Abstract: A system and method for endotracheal intubation of airways are disclosed. A malleable stylet having a distal end and a proximal end, a charged coupled device (CCD) at the distal end and a transmitter, at or near the proximal end or connected to the proximal end of the stylet with connectors, transmits video to a visualization device comprising a receiver means, a display means, and a display support adapted to be worn on an operator in a position so that the operator can view the display with one eye while simultaneously viewing the airway directly. The display support is typically worn on the head of a physician. A second display can be worn by a student or observer. In some instances, the transmitter means and receiver means are wireless.

Abstract: A pivoting laryngoscope has a power-driven spatula for performing intubation in patients. The laryngoscope includes a handle for gripping the laryngoscope, and a curved spatula blade having one end connected to the handle. The spatula blade is subdivided into a plurality of adjacent, sequentially arranged sections. At least two of the sections are pivotally connected together at a fulcrum. A motorization assembly is located within the handle and is activatable for generating movement. A motion transmission assembly operatively connects the motorization assembly to at least one of the sections for transmitting the movement of the motorization assembly to the section, whereby the section is moved relative to the fulcrum and within a predetermined arc, thereby changing a curvature of the curved spatula blade.

Abstract: An improvement of a fluid submersible laryngoscope including a hollow handle to contain power supply means and a blade to be inserted into a patient's mouth includes a terminal pin carried on an end portion of the handle by a tubular elastomeric body and an insulation disc located between the power supply means and the end of the elastomeric body. The elastomeric body acts as a fluid sealing means to block access of external fluid into the hollow handle whether or not the blade is attached to the handle. The insulation disc defines a bore through which the terminal pin at least partially extends such that attachment of the blade to the handle will cause the terminal pin to move through the bore and contact the power supply means.
