Defibrillator patient connection system with automatic identification
First Claim
1. A defibrillator system comprising:
- a defibrillator base unit for providing electrical energy to shock a patient;
means for administering the electrical energy to the patient;
a cable assembly for connecting the administering means to the base unit;
a plug assembly coupled to one end of the cable assembly and arranged for interfitting engagement with the base unit;
a first discharge switch disposed in the plug assembly;
discharge means in the base unit for delivering the electrical energy to the cable assembly to shock the patient in response to actuation of the discharge switch while the plug assembly is connected to the base unit;
means for locking the plug assembly in interfitting engagement with the base unit while in use; and
means for preventing actuation of the discharge switch unless the plug assembly is locked in interfitting engagement with the base unit.

Abstract
A defibrillator patient connection system is disclosed for automatically identifying to a defibrillator system the type of pads or paddles assembly connected to the system for conveying electrical energy to shock a patient. Each of the available pads or paddles assemblies is identified by a corresponding analog voltage level provided to the base unit through a corresponding cable assembly. The identification voltage is sensed by an A/D converter in the defibrillator base unit. The identification voltage is provided to the base unit on a charge-done signal line which otherwise is asserted by the base unit to controllably actuate a charge-done indicator light in an external paddles assembly. The disclosed methods and apparatus thus maintain a simple defibrillator/cable assembly interface and require no additional signal lines for implementing automatic identification. A plug assembly latch mechanism also is disclosed that provides the dual functions of locking a plug assembly in place in the defibrillator base unit and preventing actuation of discharge buttons on the plug assembly when the latch is not in the locked position, thereby avoiding a high energy discharge unless the plug assembly is securely locked in position.
