Abstract

A laryngoscope (1) includes a socket (3) that is mountable on a hand grip, a spatula blade (2) that is coupled with the socket (3) and a light guide tube (4) that has proximal and distal end portions, with the proximal end portion of the light guide tube (4) being releasably mounted in a cavity (11) that extends completely through the socket (3) while the distal end portion engages in a snap-in device on the spatula blade (2). The light guide tube (4) has a completely uniform permanent cross section that improves the laryngoscope spatula (1) since the light guide tube (4) can be manufactured and serviced in an uncomplicated manner.
