Attaching A Patient To The Unweighing System - biodex 945-480 Installation & Operation Manual

CONTENTS
Adjustment: The shoulder straps can be lengthened or shortened using the end of the
strap located near the seat belt buckle. The cross bar is used to adjust for patient height.
NOTE: Be aware of incontinence concerns. Use of the unweighing harness can put pressure on the
patient's abdominal area, including the bladder. Should a harness become soiled, it can be hand-washed
in a sanitizing detergent, then air-dried.

ATTACHING A PATIENT TO THE UNWEIGHING SYSTEM

(See Figures 9 - 13.)
NOTE: The Offset Unweighing System is designed to meet the hospital
requirements of an eight-time load rating. The device is rated for use with patients
to provide up to 180 pounds (82 kg) of unweighing load, (50% unweighing of a
360-lb patient.)
NOTE: Patient set-up should be conducted over the desired walking surface (i.e,
treadmill or floor,) as moving from the floor to the treadmill will require the set up
procedure be repeated.
1. Turn on the display on the right side of the unit. Toggle ON pounds/
kilograms and then use the round knob to zero out the display.
NOTE: The display shuts OFF automatically after 30 minutes. To turn the
display back ON, press the <ON> button.
2. Use Handle #2 on the right side of the unit to dial in the approximate amount of weight to
remove from the patient as displayed on the color-coded unloading scale.
3. Use Handle #1 on the left side of the unit to lower the patient harness bar so that it rests
approximately 2 inches above the patient's head.
4. With the harness adjusted to the patient for a tight, comfortable fit, slip the large harness rings
onto the safety harness clips at the end of the support rope. To do this, pull on the red tabs to
release the clips. Slide the harness rings onto the clips and then lock the clips back in place.
5. Crank Handle #1 on the left side of the unit to raise the patient harness until the red stop
indicator bar on the front right side of the top assembly is at the approximate middle of the
scale. This mid-scale position for the stop indicator must be maintained.
6. Check the display to see how much weight has been lifted from the patient. Use Handle #2
on the right side of the unit to fine-adjust the weight removed until the display shows the
desired level. Ensure that the red stop indicator is still in the middle of the scale.
7. Ensure the patient is comfortable and that the vest is properly fitted. Be sure the shoulder
straps do not rub against the patient's ears. Make sure the bar does not hit the patient's head.
The Unweighing System is now ready for use.
NOTE: Handle #1 can be used two different ways. Pull out the handle knob and slide it to the inner
position to crank the handle and adjust the crossbar height quickly. Use the outer position to improve
your mechanical advantage when assisting the patient to a standing position.
