Energy delivery apparatus and method

摘要

There is provided an energy delivery device comprising a storage device, a discharge circuit and a disarm circuit. The discharge circuit comprises a switch electrically connected to the storage device, and is selectively operable to deliver energy from the storage device to a load, e.g., a patient needing defibrillation, preferably in a multiphasic waveform. The disarm circuit comprises the switch. Preferably, the discharge circuit comprises an H-bridge circuit. There are also provided delivery devices: which comprise a shoot-through elimination circuit; which include housing elements which, when assembled, cause electrical connection between respective components; which include a housing having a small volume and an energy storage device having a large capacitance; which comprise a shunt circuit which, when activated, prevents switching of a switch. There are also provided methods of assembly and disassembly of an energy delivery unit and methods of delivering energy to a load.

主权项

1. A device comprising:
an energy storage device; an energy discharge circuit operably coupled to the energy storage device, the energy discharge circuit being operable to deliver energy from the energy storage device to a patient by at least one switch included in the energy discharge circuit, the at least one switch being controlled by a controller, wherein the discharge circuit form an H-bridge circuit comprising four delivery switches which are operable to deliver at least one energy pulse, the at least one switch being one of said four delivery switches; and a disarm circuit also including the at least one switch, the disarm circuit being operable to prevent energy from being delivered to the patient when the disarm circuit is activated.
