Diagram or schematic?

[68CatFan]

After reading a few threads about operational issues with 3-piece implants I started looking for a diagram that shows the internal components of the valve portion. Either Coloplast or AMS will do. I cannot find one unfortunately. I would assume there are check valves to keep fluid moving one way and that the button is used to select between which route the saline can travel. It sounds like you can depress the valve to drain the cylinders but squeezing the bulb is what forces the valve over to the "fill" position.
Does anyone have a picture displaying the internal components of the valve? It could help new patients understand how their implant works and help them resolve problems. Also I'm an aircraft and an auto mechanic. Taking things apart and figuring out how they work is an obsession for me. Thanks.

I feel the same way. But I was unable to find any machine drawings of the valve mechanism anywhere. I did find some illustrations of the internal workings of the valves for both manufacturers, but they were not helpful in discovering how they worked.

So, I wish you luck. And if you find something helpful please let us know in the forum or let me know through private messaging, if you please

Fascinating question:

There is a nice video from coloplast that you can watch at the below url:

https://www.coloplast.us/titan-touch-en-us.aspx#section=videos-and-animations_100

Also, Dr Bruce garber discusses the diferences beween the titan OTR and the Titan genesis pump which is available at the following url:

Also, I have attached a manual written by Dr Wilson for coloplast where he discusse tips and tricks (audience is implant surgeons).

A key statement in that manual is:

From Dr Steve Wilson:
Suggestions for Optimum Outcomes
It is a good idea for the patient to cycle his device daily in order to keep
the pump lubricated and avoid sticky pump syndrome. He doesn’t have to cycle completely; just pump it a few times, deflate it and then pump it one time again. This ensures daily movement of the valve in the pump. It is not necessary to press hard to deflate or to keep your finger on the deflate valve for more than a single push. If the patient is having difficulty depressing
the deflate valve, reverse the thumb and forefinger on the deflate portion. Humans have much more power in their thumb than forefinger and elderly patients may not be developing enough pressure with their fingers.
It has also been shown in the literature that the Titan will expand and possibly lengthen & widen the penis if the patient inflates daily for 1-3 hours.7 Patients will confirm this expansion as the number of pumps to full inflation will increase over time.

and finally, here is a engineering schematic of the pump assembly:

Unfortunately, frankly, it does not really show how the inlet anad outlet valves really work---such a bummer. Maybe the companies consider that "proprietary trade secrets !" LOL

Also, I have in this message also provided a link to the coloplast product catalog which has some nice pictures of their product line (but, darn it, no real true diagram which shows how the pin and valve really work):

Finally:

here is a nice photo of the three piece implant by titan:

Thanks for the info Tangerine. The instructional video shows the man pressing (not holding) the deflate button and squeezing the cylinders. Then when you are ready to inflate squeezing the bulb shifts the deflate button back into the inflate position. After the bulb is flat the suction (as it opens up) draws down the spring and ball to allow more saline into the pump. When they talk about a hard pump popping in the tips and tricks manual I think they are referring to the sticky valve portion shifting over to the inflate position.

Good news, wayntho (franktalk member) posted the patent information for the coloplast OTR (one touch release) pump.

here is the link:

https://patents.google.com/patent/US9649217B2/en


please note: there are three versions of the titan pumo currently being used:
1) Titan genesis
2) Titan OTR (one touch release)
3) Titan touch (this is the one I have and is the newest version as of 2016)

to prompt this discussion, here is an interesting comment from waynetho:

The practice of putting one squeeze into a Coloplast implant to keep it from auto-inflating is thus counter to the design drawings and shouldn't be performed. That will allow pressure spikes on the reservoir (from abdominal pressures, coughing, bending at the waist, etc.) to force fluid into the cylinders.

Bottom line, Titan owners should not put one squeeze in after deflation because doing so will defeat the lockout valve and permit auto-inflation.

There is an additional valve in the titan assembly that bionics should know about, it is the lockout valve.
