3 General information
3.1 Shortwave diathermy applications
The Auto*Therm
®
395 is a shortwave diathermy device that operates at 27.12 MHz. It provides
traditional shortwave diathermy therapy using condenser and electromagnetic inductive coil fields in
both continuous and pulsed modes of operation. Therefore, it is suited for all diathermy treatments in
both the clinic and the medical practice.
The use of shortwave diathermy for heat therapy has the advantage of penetrating deeper than other
conventional methods, such as hot packs, infrared lights and heat pillows, and even microwave
diathermy.
The heat generated by shortwave diathermy induces a whole range of physiological effects. It relaxes
muscles, tendons and other connective tissues, and increases blood circulation in the treatment area.
When shortwave diathermy is applied in short, high-energy pulses the depth of penetration is
increased, having a particularly positive effect on the blood circulation, while the temperature sensitive
skin hardly feels the heat.
Shortwave diathermy can be applied over a large area of the skin’s surface.
3.2 Unit description
The Auto*Therm 395 has four wheels for easy transportation between treatment rooms. Two of these
wheels have brakes that can be locked to prevent movement during use.
The membrane control panel is mounted on the top of the unit. It is easily cleaned and contains all the
controls and displays for operating the Auto*Therm 395.
The intensity control knob
(17) adjusts the output power via an encoder. The power switch (1)
(ON/OFF) is on the upper left side of the unit. Screw holes for attaching the arms are located on the
rear of the unit
(35) . The sockets for connecting the cables for the condenser (31) and inductive coil
(30) applicators and the detachable mains power supply cable (33) including fuses are also located on
the back of the unit. The ripcord (34) for the patient emergency-0FF switch passes through a bushing
mounted on the back of the unit so that it can be pulled from all directions.
3.3 Arms
The arms are mounted at the rear of the appliance (35) by means of keyhole type connectors (27).
Both arms must be installed to use the condenser applicators that must be used in pairs. The
inductive coil applicators require only one arm to be installed. Both arms can be attached to the
device so that you can change applicators at will. The clinician can safely position the applicators in
widely differing treatment positions because the arm has five locking joints. The arms are made of
high quality flame-resistant plastic material so that they can be used to guide and hold the applicator
cables in order to avoid inadvertent contact between patient and cables.
Refer to the illustration of the arm assembly on page 5 for all the following instructions. With the
exception of the horizontal swing of arm and hinge
(20) of the applicator hoIder (19) , all hinges can be
adjusted by the user as the treatment demands.
The lock knob (26) on the lower rotating hinge (25) locks the whole arm in position, even when the
arm is maximally extended. The other main hinges (21; 23) that control the length and height of the
arm can be adjusted after the appropriate knobs have been loosened. To do this, it is practical to
support the arm above the hinge that has been loosened
(20) or (21) .
The shaft of condenser or inductive coil applicators is inserted into the aperture of applicator holder
(19) until the slide (18) snaps shut.
