ANo^0mbe?hia9™'  )    Applying  Carrel-Dakin  Solution.  511 
In  order  to  avoid  the  necessity  of  erecting  a  wooden  framework 
over  the  bed  of  the  patient  as  a  means  of  support  which  is  necessary 
when  using-  other  forms  of  apparatus,  a  small,  strong,  portable,  col- 
lapsible stand  has  been  devised  which  can  readily  be  attached  to 
bed-posts  of  any  size  by  means  of  the  device  indicated  in  Fig.  6  (k) 
without  danger  of  disfiguring  the  bed-post. 
As  will  be  noted  from  Fig.  6  the  caloris  bottle  may  be  raised  or 
lowered  independently  of  the  clamps  which  engage  the  bed-posts 
by  means  of  the  thumb  screws  (a1)  (b1)  (c1).  It  can  also  be  seen 
in  this  figure  that  the  outermost  tubular  section  (a)  of  the  support 
has  attached  near  its  ends  two  metal  strap  lugs  (i)  which  in  cross 
section  conform  generally  to  the  contour  of  the  bed-posts  and  are 
provided  near  their  edges  with  vertical  slots  (i1),  Fig.  7,  through 
which  the  straps  (k)  made  of  webb  belting  are  passed  before  being 
wound  about  the  bed-post  (h),  Fig.  8,  and  fastened  by  means  of  the 
buckle  (k1). 
Supplying  Solution  Directly  to  Wounds. — After  the  col- 
lapsible stand  has  been  attached  to  the  bed-post  and  the  apparatus 
has  been  adjusted  for  use  a  gauze  bandage  is  stretched  from  the 
middle  of  the  stand  to  the  opposite  end  of  the  bed.  This  acts  as  a 
support  for  the  connecting  tubes.  (See  Fig.  4A.)  The  tubes  are 
coiled  around  the  bandage  to  points  directly  over  the  wounds  to  be 
supplied  wTith  the  solution.  From  these  points  the  connecting  tubes 
descend  vertically  to  the  instillation  tubes.  This  simple  device  en- 
tirely eliminates  the  necessity  for  building  a  wooden  framework 
over  the  bed  as  is  required  with  many  of  the  other  appliances  and 
permits  the  adjustment  of  the  instillation  tubes  to  any  angle  or  loca- 
tion as  referred  to  above. 
If  the  splendid  results  obtained  by  Carrel  are  to  be  repeated  by 
others,  the  technic  must  be  vigorously  carried  out  and  the  solution 
used  must  be  very  carefully  prepared.  It  has  been  estimated  that 
the  "Dakin"  solution  represents  but  twenty  per  cent,  of  the  cure 
and  the  technic  of  Carrel  represents  eighty  per  cent.  It  is  believed 
that  the  apparatus  herein  described  will  aid  very  materially  the  be- 
ginner in  the  technic  of  wound  sterilization.
