Embodiment 1

[0037] A kind of preparation technology of dialyzer, such as figure 1 shown, including the following steps.

[0038] A Install the filling rubber ring, and put the filling rubber ring on the two ends of the dialyzer shell. Before filling the apron, first check whether there are black spots, burrs and other defects in the dialyzer shell. If there are similar defects, discard the dialyzer shell and replace it with another one.

[0039] B Install the membrane, put the dialysis membrane into the dialyzer casing, and the two ends of the dialysis membrane are exposed from the dialyzer casing. The dialysis membrane is usually a polyethersulfone membrane.

[0040] C Sealing film, heat-sealing the two ends of the dialysis membrane loaded into the dialyzer housing. Specifically, the dialyzer is fixed in the clamp of the film sealing machine, and the film is sealed with the film sealing machine.

[0041] Turn on the sealing machine for 2-5 minutes, put the dialyzer with the dialysis ...

Embodiment 2

[0053] Such as figure 2 As shown, in order to improve product efficiency, in addition to steps A to H in Example 1, a detection step I can also be added after step H.

[0054] Step I detects, specifically comprises:

[0055] Moisturizing membrane: After filling the dialyzer with water, let it stand to make the dialysis membrane in the dialyzer fully wet.

[0056] Wetting the membrane is specifically, place the dialyzer horizontally on the filling fixture of the automatic filling machine, inject water for 1-3 minutes, remove the dialyzer horizontally and let it stand for 8-12 minutes to fully wet the dialysis membrane in the dialyzer.

[0057] Air test: connect the trachea to one end of the dialyzer to inflate the dialyzer, the water in the dialyzer flows out from the other port of the dialyzer, observe the change of the air pressure in the dialyzer to judge whether the dialyzer is a qualified product.

[0058]Specifically, place the dialyzer vertically on the gas testing ma...

Abstract

The invention discloses a process for preparing a dialyzer, which comprises the following steps of: A, assembling colloid injecting rings, namely sheathing the colloid injecting rings at two ends of a dialyzer shell; B, filling a membrane, namely filling a dialysis membrane into the dialyzer shell, wherein two ends of the dialysis membrane are exposed out of the dialyzer shell; C, sealing the membrane, namely thermally sealing the two ends of the dialysis membrane filled into the dialyzer shell; D, assembling colloid injecting covers, namely assembling the colloid injecting covers on the colloid injecting rings at the two ends of the dialyzer shell, wherein a distance is formed between the colloid injecting covers and the end faces of the dialysis membrane; E, injecting colloid, namely injecting the colloid into the dialyzer shell; F, performing centrifugal treatment, namely performing centrifugal treatment on the colloid injected dialyzer so that the colloid is uniformly distributed in the two ends of the dialyzer shell; G, cutting the membrane, namely after the colloid in the dialyzer is solidified, taking down the colloid injecting covers at the two ends of the dialyzer shell, and cutting the two ends of the dialysis membrane; and H, assembling end covers, namely assembling the end covers at the two ends of the dialyzer shell. The process for preparing the dialyzer is convenient to process, and has the characteristics of low cost, high yield and good quality.

Description

technical field [0001] The invention relates to the technical field of dialyzers, in particular to a preparation process of dialyzers. Background technique [0002] Dialyzer, commonly known as artificial kidney, has been widely used clinically. By performing hemodialysis, the patient's life can be appropriately extended. A dialyzer usually includes a housing, a hollow fiber arranged in the housing, a blood inlet pipe, a blood outlet pipe, a dialysate outlet pipe and a dialysate inlet pipe arranged at both ends of the housing. [0003] In the prior art, the production of dialyzers is completed by manual operations in different procedures, which not only has low production efficiency, but also makes it difficult to guarantee product quality. Therefore, there are defects such as high cost and low production efficiency. [0004] Therefore, in view of the deficiencies of the prior art, it is necessary to provide a dialyzer manufacturing process to overcome the deficiencies of t...
