A system and method for mechanical CPR can include a device for providing compressive force to various locations on a patient, and biological monitoring systems to measure the effectiveness of the various locations of compressive force in pumping blood through the patient. The system can also include providing decompressive force to increase the efficacy of blood flow.

Arrangement for compression sensing between two objects, preferably for compression treatment, in particular compression therapy arrangement, comprising a first object, e. f. a compression garment adapted to exert external pressure on a second object, e. g. a body portion and at least one sensor device associated with the first object and having at least one pressure sensor for determining the external pressure, wherein the pressure sensor comprises at least one pressure circuitry, having a sensing impedance which is dependent on the external pressure and at least one reference circuitry having a reference impedance which is essentially independent from the external pressure, wherein a cumulative signal which is dependent on the external pressure and other external influences acting in the vicinity of the sensing impedance is derivable from the pressure circuitry and a reference signal which is essentially independent from the external pressures but dependent on other external influences acting in the vicinity of the reference circuitry.

A device for compressing the chest of a cardiac arrest victim.

Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.

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.

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

Devices and methods for performing CPR on a patient within an imaging field of an imaging device. The device has a compression belt and a belt tensioning mechanism, both located on or in the device such that the head, neck, thorax and abdomen of the patient may be place within the imaging field with the compression belt installed about the patient and the belt tensioning mechanism will be located outside of the imaging field.

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 chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.
