The present invention relates to a stimulation electrode comprising an ionically conductive pressure sensitive adhesive composition comprising a) a (meth)acrylate resin comprising at least 10% of a (meth)acrylate monomer comprising OH-group by weight of the total weight of the (meth)acrylate resin; and b) an ionic liquid. The stimulation electrode according to the present invention is used in skin applications transferring an electrical signal to the body via skin.

An electrode plate and a wearable defibrillation device are disclosed. The electrode plate includes a hermetic shell and a capsule disposed in the hermetic shell. The hermetic shell has an inflation port and an overflow aperture. The overflow aperture is provided in an exposed surface of the hermetic shell, which has electrical conductivity. The capsule includes a body and a cover. The body defines a hollow cavity and an outlet orifice in communication with the cavity. The cavity is configured for storage of a conductive paste therein and is isolated from a hollow internal space of the hermetic shell. The cover is disposed over the outlet orifice so as to close the outlet orifice. When the cover is broken open, an opening therein resulting from the breakage comes into communication with the outlet orifice and the overflow aperture, allowing the conductive paste in the cavity to flow successively through the outlet orifice, the opening in the cover and the overflow aperture onto the exposed surface. Such automatic application of the conductive paste can provide timely protection to a patient and enhance safety in release of the conductive paste.

A wearable medical device is provided. The wearable medical device includes a garment that includes a sensing electrode, at least one of an inductive element and a capacitive element included in at least part of the garment, and a controller. The controller may be configured to determine a confidence level of information received from the sensing electrode based on at least one of an inductance of the inductive element and a capacitance of the capacitive element.

A peelable lid system includes a peelable lid, a seal configured to seal the peelable lid to a container, a handle coupled to the peelable lid, and a lifting mechanism coupled to handle. The lifting mechanism can be coupled to the peelable lid at a plurality of attachment points, including at least one attachment point coupled to the peelable lid away from the handle. The lifting mechanism can be configured to lift at least one portion of the peelable lid near each of the plurality of attachment points.

Technologies and implementations for a defibrillator electrode having communicative capabilities are generally disclosed.

An electrode assembly that includes an electrically conductive layer, a first impedance reduction system, and a second impedance reduction system. The electrically conductive layer forms an electrode portion of the electrode assembly and a first surface to be placed adjacent a person's skin. The first impedance reduction system is configured to dispense a first amount of an electrically conductive gel onto the first surface of the electrically conductive layer in response to a first activation signal. The second impedance reduction system is configured to dispense a second amount of the electrically conductive gel onto the first surface of the electrically conductive layer in response to a second activation signal.

Technologies and implementations related to utilizing conductive ink with medical device systems to facilitate electrical contact between an electrode and a person’s skin. The conductive ink may be applied in a variety of manners such as, but not limited to, permanent, semi-permanent, and/or temporary.

An improved user interface for a defibrillator (100) capable of being used with paddle electrodes (180) and adhesive pad electrodes (190). A shock delivery button (110) located on the defibrillator control panel delivers a shock through the pad electrodes. A second shock delivery button (210), located on the paddle electrodes, delivers a shock through the paddle electrodes. Both shock delivery buttons are configured with the same shape, operation and illumination in order to reduce user confusion.

This document relates to systems and techniques for the treatment of a cardiac arrest victim via electromagnetic stimulation of physiologic tissue.

An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions, at least one sensor connected to the pad, the sensor being configured to sense movement of the chest or force applied to the chest, processing circuitry for processing the output of the sensor to determine whether the rescuer is substantially releasing the chest following chest compressions, and at least one prompting element connected to the processing circuitry for providing the rescuer with information as to whether the chest is being substantially released following chest compressions.
