  • Patent number: 11779690
    Abstract: Hollow fiber membranes in an oxygenator for an extracorporeal blood circulator are coated with an antithrombotic polymeric material. The porous hollow fiber membranes for gas exchange have outer surfaces, inner surfaces forming lumens, opening portions through which the outer surfaces communicate with the inner surfaces in a housing. A blood flow path is outside of the hollow fiber membrane bundle in the housing, between a blood inlet port and a blood outlet port. The coating is obtained by filling the blood flow path with a colloidal solution containing an antithrombotic polymeric compound, and moving the colloid solution between the blood inlet port and the blood outlet port for a time that coats a predetermined amount of antithrombotic polymeric compound on the outer surfaces of the hollow fiber membranes. Other surfaces within the oxygenator contacting the blood flow likewise receive the coating.

    Abstract: A method is disclosed for producing an artificial lung including a plurality of porous hollow fiber membranes for gas exchange which have an outer surface, an inner surface forming a lumen, and an opening portion communicating the outer surface with the inner surface. The method includes bringing any of the outer surface and the inner surface into contact with a colloidal solution that contains an antithrombotic high-molecular compound to circulate carbon dioxide gas to a side of the other surface. According to the present disclosure, an artificial lung can be produced in which a coating amount of antithrombotic high-polymer material (an antithrombotic high-molecular compound) on a hollow fiber membrane is increased.

  • Patent number: 9900818
    Abstract: When a representative PS server receives a P-TMSI contained in a PDP context succession request signal from a UE according to a handover communication procedure prescribed in an applicable standard after the UE moves, if the PS server identified with the identification information contained in the received P-TMSI is not its own representative PS server, the representative PS server identifies the PS server identified with the identification information as a PS server that manages a femtocell base station to which the UE belonged before it moved and forwards the PDP context succession request signal to the identified PS server.

  • Patent number: 9860729
    Abstract: AS-B (810) measures a telephone call time from a time point when a telephone call, which is audio-originated by UE (100), starts. When a time obtained by subtracting the telephone call time from a time for which the UE (100) can telephone-call becomes a predetermined time, the AS-B (810) issues a multiplex instruction to FAP (200). When having received the multiplex instruction, the FAP (200) multiplexes a sound, which is based on a sound source file stored in advance, with audio data to be transmitted to the UE (100), and transmits the audio data, with which the sound has been multiplexed, to the UE (100).

  • Publication number: 20170164251
    Abstract: When a mobile terminal currently performing a voice communication or currently initiating a call by use of a VoLTE function moves from an LTE network to 3G femto-network, a GW (100) is connected to an MME (200) disposed on an access network in the LTE network and to an FAP (300) having an IMS-femtocell area as a communication area to be handed over the voice communication or the initiation of the call. When the mobile terminal currently performing the telephone communication or currently initiating the call moves from the communication area of the LTE network to the IMS-femtocell area, a call processing of the mobile terminal is caused to be handed over from the MME (200) to the FAP (300).
