Description

Technical Field

[0001] The utility model relates to the technical field of hemodialyzer production, and more specifically to a loading and unloading system for a preassembled dialyzer entering a centrifugal sealing and filling process. Background Art

[0002] The hemodialyzer (hemodialyzer for short) is the core device in the hemodialysis process. It is mainly composed of a membrane bundle, an outer shell, a sealing layer and end caps. The membrane bundle is placed in a transparent cylindrical outer shell, and the two sides are sealed with non-toxic medical polyurethane adhesive and fixed to the outer shell. The membrane bundle opens outside the sealing layer, and the outer end is screwed closed with a cover to form a blood chamber. The top of the cover is open to connect the inlet and outlet of the blood circuit. The space formed by the dialyzer outer shell and the polyurethane adhesive sealing layers on both sides is divided into a blood chamber and a dialysate chamber by the membrane bundle. There are inlets and outlets for the dialysate on both sides of the outer shell. When in use, the outlet and inlet of the blood chamber are respectively connected to the venous tube and arterial tube of the blood circuit, and the flow direction of the dialysate in and out is opposite to that of the blood.

[0003] In the hemodialysis machine assembly production line, after the dialyzer has gone through the pre-assembly process, the membrane bundle has been placed in the outer shell, and sealing caps are installed at both ends to form a pre-assembled dialyzer, which is then unloaded into the transfer box. When the traditional pre-assembled dialyzer is unloaded into the transfer box, it is usually manually carried to the transfer box to the centrifugal sealing process. The pre-assembled dialyzer is manually clamped on the turntable in the centrifugal sealing process, and the dispenser is manually placed. The motor drives the turntable to rotate at high speed centrifugally, so that the polyurethane glue passes through the dispenser and is "thrown" to both ends of the dialyzer shell to achieve sealing. After the sealing and pouring of the glue is completed, it is still necessary to manually remove the dispenser, dialyzer, etc. in turn. It can be seen that the loading and unloading work of the pre-assembled dialyzer entering the centrifugal sealing process is all done manually, with high work intensity and serious occupation of human resources.
