Abstract

An external defibrillator can include a bump sensor for generating motion information and a bump detector for determining whether the external defibrillator has been subjected to a local bump event. The external defibrillator can transmit wirelessly a data signal encoding resuscitation event data to a second external defibrillator over a wireless communication link between the two devices.

First claim

What is claimed is:

1. A transmitting external defibrillator for transmitting resuscitation event data to a receiving external defibrillator that is separate and distinct from the transmitting external defibrillator, the receiving external defibrillator including a first housing, a first energy storage module in the first housing for storing a first electrical charge, a first defibrillation port for guiding via electrodes the first electrical charge to a person, and a first wireless communication module, the transmitting external defibrillator comprising:
a second housing;
a second energy storage module in an interior of the second housing that stored a second electrical charge;
a second defibrillation port adapted to be coupled to electrodes, and via which the second electrical charge was guided to the person;
a memory in the interior of the second housing adapted to store event data about when the second electrical charge was guided to the person;
a bump sensor in the interior of the second housing, for generating motion information of the second housing;
a bump detector in the interior of the second housing configured to determine whether the second housing has been subjected to a local bump event based on the generated motion information, the local bump event including a physical touching of the transmitting and receiving external defibrillators;
a second wireless communication module in the interior of the second housing; and
a processor in the interior of the second housing configured to, responsive to a determination that a local bump event has occurred, cause the second communication module to establish a wireless communication link with the first communication module,
in which the second communication module is further adapted to transmit a data signal configured to encode the resuscitation event data over the communication link,
the bump detector is further configured to establish a bump confirmation that the local bump event also involved the receiving external defibrillator,
the second communication module is configured to only transmit the data signal responsive to the local bump confirmation being established,
the second communication module is further configured to transmit an availability signal, and
the availability signal is output with a preset time delay after a time of the local bump event.

2. The transmitting external defibrillator of claim 1 , in which
the bump detector is configured to determine that a local bump event has occurred if the motion information is interpreted as representing a deceleration event having a value that is larger than a preset threshold.

3. The transmitting external defibrillator of claim 1 , further comprising:
a user interface, and in which
the user interface is configured to cause a confirmation request to be output responsive to the determination that the local bump event has occurred, and
the second communication module is configured to cause the communication link to be established responsive to receiving from a user a user confirmation in response to the confirmation request.

4. The transmitting external defibrillator of claim 1 , in which
the second communication module is configured to transmit an availability signal, and
the second communication module is further configured to transmit the data signal responsive to the first communication module receiving the availability signal transmitted by the second communication module.

5. The transmitting external defibrillator of claim 4 , in which
the availability signal is adapted to communicate identification information about the transmitting external defibrillator.

6. The transmitting external defibrillator of claim 1 , in which
establishing the communication link includes the transmitting external defibrillator receiving a readiness signal that is generated by the receiving external defibrillator.

7. The transmitting external defibrillator of claim 6 , in which
the readiness signal is adapted to communicate identification information about the receiving external defibrillator.

8. The transmitting external defibrillator of claim 1 , in which
the availability signal encodes a time indication associated with the occurrence of the local bump event.

9. The transmitting external defibrillator of claim 1 , in which
establishing the communication link further includes the transmitting external defibrillator receiving a readiness signal that is generated by the receiving external defibrillator,
a time of a remote bump event of the receiving external defibrillator is determined from the readiness signal, and
the bump confirmation is established by comparing the time of the remote bump event with a time of the local bump event.

10. The transmitting external defibrillator of claim 9 , in which
for the time comparison, the readiness signal encodes the time indication of the remote bump event.

11. The transmitting external defibrillator of claim 1 , further comprising:
a global positioning system (GPS) unit configured to determine GPS coordinates corresponding to the transmitting external defibrillator, and in which
the processor is further configured to cause the second communication module to not establish a wireless communication link with the first communication module based on the GPS coordinates.

12. A transmitting external defibrillator for transmitting resuscitation event data to a receiving external defibrillator that is separate and distinct from the transmitting external defibrillator, the receiving external defibrillator including a first housing, a first energy storage module in the first housing for storing a first electrical charge, a first defibrillation port for guiding via electrodes the first electrical charge to a person, and a first wireless communication module, the transmitting external defibrillator comprising:
a second housing;
a second energy storage module in an interior of the second housing that stored a second electrical charge;
a second defibrillation port adapted to be coupled to electrodes, and via which the second electrical charge was guided to the person;
a memory in the interior of the second housing adapted to store event data about when the second electrical charge was guided to the person;
a bump sensor in the interior of the second housing, for generating motion information of the second housing;
a bump detector in the interior of the second housing configured to determine whether the second housing has been subjected to a local bump event based on the generated motion information, the local bump event including a physical touching of the transmitting and receiving external defibrillators;
a second wireless communication module in the interior of the second housing; and
a processor in the interior of the second housing configured to, responsive to a determination that a local bump event has occurred, cause the second communication module to establish a wireless communication link with the first communication module,
in which the second communication module is further adapted to transmit a data signal configured to encode the resuscitation event data over the communication link,
the bump detector is further configured to establish a bump confirmation that the local bump event also involved the receiving external defibrillator,
the second communication module is configured to only transmit the data signal responsive to the local bump confirmation being established,
the second communication module is further configured to transmit an availability signal, and
the availability signal is output with a randomized time delay within a preset time after the local bump event.
