I just received an email from someone who we will call Dave (because that's his name). Dave says:
Hi Max, I hope you don't find this is off topic, but you're interested in so many things I thought you might be able to help.
My 5th and 6th cervical vertebra are somewhat compressed. Actually almost all my cervical are not doing so good, but the docs say that 5 and 6 are the worst.
Physical therapy has helped, but to avoid the weekly trips to the physical therapist's office – plus the $20 per visit – I purchased a traction machine for home use. (Lucky this was covered by medical).
The down side is the home machine is manual. It has a small hand pump that cranks up a piston which is connected to a tram. For 20 minutes every other day, I lay on my back with my head fastened to a tram by Velcro and I "neck stretch" to 30psi for 1.5 minutes then rest for 0.5 minutes.
The good news is it works. If I miss a couple of sessions I certainly know about it.
The reason I told you all of this is so I could ask you the following...
Being an EE, I'd like to automate the manual operation. My biggest problem is I cannot find a small electric pump (for under $20). This only needs to pump up to 35-40 psi with a response time in seconds. I can do the programming and sensing but without the pump I'm stuck.
Any suggestions would be appreciated.
I thoroughly enjoy your articles. Keep up your great, enjoyable writings! Dave
Well, I was growing afraid that Dave was going to drop the ball and forget to tell me how wonderful I was, but he made a brilliant save right at the end (grin).
Now, I'm not an expert with pumps, but I know that the EE Times readership includes expertise in every subject known to humankind. So if you have any suggestions as to an appropriate pump, please post them here as comments or email them to me directly at max@CliveMaxfield.com
and I'll pass your thoughts on to Dave.
PS Let's start with any pump that can do the job, irrespective of the price, and I'll take it from there. (If we find one for $20 or less, that would be a bonus, of course.)
