    摘要: A method of delivering electrical therapy to a patient by a medical device includes activating the medical device and performing a first analysis of a first set of data signals sensed by the medical device. If the first analysis shows the first set of data signals meets a first criterion, then charging of an energy delivery circuit is commenced upon completion of the first analysis. A second analysis of a second set of data signals from the patient is performed, and if the second analysis determines that the second set of data signals meet a second criterion, the therapy is delivered. The steps of performing the first analysis and performing the second analysis may be begun at substantially the same time. The step of charging may overlap in time with the step of performing a second analysis. The medical device may be an external defibrillator and the therapy may be a defibrillating shock.

    摘要: An upgrade kit and method for converting a typical monophasic defibrillator into a biphasic defibrillator is provided. The upgrade kit is easily connected to a typical monophasic defibrillator and uses control signals that are commonly available in most monophasic defibrillators. Such control signals include the signals for transferring the defibrillation pulse to the patient, and for dumping unwanted energy from the energy storage capacitor. In addition, the upgrade kit avoids the need for information as to the charge level of the storage capacitor by using a discharge method that allows the production of proper biphasic defibrillation pulses regardless of the initial energy settings of the storage capacitor. More specifically, the upgrade kit determines the desired length of the biphasic defibrillation pulses according to two measurements which are taken during the defibrillation pulse. These two measurements are converted to an index referenced in a look-up table to determine the desired lengths of the two phases of the biphasic defibrillation pulse.

    摘要: An external defibrillator with an output circuit having four legs arrayed in the form of an “H” (an “H-bridge”) is disclosed. The output circuit is designed to be able to conduct a range of defibrillation pulse energies, from below 50 joules to above 200 joules. Each leg of the output circuit contains a solid-state switch. By selectively switching on pairs of switches in the H-bridge, a biphasic defibrillation pulse may be applied to a patient. The switches in three of the legs of the H-bridge output circuit are preferably silicon controlled rectifiers (SCRs). Gate drive circuits are coupled to the SCRs to bias the SCRs with a voltage that allows the SCRs to remain turned-on even when conducting low current. The switch in the fourth leg is preferably a pair of insulated gate bipolar transistors (IGBTs) coupled in series. A gate drive circuit is coupled to the gate of the IGBTs to provide a slow turn-on and a fast turn-off of the IGBTs. The gate drive circuit also biases the IGBTs with a sufficient voltage to allow the IGBTs to withstand a shorted discharge of the external defibrillator through the output circuit. The circuit also includes a protective component that has both inductive and resistive properties. An internal energy dump may be performed by biasing on two legs on the same side of the H-bridge output circuit, thus eliminating the need for a separate energy dump circuit.

    摘要: An external defibrillator (8) with an output circuit (14) having four legs arrayed in the form of an "H" (an "H-bridge") is disclosed. Each leg of the output circuit contains a solid-state switch (31, 32, 33, 34). By selectively switching on pairs of switches in the H-bridge, a biphasic defibrillation pulse may be applied to a patient. The switches in three of the legs of the H-bridge output circuit are preferably silicon controlled rectifiers (SCRs). Gate drive circuits (51, 53, 54) are coupled to the SCRs to bias the SCRs with a voltage that allows the SCRs to remain turned-on even when conducting low current. The switch in the fourth leg is preferably a pair of insulated gate bipolar transistors (IGBTs) coupled in series. A gate drive circuit (52) is coupled to the gate of the IGBTs to provide a slow turn-on and a fast turn-off of the IGBTs. The gate drive circuit (52) also biases the IGBTs with a sufficient voltage to allow the IGBTs to withstand a shorted discharge of the external defibrillator through the output circuit. The circuit also includes a protective component (27) that has both inductive and resistive properties. The protective component (27) serves to both limit current during a defibrillation pulse, and to absorb energy during an internal energy dump. An internal energy dump is performed by biasing on the switches in two legs on the same side of the H-bridge output circuit (14), eliminating the need for a separate energy dump circuit.
