  1. 1
    I claim:1. A nursing unit comprising a hollow sleeve member having a tapered tubular wall, means in said wall permitting visual observance of the sleeve, contents throughout a major portion of the sleeve length, a circular groove on the interior sleeve wall adjacent one end of said 55 sleeve and generally concentric with the sleeve, a nipple ° holding assembly including wall means having a first open end and a threaded second open end defining a flow path from the first open end to the threaded second open end and a threaded ring member threadable θθ on said second open end for sealingly securing a nipple against said second open end, said first end of said wall means being of a size and configuration for insertion within the first end of said sleeve member, an elongate flexible retractile liquid impervious bag member having 6g an open end and capable of containing liquid, a circular rib on the exterior surface of said wall means intermediate said first and second ends for tight fit engage- ment with said groove responsive to insertion of said nipple holding assembly by its first end into the narrower end of said sleeve with a wall thickness of said bag therebetween, means for guiding said nipple holding assembly by its first end into the open bag end, said bag being of a size and configuration for generally conforming to the sleeve interior surface over said portion of the sleeve length with the bag open end coextensive with the first end of said sleeve and secured in open disposition between said rim and groove for fluid communication of said flow path with the bag interior, scale means along said portion of said sleeve correlated with, volumetric liquid contents of said bag relative to both ends of said bag with said bag disposed in said sleeve, and a plurality of openings through said wall means between said rib and first end and extending to said rib for defining a flow path for fluid through said wall means.
  2. 2
    In a nursing device, a tubular member defining a conduit having first and second open ends, means for mounting a nipple across said second open end, said tubular member comprising wall means extending from said first open end to said second open end and including a portion intermediate said first and second open ends and a bag receiving element for receiving an open edge of a bag at said first open end and directing the open edge to said intermediate portion with said wall means extending within said bag, and separate drain port means in said wall means spaced from said first open end and adjacent said intermediate portion defining a flow path into said conduit through said wall means.
