In an embodiment, a compression garment can include one or more of a flex frame, a shape memory material, a backing, and a control module. In some variations, the flex frame can include a set of support regions, a set of cutout regions, a set of bridges, one or more terminals, and one or more rotation points. In some variations, the compression garment 100 can further include a fabric sleeve, one or more fasteners, a power module, and/or any other suitable component. The compression garment functions as a compression device (e.g., to improve circulation, enhance muscle recovery, etc.), and can additionally or alternatively function as a passive compression device, a heating and/or cooling device, or perform any other suitable functionality.

An apparatus for generating a rotary reciprocating motion comprises an input shaft which is driven with unidirectional rotation and an output shaft for delivering reciprocating rotary motion. A first magnetic or ferromagnetic ring is disposed about a rotation axis fixed to the input shaft and a second magnetic or ferromagnetic ring is disposed about the rotation axis fixed to the output shaft. At least one is formed as an arrangement of permanent magnets. The first and second rings are disposed one within the other around the rotation axis. The magnetic coupling between the rings in combination with the effect of an output load results in the desired reciprocating motion of the output shaft.

Embodiments disclosed herein relate to a garment system including a flexible compression garment, at least one sensor, and at least one therapeutic stimulation delivery device operable responsive to sensing feedback from the at least one sensor, effective to provide therapeutic radiation to a body part of a subject. Embodiments disclosed herein also relate to methods of using such garment systems.

A CPR chest compression device with a cooling exhaust flow path configured to direct cooling air flow through the device. A CPR chest compression device with a battery retainer interoperable with the control system to provide for controlled shut-down when an operator attempts to remove the battery during operation.

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.

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.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) and after resuscitation includes a base and an upper support operably coupled to the base. The upper support is configured to incline at an angle relative to the base to elevate an individual's upper back, shoulders and head. The elevation device includes a support arm coupled with the upper support. The support arm is movable to various positions relative to the upper support and is lockable at a fixed angle relative to the upper support such that the upper support and the support arm are movable as a single unit relative to the base while the support arm maintains the angle relative to the upper support. The elevation device also includes a chest compression device coupled with the support arm. The chest compression device is configured to compress the chest.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

An example of a system for providing emergency care to a patient includes an automated chest compression device configured to engage the patient at the patient's sternum to provide multiple chest compression cycles to the patient's sternum, an automated mechanical ventilation device to induce negative pressure ventilation, and a controller operably coupled to the automated chest compression device and the automated mechanical ventilation device and including one or more processors configured to control the automated chest compression device to cyclically perform chest compressions, and control the automated mechanical ventilation device to cyclically induce the negative pressure ventilation out-of-phase with the chest compressions such that the automated mechanical ventilation device cyclically induces the negative pressure ventilation prior to each compression of the patient's sternum.

A system and method for determining CPR induced chest compression depth using two sensors while accounting for different orientations of the two sensors.
