Airpulse PK™ - The Automatic Wheelchair Cushion System

The patented Airpulse PK is an automatic pressure relieving device that ensures adequate pressure relief and blood flow. Alternate cells of the cushion are automatically inflated and deflated to the desired firmness on an adjustable timed cycle. This action changes pressure contact points and stimulates circulation to the compressed tissue. Circulation is maintained to all areas of the posterior so the primary cause of skin breakdown is eliminated.

Each and every Airpulse PK wheelchair cushion system is custom made to order to address the client's specific needs. We have taken on many challenging situations with remarkable results. Clinical case results and customer feedback have proven this product to be effective and doctors frequently recommend the Airpulse PK for use by their patients.

Three Airpulse PK Models

1. Standard Battery Model: powered from its own rechargeable battery source, it will operate for up to 40 continuous hours per charge.
   
   
2. Power Chair Model: powered from the 24-volt power chair batteries only.
   
   
3. Hybrid Model: powered from either the 24-volt power chair battery or its own battery source with the flip of a switch.

The System

The Airpulse PK wheelchair cushion system is preprogrammed and ready to operate when delivered.  The system includes the custom made cushion, cushion cover, controller with cover, battery charger (if applicable), and a one year warranty. See Product Diagram PDF for details.

The Cushion

The Airpulse PK cushion is made of soft but durable Neoprene (no latex) and has a series of air cells. The cells are shaped to fit the contours of the body for comfort and support. They are also reinforced with internal air bladders to ensure long service life. (See Durability Test Results) The two ischial air cells are attached to the cushion base with Velcro enabling them to be easily repositioned if needed.  Alternating air cells are capable of being inflated and deflated at different pressure levels and for varying times for maximum pressure relief where and when you want.

Because every Airpulse PK wheelchair cushion system is custom made, the cushion can be built to whatever size works best for the client's needs.  In other words, no standard sizes, but rather the correct size.  The Airpulse PK cushion can support weights in excess of 400 pounds and bariatric sizes can be made.  Cushion sizes larger than 22" wide or 22" deep have an additional fee.

If the client has a current pressure sore, we may customize the cushion with a convertible cell so there will be virtually zero upward pressure directly under the sore until complete healing is achieved (see Pressure Maps). Once the sore is healed, the cell is integrated back into normal operation in just seconds.

Even with the specialization involved in custom building every system, the product is typically built and shipped within a few days of receipt of order.

The Controller

The control module of the Airpulse PK provides the mechanism to operate the cushion's unique air cell configurations.  The controller contains the micro-processor, control panel, air pump and battery (if applicable).  It is portable, quiet, weighs less than two pounds and the easy-mount cover can be fastened to the armrest, back, or other parts of the chair.  Depending on the model, the controller is powered either by an internal battery or directly from the powerchair batteries. 

The controller gives the user or caregiver a wide range of firmness and cycle time settings, and adjustments can be made with the touch of a button - making it fully adjustable to adapt to the client's future needs.  The two sets of air cells can be set to completely different inflation/deflation cycle times to address pressure relief needs for different posterior locations.

Optional Accessories

All Airpulse PK wheelchair cushion systems include customized cushion with stretch cover, pre-programmed controller with cover, battery charger with the Battery or Hybrid Models, and a one year manufacturer’s warranty. Aquila does offer the following optional accessories:

Deluxe Remote Control
The Airpulse PK system can be completely operated with the use of the Deluxe Remote Control with LCD display. This remote eliminates the need to access the control box to operate or change settings. Although the Airpulse PK controller is small and lightweight, it might make sense for some to store or mount the controller out of the way or out of site. The remote control easily connects to the controller with a coil cord and includes all of the same functions as the control box itself including power switch, cycle time selections and firmness settings. The Deluxe remote also has a built in low pressure and low battery audio alert. The Deluxe Remote Control is moisture resistant, small (2.5" wide x 5" long) and can easily be mounted on any part of the chair with the convenient Velcro strap. The LCD screen on the remote lights up when the system is turned on.

Mini Remote Control
The Mini Remote Control (1.5" wide x 2" long) is smaller than the Deluxe Remote and offers only the basic functions of power switch and visual low pressure alert system.

Moisture Control Unit
The Moisture Control Unit or MCU is an add-on unit that forces a high-volume of air between the cells of the cushion to help keep the posterior cool and dry. The basic Airpulse PK cushion system already has some ventilation as the exhausted air during the deflation cycle is funneled between the air cells. However, the MCU greatly enhances the moisture control by providing the additional forced air ventilation, keeping skin dry and helping to prevent skin maceration. The MCU connects to the front of the cushion and operates by use of a wired mini remote that can be mounted anywhere on the chair. The MCU can be turned on/off as needed without interrupting normal operation of the cushion system.

Incontinence Cover
Every Aquila cushion system comes with a stretchable, breathable and washable cover for the cushion. However, incontinence covers in any size are also available.

Extended Warranty
The Airpulse PK cushion system comes with a one-year manufacturer’s warranty. A one-year warranty extension can be purchased either at the time of the initial order or anytime within one year of the original system purchase. Both the original and extended warranties cover all parts and labor.

Customized Solution

The Airpulse PK is not an “off the shelf” product. Each Airpulse PK cushion system we build is tailored to match the specific needs of the individual client. We have years of experience in designing the most appropriate systems for difficult seating situations. We gather information on the client such as weight, location of any existing and past history of any pressure sores, the type of chair used by the client, and any special situations such as compensating for pelvic lean, high level amputations, MS patient with severe pelvic obliquities and patients with acute Stage IV pressure sores. Then we program the controller and build the cushion for optimal effectiveness. The Airpulse PK system has also helped reduce recovery time for post flap surgery patients. See our Customization Scenarios for examples.

Safety

The Airpulse PK has a low pressure audible and visual alert. The cushion will not deflate if the battery should become fully discharged or the unit is turned off. The cells also have foam insert to guard against bottoming out in the unlikely event that the cushion should become damaged and lose air.

System Features

• Up to nine cushion pressure selections for desired firmness
• Adjustable cycle time settings from one to nine minutes
• Light-weight control module weighing less than 2 lbs.
• Run time of up to 40 hours per battery charge
