Rubber for baby bottle nipples, pacifiers, & syringe plungers

An apparatus for maintaining a patient's upper airway clear by removing fluid secretions through such patient's oropharynx and nasopharynx, said apparatus including:

• power driven first means for generating suction at an input port thereof;
• flexible connecting tube means having a first end operatively connected to said input port, and a second end remote from said first end;
• removable nozzle means operatively connected to said second end;
• said nozzle means being operatively constructed to be operatively positioned and maintained manually at oropharynx and nasopharynx openings for suction removal of fluid secretions therethrough;
• said nozzle means being operatively constructed and proportioned relative to such openings to permit no more than minimal insertion of the nozzle means through such openings;
• and said nozzle means including a flange having at least one aperture therethrough, said flange being located adjacent said removable nozzle means for partially blocking air flow into and out of said oropharynx and nasopharynx openings during said suction removal, wherein the nozzle means is comprised of neodymium polyisoprene rubber.

A stopper for sealing infusion bottles containing pharmaceutical liquids, which stopper has a collar, which projects into the opening in the neck of the container and has a diameter greater than the neck opening;

• an edge, which rests on the neck of the container;
• and a puncture area, enclosed by the edge and the collar, the stopper being held on the neck of the container by a protective cap of metal or plastic, characterized in that the top surface of the puncture area is lower than the top surface of the edge, and in that the bottom surface of the stopper inside the collar as well as the top surface of the puncture area are relatively flat, and in that a transverse plane formed by end surface of container neck passes through approximately the center of the vertical thickness of the puncture area, and wherein the length of said collar is generally the same as the cross sectional thickness of the puncture area, the puncture area having a predetermined elasticity and flexibility with respect to the edge and the collar whereby after the stopper has been inserted into the neck of container, the puncture area bulges slightly outward and remains in that position until the puncture needle of an infusion kit has been inserted into the stopper, and in that the puncture area bulges down into neck of the container when being pierced by the puncture needle and remains in this position as long as the puncture needle is inserted into the stopper, wherein the puncture area of the stopper is made of neodymium polyisoprene rubber.
