KX-3A Spastic Muscle Low-Frequency Therapy DeviceUsage Methods:

1. Alternating stimulation of spastic muscles and antagonistic muscles (for limb spastic paralysis);

2. Alternating stimulation of trunk muscle spasms;

3. Alternating stimulation to enhance bidirectional joint mobility;

4. Electroacupuncture therapy;

5. Unipolar motor point stimulation electrotherapy and acupoint electrotherapy (for distal limbs or small muscles).

KX-3A Spastic Muscle Low-Frequency Therapy Device Main Performance:

(1) Output waveform: Both channel A and B outputs are non-polarized bidirectional asymmetric pulses.

(2) Pulse cycle: Adjustable from 1s to 2s continuously, tolerance ±15%.

(3) Pulse width: Adjustable from 0.1ms to 0.5ms continuously, tolerance ±30%.

(4) Single pulse charge at maximum output: Should be greater than 7μC.

(5) Delay time: Channel B output pulse appears delayed relative to channel A, with delay time T1 adjustable from 0.1s to 1.5s continuously, tolerance ±15%.

(6) Output intensity: Peak pulse current Ip for both channels A and B is adjustable from 0mA to 99mA continuously. Maximum output tolerance ±10%.

(7) Timer settings: Six settings: 5, 10, 12, 20, 25, 30 minutes, tolerance ±5%.

(8) Misadjustment indicator: Activates when pulse cycle is less than or equal to delay time due to improper adjustment.

(9) Maximum output voltage: Peak output voltage should not exceed 500V when output is open-circuited.

(10) Resistance to output short-circuit and open-circuit: The device should withstand open and short circuits without performance degradation.

(11) Output upon power restoration: When output exceeds 10mA (RMS) or 10V (RMS) on a 1kΩ load, the device must not output after power interruption and restoration unless output amplitude is preset to minimum.

(12) Output adjustment and minimum output: Output amplitude should adjust continuously and uniformly, or in discrete increments no greater than 1mA or 1V. Minimum output should not exceed 2% of maximum output.

(13) Output DC component: DC component of output should be zero.
