Common therapy/data port for a portable defibrillator
First Claim
1. An external electronic physiological instrument for analyzing a patient'"'"'s electrocardiogram and applying a selected therapy based on the analyzed electrocardiogram, the instrument comprising:
- (a) analysis means for detecting an electrocardiogram of a patient, performing an analysis of the electrocardiogram to determine a type of therapy to apply to the patient, and storing data corresponding to the electrocardiogram;
(b) a therapy generator coupled to the analysis means for generation of a therapy signal that may be applied to the patient, the therapy signal being based on the analysis of the electrocardiogram and the determined type of therapy;
(c) communication means coupled to the analysis means for transmitting the stored data to an auxiliary component; and
(d) a port connected to the communication means and to the therapy generator and allowing application of the therapy signal to the patient or transmission of the stored data to the auxiliary component.

Abstract
A portable defibrillator (10) with a common therapy/data port (12). A set of electrodes (34) is connected to the therapy/data port to connect the defibrillator to a patient. If connected to a patient, the defibrillator operates in a normal mode of operation where it analyzes a patient'"'"'s electrocardiogram (ECG), and, if required, applies defibrillation therapy through the port to the patient. A communication cable (42) is connected to the therapy/data port to connect the defibrillator to an auxiliary component (44). If connected to an auxiliary component, the defibrillator operates in a data communication mode of operation where data may be transmitted to and received from the auxiliary component through the therapy/data port. A test cable is connected to the therapy/data port to connect the defibrillator to a test load. If connected to a test load, the defibrillator operates in a user test mode of operation to allow a user to test the operation of the defibrillator. Preferably, the portable defibrillator automatically determines whether it is connected to a patient, an auxiliary component, or a test load.

14. In an electronic physiological instrument having a communication circuit, a therapy circuit, and a port, a method of selecting between a normal mode of operation wherein therapy signals are applied over a plurality of therapy leads coupled between the therapy circuit and the port, and a data communication mode of operation wherein data are transmitted over at least one data lead coupled between the communication circuit and the port, the method comprising:
-
(a) applying a first signal to one of the plurality of therapy leads; (b) detecting a first responsive signal on one of the plurality of therapy leads and entering the normal mode of operation if the first responsive signal indicates that a patient is connected to the electronic physiological instrument; (c) applying a second signal to the at least one data lead if a patient is not connected to the electronic physiological instrument; and (d) detecting a second responsive signal on the at least one data lead and entering the communication mode of operation if the second responsive signal indicates the presence of an auxiliary component. - View Dependent Claims (15, 16, 17, 18, 19, 20)
