Abstract
The utility model provides an integrated hemodialysis absorber which 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 channel, a blood channel and a dialysis membrane between the dialysate channel and the blood channel, and the perfusion part is arranged on an adsorption layer on the dialysis membrane. The integrated hemodialysis absorber has the advantages that the absorber can be used for clinical treatment conveniently, middle-and-small molecule toxin in a patient can be removed, middle-and-large molecule toxin is absorbed at the same time, the structure is simple, processing cost is low, and production efficiency is high.
Description
Technical field
This utility model belongs to medical instruments field, especially relates to a kind of dialyser or filter 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 integral type blood dialysis adsorber, and especially compatible blood dialysis, filtering therapy carry out hemoperfusion simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of integral type blood dialysis adsorber, comprise shell, the arterial end being connected with shell and vein end, filtration fraction and perfusion part, filtration fraction comprises the dialyzer between dialysis solution passage, blood channel and above-mentioned two passages, and perfusion is partly for being arranged on the adsorption layer on dialyzer.
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, described adsorption layer is arranged on cellosilk wall.
Further, arterial end and vein end are oppositely arranged on shell two ends.
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 macromole toxin in absorption simultaneously; Have simple in structurely, processing cost is low, production efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure:
1, arterial end 2, shell 3, vein end
4, dialysis solution entrance 5, cellosilk 6, dialysis solution outlet
The specific embodiment
As shown in Figure 1, this utility model is a kind of integral type blood dialysis adsorber, comprise shell 2, the arterial end 1 being connected with shell 2 and vein end 3, filtration fraction and perfusion part, filtration fraction comprises the dialyzer between dialysis solution passage, blood channel and above-mentioned two passages, and perfusion is partly for being arranged on the adsorption layer on dialyzer.
Blood channel is comprised of arterial end 1, several cellosilk 5 and vein end 3.
Dialysis solution passage comprises dialysis solution entrance 4 and the dialysis solution outlet 6 that is arranged on shell 2 sidewalls.
Dialysis solution passage is by dialysis solution entrance 4, and shell 2 is with interior, cellosilk 5 space in addition, and dialysis solution outlet 6 forms.
Described adsorption layer is arranged on cellosilk 5 walls.Cellosilk wall has the effect of dialysis and absorption concurrently.
Arterial end 1 is oppositely arranged on shell 2 two ends with vein end 3.
When making dialyser cellosilk, add part adsorbing material, as active carbon, resin, cellulose etc.
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-be cellosilk wall, 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 the adsorption layer in cellosilk wall 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.
