Glycerin Syringes

About 100 years ago, glycerin syringes were used to make people poo. Reportedly, they were a favorite of nannies because they would reliably produce results but without the chance of messy accidents in times when indoor plumbing was a luxury. A dose of glycerine usually produces a good result within 5 to 30 minutes. For determined resisters, the ironic fact is the longer the effects were resisted, the more powerful the effect.

The syringes were made of early plastic, glass, and metal. But what is interesting is the two styles of nozzles. The most known are similar to a standard enema nozzle, like this:

But recently, I came across this different type:

While I don't know which is the earlier design, they both serve the same purpose. However, I'd expect the syringe in the first picture would be more effective because the glycerin is injected higher up and hence would cause a more intense urge.

What do you think?

It really doesn't make a big difference ,glycerin is an osmotic laxative it works both by drawing water into the bowel and stool as well as local irritation, the liquid is faster than traditional formed suppositories( it doesn't have to melt in order to be dispersed in the rectum ,the more contact with the rectum the greater the irritation)

.

The strength of the glycerin and amount used ,have alot to do with whether it causes and urge to use the toilet or a stronger reaction,also the longer the retention the greater the effect .

You're absolutely right, the top one would be more effective as it gets the glycerin up where it needs to be to work. The problem though is the nozzle end needs to be lubricated to be inserted, and if lubricated with glycerin the burning might cause the dose to be expelled before it really has much chance to work. The lower one, you can put the point of the nozzle against the anal opening and kind of squirt the glycerin past the sphincter without having to really open the recipient up all that much.

Maybe we should get a few of us together for an A/B comparison?

@Sean could you repost some of your classic equipment pictures either to a Zity album or somewhere that hasn't shut down?

When I was playing with my sub I instilled 5 cc of pure glycerin rectally using a syringe. No needle of course. Cramping always appeared within 5-10 minutes and stooling soon after.

Checking the links in the original post produced this message: This service has been terminated due to too much abuse by visitors. 😢

The second set of links successfully showed the two described syringes. My guess would be the one with the longer and curved tip would be the more effective. If concerned with lubrication causing too-soon emptying, a bit of non-glycerin lube should prevent any adverse affects of using a glycerin based lube.

My grandma had the clear one with the long tube. I was a withholder (the toilets were open at school and kids would make fun of me sitting there so i stopped using them). My mom would take me to grandma's. I would take off my pants and watch her fill it and then get on the bed on my belly. She would pry my cheeks apart and put it all the way in. She would put the glycerin in quickly. She kept it in the refrigerator and it was so cold that I would jump when she squirted it. She would squirt in a 2nd one since I was a withholder and put a pad of toilet paper over my anus, then the tape my cheeks together tightly with adhesive tape. I would start squirming on the bed in a few minutes pleading for her to let me go. I don't remember how long I had to hold it, (maybe 15-20 min), but it seemed like forever. I would get on the toilet facing the tank and she would zip the tape off. I had to keep holding it as long as I could stand it until it all came out by itself. Then it was was over in a few seconds. I would stay there for a few more minutes until my intestines stopped pushing. Grandma would put another pad of TP over my anus and then let me put my underpants back on. After that, my mom would give me suppositories before bed so I didn't have to get the liquid glycerin (I still wouldn't use the toilets at school.) The liquid glycerin was better than getting enemas and the suppositories were better than holding a butt-load of glycerine for 20 min.

They are the same pics I originally posted.

Lubricating the long nozzle with Vaseline, including a little bit at the end of the nozzle to plug it, prevents any premature effects.

You could very easily instill glycerine even higher in the rectum than the syringe nozzle using any old disposable urethral catheter. I don’t think the size of the lumen matters for the amount needed to be placed and since your average catheter in a minimum of 14” that glycerine will be loaded higher than most people ever receive a dose . an Average liquid rectal dose might cause considerable discomfort if a long retention is attempted. Also immediate proximity to toilet or being properly diapered will ensure a less traumatic stressful evacuation., people with sensation tend to get panicked when they can’t control what’s happening any longer .
