Embodiment 1

[0012] see figure 1 , a type A hemodialysis preflush waste liquid discharge tube, which is composed of a cover 1, a port 2 connected to the preflush of the blood line tube, a connecting hose 3, a clip 4, and a connecting tube 5. One end of the connecting hose 3 is connected to the blood line tube The port 2 of the preflush connection, the other end of the connecting hose 3 is connected to the connecting pipe 5, the port 2 is threaded and fits the cover 1, and the clamp 4 is arranged on the connecting hose 3 for clamping the connecting hose 3. The diameter of the connecting pipe 5 is greater than the diameter of the waste liquid discharge pipe attached to the hemodialysis machine.

[0013] Before the start of hemodialysis treatment, the nurse must pre-flush the hemodialysis circuit and dialyzer, and then connect the vascular access to establish blood circulation before hemodialysis can be performed. When preflushing the hemodialysis pipeline and the dialyzer, the original wast...

Embodiment 2

[0015] see figure 2 , a B-type hemodialysis preflush waste liquid discharge tube, consisting of a connection port cover 6, a threaded connection port 7, a waste liquid discharge connection pipe 8, a waste liquid discharge connection pipe clip 9, a fastening ring 10, and a tee joint Port 11, three-way joint 12, waste liquid discharge connecting pipe clip 9 is set on the waste liquid discharge connecting pipe 8, and the waste liquid discharge connecting pipe 8 is connected to the vertical port 11 of the three-way joint through the fastening ring 10, and the three-way joint 12 The diameters of the left and right ports are smaller than the diameters of the waste liquid discharge pipes of the hemodialysis machine.

[0016] Before the start of hemodialysis treatment, the nurse must pre-flush the hemodialysis circuit and dialyzer, and then connect the vascular access to establish blood circulation before hemodialysis can be performed. When pre-washing the hemodialysis pipeline and ...

Abstract

The invention provides a hematodialysis pre-flushing waste liquid drainage tube. The hematodialysis pre-flushing waste liquid drainage tube comprises a type A and a type B. The type A is composed of a cover, a port connected with a blood path tube in a pre-flushing mode, a connecting hose, a clamp and a connecting tube. The type B is composed of a connecting port cover, a connecting port with a thread, a waste liquid drainage connecting tube, a waste liquid drainage connecting tube clamp, a fastening ring, a tee joint vertical port and a tee joint. The idea of totally-closed pre-flushing of a disposable hematodialysis pipeline can be achieved, pre-flushing waste liquid can be directly drained into a waste liquid tube of a dialysis machine during pre-flushing of the disposable hematodialysis pipeline, working processes are simplified, the workload is relieved, and pre-flushing of the blood path tube is easier, more convenient and safer. The hematodialysis pre-flushing waste liquid drainage tube is reasonable in design, lower in use cost and more environmentally friendly, and environmental pollution is relieved.

Description

technical field [0001] The invention belongs to accessories of medical instruments, and relates to a waste liquid discharge pipe, in particular to a hemodialysis waste liquid discharge pipe. Background technique [0002] Hemodialysis is one of the main renal replacement therapy methods for patients with renal failure. During hemodialysis, the doctor first establishes the patient's vascular access, and then connects the pre-flushed dialyzer and the disposable blood line to the patient's vascular access , Establish extracorporeal circulation and start hemodialysis treatment. Although the current hemodialysis blood line tube with the waste liquid bag realizes the concept of fully-closed preflushing of the disposable hemodialysis line, it also has the following defects: 1. When using the existing disposable hemodialysis line for preflushing, The pre-flushing waste liquid needs to be discharged into the waste liquid bag, and the waste liquid bag needs to be collected after the m...
