Frequently Asked Questions

Deep Vein Thrombosis (DVT) is a blood clot that forms in a vein, deep in the tissues of the lower extremity. Blood clots commonly form in the deep veins of the calf or thigh, following total joint replacement or prolonged immobilization if not treated prophylactically. Left untreated, these clots can cause disability or become life threatening if they become mobile (pulmonary embolism) and travel throughout the body.

The ActiveCare+S.F.T. System is a safe and highly effective way to improve blood flow in the veins and to help prevent DVT. The system delivers continuous enhanced circulation therapy (C.E.C.T.) to the lower extremities. It works by applying intermittent, sequential compression to the legs in a systematic pattern, increasing the speed of blood flow in the veins and reducing the risk of clot formation.

The ActiveCare+S.F.T. System is the ONLY device that syncs the compressions to the patient’s individual venous phasic flow and is clinically proven to be effective in DVT prevention. Unlike standard IPC, The ActiveCare+S.F.T. System does not require anticoagulants intake throughout the treatment period.

No, unless your health care provider advises you otherwise, you will NOT need to be confined to your bed during treatment with the device. The ActiveCare+S.F.T. System is designed to prevent the onset of DVT. When a patient has a problem that limits ambulation, The ActiveCare+S.F.T. System enables the body to simulate venous flow as in normal walking activities. This unique battery-powered system is especially lightweight, portable and comfortable to wear, so that you can disconnect the device from the mains supply for up to 5 hours. You can take the device with you wherever you go: Walk around, sit outside, and even travel. In fact, you will be free to do most normal activities without restriction. Be careful to follow all of your physician’s instructions regarding post-surgical care.

You may use the device’s carrying strap in order to wear the device. The strap may be worn over the shoulder or diagonally across the shoulder, to prevent slipping or discomfort. You may also adjust the carrying strap and use it to hang the device over a cart or bed side bar. The device should always be worn together with the leg sleeves. The sleeves should be worn directly on the skin and allow for two fingers to be placed both proximally and distally. If more or less can be placed then it is incorrect.

The batteries in the device recharge themselves from the moment the mains to the device is connected to the power supply. If the battery level indicator displays “Battery Low”, all you need to do is re-connect the device to the power supply until it is recharged. Once the batteries are fully charged, a message on the device screen will display that the battery charging has been completed. The device may be used while the batteries are charging.

The ActiveCare+S.F.T. System can detect problems and will prompt you to take possible corrective action. Please follow the instructions and Help Menu on your Error Screen or on the PATIENT MANUAL. If any problem persists or cannot be solved, please contact your local ActiveCare provider.

Low battery level (battery lasts up to 5 hours): Re-connect the device to the power supply and recharge the battery.

Air blockage (usually due to a kink in the tubing): Make sure the air can move freely through the tubing and that there are no kinks or blockages. In case of Air blockage please contact your service provider.

Air Leakage (usually due to poorly connected tubing): Make sure the tubing is well connected to the sleeves and to the device.

The device is equipped with an easy to read LCD screen, to assist you in keeping track of your personal usage and to closely follow your doctor’s instructions.

The longer you use the device, the better. ActiveCare®+S.F.T is designed to be comfortably used on a 24-hour basis and should be worn for at least 20 hours per day. You may use the device during normal daily activities. You may take breaks from using the device for no longer than 30 minutes at a time.

We have developed The ActiveCare +S.F.T. System to be an especially quiet device so that during normal operation the device is not noisy. Unless an error message appears on the device, the device should be working properly if you feel the sleeves filling up with air and then released a few seconds later.

The device is sensitive to both heat and water. It should not be covered by pillows or blankets or taken into a wet or steamy environment, such as in the shower, swimming pool or rain. Make sure it is used in temperatures between -10°C to +30°C /14°F to +86°F.

The device is supplied to you cleaned and disinfected. There is no need to clean it again. However, if for any reason you feel it needs additional cleaning, follow these steps:

  1. Turn the device off and unplug the AC/DC adapter.
  2. Gently wipe the device with a soft cloth moistened with 70% ethanol (alcohol) solution. Allow appropriate drying time before turning the device on.
  3. Wipe the carrying straps and the extension tube exterior with a damp cloth using 70% ethanol or soap and water. Do not immerse the extension tubes in liquid.

CAUTION: Do not wash the sleeves, as this might damage the sleeves or the device.

You must only use the ActiveCare+S.F.T. charger that you received together with the device. Make sure to take the adapter with you on the day of your discharge or when you are traveling.
