Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 As shown, one embodiment of the present application discloses an integrated external circulation pipeline, including a box body and an arterial pipeline area, a venous pipeline area and a plasma pipeline area arranged on the box body.

[0033] in:

[0034] The arterial pipeline area includes a blood collection input end 110, a blood collection pump input end 120, a blood collection output end 140 and a blood collection pump output end 130. The blood collection input end 110 is liquid-connected to the blood collection pump input end 120 through a first pipeline a, and the blood collection pump output end is liquid-connected to the blood collection output end 140 through a second pipeline b.

[0035] The venous line area includes a bubble trap 210, a return blood input 220, a reinfusion pump input 230, a reinfusion pump output 240, and a return blood output 250. The return blood input 220 and the bubble trap 210 are connected via a third line c, the bubble trap 210 and the reinfusion pump input 230 are connected via a fourth line d, and the reinfusion pump output 240 and the return blood output 250 are connected via a fifth line e. In actual use, a reinfusion pump 9 is connected between the reinfusion pump input 230 and the reinfusion pump output 240. The reinfusion pump 9 is used to provide power for the return blood, allowing the return blood to flow from the reinfusion pump input 230 through the reinfusion pump 9 into the fifth line e. The return blood output 250 is in fluid communication with the venous line 10 for reinfusion of blood into the human body.

[0036] The plasma pipeline area includes a plasma input end 310, a plasma pump input end 320, a plasma pump output end 330, a plasma output end 340 and a fresh plasma input end 381. The plasma input end 310 is liquid-connected to the plasma pump input end 320 through the sixth pipeline f, the plasma pump output end 330 is liquid-connected to the plasma output end 340 through the seventh pipeline g, and the fresh plasma input end 381 is liquid-connected to the bubble trap 210 through the eighth pipeline h.

[0037] The plasma output end 340 is used to be in liquid communication with the collection bag 8 through a pipeline, and the collection bag 8 is used to collect waste plasma.

[0038] In this embodiment, see Figure 1 and Figure 2 The integrated external circulation pipeline also includes a liquid pump input end 382 and a liquid pump output end 383. The fresh plasma input end 381 is used to be in liquid communication with the fresh plasma bag 12. The fresh plasma input end 381 is connected to the liquid pump input end 382 through a pipeline. A liquid pump 11 is connected between the liquid pump input end 382 and the liquid pump output end 383 to transport the fresh plasma to the bubble trap 210 through the eighth pipeline h.

[0039] Furthermore, the integrated external circulation pipeline also has a first interface 391 and a second interface 392, wherein the first interface 391 is connected to one end of the eighth pipeline h close to the bubble trap 210; the second interface 392 is liquid-connected to the bubble trap 210 through the fresh plasma pipeline i.

[0040] In the integrated external circulation circuit provided in the embodiment of the present application, the arterial circuit area, venous circuit area, and plasma circuit area are pre-installed on the box body, and some of the circuits are pre-connected. During use, the plasma separation and exchange device, blood sampling pump 2, and other equipment can be directly connected to the interfaces of the arterial circuit area, venous circuit area, and plasma circuit area in the integrated external circulation circuit, thereby reducing the workload of circuit connection. At the same time, since some of the circuits have been pre-connected, the circuit connection work can be simplified, thereby effectively reducing the probability of connection errors by the staff.

[0041] Furthermore, the plasma pipeline area includes a control valve group 370, which is used to control the opening and closing of the seventh pipeline g and / or the eighth pipeline h.

The first control valve 371 is used to control the on-off of the eighth pipeline h, and the second control valve 372 is used to control the on-off of the seventh pipeline g.

[0043] Furthermore, at least one of the first pipeline a, the second pipeline b, and the fifth pipeline e is equipped with a filter and a pressure detection device. This allows the filter to filter the fluid within the pipeline. The pressure detection device can monitor the fluid pressure within the corresponding pipeline, thereby improving the safety of blood exchange treatment.

