The specific embodiment
Following with reference to description of drawings one embodiment of the present of invention.Fig. 1 is to use the connection layout of therapeutic apparatus of the treatment electrostatic potential loading device of one embodiment of the invention.Among Fig. 1, label 1 is the potential generator that produces the treatment electrostatic potential, and 1a is the lead-out terminal of this potential generator 1 output positive potential, and 1b is the ground terminal of output earthing potential.
The 3rd, insulation electrotherapy bed, the 4th, this insulation electrotherapy bed conductor inside, the 5th, insulator, the 6th, in adorn high-resistance negative electrode, the 7th, human body, 8a is the lead that is connected described potential generator 1, described insulation electrotherapy bed 3 and described negative electrode 6 with 8b, couples together like that as shown in the figure, treats with being applied to the electric charge that the described conductor 4 of described insulation electrotherapy bed 3 and the voltage between the human body 7 and electrostatic capacitance cause.
Fig. 2 is that the inside of the described potential generator 1 of one embodiment of the invention constitutes the block diagram that is connected with mains supply.Among Fig. 2, the 10th, single-phase 100V mains supply, the 11st, socket has electrode 11a and 11b, and this electrode 11b detects the earth lead side that detects described mains supply by AC earth lead described later, and is connected ground connection with this earth lead.
The inside of potential generator 1 constitutes to be made up of the attaching plug 12 with electrode 12a and 12b, electric fuse 13, circuit switching part 14, leakage current test section 15, ground connection connecting portion 16, control circuit 17, power supply unit 18, output circuit 19 and holding circuit 20 etc., and lead-out terminal 1a by the output positive potential and ground terminal 1b and external mechanical and human body couple together.
The following describes the action of the described potential generator 1 of this formation.
This potential generator 1 is driven by the single-phase mains supply of 100V, and through the output circuit 19 of control circuit 17 controls and the holding circuit 20 outputs DC voltage by power supply 18 rectifications, and conductor 4 and the negative electrode of receiving described insulation electrotherapy bed 3 are treated.
When output set to be selected and negative charge pattern when treating, the earth lead measuring ability action of the mains supply of this potential generator 1.
It is a line of being selected among input line 12a or the 12b by circuit switching part 14 earlier that the earth lead of mains supply detects, and detects leakage current between this selected line and lead-out terminal 1a and the ground terminal 1b with leakage current test section 15 then.
