From: Deep Bleeder Acoustic Coagulation (DBAC)—part II: in vivo testing of a research prototype system
Milestone | Most challenging problem | Milestone specification | Treatment speed | Device operation | |
---|---|---|---|---|---|
DBAC hemostasis test condition/objective | Slow bleeder injury | Slow bleed in small vessel | 5 ml/min | Achieve hemostasis before 50 % blood loss. Maximum time limit of 30 min | Full automation: start button, cancel button Closed-loop system Minimum of two panels required |
Fast bleeder injury | Fast bleed in large vessel | 100 ml/min | |||
Depth of penetration | Large, fast, deep bleeder | 12.5 cm | |||
Maximum thermal tissue dose | Large, fast, deep bleeder | Thermal lesioning limited to 2-cm sphere centered on the bleed | |||
Maximum thermal skin dose | Skin burn | MTSD ≤ 52 °C |
