A door lock assembly comprising a housing that is received in a mortise in the door with a bolt that is retractable into the housing to permit opening of the door and extendable from the housing to secure the door in its closed position. The bolt has a first portion received within the housing. A second portion is pivotally attached to the first portion so that the second portion can pivot with respect to the first portion when the bolt is extended from the housing, thus permitting opening of the door without the use of a key or rotation of a doorknob. A latch mounted within the opening of a door frame is selectively moveable from a first position engaging the second portion of the bolt when the door is closed in order to prevent the second portion of the bolt from pivoting with respect to the first portion, thus locking the door in the closed condition. When the latch is moved to its second position the second portion of the bolt can pivot with respect to the first portion to allow the door to be opened.

A fiber optic probe protector for protecting a fiber optic probe such that sterilization of the probe after each use is not necessary. The fiber optic probe protector includes a sheath, a window and a handle. The sheath defines a tubular configuration, a first end, and a second end and the window is mounted in the first end of the sheath. The handle defines a first end, a second end, an interior cavity and a locking means. The second end of the sheath is mounted to the first end of the handle and the interior cavity of the handle and the sheath provide a passage for a fiber optic probe therethrough such that the face of the probe abuts against the window. The locking means locks the fiber optic probe in position. The fiber optic probe protector also includes a vacuum assembly which when hooked to a vacuum removes secretions or fluid from the surface to be analyzed with the probe.

A disposable laryngoscope blade connects to a handle especially to facilitate endotracheal intubation of a patient. The blade includes a base portion that attaches to the handle, and an elongated blade portion extends from a proximal end to terminate in a distal tip. The blade portion is arcuate and flattened so as to have a flat upper wall and a flat lower wall joined at lateral edges, and the lateral edges converge toward the distal tip. The blade includes a passageway therethrough so that a vacuum source may attach to a nipple near the proximal end and an inlet port is formed near the distal tip so that fluids may pass through the blade portion. The handle carries a battery power source and electrical contacts. The base portion of the blade also has contacts so that, when the blade is mounted a circuit is completed to power a light source disposed on the blade portion. The blade is preferably formed of two separate plastic pieces joined along a plane perpendicular to the flat upper and lower surfaces of the blade portion to create a housing for the light source and its electrical leads as well as the fluid flow passageway. The base portion has a breakaway latch that engages a notch in the handle so that removal of the blade from the handle breaks the latch structure thereby inhibiting reattachment to the handle.

A conveyor assembly follows a pathway defined by a supporting framework, wherein the pathway may include serpentine portions. The framework supports a transport mechanism for movement along the pathway, and a belt assembly is carried by the transport mechanism. The belt assembly includes a continuous belt having flexible convolutions permitting the belt to follow serpentine portions of the pathway and also permitting the belt to locally laterally tilt for side discharge without requiring the transport mechanism to similarly tilt. A pivotal member between the transport mechanism and belt assembly permits the belt to tilt laterally, such as on a hinge point laterally offset from the center of the conveyor pathway. An actuator causes a selected portion of the belt to tilt on the hinge point. A suitable actuator includes a camming member located on the opposite lateral side of the supporting framework from the hinge point, and the belt assembly may include a tiltable arm extending over the camming member for interacting contact. The camming member may be longitudinally movable for varying the longitudinal position of discharge and also be vertically movable for varying the degree of tilt imparted to the arm and, in turn, to the belt assembly. The inverted return run is provided with a retaining rail to prevent the belt assembly from tilting under force of gravity.
