Frequently Asked Questions
What is the Welch Allyn 22870 otoscope used for?
The Welch Allyn 22870 is a pocket LED fiber optic otoscope for clinical examination of the external auditory canal and tympanic membrane. Used by GPs, pediatricians, emergency physicians, and ENT specialists to assess ear infections, TM perforations, cerumen impaction, and middle ear effusion.
What is SureColor LED technology?
SureColor LED is Welch Allyn's proprietary illumination that provides true-color, daylight-quality light — calibrated to accurately render the pink, grey, and amber tones of the tympanic membrane that are critical for clinical diagnosis. Unlike standard LED sources, it avoids the bluish cast that can mask subtle TM changes. LED lifespan rated at 20,000+ hours.
What batteries does the Welch Allyn 22870 use?
Two AA batteries. The 22870 handle is also compatible with Welch Allyn's rechargeable 71000-A lithium Powerhandle (sold separately) — useful for high-volume clinical settings to eliminate battery costs.
Can the Welch Allyn 22870 perform pneumatic otoscopy?
Yes. The sealed head system includes a dedicated pneumatic port for applying gentle positive and negative pressure — used to assess tympanic membrane mobility, an important clinical test for diagnosing otitis media with effusion (glue ear) in children.
