摘要：
We describe a device, in embodiments a medical device such as a battlefield triage device,configured to be attached to and carried by a person, the device comprising an attachable sensor module, to attach to a person's face, the module having a respiratory sensing region comprising an air temperature sensor and a humidity sensor arranged such that, when the module is attached, airflow in and out of the person's lungs flows over said respiratory sensing region, the module further bearing an optical heart sensor arranged, when the module is attached, derive to an optical heart rate sensing signal from flesh of the person；a signal processing system,coupled to said sensor module,to process and combine signals from said temperature sensor and said humidity sensor to determine a respiration rate for said person and to process signals from said optical heart rate sensor to determine a heart rate of said person； a data output system, coupled to said signal processing system, to output data indicating one or both of said respiration rate and said heart rate. In some preferred embodiments the sensor is arranged to clip to the person's nose (or mouth).The respiratory sensing region is arranged such that airflow in and out of the person's lungs via the nostril flows over the respiratory sensing region and heart rate is sensed from the flesh of the nostril.
