Abstract: A medical infusion pump system includes a clamshell housing, a plate, and a pump. The clamshell housing includes a first shell and a second shell hingedly connected together allowing the housing to be in an open position or in a closed position. The housing defines one open end and an interior space. A plate releasably engages the housing at the open end when the housing is in the closed position. The plate defines an opening communicating with the interior space and includes attachment structure. The pump is removably attachable to the attachment structure of the plate and includes a retaining portion. When the pump is attached to the plate, the retaining portion retains the housing in the closed position.

Abstract: A pressure plate for use with a pump includes a top surface configured for receipt of a tube and a plurality of side edges defining a channel communicating with the top surface. The pressure plate also includes a pair of hooks and a loop for releasably attaching the pressure plate to the pump. Attachment structure is provided for fixedly attaching the first end of the top surface to the pump. A method for attaching to a pump a reservoir having a tube includes providing a pressure plate with first and second ends and having an inlet tube slot and an outlet tube slot for holding the tube; attaching the first end of the pressure plate to the pump using a fastener, the fastener allowing the pressure plate to pivot toward and away from the pump; inserting the tube into the inlet tube slot and outlet tube slot; pivoting the second end of the pressure plate toward the pump; and attaching the second end of the pressure plate to the pump.

Abstract: This invention relates to reusable pressure plates designed to position tubing along a tubing support surface to facilitate peristaltic pumping of fluids from a fluid reservoir to a patient. Preferred embodiments of this invention include reinforced pump anchors to securably but releasably affix the pressure plate to the control module portion of an infusion system and cantilevered spring support to maintain pump accuracy and enabling the use of more durable materials for pressure plate manufacture.

Abstract: Reusable cassettes for a drug pump are disclosed to house a fluid reservoir and tubing extending from the reservoir across a tubing support surface of the pressure plate of the cassette. A hinged housing provides reversible access to the fluid reservoir. Reuse of a portion of the pressure plate is also disclosed.

Abstract: An infusion system having a pumping mechanism with tube-engaging members for pumping fluid through a tube, a releasable pressure plate that can be attached and detached from the pumping mechanism having a releasable attachment mechanism for attaching an infusion tube to the pressure plate such that the infusion tube can be engaged by the tube-engaging members when the pressure plate is attached to the pumping mechanism, and an infusion tube for delivering fluid from a fluid source to a patient that is arranged and configured to be attached to the pressure plate by the attachment mechanism and used with the pumping mechanism. The infusion tube can be quickly replaced by detaching the infusion tube from the releasable attachment mechanism and attaching a new infusion tube to the pressure plate.

Abstract: A pressure plate for use with a peristaltic pump having a base with a plurality of ribs attached to one surface of the base, each rib having a bottom surface, a top surface and an angled surface extending at an angle from the bottom to the top surface. Each rib being attached to the base such that the angled surface of each rib is oppositely disposed from the angled surface of another rib so that a channel is formed between each pair of oppositely disposed ribs. A securing mechanism is attached to the pressure plate to secure a compressible tube and an attachment mechanism is provided for attaching a pump mechanism to the pressure plate. One securing mechanism includes two clamps at opposite ends of the pressure plate with spaced apart retaining lips. Adhesive attachment of the tube to the pressure plate is also provided.

Abstract: The present invention concerns a pump provided with a control module and an attachable fluid reservoir cassette. The control module includes a pumping mechanism for pumping fluid from the fluid reservoir to the patient. The cassette is provided with appropriate indicia to identify differences between a plurality of cassettes. The control module further includes cassette indicia identification structure for identifying indicia on the cassette. One type of cassette identification system includes a projection extending from the cassette and structure associated with the control module which engages the projection. Another type of cassette identification system includes a light reflecting system which utilizes light from the control module and reflected off the cassette. Still other types of cassette identification systems utilize other non-contact switches or sensors to sense indicia on the cassette to identify the cassette from a plurality of cassettes.

Abstract: The present invention relates to a method and apparatus for forming a longitudinally extending keyway portion in a mill roll having a central bore. The keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.

Abstract: A golf training device for a golf player including a hip belt having opposite belt ends, belt closing elements on the belt for holding the belt ends in joined position on the player, an elastic cord having an upper end and a lower end, an elastic cord attachment point on the belt disposed substantially opposite the joined position, and a stirrup attached to the lower end of the elastic cord for receiving a foot of the golf player.The length of the elastic cord is such that the stretched cord extends from the stirrup receiving the player's foot laterally and upwardly over the front and to the rear of the player to its attachment point on the belt thereby creating a rotational torque at the hips of the player which assists the player in maintaining a proper body stance throughout the swing with a club and properly turning the hips as required for a proper swing.

Abstract: A method for forming a longitudinally extending keyway portion in a mill roll having a central bore, in which the keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.

Abstract: The present invention discloses new and useful compounds including methyl p-hydroxyphenyllactate, its analogues, chemical derivatives and chemically related compounds and their use as antitumor agents, as inhibitors of proliferative cell growth and as prophylactic agents to inhibit and prevent cancer and non-malignant cell growth.

Abstract: A conveyor system for use in coal mines and the like for automatically sensing by means of a gob switch positioned above the conveyor belt when a build-up of coal occurs because of an obstruction on the belt, and automatically activating a reciprocable operable ram which pushes the obstacle from the conveyor belt. The ram is electrically operated by means of a drive chain and includes a reversing switch for reversing the direction of ram movement at the point of furthest ram extension. The obstruction removing apparatus may be positioned to push the obstruction in a direction parallel to or transversely of the direction of movement of the second belt.
