The utility model discloses an adopt following technical scheme to realize:
the utility model provides an extracorporeal circulation blood path of a blood purification device, which comprises an artery pipeline and a vein pipeline, wherein the artery pipeline comprises an artery pipeline starting end, an artery injection tee joint, an artery pressure sensor protector, a pump pipe, a heparin pipe and an artery dialysis joint which are sequentially arranged on an artery main pipe along the liquid flow direction, and the artery pressure sensor protector and the heparin pipe are respectively connected with the head end and the tail end of the pump pipe; the vein pipeline comprises a vein dialysis connector, a vein medicine injection tee joint, a vein pot and a vein pipeline termination end which are sequentially arranged on the vein main pipe along the liquid flow direction, and the vein pot is also provided with a vein pressure sensor protector, a vein first branch pipe and a vein second branch pipe; each pipe is provided with a flow stopping clip.
Furthermore, still be provided with the first branch pipe of artery and artery second branch pipe on the arterial line, the first branch pipe of artery sets up between artery injection tee bend and arterial pressure sensor protector, and the artery second branch pipe sets up between heparin tube and arterial dialysis connect.
Furthermore, a communicating joint is arranged on the starting end of the arterial pipeline.
Further, the inner diameter of the pump pipe is 6.0-6.3 mm.
The utility model has the advantages that: the arterial pipeline does not contain an arterial pot, and the diameter of the pump pipe is smaller. The artery pipeline reduces the retention time of blood in the pipeline, reduces the blood coagulation condition, avoids the formation of blood foam, and reduces the dialysis risk of patients. Meanwhile, an artery second branch pipe is reserved between the pump pipe and the dialysis connector, so that the pump pipe and the dialysis connector can be conveniently connected with the fluid infusion pipe to be diluted before dialysis, and can also be connected with physiological saline after dialysis so as to flush blood in the pipeline back into the body of a patient, thereby avoiding blood loss of the patient. The venous pot is provided with two branch pipes, when one branch pipe is connected with the fluid infusion pipe during dilution after hemodialysis filtration, the rest branch pipe can be used for injecting medicine or used for other purposes according to conditions. The condition that the branch pipe is occupied by the fluid infusion pipe and the medicine injection or other operations can not be carried out when the common dialysis pipeline is diluted after hemodialysis filtration is carried out is avoided.
