A rigid back member of an automatic mechanical chest compression device is secured to a torso support platform. The torso support platform includes a main support strap immediately below where the rigid back member is secured to the torso support platform, and an upper support strap above where the rigid back member is secured to the torso support platform. The torso support platform tapers towards the top at approximately where a patient's shoulders are located when properly secured to the torso support platform. Additional straps may also be utilized, for example, shoulder straps extend over the shoulders of the patient and are secured to the torso support platform at a point below the patient's armpits, or straps that extend from the tapered section and secure to the automatic mechanical chest compression device.

A compression garment apparatus for a body part of an human and/or animal having a flexible backing, attaching means, a segmented flex frame, and a shape memory alloy on the segmented flex frame. The shape memory alloy can be connected to two terminals on the frame forming a circuit. A controller can be connected to the terminals applying current to the shape memory alloy at defined intervals providing intermittent, sequenced, or continuous compression therapy.

Some embodiments relate to compositions for active compression devices and related methods. In some embodiments, a composition for an active compression device comprises an electro-active polymer film. In some embodiments, the electro-active polymer film comprises at least one polymer and at least one additive.

A system and method for determining CPR induced chest compression depth using two sensors while accounting for different orientations of the two sensors. The system may include a first motion sensor operable to generate motion signals corresponding to motion in a first coordinate frame defined by a first set of axes and a second motion sensor operable to generate motion signals corresponding to motion in a second coordinate frame defined by a second set of axes and a control system operable to receive the motion signals from the first motion sensor and the second motion sensor, rotate the motion signals from the first motion sensor into the second coordinate frame to obtain rotated motion signals corresponding to the motion signals from the first motion sensor, and combine the rotated motion signals with the motion signals from the second motion sensor to generate an output indicative of said displacement.

An ottoman includes a support base, a reversible footrest that is removably supported in the support base and houses an electrically powered massager, and a compression band that is attached to the reversible footrest and extends over a top or bottom side of the reversible footrest, with the compression band being configured to compress a foot or feet of a user between the compression band and the reversible footrest. The reversible footrest has a first orientation in which the compression band is exposed outside the support base and a second orientation in which the compression band is stowed in the support base. The electrically powered massager is operable when the reversible footrest is in both the first orientation and in the second orientation.

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.

Wearable devices and methods for preventing and treating carpal tunnel syndrome or DeQuervain's syndrome. The wearable device may include a wrist contact portion for receiving a user's forearm, a stretching mechanism configured to apply opposing forces to a first contact portion and a second contact portion to stretch the user's underlying tissue, the first and second contact portions configured to contact the user's forearm, and one or more straps configured to adjust the compressive force being applied to the user's forearm by the first and second contact portions. The first contact portion may be configured to apply a compressive force to the user's forearm at a first location. The second contact portion may be configured to apply a compressive force to the user's forearm at a second location different than the first location.

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.

This invention is directed to a wearable device to be worn around a pelvis of an object, comprising: a first compressive element configured to embrace the ASIS and PSIS anatomical structures of the object pelvis; a second compressive element configure to embrace the Ischial Tuberosities and Greater Trochanter anatomical structures of the object pelvis; at least one sensor for sensing pelvic rotation asymmetry of the object in real time during stride motion; at least two actuators for applying a corrective pressure on at least one PSIS and/or Ischial Tuberosities in real time during said stride motion so as to balance a measured pelvis rotation asymmetry of the object the pelvis rotation; and a control unit configured and operable to receive data in real time from said at least two sensors during the stride motion, calculate the pelvis symmetry based on the data received, and activate at least one of said actuators to apply a corrective pressure upon recognition of a pelvis rotation asymmetry.

An intelligent compression device for controllable compression. The compression device includes a compressible body and a microprocessor. The compressible body encircles a limb of a user and includes an elastomer layer and an activation layer. The elastomer layer includes voxelated liquid crystal elastomers that contract in response to a stimulus. The activation element, which is positioned proximate to the elastomer layer, supplies the stimulus. The microprocessor actuates at least a portion of the activation element layer.
