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.

Embodiments relate to devices, systems and methods of assisting blood flow return to the heart from a limb. The device comprising a wearable garment and a compression apparatus embedded in the garment for applying an external compression to a limb of a user and at least one of a processor or a controller configured to control the compression apparatus to apply the external compression, according to a compression sequence, to a muscle of the limb of the user based on real-time measurements regarding a cardiac cycle having a diastolic phase and systolic phase of the user and real-time measurements of muscle activity. The compression sequence is synchronized to commence when both a local blood flow at the limb is in the diastolic phase and the muscle is in a non-contracted state.

A system for increasing blood flow through a user's limb during a blood collection procedure includes an inflatable cuff that is worm around the user's limb. A pump and a deflation valve are in fluid communication with the inflatable cuff. A heating element and a temperature sensor are attached to the inflatable cuff. The system also includes a motion sensor. A controller is in communication with the pump, the deflation valve, the heating element and the temperature and motion sensors and detects a blood pressure or blood flow of the user, controls inflation and deflation of the inflatable cuff and controls energization of the heating element based on data from the motion sensor and the temperature sensor.

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 purposely sub-optimal for circulation at least some of the time, and especially when it is detected that the patient has regained consciousness. An advantage can be that the patient may thus faint again, and therefore perceive less of the unpleasant experience of the mechanical chest compressions that the CPR system continues to perform on them as it preserves them alive.

A first exoskeleton is in communication with a central server or a peripheral device. The first exoskeleton collects first data and transmits the first data to the central server or peripheral device. The central server or peripheral device generates second data using the first data and transmits the second data to the first exoskeleton or a second exoskeleton.

Garment systems 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. Methods of using such garment systems are also described.

The present invention relates to a three-dimensional negative pressure stimulator module capable of performing customized composite stimulation for the improvement of skin functions that applies three-dimensional negative pressure stimulation as well as composite stimulation such as electric current stimulation, light stimulation, and thermal stimulation, which is helpful in improving functions of the skin, to skin compositively, and further has a function of sensing a skin state, thereby performing customized composite stimulation. The three-dimensional composite stimulator module includes: a negative pressure cup; and at least one diaphragm provided along the transmission path of the negative pressure of the negative pressure cup, wherein at least any one of negative pressure stimulation, light stimulation, thermal stimulation, and electrical stimulation is transmitted compositively to the skin or subcutaneous tissues.

A respiration-assistance apparatus or method can include or use a lifting element such as to cyclically push, pull, or lift, toward a superior direction of the subject, at least one subject region during an inhalation portion of a respiration cycle of the subject. A cyclical member can couple the lifting element to a fixed reference. Abdominal or ribcage compression can be provided. A multi-action or other cam can be used, such as together with a reciprocating element. Examples can be configured for use with a wheelchair, a bed, a vacuum or suction affixation element, a wearable garment, etc.

A supporting module, a motion assistance apparatus including the supporting module, and a method of controlling the motion assistance apparatus are provided. The supporting module may include a supporting member configured to enclose at least a portion of a support object, and a sensor module configured to sense information regarding whether the support object is out of a neutral position with respect to the supporting member.
