Abstract: An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel medicament dose dialing feature that allows the user to dial in the appropriate dose to be delivered to the patient. Additionally, the apparatus includes a fill assembly comprising a field fill vial that can be readily filled in the field.

Abstract: A children's play apparatus which includes a specially designed play table that can be used with commercially available toys including toy trains and train tracks, and one that can also be used with specifically designed modules for supporting sections of wooden train track in the unique configurations. More particularly, in using the play apparatus, the specially designed modules of the invention can be used to extend the track beyond the boundaries of the play table and which, due to the stackability of the modules can also be used to attain virtually unlimited track heights above the surface of the table and outwardly from the surface of the table top.
