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. A helmet, comprising: a retention system for securing to a head of a wearer, the retention system including a headband secured within the helmet and adjustable by a ratchet mechanism located at a back of the headband and a plurality of straps arranged so that when the helmet is worn pass across a chin of the wearer, the straps being adjustable by one or more buckles, wherein the helmet is configured so that, when worn, a front of the helmet protects a forehead of the wearer and a back of the helmet is adjacent a nape of a neck of the wearer, the helmet further including a sensor package configured with one or more sensor pads to monitor vital statistics of the wearer when the helmet is worn, a battery, and a telemetry transmitter, wherein the sensor package is detachably secured to the retention system by being positioned on a removable strap that is removably attached to the headband of the retention system.
2. The helmet of claim 1 , wherein the straps are part of a harness adjustable by the ratchet mechanism.
3. The helmet of claim 1 , wherein the one or more sensor pads are arranged to contact a body of the wearer at one or more points on the wearer's body and coupled to input electrical signals to a processor of the sensor package, the processor being 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 a remote monitoring location via the telemetry transmitter.
4. The helmet of claim 3 , 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 sensor package.
5. The helmet of claim 1 , wherein the sensor package includes an accelerometer and the one or more sensor pads are configured to contact a body of the wearer at one or more points on the wearer's body.
6. The helmet of claim 1 , wherein the removable strap is an elastic strap and the sensor package is mounted on the elastic strap.
7. The helmet of claim 1 , wherein the removable strap is a sizeable strap and the sensor package is mounted on the sizeable strap.
8. The helmet of claim 1 , wherein the one or more sensor pads are arranged to contact a body of the wearer near the wearer's forehead when the helmet is worn by the wearer.
9. The helmet of claim 1 , wherein the one or more sensor pads are arranged to contact a body of the wearer behind ears of the wearer when the helmet is worn by the wearer.
10. The helmet of claim 1 , wherein the plurality of straps include cut points.
11. The helmet of claim 1 , wherein the one or more sensor pads are constructed of conductive fabric and configured to contact a body of the wearer at one or more points on the wearer's body.
12. The helmet of claim 11 , wherein the one or more sensor pads are coupled to input electrical signals to a processor of the sensor package, the processor being 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 a remote monitoring location via the telemetry transmitter.
13. The helmet of claim 11 , wherein the one or more sensor pads are coupled to input electrical signals to a processor of the sensor package, the processor being configured to sample the electrical signals input from the one or more sensor pads periodically and to store a record of the sampled electrical signals input from the one or more sensor pads in a writable memory of the sensor package.
