Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of extra-corporeal ultrafiltration loop.
Background technology
Congestive heart failure is the final Common end of many cardiovascular disease such as coronary heart disease, myocardial infarction, cardiomyopathy, hypertension, and the chronic progressive external pumping function of take clinically declines and fluid retention is feature.
Existing 5,000,000 Patients with Chronic Heart Failure of the U.S., year dead 500,000, be the topmost reason of being in hospital of over-65s crowd.The in-patient that the acute mistake compensatory heart failure of take is every year Main Diagnosis is 1,000,000 examples more.Heart failure is the sick maximum disease of spending of planting of medical policy, approximately 37,000,000,000 dollars of U.S.'s costs in 2009.The Epidemiological study demonstration of China in 2003, heart failure prevalence is 0.9%, and wherein male is 0.7%, and women 1.0%.The prevalence of 35-44,45-54,55-64 and 65-74 year age group is respectively 0.4%, 1.0%, 1.3% and 1.3%, and along with the age increases, heart failure prevalence significantly rises; The northern area of China prevalence is 1.4%, and southern area is 0.5%; City crowd is 1.1%, and rural population is 0.8%.The existing patients with heart failure of estimation China surpasses 8,000,000.Along with aged tendency of population, heart failure more and more becomes the great health problem of China, causes heavy society and financial burden.
The outstanding clinical manifestation of heart failure is retention of sodium and water.Fluid accumulation causes the internal organs such as lung, liver, intestinal and periphery compartment hyperemia, produces the series of symptoms such as dyspnea, and symptom drives patient's hospitalization.90% acute mistake compensatory heart failure be the volume load that causes thus overweight due to.Therefore, the primary goal for the treatment of is to eliminate too much sodium and water in body, reduces volume load.But, take diuretic at present as main Comprehensive Treatment, the retention of sodium and water that can not solve Patients with Cardiac Failure.U.S. ADHERE registration studies shows because losing in compensatory heart failure inpatient, 19% body weight increase, 49% 5 pounds of weight loss less thaies.Therefore, the diuresis of take at present can not effectively solve patient's fluid retention and congestive symptom as basic treatment way, even 1/5 patient increases the weight of, worsens.Total case fatality rate is high, needs repeated hospitalization treatment, 3 months again admission rate up to 24%-31%.A large amount of researchs show, the while in hospital is fully removed fluid retention, correct retention of sodium and water, are the critical treatment targets that reduces follow-up heart failure events.In view of many drawbacks of diuretic, clinically in the urgent need to finding new Therapeutic Method.

The specific embodiment
Below in conjunction with embodiment, the technical solution of the utility model is further elaborated.
Embodiment of the present utility model provides a kind of extra-corporeal ultrafiltration loop, as illustrated in fig. 1 and 2, comprises extracorporeal circulation blood circuit, for filtering and remove hemoconcentrator 4, ultrafiltration pipeline 3 and the ultrafiltrate collecting bag 5 of the unnecessary salinity of blood and water;
Extracorporeal circulation blood circuit comprises venous line 2 and arterial line 1;
Hemoconcentrator 4 is provided with blood entrance 401, blood outlet 402 and filtered solution outlet 403; Arterial line 1, venous line 2 and ultrafiltration pipeline 3 are connected with blood entrance 401, blood outlet 402 and filtered solution outlet 403 respectively;
Ultrafiltrate collecting bag 5 is connected with ultrafiltration pipeline 3 one end away from hemoconcentrator 4.
By arterial line 1, blood is caused in hemoconcentrator 4 by human body, can carry out ultrafiltration to blood, thereby the unnecessary salinity in removing blood (being mainly sodium salt) and moisture, blood after filtration is back in human body by venous line 2, and the filtered solution after filtering is by storing in ultrafiltration pipeline 3 suction ultrafiltrate collecting bags 5.Thereby can rapid recovery symptoms of heart failure, shorten the hospital stays, reduce admission rate again, there is good efficacy.
In ultra-filtration process, blood flow rate is less than 50ml/min, if blood flow too fast (as hemodialysis) can obviously increase the weight of heart burden, worsens cardiac function; Blood flow has been not enough to ultrafiltration too slowly.
