PROJECTILE FOR DELIVERY OF A TRANQUILLISER

摘要

A projectile mainly for drug delivery comprises a tubular body casing (1) which defines a cavity (2) for containment of a tranquillising drug. The casing has an end plug (3) which coaxially supports a hollow needle (4) projecting forward through an ogival nose cap (5). The delivery end (6) of t he needle (4) projects a short way beyond the cap (5). Located around the needl e (4) towards the tip of the nose cap (5) is a gas producing detonator (7) fir ed by an impact fuse (8). Attached to the detonator (7) and the needle (4) is t he neck (9) of an inflatable bag (10) of which an opposed end (11) is attached to the plug (3). Following discharge from the weapon, the bag (10) expands and prevents excess penetration whilst spreading the impact energy over a wide area.
