A WORD ABOUT LATEX RUBBER
NASOPHARYNGEAL AIRWAYS

Sun•Med is please to announce our original “Blue” latex nasopharyngeal tubes have been improved through a unique manufacturing process. All nine sizes are treated to provide an extremely smooth surface to accommodate the patient’s comfort and easing of insertion and removal. To reduce undesirable proteins, a proprietary three-step procedure is employed prior to sterilizing this product, which removes antigenic protein inherent to all natural latex.

TEST I: ASTM D 5712 TOTAL PROTEIN (LOWRY)
A total protein Lowry Assay test has been
obtained on our nasopharyngeal tubes indicating
less than 50ug/g total protein.

TEST II: ASTM D 64499-00 ANTIGENIC PROTEIN
The newer, more specific Elisa test to determine
the antigenic protein level has determined
our nasopharyngeal tubes have less
than 0.6ug/g antigenic protein.
The above analyses were carried out by
Guthrie Research Institute and certified to
Sun•Med by Akron Rubber Laboratory Inc.,
both the Lowry Assay and the Elisa test
results are available upon request.
