Drainage Tubes

Drainage Tubes are used by surgeons in order to facilitate the discharge of collections of matter, and with the view of keeping open a pathway of escape to the surface for deep-lying collections of pus. Thus in uniting the skin surfaces of an amputation wound a drainage tube is usually inserted in order that there may be no accumulation of discharges pent up in the amputation stump. As the wound gradually heals from within outwards the drainage tube is by degrees withdrawn. Drainage tubes are' commonly made of indiarubber, and are often perforated by holes, so as to afford abundant scope for the escape of inflammatory exudation.
