  • Publication number: 20200333328
    Abstract: A biological environment simulating apparatus using rotational force includes a mounting unit on which a cell to be pressurized is mounted, a rotational force application unit configured to apply centripetal force to the mounting unit to make the mounting unit perform a circular movement along a circular path about a predetermined center point and a control unit. The control unit controls the rotational force application unit based on a type of the cell and an appropriate pressure condition matched with the type of the cell so that a pressure satisfying the appropriate pressure condition is applied to the cell.

  • Publication number: 20140257178
    Abstract: A drug infusion pump is provided. The drug infusion pump includes a main body including a drive motor and a processor, and a cartridge module including a pump module and a drug cartridge and detachably provided in the main body. When the cartridge module is fitted in the main body, the pump module and the drug cartridge are accommodated in the main body and the pump module is coupled to the drive motor. The drug infusion pump is configured such that the pump module is coupled with the drive motor when the cartridge module is fitted in the main body. Accordingly, the cartridge may be easily separated and replaced so as to address a problem of a patient's inconvenience in using the drug infusion pump.

  • Patent number: 8815088
    Abstract: According to the present invention, a dialysis fluid pump comprises: a housing having an accommodating space formed therein; a dialysis fluid supply tube and a dialysis fluid recovery tube, at least a portion of each of which is accommodated in the accommodating space; a cam rotatably installed in the accommodating space; a motor for rotating the cam; and a first backflow pressure preventer and a second backflow pressure preventer adapted to be mobile in the accommodating space and be pushed by the cam. The dialysis fluid supply tube is made of a flexible material which can be contracted or relaxed, and one end thereof is connected to a dialysis fluid supply tank and the other end thereof is connected to a hemodialysis filter. The dialysis fluid recovery tube is made of a flexible material which can be contracted or relaxed, and one end thereof is connected to a dialysis fluid recovery tank and the other end thereof connected to the hemodialysis filter.

  • Publication number: 20110139704
    Abstract: A blood dialyzing apparatus includes a blood dialyzing filter for dialyzing blood by using a pressure difference between the blood and a dialysis solution, and a supplying means for supplying the blood and the dialysis solution to the blood dialyzing filter in order to alternately generate a state where a blood pressure is higher than a dialysis solution pressure and a state where the dialysis solution pressure is higher than the blood pressure. The blood dialyzing apparatus dialyzes a large volume of blood in a short period of time without increasing the size of the blood dialyzing filter and simply controls the volume of the dialyzed blood by adjusting the supply pressures of the blood and the dialysis solution.
