The application discloses a full-automatic processing production line for a venous needle, which comprises a hose conveying mechanism, a first glue applying mechanism, a second glue applying mechanism, a needle head butt joint mechanism, a butt joint head butt joint mechanism and a cap mechanism, wherein the hose conveying mechanism is sequentially connected with the first glue applying mechanism, the needle head butt joint mechanism, the second glue applying mechanism, the butt joint head butt joint mechanism and the cap mechanism, and the above mechanisms are all installed on a table top; automatic assembly of the venous needle is realized, a cover is sleeved on the butt joint head of the venous needle, and meanwhile, the processing efficiency of the venous needle is improved.

In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.
