An improved self-testing method is described which is incorporated into a defibrillator. The method performs a self-testing protocol which operates on a first frequency until a threshold condition is reached. When the threshold condition is reached, the self-testing protocol switches to a second frequency. Such a method enables quicker identification of a failure mode in a population of defibrillators, while maintaining acceptable battery life in the device.

Adaptive self-testing and stress analysis of medical devices

An improved self-testing method is described which is incorporated into a defibrillator (). The method performs a self-testing protocol which operates on a first frequency until a threshold condition is reached. When the threshold condition is reached, the self-testing protocol switches to a second frequency. Such a method enables quicker identification of a failure mode in a population of defibrillators, while maintaining acceptable battery life in the device.

A heart monitoring method is disclosed including an electroacoustic transducer such as an earphone coupled to a controller. The method proceeds with positioning a transducer in a person's ear in acoustic communication with the tympanum. Signals from the transducer are processed to determine the presence of pulsatile blood flow. The heart monitor may be incorporated into a portable media playback device alternating between playback and monitoring mode or performing both simultaneously using one earphone for each function. The heart monitor may be incorporated into a defibrillator to sense the presence of blood flow for use in a shock delivery decision.

Aural heart monitoring apparatus and method

A system and method are described for delivering electrotherapy to a patient that includes delivering electrotherapy to defibrillate the patient and providing at least one non-interruptible time period for administration of CPR prior to entering a monitor mode during which a patient cardiac signal is monitored for indication of a shockable rhythm.

AED having mandatory pause for administrating CPR

An AED unit is operable to selectively switch to a pediatric rescue protocol by inserting a key-like device into an aperture of the AED unit. A sensor inside the case of the AED unit senses the presence of the device in the slot and responds by executing the pediatric rescue protocol. A separate electrode pad mating connector on the AED unit receives an electrode pad connector, the associated electrode pads being suitable for either adult or pediatric patients.

Automatic external defibrillator for adult and pediatric patients

A current limiter for a defibrillation pulse is powered by the defibrillation pulse and switches the current delivery path open and closed when an excessive current condition exists. The excessive current condition is sensed by a sense resistor of the current limiter. The controlled current is delivered by an inductor which delivers a current which varies in a range about a predetermined current level during excessive current conditions. The current limiter dissipates little energy of the defibrillation pulse so that most of the energy produced by the defibrillator is delivered to the patient.

Energy efficient defibrillation current limiter

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 ().

A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case is constructed without protrusions and with a rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case is further constructed with a bracket or optional test fixture for a CPR Meter.

Systems and methods for transferring medical information from a first medical monitoring device to a second device are provided. Medical information from the first medical monitoring device is encoded as an ECG waveform and the ECG waveform having the encoded medical information is provided to the second device as an input ECG waveform.

A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case is constructed without protrusions and with a rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case latch is further constructed for greater ease of case opening and closing, and for greater latch hold strength.

An AED unit which is operable to selectively execute either an adult rescue protocol or a pediatric rescue protocol is causes to execute the pediatric rescue protocol by inserting a key-like device into a slot of the AED unit. A sensor inside the case of the AED unit senses the presence of the device in the slot and responds by executing the pediatric rescue protocol. In an illustrated embodiment the AED unit includes a lighting mechanism which is used to light an illustration showing the proper placement of electrode pads on an adult patient. The key-like device includes an illustration showing the proper placement of electrode pads on a pediatric patient which obscures the adult illustration when the device is inserted in the AED unit. The key-like device is configured to make use of the same AED unit lighting mechanism to light the pediatric pad placement illustration.

A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case is constructed without protrusions and with an arcuate and semi-rigid or rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case is further constructed with a wide angle viewing ready status light pipe for greater ease of maintenance of the contents.

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.

The carrying case is constructed without protrusions and with a rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case integrates a actuator to periodically test the operation of the defibrillator push buttons.
