Laryngoscope This laryngoscope consists of a handle with longitudinal grip features, a screw-joint blade, and a light on one side, and a detachable lid on the other. By twisting the lid, one can access the battery. The device was operated by inserting the blade-light joint end perpendicularly into the main handle. The inscription "Rimlock Made in England" can be found on it. Additionally, the number 9 is somewhat haphazardly inscribed on it. The handwritten inscription "Ward 9 C.O.H" is written at the very end. There is no manufacturer's mark present. These are still in use today, as the laryngoscope facilitates the insertion of a tube into the larynx. Prior to this, examination of the larynx was only possible with the aid of a mirror. 1925-1975
