Liquid Glycerin Injector
I know that I've posted before about my favorite D-I-Y injector for liquid glycerin, but I'll do it again because I think they are really cute and fun to make and use. I'm pretty much going from memory; I haven't made any in at least a year. So: start with a Fleet cleansing enema; it must be a Fleet brand. You'll only need the nozzle tip. Unscrew the nozzle assembly and you'll see that the rectal nozzle proper is a separate unit of softer plastic, which snaps out from the part which screws into the bottle and is of harder plastic. Examined carefully, you should see that the soft rectal part has a groove built into the inside of the nozzle, near the base. (Apparently, that is for more flexibility - my guess.) The soft rectal nozzle piece is the easy part, and it is all you'll need from the Fleet.
You will also need a very particular sort of disposable oral syringe, of size about 10 cc (10 ml). It should be as close as possible to the Covidien brand sold by Amazon: item B01HDXZR5E at ten for about $5. (Get neighbors to go in with you! If you live in a large apartment, they also sell 100 as B01BQA7GOK!) The attraction of this particular unit is the top-hat-like cap. Carefully cut off the end of the cap with a sharp knife or single-edged razor blade (commonly used for scraping paint). Next, push the cap - now, an open cylinder - onto the end of a pencil, hat-brim first; that's to hold it so it can be cut precisely without cutting off any fingers. With the blade, cut evenly around the cylinder about a sixteenth of an inch (or about 1.5 mm) from the hat brim, or flange. The result will be a shoulder washer, easily made from what you already have.
Don't remove the washer from the pencil. Instead, use the pencil to shove the washer into the Fleet rectal nozzle. Unless they've changed the design, the shoulder washer will just fit perfectly into the molded internal groove in the nozzle shaft. Carefully remove the pencil, and firmly push the rectal nozzle down onto the nozzle of the oral syringe. With firm pressure it will push down all the way to seat against the syringe body. The sholder washer will fit tightly and hold the rectal part securely.
What you have now is an attractive and efficient rectal syringe, easy to use and easy to clean (just suck a bit of soapy water in and out). When the nozzle gets grungy it is easily replaced, reusing the shoulder washer to hold a new nozzle in place. To carry in a purse, cut or grind off most of the finger-hold tabs and the unit will just fit into a common toothbrush case.
I find liquid glycerin to be very helpful when I just need a push to help, and a really tiny bit does it for me. I fill it with 2 or 3 ccs of fluid - just dip it and suck it in - and inject as little as I can, maybe 1/2 cc. By the time I'm done brushing my teeth I usually feel an urge developing well. Then I inject the remaining liquid and the urge gets overwhelming by the time I sit on the pot. BTW, after rinsing, don't seat the syringe plunger fully or it might stick; just leave it about 1/4" from fully seated. Love to everybody and everybody's bottoms!
