Description

Technical Field

[0001] The utility model relates to the technical field of blood purification, in particular to a nano dialysis membrane layer with good dialysis effect. Background Technique

[0002] The hemodialyzer is used in cooperation with a dialysis machine and pipelines for hemodialysis of patients with acute and chronic renal failure. The hemodialyzer mainly consists of a shell and a polymer dialysis membrane installed inside the shell. When blood flows into the shell from the liquid inlet of the shell, the blood then enters the dialysis membrane. Molecules smaller than the pore diameter of the micropores on the membrane wall are separated from the micropores on the membrane wall to the outside of the membrane according to the principle of diffusion and are carried away by the dialysis fluid flowing in the opposite direction outside the membrane.

[0003] Existing nano dialysis membranes are usually bundled together directly and vertically placed into the hemodialyzer, and then the dialysis fluid gradually flows through each group of nano dialysis membranes from bottom to top. During the process of the dialysis fluid flowing from the bottom to the top of the hemodialyzer, there are often a large number of metabolites and toxic substances in the dialysis fluid at the top of the hemodialyzer, thereby reducing the purification effect of the top part of the nano dialysis membrane on the blood. At the same time, since the nano dialysis membranes are often used in bundles of thousands or tens of thousands, the gap between adjacent nano dialysis membranes is very narrow, which cannot fully ensure that the dialysis fluid can flow stably outside each group of nano dialysis membranes, and may thus lead to some nano dialysis membranes not achieving the predetermined dialysis effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a nano dialysis membrane layer with good dialysis effect to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A nano dialysis membrane layer with good dialysis effect, including a main cylinder as an installation carrier. Inside the main cylinder, twelve partition cabins are sequentially arranged from top to bottom, and ten arc-shaped partition bins are symmetrically arranged inside each partition cabin. A number of nano dialysis membrane tubes are evenly arranged inside the main cylinder. A number of the nano dialysis membrane tubes penetrate through the twelve partition cabins, and a number of the nano dialysis membrane tubes are respectively located inside the ten arc-shaped partition bins. An infusion chamber and a drainage chamber are symmetrically installed at the center inside the main cylinder. Drainage through holes communicating with the inside of each arc-shaped partition bin are evenly opened on the outer sides of the infusion chamber, and liquid inlet through holes communicating with the inside of each arc-shaped partition bin are evenly opened on the outer sides of the drainage chamber. Collection bins are symmetrically installed at both ends of the main cylinder.

[0006] Preferably, one end of the infusion chamber and the drainage chamber away from each other extends out of the outer side of the collection bin and is installed with a connecting pipe.

[0007] Preferably, a circular chamber is provided at the central position of the partition chamber, and the circular chamber is communicated with the inside of the liquid discharge chamber through a liquid inlet through hole, and the circular chamber is communicated with the inside of the liquid infusion chamber through a liquid discharge through hole.

[0008] Preferably, the ten pairs of arc-shaped partition chambers inside the partition chamber together form ten groups of concentric circles, and the radii of the ten groups of concentric circles gradually increase from the central position of the main cylinder to the edge position.

[0009] Preferably, the liquid discharge chamber is communicated with the top end inside the arc-shaped partition chamber through a liquid inlet through hole, and the liquid infusion chamber is communicated with the bottom end inside the arc-shaped partition chamber through a liquid discharge through hole.

[0010] Preferably, a connecting pipe is installed at the central position of the end of the collecting chamber away from the main cylinder, and a connector is installed at the end of the connecting pipe away from the collecting chamber.

[0011] Preferably, the nano-dialysis membrane tube has a hydroxyl-active surface, and the average pore diameter of the holes on the surface of the nano-dialysis membrane tube is 0.1 - 1 nm.

[0012] Beneficial Effects

[0013] Compared with the prior art, the present utility model provides a nano-dialysis membrane layer with good dialysis effect, and has the following beneficial effects:

[0014] 1. The present utility model arranges multiple partition chambers inside the main cylinder, thereby dividing the outside of all the nano-dialysis membrane tubes inside the main cylinder into multiple segments. Then, the dialysis fluid is orderly transported into the inside of each group of partition chambers by the liquid infusion chamber in cooperation with the liquid inlet through holes, so that each segment outside the nano-dialysis membrane tube can contact with fresh dialysis fluid, which helps to make the dialysis effect of the whole nano-dialysis membrane tube better.

