ABSTRACT:
An improvement in an injection bulb device in an assembly for administration of parenteral solutions is disclosed. The device is a tubular elastomeric member having an enlarged intermediate section whose bore is larger than the bores in the two end sections. A plurality of flat-surfaced projections or rings extend inwardly from the walls of the bores in the end sections which compressively grip the end of a rigid needle adapter and flexible tubing inserted respectively within these end sections. The end of the tubing flares outwardly into the enlarged bore of the intermediate section and this configuration assists in increasing the strength of mechanical engagement between the tubing and the injection bulb.
