摘要:
A defibrillator electrode and enclosure are described in which the 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.
摘要:
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.

摘要:
The present invention provides a self-storing medical electrode (10) 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 (15) comprising a heat-sealable material and the second side comprises a conductive layer (16). The electrode further comprises an electrically conductive gel layer (18) disposed on the electrode body and which is further in electrical communication with the conductive layer (16).
摘要:
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.
摘要:
A method and article for storing an automatic external defibrillator for use without a prescription are described. The hermetically sealed electrode pads of the OTC AED are electrically coupled to the OTC AED base unit where they are constantly accessible to self-test circuitry inside the base unit for periodic, automatic self-test. In one embodiment the self-test is designed to determine whether the conductive gel of the electrode pads has dried out. In another embodiment self-test circuitry also tests the battery while the OTC AED is being stored prior to use.
摘要:
A defibrillator having a pair of electrodes for delivering a defibrillation shock and a method thereof is provided. The defibrillator includes an energy-source circuit that may be discharged through electrodes on a patient to provide a biphasic voltage or current pulse. The energy-source-storage circuit is coupled across a bridge switch for delivering a defibrillation pulse to the patient through a pair of electrodes. A controller operates to control the entire defibrillation process and detects shockable rhythms from the patient via an ECG front end. The controller determines the source of the defibrillator to match the selected mode, which is inputted by connecting coded accessories, such as internal paddles, adult electrodes, or pediatric external electrodes to deliver appropriate defibrillation shocks. Other types of patient-dependent parameters are also employed to achieve the impedance compensation.

An electronic device includes a housing (20) having a first interior region (26) and a second interior region (28). The second interior region (28) is sized to receive an electronic interface (18). The device also includes a wound capacitor core (14) adapted for electrical communication with the second interior region (28), and a capacitor potting material (38) disposed in contact with the first interior region (26) and the wound capacitor core (14).
摘要:
A method and article for packaging an automatic external defibrillator for use without a prescription are described. The OTC AED is encased in a rigid polymeric disclosure which is a distinctive color or set of colors to enable the OTC AED to be readily distinguished in the home environment. The defibrillator is packaged in a box with multicolored depictions of the defibrillator on multiple sides of the box, which enable the distinctive coloring of the defibrillator to be readily identified by the exterior of the packaging.
摘要:
In accordance with the present invention, an electrotherapy device (12) includes a controller (44), an energy source (42), at least one electrode (46) for providing electrotherapy to a patient (48), an energy delivery system (49) operable by the controller to deliver an electrical shock from the energy source (42) to the electrode (46), and a removable battery pack (10) that serves as the energy source (42). The removable battery pack (10) includes a housing having a user accessible interior and an exterior configured to be removably insertable into a battery receptacle (20) of the electrotherapy device (12). The battery pack (10) also includes at least one user replaceable, non-rechargable cell (18) located in the interior of the housing. The cell (18) has a positive and negative terminal. A pair of conductive contacts is located in the interior of the housing. One of the conductive contacts is coupled to the positive terminal of the cell (18) and the other conductive contact is coupled to the negative terminal of the cell (18). A battery pack circuit (8) located in the interior of the housing is in electrically operative communication with the cell (18).
