Abstract

A modular external defibrillator system in embodiments of the teachings may include one or more of the following features: a base containing a defibrillator to deliver a defibrillation shock to a patient, (b) one or more pods each connectable to a patient via patient lead cables to collect at least one patient vital sign, the pods operable at a distance from the base, (c) a wireless communications link between the base and a selected one of the two or more pods to carry patient data from the selected pod to the base, the selection being based on which pod is associated with the base.

Claims

1. A modular external defibrillator system for treating a patient, comprising:

a base including;

one or more therapy cables;

a therapy module that, in response to an instruction to deliver a defibrillation shock to the patient, outputs defibrillation shock therapy through the one or more therapy cables;

a base transceiver;

a base connector; and

a pod having a unique identifier stored therein and including;

a patient parameter module having one or more sensors that, when attached to or in close proximity to a patient, collect patient data about the patient that includes one or more patient vital signs;

a pod transceiver that, in response to receiving collected patient data from the patient parameter module, transmits some portion or all of the collected patient data to the base transceiver;

a pod connector that releasably mates with the base connector and communicates the stored unique identifier to the base when the pod is mated with the base.

2. The external defibrillator system of claim 1, wherein the instruction to deliver the defibrillation shock to the patient is based, at least in part, on the collected patient data communicated from the pod to the base.

3. The external defibrillator system of claim 1, wherein the patient parameter module includes an interpretative algorithm to analyze the collected patient data and identify a patient condition based, at least in part, on the analyzed collected patient data, the pod transceiver, in response to receiving the collected patient condition, communicates the patient condition to the base transceiver.

4. The external defibrillator system of claim 1, wherein the pod connector automatically communicates the stored unique identifier to the base when the pod is mated with the base through either a direct connection or a wireless connection.

5. The external defibrillator system of claim 4, wherein the pod connector automatically communicates the stored unique identifier to the base when both the base and the pod are first powered up.

6. The external defibrillator system of claim 1, wherein the pod includes an attachment element that releasably attaches to a gurney.

7. The external defibrillator system of claim 1, wherein the base further includes a user interface electrically coupled or wirelessly coupled to the therapy module and the base transceiver.

8. The external defibrillator system of claim 7, wherein the user interface, upon receiving user input, generates user input data and transmits the user input data to one or both of the therapy module and the pod.

9. The external defibrillator system of claim 1, wherein the base further includes a locator button that, when actuated, generates one or both of a visual or audible alert related to either or both of the base and the pod.

10. The external defibrillator system of claim 1, wherein the base further comprises a sensor electrically coupled or wirelessly coupled to the base transceiver, the sensor generates sensing information related to one or more other pods within the proximity of the base when the sensor either receives a signal from one or more other pods through the base transceiver or sends a signal to discover one or more other pods through the base transceiver.

11. A modular external defibrillator system for treating a patient, comprising:

a base including;

a therapy module that, in response to receiving an instruction to deliver defibrillation shock to the patient, outputs defibrillation shock therapy through one or more therapy cables; and

a wireless base transceiver; and

a pod having a unique identifier stored therein and selectively attached to the base, including;

a patient parameter module having one or more sensors that, when attached to or in close proximity to the patient, collects patient data about the patient that includes one or more patient vital signs; and

a wireless pod transceiver configured to transmit some portion or all of the collected patient data to the wireless base transceiver.

12. The external defibrillator system of claim 11, wherein the instruction to deliver defibrillation shock therapy to the patient is based, at least in part, on the collected patient data wirelessly transmitted from the pod to the base.

13. The external defibrillator system of claim 11, wherein the patient parameter module includes an interpretative algorithm to analyze the collected patient data and identify a patient condition base, at least in part, on the analyzed collected patient data, the wireless pod transceiver configured to transmit the patient condition to the base receiver.

14. The external defibrillator system of claim 11, wherein the pod automatically communicates the stored unique identifier to the base when both the base and the pod are first powered up.

15. The external defibrillator system of claim 11, wherein the pod includes an attachment element that releasably attaches to a gurney.

16. The external defibrillator system of claim 11, wherein the base further includes a user interface electrically coupled or wirelessly coupled to the therapy module and the wireless base transceiver.

17. The external defibrillator system of claim 16, wherein the user interface, in response to receiving user input, generates user input data and transmits the user input data to one or both of the therapy module and the pod.

18. The external defibrillator system of claim 11, wherein the base further includes a locator button that, when actuated, generates one or both of a visual or audible alert related to either or both of the base and the pod.

19. The external defibrillator system of claim 11, wherein the base further comprises a sensor electrically coupled to the wireless base transceiver, the sensor generates sensing information related to one or more other pods within the proximity of the base when the sensor either receives a signal from the one or more other pods through the base transceiver or sends a signal to discover the one or more other pods through the base transceiver.

20. A modular external defibrillator system for treating a patient, comprising:

a base having;

means for delivering defibrillation shock therapy to the patient;

means for sending and receiving wireless transmissions; and

a pod configured to be releasably attached to the base, having;

means for collecting patient data about a patient, the collected patient data including one or more patient vital signs;

means for sending and receiving wireless transmissions between the pod and the base; and

means for identifying the pod stored thereon and automatically transmitting the stored pod identity to the base when the pod and the base are first powered up.
