Chapter 2. Product
2.1 Introduction of ARTUS-903K
Thank you for purchasing ARTUS-903K.
ARTUS-903K is a rehabilitative exercise equipment (Continuous Passive Motion Machine)
that recovers the lost function of knee joint quickly through the continuous passive motion for
patient who cannot exercise by themselves. It can also be adjusted to an upper and lower
angle limits and also it is available to program 5 steps exercising speed. Acceleration mode
allows the exercise speed up to 2 steps faster than previously programmed speed.
It also provide a caster to move product easily.
Hand Controller(H/C) which is adopting 3.5 inch screen and touch is easy to operate and it
provides the information of progressing and programing exercise on screen.
2.2 Operation
If it is left untreated after the knee joint surgery, it may cause problems such as limited range
of motion and muscle contraction. And applying too much load to the knee joint without
rehabilitation may worsen the condition of the surgical area. So it is necessary to exercise
properly for the quick recovery of surgical area. ARTUS-903K is the rehabilitation equipment
to recover the function of knee joint quickly through continuous passive movement.
Range of motion is different depending on the exercise mode and exercising ROM has to be
programmed according to the condition of patient.
Please exercise at a slow speed at first, and then do exercise higher speed and wider angle
after becoming familiar with the product. Exercise with a large range of motion from the
beginning could cause secondary damage to the patient's surgical site.
