  • Publication number: 20140135583
    Abstract: Intubation device consisting of a flexible tube with a distal rubber-like pouch, wherein the pouch cavity communicates with the tube on one end. The other end of the tube is connected to a pressure sensor with light indicator. When it is squeezed it will compress the volume of the chamber and it displaces the air in the tube to trigger the pressure sensor in the proximal end to turn on the light indicator. When the external pressure on the pouch is released, the light indicator is off. The intubation guide has a handle and a curved blade. The tracheal tube follows the curve of the blade held by a tab that is pulled out when the user wants to release the tube. The tip of the introducer is aligned with the tip of the blade and has a light beam directed to the tip of the blade indicating blade location.

  • Patent number: 7909759
    Abstract: A handheld penknife-like laryngoscope including a handle having an electrically insulating rigid plastic blade support section and a battery compartment section for housing a power source with a pair of opposite polarity terminals including a first terminal adjacent the blade support section and a second terminal remote therefrom, and an electrically conducting metal blade non-detachably pivotally hinged on the blade support section for manipulation from an inoperative storage position co-directional with the handle to an operative intubation position perpendicular thereto. The blade tapers towards a tip and has a light source there toward with a first electrode in electrical contact with the blade and a second electrode in electrical contact with the second terminal. The laryngoscope includes a blade retaining mechanism for securely retaining the blade in the intubation position whereupon the blade is in electrical contact with the first terminal for energizing the light source.

  • Publication number: 20100191062
    Abstract: A laryngoscope adaptor cap for use with existing government issue military flashlights designed for use in night time battlefield conditions. A filter disc filters out visible light and a light seal design prevents leakage of visible light from an assembled laryngoscope. The adaptor cap is crush resistant, impact resistant, has a high melting temperature, is disposable and allows the attachment of conventional laryngoscope paddles. It allows for night time endotracheal intubation in conjunction with military issue night vision goggles in the absence of visible light.