[0044] In a possible implementation, the first pipeline a, the second pipeline b, and the fifth pipeline e are respectively provided with a filter and a pressure detection device.

[0045] In one possible embodiment, bubble trap 210 includes a first input end, a second input end, and a housing. The housing includes a top wall and sidewalls arranged at an angle relative to the top wall. The projections of the first and second input ends, perpendicular to the top wall, are located on the sidewalls. This allows liquid flowing out of the first and second input ends to land on the sidewalls. The sidewalls, inclined relative to the top wall, provide a buffering effect for the liquid, effectively reducing the generation of bubbles and cell damage caused by the high drop. Furthermore, the sidewalls provide a buffering effect for the liquid, thereby increasing the flow rate of the fluid and reducing the risk of clotting.

[0046] In a possible implementation, the bubble trap 210 is provided with an exhaust hole, and the integrated external circulation pipeline further includes an exhaust end 410 , and the exhaust hole is connected to the exhaust end 410 through the exhaust pipeline j.

[0047] In an application embodiment, the exhaust port 410 is in fluid communication with an exhaust bag through a pipeline, so that the gas in the bubble trap 210 can be collected in the exhaust bag.

[0048] See also Figure 1 and Figure 2 In one embodiment, the integrated external circulation pipeline also includes an anticoagulant pipeline area, which includes an anticoagulant input end 510, an anticoagulant pump input end 520 and an anticoagulant pump output end 530. The anticoagulant input end 510 is liquid-connected to the anticoagulant pump input end 520 through a first anticoagulant liquid pipeline, and the anticoagulant pump output end 530 is liquid-connected to the second pipeline b through a second anticoagulant liquid pipeline k.

[0049] The anticoagulation pump 15 is connected between the anticoagulation pump input end 520 and the anticoagulation pump output end 530 , and the anticoagulation pump is used to drive the anticoagulation liquid to flow from the second anticoagulation pipeline to the second pipeline b.

[0050] In one possible embodiment, the arterial, venous, and plasma lines are all detachably connected to the cartridge body via slots. This facilitates securing the lines to the cartridge body without requiring additional fixtures or clamping mechanisms, simplifying the structure of the integrated external circulation system.

[0051] On the other hand, an embodiment of the present application discloses a blood purification device, including the integrated external circulation pipeline as described above, which has all the technical effects of the aforementioned integrated external circulation pipeline and will not be repeated here.

[0052] In one possible implementation, see Figure 1 and Figure 2 As shown, the blood purification equipment also includes an arterial pipeline 1, a blood collection pump 2, a plasma separation device 3 and a plasma pump 7. One end of the arterial pipeline 1 is liquid-connected to the blood collection input end 110, the blood collection pump 2 is connected to the blood collection pump input end 120 and the blood collection pump output end 130, the plasma separation device 3 includes an input port 4, a first output port 5 and a second output port 6, the input port 4 is liquid-connected to the blood collection output end through a pipeline, the first output port 5 is connected to the return blood input end 220 through a pipeline, the second output port 6 is liquid-connected to the plasma input end 310 through a pipeline, and the plasma pump 7 is connected between the plasma pump input end 320 and the plasma pump output end 330.

[0053] In this embodiment, the plasma output end 340 is in fluid communication with the collection bag 8 via a pipeline for collecting waste plasma. The fresh plasma input end 381 is in fluid communication with the fresh plasma bag 12 so that the fresh plasma in the fresh plasma bag 12 flows into the bubble trap 210 through the pipeline and mixes with the blood cells.

[0054] The plasma separator 3 is used to separate blood into blood cells and plasma. The blood cells flow back to the bubble trap 210 through the first outlet 5, while the plasma flows out through the second outlet 6 and into the collection bag 8 through the plasma input end 310 and the plasma output end 340. Fresh plasma is then input into the bubble trap 210 through the fresh plasma input end 381, mixed with the blood cells, and then returned to the human body, completing the plasma exchange process.

[0055] In some embodiments of the present application, the plasma separation device 3 includes a centrifugal plasma separator.
