Removed Staples and drain tubes

So 3 weeks post-operation and it was time to get staples removed.  There are two drains-literally, 2 tubes inserted under skin flap to suck blood and other fluids from site of surgery.  The tubes emptied into plastic airtight bulbs, which were emptied twice a day. After emptying bulbs, be sure and push the air out, in order to create suction.  When I left the hospital, the drainage was very blood-red.  The amount of liquid was 10 cc.  for drain#1(morning & night); and 5 cc for drain#2.  By the start of week 3, drain #1 was watery discharge, the amount 5 cc. or less; drain#2 was dry.   Counted 60 staples.  I was surprised that the edges of the wound still had gaps and puckered regions--the surgeon was not concerned.
