Systems, methods, components, and software for monitoring and notification of vital sign changes

A method for determining initiation of an emergency alarm apparatus to notify a person about another person's injury, wherein said apparatus comprises a detector for detecting an injury of the another person, an alarm apparatus, and a base station located remotely from the detector and used for determining, when said detector detects an injury, whether said emergency alarm apparatus should be initiated to make a notification about the detected injury, wherein the method comprises:

• collecting data using the detector;
• sending data collected by the detector to the base station,
• determining via the base station that a change in the collected data meets a minimum threshold required for notification, and
• sending a command from the base station to the alarm apparatus commanding the alarm apparatus to make a notification.

An apparatus comprising a wearable device, wherein the wearable device includes:

• a circuit-board enclosure having a cradle containing a removable battery, wherein the cradle is in engagement with a transceiver module for contacting a wrist of a person;
• an adjustable strap for encircling the wrist and removably attaching the wearable device to the wrist, the adjustable strap having a first and a second portion sandwiched between a portion of the transceiver module and a portion of the cradle, with one of the adjustable strap portions being an end of the adjustable strap;
• a pulse oximeter for sensing change in a blood-related parameter;
• and
• a transmitter for transmitting the blood-related parameter and the body movement.

An apparatus comprising a wearable device, wherein the wearable device includes:

• a sensor removably attachable to a body of a person for sensing change in a physical body condition of the person;
• a detector responsive to the sensor for determining whether the person is experiencing an emergency medical condition;
• and
• a transmitter for transmitting a signal indicative of the detected emergency medical condition determined by the detector to a computing device,
• wherein the sensor, the detector, and the transmitter are provided on a strap, the sensor, the detector, and the transmitter being sandwiched between portions of the strap, and
• wherein the computing device is provided at a location remote to the person and the wearable device.
