A method and apparatus for identifying electrodes attached to a defibrillator and adjusting patient therapy delivered by a defibrillator in response thereto.

Smart medical connector system and method of use

A cartridge is provided for storing one or more electrode pads such as a defibrillator electrode pad. The cartridge includes a housing having a rigid portion, a storage space disposed within the housing, and a storage-space opening that allows one to remove/insert the electrode pad or pads from/into the storage space. Because it has a housing with a rigid portion, such a cartridge can better protect one or more electrode pads from handling damage. Furthermore, one can construct the cartridge such that it is attachable to a medical device such as an AED. This allows an operator to carry or store the medical device, cartridge, and one or more electrode pads as a single unit. In addition, one can construct the cartridge such that the one or more electrode pads can be pre-connected to the medical device. This can eliminate connecting the one or more electrode pads to the medical device during an emergency.

Cartridge for storing an electrode pad

An apparatus for delivering defibrillation therapy to a patient. Specifically, an external defibrillators or automatic or semi-automatic external defibrillator (AEDs) is described. The defibrillator is automatically activated or inactivated by, for example, inserting or removing an object, such as a plug or a pin, into a receptacle within the defibrillator housing.

Object activated defibrillator

A method of using a measuring instrument of unknown calibration in such a way as to correct the calibration. The method includes taking a measurement with the instrument, storing the measurement in a data storage medium, and correcting the measurement at a later time based on a determination of the amount of error in the measuring instrument. The method may also be used to remove error that is present as a result of inaccuracies that are present in the data gathering instrument. This method can be used in a write variety of instruments that are used to take measurements, but is particularly useful for medical instruments.

Method of using a measuring instrument and data gathering system

A method of using a measuring instrument of unknown calibration, the method including taking a measurement with the instrument; storing the measurement in a data storage medium; and correcting the measurement at a later time based on a determination of the amount of error in the measuring instrument. In a specific embodiment, this invention also relates to methods of gathering event data and removing error that may have been present as a result of inaccuracies in the event gathering instrument.

A method of indicating operational status of an electronic device, the device providing an indication of device operational status as a result of a self-test, the method including the following steps: monitoring an environmental condition; changing an indication of device operational status from a first indication to a second indication if the monitored environmental condition changes from a first condition to a second condition, this changing step being performed without performing a self-test. In certain embodiments, the monitored environmental condition is a monitored temperature, the first condition is a first temperature and the second condition is a second temperature. The electronic device may be battery-operated, in which case the self-test is a battery capacity test. In these embodiments, the method also may include the step of performing the battery capacity test when the monitored temperature reaches the second temperature if there is no indication of device operational status corresponding to the second temperature stored in memory, the second temperature is lower than a temperature associated with an indication of a non-warning device operational status stored in memory, and the second temperature is higher than a temperature associated with an indication of a warning operational status; and indicating device operational status as a result of the battery capacity test. The method may also include the step of storing in memory an association between the second temperature and device operational status.

Environment-responsive method for maintaining an electronic device

A method of indicating operational status of an electronic device, the device providing an indication of device operational status as a result of a self-test, the method including the following steps: monitoring an environmental condition; changing an indication of device operational status from a first indication to a second indication if the monitored environmental condition changes from a first condition to a second condition, this changing step being performed without performing a self-test. In certain embodiments, the monitored environmental condition is a monitored temperature, the first condition is a first temperature and the second condition is a second temperature. The electronic device may be battery-operated, in which case the self-test is a battery capacity test. In these embodiments, the method also may include the step of performing the battery capacity test when the monitored temperature reaches the second temperature if there is no indication of device operational status corresponding to the second temperature stored in memory, the second temperature is lower than a temperature associated with an indication of a non-waning device operational status stored in memory, and the second temperature is higher than a temperature associated with an indication of a warning operational status; and indicating device operational status as a result of the battery capacity test. The method may also include the step of storing in memory an association between the second temperature and device operational status.

Environment-response method for maintaining an external medical device

A method of maintaining an electronic device, the method including the steps of monitoring ambient an environmental condition such as temperature or humidity; monitoring a self-test initialization criterion; performing an automatic device self-test if the self-test criterion is met and if the environmental condition is within a predetermined range; and not performing the automatic device self-test if the self-test criterion is met but the environmental condition is outside the predetermined range. In a preferred embodiment, the device is an external defibrillator.
