Description
Technical Field

Background
Hemodialysis is to introduce the blood and dialysate of a patient into a dialyzer at the same time by utilizing the principle of a semipermeable membrane, wherein the blood and the dialysate flow in opposite directions on two sides of the dialysis membrane, and the aims of removing toxins in the blood and excessive water retained in the body, supplementing substances required in the body and maintaining the balance of electrolytes and acid and alkali are fulfilled by means of mechanisms such as dispersion, convection, sieving and the like. The dialyzer mainly comprises a support structure and a dialysis membrane. Depending on the shape and mutual arrangement of the support structure membranes, dialyzers which have historically appeared one after the other can be essentially divided into three categories: flat plate type, flat tube type and hollow fiber type. Wherein, the hollow fiber type dialyzer is the dialyzer with the most clinical use and the best effect at present. The hollow fiber dialyser needs to be filled with tens of thousands of hollow fibers, so that the packaging difficulty of the hollow fiber dialyser is higher than that of other two dialysers. After the hollow fiber membrane is filled into the dialyzer shell, the hollow fiber membrane needs to be fixed at two ends of the shell in a centrifugal glue injection mode so as to complete the combination of the shell and the hollow fiber membrane.
The existing dialyzer centrifugation technology adopts 2-3 products which are arranged in a centrifugal device in a crossed manner, and the simultaneous end sealing of two ends is finished by one-time glue injection. However, this requires both the length of the dialyzer and the rotational speed of the centrifuge, for example, the method is suitable for use with housing lengths of greater than 180mm and centrifuge speeds of not less than 800 r/min.
