In the present embodiment, this blood back pipeline 9 to comprise after pump blood return tube 92 before blood return tube 90, filter jug 91 and pump, described filter jug 91 is provided with liquid inlet and liquid outlet, and the liquid inlet of described filter jug is communicated in described downtake pipe 8 by blood return tube 90 after described pump, the liquid outlet of described filter jug 91 is communicated in the other end of described pump prerolandic artery Rolando blood tube 1 by blood return tube 92 before described pump; Another on described filter jug 91, be also connected with one in order to the second exhaust pipe 93 of aerofluxus.
In the present embodiment, be also provided with the 3rd arterial side arm 10, before described pump, blood return tube 92 is communicated in the other end of described pump prerolandic artery Rolando blood tube 1 by described 3rd arterial side arm 10; Preferably, described 3rd arterial side arm 10 is connected with described pump prerolandic artery Rolando blood tube 1 one.
In the present embodiment, described second exhaust pipe 93 is provided with the first control folder 11 in order to be opened by described second exhaust pipe or to close, namely described first control folder 11 can be closed or discharge gas;
Separately blood return tube 90, described 3rd arterial side arm 10 and described pump prerolandic artery Rolando blood tube 1 are respectively respectively arranged with to control second of fluid flow after described downtake pipe 8, described pump and control folder 12.
In the present embodiment, on described second exhaust pipe 93 and the position being close to described filter jug 91 is provided with described first controls folder;
Another on described downtake pipe 8 and after being close to the position of described tremulous pulse kettle 6, described pump, blood return tube 90 be close on the position of described filter jug 91, described 3rd arterial side arm 10 and be close in the position of described pump prerolandic artery Rolando blood tube 1 and described pump prerolandic artery Rolando blood tube 1 and the position being close to described blood pump 3 inlet is respectively respectively arranged with described second controls folder.
In the present embodiment, between the other end and the inlet of described blood pump 3 of described pump prerolandic artery Rolando blood tube 1, one is also connected with in order to be connected the first arterial side arm 2 of normal saline; Separately between described first pump artery blood tube 5 and the liquid outlet of described blood pump 3, be also connected with one in order to be connected the second arterial side arm 4 of heparin.
In the present embodiment, the on described first arterial side arm 2 and described second arterial side arm 4, be also provided with to control fluid flow respectively the 3rd controls folder 13.Preferably, to be close on the position of described blood pump 3 inlet and described second arterial side arm 4 and the position being close to described blood pump 3 liquid outlet is provided with the 3rd controls folder 13 on described first arterial side arm 2 respectively.
The new operation principle of this practicality is: after whole hemodialysis pipeline (containing arterial line and venous line) closed is made in advance, blood return tube before pump 92 is connected with the 3rd arterial side arm 10 and opens second on the 3rd arterial side arm 10 and control to press from both sides, then again blood return tube after pump 90 is connected with downtake pipe 8 and presss from both sides and close second on downtake pipe 8 and control to press from both sides, be exhausted by second exhaust pipe 93; After second exhaust pipe 93 aerofluxus, folder closes first on it and controls folder, and what folder closed after described pump in blood return tube 90 and the 3rd arterial side arm 10 simultaneously second controls folder.
When carrying out lower machine blood back, operating procedure is: 1. slow down blood flow, 3rd control of opening on described first arterial side arm 2 is pressed from both sides and second after described pump on blood return tube 90, downtake pipe 8 and the 3rd arterial side arm 10 controls folder, and the second control that folder closes in described pump prerolandic artery Rolando blood tube 1 is simultaneously pressed from both sides; 2. by described first arterial side arm 2 to saline injection in blood pump 3, blood pump 3 drives normal saline to flow to described tremulous pulse Hu6Chu from the first pump artery blood tube 5, also means the blood recovery in the first pump artery blood tube 5 to tremulous pulse Hu6Chu simultaneously; 3. because this utility model is provided with a blood back pipeline between the downtake pipe 8 and pump prerolandic artery Rolando blood tube 1 of tremulous pulse kettle, therefore two blood back paths are then formed with in tremulous pulse kettle position, wherein the normal saline of a part drives and makes blood recovery in tremulous pulse kettle 6, second pump artery blood tube 7 and hemodialyzer in patient body, forms first blood back path; Flow in described pump prerolandic artery Rolando blood tube 1 after blood return tube 92 and the 3rd arterial side arm 10 before blood return tube 90, filter jug 91, pump after the normal saline of another part then flows through downtake pipe 8, pump successively, make blood recovery in pump prerolandic artery Rolando blood tube 1 in patient body, form second blood back path.
This operation achieves artery and vein closed blood back simultaneously, and whole blood back process does not need termination of pumping.
