Calibrated 2-layer compression system – High compression

KTwo is an innovative two layer compression system, designed to ensure even distribution of pressure between two dynamic bandages. KTwo applies the effective therapeutic pressure required to treat active or healed venous leg ulcers and associated symptoms along with severe oedema in chronic venous insufficiency. Irrespective of leg shape, KTwo provides the correct level of pressure from the very first application thanks to its specific etalonnage system (pressure indicator).

Composition

The KTwo compression system consists of two separate dynamic bandages:

KTwo combines the properties of the 2 bandages and forms an innovative two-layer compression system that guarantees:

• The pressure required to effectively treat leg ulcers, irrespective of ankle size, due to the different kits available depending on ankle circumference.
• Maintenance of this level of pressure both day and night for up to 7 days if necessary.
• A significant massage effect when mobile as a result of moderate pressure at rest and high pressure on walking.
• The correct pressure level from the very first application, with minimal training, due to the etalonnage (pressure indicators) printed on every bandage.
• Clinically proven efficacy on the healing of leg ulcers.
• A significant reduction in associated venous oedema.

K Two also provides the patient with the ability to wear normal footwear and good level of comfort, both day and night, for an acceptable quality of life.

K Tech and K Press are specifically designed to be used together

K Tech provides 80% of the overall bandage pressure (between 30 – 35 mmHg).

K Press provides the additional pressure required to obtain an average pressure of 40mmHg, the recommended therapeutic pressure to heal venous leg ulcers

Indication

KTwo is indicated for the treatment of venous leg ulcers and the reduction of chronic venous oedema.

Contra-indications

- High-level compression is contra-indicated in patients suffering from an arterial condition (arterial or predominantly arterial ulcer; known or suspected arterial disease). KTwo is not recommended when the ankle-brachial pressure index (ABPI), measured by Doppler ultrasound, is below 0.8.

- Patients potentially allergic to any of the components (especially to latex).

Precautions of use

- Before prescribing KTwo, it is necessary to perform a Doppler ultrasound assessment to check that the ABPI is greater than 0.8;

- In the event of diabetes, heart failure or advanced microvascular disease, KTwo should only be used following medical advice, with close monitoring and after appropriate treatment.

- The efficacy of KTwo has been tested and validated for the simultaneous application of K Tech and K Press.

- If any difficulties arise, consult your clinician.

Etalonnage

Both bandage layers, K Tech and K Press, have an etalonnage (pressure indicator) designed to aid application and ensure the correct pressurel level is applied every time. Each bandage is printed with an ellipse which becomes a circle when the correct stretch is reached. During application, the etalonnage marks should just be covered to obtain the correct overlap.

The PresSure System makes it possible to obtain :

• The correct bandage tension
• The correct number of layers

Optimal therapeutic pressure is achieved when the correct stretch and the correct overlap have been obtained.

The K Two "PresSure System" ensures the correct pressure is easily achieved from the very first application.

Application Technique

Before applying the bandages:

• Doppler the patient to ensure the ABPI is greater than 0.8.
• Assess the limb-shape to identify any abnormalities and potential pressure areas.
• Check the ankle circumference to ensure the appropriate kit size is chosen (ie: 18-25 cm or 25-32 cm).
• If there is a wound presented, apply an appropriate dressing.
• Before application, position the foot at 90 degrees (“toes to nose”).
• The bandage is best applied first thing in the morning or after the leg has been elevated for half an hour to reduce oedema.

Mode of application:

For the application of the K Two Compression Bandage System for Venous Leg Ulcers and Chronic Venous (Lymphovenous) Oedema (read more...)

Important:

• The etalonnage on the bandages indicates when the correct therapeutic pressure has been reached. The bandages have been correctly applied to the leg when each ellipse becomes a circle and when the etalonnage is just covered.
• Always remove any excess bandage: do not over-wrap the leg.
• K Two is recommended for a maximum of 7 days.
• The two bandages making up the K Two system are designed to be worn day and night, throughout the period between local dressing changes.
