摘要：
The invention provides improved apparatuses and related methods for the detection of needle penetration into negative pressure corporal spaces such as the epidural space. In one aspect, the invention provides a needle hub that includes a fluid reservoir chamber and a plunger engaged therewith, so that insertion of the plunger into the chamber displaces fluid causing a hanging drop to form.
