Type of injection sadly not universal — not quite (11)
I believe the answer is:
intravenous
'type of injection' is the definition.
(as in an intravenous injection)
'sadly not universal not quite' is the wordplay.
'sadly' indicates anagramming the letters.
'not quite' means to remove the last letter.
'not'+'universal'='notuniversal'
'notuniversal' with its last letter taken off is 'notuniversa'.
'notuniversa' anagrammed gives 'INTRAVENOUS'.
(Other definitions for intravenous that I've seen before include "Within one type of blood vessel" , "in vessels carrying claret" , "Within a vein" , "Sort of injection" , "Like emergency feeding" .)
