Sign of injury, with nobody removing ring when entering hospital device (7)
I believe the answer is:
scanner
'entering hospital device' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'sign of injury with nobody removing ring' is the wordplay.
'sign of injury' becomes 'scar' (I've seen this before).
'with' means one lot of letters goes inside another.
'nobody' becomes 'none' (not a single person).
'removing' is a deletion indicator.
'ring' becomes 'O' (letter resembling a ring).
'none' with 'o' taken away is 'nne'.
'scar' enclosing 'nne' is 'SCANNER'.
'when' is the link.
Can you help me to learn more?
(Other definitions for scanner that I've seen before include "Digitiser; hospital machine" , "Medical camera" , "Document converter" , "Imaging and reproductive device" , "Imaging machine" .)
