Abstract
A PES hollow cored fibre hemodialyzer comprises: a blood entrance of the hemodialyzer, a blood cover of the hemodialyzer, a dialysate export, a shell of the hemodialyzer, a PFC hollow fiber-film bundle, a sealing ring, a seal glue, a dialysate resistance liquid board and an anti-rotation stent. The utility model is made of high polymer material, PFC hollow fiber-film bundle, which has better biocompatibility and dialysis function and better convection and dispersion properties. Eddy technology is adopted on the dialysis fluid resistance liquid board. Eddy current's agitation makes concentration of the dialysis liquid out of the dialysis membrane more uniform. Biocompatibility and dialysis effects are improved. Dialysis efficiency is improved. The anti-rotation stent can prevent bacteria from polluting. Meanwhile, when the utility model is laid flat, the liquid inside the hemodialyzer can be prevented from flowing out randomly.
Description
Technical field
This utility model relates to a kind of haemodialysis equipment of polyether sulfone hollow-fibre membrane, and this dialyser can carry out hemodiafiltration when the clinical treatment kidney disease, belong to technical field of medical instruments.
Technical background
Its structure of hemodialyzer of clinical treatment kidney disease is to install and use the cellulose hollow fiber film in the dialyser shell at present, and two ends are fixed with resin glue.Shell one end at dialyser has the blood inlet, and the other end has the blood liquid outlet, distolateral the dialysis solution inlet is arranged at one of shell, and another is distolateral the dialysis solution liquid outlet.This dialyser is when clinical use, and the blood pump of patients'blood by dialysis machine draws from tremulous pulse that the blood inlet of dialyser is made hollow-fibre membrane by cellulosic material after the dialyser outlet is got back in the patient body after the pipeline of dialysing is connected to.But because the biocompatibility of cellulose hollow fiber fibrous membrane is not high; Patient intravital in some molecule be difficult to remove, as B2M, this class material is detained the people that long-term dependence dialysis is survived and has very big harm in blood; Because of there being great amount of hydroxy group to exist, be easy to cause that complement activation makes the intravital leukopenia of patient in the fiber, cause the dialysis syndrome.
The dialysis solution of conventional dialysis device outlet at present generally is the blocking solution plate that faces dialysis fluid chamber, the normal employing symmetric form design of conventional dialysis device blocking solution plate, because of dialysis procedure liquid stream direction becomes symmetric form, the flow velocity on liquid stream both sides is under the bump that liquidates of hydrone, dialysate flow rate tends to impaired, particularly at the place, the hollow fiber bundle back side over against the dialysis solution mouth, flow velocity is very low.The low flow velocity of dialysis solution often makes with the inner blood constituent exchange of hollow fibre insufficient, influences the effect of convection current and disperse, reduces dialytic efficiency.
The conventional dialysis device generally is cylindric, and medical personnel are in the clinical manipulation process, and dialyser lies low and rolls easily when placing, can cause the dialysis solution mouth by germ contamination, if in the dialyser liquid is arranged, also make the temporary flow of liquid of dialyser come out easily, make troubles to medical personnel.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of hemodialyzer that adopts the polyether sulfone hollow-fibre membrane is provided.
This utility model is implemented in the following manner:
A kind of polyether sulfone hollow fibre hemodialyzer comprises the dialyser blood inlet; Dialyser blood lid; The dialysis solution outlet; The dialyser shell; Hollow fiber membrane bundle; Sealing ring; Sealing compound; The dialysis solution import; The blood outlet is characterized in that hollow fiber membrane bundle adopts macromolecular material polyether sulfone hollow-fibre membrane to make, and dialysis solution import one side that passes in and out sap cavity at dialyser is provided with the blocking solution plate, and the blocking solution plate has adopted the vortex patern liquid barrier.
For preventing to be flowed out, on the reverse side shell of dialyser liquid in-out mouth, increased an anti-rotation supporting structure by liquid in germ contamination and the dialyser.
The utlity model has following characteristics:
1, uses of the harm of cellulose hollow fiber film in order to solve to the patient, the polyether sulfone hollow-fibre membrane that we have adopted biocompatibility and the better novel high polymer material of dialysis function to make, because the effect of the oxygen-ether linkage in the polyether sulfone materials molecular structure, its hydrophilic and thermostability, decay resistance further improve, protein adsorption reduces when contacting with blood, especially when contacting, no longer produce basic free radical with strong oxidizer, activation to complement is few, has better convection current and disperse performance.
2, enter liquid eddy current direction and reduce the impact of liquid circlewise in the dialysis chamber in order to change dialysis solution to dialyzer, we have adopted exclusive dialysis solution eddy-current technique, and import one side that dialyser is passed in and out sap cavity is designed to blocking solution and changes the dialysis solution blocking solution plate of flow direction function.When dialysis solution entered dialyser, because the effect of blocking solution plate, liquid rotated into the dialyser inner chamber with blocking solution plate angle, because " stirring " of eddy current effect, make the outer dialysate concentration of dialyzer more even, dialysis solution has fully with dialyzer and contacts, and has improved dialytic efficiency.
Dialysis solution eddy-current technique of the present utility model has following effect:
1) effectively reduces the dialysis solution tunnel phenomenon, make the dialysis solution distribution and flow more even;
2) " stirring " of eddy current effect makes the outer dialysate concentration of dialyzer more even, increases convection current and dispersion effect, improves the clearance rate of medium and small molecule toxin;
3) dialysis solution is fully contacted with dialyzer, effectively increase contact area, the solute clearance rate is high and stable;
4) compare with the dialyser of no vortex technology, carbamide/flesh liver/phosphate/vitamin B12 clearance rate improves 5%～9%.Be the influence of checking eddy current to clearance rate, (test condition is super: filter flow velocity Q to have done corresponding test
F=10mL/min, blood flow Q
B=300mL/min, dialysate flow Q
D=500mL/min.), data contrast situation sees Table 1, and the result has the feelings dialyser carbamide/flesh liver/phosphate/vitamin B12 clearance rate of eddy current can improve 5%～9% from checking;
Test shows that the eddy current dialyser has certain anticoagulation function.
Table 1:
3, for prevent dialyser after the flushing since the round influence of in put procedure, arbitrarily rolling of shell use, we have increased an anti-rotation supporting structure 9 at the reverse side of dialyser liquid in-out mouth, prevent that the dialysis solution interface from contacting generation and infecting phenomenon with other article, can prevent that the liquid of dialyser inside from flowing out simultaneously.
