Super-miniature dialyzer for clinical animal research and method for manufacturing super-miniature dialyzer

The invention relates to a super-miniature dialyzer for clinical animal research. The super-miniature dialyzer comprises a tubular shell. An inlet-end blood cap and an outlet-end blood cap cover two ends of the tubular shell, a blood inlet tube is arranged on the inlet-end blood cap, a blood outlet tube is arranged on the outlet-end blood cap, a dialysis liquid outlet tube and a dialysis liquid inlet tube are arranged on the outer side walls of the two ends of the tubular shell, a hollow fibrous membrane bundle is arranged inside the tubular shell, and space yarns are arranged among membrane bundles of hollow fibrous membranes at intervals. The invention further discloses a method for manufacturing the super-miniature dialyzer. The method includes steps of inserting membranes; sintering one end of the hollow fibrous membrane bundle; covering the end of the hollow fibrous membrane bundle with technological caps; injecting glue into the end of the hollow fibrous membrane bundle; curing the glue; shearing the end of the hollow fibrous membrane bundle; covering the tubular shell with the blood caps; sintering the other end of the hollow fibrous membrane bundle; covering the other end of the hollow fibrous membrane bundle with technological caps; injecting glue into the other end of the hollow fibrous membrane bundle; curing the glue; shearing the other end of the hollow fibrous membrane bundle; covering the tubular shell with technological caps; smearing seal glue and the like. The super-miniature dialyzer and the method have the advantages that the blood purification efficiency can be effectively improved by the aid of the super-miniature dialyzer and the method; the space yarns are arranged among the membrane bundles, accordingly, dialysis liquid can be in sufficient contact with the dialysis membranes, and the blood purification efficiency can be improved.
