I had to have enemas given to me almost from birth. It wasn't until I was in my 30's that doctors finally diagnosed me as having a colon that portinns had no muscle nerves or at least got no nerve impulses to move fecal matter along.
So my mother gave me enemas almost daily. When I was 11 or so, I got the doctor to teach me how to do enemas myself. He perscribed JBL Cascade sit on enema bag. These bags were made in England and distributed by Tyrell Hygenic Institute.
So I started to use the bad myself.
we had a low rocking chaer that I used to sit on with the bag. I always started out with a soap suds enema taking in two fills and then changing over to clear water. At age 11 I probably only took in a quart or so of fluid at each filling. But as I grew older I gradually took in a lot more.
The JBL Cascade was made of heavy rubberized fabric. It was kidney shaped and held a little over 5 quarts of fluid. The nozzle was fairly thin about 3/8 of an inch in diameter and about 3 1/2 inches long. It had 4 rows of holes along the sides probably 12 holes in each row. The nozzle was screwed into a domed valve which was about 1 inch high and a little over an inch in diameter. The valve was controlled by a valve stem which was about 8 inches long.
To take an enema you put your hand between your legs as you crouched over the bag and used the valve stem to guide the nozzle into your anus. After you were seated you controlled the flow of the water by turning the valve stem.
This was a very comfortable way to take an enema and I used to sit and read as i took in water. Sometimes taking 20 or more minutes to fill up.
I used these bags for daily enemas for at least 60 years.
My mother kept my original bag when I moved from home. I purchased my next bag in 1952 for about $24.00, and my 3rd one in about 1972 for about $35.00.
The bags now being sold as JBL are a poor copy and I found uncomfortable to use and mine sprung a couple leaks after only a few times of use.
Since I still need almost daily enemas, I now use a professional colon therapy machine which is very effective but not as convenient as my old JBL Cascade enema bags.
