Patent ID: 8888677

Claim:
An apparatus comprising: (a) a pressure monitoring device, wherein the pressure monitoring device is configured to be in communication with a syringe, wherein the pressure monitoring device is configured to have a predetermined threshold pressure; (b) an actuation portion, wherein the actuation portion comprises a first elongate member and a second elongate member coupled at a pivot joint, wherein the first elongate member comprises a plunger holder secured to a plunger of the syringe, wherein the second elongate member comprises a syringe holder secured to a barrel of the syringe, and wherein the actuation portion is operable to draw the plunger of the syringe from the barrel of the syringe; (c) a visual indicator, wherein the visual indicator is in communication with the pressure monitoring device, wherein the visual indicator is associated with the predetermined threshold pressure; and (d) a stopping mechanism in communication with the actuation portion, wherein the stopping mechanism forms the pivot joint of the actuation portion, and wherein the stopping mechanism is configured to prevent further actuation of the actuation portion in response to a sensed pressure exceeding or falling below the predetermined threshold pressure.
