<p>A method and apparatus is provided for delivering and/or withdrawing fluids. For example, blood may be salvaged from a body cavity of a patient in which a wand (10) is provided having separate conduits (11, 12) for fluids. Means, for example a valve (16), is provided for opening or closing the desired conduits (11, 12) depending upon whether the fluid is to be salvaged or lost to waste, sampled or returned directly to circulation. The apparatus is adapted for surgical use, and most particularly when a partial vacuum is drawn through the conduits (11, 12), such that operation of the valve (16) can exert a partial vacuum on one or more of the conduits. The entry ends of the conduits are disposed adjacent each other, with the conduits being joined as a wand. The valve is adapted for being actuated upon being held in the hand of the operator.</p> |
