Hematoma is one of the ways to replace kidney function replacement in patients with chronic and chronic renal failure. According to the physical blood night drainage method to the body, through a dialysis composed of countless hollow chemical fibers, the acid and alkali (dialysis solution) with a solution similar to the human concentration value (dialysis) Inside and outside chemical fibers, chemical substances are carried out according to the diffuse/thermal stream, and the body's metabolic waste, maintaining electrolyte solution and pH; at the same time, the body is too much water.

In 2017, China ’s hemodialysis machinery and equipment consumables operated nearly 10 billion, but still did not reach 5%of the global operating scale. Only 15%-20%of the last-stage renal failure patients accepted dialysis, and the analysis rate with global capitalism was 95%. The distance is large, and all the market prospects are large. At the same time, the work pressure of Chinese analysts has caused great entrepreneurial business opportunities.

The current hemodialysis contains the outer shell and dialysis membrane. The two sides of the dialysis membrane are fixed through epoxy resin glue and are not moved in the two sides of the shell, and the dialysis membrane is proportioned in the shell. The outer shell contains the tubular subjects with the end cap and the two -sided diameter exceeding the middle diameter. The tubular subject is equipped with a dialysis liquid to enter the connected interface and the output interface of the dialysis solution. There are blood night keys to enter the connected interface and blood night output interface. During the installation, the epoxy resin glue between the end cover and the tubular subject fixes the non -dynamic dialysis membrane is equipped with a sealing ring.

The manufacturing method of hemodialysis contains: pre -assembly, burn, centrifugal tank, cut head, fix the end cover, fix the end cover on the subject, leakage, drying treatment, and assembly.

        1. Pre -assembly

        The entire process of pre -patching is to install the dialysis membrane beam containing a plastic film bag into the tubular subject, and the fixed short fiber is disconnected from the plastic film at the same time.

        2. Burning

        The entire process of burning is to burn the pre-assembled dialysis membrane from the infrared thermar at 700 ° C-900 ° C, so that the two sides of the dialysis membrane are closed.

        3. Corporation seal

        The entire process of centrifugal seal is a full-automatic and fast centrifugal sealing machine, and a certain amount of epoxy resin glue is introduced into both sides of the tubular subject, and the heart type is 1-10 minutes at 60 ° C-90 ° C.

        4. Cut your head

        The whole process of cutting heads is to use CNC machine tool to rotate automatic cutting machines to remove unnecessary epoxy resin on both sides of the tubular subject.

        5. The end cover is fixed

        The entire process of installing the end cover is fixed and not moved in the tube -like main body. Connect and tighten the sealing circular card in the cervical vein of the internal hole of the epoxy resin.

        6. Discover

        The whole process of leakage is to enter a certain working pressure in the large -time chemical fiber in the diarrhea, measure the pressure reduction of the voltage, and ensure that there is no pore eye disadvantage in the internal cavity of the hollow chemical fiber.

        7, drying treatment

        The entire process of drying treatment is to remove the dialysis of the leakage standard at 80 ° C-100 ° C to remove the residual water.

        8. Installing pollution hat

        The whole process of assembling the pollution -proof cap is to seal the import and export trade of the diarrhea to avoid dirty things.

        The outer shell made of polycarbonate (PC) is used. There is a mixed probability of bisphenol A, and there is a micro -poison. At this stage, glass bottle and other products have been gradually prohibited. The end cover is connected to the main body according to the flange, and the sealing ring card is tightly on the surface of the epoxy resin glue end and completed the sealing, because the deviation of the specifications on the manufacturing and the actual hand deviation of the end cover and the tubular main body, the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover and the end cover. The tightening level of flange connections between the tubular subjects is different. Vibration or impact of the packaging and transportation process is likely to cause loosening. The patient's application is invalid and the risk of liquid leakage during the entire process of patient application.
