Innovative Nurse With Some Design Questions

[NurseINNOVATOR]

Hello to all- and let's just take a moment to THANK GOD for Glorious ENGINEERS. I love em'- smart bunch of kids you guys are...HOLY MOLY!

I have some questions about a medical device I have designed. I am looking for maybe a student, or someone who has a little extra free time on their hands, to offers some troubleshooting regarding my device design. I've actually already filed the provisional patent, had it for a year now, and am re-filing it due to the addition I want to make to this device. I've had it 3d printer proto-typed already, and all the CAD specs are already done. I'm FINALLY at the end of the 'design road' so to speak - and of course, I would like to add something to it that I think only an engineer could make simplistic and manufacturing-friendly.

If anyone is interested in taking this ride with me, I'm certainly NOT a greedy person, and will absolutely share my successes! I've already got a couple people on board who did most of my CAD work, and design - however, for this addition, I believe I need someone who is more mechanically inclined.

Thanks so much everyone!!

I forgot to add some pics, and did not see an 'edit post' option, so I'm just going to add my media via this route, Sorry guys- newbie here!

HERE IS A BASIC COMPARISON, OF WHAT I AM LOOKING TO DO, WITHOUT GIVING AWAY MY IP!!

I am a lowly road engineer but I am sure someone here can help out!

so what does this device do?  the roller part? my wife is an ICU nurse btw..

What is the question(s)?

 

[matt267 PE]

What is the question(s)?

Do you want to be a test subject? 

 

[ptatohed]

Do you want to be a test subject? 

For you, no.  For NI, given her avatar pic, yes. 

 

[NurseINNOVATOR]

Uh....The question? 

What are my heat integration options?

 

[P-E]

Finally a use for spent uranium fuel rods!

Sounds like a question for an electrical engineer.

(I only know about wastewater.)

Yup batteries or power cord.  Then some heat transfer to the wheel.

Does the wheel HAVE to be metal?

This seems like a suitable thermoelectric application.  Which leverages the Peltier effect to create a heat flux between the junction of (2) different material types.

Looks like a pasta cutting wheel.....

Ceramics can open up a lot of options.  Hadn't thought of something like a Peltier module.  I do have some heat treatment experience, and was leaning more along the lines of a ceramic wheel with an embedded heating element.  Current can pass through something as basic as a spring loaded contactor.

It will assist with wound care patients

Good LORD....like......huh?

LOL.

You sound ridiculously smart human. So, English please?

yep! it's damn near the same exact concept...except I'm having a HELL of a time figuring out how to make the wheel heat to a temp that wont burn skin. ugh.

It does NOT have to be steel...as long as it can withstand washing, AND possibly autoclaving if surgical grade is implemented.

 

[knight1fox3]

What is an approximate range for the desirable wheel temperature?
