Description
Technical field
The utility model relates to a kind of using ultrafilter and the dialyzate high-efficient purification reuse system of adsorption cleaning combination technique
System belongs to apparatus for purifying blood technical field.
Background technique
Haemodialysis is a kind of external dialysis treatment for filtering toxin from the blood of patient using haemodialysis control unit.At present
Most of haemodialysis control units generally comprise computer, fluid pump, blood lines, dialysate lines, dialyzer and for discharging
The tapping line of dialysis solution.It connect the circulatory system of patient with haemodialysis control unit by conduit or fistula needle, and by patient
Blood be continuously pumped through haemodialysis control unit.Blood passes through the dialyzer comprising semi-permeable membrane in haemodialysis control unit.Half
Permeable membrane separates the blood of side and the dialysis solution at another layer.Dialyzer removes waste, toxin and excessive from blood
Water, purified blood return to human body.Waste product and toxin are transferred in dialysis solution by semi-permeable membrane from blood, and single is saturating
Dialyzate about 90-120 liter used in analysis processing discharges after then directly abandoning or handle.Obviously, a large amount of used dialysis
Liquid will increase the cost of dialysis.The object being introduced into blood flow due to the needs that dialyzate can also include various concentration by diffusion
Matter, such as drug, glucose, when these components pass through dialyzer can not completely into blood, thus also can some with useless
The dialyzate of abandoning is discharged；In addition, there are also the beneficial components of some pairs of human bodies to enter discarded dialyzate by semi-permeable membrane in blood.
Above-mentioned various factors causes the increased costs of haemodialysis, waste to increase, and also can cause environmental pollution.Therefore, it produces not
Few dialyzate recovery and utilization technology, typical technology are as follows:
A kind of dialysate regeneration system for portable human dialysis of Chemica Technologies Inc., U.S. application, in
State's number of patent application is 200480038117.3, and the request for data of PCT application is PCT/US2004/043546
(2004.12.22) was authorized, Authorization Notice No. CN1897993B, core technology flow diagram on February 08th, 2012
As shown in Fig. 1.The key technology of the patent uses a kind of dialysate regeneration room 14, can selectively retain toxin and repel
The toxin trap of the cation of selection, wherein the ion selection urase that the toxin trap includes ion selection barrier is fixed
Activated carbon fiber.The advantages of technology is that process is simple, structurally reasonable, easy to carry.But it also has the shortcomings that certain: due into
It is big to enter the low thus required adsorbent adsorption area of toxin concentration in the dialyzate of dialysate regeneration room, the suction of unit volume
Attached dose of adsorption efficiency is lower, and adsorbent inventory is more.
Chinese patent (application number: 201510106383.5) provides a kind of dialysate regeneration device, using reverse osmosis group
Part and electric catalysis reactor based on BDD electrode utilize the very wide potential window of the electric catalysis reactor based on BDD electrode and low
Adsorption capacity, oxidation process is very efficient, effectively can convert and remove waste product and toxin in dialyzate, device it is continuous
Runnability is good.But its also have the shortcomings that it is certain, if electric catalysis reactor may following components generate catalytic action, cause to become
Property or generate the substance that is harmful to the human body, such as penetrate the blood of human body Hubeiwan of dialyzate, be not fully utilized in dialyzate
Needs pass through the substance (such as drug or glucose) that is introduced into blood of diffusion.
(application number: 201710823579.5) providing a kind of device applied to haemodialysis to Chinese patent, typical
Flow chart is as shown in Fig. 2.The device is using the adsorbent for including specific adsorption material and/or non-specific adsorption material
The system and method for the dialysate regeneration that the fluid purification component of box body and reverse osmosis film water purification technique combines.Wherein, it inhales
Specific adsorption material in attached dose of box body becomes in absorption without any chemistry mainly for the absorption of urea in dialysis liquid
Change, the accumulation of any ion will not be generated；Non-specific adsorption material in adsorbent box body is for micro in dialysis liquid
The removal of the substances such as metal ion, kreatinin, β 2M uric acid, micro-content organism.After dialysis liquid removes impurity by adsorbent box body
Following cycle is carried out after influent purification assembly is further purified by reverse osmosis membrane again.The advantages of technology is can be very big
Cost is reduced, is conserved water, and is portable small and exquisite, can meet patient simultaneously the hospital and family the needs of.But it also has centainly
The shortcomings that, i.e., by the dialyzate of adsorbent box body when passing through the fluid purification component of reverse osmosis film water purification technique, formed
Lean solution two parts based on rich solution and pure water rich in macromolecular substances, rich solution are discharged as waste, need in the process periodically
Or continuous moisturizing；It needs dialyzate constituent adjustment system that processing is adjusted by the reuse dialyzate of fluid purification component, adjusts
Section process is extremely complex.
Therefore how to solve the problems, such as above-mentioned technology, a kind of dialysate regeneration reuse of efficient absorption purification is provided
System becomes one of hot subject of the area research.
