US 2026/0249016 A1 · DEVICES THAT FACILITATE INSERTION OF CENTRAL VENOUS CATHETERS

Abstract

A syringe includes a barrel, a plunger slidably mounted within the barrel chamber, and an elongate rod movably secured to the barrel. The rod is attached to the plunger and is configured to be engaged by a finger of a user holding the syringe for bidirectional movement of the plunger. A device includes a frame configured to be attached to a syringe barrel, and an elongate rod movably secured to the frame. The rod is configured to be engaged by a finger of a user holding the syringe for bidirectional movement of the plunger. A device includes an elongate rod having a proximal end configured to be secured to a thumb press of a plunger within a barrel of a syringe, and a distal end configured to be engaged by a finger of a user holding the syringe for bidirectional movement of the plunger within the barrel.

Dependent claims

A syringe, comprising:

a barrel defining a longitudinally extending chamber and comprising an open proximal end, and an open distal end;
a plunger slidably mounted within the chamber;
and
an elongate rod movably secured to an outer portion of the barrel, wherein the rod comprises a proximal end attached to the plunger, a distal end, and a finger platform adjacent the rod distal end that is configured to be engaged by a finger of a user holding the syringe, and wherein bidirectional movement of the rod via the finger platform causes corresponding bidirectional movement of the plunger within the barrel.
