Abstract: A contrast fluid delivery method and system includes a multiple-reuse filling section for attachment by conduit to a contrast fluid supply container, and a delivery section that is removably attached to the filling section for delivering contrast fluid held in the filling section to a patient. The filling section includes a main body having a fluid chamber, a contrast fluid filling inlet with a gravity-operated valve, an opening for connecting an operable power syringe, and a contrast fluid outlet fed through a spring-loaded one-way check valve. The delivery section includes a first delivery conduit connected between the contrast fluid outlet of the main body and the fluid inlet of an inline aspirator syringe, and a second delivery conduit connected at one end to a fluid outlet of the aspirator syringe and at the other to a catheter for delivering the contrast fluid to a patient.

Abstract: A replacement button assembly comprises a replacement button, a carrier sheet for securing and carrying the replacement button, a pressure-sensitive adhesive sheet underlying the carrier sheet, and an adhesively removable backing sheet underlying the adhesive sheet. Such replacement button assembly can be easily adhered to a garment after the removable backing sheet is stripped from the assembly. The present invention also provide a process of making the replacement button assembly.

Abstract: A device for stabilizing or leveling an article of furniture is formed of a deformable outer envelope enclosing a second elastically deformable envelope that is substantially filled with a filler material of a plurality of bead-like particles. The filler material particles, which are preferably smooth-surface glass beads, provide fluidic flowability of the filler material so that, when the stabilizing device is inserted and pressed between an underlying support surface and the lower support structure of an article of furniture to fill a space or gap otherwise present between the support structure and support surface, the inner envelope resiliently deforms to accommodate the redistribution of the particles and dynamically fill the gap, thus stabilizing the article of furniture on the support surface.

Abstract: An anatomical display apparatus includes a three-dimensional model simulating at least a portion of a human or animal body and within which is located a body part, region, tissue and/or organ of interest. A plurality of images of the body part, each showing the body part in a different state or condition such, for example, as before, during and/or after a therapeutic treatment, are carried on a movable support disposed within the model. The support is selectively movable under user manipulation or control so as to transport a selected one of the plural images into suitable juxtaposition with an opening or passageway defined in and through the model and thereby permit an observer located externally of the model to view the selected image within the model through the passageway.

Abstract: A liquid or viscous curable adhesive composition having a prolonged pot life which is composed of a liquid or viscous curable resin which has, preferably evenly and randomly dispersed therethroughout, a multiplicity of rupturable microcapsules containing a curing agent in an amount sufficient to cure the resin. The microcapsules are rupturable upon the application thereto of external pressure, or other mechanical manipulation. Upon rupture, the curing agent is released into coacting relationship with the curable resin and forms therewith an activated adhesive composition.

Abstract: A lightweight and portable volumetric spirometer for measuring the volume of and rate of flow of air inhaled by human lungs. The device includes a movable piston within a first transparent cylindrical chamber provided with calibrated markings along its surface for measuring the volume of air withdrawn from the chamber. The first chamber communicates with a breathing tube assembly through which the user inhales. The breathing tube assembly is uniquely adapted so that the inhaled air flow is divided into two fixed portions, one portion of which comes from the chamber, the other portion of which comes from a second chamber communicating with the outside atmosphere. As air is inhaled, the piston rises to a height that can be related to the total volume inhaled. Preferably, there is a counterweight in the second chamber which also rises during inhalation to counterbalance the resistance to movement of the piston and which gives an indication of the rate of inhalation.
