    • A device may include a first locking mechanism configured to connect a first end of the device to a needle, a second locking mechanism configured to connect a second end of the device to a syringe, a pressure transducer, a microprocessor and a light emitting diode. The pressure transducer may be configured to measure a first pressure at a first time and a second pressure at a second time. The microprocessor may be configured to receive the first pressure and the second pressure from the pressure transducer, determine a pressure difference between the first pressure and the second pressure, and determine a time difference between the first time and the second time. The light emitting diode may be configured to signal when the needle is properly situated based on the pressure difference and the time difference.
    • 装置可以包括被配置为将装置的第一端连接到针的第一锁定机构,配置成将装置的第二端连接到注射器的第二锁定机构,压力传感器,微处理器和发光二极管。 压力传感器可以被配置成在第一时间测量第一压力,并在第二时间测量第二压力。 微处理器可以被配置为从压力传感器接收第一压力和第二压力,确定第一压力和第二压力之间的压力差,并且确定第一时间和第二时间之间的时间差。 发光二极管可以被配置为基于压差和时间差来指示针是否正确定位。
