Description

A hemodialysis side connection pipeline

technical field

The utility model relates to a medical device, in particular to a hemodialysis side connection pipeline.

Background technique

Hemodialysis is a regular treatment for patients with uremia and certain diseases. It has high requirements on hygienic conditions. The dialysis circuit needs to be pre-washed with normal saline. The current pre-flushing of the hemodialysis pipeline is to connect an infusion bypass on the branch of the pump front pipe joint of the dialysis pipeline, and the infusion bypass is connected to normal saline. The dialyzer must be replaced immediately to continue dialysis. When the original infusion bypass cannot be opened or used at the same time, a bag of normal saline solution must be re-opened to connect the infusion set, which greatly prolongs the disposal time and affects blood coagulation. Moreover, when the fistula puncture needle is used, the existing dialysis line cannot be pre-washed, and a syringe must be used to pump out physiological saline to exhaust the air and flush the disinfectant in the fistula puncture needle, which increases the workload and contaminated links.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the hemodialysis side connection pipeline of the utility model includes a dialysis blood circuit and an infusion bypass, and the dialysis blood circuit is sequentially connected to the arterial end 1 of the dialyzer, the arterial pot 2, the rear end 4 of the blood pump, and the blood pump. The front end 5, the arterial end blood collection part 7, the clamp 8, the arterial blood introduction part 9, the port protection cap 10, the infusion bypass 11 is connected with the front tube clamp 6, the joint 11-4, the flow regulator 11-3, the drip Bucket 11-2, physiological saline bag 11-1, the infusion bypass 11 is connected with the dialysis blood circuit at the front end 5 of the blood pump part, the infusion bypass 11 is connected with a side branch 11-5, and the side branch 11-5 includes The branch flow regulator 11-6, the branch connector 11-7, and the side branch 11-5 are connected with the infusion bypass 11 before the flow regulator 11-3. Arterial blood drainage place 9 is connected with arterial puncture needle during treatment.

Further, a heparin tube 3 is connected to the rear end 4 of the blood pump part of the dialysis blood circuit, and the heparin tube 3 is connected to the dialysis blood circuit through a three-way tube.

Further, the branch joint 11-7 is connected with the internal fistula puncture needle.
