No, unless your health care provider advises you otherwise, you will NOT need to be confined to your bed during treatment with the device. ActiveCare®+S.F.T. is designed to prevent the onset of DVT. When a patient has a problem that limits ambulation, ActiveCare®+S.F.T. 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.
