The aspirator I'd ordered as medical specialist (14)

I believe the answer is:

radiotherapist

'medical specialist' is the definition.
(I know that radiotherapist is a type of medical specialist)

'the aspirator i'd ordered' is the wordplay.
'ordered' is an anagram indicator.
'the'+'aspirator'+'id'='theaspiratorid'
'theaspiratorid' is an anagram of 'RADIOTHERAPIST'.

'as' is the link.

I've seen this clue in The Times.
