Abstract: A system for applying external compression to a limb of a user via a system of actuated barrels with compression elements. The system may include a motor, a brake configured to selectively restrict the rotation of different barrels, and a controller configured to operate the brake and motor at different periods of time during use. Sensors may be included, which are coupled to a controller, which, based on sensor data, dictates the timing and degree of compression by controlling the braking system and applied motor current.

Abstract: Embodiments relate to devices, systems and methods of assisting blood flow return to the heart from a limb for fluid responsiveness and limb warming. The device comprising a wearable garment (115) and a compression apparatus (110) embedded in the garment (115) for applying an external compression according to a compression sequence to a muscle of a limb of a user based on real-time measurements during surgery.

The device comprising a wearable garment (115) and a compression apparatus (110) embedded in the garment (115) for applying an external compression according to a compression sequence to a muscle of a limb of a user based on real-time measurements regarding a cardiac cycle having a diastolic phase and systolic of the user and real-time measurements of muscle activity. The compression sequence is synchronized to comment when both the local blood flow at the limb is in the diastolic phase and the muscle is in a non-contracted state.

Abstract: Embodiments relate to devices, systems and methods of assisting blood flow return to the heart from a limb. The device comprising a wearable garment and a compression apparatus embedded in the garment for applying an external compression to a limb of a user and at least one of a processor or a controller configured to control the compression apparatus to apply the external compression, according to a compression sequence, to a muscle of the limb of the user based on real-time measurements regarding a cardiac cycle having a diastolic phase and systolic phase of the user and real-time measurements of muscle activity. The compression sequence is synchronized to commence when both a local blood flow at the limb is in the diastolic phase and the muscle is in a non-contracted state.
