury (stimulation of sympathetic nervous system).
– Circumferential dressing application.
Incorrect use may cause pain and injury to the patient. Excessive negative pressure,
a too tight adhesive cover dressing, or an infection of the wound may cause pain to
the patient. In either case, the dressing must be removed and the wound assessed.
The patient should be monitored regularly according to physician instructions and
facility guidelines to monitor patient comfort, therapy compliance and signs of wound
infection.
Do not use a Invia Liberty canister or tubing if the sterile packaging is damaged.
The Negative Pressure Wound Therapy must be used 24 hours per day without
interruption. If the pump is stopped for more than the time frames shown below, the
dressing must be changed and therapy restarted.
Gauze dressing: Change dressing if the pump has stopped for more than 24 hours.
Foam dressing: Change dressing if the pump has stopped for more than 2 hours.
Consider the patient's size and weight when prescribing this device.
Consider mode of therapy – intermittent versus continuous.
