A Hydrogel Glove for Emergency Ultrasound Screening

Ultrasound without ionizing radiation has been shown to have excellent sensitivity and specificity in the diagnosis of hand fractures, which is used to replace X-ray and CT in the emergency department. The water bath technology further solves the problem of suboptimal contact between the ultrasonic transducer and the skin, but the water flow caused by the movement of the probe produces severe ultrasonic artifacts. In addition, open wounds are not allowed to be placed in the water. In this study, we produce a hydrogel glove with excellent acoustic impedance matching and combine with a scanning device to achieve fast 3D ultrasonography for hands, enabling more rapid and stable programmed emergency ultrasound screening.
