Abstract：Objective A portable continuous blood purification machine which can work under swing,bumping,vibrating,and other special circumstances was developed.The replacement fluid flow control accuracy,dehydration accuracy,the safety and effectiveness was tested and verified by a variety of verification tests.Methods Special performance tests,applications tests on ambulance and marine were carried out to give a comprehensive evaluation of the portable continuous blood purification machines.Results The machine could work under swing,bumping and vibrating and such complex circumstance with high precision measurement.The monitoring system was sensitive and could give an accurate alarm to ensure the safety of the treatment.Renal function indicators and electrolytes indicators were significantly improved after treatment.After treatment,creatinine,urea nitrogen,carbon dioxide combining power,potassium of test dogs improved significantly [the marine environment test ( 55.6 ± 21.2) μmol/L vs (93.0 ±24.4) μmol/L,(4.5 ±0.9)mmol/L vs (9.4 ±3.3)mmol/L,(23.1 ±3.1)mmol/L vs (21.4 ±4.2) mmol/L,(3.6 ±0.5) mmol/L vs (4.7 ± 0.3 ) mmol/L,respectively; ambulance test were(43.3 ± 22.2) μmol/L vs (96.2 ±27.2)μnol/L,(3.7 ± 1.3)mmol/L vs (7.6 ±2.6)mmol/L,(23.3 ±3.2)mmol/L vs (20.2 ± 4.2) mmol/L,(3.4 ± 0.6) mmol/L vs (4.8 ± 0.4) mmol/L t,respectively].Conclusions Portable continuous blood purification machines can be used normally on boat,on ambulance and under other swing,bumping environment to achieve the desired therapeutic prrposes.It also has advantages of a strong environmental adaptability for a wide range of areas and small in size.
