Abstract: A disposable laryngoscope blade cover that includes a flexible sleeve and a resilient slide band for use in conjunction with a laryngoscope having a blade and a handle. The sleeve has an open end and a closed end. The open end is received by the blade and the handle. The sleeve covers the blade and at least a portion of the handle. The resilient slide band is fixedly attached to the sleeve. The band engages the handle to maintain the sleeve on the laryngoscope. After the cover has been used, the band can be disengaged from the handle for removal of the sleeve from the laryngoscope. The invention is also directed to a method for maintaining the sterility of the cover.

Abstract: A disposable cover is provided for laryngoscopes and the like of the type having an elongate blade with a contoured, channel-shaped guide surface on which an associated light source is mounted to facilitate inserting an endotracheal tube into the air passageway of a patient. The disposable cover comprises a sheath having a sterile exterior surface, and a closed interior surface defining a hollow cavity shaped to receive therein and envelope the laryngoscope blade. The sheath has an open end through which the laryngoscope blade is inserted into the cavity of the sheath. The sheath is readily flexible so that an associated portion of the same can be conformed to the contoured guide surface of the laryngoscope blade. Being constructed from a light-transmitting material, the sheath permits light waves emitted from the light source to pass through the sheath, and illuminate the air passageway of the patient.

Abstract: An aseismic bearing is disclosed for use in a bridge structure in combination with a bridge support and/or sliding bearing. The aseismic bearing permits horizontal movement of the bridge's support to occur under the bridges superstructure while limiting the transmission of those forces to the superstructure. Also disclosed is a displacement control device for limiting relative movement between the two parts of the bridge.

Abstract: A displacement control device for damping relative movement between a structure and a support for the structure, and for absorbing energy when the relative movement exceeds a predetermined amount.
