I made this last night as a thank you gift for the nursing staff in my weight-loss program.

I did not use a pattern, I just started at the plunger end and faked it.

OK, without having the syringe here to look at I will give a very vague tutorial

I started at the plunger end with grey. It is about 1 1/2 inches in diameter. I just chained about 4 or so, closed the loop and went in the round increasing just enough to make it bowl shaped. Cut and weave in your end.
To make the stem of the plunger, crochet a cylinder either by hooking it directly into the "outside of the bowl, or crocheting it separately and stitching it on. This piece (also grey) is maybe 3/4 inch in diameter and 3/4" long. (maybe a liittle shorter, and maybe the thumb part is a little wider)
The part where you put your index and middle fingers is just a big flat circle. You again can keep it simple by creating this piece by itself and then continuing to stitch the pieces together. (remember, crafts are supposed to be fun, not stressful!) This piece is about 2 1/2 inches in diameter.
Color Change! In white, make a cylinder approx 2" in diameter and maybe 1 1/2 inches long. (depending how much blood you plan to put in there
Switch to red and continue your cylinder for about the same length.
Switch to grey and go just a couple of rounds, then increase for a couple of rounds to make that edge.
Again, personal preference whether you make the next (icky) section directly on the previous part, or if you make it separately and sew it onto the previous piece. I honestly cannot remember how I did it, but I think it started at the wide end and decreased willy-nilly until it was ridiculous to crochet anymore. That determined the length of the pokey part.
I embroidered the face and measurements in fuzzy black.
Oh, and I tend to crochet pretty tight and stuff the heck out of things LOL I can't help it... If I did it over I think I would try to make the body even firmer though so it could serve as something to grab in your fist while they search for prospects. 'Maybe even stuff it with a gauze roll.
My guess for a thermometer (I will have to make one of those and the blood pressure gadgets too.) you would make a nice long cylinder and then increase and decrease to make a nice bulb at one end. I embroidered the syringe features rather than changing colors while crocheting. I am only a beginner, so easy is the theme. It would be cool if you were experienced with color changes and carrying the second color along to do it white with a vertical stripe of red and then red in the bulb... or is it silver for mercury... I guess I need to look at a classic thermometer again.... or maybe I will make an ear thermometer LOL
Thank you everyone for your kind words of encouragement. I am enjoying learning to crochet and like making odd little things best.
If anyone who does not crochet is interested in some sort of personal swap, I would be up for that

I am willing to take requests too... no object too strange
