Subject: Spring-loaded manual suction controller - ideas?
Date: 13 Aug 92 12:20:21 GMT
Organization: University of Adelaide, South Australia
Originator: dparsons@ache.mad.adelaide.edu.au

I am need of a fingertip pressure, manually controlled suction controller forc
use in a series of respiratory experiments.  We are looking at energy use in
cystic fibrosis children, who cough up small to copius amount of thick mucus.
They have a nose and face mask that must stay on during the coughing, so that
any mucus they get up will lodge in the mask.  Naturally we would like to get
it out easily.  We have some suction ports (grometted holes to fit standard
tubes) that work fine to get it out, but for other reasons we need to minimise
the gas loss through this suction line... so we want to give the patient their
own control of the suction line.
But, we've not come across any simple controllers for this, that could be placed
in line and controlled by the child when needed.  It seems so simple that there
must be something suitable out there, or easily modifiable from some other use.
Any help: suggestions, companies to approach, refs to published papers, etc
would be greatly appreciated.
PS.  The suction needs to be "quite strong" to work on the CF mucus. Sorry, I'm
not where I can work out a suction pressure value; I guess as that pressure m
requirement increases, so does the 'spring loaded' force required, unless a
pilot valve type of controller can be found.  Oh, yes I just noticed I left out
that it needs to be spring loaded, so that it could be controlled with thumb-
against-forefinger pressure.

Hi,

I am a graduate student at WPI and I am trying to make composites of
hydroxyapatite - tri calcium phosphate. I would like to know the various
methods that could be used to make them. Their application will be as
follows:

The polymer-ceramic composite should be biodegradable as it is supposed to
be used as a resorbable bone replacement. I should be in a position to make
shapes of various bones out of the composite. So the method of manufacture
should be such that it should allow me to have the flexibility of making it
in the shapes of the different bones in the human body. 

I would like to have pointers on the various Journals and papers in this
topic. 

thanking all those who spent their time reading this..

   Here's a possible to find the BP from a finger cuff given only the
diastolic BP and the voltage/light intensity at the diastolic BP.
   Once you get the max's and min's and the diastolic BP, you can cal-
culate the BP from the voltage via the formula:
 
 
               BPdiastolic           BPmax
  BP(v(t))=   -------------v(t) or  -------v(t), where v(t) is the volt-
                  Vmin                Vmax
 
  age coming out of your photodetector.
 
   You'd have to re-calibrate each time you hooked up to the device if
you wanted a really precise number. But this would work if you wanted
an approximate reading.
   The above formula also assumes a linear relation between voltage, trans-
mitted light, and blood flow. Wheter that assumption holds is ???.

I don't know if the Casio unit works this way, but the FinaPres unit uses
an external cuff around the finger, and the pressure in the cuff is
controlled to maintain a constant absorption of an IR beam.

The electronics types here use a device about the size of a tube of 
toothpaste for suctioning solder away from a connection.  It is called a 
desoldering pump; it is spring loaded (manually set) and has a thumb 
release.  When the release is triggered, the spring retracts a piston and 
draws solder in through a teflon tip; the tip would probably interface well 
with various types of tubing.  The capacity is only about 14 cm3, so it 
may not be big enough, but still might be worth checking out.  They
cost about $15-20 and are available at Radio Shack or other electronic 
parts supply houses such as Newark or Mouser.  Hope this helps.

From pictures of the Casio unit, it _appears_ to determine the BP
with an emitter/detector combination that is measuring capiliary flow
in the finger tip.  This was real popular in the old days ( 70-80s )
to get an idea of blood flow at an extremity ( your finger or toe ).
The problem is that there is no reference ( that I know of ) to base
the BP reading on.  


Any ideas?

 That data, I recall now, is from electron impact mass spec system.
 So at about 10e-6 torr, the sublimation temperatures are (approx)
	C60: 330 C   ; C70: 400 C
 At atmospheric pressure: (approx)
	C60: 480 C   ; C70: 550 C

My suggestion is to turn towards a teflon "hybrid" Check the Cole Parmer cat-
alogue for possible alternatives.  Speaking from experience, we use a flexible
teflon type tubing in a chromatography system that is exposed to THF 24hrs/day
no problems - I believe it is FPTFE.

My lab is looking to purchase an a/d board as well as associated software
for an Apple Macintosh computer.

Any help/advice/product info/tales of never ending nightmares would be greatly
appreciated.
