Head-worn remote informatics system
An informatics system that can be head-worn under a helmet and used to provide a wearer's vital statistics and other information to a remote monitoring station, for example in connection with pre-hospital emergency care.
1. An informatics system, comprising:
a helmet having a ratchet-based helmet retention system for securing the helmet to a head of a wearer, the ratchet-based helmet retention system including a ratchet adjustment mechanism and a harness portion;
a sensor package configured for monitoring of a wearer's vital statistics, the sensor package positioned on a strap that is removably attached to the ratchet-based helmet retention system and configured to be worn about a circumference of the head of the wearer, wherein the strap is not part of the ratchet-based helmet retention system, but instead is removably secured to the harness portion of the ratchet-based helmet retention system; and
a telemetry transmitter communicably coupled to the sensor package and configured for transmitting information from the sensor package to a remote monitoring location.
2. The informatics system of claim 1 , wherein the sensor package comprises one or more sensor pads configured to contact a wearer's body at one or more points on the wearer's body, the one or more sensor pads coupled to input electrical signals to a processor of the informatics system configured to sample the electrical signals input from the one or more sensor pads periodically and to transmit a record of the sampled electrical signals input from the one or more sensor pads to the remote monitoring location via the telemetry transmitter.
3. The informatics system of claim 2 , wherein said processor is further configured to store the record of the sampled electrical signals input from the one or more sensor pads in a writable memory of the informatics system.
4. The informatics system of claim 2 , further comprising a power supply included within the ratchet-based helmet retention system.
5. The informatics system of claim 2 , further comprising an accelerometer coupled to provide an input to said processor.
6. The informatics system of claim 1 , wherein the strap is an elastic strap and the sensor package is mounted on the elastic strap.
7. The informatics system of claim 1 , wherein the strap is a sizeable strap and the sensor package is mounted on the sizeable strap.
8. The informatics system of claim 1 , wherein the strap is removably attached to the harness portion of the ratchet-based helmet retention system with hook and loop fasteners.
9. The informatics system of claim 1 , wherein the strap is removably attached to the harness portion of the ratchet-based helmet retention system with snaps.
