JOURNAL RESTRICTED ACCESSExtracorporeal membrane oxygenation (ECMO) is a system of pump and artificial lung for cardiopulmonary supports, and the number of ECMO cases has increased year by year. Some reports have revealed the impact of ECMO for severe respiratory failure on favorable outcome, but its real benefits are still under investigation. Developing more sophisticated devices and making highly specialized teams of experts with ECMO are future challenges.View full abstractDownload PDF (895K) -

JOURNAL RESTRICTED ACCESSA membrane oxygenator is commonly used open–heart surgery. In recent year, it is increasingly used as respiratory support to patients with severe respiratory, cardiac or combined cardiopulmonary failure. This respiratory support takes range from several days to several weeks, so the membrane oxygenator require long–term safety and long–term durability. Therefore, we are developing a silicone small–diameter hollow fiber and an artificial lung using it. This membrane has high permeability and no plasma leak, so this membrane oxygenator is considered applicable to long-term lung support.View full abstractDownload PDF (793K) -

JOURNAL RESTRICTED ACCESSWhen material contacts to blood, a plasma protein absorb and a platelet adhere on the surface which are induced to unexpected thrombus formation. Surface modification and coating technology for hollow fiber of membrane oxygenator are significance to improve the blood compatibility for long–term use. In this review paper, we summarized a useful coating and immobilization method to anti–thrombotic property on the membrane oxygenator. One is immobilization of antithrombotic reagents like heparin and NO gas, the other is a coating of biocompatible polymers which has inhibit a protein adsorption and a platelet adhesion, and the last is formation of endothelialization. For next generation artificial lung of further extend continuous use period, an improvement of coating durability with keeping functions such as antithrombotic is required.View full abstractDownload PDF (1040K) -

JOURNAL RESTRICTED ACCESSWhen developing a membrane oxygenator, flow control with a blood pump is very useful. Its history began with roller pumps used in extracorporeal circulation devices and moved to centrifugal pumps. In recent years, with the long–term use of artificial lungs, the pivot type is changing to non–contact type hydrodynamic bearings. Since its durability is not much different from that of the auxiliary artificial heart, it has device performance for longer–term treatment.View full abstractDownload PDF (709K)

JOURNAL RESTRICTED ACCESSFiltration and separation technology by separation membranes are one of the key technologies because of its energy- saving. They are indispensable for the processes such as gas purifications and environment protections. The evaluation of pore size and quality judgement of the separation membrane are very important because it has been focusing on the research field in the environment and energy. This paper describes the bubble point method, nano palm porosimetry method, and pore size distribution analysis by GCMC method from N2 (77.4K) adsorption isotherm, which are possibility to be standardized methods in a non-destructive state of separation membranes including nanopores. The membrane structure can be quantitatively investigated by taking advantage of these results.View full abstractDownload PDF (985K)
