A compact automated external defibrillator (AED) is a device configured to receive electrocardiogram signals while the AED's electrode pads are in airtight storage. A surface of the device has a first electrical connection and a second electrical connection to a circuit board, each at a separate defined location on the surface. The circuit board receives ECG signals from a patient when the first defined location and the second defined location on the surface of the device body are put in contact with the patient. The circuit board may be configured to sense ECG signals from the patient through a plurality of additional defined locations on the surface of the device.

The device of the present invention comprises an intervening release liner as a common special feature, and the intervening release liner covers a part of an adhesive surface of a patch. The intervening release liner gets away from the patch, and is fixed to a patch application support (or porator tab). Due to such constitution, under a situation in use where the first part of the adhesive area of the patch adheres to a skin surface, the patch application support is slidable along the skin surface while peeling the intervening release liner from said part of the adhesive area of the patch to adhere to the skin surface.

A transcutaneous neurostimulation therapy system can include an electrostimulation electronics unit, including first and second neurostimulation output which can be respectively coupled to first and second neurostimulation skin electrodes, and the electrostimulation electronics unit can include or be coupled to a rechargeable battery. The transcutaneous neurostimulation therapy system can also include battery charging circuitry configured for being coupled via the first and second neurostimulation output terminals to the electrostimulation electronics unit for charging the battery of the electrostimulation electronics unit through the first and second neurostimulation skin electrodes.

A body electrode unit includes a body electrode and a release sheet to which the body electrode is attached. The body electrode includes a first electrode configured to stimulate a muscle of a body, a second electrode, and a third electrode. The second electrode and the third electrode are configured to detect a physiological signal from the muscle that is stimulated by the first electrode. The body electrode also includes a first connection portion arranged between the first electrode and the second electrode, and a second connection portion arranged between the third electrode and one of the first electrode and the second electrode. The first connection portion has at least one first direction changing part configured to change a direction in which the first connection portion extends, such that at least one of a distance and an angle between the first electrode and the second electrode is adjustable.

This bioelectrode is configured by applying a water-absorbing resin to a sheet-like structure including conductive fibers so as to have a moisture retention index of 0.8 or more. This bioelectrode-equipped apparatus comprises a fabric structure having, on a base fabric formed from an elastic fabric, an electrode placement region that includes a wiring formed on a surface of the base fabric, a bioelectrode provided to the terminal end of the wiring, and an insulating layer for covering the wiring, wherein the base fabric has a first extension direction exhibiting relatively low extensibility in the electrode placement region and a second extension direction which is different from the first extension direction and which exhibits higher extensibility than the first extension direction, and the wiring is formed along the first extension direction.

In rehabilitation, a stimulation pattern when applied to a body part by a neuromuscular electrical stimulation (NMES) device is effective to cause the body part to perform an intended action. The applying includes increasing a stimulation level at which the stimulation pattern is applied over time and, during the applying, acquiring video of the body part. The body part is monitored during the applying by analysis of the video, and the applying is automatically stopped in response to the monitoring indicating the body part has performed the intended action. The stimulation pattern may be defined as one or more subsets of electrodes of the NMES device and an electrode group stimulation level for each respective subset of electrodes, and the increasing of the stimulation level comprises increasing a scaling factor applied to the electrode group stimulation levels over time.

Alternating electric fields (e.g., TTFields) may be applied to a subject's body using an electrode assembly that includes a skin contact layer formed at least partially of a conductive adhesive composite. An electrode element is electrically coupled to the conductive adhesive composite. Optionally, the electrode assembly can include a layer (e.g., sheet) of anisotropic material between the electrode element and the skin contact layer. Optionally, the skin contact layer may comprise an outer adhesive layer comprising conductive adhesive composite, an inner adhesive layer comprising conductive adhesive composite, and a substrate positioned between the inner and outer adhesive layers.

A method of reducing stimulation signal interference with an electrical monitoring device includes sensing an electrical interference signal at a first location in a body resulting from delivery of an electrical muscle stimulation signal at a second location in the body, and delivering an electrical counter signal to the patient that destructively interferes with the electrical interference signal to prevent interference with the electrical monitoring device.

In a treatment arrangement for treating a surface, with a planar electrode array (2,2′), to which an electrical voltage can be fed, and with a planar shielding layer (1) which is made of an insulating plastic and which ate least partially surrounds the electrode array (2,2′), a reliable and fixed connection between the electrode array (2,2′) and shielding layer (1) is achieved by the fact that electrode array (2,2′) is made of a pourable plastic provided with plastic additives and that, in the region of a boundary layer (22) between electrode array (2,2′) and shielding layer (1), the plastics of the electrode array (2,2′) and of the shielding layer (1) are connected to each other by material bonding.

Systems and methods for a smart bandage for monitoring and treating wounds are provided herein. The smart bandage may be a smart, wearable, flexible multi-layer substrate that may include a system that can monitor wound characteristics, perform autonomous bioanalysis of wound characteristics to determine wound treatment plans in a non-invasive method, perform drug delivery or antimicrobial agent release to treat and prevent infections, and promote healing by electrical stimulation. The smart bandage may be equipped with a wireless network that can communicate with users, such as patients and medical providers, directly about a patient's wound condition and provide for on-demand wound treatment.
