PIERCING PROBES WITH OFFSET CONICAL PIERCING TIP AND FLUID-SAMPLING SYSTEMS COMPRISING THE PIERCING PROBES

摘要

Piercing probes for fluidic applications may include a body portion including a distal end of the piercing probe. The piercing probes may also include a piercing portion opposite the distal end of the piercing probe. The piercing portion may include a conical portion, which may include a piercing tip. The piercing probe may also include a continuous lumen defined through the body portion and the piercing portion. The continuous lumen may be centered about a primary longitudinal axis of the piercing probe. A longitudinal tip axis may be defined through the piercing tip parallel to the primary longitudinal axis. The longitudinal tip axis may be offset from the primary longitudinal axis by an offset distance greater than zero. Fluid-sampling systems including the piercing probes may further include a device configured to draw or expel fluid through the continuous lumen.

1. A piercing probe for fluidic applications, the piercing probe comprising:
a body portion including a distal end of the piercing probe, the body portion having a width that defines an outside diameter of the piercing probe; a piercing portion opposite the distal end of the piercing probe, the piercing portion comprising a conical portion having a piercing tip; and a continuous lumen defined through the body portion and the piercing portion from a distal opening at the distal end of the piercing probe to a proximal opening of the piercing probe in the piercing portion, the continuous lumen having a width that defines an inside diameter of the piercing probe,wherein:
the continuous lumen is centered about a primary longitudinal axis of the piercing probe; a longitudinal tip axis is defined through the piercing tip parallel to the primary longitudinal axis; and the longitudinal tip axis is offset from the primary longitudinal axis by an offset distance greater than zero.
