Ultrasound With Electrical Stim Input
NOTE: The stimulator device to be connected to this unit shall comply with IEC 601-1 and IEC 601-
2-10 (general and particular standards) requirements.
The Dynatron 150plus allows you to combine electrical stim therapy with Ultrasound
therapy. The device accepts input from electrotherapy devices through the Stim Input
jack found on the back of the device. This jack accommodates a banana adapter (a
pin-to-banana adapter is attached to one output end of a patient lead).
The following instructions explain how to use the Dynatron 150plus with
Dynatronics’ electrotherapy devices. With this type of treatment, the soundhead acts
as one of the electrodes in a 2-electrode stim treatment, and stim is delivered through
the soundhead. See “Usage Cautions - Combination Treatments” in this manual
before using this option.
1. Plug a patient lead into one channel of the Dynatron electrotherapy device. Use a
single lead with two output connectors.
Place a pin-to-banana adapter on one output end of the lead, then plug that banana
adapter into Stim Input jack on the back of the Dynatron 150plus. NOTE: If you
do not have a pin-to banana adapter, contact Dynatronics to order.
Attach the other lead output to an electrode (use an electrode that you normally
use with your Dynatron electrotherapy device) and place the electrode in the
desired location on the patient’s body. The electrode should be placed slightly
outside the area where the Ultrasound will be delivered to allow full movement of
the soundhead over the treatment area. Remember the soundhead delivers Stim
as well as Ultrasound during the treatment, and therefore, the soundhead acts as
the second electrode. Consider this when you determine where to place the
electrode and the soundhead on the patient.
2. Set up an Ultrasound treatment with the Dynatron 150plus. Do not press START.
3. Set up the Stim treatment for the appropriate channel on the Dynatron
electrotherapy device. Use a very low stim intensity for this type of treatment.
4. START the treatments at both devices.
During the treatment, the Stim current is delivered through the soundhead and will
pass between the soundhead and the electrode which was placed on the patient. At
the same time ultrasonic waves are introduced into patient tissue through the
soundhead. Avoid touching the electrode with the soundhead during the treatment,
and keep the Stim intensity low.
