Problems solved by technology

like figure 1 As shown, the structure of the prior art hemostatic clip is to buckle the sides of the hemostatic clip by a whole buckle plane on the hemostatic clip. Since there are no limit positions on the left and right sides, the hemostatic clip is easy to be biased, and the tube body cannot be completely clamped. risk

Abstract

The invention relates to an extracorporeal circulation pipeline for venous hemodialysis. The extracorporeal circulation pipeline comprises a dialysis joint, a pressure sensor, a venous drip chamber, asecond haemostatic clip, a puncture needle pipeline connecting joint, a third hose, a fifth hose and a mother needle based branch pipeline, a liquid outlet of the dialysis joint is connected with a liquid inlet of the pressure sensor, a liquid outlet of the pressure sensor is connected with a liquid inlet of the venous drip chamber through the third hose, a liquid outlet of the venous drip chamber is connected with the puncture needle pipeline connecting joint through the fifth hose, a first branch pipe interface is formed in the upper end of the venous drip chamber, a liquid outlet end of the mother needle based branch pipeline is connected with the first branch pipe interface, and the second haemostatic clip is arranged on the fifth hose. The extracorporeal circulation pipeline for venous hemodialysis can detect the flow pressure of blood in a blood vessel, improve detection result precision and can prevent the risk of deviation of the haemostatic clip.

Description

technical field [0001] The invention relates to the structural field of extracorporeal circulation pipeline for hemodialysis, and specifically relates to an extracorporeal circulation pipeline for venous hemodialysis. Background technique [0002] The hemodialysis extracorporeal circulation circuit is a connecting circuit for human extracorporeal dialysis. Its main function is to connect the human body and the dialyzer, transport the blood in the human body to the dialyzer for purification, and guide it back to the human body to form a circulation. Its function is to replace blood vessels and act as a pipeline for blood flow. The hemodialysis extracorporeal circulation pipeline consists of two sets of pipelines, the arterial tube and the venous tube, which are respectively connected to the dialyzer and connected to the human artery and vein respectively. [0003] During the use of the hemodialysis extracorporeal circulation circuit, it is necessary to detect the pressure st...
