Infusion syringe with integrated pressure transducer

A syringe comprising:

• a barrel;
• a piston configured to slide within the barrel and to apply pressure to a fluid within the barrel, the piston comprising a pressure transducer at a distal end portion of the piston that is configured to generate an electronic signal proportional to the fluid pressure;
• a handle coupled to a proximal end portion of said piston, said handle comprising an infrared receiver, wherein the pressure transducer is communicatively coupled to said infrared receiver to transmit the electronic signal to said infrared receiver from an infrared transmitter that is electrically connected to said pressure transducer;
• a first piston advancement mechanism that is configured to provide to said piston a sliding motion that is induced by force at said handle;
• a second piston advancement mechanism that is configured to provide to said piston a sliding motion that is induced by a threaded mechanism to advance the piston without requiring rotation of the piston;
• and
• a switch for engaging either said first piston advancement mechanism or said second piston advancement mechanism.

A fluid pressure inducing syringe comprising:

• a barrel;
• a plunger comprising a pressure transducer at a distal end portion of the plunger, wherein the plunger is configured to slide within the barrel to apply pressure to a fluid within the barrel, wherein the pressure transducer is configured to generate a signal proportional to the fluid pressure;
• a handle coupled to a proximal end portion of the plunger, the handle comprising a signal receiver, wherein the pressure transducer is communicatively coupled to said signal receiver to transmit said signal to said signal receiver from a signal transmitter that is communicatively coupled to said pressure transducer, and wherein said signal from the pressure transducer is transmitted wirelessly from said signal transmitter to said signal receiver;
• a first plunger advancement mechanism that is configured to provide a sliding motion of the plunger that is induced by force at the handle;
• a second plunger advancement mechanism that is configured to provide a sliding motion of the plunger that is induced by a threaded mechanism to advance the plunger without requiring rotation of the plunger, wherein the threaded mechanism includes a sleeve having a threaded portion encompassing at least a portion of the plunger, the sleeve freely rotatable about the plunger;
• and
• a switch for engaging either the first plunger advancement mechanism or the second plunger advancement mechanism.
