A Primary Aid in Pressure Ulcer Prevention

LiquiCell is a medical technology that protects skin tissues form being stretched and torn, thereby optimizing blood flow. As a replication of the bursa sac, LiquiCell allows the body to glide or float with an object to significantly reduce and even eliminate shear and friction. LiquiCell is an aid in the prevention of pressure ulcers. No one device or technology will in and of itself prevent pressure ulcers. However, today the wound care community is seeking out preventative solutions to the various risk factors which are the means to the development of pressure ulcers.

blood flow.

Why Ergo21 Lumbar Cushion is a must for Wheelchair and Mobility Scooter

Our research shows that most of the wheelchairs don’t have a good back support.  Now with our Erg21 Lumbar Cushion with the same LiquiCell Technology, the spine is held straight like a letter T. This promotes proper spinal alignment and the Membranes keep the circulation and nutrients flowing along the spine. Wheelchair Cushion and Wheelchair Lumbar Cushion support are most important support you need for your wheelchair or mobility scooter.

  • Deep Rest and Relaxation for the Spine- Enjoy sitting for longer periods of time
  • Liquid Filled Membranes eliminate hot spots when you lean against the Lumbar Support
  • High Resilience Foam, molds and fills in the gaps to support the spine in a natural way without the annoying hump/bump that other Lumbar Cushions have.
  • Liquid-Filled Membranes improve Blood Flow and Circulation by 150%

Available in two sizes. Small Lumbar fits most low back wheelchairs cushion. The Large Lumbar works best in high back scooter type wheelchairs, cars, trucks and recliners. Can be used on sofas as well as executive high back chairs.

Long Term Blood Perfusion When Sitting on Three Different Cushioning Materials”

Goossens, Delft University of Technology, March 2006

Delft University conducted a study to determine the affect of various cushioning materials on blood perfusion (flow) over time. The aim of the study was to compare blood perfusion in the tissue in a live setting as opposed to a laboratory to get a more accurate reflection of real life conditions. The results of the study show that from the initial point of contact to some time later, LiquiCell actually improves blood perfusion by 150%, whereas gel and foam show a decrease in blood perfusion.

Pressure Ulcers: a growing problem

Each year in the US, over 1 million people will develop at least one pressure ulcer, at a total treatment cost of over $55 billion.

Aging population – in the next 25 years – 60% over 65

Limited care provider staffing – younger people are not opting for careers in healthcare (particularly nursing)

Medicare reimbursement reform – HAC (Never Events)

Cost – average per patient PU treatment cost: $55,000 – $70,000+

liquicell explanation

Mortality rate – at hospitals: 23%-37% of afflicted PU patients (60K/yr).

Quality of Life – average hospital stay increases by 5 fold.

tstimg-cushionsport-1“I am a sports fan and the seats at the stadium are hard and uncomfortable. With this seat cushion it’s a pleasure to enjoy my favorite games without butt-ache.” – M. Morris

“I can now sit longer and more comfortable on my wheelchair without any soreness. It has a nice carry handle and I also often use it on my bench in the backyard.” – Nirmal .K

“I really like the lumbar cushion in the car. I feel like it helps prevent me from rolling my shoulders forward because I have something to push my shoulders into. I have always thought car seats are not designed very well, and kind of encourage you to have bad posture. I feel like the lumbar cushion helps get me in that neutral position.”

*****5.0 out of 5 stars. The nurses aides that get me in and out of bed are amazed how fast my bottom healed…

Size: Large -18″ x 17″ x 2″|Verified Purchase

This cushion provides the most comfort and prevention of bed sores of any cushion I have used during twenty-five years of wheelchair confinement. At first blush the price seemed high, but so did the reviews, and I was desperate to find something that would provide relief from bed sores and further aggravation of skin breakdown. I don’t pretend to understand how it works – it just does. The nurses aides that get me in and out of bed are amazed how fast my bottom healed. The cushion and company have certainly earned five stars or more.

*****Best one ever, I’ve tried many! – Available in four sizes!

Ergo21 Coccyx Cushion
Size: Large – 18″ x 17″ x 2″| Verified Purchase
I purchased this for my dad’s wheelchair and in the 3 weeks he’s been using it, his coccyx pressure sore has almost completely healed. I can hear when he transfers to his wheelchair that it doesn’t hurt him as much when he sits into the cushion. I’ve purchased several other cushions, including one recommended by his physical therapist, and none did much to relieve the concentrated pressure or pain. I’m purchasing another one to use for his power chair.

*****We have finally arrived at the best cushion for my husband’s wheelchair

After 3 years of switching cushions to find a “better fit”; we have finally arrived at the best cushion for my husband’s wheelchair. The Sports cushions were exchanged until we had the correct fit and non-slip cover. Also, the lumbar cushion is great for longer car rides..and I bought another for myself. This company was wonderful with their personalized customer service and follow-up. I would highly recommend these products.

*****Very Good Cushion for Sciatica sufferer

I had an accident and fractured my hip. After surgery with total hip replacement, 8 weeks of FT and cortisone shots, I continued with pain on my sciatic nerve. Note that it is not cause by back problems but more like by muscles pinging on the nerve and or scar tissue. Sitting on soft or bucket like seats has always been a pain. After testing two different times of seats I settled on Ergo21 LiquiCell Cushion and bought first the regular and after a few days the sports version. I keep the regular on my BMW which was a pain driving and the other one at home. I would recommend.

*****5.0 out of 5 stars Help for back pain!

Ergo21 Lumbar and Sports Cushion on her wheelchair
I am a long term, chronic back pain survivor. I’ve recently been confined to a wheelchair for several months due to foot surgery. I’ve been searching for cushions to make the wheelchair more comfortable. Enter Ergo21 products. I chose the sport seat cushion to combat butt fatigue, then discovered the lumbar support for my back. These two products make sitting in a wheelchair much more comfortable! That comfort, combined with excellent customer service make for winning products. Try it, you’ll like it!!

By Country GirlVerified Amazon

I love this seat cushion. I have been trying out different seat cushions to alleviate the pain in my back and legs. I’ve tried a memory foam cushion, and another highly rated ergonomic cushion – both were able to reduce the pain only slightly. This is the third type of cushion I tried. Within a day or two I was no longer in pain while driving or sitting.I ordered another one soon after. Great!

Thanks for the feedback! We looked at 19 different foams, then narrowed it down to seven. We chose this high resilience foam, that doesn’t bottom out and at the the same time offers support. The layer of LiquiCell prevents hot spots which prevents shifting, thereby keeping the spine and neck aligned to give you long term pain free comfort. Feel free to all on us anytime we can be of assistance.
