Patent ID: 7927270

Claim:
An external pressure sensing system, the system comprising: (a) a connecting member operable to connect to a syringe barrel, wherein the connecting member is further operable to connect to a needle, wherein the connecting member comprises a conduit permitting communication of fluid from the syringe barrel to the needle when the connecting member is connected to the syringe barrel and the needle, wherein at least a portion of the connecting member is positioned to maintain coaxial alignment in relation to the needle, wherein the at least a portion of the connecting member is positioned to maintain coaxial alignment in relation to the syringe barrel, wherein the connecting member is configured to maintain a distance between the syringe barrel and the needle such that the syringe barrel and the needle is configured for single-handed use; and (b) a pressure sensor in communication with the conduit, wherein the pressure sensor comprises an outer body, wherein the pressure sensor is configured to sense pressure of fluid within the connecting member, wherein the connecting member is configured to permit the pressure sensor to sense the pressure of the fluid while the fluid is communicated from the barrel to the needle, wherein the pressure sensor is configured to provide a visual indication of sensed pressure, wherein the visual indication of the sensed pressure is confined within a volume defined by the outer body of the pressure sensor.
