Evaluation of the Potential for Injury With Remote Drug‐Delivery Systems

摘要: Abstract We evaluated the potential for different types of remote drug-delivery systems (RDDS) to injure target animals. recorded dart velocity, time, and distance from projector muzzle at 8.5-millisecond intervals by Doppler radar chronograph 4 RDDS. used darts volume unique combinations charges, power settings, distances in accordance manufacturer's recommendations. Variation drop repeated shots was >10 cm 28 90 trials (5 replicates per trial) with heavy-mass having lowest precision. Impact velocities were high (>50 m/sec) many using heavy some light-mass, rapid-injection darts. permanent wound cavity (PWC) formed firing dye-filled into ordnance gelatin covered tightly a fresh elk hide thighs calf carcasses. Rapid-injection fitted end-ported needles consistently 1) forced hair skin beneath hide; 2) PWC that 2–3× needle ...
