摘要： A transdermal drug administration device which comprises a patch that is provided with: a donor gel in which a medical agent is sealed; a reference gel; a first electrode that is connected to the donor gel; and a second electrode that is connected to the reference gel. When the patch is applied to the skin, a direct current is applied between the first electrode and the second electrode at a predetermined cycle and an alternating current is applied between the first electrode and the second electrode during the periods when a direct current is not applied, thereby obtaining the capacitance. The application state of the patch is determined based on the thus-obtained capacitance.

摘要： A ventricular assist system includes a controller supplying a DC voltage or an AC voltage, and electromagnets adapted to be adhered to an infarct portion of a heart at the time of embedding a pump. After embedding the system, cells enclosed in capsules are released into the surroundings of the infarct portion by use of a catheter. The capsules are magnetic so that they can be concentrated onto the infarct portion by magnetic fields of the electromagnets, and are broken in the vicinity of the infarct portion, whereby cells effective for regeneration of cardiac muscles can be conveyed to the infarct portion in a noninvasive manner after the embedding of the ventricular assist system.

摘要： A sensorless magnetic bearing type blood pump apparatus includes a blood pump and a control mechanism. The blood pump has electromagnets for rotating a rotating body in a non-contact condition, and a hydrodynamic bearing section for rotating the rotating body in a non-contact condition when operation of the electromagnets is stopped. The apparatus is devoid of any sensors for determining the position of the rotating body. The control mechanism includes a pulse width modulation type electromagnet driving unit, a carrier component measuring unit for measuring carrier components of voltage and current in the driving unit, a modulation factor calculating unit which calculates a modulation factor using the carrier wave data, and a bearing mode changing-over mechanism for effecting change-over from the magnetic bearing mode to the hydrodynamic bearing mode when the calculated modulation factor is outside a predetermined range and for returning to the magnetic bearing mode after the change-over.
