An aortic aneurysm carries increasing risk of rupture with growing aneurysm diameter. This condition is typically asymptomatic, so screening and surveillance are essential. Ultrasound and other imaging methods are employed for such monitoring at high accuracy. However, these methods require an expert and are expensive. Aortic aneurysms are considerably under-detected at present and may become even more under-detected in the future as the disease prevalence increases with societal aging. This disclosure present devices that are convenient in use and cost for aortic aneurysm screening and surveillance.

The present application relates to the technical field of infectious disease monitoring, and specifically relates to an infectious disease monitoring method for international ship crew, comprising: calibrating all crew members on the ship to be in a healthy state during a calibration period; collecting the body temperature and SDNN data of all crew members during the calibration period through a monitoring bracelet, and establishing a physiological baseline database of the ship; judging the physiological index abnormality degree of individual crew members; calculating the group abnormality degree according to the physiological index abnormality degree of individual crew members; calculating a risk index according to the group abnormality degree; setting an early warning value, and comparing the risk index with the early warning value; the present application takes the ship as a monitoring unit, adopts individual and group double-index joint determination, and reduces the false alarm rate; as long as the overall biological rhythm of the whole ship appears "resonance", the body temperature and / or SDNN of most people simultaneously rise or fall, even if the number of abnormal people is 0, the existence of the pathogenic risk can be determined, the weak group signal caused by asymptomatic infected persons can be captured, and the early warning effect is improved.