Simultaneously, blood extracorporeal circulation volume (bloody path+concentrator) is less better, and the dialysis that routine is used clinically or the extracorporeal circulation volume of hemofiltration are up to 200～350ml, when treatment starts or treats end blood back, very large to circulating blood volume impact, can bring out or increase the weight of the heart failure state of an illness.
Therefore, preferred, hemoconcentrator 4 is 15～100ml with the total measurement (volume) of extracorporeal circulation blood circuit.So just, can reduce the impact of blood to circulating blood volume when treatment starts or treats end blood back, reduce the probability that brings out or increase the weight of the heart failure state of an illness.
Wherein, the volume of hemoconcentrator 4 is 5～30ml, and the volume of extracorporeal circulation blood circuit is 20～80ml.The volume of hemoconcentrator 4 is moderate, otherwise may affect velocity of blood flow or ultrafiltration effect.
Meanwhile, the internal diameter of extracorporeal circulation blood circuit and ultrafiltration pipeline 3 can be selected 2.8～3.2mm, and external diameter is 3.8～4.2mm, to meet above-mentioned requirements.
As shown in Figure 3, wherein, hemoconcentrator 4 preferably includes shell 404, for hollow fiber bundle 405 and two cappings 406 of filtering blood; The both ends open of shell 404; Two openings of two capping 406 difference shutoff, and sealing ring 407 sealings are set between capping 406 and opening;
Blood entrance 401 and blood outlet 402 are separately positioned in one of them capping 406; Filtered solution outlet 403 is arranged on the middle part of shell 404;
Hollow fiber bundle 405 is comprised of many doughnuts, and the end of all doughnuts all bonds together, and fills up the gap between described doughnut;
Two openings are stopped up respectively at the two ends of hollow fiber bundle 405, between the middle part of doughnut and housing 404 for leaching sap cavity 408;
The membrane area of doughnut is 0.08～0.3m
2.
Pass through said structure, just can make blood enter its inside by one end of doughnut, and filter by the fibre wall of doughnut, unnecessary salinity in blood (being mainly sodium salt) and moisture can enter and leach in sap cavity 408 through fibre wall, blood after filtering is flowed out by the other end of doughnut, completes filter process.
Membrane area has very important impact for velocity of blood flow and ultrafiltration effect, therefore, in order to guarantee velocity of blood flow and ultrafiltration effect, specially the membrane area of doughnut is chosen in to 0.08～0.3m
2scope in.
Shell 404 can be for cylindric, and capping 406 can be threaded connection with shell.
In order to reach good ultrafiltration effect, the material of doughnut is preferably polysulfones or polyether sulfone, filters cut-off molecular weight ranges 35000-65000 dalton.
Adopt the doughnut of above-mentioned specification, its sieveing coeffecient sees the following form 1:

| Molecule title | Sieveing coeffecient |
| Carbamide | 1 |
| Creatinine | 1 |
| β2-microglobulin | 0.85～0.95 |
| Myoglobin | 0.83～0.93 |
| α 1 microglobulin | 0.1～0.2 |
| Albumin | 0～0.02 |
Heart failure ultrafiltration need to adopt little membrane area, high osmosis, high filtrable hemoconcentrator.Correct fluid retention and only need to remove unnecessary sodium and water in body, do not need to remove toxin and metabolite.Not only large membrane area there is no need, also can reduce blood compatibility, increase Operative risk.From table 1, adopt this doughnut can realize the holding back completely of carbamide and creatinine, to albuminous rejection also more than 98%, in addition, β2-microglobulin and Myoglobin also have higher rejection, other composition outflow in can effectively anti-Hemostatic Oral Liquid.
Heart failure is the final Common end of many cardiovascular disease such as coronary heart disease, myocardial infarction, cardiomyopathy, hypertension, and when for above-mentioned disease, by ultrafiltration, remove the effect that sodium unnecessary in blood and water only can play the incidence probability that reduces heart rate exhaustion, but can not using this only resource as treatment.
