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. Located around the needle 4 towards the tip of the nose cap 5 is a gas producing detonator 7 fired by an impact fuse 8. Attached to the detonator 7 and the needle 4 is the neck 9 of an inflatable bag 10 of which an opposed end 11 is attached to the plug 3. The rear end of the cavity 2 has a piston 12 the rear end of which communicates through concentric passageways 13 and ducts 14 with the interior of the bag 10. The nose cap 5 is of a readily breakable plastics material or designed to assist retardation. An impact absorbing material may be contained in the nose cap. On impact with a target the detonator 7 is driven back along the needle and fired via the fuse 8 to thus inflate the bag 10 rapidly. The bag 10 expands and prevents excess penetration whilst spreading the impact energy over a wide area. The bag inflation gas bleeds through ducts 14 and passageways 13 to drive piston 12 forward thus delivering the drug through the needle 6.
