  • Patent number: 11944731
    Abstract: A dialyzer control apparatus includes a magnetic field generator which is disposed on an outer surface of a dialyzer which removes wastes from a blood flowing therein and generates a magnetic field; and a controller which controls the magnetic field generator to perform a magnetic field stimulation on the blood flowing into the dialyzer. The magnetic field stimulation may be a stimulation related to the improvement of the Rouleaux formation for the red blood cells in the blood.

  • Publication number: 20160000600
    Abstract: An eyeball cooling module includes a cooling device and a heat dissipation unit. The cooling device generates a cooling stimulation to human eyeballs by absorbing heat from a first side in which the human eyeballs are disposed and dissipating heat to a second side opposed to the first side. The heat dissipation unit is disposed at the second side of the cooling device, and dissipates heat from the second side of the cooling device externally. Accordingly, cooling stimulation to eyeballs of a human may be generated to human eyeballs, fatigue of eyes and eyeballs may be relieved at home and eyeball fever may be reduced at hospitals.
