Application of Finger-Mounted Ultrasound Array Probes

Ultrasound is a standard of care for Central Line Placement (CLP). Existing transducers are awkward to use or require a second clinician to image. Fast and easy to use ultrasound guidance is especially important for military applications where every minute can mean a saved life or salvaged limb. Combat use of ultrasound includes CLP, shrapnel detection, identification of bleeders and other injuries. Blacktoe has developed a finger-mounted ultrasound probe prototype. Premlinary work indicates modifications to our existing finger probe can address current issues with CLP. The overall objective of this proposal is to develop a finger mounted ultrasound array probe for vascular access procedures. This work includes detailed product specifications and the development of a working prototype. This work will leverage substantial prior effort. Blacktoe will conduct end user research utilizing our existing prototype and mockups with Trauma Surgeons, Anesthesiologists, Vascular Surgeons, PICC nurses in the settings where they perform line placement procedures. This work will include performing mock procedures on phantoms to understand workflow requirements and product requirements. Based on this research Blacktoe will develop a working prototype finger probe to address the requirements of vascular access procedures.
