Abstract

A system for delivering or withdrawing a fluid to or from the body of a patient in a manner that permits delivery to be controlled based upon feedback from the patient, the system including a syringe assembly providing a syringe operably coupled to one or more sensors adapted to determine one or more corresponding parameters associated with fluid delivery and/or withdrawal, and a monitor adapted to be communicably associated with the one or more sensors of the syringe assembly, and optionally with other sensors or inputs providing additional parameters as well, the monitor comprising one or more read out mechanisms either directly or indirectly corresponding to the one or more fluid delivery/withdrawal parameters, and optionally with one or more of the additional parameters as well.

Claims

1. A system for delivering or withdrawing a fluid to or from the body of a patient in a manner that permits delivery to be controlled based upon feedback from the patient, the system comprising:

a) a syringe assembly comprising a syringe adapted to contain, and to deliver and/or withdraw, a fluid to and/or from the body, the syringe being operably coupled to one or more sensors adapted to determine one or more corresponding parameters associated with fluid delivery and/or withdrawal, and b) a monitor adapted to be communicably associated with the one or more sensors of the syringe assembly, the monitor comprising one or more read out mechanisms either directly or indirectly corresponding to the one or more fluid delivery/withdrawal parameters.

2. A system according to claim 1, wherein at least one sensor and corresponding parameter associated with the syringe is selected from the group consisting of:

rate of fluid delivery or withdrawal, amount of fluid delivered or withdrawn at any point in time and/or in total, amount of drug or material delivered or withdrawn at any point in time and/or in total, concentration of drug or material being delivered, pressure of fluid delivery or withdrawal, velocity of the fluid delivered or withdrawn, time associated with fluid delivery or withdrawal, size of the syringe being used, and amount of fluid in the syringe being used.

3. A system according to claim 1, wherein the system comprises one or more additional sensors or inputs, not operably coupled to the syringe assembly but providing corresponding additional parameters that are communicably associated with the monitor.

4. A system according to claim 3, wherein the additional parameters comprise biological data selected from the group consisting of temperature, oxygen saturation, respiratory rate, blood pressure, pressure at the site of infusion, and heart rate.

5. A system according to claim 1, wherein the monitor provides one or more features selected from the group consisting of memory/recall function, printout capability, calibration means, fail safe mechanisms, patient thermal indicator, reset button, and a power indicator.
