    摘要: An active compression device includes a textile wrap configured to be secured around a waist of a user. Additionally, the active compression device includes a controller assembly disposed within the textile wrap, wherein the controller assembly includes one or more shape memory wires configured to apply compression to the user's back in response to actuation of the one or more shape memory wires. The controller assembly also includes processing circuitry configured to receive a selection of a predetermined compression profile, and in response to receiving the selection of the predetermined compression profile, activate a predetermined pattern of compressions corresponding to the selected predetermined compression profile.

    摘要: A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises one or more shape-memory wires integrated into an article of clothing and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, a pre-tensioning apparatus in the form of a bungee cord associated with each shape memory wire, and a micro-processor based controller for selectively actuating the one or more shape memory wire to reduce the length of the shape memory wire to thereby apply pressure to the wearer's body.

    摘要: A compression device particularly suited for DVT prophylaxis includes a disposable wrap and a re-usable controller removably mounted on the wrap to apply a tensioning force to the wrap when it is encircling the limb of a patient. The wrap includes an RF chip with a unique identifier and the controller includes an RF sensor and processor to authenticate the wrap before commencing a compression cycle. A kiosk is provided for storing a plurality of wraps for use by patients and a plurality of controllers to be used with any of the wraps. The processor of each controller can control an electric motor in the controller to tighten and loosen the wrap according to a compression protocol between a pre-tension compression force and maximum compression force. The amount of movement of the wrap changes as the patient's physiology changes while maintaining the pre-tension and maximum compression forces.

    摘要: A lace-tightening device for a shoe lace in a shoe includes a rotating cam within a housing disposed within the shoe. The cam is connected to the opposite ends of the shoe lace and includes an outer surface for receiving the shoe lace as the cam rotates to pull the lace. A ratchet arm is slidably disposed within the housing and includes linear teeth arranged to engage the teeth of a driven gear as the ratchet arm translates in a linear direction, to rotate the gear in the one direction. The driven gear is part of a gear train connected to the cam to rotate the cam. The ratchet arm is pulled by at least one shape memory alloy (SMA) wire attached to a controller that is configured to execute a power cycle to energize and deenergize the SMA wire to thereby sequentially translate the ratchet arm in the linear direction, and ultimately to incrementally pull and tighten the shoe lace.

    摘要: A lace-tightening device for a shoe lace in a shoe comprises a rotating cam within a housing disposed within the shoe. The cam is connected to the opposite ends of the shoe lace and includes an outer surface for receiving the shoe lace as the cam rotates to pull the lace. A driven gear disposed is rotatably coupled to the cam through a one-way clutch configured so that rotation of the driven gear in one direction rotates the cam in the one direction, thereby tightening the shoe lace connected to the rotating cam. A ratchet arm is slidably disposed within the housing and includes linear teeth arranged to engage the teeth of the driven gear as the ratchet arm translates in a linear direction. to rotate the gear in the one direction. The ratchet arm is pulled by at least one shape memory alloy (SMA) wire attached at one end to the ratchet arm and at its opposite end to a controller. The controller is configured to execute a power cycle to energize and deenergize the SMA wire so that the wire sequentially shrinks and returns to its original length to thereby sequentially translate the ratchet arm in the linear direction, and ultimately to incrementally pull and tighten the shoe lace. The controller repeats the cycle a number of times until the lace reaches a tightness desired by the user.
