Problems solved by technology

[0003] Dialyzers are medical devices, and whether their quality is qualified or not is very important, which will affect the therapeutic effect and safety of treatment. If there are defective products in the dialyzers shipped out of the factory, these dialyzers with potential quality problems will not only improve the medical market after they enter the medical market. Product failure rate and, more importantly, reduces the safety of hemodialysis treatment

Embodiment approach

[0118] As an optional embodiment of the present invention, the quality inspection method further includes checking whether the hollow fiber membranes are blocked, and whether the hollow fiber membranes are blocked is detected before the end cap and the tank body are assembled together. After the tank is injected, centrifuged, cured and cut, the two ends of the hollow fiber bundle will form an opening at the port of the tank. On the detection image, the opening is represented as a circle, such as Figure 4 As shown, the white circle is the opening formed by the hollow fiber membrane, and the area filled with oblique lines is the sealant; under normal circumstances, after the sealant is cut, the two ends of the hollow fiber bundle will be cut to form an opening. If the holes and openings are filled with sealant, the circles in the detection image will be filled with oblique lines, so that which hollow fiber membranes are clogged can be accurately identified. Further, if the numb...

Abstract

The invention discloses a quality inspection method and an assembling method of a dialyzer. The dialyzer comprises a tank body and end cover assemblies arranged at the two ends of the tank body; a hollow fiber bundle is arranged in the tank body and filled with sealant, the hollow fiber bundle comprises a plurality of hollow fiber membranes, and each end cover assembly comprises an end cover and a sealing ring; before the tank body and the end cover assembly are assembled, AOI detection is carried out on the tank body, and the method comprises the following steps that images of the two end portions of the tank body are collected through an image collector; and according to the collected detection image, performing AOI detection on the tank body, and judging whether the quality of the tank body is qualified or not. In the process of assembling the dialyzer, the quality inspection method of the dialyzer is applied to the assembling process so as to accurately identify the defects of the tank body, eliminate defective products in the production process of the tank body and reduce the production failure rate of the dialyzer in time, so the aim of considering the safety and the efficiency in the production process of the dialyzer is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a quality detection method and an assembly method of a dialyzer. Background technique [0002] A dialyzer is a medical device used in hemodialysis treatment. Such as figure 1 As shown, when in use, human blood is transported into the dialyzer 10 through the blood channel input conduit 10a, and the dialysate is transported into the dialyzer through the dialysate input conduit 10b, and the dialyzer 10 is provided with a dialysis membrane, and the human blood and the dialysate are reversed. The direction is transmitted in the dialyzer 10 and flows through both sides of the dialysis membrane respectively. The solute and water on both sides of the dialysis membrane move across the membrane under the concentration and pressure gradient to exchange substances, so that the metabolic accumulation of urea, creatinine, Guanidines, acid radicals and excess electrolytes ...
