Unlocking the secrets to solve the problem
Once you understand the problem, the solution can be so obvious! The patented BackBone turning wedge ™ represents an evolution of how form follows function.
Turns out, when I began to understand why wedges slip out of place, it was clear what changes need to be made to make one work well. First of all, in our zeal to get a 30 degree angle, wedges have lost sight of the real goal. That is to remove pressure from the sacrum without placing pressure on the greater trochanter. The flat surface of a straight wedge cut to 30 degrees is too steep to support a person at that angle because a persons’ back is not flat. Especially as we get older, our spines tend curve out, and when we turn to the side in bed we tend to curl our backs. So when you place a 30 degree angled wedge against a rounded back, not only is it impossible to get the wedge all the way under the person, but you will actually turn the person greater than 30 degrees and closer to her trochanter. This is why they slip out of place all the time too. When the wedge is to the side, the persons body weight puts a constant lateral force to the wedge, pushing it away. Wedges fitted with a “no slip” surface are great at sticking to the bed sheet, but if the bed sheet cannot stick to the mattress, the wedge only takes the sheet with it.
Another thing I noticed in my nursing practice was that, if a person possibly can, he will always do one of two things when supported by a conventional wedge. 1. He will shift his hips to make himself flat on the bed again, or 2. He will roll all the way onto his side. He does this because laying at a half way, 30 degree angle is like trying to sit half way down. If you are not well supported under the direction your body is heading, your body will feel like it needs to keep going to get to a natural position. Since a conventional wedge supports to the side, the person feels like his back is not supported, so he shifts to a more supported, natural position.
The secret to an effective wedge is that it must fit under a person and across her entire back and hips! A wedge under a person will achieve lift, support and the person’s body weight will push downward and hold it in place. The only caveat is that it must support without touching the sacrum.
The secret to the BackBone’s success is in its unique, bilateral angling and contour design. Since the wedge is cut to the lifting angle on two sides rather than just one, it is possible to get the wedge all the way under a person’s back. The person rests on top of the cushion with an even, gentle lift so they feel well supported and wedge is pinned in place. The contouring shape conforms to the natural “curl” of a person’s back while supporting the hips to achieve a form fitting, ergonomically correct position, even when he is in a semi-fowler position. Pressure reduction is efficient because the BackBone will support while curving away from the sensitive bony prominences of the spine, especially the sacrum.
The BackBone Turning Wedge is a patent pending design because it is the only wedge design that can live up to all the challenges a wedge faces! Once you try the BackBone Turning Wedge ™ you will see why I say the BackBone is the best turning wedge in the world!
