I need more informatio n to understand this clearly. As a Retired Mechanic I have to break things down to the individual parts to see how they work together. An 'access site' basically some form of 'hose' getting punctured by a sharp needle repeatedly in almost the 'exact' same position every time, Do I have that part correct?In my way of thinking, even with material that is available today this repeated punctures may leave a small 'opening' making it easier for the next insertion. I'm OK with that. The part that gets me is what keeps this 'hole' from leaking when the needle isn't there to block the opening?Artificial materials are only so good. I don't know of anything that seft-seals so well.But then what do I know? I'm just a 'Guy' and a mechanical wizard. I didn't bother to finish my Bachelors, much less go after my Masters.But I did end up staying at a Holiday Inn the other night in Columbia because of the ice.
Sticking sharp objects into one's body seems to run counter to EVERYTHING! And seems like such an abnormal thing to be asked to do. I just can't imagine it and consider you HHD folks a true breed apart.
