Abstract
The utility model provides a separating type hemodialysis absorber. The separating type hemodialysis absorber comprises an outer shell, an artery end, a vein end, a filtering part and a perfusion part, wherein the artery end and the vein end are connected with the outer shell, the filtering part comprises a dialysate passage and a blood passage, and the perfusion part comprises an absorbing layer and a filtering film which are arranged inside the outer shell. The separating type hemodialysis absorber has the advantages of being conveniently used for clinic treatment, being capable of removing medium and small molecular toxin in the body of a patient, absorbing macromolecular toxin, being capable of effectively avoiding the situation of blood seepage, and being simple in structure, low in machining cost, high in production efficiency and the like.
Description
Technical field
This utility model belongs to medical instruments field, especially relates to a kind of dialysis adsorber with adsorption function.
Background technology
Dialyser in existing technology (using during hemofiltration) is two separated apparatuses of function with adsorber (using during hemoperfusion).Hemofiltration is by machine or patient's self blood pressure, makes the filter of blood flow in extracorporeal circuit, leaches large quantity of fluid and solute, i.e. ultrafiltrate under the effect of filtration pressure; Meanwhile, supplement the electrolyte solution similar to blood plasma liquid component, i.e. displacement liquid, to reach the object of blood purification.Hemoperfusion is by adsorbent, to remove endogenous and exogenous poisonous substance by outside blood samples of patients lead body, reaches the Therapeutic Method purifying the blood.If clinical, need to do hemodialysis and perfusion simultaneously, can only be by two apparatus series connection, operation inconvenience, because connecting, closely there is not blood leakage phenomenon in occasional.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of separate type hemodialysis adsorber, and especially compatible blood dialysis, filtering therapy carry out simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of separate type hemodialysis adsorber, comprise shell, the arterial end being connected with shell and vein end, filtration fraction and perfusion part, filtration fraction comprises dialysis solution passage and blood channel, and perfusion partly comprises setting adsorption layer and filter membrane in the enclosure.
Further, blood channel is comprised of arterial end, several cellosilk and vein end.
Further, dialysis solution passage comprises dialysis solution entrance and the dialysis solution outlet that is arranged on side wall of outer shell.
Further, dialysis solution passage is by dialysis solution entrance, and shell is with interior, cellosilk space in addition, and dialysis solution outlet forms.
Further, arterial end and vein end are oppositely arranged on shell two ends.
Further, filter membrane is arranged near vein end exit.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, in the time of can facilitating clinical treatment, use, can remove the small molecular toxin in patient body simultaneously, and macromole toxin in simultaneously adsorbing, and can effectively avoid blood leakage situation; Have simple in structurely, processing cost is low, production efficiency advantages of higher.

The specific embodiment
As shown in Figure 1, this utility model is a kind of separate type hemodialysis adsorber, the arterial end 1 that comprise shell, is connected with shell and vein end 2, filtration fraction and perfusion part, filtration fraction comprises dialysis solution passage and blood channel, and perfusion partly comprises setting adsorption layer 4 and filter membrane 3 in the enclosure.
Blood channel is comprised of arterial end 1, several cellosilk 6 and vein end 2.
Dialysis solution passage comprises dialysis solution entrance 5 and the dialysis solution outlet 7 that is arranged on side wall of outer shell.
Dialysis solution passage is by dialysis solution entrance 5, and shell is with interior, cellosilk 6 space in addition, and dialysis solution outlet 7 forms.
By the outer shell extension of original dialyser, normally fill after dialyser cellosilk, in vacant part, add adsorbing material, as active carbon, resin, cellulose etc.
Hemodialysis part can be selected hollow fibre type, coil-type and plate 3 kinds.Preferably hollow fibre type, is comprised of 1～1.5 ten thousand hollow fibre silk, and the wall of hollow fibre silk is dialyzer, tool semipermeable membrane character.During hemodialysis, blood flows in every hollow fibre silk, and dialysis solution flows through outward at every hollow fibre silk, and the flow direction of blood and the dialysis solution opposite direction that flows, removes poisonous substance by semipermeable membrane principle, by ultrafiltration and permeate removing moisture.
The work process of this example: patient's blood and dialysis solution are introduced to separate type hemodialysis adsorber of the present utility model simultaneously, make both flow directions contrary, utilize semipermeable membrane wherein, the too much toxin of accumulating in blood and too much moisture are cleared out external, and supplementary base is to correct acidosis, adjust electrolyte disturbance, substitute the excretory function of kidney; Poisonous substance in blood, medicine, metabolite etc. are adsorbed by adsorption layer of the present utility model simultaneously, reach the blood purification effect of removing these materials.
By device of the present utility model, hemodialysis, filtering therapy are carried out simultaneously.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
