Description
Technical field
The present invention relates to a kind of film bundle sealed port of butt end method and closing device, belong to hemodialyzer manufacture technology field.
Background technology
Hemodialyzer mainly utilizes the principle of semipermeable membrane, the blood of patient and dialysis solution are introduced blood, blood dialyser simultaneously, both flow in opposite direction in the both sides of dialyzer, by the solute gradient of film both sides, osmotic gradient and hydraulic pressure gradient, too much moisture is detained to reach to remove in toxin and body, simultaneously required in added body material, and maintain the object of electrolyte and acid-base balance.
Need hollow-fibre membrane to be tied up bunchy in the manufacturing process of hemodialyzer, cut in flat rear loading main casing, then film bundle end face is sintered, to realize closing of film bundle end face blood channel.Usually laser sintered method, electric heating infrared sintering process or secondary injecting glue method is adopted to realize above-mentioned requirements in prior art:
Laser sintered method: it utilizes laser directly to expose to film bundle end face, and by the film silk in its high temperature melting sintering laser path, the impact of the method Stimulated Light energy, penetration power is limited, whole sealings of film bundle end face cannot be ensured, sintering energy consumption is higher simultaneously, and the maintenance cost of laser part is also larger;
Electric heating infrared sintering process: the thermo-effect of infrared radiation sintered membrane bundle end face that it utilizes hot plate to produce, in sintering process, hot plate and product keep not contacting, gluing after melting to prevent film silk bonds on hot plate, but offset because hot plate cannot contact with film bundle, therefore make sintered surface out-of-flatness, the sealing completely of film bundle end face cannot be ensured;
Secondary injecting glue method: it is by after main casing of being got one's things ready by film, hermetic glue cap seal has been utilized to live main casing two ends, when carrying out first time injecting glue, injecting glue amount is less, to guarantee that all film silk ports are all sealed, when after the end socket adhesive curing certain hour that first time injects, then carry out second time injecting glue, to reach good injecting glue effect; In the method injecting glue process, end socket glue amount is more, and manufacturing cost is also relatively high, and needs just can carry out second time injecting glue certain hardening time because of after first time injecting glue, and cause producing consuming time longer, efficiency is not high;
Three kinds of methods in sum, must use the Jiao Gai that can seal main casing termination completely, and glue lid must guarantee that end socket glue can not be revealed when follow-up centrifugal injecting glue, and this requirement causes the manufacturing cost of Jiao Gai to increase; And existing Jiao Gai is generally divided into lid (for sealing, being equivalent to cap top) and main body (connecting with housing, bottomless), before to product injecting glue, need the assembling carrying out Jiao Gai in two steps, operating process is loaded down with trivial details, and production capacity is low.
