摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A novel apparatus and method for recording and replaying patient treatment and response data that occurs during the course of an emergency response on a defibrillator. The data and events of an emergency response may be recorded automatically by the defibrillator. Incidents may then be randomly accessible (i.e. “scrollable”) by medical personnel on the defibrillator by placing the defibrillator into an incident review mode. The ability to quickly review critical ECG and event data on the scene. This provides medical personnel with a reliable and efficient alternative to paper based recording systems.
摘要:
A defibrillator system capable of defibrillation and patient monitoring. When used as a patient monitor, the defibrillator system includes a defibrillator and removable monitoring electrodes. The monitoring electrodes communicate with a monitoring adapter and the defibrillator. A method of detecting the presence of the monitoring electrodes by the defibrillator is also included. A removable monitoring adapter. The removable monitoring adapter having a test impedance. Defibrillators include semi-automatic defibrillators and automatic defibrillators (“AEDs”).
摘要:
A reliable battery module that is safe is of critical importance to battery operated medical devices. This invention limits the amount of active materials in each cell of a battery module. Limiting the amount of active materials in each cell increases the safety and reliability of the battery module by minimizing the effect of a damaged or defective cell on the battery module output and on the potential hazard that such a cell can cause.
摘要:
An automatic external defibrillator is described that includes a high voltage delivery circuit for producing an electrical pulse to defibrillate a patient. In a preferred embodiment the electrical pulse is a biphasic or multiphasic electrical pulse. In one embodiment, the delivery circuit includes a high voltage capacitor coupled with a bridge circuit. The capacitor stores electrical energy for delivery to the patient, and the bridge circuit has four switching elements that are selectively switched to steer the current through the patient. A disarm circuit shunts the bridge circuit and operates to route energy away from the bridge circuit in the event a fault condition is detected, such as a short circuit at the patient electrodes. An example disarm circuit is a series-connected SCR and resistor. Also, a limiting circuit element (such as a resistor or an inductor) is provided in series with the capacitor. Together with the disarm circuit, the limiting circuit element reduces the voltage experienced by the bridge circuit switching elements when switched off in response to the detected fault condition. Consequently simpler, more robust, and less expensive high voltage delivery circuits are provided, as compared to conventional defibrillator circuit designs. A snubber circuit is also provided to prevent voltage from reaching the patient when the device is in standby mode.
摘要:
A data card drawer for installing a data card, such as a compact flash card, into a device that uses data cards. Devices that use data cards include, for example, medical devices, and more particularly defibrillators. The data card drawer electrically isolates the data card from the user when the user is installing or removing the data card from the device. The data card drawer may also be formed to provide a closure to the opening in the device housing provided to receive the data card. Further, the data card drawer may be formed to prevent damaging pins located on a pin connector within the receiving device which communicate data with the data card. The data card drawer preferably mates with the device to prevent ingress and egress of foreign matter and moisture.
摘要:
A control system for an electrotherapy device is provided. In particular, controlling the operation characteristics and functionality of an external electrotherapy device using a removable battery pack. Electrotherapy devices include defibrillator, cardioverters and training devices that simulate the operation of an electrotherapy device. Defibrillators include automatic or semi-automatic external defibrillators (AEDs). The operation characteristics include, training, administrative, automated use, manual use, and manufacturing use operation modes.
