Went for the fitting of the "test" / clear upper yesterday afternoon. This is the part that holds me to the prosthetic. It is accomplish by creating a vacuum. You will be able to see the hole where the vacuum plug will be placed.
Here it is in a couple of views.
Then I used the normal procedure, with the parachute like bag, to put my residual limb into the prosthetic.
Here is the front view. I will do better with the camera next week, we were in a hurry for some damn reason. You can see where the vacuum plug will go. Here I am holding it on with my hand. When I put it on a chair and put any weight on it I was coming out the hole for the plug.
This is the view from behind. On the bottom of the residual limb you can see a small void. That always seems where the air pockets sneak in on the upper I have now. Sometimes I can not get the air to move around to the vent so I have to take the prosthetic off to get it adjusted. That is one of the reasons we are making the new one.
