This is a summary of the cute little glycerin injection syringe I described - posting as jillie - probably seven or eight years ago. (I lost all my logins and e-mail and so on while out of the country the last few years.) Reader ThatAussie asked me to post it but I do not have the time to actually make one and take pictures now, likely for weeks as I am just getting settled in back here - but I am posting this description for the interim at his request.
WHAT IT IS: A cute and compact mini-enema for glycerin and glycerin-water mix (like the Japanese fig enemas).
WHAT YOU WILL NEED: One genuine Fleet-brand disposable enema (the squeezie type); one oral (infant) syringe ; one sharp knife or single-edge razor blade. Optional: tube-style toothbrush holder from dollar store.
NOTE: The oral syringe is fairly commonly available but it MUST be of the type shown as item KND8881907102KND8881907102_bx on Amazon. Study the picture. That is a box of 100 but there are plenty sold in onesies and dozens; I just don't have time to search right now. It MUST be supplied with the TIP CAP exactly as shown in the Amazon picture - it is like a little hat.
PROCEDURE:
Step 1 - Using razor blade or knife cut off end of the cap so the hat-brim is attached to most of the cylinder but the plugged end is cut off.
Mount that on the end of a pencil to provide a means to hold the cap securely.
Step 2 - Using the knife or blade cut the cap again, as straight and evenly as you can, so the hat-brim is attached to only a bit more than 1/16 inch of the cylinder. That forms a 'shoulder washer' and is the only part of the cap that we need. If you absolutely cannot find an oral syringe supplied with a cap of that style you may be able to find a nylon shoulder washer of similar size in a hardware store, but that's a hassle.
Step 3 - Buy and use the Fleet enema as intended. Save the tip (nozzle) assembly.
Step 4 - Disassemble the tip into two parts, one soft and rubbery (the tip proper) and one threaded and knurled (the bottle cap part). Save the rubbery tip. Clean it well. Now - I must say that I have not made these for years so I am assuming that the tips are still made the same way - inspect the inside of the tip and see the ring-shaped recess molded into it near the base. (Only Fleet-brand tips were made this way; others to my knowledge have smooth bores through the nozzle.)
Step 5 - Place the tip-cap-shoulder-washer onto the tip of the syringe, cylinder part first. It will fit tightly about halfway down the syringe tip.
Step 6 - Place the Fleet nozzle over the syringe tip and washer, and press very firmly so it seats all the way down. The shoulder washer should just fit into the molded ring recess in the nozzle to snap in and hold it firmly and prevent leaks.
Step 7 - That's it. The Fleet sheath or over-nozzle should still fit if desired. The syringe is easily cleaned by rinsing and then sucking water in and out a couple of times; glycerin is bacteriostatic, anyway. When you put it away after use try pulling the plunger back out 1cc or so, to prevent sticking if it is stored with its plunger seated all the way.
Step 8 - Optional, for purse or travel. Use diagonal cutters or a similar tool to cut off most (but not all!) of the finger-holds, and it will fit perfectly into many cylindrical toothbrush holder tubes. (Have hubby do this and then grind smooth or file what is left for the finger holds. Leave as much finger-hold tabs as will still allow it to fit into the toothbrush tube.) This makes a sturdy syringe and quite professional in appearance; also, it is fairly easy to use. The base of the Fleet nozzle will cover the end of the syringe almost perfectly. When it gets grungy just pull off the nozzle and put on another - from another Fleet squeezie.
I find that for me it is best to fill the syringe with 3 to 5 cc of glycerin-water mix (just suck it in), then to inject a tiny bit - maybe one-half cc - then to squirt in the rest after about two minutes. If I need more than that I do a big enema. Well, guys, hope that is helpful till the Technicolor version comes out!
