The present invention provides an apparatus for applying electrical stimulation to cells in a liquid culture medium without using electrodes immersed in the liquid culture medium. This apparatus is an electrical stimulation apparatus A for electrically stimulating cells in a liquid culture medium (). A liquid culture medium vessel () includes: a ring-shaped recess () for holding the liquid culture medium (); and a through hole () formed within the ring-shaped recess (). A magnetic core () is made of a magnetic material and disposed such that a portion thereof is inserted through the through hole () of the liquid culture medium vessel (). An excitation coil () is wound around the magnetic core (). A coil power supply () supplies a varying current to the excitation coil ().

Apparatus and method for non-contact electrical stimulation of cells in liquid culture medium

A smaller-sized, more lightweight, and power-saving successive magnetic pulse device is provided. A discharging circuit section K is configured by connecting, in series in a loop, a magnetic therapy pulse coilconfigured to generate an eddy current in a target part, a charging/discharging capacitor, and a switching semiconductor elementconfigured to supply a discharge current from the charging/discharging capacitorto the pulse coil. A step-up transformerincludes a primary-side coilconnected to an AC power supplyand a secondary-side coilconnected to input terminalsof a full-wave rectifying circuit. A control unitis connected to a switching semiconductor elementand controls conduction timing of the switching semiconductor element. The full-wave rectifying circuithas output terminalsconnected to both terminals Pand Pof the charging/discharging capacitor, respectively. An inductoris connected between the output terminalof the full-wave rectifying circuitand the terminal Pof the charging/discharging capacitor

Medical successive magnetic pulse generation device

The invention provides magnesium fuel cells which can prevent the self-discharge of negative electrode materials and can produce electricity stably for a long term. A magnesium fuel cell includes a negative electrode material including a magnesium alloy, and an electrolytic solution for eluting magnesium ions from the negative electrode material. The magnesium alloy contains aluminum and calcium. The electrolytic solution is preferably an aqueous sodium chloride solution, an aqueous sodium hydroxide solution, an aqueous sodium hydrogencarbonate solution, an aqueous sodium percarbonate solution, or a mixture including two or more of these solutions.

Magnesium alloy fuel cell
