Abstract
The utility model aims at providing a hemodialyzer with a mortise and tenon type seal covering shell, wherein the hemodialyzer is simple in manufacturing, even in dialysis and good in seal performance. The problem that flow speed is not even due to the fact that blood impacts ports and hollow fibrous membranes in a dialysis process can be avoided. According to the hemodialyzer with the mortise and tenon type seal covering shell, the problem that the flow speed is not even due to the fact that blood impacts the ports and the hollow fibrous membranes in the dialysis process can be avoided, a high-seal mortise and tenon type shell cover is developed, seal performance is improved, and convenience of manufacturing is improved. The hemodialyzer with the mortise and tenon type seal covering shell comprises a shell body and a cover, shell body mortises are arranged at the upper end portion of the shell body, cover tenons are arranged at the lower end portion of the cover, and the shell body mortises and the cover tenons are matched mutually. A plurality of hollow tows are arranged in the shell body, wherein gum is used at one end of each hollow tow, inner cavities of the hollow tows form blood pathways, blood is led out through a blood port at the upper end portion of the cover, gaps of the hollow tows and an inner cavity of the shell body form dialyzate pathways, and the dialyzate is led out of a dialyzate drainage port on one side of the shell body.
Description
Technical field
The present invention relates to a kind of armarium, especially a kind of hemodialyzer of tenon coupling sealing sheath body.
Background technology
Blood purification (Blood Purification) or blood adsorbing therapy (Therapeutic Apheresis, TA), it is hemodialysis, be that the another kind that belongs to outside the Drug therapy is selected, its basic principle is blood to be extracted out, through special filter membrane, the toxin that will remove or material are filtered out, again blood is sent back in the body.On treatment of diseases, blood purification treatment will be important and effective, and the Therapeutic Method that is used in a large number.At present blood purification treatment has used what kidney, liver, and the too high treatment of blood fat fat, the anti-repulsion course for the treatment of when also can be used for organ transplantation simultaneously.In the near future, blood purification treatment also will be used for the treatment of the removing of body inner virus, and cause the factor that excessively intensifies of immunity because of influenza virus; The removing of cytotoxin (Cytokine); Other reach peripheral blood circulatory diseases etc. as tumor, apoplexy.The clinical application of blood purification continues in research and development, and potentiality and the market business opportunity of development will be promising.
Seeing through at present hemodialyzer, to carry out blood purification quite general now, and the leading role of blood purification in present medical institutes is hemodialyzer, the sleeve that the prior art utilization is packaged with hollow-fibre membrane separates blood pathway and dialysate circuit through mechanism design, forms hemodialyzer.Use in a large number after the approval of such dialyser process health competent authority, yet on application surface, still exist dialysate circuit and blood pathway can produce inhomogeneous flow velocity and the inhomogeneity problem of dialysing.
Summary of the invention
The purpose of this invention is to provide a kind of tenon coupling even, good airproof performance of making simply, dialyse and seal the hemodialyzer of sheath body, can avoid dialysis procedure blood impact port and hollow-fibre membrane to cause the flow velocity inequality.The present invention designs through the parsing of transport phenomena and quality transmission and can avoid dialysis procedure blood impact port and hollow-fibre membrane to cause the flow velocity inequality, further see through the present invention and develop high sealing trip cap increase sealing, can increase the convenience of manufacturing simultaneously.
The present invention is achieved in that a kind of hemodialyzer of tenon coupling sealing sheath body, comprise housing and upper shield, it is characterized in that described housing upper end is provided with housing trip (mother), described upper shield bottom is provided with upper shield trip (public affairs), and described housing trip agrees with mutually with the upper shield trip; Be provided with the hollow tow (formation hollow fiber membrane) that a plurality of ends adopt the glue envelope in the described housing, hollow tow inner chamber forms blood access, blood port via the upper shield upper end is derived, macaroni yarn interfascicular crack and housing inner chamber form the dialysis solution path, derive via the dialysis solution draining hole of housing one side.
Disclosed a kind of hemodialyzer with tenon coupling sealing sheath body mainly is to see through the purpose that trip male and female sheath body reaches high sealing and easy assembleability.
Disclosed a kind of hemodialysis implement body implementation type formula with tenon coupling sealing sheath body mainly has the roughly sheath body housing of tubular of a both ends open, and the nearly opening part in housing two ends respectively is provided with a port; Two can with the shell upper shield of this housing seal ground combination; A plurality of the hollow fiber membrane that empty tow is formed among this housing of what is set, this hollow fiber membrane and gateway, two ends utilize the glue sealing fixed; And the gap of this inner walls and hollow fiber membrane forms first stream and this hollow fiber membrane inner chamber forms second stream.
Preferably, but but this first stream drain dialysis solution and this second stream drain blood forms hemodialyzer.
Preferably, this housing be combined with feud, shell upper shield ground can see through rubber ring or falope ring or directly sealing by fusing reach.
Preferably, this hollow tow is for having hollow fiber or polymeric catheter among the hole.
More preferably, this doughnut is selected from the macromolecular fibre by polysulfones, polysulfones ester, polyester, polymethyl acrylate, poly-ring grease, polyureas ester, polyethers.
In sum, the present invention is that a kind of tenon coupling even, good airproof performance of making simply, dialyse seals the hemodialyzer of sheath body.
