An automated external defibrillator (AED)has a changeable language placard () which enables the AED to instruct the user in one or more languages. The placard includes a controlling element () which is sensed by the AED, and causes the AED to automatically switch the language mode into the corresponding placard language. The placard also includes visual guidance instructions ().

Language placard for an automated external defibrillator

Defibrillator electrodes are sealed to the inside of a rigid enclosure. The enclosure is hinged to open and expose the electrodes for deployment. The electrode gel is sealed against moisture loss between the moisture impervious electrode backing and the inner surface of the enclosure. The enclosure may further include an electrical circuit for electrode self-testing, the circuit being broken when the enclosure is opened.

Electrode and enclosure for cardiac monitoring and treatment

A release liner for electrode pads is described which enables the pads to be used with defibrillators requiring the electrodes to be electrically interconnected for self-test prior to use, and with defibrillators which do not require the electrodes to be electrically interconnected. In one example this variation is afforded by folding the release liner one way to electrically connect conductive layers underlying two attached electrodes. In another example this variation is afforded by leaving the conductive layers electrically connected or breaking the connection.

Halibut release liner for a defibrillator electrode pad

A defibrillator electrode assembly with a slot-like storage case is described which protects the pads prior to use and retains them in either an electrically connected or electrically disconnected configuration. When the electrode assembly is slidably inserted into the case, an optional pinch clip within the case presses electrodes on opposite sides of a thick release liner into electrical contact with each other.

Pinch case for defibrillator electrode pads and release liner

A case for defibrillator electrode pads on a release liner is described which protects the pads prior to use and retains them in either an electrically connected or electrically disconnected configuration. When the case is closed, spring contacts on opposite sides of the inside of the case retain the pads and release liner in place. The retention either holds electrical conductors in contact with each other to retain the pads in electrical connection with each other, or in a different configuration in which the pads are not electrically connected.

Case for defibrillator electrode pads and release liner

An electrode includes a conductive adhesive layer and a conductive foil layer having a void therein. One such electrode may be mounted in conjunction with another electrode upon a release liner having one or more openings therein to facilitate electrical signal exchange between electrodes. A release liner may include a moisture permeable and/or moisture absorbent membrane. A release liner may alternatively include a conductive backing layer. A release liner may also include an insulating swatch covering an opening. A release liner may be implemented as a foldable sheet, such that multiple electrodes may be mounted upon the same side of the foldable sheet. A medical device to which the mounted electrodes are coupled may characterize the electrical path between the electrodes. The medical device may perform a variety of electrical measurements, including real and/or complex impedance measurements. Based upon one or more measurements, the medical device may provide an indication of electrode condition, fitness for use, and/or an estimated remaining lifetime. An electrode condition indicator, which may form a portion of the medical device, may generate, present, or display electrode condition and/or estimated remaining lifetime information via a visual metaphor, such as a fuel gauge.

Medical electrode and release liner configurations facilitating packaged electrode characterization

The present invention provides a self-storing medical electrode () that does not require packaging, enclosures, or other means to house and to protect various electrode components. According to one aspect, the invention provides an electrode comprising an electrode body having first and second sides, wherein the first side comprises a barrier layer () comprising a heat-sealable material and the second side comprises a conductive layer (). The electrode further comprises an electrically conductive gel layer () disposed on the electrode body and which is further in electrical communication with the conductive layer ().

Self-storing medical electrodes

An automatic external defibrillator electrode package includes a coded conductive label that uniquely identifies the type of automatic electrode contained therein. Pins on the defibrillator body make electrical contact with the conductive label when the package is attached to the defibrillator. These pins sense the shape of the conductive label to ascertain the electrode type, thereby enabling the AED to automatically set the proper operating mode.

Identification system for defibrillator electrode package

Handling or removal of a pair of pre-connected defibrillator electrode pads from their package, or a compartment in the defibrillator, is detected in order to effectively time the issuance of prompts to guide the user. Detection occurs when an impedance level between the electrode pads varies sufficiently over time to indicate occurrence of the handling or removal event. The pads are preferably configured to leverage variability in the impedance that results from bending of pads during handling or removal.

Method of detecting when electrode pads have been handled or removed from their package

Defibrillator electrode cartridge

A medical connector and adapter system that includes: a male cable connector, and a female cable-receiving housing for electrically coupling with the male cable connector. The male cable connector has a protrusion that is adapted to slide over the wall of the female cable-receiving housing. In one embodiment, the protrusion prevents the male cable connector from mating with a female cable-receiving housing that is incorporated into the housing of a defibrillator when there is no accommodation in the defibrillator housing to receive the protrusion. Further the male cable connector is electrically connected to pediatric electrodes and enables pediatric electrodes to be used with a manual defibrillator.

Medical connector system and method of use

A medical connector and adapter system that includes: a male cable connector, and a female cable-receiving housing for electrically coupling with the male cable connector. The male cable connector has a keying protrusion that corresponds to a keying channel in the cable-receiving housing. The keying feature prevents the male cable connector from being installed into a cable-receiving housing that does not have a keying channel.
