(1) Note. Obviously the needle holding hub of a hypodermic syringe limits the depth of penetration of the needle into the body. However, to be classified as an original in this subclass, a patent must include in its claimed subject matter a recitation of structure specifically designed to control the depth of insertion of a piercing member into the body and not intended primarily for some other purpose, such as, for example, holding a needle.

Having means for varying, regulating, indicating, or limiting injection pressure or aspirating suction:
This subclass is indented under subclass 93.01. Subject matter including apparatus for changing, controlling, signifying, or restricting the magnitude of the pressure or vacuum under which a body treating material is injected into or removed from the body.

Means varying or regulating suction:
This subclass is indented under subclass 118. Subject matter including means for changing, altering, or controlling the
