Embodiments described herein relate to a garment system including at least one muscle or at least one joint activity sensor, and at least one actuator that operates responsive to sensing feedback from the at least one muscle or the at least one joint activity sensor to cause a flexible compression garment to selectively compress against or selectively relieve compression against at least one body part of a subject. Embodiments disclosed herein also relate to methods of using such garment systems.

In some embodiments, a method may include monitoring use of a medical device. The method may include positioning a wearable harness of a medical device on a subject. The method may include selectively positioning at least some of a plurality of engines on and/or adjacent at least one treatment area. The method may include applying an oscillation force to at least one of the treatment areas using at least some of the engines. The method may include mobilizing at least some secretions in an airway within the subject substantially adjacent the treatment areas. The method may include monitoring use of the medical device by the subject using a controller associated with the medical device to determine if the medical device has been used effectively as prescribed.

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 mechanical chest compression device is secured to a gurney, transport stretcher or ambulance cot while engaging a patient's thorax to provide mechanical CPR during transport. The mechanical chest compression device compresses the patient's thorax against the gurney deck. The mechanical chest compression device may engage the side rails on the gurney, the gurney deck or any suitable structural elements of the gurney.

A massaging garment is provided that may be useful for the treatment of lymphedema or other conditions where massaging a limb is desired. In one embodiment, the massaging garment comprises a sheet of flexible material and a plurality of electrically actuable fibers that are incorporated with the sheet of flexible material. The electrically actuable fibers are spaced apart from each other, and each electrically actuable fiber is actuable to contract when actuated with electricity. The garment also comprises a control module connected to each of the electrically actuable fibers to selectively provide electricity to each electrically actuable fiber to cause each fiber, when selected, to contract. A method of massaging a limb with a garment, and a method of producing a garment are also provided. A method of producing an electrically actuable material is also provided.

An apparatus 40 for enhancing venous blood flow through a limb of a subject includes a detachable compression sleeve 41 extendable around the subject's limb and having a plurality of compressors 43-48 situated next to one another along the sleeve 41. In use, the compressors 43-48 substantially encircle the limb and compress the limb in a continuous cyclical compression sequence to move blood within the limb from the distal end of the sleeve 41 to the proximal end to replicate venous blood flow and to prevent backflow. In particular, as a said first compressor begins to compress the limb, a said second compressor preceding the first compressor in sequence already compresses the limb and continues to compress the limb at least until the first compressor compresses the limb to substantially the same extent as the second compressor, and a said third compressor which precedes the second compressor in sequence ceases to compress the limb.

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.

Disclosed is a system and method for regulating tourniquet cuff pressure to restrict blood flow penetration past the cuff based on a personalized restrictive pressure (PRP). The system includes mechanisms for estimating a limb occlusion pressure (LOP) by determining a minimum pressure at which arterial blood penetration past an applied tourniquet cuff is stopped and measuring a pulsation characteristic associated with the LOP. Thereafter, the system establishes a PRP by determining a second pressure that restricts but does not stop arterial blood penetration past the cuff and that corresponds to a second pulsation characteristic differing by a percentage from the pulsation characteristic associated with the LOP. During a limb-activity time period, the system maintains pressure in the applied tourniquet cuff near the PRP, thereby restricting but not stopping arterial blood penetration past the cuff during the activity time period.

A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is varied based on feedback gathered from physiological sensors that detect physiological characteristics of the patient during treatment.