[0015] 2. The present utility model arranges ten pairs of arc-shaped partition chambers inside each group of partition chambers, frames several groups of nano-dialysis membrane tubes inside the main cylinder in these twenty groups of arc-shaped partition chambers respectively, and then sends the dialysis fluid into each group of arc-shaped partition chambers by the liquid infusion chamber in cooperation with the liquid discharge through holes. Thus, the nano-dialysis membrane tubes inside each group of arc-shaped partition chambers can stably contact with the dialysis fluid, further improving the stability of the contact between the dialysis fluid and the nano-dialysis membrane tubes, and thus fully ensuring the blood purification effect of each group of nano-dialysis membrane tubes in cooperation with the dialysis fluid.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] As Figures 1-5 shown, a nano dialysis membrane layer with good dialysis effect includes a main cylinder body 10 as an installation carrier. Inside the main cylinder body 10, twelve partition cabins 11 are sequentially arranged from top to bottom, and inside each partition cabin 11, ten arc-shaped storage bins 12 are symmetrically arranged. Inside the main cylinder body 10, a number of nano dialysis membrane tubes 13 are evenly arranged. A number of nano dialysis membrane tubes 13 all penetrate through the twelve partition cabins 11, and a number of nano dialysis membrane tubes 13 are respectively located inside the ten arc-shaped storage bins 12. Inside the main cylinder body 10, an infusion bin 14 and a drainage bin 15 are symmetrically installed at the center. On the outer sides of the infusion bin 14, liquid drainage through holes 17 communicating with the inside of each arc-shaped storage bin 12 are evenly opened. On the outer sides of the drainage bin 15, liquid inlet through holes 16 communicating with the inside of each arc-shaped storage bin 12 are evenly opened. Collection bins 20 are symmetrically installed at both ends of the main cylinder body 10.

[0026] In this embodiment, at the ends of the infusion bin 14 and the drainage bin 15 that are far away from each other, connector tubes 18 are installed outside the collection bin 20, which helps the dialysis fluid to enter the infusion bin 14 and then be discharged from the drainage bin 15.

[0027] In this embodiment, a circular chamber is provided at the central position of the separation compartment 11, and the circular chamber is internally communicated with the drainage chamber 15 through the liquid inlet through-hole 16, and the circular chamber is internally communicated with the infusion chamber 14 through the liquid drainage through-hole 17, which helps to make full use of the space inside the main cylinder 10 and place more groups of nano dialysis membrane tubes 13.

[0028] In this embodiment, ten pairs of arc-shaped compartments 12 inside the separation compartment 11 together form ten groups of concentric circles, and the radii of the ten groups of concentric circles gradually increase from the central position of the main cylinder 10 to the edge position, which helps to orderly divide several groups of nano dialysis membrane tubes 13 into twenty parts, and then enables the dialysis fluid to better contact each group of nano dialysis membrane tubes 13.

[0029] In this embodiment, the drainage chamber 15 is communicated with the top end inside the arc-shaped compartment 12 through the liquid inlet through-hole 16, and the infusion chamber 14 is communicated with the bottom end inside the arc-shaped compartment 12 through the liquid drainage through-hole 17. The difference in the relative height between the liquid inlet through-hole 16 and the liquid drainage through-hole 17 helps the dialysis fluid to better flow through each group of nano dialysis membrane tubes 13.

[0030] In this embodiment, a connecting pipe 21 is installed at the central position of one end of the collection chamber 20 away from the main cylinder 10, and a connector is installed at one end of the connecting pipe 21 away from the collection chamber 20, which helps to make the blood enter the collection chamber 20 orderly or be discharged from the collection chamber 20.

[0031] In this embodiment, the nano dialysis membrane tube 13 has a hydroxyl active surface, and the average pore diameter of the holes on the surface of the nano dialysis membrane tube 13 is 0.1 - 1 nm, which helps to improve the dialysis effect of the nano dialysis membrane tube 13.

[0032] Working principle: During use, let the blood enter the topmost group of collection chambers 20 through the topmost group of connecting pipes 21, then the blood enters the inside of each group of nano dialysis membrane tubes 13, then the blood enters the bottommost group of collection chambers 20, and is then discharged through the bottommost group of connecting pipes 21. During the process, control the dialysis fluid to enter the infusion chamber 14 through the connector pipe 18 at the bottom of the infusion chamber 14, then the dialysis fluid gradually enters each arc-shaped compartment 12 inside each separation compartment 11 through the liquid inlet through-hole 16, and then the dialysis fluid flows along the guide of the arc-shaped compartment 12 and contacts the part of the nano dialysis membrane tube 13 located inside this group of arc-shaped compartments 12 during the process, so as to purify the blood passing through this section inside the nano dialysis membrane tube 13. Then the dialysis fluid with metabolites and toxic substances enters the drainage chamber 15 through the liquid inlet through-hole 16 and is discharged through the connector pipe 18 at the top of the drainage chamber 15.
