Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Fig. 1, shown in Fig. 2 and Fig. 3, the haemodialysis equipment of a kind of adjustable calcium ion concentration of the present invention, comprise cabinet 1 and main circuit board 2, patient 29 is connected to the first blood pump 4 and the second blood pump 5 by transducer potector 3 points of two-way, described first blood pump 4 is connected with dialyser 6 and concentration adjustment pump 7, described dialyser 5 is provided with flow prover 8, described flow prover 8 is provided with peristaltic pump 9, described concentration adjustment pump 8 is connected on main circuit board 2 by motor 10, clamp 11 is provided with between described second blood pump 5 and patient 29, sensor 12 is provided with between described clamp 11 and the second blood pump 5, described sensor 12 is connected with main circuit board 2, described main circuit board 2 is connected with control panel 13, described control panel 13 is fixed on cabinet 1, described main circuit board 2 is connected with electric heater 14, described electric heater 14 ground connection, described main circuit board 2 incoming transport 220V power supply 15, described alternating current 220V power supply 15 is connected with electric heater 14 by electric fuse 16.
On above-described embodiment preferably, described flow prover 8 comprises fluid reservoir 17, pipeline 18, flow transducer 19, hemodialysis device detector 20, timing controller 21, two-position three way magnetic valve 22, container 23 and electronic scale 24, described fluid reservoir 17 connects peristaltic pump 9 successively by pipeline 18, flow transducer 19, two-position three way magnetic valve 22 and container 23, described flow transducer 19 connects hemodialysis device detector 20 by cable 30, described two-position three way magnetic valve 22 connects timing controller 21, and be connected to fluid reservoir 17 and container 23 respectively by pipeline 18, described container 23 is placed on electronic scale 24.
