Abstract
The invention relates to a piercing pin (10) for perfusion purposes to pierce the resilient capsule of a bottle and allow liquid to flow from the bottle (44) to a perfusion system. The piercing pin (10) for perfusion purposes is constituted by a pin body (30) having a longitudinal projection (36) including at least one internal duct (37a, 37b), and piercing means (20) including an internal duct (25) extending said internal duct (37a, 37b) of the longitudinal projection (36), said piercing means (20) are removable and are connected to said longitudinal projection (36) by temporary fastening means (28, 38) for transmitting piercing force to said longitudinal projection (36) and for coming apart from said longitudinal projection (36) when the pin is withdrawn from the bottle. The piercing pin can thus be used once only.
