  • Publication number: 20230310706
    Abstract: A raw amniotic membrane placed in a processing tank (10) is continuously heated by a far-IR heater (14) provided in the processing tank (10). During a decompression operation in which the interior of the processing tank (10) is placed in a decompressed state, and a recompression operation in which the pressure in the decompressed interior of the processing tank (10) is raised slightly toward atmospheric pressure, the raw amniotic membrane is dried while the water molecules present therein are subjected to energy via microwave irradiation from a microwave irradiation device (30) provided in the processing tank (10). By repeating this multiple times, the amniotic membrane is dried while cells and tissue structures are maintained.

  • Publication number: 20230293766
    Abstract: The present invention addresses the problem of providing a wound contact member (or “contact layer”) that directly promotes wound healing when continuously performing negative pressure wound therapy (NPWT). As a solution, there is provided dry amniotic membrane manufactured by a specified drying process, that is, raw amniotic membrane placed inside a processing tank (10) is continuously heated using an infrared heater (14) provided inside the processing tank (10) while performing a depressurization operation that places the processing tank in a depressurized state and irradiation of the raw amniotic membrane with microwaves from a microwave generating device (30) provided inside the processing tank (10) to apply energy to water molecules present inside the amniotic membrane and cause drying during a pressure recovery operation that slightly raises the pressure inside the depressurized processing tank (10) toward atmospheric pressure.

  • Publication number: 20230293767
    Abstract: The present invention addresses the problem of providing a material as a scaffold used to prevent poor skin grafting when there is a defect in the perichondrium or periosteum or a defect in subcutaneous tissue. As a solution, there is provided a dry amniotic membrane manufactured according to a specific drying process. In more detail, a raw amniotic membrane placed in a processing tank (10) is continuously heated by a far-infrared heater (14) provided inside the processing tank (10), while performing a decompression operation where the interior of the processing tank (10) is placed in a decompressed state and irradiation of the raw amniotic membrane with microwaves from a microwave generating device (30) provided inside the processing tank (10) to apply energy to water molecules present inside the amniotic membrane and cause drying during a pressure recovery operation that slightly raises the pressure inside the depressurized processing tank (10) toward atmospheric pressure.

  • Patent number: 8932641
    Abstract: The present invention provides a dried amnion which is dried with maintaining tissues of a raw amnion and can be easily stored for a prolonged period of time. An amnion which is dried with maintaining cells and tissues of a raw amnion can be produced by repeating a pressure-reducing operation and a pressure-recovery operation several times, the pressure-reducing operation comprising continuously heating a raw amnion placed in a treatment vessel by a far-infrared heater provided in the treatment vessel and reducing the pressure of the inside of the treatment vessel, and the pressure-recovery operation comprising recovering the reduced pressure of the inside of the treatment vessel with heating the amnion by microwaves irradiated from a microwave heating apparatus provided outside of the treatment vessel, and the amnion is characterized by retaining basement membranes and connective tissues which are constituents of the raw amnion.

  • Patent number: 8414929
    Abstract: The dried amniotic membrane is produced by drying a fresh amniotic membrane, which envelopes an embryo of an animal including human, and can be used as a substitute membrane for a membrane tissue in a living body; the dried amniotic membrane is dehydrated and dried so that the dried amniotic membrane can be stored in a dry air in a sterile state; when hydrated again by immersing in water or a buffer solution, the amniotic membrane still has an epithelial cell, a basement membrane and a connective tissue which constitute the fresh amniotic membrane. The dried amniotic membrane is useful as a medical substitute membrane for a membrane tissue in a living body such as a dura mater, a meninx, a pericardium, a pleura and a peritoneum.

  • Publication number: 20100098743
    Abstract: An object is to overcome the disadvantages of a conventional lyophilized amniotic membrane or the like which causes damages in a cell membrane or an amniotic membrane tissue and is therefore not suitable for use as a substitute membrane for a membrane tissue in a living body, and to provide a novel medical substitute membrane composed of a dried amniotic membrane, which can be used as a substitute membrane for a membrane tissue in a living body. The dried amniotic membrane is produced by drying a fresh amniotic membrane, which envelopes an embryo of an animal including human, and can be used as a substitute membrane for a membrane tissue in a living body; the dried amniotic membrane is dehydrated and dried so that the dried amniotic membrane can be stored in a dry air in a sterile state; when hydrated again by immersing in water or a buffer solution, the amniotic membrane still has an epithelial cell, a basement membrane and a connective tissue which constitute the fresh amniotic membrane.

  • Patent number: 6826693
    Abstract: When an information access request is made from a terminal for personal use via a computer network, a terminal information receiving section of an information transmission apparatus extracts terminal information contained in the request. A personal information collating section extracts personal information relevant to that person from personal information accumulated in a database. The information relevant to that person is collected from the database of an information server section and the like. The collected information is edited in an information editing section into contents suited to the terminal.
