Embodiment 1

[0033] Such as figure 1 As shown, the dialyzer provided by the embodiment of the present invention includes: a filter medium 1 and a dialyzer housing 2. The filter medium 1 is arranged in the dialyzer housing 2 and extends along the axial direction of the dialyzer housing 2.

[0034] Specifically, the curved filter medium 1 is inserted into the dialyzer housing 2, so that the effective length of the filter medium 1 can be increased without increasing the volume of the dialyzer housing 2, thereby increasing the effective membrane area.

[0035] In the embodiment of the present invention, the filter medium 1 includes membrane filaments 11, and multiple membrane filaments 11 are spirally distributed along the axis of the dialyzer housing 2. Among them, the plurality of membrane filaments 11 are spirally distributed along the axis of the dialyzer housing 2, thereby ensuring that the plurality of membrane filaments 11 are closely attached, so that the number and length of the membrane fi...

Embodiment 2

[0061] Such as Figure 4 As shown, the dialysis device provided by the embodiment of the present invention includes: a dialysis machine 3, a peristaltic pump 4, a simulation fluid tank 5, and the dialyzer provided in Embodiment 1. The simulation fluid tank 5, the peristaltic pump 4, and the dialyzer are in fluid communication in sequence, The dialysis device is in fluid communication with the dialysis machine 3. Among them, the peristaltic pump 4 is used to suck out the simulated liquid from the simulated liquid tank 5, or to draw blood from the patient, and to introduce the simulated liquid or blood into the dialyzer; the dialysis machine 3 is used to introduce the dialysate into the dialyzer, and It is discharged after flowing through the dialyzer.

[0062] It should be noted that the dialyzer assembled with parallel membrane bundles and twisted membrane bundles is subjected to in vitro simulation experiments to simulate the dialysis process of patients with end-stage renal dis...

Embodiment 3

[0075] The manufacturing method of the dialyzer provided by the embodiment of the present invention includes the following steps: membrane bundle spinning: the two ends of the membrane bundle are respectively rotated around the axis of the membrane bundle in opposite directions; the membrane bundle loading: loading the rotated membrane bundle on the dialyzer housing 体2内。 In the body 2. Among them, by twisting the membrane bundle in the opposite direction, the effective length of the membrane filament 11 can be increased, thereby increasing the effective length of the membrane filament 11 in the dialyzer housing 2 of a certain volume.

[0076] Further, the angle at which one end of the membrane bundle rotates relative to the other end of the membrane bundle is greater than or equal to 360 degrees. Specifically, the membrane bundle is twisted at least once to obtain a larger effective length of the membrane filament 11.

[0077] Further, the manufacturing method of the dialyzer furthe...

Abstract

The invention provides a dialyzer, a dialysis apparatus and method for manufacturing a dialyzer and relates to the technical field of medical instruments, The dialyzer according to the present invention, includes a filter medium and a dialyzer housing, a filter medium is disposed in the dialyzer housing, and bends and extends in the axial direction of the dialyzer housing, a dialyzer according tothe present invention. The invention solves the technical problem that the effective membrane area of the dialyzer is difficult to increase, increases the length and size of the filter medium in a certain volume, achieves the purpose of increasing the effective membrane area, and enlarges the effective membrane area and improves the performance of the dialyzer in the same dialyzer shell compared with the method of fixing the effective membrane area in parallel to the dialyzer shell.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a dialyzer, a dialysis device and a method for manufacturing the dialyzer. Background technique [0002] At present, hemodialyzers, hemodialysis filters, hemodialysis filters, blood filters, plasma separators, etc. mostly use hollow fiber membrane dialyzers, which use tens of thousands of parallel membrane filaments or membrane bundles containing yarns, which are packed in polycarbonate in parallel. In the case of ester (PC) or polypropylene (PP), then use polyurethane glue to fix the two ends of the membrane bundle. After the polyurethane glue is cured, cut both ends smoothly, add the sealing ring, tighten the end cap, and assemble it into a complete Dialyzer. Due to problems in product design and other aspects, when the membrane filaments are produced, micro waves or yarns need to be added to allow the dialysate to penetrate into the membrane filaments more evenly...
