摘要:
A fluid delivery device is provided for delivering fluid to a target site such as an intervertebral disc during discography. The fluid delivery device includes pressure and volume sensors to determine the pressure and the volume of the fluid delivered to the intervertebral disc. The fluid delivery device is hand-held during use and includes a syringe assembly having a plunger with threads that enables controlled discharge of the fluid from the fluid delivery device by rotating the plunger in a housing of the fluid delivery device. The fluid delivery device may also include a communication module to wirelessly transfer data to an external device outside of a sterile field, while the fluid delivery device is in the sterile field. The fluid delivery device may also include a physiological sensor to monitor involuntary pain responses based on changing physiological parameters such as increases in body temperature or blood pressure.

A closure assembly that is infinitely adjustable within an operating range of the closure assembly and includes a vent port therethrough. The closure assembly includes a housing and an operator that rotationally cooperates with the housing. A flexible member is movably supported by the housing and cooperates with the operator so that manipulation of the operator alters the amount of the flexible member that extends beyond the housing. A biasing means cooperates with the operator and interacts with the housing to maintain a desired orientation of the operator, and thereby a desired orientation of the flexible member, relative to the housing to define a shape of a closure of the item of apparel. A vent port is formed through the housing and the operator and mitigates heat collection therebehind.

An electrically powered dispenser for paper towels uses a special roller bracket to provide not only proper positioning and support for the drive and pinch roller shafts, but also tension and grounding between the drive and pinch rollers, thereby producing a dispenser that is both reliable to operate and simple to assemble. The mounting bracket is integrally formed from a single sheet of conductive material and preferably includes a pair of side plates connected by a mounting bar which includes an integrally formed tear bar portion for cutting the material after it has been transported past the rollers. Each side plate incorporates a flexible bridge (arm) portion for biasing each of the two shafts against a respective bearing portion to thereby complete a static discharge path from the rollers to the mounting bar without requiring any separate springs, contacts or wires. In a preferred embodiment, a door mounted projection blade assists in proper paper loading, a removable top cover functions as a universal mounting bracket, and flexible paper protection fingers discourage unwanted contact between the paper and the tear bar.

A shutter section includes a stack of circular plates independently rotatable in a nest formed as a laminar formation of rings. The plates have central openings defining a light path. Four central plates in the stack are shutter guide plates with radial guide slots slideably holding shutter blades. Two outer pairs of plates are shutter drive plates connected by cams to the shutter blades. Simultaneous rotation of a shutter guide plate and associated shutter drive plate causes rotation of an associated shutter blade around the light path. Rotation of a shutter drive plate while the associated shutter guide plate is stationary causes the cam to move the associated shutter blade radially. The nest is enclosed by end plates. A motor section has motors driving pinions to rotate the circular plates. The circular plates, rings pinions and shutter blades are made of sheet metal. Shutters may be provided as interleaved pairs each driven by a pair of rotatable drive plates.

The invention provides a system, device and method for localized application of therapeutic substances within a biological conduit. In various embodiments, a dissolvable bag or bolus of at least one therapeutic agent is introduced and pressed and/or sealed against the wall of conduit. In other embodiments, dissolvable barbs formed from at least one therapeutic agent are ejected from a catheter by fluid pressure, embedding in the wall of conduit.

One embodiment of the invention relates to a beverage server for use in containing and dispensing liquid. The beverage server comprises a container, a lid, a stopper, and an actuator coupled to the handle and to the stopper. The actuator moves between a first position and a second position and is configured to move the stopper between an open position and a closed position.
