Abstract: A tracheostomy tube assembly comprises a tracheostomy tube and a separate collar member which can be removably attached to the tube. The collar member is fastenable around a patient's neck by flexible fastening means. The collar member can be removed from the tube for attaching the flexible fastening means thereto.

Abstract: An ergonometrically designed tool handle has a pair of perpendicularly extending hand grips secured at spaced locations along the handle. The tool handle allows prolonged usage by an individual without back strain. The tool handle includes a plurality of intersecting inclined portions which dispose the hand grips in optimal orientation. In a first embodiment, the tool handle has a distal end dimensioned for engagement with a hollow cylindrical socket on a tool head shank. In a second embodiment, a pair of offset sockets are provided on the handle for removable reception of a pair of tool head shanks. An adapter is disclosed which enables conversion of the dual socketed handle for use with single socketed tools. The adapter also provides an angulated extension of the tool handle. The tool handle is designed for use with interchangeable tool heads which may include a hoe, a shovel, a rake, and a scraper.

Abstract: A shovel includes an elongated cylindrical shaft having a shovel blade removably secured by a pin and socket connection at a first end, and a first D-shaped hand grip at a second opposite end. A split cylindrical clamping collar includes a clamping screw for securing the collar at a selected position around the shaft. A lateral extension member is pivotally mounted to the clamping collar for movement about an axis which extends parallel to a longitudinal axis of the shaft. A second D-shaped hand grip is secured on a free end portion of the extension member. In use, an individual grasps one of the hand grips in each hand and rotates the first hand grip while holding the second hand grip secured to the lateral extension member stationary, to dump the contents of the shovel blade. The shovel handle construction is particularly adapted for use on snow shovels, and allows an individual to work with a minimum of effort and back strain.

Abstract: An adjustable wrench has a stationary jaw formed at an end of a handle. A slidable jaw is mounted for linear reciprocal movement toward and away from the stationary jaw by a worm gear in mesh with a gear rack on the slidable jaw. An axially movable shaft extends through the worm gear. The worm gear is rotatably mounted on the shaft, and restrained against axial movement relative thereto. An inner end of the shaft is slidably received in a recess in the handle, and a coil spring in the recess outwardly biases the shaft. A lever has a first end pivotally mounted to an outer end of the shaft and an intermediate portion pivotally secured to the handle. The slidable jaw may be moved by rotation of the worm gear to a loosely adjusted position and may be firmly tightened into engagmeent with the head of a fastener by manipulation of the pivotal lever. The wrench allows extremely quick engagement and release with the head portions of various fasteners.
