Speculum for medical instruments |
| abstract |
A light conducting plastics speculum for a medical instrument such as a sigmoidoscope, seen in section at 11 has two coatings 19 and 21 on its interior surface. The coating 19 and a similar coating 20 on the outer surface have a lower index of refraction than the material of the speculum 11 so as to produce internal reflections and reduce light loss and the coating 21 is of an anti-glare material for reducing external reflections to a minimum. <IMAGE> |
