Otocsope  Repair  and  Troubleshooting  


Description  #   Text  Box   Comments  
1   Start:  Otoscope  Troubleshooting           Begin  diagnostic  process  for  a  work  order  on  Otoscope.  
2   Does  the  light  source  power  on  with  battery?   Power  on  the  device  with  battery.  Examine  whether  light  bulb  gives  sufficient  illumination.  
3   Recharge  battery  if  applicable  or  replace  it.           Refer  BTA  skill  set  on  Batteries  to  identify  and  replace  damaged  batteries.  
4   Replace  bulb  if  necessary.                       Refer  BTA  skill  set  on  Lighting/Indicators  to  replace  non-­‐functional  light  bulbs.  
5   Inspect  and  fix  broken  wires  or  bad  connections  between  the  battery  and  bulb.                                        

Inspect  wires  and  connections  from  battery  to  bulb  using  multimeter.  Refer  BTA  skill  set  on  Connections  for  identifying  and  fixing  broken  wires  and  bad  connections.  
6   Does  the  device  use  a  fiber  optic  cable  and  still  the  light  source  doesn’t  power  on  with  battery?  

There  are  two  types  of  otoscopes:  
• Conventional  otoscope  • Fiber  optic  otoscope  If  the  bulb  still  doesn’t  power  on  then  there  might  be  cracks  in  the  fiber  optic  strands.  So  the  unit  might  have  to  be  replaced.  

7   Inspect  for  cracks  in  fiber  optic  strands  and  replace  the  unit  if  necessary.               If  the  illumination  is  not  sufficient  then  inspect  for  cracks  in  fiber  optic  strands.  
8   Is  the  lens  free  from  cracks/defects?   Any  defect  in  the  eyepiece  lens  obstructs  vision  of  ear  canal.  
9   Replace  lens  if  necessary.             Identify  and  replace  with  a  suitable  lens.  
10   Is  the  head  and  handle  connected  properly?   Improper  connection  between  head  and  handle  may  result  in  faulty  operation  of  the  device.  
11   Refer  device  manual  to  assemble  the  parts.   Follow  instructions  in  the  device  manual  to  assemble  the  parts  together.  
12   Block  the  tip  of  speculum  with  finger.   This  test  is  performed  to  detect  any  air  leaks  in  the  device.  Connect  the  pressure  bulb  to  the  connector  in  otoscope  to  perform  this  test.  
13   Apply  pressure  with  insufflator  bulb.   Apply  pressure  continuously  over  a  period  of  time  and  check  whether  it  can  be  felt  at  the  tip  of  speculum.  
14   Is  the  device  free  from  air  leaks?   If  the  flow  of  air  due  to  pressure  is  not  felt  at  the  tip  of  speculum  then  there  is  a  possible  air  leak  in  the  device.  

15   Inspect  and  troubleshoot  the  otoscope  for  any  cracks,  physical  damage.   Inspect  otoscope  for  external  cracks,  damage,  or  dirt.  
16   Perform  preventive  maintenance  on  Otoscope.  Return  device  to  clinical  personnel.  

Otoscope  is  working  properly.  Perform  preventive  maintenance  before  returning  the  device  to  clinical  personnel.
