A drip chamber 30 incorporates a charging spigot 24 with a fluid inlet sub-chamber 28 having orifices 34 through which the fluid passes. The flow path through the orifices is off-vertical, preferably horizontal, and the orifice surface area is greater than that of the spigot conduit supplying fluid to the chamber. An outlet 38 at the base of the drip chamber may be vertically in-line with the spigot. The spigot sub-chamber may be cylindrical with a closed end wall 36 and the orifices arranged regularly around its curved surface. Two of the drip chambers may used in parallel to supply fluid to two tubes 12 each having a flow control valve 18 towards their distal end. A Y-junction 20 couples the tubes to a single delivery tube 14 having a flow controller 22 and terminating in a nozzle 44. The arrangement may be used to irrigate a trans-urethral resection of the prostate. |
