2-0: Description and Features
–
2.1 Product Description
•
The ACS Positioning Chair is designed with both patient and operator in mind. Helping to reduce back injuries, the product is used to position a patient
during patient assessment.
•
The Positioning Chair may be used with the Ven-View Examination Module as part of the Ven-View System, or as a standalone option for other areas
of patient assessment as determined by the healthcare provider.
•
Whether used with or without the Ven-View Examination Module, the Positioning Chair provides hands-free, ergonomically sound patient movement
from a sitting position to supine and everywhere in between.
•
A description of the main Positioning Chair parts are found in section 4 of this User Guide.
– 2.2 Positioning Chair Features
•
While the ACS Positioning Chair is simple to use, the product contains many valuable features for the user.

Positioning Chair Users Guide
• Large Backrest and Footrest
•
Unlike other patient assessment positioning chairs, the ACS Positioning Chair utilizes a large back cushion to accommodate larger patient
size and weight. In fact, the ACS Positioning Chair has been tested for patient load up to 400 lbs.
• Footrest Adjustment to Flat
•
•
The Positioning Chair has the ability to be affixed in a completely flat (lying) position. As shown in the figure below, simply pull on the Tbar handle labeled “Pull to Lay Flat” to position the chair.
When the T-bar is pulled back, this will allow the main “leg” to be released from its holding notch and position in a flat orientation. Support legs will
comedown from under the footrest when in this position. ALWAYS MAKE SURE THAT MAIN LEG “PINS” ARE NOTCHED BEFORE LOADING
PATIENT! FOOT REST SHOULD NEVER BE USED TO SUPPORT A PERSON’S WEIGHT! DO NOT SIT ON THE FOOT REST AT ANY TIME!

• Footrest Adjustment Based on Patient Length
•
A unique product feature is the ability to adjust the footrest to accomodate various patient height. As shown in the figure below, once the
product is moved to the flat position, pull on the T-bar handle labeled “Pull to Adjust Foot Rest Position.” The footrest will slide toward and
away from the user for perfect patient positioning. To minimize injury, keep hands away from footrest adjustment mechanism.
• Complete Patient Access
•
The ACS Positioning Chair has been designed to provide full access to the lower extremities (under legs, calves, ankle region) which is often
required for complete patient assessment.

• Hands Free Control
•
Movements for the ACS Positioning Chair are done using the provided foot control. Please note that there are two directional modes for the
foot control: Lay Down and Sit Up.
•
The Lay Down position takes the product from a sitting position to a laying down or flat (supine) position. This motion leans back the back
cushion and raises the foot rest.
•
The Sit-Up position takes the product from the Lay Down position to an upright or sitting position. This motion raises the back rest cushion
and lowers the foot rest.
•
When moving the Positioning Chair from the sitting to supine position (Lay Down) and back to Sit Up, ensure the following:
–
–
All hands, fingers, head and feet are cleared from product movements.
The patient is situated on the Positioning Chair and is warned about movement and direction before product moves from a stopped position.
•
PLEASE CONSIDER ALL SAFETY LABELING before operating this product. The following labels are used on the Positioning Chair and
should be referenced before operation to ensure safety to user and patient.
•
When moving the Positioning Chair, ensure feet are cleared from the wheels to avoid crushing. The label below provides a warning on all
product wheel/caster areas:

•
The main product “leg” which resides under the seat cushion while in the upright position will contact the area under the seat cushion.
DO NOT PLACE HANDS OR FINGERS UNDER THE SEAT CUSHION AT ANY TIME to avoid pinching and digits being
crushed! The label below resides on the product “leg” area and shows where this pinch/crushing location is .
•
In the same location under the seat cushion is a sensing bumper. If hands and fingers happen to be located under the seat cushion when
the product moves from a sitting to lying down position, the sensing edge will shut off the power supply (and motor) to the actuator,
stopping chair movement. To reset the sensing edge, power OFF the product and turn the power back ON. The power supply will
power on and the product is ready to use.
•
The figure below shows the sensing edge below the seat cushion and the potential pinch point that should be avoided at all times by
both user and loaded patient.

– 4-2 Patient Loading
Version: 001
PHLB5004
•
Load the patient onto the Positioning Chair seat cushion with the chair position upright. NEVER LOAD OR UNLOAD PATIENT IN THE
SUPINE (LYING) POSITION.
•
After checking to ensure the footrest is securely placed fllush with the ground, the patient may load by either stepping on the footrest to sit,
or straddling the main leg of the chair and turning backwards.
•
The patient’s feet should be spaced evenly on the footrest and should not be positioned at the near or far end of the footrest pad.
•
Instruct the patient to slide clear back on the seat cushion to avoid falling forward.
Advanze Cardio Systems, Inc.

Positioning Chair Users Guide
•
Instruct the patient to ALWAYS PLACE BOTH HANDS SECURELY ON THE HANDRAILS. To avoid pinch points and crushing
areas, always have both hands remain on the handrails.
•
Always provide a verbal notice to the patient before moving the Positioning Chair in either direction. This is especially important when
moving the chair from a lying position (supine) to upright as the chair moves quickly (4.5 seconds or less travel) when moving upright.
– 4-3 Patient Unloading
Version: 001
PHLB5004
•
When unloading the patient from the Positioning Chair, NEVER LOAD OR UNLOAD PATIENT IN THE SUPINE (LYING)
POSITION.
•
Always ensure that the footrest is securely placed flush with the ground. The footrest is properly grounded when the pad under the foot
rest is secure and the footrest does not “give” or move when weight is applied to any edge or corner of the footrest cushion.

•
Disinfect the Positioning Chair after each use. Following each examination, the seat and back cushions should be wiped with either a
70% IPA 30% water mixture or Theracide ® Plus cleaner before re-use. Cleaned areas should be allowed to dry for 15 minutes.
•
In addition, the Permablok3® cushion material on the footrest and seat and back cushions may be cleaned with a1:1 mix of ammonia
and water or a 1:4 mix of bleach and water if blood, urine or feces are present. Rinse with clean water and dry.

• Positioning Chair Will Not Power Up When Foot Rest Is Lowered
•
Version: 001
PHLB5004
Possible causes/Solutions:
–
The ACS Positioning Chair is designed for patient and user safety. One safety function designed into the Chair are limit switches in the knee
gatch area. When the foot rest is in the supine position (laying down flat), or in any position other than when the pins are found in the notch
area, power to the Chair will be cut-off.
–
Solution: To re-activate electricity to the Chair, re-position the foot rest pins into the main leg notch area by using the T-handle labeled “Pull To
Lay Flat”.
–
The picture below (left) shows the foot rest in the supine (laying down flat) position. The limit switch magnets are separated, cutting power
from the Positioning Chair. As shown in the picture below (right), the foot rest must be raised with pins secured in the notch area for power to
be restored to the Positioning Chair.

• Positioning Chair Movement Seems to “Drift” or Not Stop In Same Position
•
Possible causes/Solutions:
–
Limit Switches and/or potentiometer may require adjustment.
–
Solution: ACS does not recommend adjustment of the limit switches to compensate for drifting or misalignment of chair positions. The
Company recommends the user to contact Advanze Cardio Systems and schedule a service call. For reference, the limit switches are found
under the left arm rest handle and the potentiometer under the right arm rest.
