Abstract: A flow regulator has a pair of side walls extending generally parallel to one another, a bottom wall connecting the side walls to one another and defining an elongate channel for receiving a compressible tube, a roller rotatably and shiftably mounted to the side walls for rolling along the tube in the channel and compressing the tube against the bottom wall. The bottom wall is provided with a formation which varies from a first end of the channel towards an opposite, second end thereof, whereby compressive force applied to the tube via the roller is different at different longitudinal positions of the roller along the channel. A bracket or bow-shaped bridge is disposed about or between the side walls at one end of the channel. The bracket is in contact with outer surfaces of the side walls only in regions of the side walls spaced from the bottom wall. The bracket or bridge is advantageously made with less inherent stiffness than the assembly defining the elongate channel.

Abstract: An instrument having ergonomic gripping for the comfort and firm gripping by a user. The instrument comprises an elongated body having a uniform rear portion that diverges into two or more arms, which are then merged at the front writing end to form a bulbous front portion for a user to grip. In one embodiment, the two arms diverge from the rear portion defining an opening therebetween wherein a user's thumb is placed against one side of the opening and the middle finger against the opposite side of the opening, with the index finger resting along the curved bulbous front portion for a firm, ergonomic grip. In another embodiment, the instrument comprises a generally teardrop shaped annular body defining an opening therebetween having a concave surface and an opposite convex surface wherein a user's thumb is placed against the opening on the concave surface and the middle finger against the opening on the convex surface, with the index finger resting along the curved teardrop periphery.

Abstract: A combination holding and stabilizing device with reinforcement for cylindrical objects comprises a combination of two components, a securing unit and an anchoring unit. The securing unit has an elongated longitudinal body having a top surface with adhesive and first and second lateral portions extending from a fold line. The second lateral portion foldably overlaps the first lateral portion for holding and stabilizing a cylindrical object therebetween. At both ends of the body, the top surface of the first and second portions have separable holding elements to releasably secure the first and second portions together to allow quick and easy adjustment of the cylindrical object. The securing unit has at least one reinforcement strip embedded in the body for improving the holding and stabilizing power. The plastic strip is malleable and conforms to the shape of the cylindrical object to be held in the securing unit.

The anchoring unit has an elongated longitudinal body having a bottom surface with adhesive. The anchoring unit is longer than the first lateral portion of the securing unit such that the bottom surface of the securing unit is attached to the top surface of the anchoring unit with the anchoring unit extending beyond at least the axis of the fold line.

Abstract: A flow regulator has a pair of side walls extending generally parallel to one another, a bottom wall connecting the side walls to one another and defining an elongate channel for receiving a compressible tube, a roller rotatably and shiftably mounted to the side walls for rolling along the tube in the channel and compressing the tube against the bottom wall. The bottom wall is provided with a formation which varies from a first end of the channel towards an opposite, second end thereof, whereby compressive force applied to the tube via the roller is different at different longitudinal positions of the roller along the channel. A bracket is disposed about the side walls at one end of the channel. The bracket is in contact with outer surfaces of the side walls only in regions of the side walls spaced from the bottom wall.

Abstract: A flow regulator device for intravenous tubing comprises a frame body, a notch on the frame body for attaching an intravenous tube to the frame body, and a first pressure applicator disposed on the frame body and engageable with the intravenous tube for alternately compressing and releasing the intravenous tube in a first direction of action in a first plane. A second pressure applicator is provided on the frame body for alternately compressing and releasing the intravenous tube in a second direction of action in a second plane. The second pressure applicator is disposed on the frame body in spaced relation to the first pressure applicator along a flow path of the intravenous tube and is engageable with the intravenous tube.

Abstract: An intravenous delivery assembly comprises, in accordance with the present invention, a frame member and a plurality of intravenous flow regulators each including (a) at least one attachment element for attaching a respective intravenous tube and (b) flow regulating componentry for varying a fluid flow rate through the respective intravenous tube. Cooperating connectors are provided on the flow regulators and the frame member for removably connecting the flow regulators to the frame member. The flow regulating componentry includes a clamping member having elongate first and second clamping elements and a slider member for shifting the clamping elements alternately towards and away from one another to vary a fluid flow cross-section in an intravenous tube inserted between the clamping elements.

Abstract: A Portable signaling device comprises a housing having a first face and a second face, the housing being provided with a first opening in the first face and a second opening in the second face. The first opening is smaller than the second opening. A lamp is mounted to the housing for motion between a first position in which the lamp is oriented towards the first opening and a second position in which the lamp is oriented towards an interior of the housing. A shifting component is movably mounted to the housing and engageable with a lamp mount for operating on the mount to move the lamp between the first position and the second position. An electric power supply is provided in the housing. Contacts are provided in the housing for operatively connecting the power supply to the lamp at the first position and the second position only. At other positions of the lamp, the lamp is disconnected from the power supply and is therefore de-energized.

Abstract: Apparatus for engaging at least one associated intravenous tube used in the delivery of medication or nutrient to a patient which includes a first generally U-shaped member having first and second generally straight elongated legs. Each of the legs has inner and outer faces. The inner faces are disposed in opposed relation and the first leg is movable between a first position in which the respective inner faces of the first and second legs are disposed in spaced relation and a second position in which the respective inner faces of the first and second legs are closer than in the first position, the inner faces being disposed in the first position with a space sufficient to allow insertion of an intravenous tube therebetween, the inner faces being dimensioned and configured to engage the sides of the associated intravenous tube in the second position.

Abstract: A portable water-resistant device for signaling vehicles such as a taxi is formed of a lightweight, transparent plastic and is battery powered. The signaling device is provided with a first housing, a second housing movable relative to the first housing, the first housing containing a light source and a power source and reflective symbols affixed to the outer face of the first housing. The light source is selectively electrically connectable to a power source, such as a battery, which is activated when the second housing moves relative to the first housing and contact points extending from battery terminals and protruding through the first housing meet with contact points of the second housing. Additionally, in another embodiment the signaling device may be provided with an outer movable housing having a switch, an inner housing containing a light source and a power source electrically connected to the switch, and reflective symbols on the outer face of the inner housing.
