Calibrated 2-layer compression system – High compression
KTwo is an innovative multi-layer multi-component 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). (read more ...)
Composition
The KTwo compression system consists of two separate dynamic bandages :
| K Tech (the 1st layer) : K Tech is a composite layer formed of wadding and a moderately elastic compression fabric. Composition :
| K Press (the 2nd layer) : K Press, the second bandage, to be applied over K Tech, is a cohesive elastic bandage.
|
Mode of action
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, thanks to the different kits available depending on ankle circumference.
- Maintenance of this level of pressure day and night for 7 days if necessary.
- A significant massage effect on walking thanks to moderate pressure at rest and high pressure on walking.
- The correct pressure dose from the very first application, with no prior training, thanks to the pressure indicators.
- Clinically proven efficacy on the healing of leg ulcers.
- A significant reduction in associated oedema.
A good level of comfort, both day and night, for an acceptable quality of life.
K Tech and K Press are designed to be used together (read more...)
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 doctor.
Etalonnage
Both bandage layers, K Tech and K Press, have an etalonnage (pressure indicator) designed to aid application and show that the bandages have been applied correctly. The two layers are 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 etalonnage makes it simple and easy to apply the correct pressure across both layers with K Tech and K Press, from the very 1st 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, hold 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 :
Assess need for toe to knee or toe to thigh bandaging depending on the indication.
In case of venous leg ulcer: application below the knee using a 10cm width K Two kit (read more...)
In case of venous oedema: application below the knee or on full leg using 8, 10 and 12cm width Ktwo kits (as appropriate) (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.
