More Information
Summary:A syringe with adjustable penetration depth, comprising a tubular syringe barrel, a plunger positioned within the syringe barrel, a hub bearing a needle and attached to the syringe barrel, a movable collar having an open proximal end received over the hub, a distal end wall having an opening through which the needle protrudes, and a sidewall extending proximally from the distal end wall, the sidewall having an interior surface engaging the hub or syringe barrel, and a retaining feature on the collar engaging the hub or barrel and retaining the collar at a plurality of axial positions. The collar travels with respect to the hub along a path defined by the retaining feature on the interior surface of the sidewall engaging the hub or barrel, exposing a greater length of the needle as the collar travels toward the plunger.
