Abstract
A hypodermic needle structure for making shallow injections of local anesthetic into human tissue under relatively high pressure in which an elastomeric sheath on the needle shank bears against the punctured tissue immediately surrounding the needle shank to form a pressure seal against leakage of the anesthetic liquid and of the puncture hole to facilitate the maintenance of relatively high liquid pressures at the lumen of the needle while the liquid works its way through connected tissue to the targeted nerve site.
