Abstract:
1. A pressure applying and monitoring syringe, comprising: a barrel; a plunger configured to slide within the barrel and to apply pressure to a fluid within the barrel, said plunger comprising a pressure transducer at a distal end portion of said plunger that is configured to generate a signal proportional to the fluid pressure; a handle coupled to a proximal end portion of said plunger, said handle comprising an infrared receiver coupled to a display, wherein the pressure transducer is communicatively coupled to said infrared receiver, and wherein all of said handle is prevented from entering into said barrel; a first plunger advancement mechanism that is configured to provide to said plunger a sliding motion that is induced by thumb force at said handle; a second plunger advancement mechanism that is configured to provide to said plunger a sliding motion that is induced by a threaded mechanism to advance the plunger without requiring rotation of the plunger; and a switch for engaging either said first plunger advancement mechanism or said second plunger advancement mechanism.
