TwinStim Digital TENS & EMS Unit

The Twin Stim 2nd edition is an exact combination of our TENS 7000 and EMS 7500, which gives the user the choice of 5 modes of TENS and 2 Modes of EMS. This is the unit that the consumer will buy if given the choice! Twin Stim's features include, Dual Channel, 7 modes, Timer, Patient Compliance Meter, New Stronger 100mA output, safety amplitude cover, sturdy metal belt clip, rubber side railings for maximum handling.

Detailed Description:

Channels: Dual Channel, isolated between channels

Pulse Amplitude: Adjustable, 0-100 mA peak into 500 ohm load each channel.

Voltage: 0 - 50V (Load: 500 ohm)

Pulse Rate: Adjustable, from 2 to 150 Hz, 1 Hz/step

Pulse Width: Adjustable, from 50 to 300 microseconds, 10uS/step

Wave Form: Asymmetrical Bi-Phasic Square Pulse

On Time: Adjustable, 2~90 seconds , 1 Sec./ step

Off Time: Adjustable, 2~90 seconds , 1 Sec./ step

Ramp Time: Adjustable, 1~8 seconds, 1 Sec./ step, The "On" time will increase and decrease in the setting value.

3 EMS Modes: Constant ,Synchronous, Alternate

Constant stimulation based on setting value. Only pulse width, pulse rate and timer are adjustable in this mode. "Constant" is equal to the "Normal" mode of a TENS unit.

Synchronous: Stimulation of both channels occurs synchronously. The "ON" time including "Ramp Up" and "Ramp Down" time. Therefore, the setting of ON Time should be no less than two times of the "Ramp" time in this mode. ON TIME � ƒnRamp up + Ramp down

Alternate: The stimulation of the CH2 will occur after the 1st contraction of CH1 is completed. In this mode, the setting of ON Time should be no less than two times of the "Ramp" time. The OFF Time should be equal or more than the ON Time. ON TIME � ƒnRamp up + Ramp down OFF TIME � ƒnON.

5 Modes: B(Burst), N(Normal), M(Modulation), SD1(Strength Duration), SD2

Burst Mode: Burst rate: Adjustable, 0-5 MilliSeconds; 5Hz; Pulse width adjustable, 50~300uS; Frequency fixed = 100 Hz

Normal Mode: The pulse rate and pulse width are adjustable. It generates continuous stimulation based on the setting value.

Modulation mode is a combination of pulse rate and pulse width modulation. The pulse rate and width are automatically varied in a cycle pattern. The pulse width is decreased by 50% from its original setting in 0.5 second, then the pulse rate is decreased by 50% from its original setting in 0.5 second. Total cycle time is 1 second. In this mode, pulse rate(2-150Hz) and pulse width(50-300 MilliSeconds) are fully adjustable.

The SD1(Strength-Duration) mode consists of automatic modulation intensity and pulse width in 40% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 40% while the pulse width is increased by 40% in 5 seconds. In the next 5 seconds, the intensity is increased by 40% while the pulse width is decreased by 40%. Total cycle time is 10 seconds. Pulse rate(from 2~150Hz) and pulse width (from 50~300 MilliSeconds) are fully adjustable.

The SD2(Strength-Duration) mode consists of automatic modulation intensity and pulse width in 70% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 70% while the pulse width is increased by 70% in 5 seconds. In the next 5 seconds, the intensity is increased by 70% while the pulse width is decreased by 70%. Total cycle time is 10 seconds. Pulse rate(from 2~150Hz) and pulse width (from 50~300 MilliSeconds) are fully adjustable.

Patient Compliance Meter: This unit can store 60 sets of operation records. Total recorded time is 999 hours.

Timer: Adjustable, from 5 to 60 minutes or Continuous. Adjustable in 5 minutes each step. Treatment time countdown automatically.
