## CPC

- A61N 2/02: using magnetic fields produced by coils, including single turn loops or electromagnets (A61N2/12 takes precedence)
- A61N: ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY (measurement of bioelectric currents A61B; surgical instruments, devices or methods for transferring non-mechanical forms of energy to or from the body A61B18/00; anaesthetic apparatus in general A61M; incandescent lamps H01K; infrared radiators for heating H05B)

## Abstract

A magnetic therapeutic apparatus comprising a plurality of magnetic therapeutic units (4A)(4B) including one or more electromagnetic solenoids (17) as magnetic field generating source, and a timer (1) which is disposed between the magnetic therapeutic units (4A)(4B) and an AC power source and controls the operation time of the magnetic therapeutic units (4A)(4B) all at once. The magnetic therapeutic units (4A)(4B) are respectively connected with electric cord wires (5A)(5B) provided with plugs (10A)(10B) at the ends thereof, and the timer (1) is provided with a plurality of plug-in sockets (6A)(6B) which can respectively be connected with the plugs (10A)(10B). The plugs (10A)(10B) of the electric cord wires (5A)(5B) are respectively inserted into the plug-in sockets (10A)(10B), which makes it possible to set the time for respective magnetic therapeutic units (4A)(4B) by one timer (1), so time setting operation for magnetic therapeutic units (4A)(4B) becomes easy.

## Claims

### Claim 1

A magnetic therapeutic apparatus comprising:
a plurality of magnetic therapeutic units each including one or more electromagnetic solenoids for generating magnetic fields:
a timer unit for applying power to said plurality of magnetic therapeutic units during a selectable time period:
each of said plurality of magnetic therapeutic units having an electric cord with a plug at a distal end thereof for connection to said timer unit: and said timer unit having a plurality of sockets for accepting the plugs of the magnetic therapeutic units.

### Claim 2 (depends on 1)

A magnetic therapeutic apparatus according to claim 1 wherein:
each of said plugs have a pair of connecting plates projecting therefrom with planes of said connecting plates substantially perpendicular to each other; and
each of said sockets having a pair of connecting slots disposed with planes thereof substantially perpendicular to each other and positioned for accepting the connecting plates of the plugs whereby when said connecting plates are engaged with said connecting slots dislodgement of said plugs from said sockets by forces parallel to said planes of said connecting plates and sockets is prevented.
