Abstract

A method and system for hand-held medical monitoring is disclosed. The system includes a plurality of EKG capable electrodes, and analog digital converter electrically connected to the plurality of electrodes and having a plurality of channels, a control circuit electrically connected to the analog digital converter, a serial transceiver electrically connected to the control circuit, a first hand-held personal digital assistant electrically connected to the serial transceiver and adapted for wireless communication, and a set of instructions stored on the first hand-held personal digital assistant for receiving measurements from the plurality of electrodes and displaying measurements from one or more of the plurality of electrodes and wirelessly transmitting measurements from one or more of the plurality of electrodes. Preferably, the system and method also provide for a remote hand-held personal digital assistant and wireless contact with the first hand-held personal digital assistant and adapted for remotely receiving the measurements from the first hand-held personal digital assistant and displaying the measurements.

Claims

1. A system for hand-held medical monitoring comprising:

an interface comprising a plurality of EKG capable electrodes, an analog to digital converter electrically connected to the plurality of electrodes and having a plurality of channels, a control circuit electrically connected to the analog to digital converter, and a serial transceiver electrically connected to the control circuit;

a first hand-held personal digital assistant removably connected to the interface through a serial connection electrically connected to the serial transceiver, the first hand-held personal digital assistant being adapted for wireless communication and having a display; and

a set of instructions stored on the first hand-held personal digital assistant for receiving measurements from the plurality of electrodes and displaying measurements from one or more of the plurality of electrodes and wirelessly transmitting measurements from one or more of the plurality of electrodes to a remote location.

2. The system for hand-held medical monitoring of claim 1 further comprising an oxygen sensor electrically connected to the control circuit for measuring oxygen saturation.

3. The system of claim 1 wherein the plurality of electrodes is 10 electrodes and the plurality of channels is at least 12 channels.

4. The system of claim 1 further comprising a second set of instructions stored on the first hand-held personal digital assistant for wirelessly receiving a second set of EKG measurements and displaying the second set of EKG measurements.

5. The system of claim 1 further comprising a remote hand-held personal digital assistant in wireless contact with the first hand-held personal digital assistant and adapted for remotely receiving the measurements from the first hand-held personal digital assistant and displaying the measurements.

6. A method for hand-held medical monitoring comprising:

transducing a plurality of EKG signals in a corresponding plurality of EKG electrodes coupled to a human body;

converting the EKG signals to a digital signal using an analog to digital converter having multiple channels;

receiving the digital signal in a first hand-held personal digital assistant adapted for wireless communication;

displaying EKG measurements corresponding to the EKG electrodes on a screen of the first hand-held personal digital assistant;

wirelessly transmitting the EKG measurements;

wirelessly receiving the transmitted EKG measurements on a second personal digital assistant at a remote location; and

displaying the EKG measurements on the second personal digital assistant.

7. The method of claim 6 further comprising measuring an oxygen saturation signal;

wirelessly transmitting the oxygen saturation measurement;

receiving the transmitted oxygen saturation measurement on a second personal digital assistant; and

displaying the transmitted oxygen saturation measurement on the second personal digital assistant.

8. The method of claim 6 wherein the plurality of EKG electrodes is 10 EKG electrodes.

9. A system for hand-held medical monitoring comprising:

a plurality of EKG capable electrodes;

an interface having an analog to digital converter electrically connected to the plurality of electrodes and having a plurality of channels and a control circuit electrically connected to the analog to digital converter;

a first hand-held personal digital assistant electrically connected to the interface and adapted for wireless communication;

a set of instructions stored on the first hand-held personal digital assistant for receiving measurements from the plurality of electrodes and displaying measurements from one or more of the plurality of electrodes and wirelessly transmitting measurements from one or more of the plurality of electrodes; and

a remote hand-held personal digital assistant in wireless contact with the first hand-held personal digital assistant and adapted for remotely receiving the measurements from the first hand-held personal digital assistant and displaying the measurements.

10. The system for hand-held medical monitoring of claim 9 further comprising an oxygen sensor electrically connected to the control circuit for measuring oxygen saturation.

11. The system of claim 9 wherein the plurality of electrodes is 10 electrodes and the plurality of channels is at least 12 channels.

12. The system of claim 9 further comprising a second set of instructions stored on the first hand-held personal digital assistant for wirelessly receiving a second set of EKG measurements and displaying the second set of EKG measurements.

13. A method for remote medical monitoring, comprising:

transducing a plurality of EKG signals from a corresponding plurality of EKG electrodes coupled to a human body;

displaying a representation of the EKG signals on a display of a first personal digital assistant attached to the EKG electrodes such that a first responder views the EKG signals only on a display of the personal digital assistant;

transmitting EKG measurement from the personal digital assistant over a wireless network to a second personal digital assistant of an health care professional; and

displaying the EKG measurements on the second personal digital assistant for the health care professional, such that the health care professional views the same EKG signals as on the display of the first personal digital assistant.
