Signos portable ultrasound device

Made by Signostics Pty Ltd in Australia, Oceania, 2011.

This Signos hand-held ultrasound device consists of a probe connected by cable to a data processing and display unit. While similar devices have many piezoelectric crystals that emit and detect ultrasound waves, the Signos probe contains only one crystal. Accelerometers signal changes in the position of the probe as it’s moved across a patient to create a high definition image on the screen.

Designed by Design + Industry and Signostics Pty Ltd in 2009-2010, and made by Signostics Pty Ltd in Australia in 2011.

The Signos system comprises an ultrasound probe connected via a power/data cable to a Data Processing Unit (DPU) for controlling and instantly displaying the high resolution captured images. The probe features a rapid interchangeable transducer system enabling different types of scans to be conducted via connection of specific transducer heads. The system is wearable using the data cable to hang over the neck, replicating the benefits of portability and convenience of the traditional stethoscope.

The Signos' unique single transducer integrates position sensing technology to produce high resolution images without the need for an array transducer or a motor. The user generates these images by manually "painting a picture" of the underlying anatomy.

Images are stored automatically to the supplied microSD card. Images can be downloaded through a USB connection using SigViewer software and displayed on a computer and exported to be included with a patient record software package. The device features a microphone for recording supplementary notes and an inbuilt speaker for playback.

The device is designed to be completely serviceable with highest wear parts such as transducer cap and connector door replaceable extending the products life. Software upgrades can extend usable life by adding functionality (product grows in capability). No hazardous materials are used in its construction. Designed to be as easily disassembled as practical.
