drainage tube n.
A tube inserted into a wound or cavity to facilitate fluid removal.
The drainage tube to the bilary duct, which connected the intestines to the gall bladder, also failed.
If the drainage tube be in its proper position, pus should be seen to ooze out of it.
The wound was therefore enlarged, some fragments of rib removed, and a drainage tube inserted.
A drainage tube should be inserted for at least twenty-four hours.
The wound is daily syringed with Condy's fluid, the only antiseptic available, and has a drainage tube.
The gentle handling of the tumour and the employment of a drainage tube for the first forty-eight hours diminishes this risk.
The skin wound is then closed and a small dressing is applied to cover the drainage tube on the forehead.
