Description

Hemodialysis is with two side screw thread mouths side branch venous pot connecting pipe

Technical Field

The utility model relates to the technical field of medical equipment, specifically a hemodialysis is with two side screw thread mouths collateral branch vein kettle connecting pipe.

Background

Under normal conditions, blood is led out through an arterial pipeline under the drive of a blood pump, passes through a dialyzer and then is returned to the body through a venous pipeline with a venous pot.

When the heparin-free dialysis or citric acid anticoagulation dialysis treatment is carried out, the venous pot is easy to coagulate blood, and blood cannot be returned after the venous pot coagulates blood, so that the extracorporeal circulation blood cannot be returned directly, and blood loss is caused. The method for replacing the pipeline during blood coagulation is complex in operation, long in time consumption, easy to cause blood loss, and has the risk of infection due to splashing of blood drops when the pipeline is disconnected. There is currently no better solution to coagulation other than the prevention of coagulation in the clinic.
