Systems for personal portable wireless vital signs scanner
Methods, systems, and apparatus for periodically and simultaneously scanning for a plurality of vital signs of a user is disclosed. The system includes a personal portable wireless vital signs scanner having a pair of electrodes to form a circuit with a user's body; and a personal wireless multifunction device wirelessly in communication with the personal portable wireless vital signs scanner. The personal portable wireless vital signs scanner includes a processor to concurrently scan for a plurality of vital signs. Some methods include squeezing a personal wireless vital signs scanner between first and second fingers to connect to a first electrode; and pressing the wireless vital signs scanner against a forehead to form a circuit through the body of the user with the personal wireless vital signs scanner. The wireless vital signs scanner may also be pressed against a chest to form a second circuit through the body of the user.
1. A method of scanning vital signs data of a user, the method comprising:
gripping a personal wireless vital signs scanner between first and second digits of the user's hand and connecting one of the first and second digits to a first electrode of the scanner;
pressing a second electrode of the vital signs scanner against the user's forehead and forming a first circuit between the first and second electrodes through the user's body;
activating a first scan of the vital signs scanner on a portable wireless multifunction device wirelessly connected to the vital signs scanner;
in response to activating the first scan, collecting a first set of vital signs data from the user's forehead using the vital signs scanner;
after collecting the first set of vital signs data, selecting to perform a second scan using the vital signs scanner on the multifunction device;
after selecting to perform the second scan, moving the vital signs scanner from the user's forehead and pressing the second electrode of the vital signs scanner against a different portion of the user's body and forming a second circuit between the first and second electrodes through the user's body, wherein the different portion of the user's body is different from the forehead, the first digit, and the second digit;
activating the second scan of the vital signs scanner on the multifunction device;
in response to activating the second scan, collecting a second set of vital signs data from the different portion of the user's body using the vital signs scanner;
transmitting the collected first and second sets of vital sign data to the multifunction device; and
displaying a portion of the collected first and second sets of vital signs data to the user on a display of the multifunction device.
2. The method of claim 1 , wherein collecting the first set of vital signs data includes collecting data for a first time period, and collecting the second set of vital signs data includes collecting data from a second time period, and wherein, the first period of time is between one and ten seconds, and the second period of time is between ten and thirty seconds.
3. The method of claim 1 , wherein
pressing the second electrode of the vital signs scanner against the user's forehead includes
contacting at least one light emitting diode (LED) and at least one photodiode of the vital signs scanner near the user's forehead, wherein the at least one light emitting diode is configured to radiate an LED light onto the user's forehead and the photodiode is configured to receive a reflected LED light from the user's forehead and generate a signal used to obtain a measure of pulse oximetry.
4. The method of claim 3 , further comprising
shading the at least one photodiode from the at least one light emitting diode (LED) to avoid directed light therefrom impinging on the photodiode.
5. The method of claim 1 , wherein
the different portion of the user's body is the user's chest.
6. The method of claim 1 , wherein gripping the vital signs scanner between first and second digits of the user's hand includes gripping the vital signs scanner between a thumb and a forefinger of the user's left hand.
7. The method of claim 1 , further including using microphones in the vital signs scanner to record body sounds of the user.
8. The method of claim 1 , wherein the portable wireless multifunction device is one of a smart phone, a tablet computer, or a portable music player.
9. The method of claim 1 , wherein activating the second scan of the vital signs scanner on the multifunction device includes activating the first or second scan using a user interface button of a software application in the multifunction device.
10. The method of claim 1 , wherein the collected first or second set of vital signs data includes at least one of ECG, heart rate, breathing rate, temperature, blood pressure, or blood oxygenation.
