The invention relates to a vaginal speculum, to a reusable electric device and to an assembly thereof. The vaginal speculum can be introduced into the vagina. A speculum housing having at least one spoon blade with an opened and closed state are provided. The housing is arranged to allow viewing in the longitudinal direction towards the distal end. A speculum housing part extends in the longitudinal direction. The reusable electric device has one or more functionalities, such as a light or a camera. The electric device comprises a housing with an aperture and circuitry, e.g. comprising a battery, received in the electric device housing. The vaginal speculum and the reusable electric device can share a connection system for releaseably connecting the reusable electric device to the vaginal speculum, the connection system having an insert direction for inserting the reusable electric device, the insert direction extending from the proximal end to the distal end and the connection system arranged to position the reusable electric device in the vaginal speculum housing along said speculum housing part. Further the electric device can have safety features.
