Disposable assembly for drug infusion with pressure sensing for identification of and injection into fluid-filled anatomic spaces

A disposable fluid flow assembly for operation in connection with a fluid pump configured to provide a flow of fluid to the disposable fluid flow assembly, wherein the fluid pump comprises a central controller having a memory and the central controller is configured to control the flow of fluid in response to manual commands input via an input element, wherein the disposable fluid flow assembly comprises:

• an elongated flexible tube;
• a needle hub connected with the flexible tube, wherein the hub is configured for connecting a needle with the hub;
• a pressure sensor for sensing fluid pressure, wherein the pressure sensor is connected with the tube or the hub;
• a data line having a first end electrically connected with the pressure sensor and a second end having an electrical connector for connecting the data line with the fluid pump;
• an identification circuit embedded within or connected to the first electrical connector, wherein the identification circuit is configured to provide a plurality of signals to the central controller of the fluid pump when the disposable needle assembly is connected with the fluid pump, wherein the plurality of signals, including:
• a configuration signal indicative of the physical characteristics of the disposable needle assembly;
• a verification signal indicative of the disposable needle assembly being cooperable with the fluid pump;
• a first use signal identifying the particular disposable needle assembly so that the central controller can detect whether the specific disposable needle assembly was previously used.
