Abstract: A movable handle and a power tool. The power tool comprises a housing, a motor supported by the housing and operable to drive a tool element about an axis, and a handle supported by the housing for rotation relative to the housing about the axis. Preferably, the power tool is a circular saw. The circular saw further comprises a switch assembly supported on the handle for movement with the handle and means for connecting the switch to the motor to accommodate movement of the switch relative to the motor. The switch assembly is electrically connectable to the motor and selectively connects the motor to a power source, and the connecting means includes a wiring arrangement. The circular saw further comprises a locking assembly for locking the handle in a position relative to the housing.

Abstract: Apparatus for practicing cardiopulmonary resuscitation (CPR) including a torso, a breast plate, a lung, and a hollow head including a mouth means, the breast plate is mounted pivotally to the torso, the lung resides intermediate the torso and the breast plate and is mounted to the torso and extends into the hollow head member and a second head member mounted to the first head member for sliding arcuate movement with respect thereto to perform jaw thrusts in the practice of CPR. Apparatus simulating the human head. Stackable torsos with breast plates mounted thereto and stackable head members each comprising a portion of a head.

Abstract: CPR manikin in simulated human form including a head, body, arms and legs, the head is provided with throat and mouth openings in fluid communication and the body provided with a cavity, a piston is mounted in the cavity, a disposable lung bag is fastened over and in fluid communication with the throat opening and a body plate is mounted to the body and overlying the piston which provides biasing force to the body plate.

Abstract: A compressible piston (40) is disclosed for use in a CPR manikin to simulate the resistance of the human chest cavity. The piston (40) has a flexible corrugated upper wall (42) to permit compression and a lower rigid wall portion (43) to act as a tactile indicator of the limit of acceptable compression.

Abstract: A valve means (1) is disclosed for use in a teaching manikin to simulate an open and closed airway of the human throat. The valve means comprises a section with a hollow passage and two end openings. A first opening fits onto a manikin head and a second opening seats on a sealing surface. When the head is tilted back the valve means (1) lifts to open the second end to permit the flow of air.

Abstract: An artificial respiration teaching device having in combination a hollow plastic head having mouth and throat openings, an inflatable bag removeably attached about the throat opening and adapted to receive air blown into the mouth of the head and through the throat.

Abstract: A disposable cervical collar having an elongated unitary body formed from plastic core board or similar cellular material, the collar having a frontal section provided with a chin receiving opening, including a chin supporting flap and optionally a chin strap, with a throat opening underlying the chin opening, and a rear section which is slotted at spaced intervals for bending to conform to the wearer's neck, the rear section having a plastic strap adapted to be adhesively secured to the frontal section to secure the collar in place.

Abstract: A cervical collar composed essentially of an anterior section and a posterior section interconnected by an elongated strap, with the rear surfaces of the sections covered by cushioning material, the parts preferably being formed from high density polyethylene sheeting with polyethylene foam cushioning material, the parts being interconnected by plastic fasteners. Preferably the sections will be adjustable relative to each other, with one of the sections slidably mounted relative to the other. The configuration of the sections is designed to provided optimum support to achieve immobilization of the cervical spine.

Abstract: A manikin with a disposable lung is used as a tool for teaching cardio-pulmonary resuscitation (CPR). The manikin includes a head, chest, disposable lung, and compression device. The head includes a "mouth" opening to receive air blown into it by a user, and the chest is removably connected to the head. The disposable lung is removably connected to the head in communication with the mouth opening. The compression device preferably is a resilient dowel like member which extends vertically through the manikin chest, having a stop which positively prevents resilient compression of more than a certain amount.

Abstract: This invention relates to a spineboard and parts thereof adapted for securement and transport of a person who may have suffered a spinal injury. The spineboard consists of a board having at least one longitudinal track adapted to receive in slidable connection at least one body harness and having means to secure a head harness; at least one body harness having a pad adapted to lie over the track and having at least one strapping means adapted to engage the track in slidable connection and to encircle and to secure a person to the board; and a head harness adapted to be located on the board.

Abstract: A spineboard for immobilizing a prostrate patient comprises a body supporting board having a body restraint harness which consists of two lengths of flexible material each having a proximal end retained on the board at or adjacent the center of the width thereof. Each length of the harness has a sufficient extent to extend from the proximal end in a first direction around to the body of the patient to be secured to the board adjacent a side edge of the board remote from the proximal end. The body restraint harness is slidably mounted on the board so as to be positionable at any required point along the length of the patient. The body restraint harness also includes a shoulder harness and a head harness for immobilizing the patient. To facilitate the mounting and release of the distal end of each length of the harness, the side edges of the board are formed with a mounting edge over which hooks located at the end of the harness may hook.

Abstract: A flotation device such as a life buoy comprises a flotation member in the form of a buoyant body of foamed plastic material having a support surface extending about a perimeter thereof. A retrieval member is connected to the flotation member and is in the form of an elongated web. The web is connected to the flotation member in a manner such that it is positioned to be located in an operable position extending from its connection with the flotation member and a storage position extending about the support face.
