In order toprevent the tube from slipping into thecavity it is draining, a safety pin isfastened to its protruding end in the manner shown in Fig. 143. The pin should be pushed throughthe side of the tube and not cross the caliber of the tubing at itscenter to avoid obstruction of the flow of discharges. The protrusion of the tube beyond the skin should be as slightas possible, just sufficient to allow for the safety pin and a pad.

This precaution avoids oblitera-tion of the end of the tube by pressure from the protective dressing(Fig. 144). The object of the gauze pad is to prevent contact ofthe pin with the wound, which might cause irritation if this pre-caution were not taken.
