Abstract: A stoma measuring device is provided comprising a valve housing containing a valve, a lumen with a port located near its distal end, with the lumen having its proximal end secured to the valve housing, and an inflatable component member, with this member located near the distal end of the lumen, the member having a first end secured to the lumen intermediary the port and the valve housing. The lumen is relatively flexible and may be fabricated with a radiopaque filler. The method for using the device of this invention permits the measuring of the depth of a stoma by inserting the distal end of a lumen through the opening in the stomach, the lumen having a port near the distal end, the lumen also secured to the first end of an inflatable component member, the port being intermediary the first end and the distal end, the lumen also having indicia thereon, inflating the member and ascertaining the relative distance between the first end in the stomach and the outer layer of skin through the use of the indicia.

Abstract: An enteral delivery universal port assembly fabricated from a first portion and a second portion of different materials. The first portion has a generally cylindrical side wall, an annular top surface and a corresponding annular bottom surface. The second portion has a central portion with a peripheral flange extending radially outward therefrom, and an annular portion positionable is superposed adjacent relationship to the annular bottom surface. Extending upwardly from the surface of the central portion are first and second projections, the first projection having a base which is a spikable membrane and the second projection being associated with filter means which allow air to enter the enteral nutritional product container to which the enteral delivery universal port assembly is secured in its operative embodiment.

Abstract: A closure containing an internalized microbial filter for use in enteral delivery set assemblies. The closure comprises a generally cylindrical side wall, a planar top surface having first and second projections, the first projection being associated with the spikable membrane while the second projection is associated with a filter and with means to limit air access to the filter. The closure also includes a bottom surface having an aperture which extends through the closure to the top surface thereof with the filter being secured to the bottom surface and extending across the opening of the aperture.
