Patent number: 11166628Abstract: Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.Type: GrantFiled: May 10, 2019Date of Patent: November 9, 2021Assignee: Physio-Control, Inc.Inventors: Robert G.
