Table 3.
Engineering metrics for a field-based device for the administration of adjunctive therapies for SBE. The identified units and the corresponding reasons for the choice of those units are provided. The (*) indicates that SC administration is ideal, but may involve IM administration depending on bite location.
Metric | Ideal Units | Reason |
---|---|---|
Volume Injected | 2–5 mL | Encapsulate venom 0.1–2.0 mL |
Dia. Injection Bolus | 3–5 cm | Majority of inter-fang distance |
Depth Injection Bolus | 0.5–2 cm | Majority of fang length |
Needle Depth | 0.5–1 cm | Subcutaneous* injection |
Time to Inject/Deliver | 10–300 s | Patient compliance |
Shelflife | 1–5 yr | Stable to heat/moisture |
Device Width | <8 cm | Hold in adult hand |
Device Length | <30 cm | Easily Packable |
Device Weight | <300 g | Ease of transport, use |
# steps to use | 2-5 steps | Simplicity |
Power | Mech. | No external power required |
