Abstract: A device suitable for direct visual examination and sample collection from the digestive tract and vagina. The device comprises a main body and an observation channel situated inside the main body comprising a first closed end and a second end. The device further comprises an obturator for insertion into the main body, the obturator comprising a longitudinal groove arranged to accommodate the observation channel and a tip comprising a resiliently deformable portion. The resiliently deformable portion is adapted to deform to allow the obturator to pass over the observation channel as the obturator is being inserted into the main body and to restore to its original shape once the tip has passed over the observation channel and the obturator is fully inserted into the main body.
