Abstract

Defibrillating device equipped with a plurality of connector/electrodes assemblies of different types. Defibrillating device equipped with a plurality of connector/electrodes assemblies of different types, having each at least a connector cable and adapted to be plugged in, in a removable and interchangeable manner, to the casing of the device at a single connection site equipped with a fixed complimentary connector, all of the control (13, 13'"'"') and, preferably, adjustment devices (17) of the functioning of the defibrillating device (1) being mounted on the connector (8)/electrodes (9, 9'"'"') assemblies, each type of which is intended for a class of authorized user and/or specific application(s), the casing (2) of the defibrillating device (1) having only indicator and/or display devices (2'"'"'), and preferably, no control or adjustment device.

Claims

1. Defibrillating system comprising a defibrillating device and a plurality of connector/electrodes assemblies of different types, each of which comprising at least one connecting cable adapted to be removably and interchangeably connected to a casing of said defibrillating device at a unique connection site equipped with a fixed mating connector, wherein all control (13, 13'"'"', 18, 21) and functioning adjustment devices (17) of said defibrillating device (1) are mounted on the connector (8)/electrodes (9, 9'"'"') assemblies, the casing (2) of said defibrillating device (1) comprising only display devices, and no control or functioning adjustment devices,

wherein a first type of said plurality of connector/electrode assemblies comprises a first control assembly with a display indicating discharge authorization, a manually operated variable energy selector, and two control buttons for controlling the defibrillating discharge at the manually selected energy level,

wherein a second type of said plurality of connector/electrode assemblies comprises a second control assembly without a manually operated variable energy selector and including a display indicating discharge authorization, a switch for requesting automatic determination by said defibrillating device of an energy level, and two control buttons for controlling the defibrillating discharge at the automatically selected energy level, and

wherein each of said first and second connector/electrode assemblies further comprise electrodes selected from the group consisting of paddle electrodes, internal electrodes and adhesive electrodes.

2. Defibrillating system according to claim 1, further comprising as many different functioning modes as there are different types of connector (8)/electrodes (9, 9'"'"') assemblies, a particular mode of functioning being selected automatically upon connecting a connector (8) of the plurality of connector (8)/electrodes (9, 9'"'"') assemblies to said fixed mating connector (7) of the casing (2) of the defibrillating device 1.

3. Defibrillating system according to claim 2, wherein each connector (8) of said plurality of connector (8)/electrodes (9, 9'"'"') assemblies comprises means for identifying itself to the casing (2) of the defibrillating device (1) upon its connection thereto, said identification means being specific to the type of connector (8)/electrodes (9, 9'"'"') assembly to which said connector (8) belongs, said identification means consisting of a state of at least one connection point (11) of said connector (8), when connecting said connector (8) in the casing (2) of the defibrillating device 1.

4. Defibrillating system according to claim 3, wherein said identification means generates a binary code by setting the states of said connection points (11) of the connector (8), each binary code thus obtained identifying, in a unique manner, each type of connector (8)/electrodes (9, 9'"'"') assembly and automatically indicating to the defibrillating device (1) a connection of the connector (8)/electrodes (9, 9'"'"') assembly and the type of connector (8)/electrodes (9, 9'"'"') assembly connected in a corresponding functioning mode.

5. Defibrillating system according to claim 1, wherein each connector (8)/electrodes (9, 9'"'"') assembly of said plurality of connector (8)/electrodes (9, 9'"'"') assemblies comprises at least an indicator (12) signalling an end of a charging phase and a discharge authorization, and two buttons (13, 13'"'"') or control keys connected to each other in series, allowing a triggering of a defibrillating discharge by simultaneous depression of said two buttons (13, 13'"'"') or control keys.

6. Defibrillating system according to claim 1, wherein said switch is for triggering automatic generation of an electrocardiogram obtained via defibrillation electrodes (9, 9'"'"') adapted to be attached to the patient, said switch being associated with a display (19) signalling a measurement and analysis phase, said electrocardiogram being analyzed by said defibrillating device (1) which, depending on results of said electrocardiogram, decides whether to authorize a carrying out of a defibrillation by automatically triggering a charging operation and which determines one of a value of single charge and values of successive charges on the basis of said results and optional supplementary data input to said defibrillating device.

7. The system of claim 1, wherein said paddle electrode houses one of said first and second control assemblies, and wherein said internal and adhesive electrodes are separate from said first and second control assemblies.
