Problems solved by technology

[0003] 1) Hemofiltration treatment can only be performed in a single dilution method, and the relative removal effect of middle molecular toxins is relatively poor
[0004] 2) Only simple hemofiltration or hemodialysis treatment can be performed, and medium and small molecule toxins cannot be removed at the same time
[0005] 3) An external reverse osmosis water treatment device is required, and the one-time investment of the whole machine is large, and it is not convenient for bedside mobile treatment in the emergency department

Embodiment 1

[0029] Such as figure 1 As shown, a display interface 1 is installed on the upper end of the cabinet 10. Four peristaltic pumps are installed on the upper part of the cabinet 10. These four peristaltic pumps are distributed in a rectangle. The upper left one is the first peristaltic pump 2, and the lower left one is the fourth peristaltic pump Of the pumps 3, the one on the upper right is the third peristaltic pump 12, and the one on the lower right is the second peristaltic pump 13. A hemodialyzer 11 is installed in the middle of the housing 10 , and the right side of the hemodialyzer 11 is equipped with a bubble detector 16 and a blocking clamp 18 , and the bubble detector 16 is located above the blocking clamp 18 . Below the hemodialyzer 11, a first electronic scale 19 and a second electronic scale 8 are arranged side by side, the first electronic scale 19 is located on the right side of the second electronic scale 8, and a fluid replacement bag 20 is suspended on the first...

Embodiment 2

[0032] Such as figure 2 As shown, the fluid replacement circuit in this embodiment is as follows: one end of the fluid replacement pipeline 15 is connected to the fluid replacement bag 20, and the other end of the fluid replacement pipeline 15 passes through the heater 17 and is divided into two circuits, one of which bypasses the third peristaltic pump 12 Afterwards, it is connected with the venous line 7, and the other path bypasses the second peristaltic pump 13 and is connected with the outer membrane joint at the lower end of the hemodialyzer 11. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0034] Such as image 3 As shown, the fluid replacement circuit in this embodiment is as follows: one end of the fluid replacement pipeline 15 is connected to the fluid replacement bag 20, and the other end of the fluid replacement pipeline 15 bypasses the second peristaltic pump 13 and then passes through the heater 17 and then divides into two circuits. One path is connected to the venous line 7, and the other path is connected to the outer membrane joint at the lower end of the hemodialyzer 11 after bypassing the rear 12 of the third peristaltic pump. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a bedside continuous hemodialysis filtration device. After bypassing a first peristaltic pump (2), an artery pipeline (6) is connected with an intramembrane connector of a hemodialyzer (11), and the other intramembrane connector of the hemodialyzer (11) is connected with a vein pipeline (7); a waste liquor pipeline (4) is connected with an out-membrane connector at the upper end of the hemodialyzer (11) and is connected with a waste liquor bag (9) after bypassing a fourth peristaltic pump (3); and a liquor compensation pipeline (15) is connected with a liquor compensation bag (20) and is divided into two paths, wherein one path of the liquor compensation pipeline (15) is connected with the vein pipeline (7), and the other path of the liquor compensation pipeline (15) is connected with the artery pipeline (6) or an out-membrane connector at the lower end of the hemodialyzer (11). The bedside continuous hemodialysis filtration device does not need an external water processing device, can be used for realizing bedside movement and rapid rescue treatment in an emergency department, and is capable of simultaneously performing front and rear dilution treatment as well as hemodialysis and filtration treatment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bedside continuous hemodiafiltration device. Background technique [0002] Blood purification therapy is a common treatment method for acute and chronic renal failure, multiple organ failure, sepsis, etc. The existing blood purification devices have the following deficiencies: [0003] 1) Hemofiltration treatment can only be performed in a single dilution method, and the relative removal effect of middle molecular toxins is relatively poor. [0004] 2) Only simple hemofiltration or hemodialysis treatment can be performed, and medium and small molecule toxins cannot be removed at the same time. [0005] 3) An external reverse osmosis water treatment device is required, and the one-time investment of the whole machine is large, and it is not convenient for bedside mobile treatment in the emergency department. Contents of the invention [0006] The technica...
