I'd guess, from what you write, that the speculum your therapist used was the old fashioned, stainless type, perhaps with a stainless, perhaps Teflon, obtuator. Such speculums were common, if not the only ones available, until about the mid-1980s. In the early days, my fist therapist used those on me also.
They had to be washed to get any poo off, cold solution sterilized, then autoclaved, between clients⊠a lot of work. The water and waste hoses were typically amber latex surgical tubing. They were quite expensive⊠not far off 1/10 the price ($400 to $700) of a colon hydrotherapy machine.
In about the mid 1980s, a few years after I started getting colonics, Dotolo came out with the first (AFAIK) disposable plastic colonic speculum kitâŠ. nozzle, obturator, water hose, and corrugated waste hose⊠that was interchangeable with the stainless one.
The stainless ones were heavy, about 2 to 4 pounds, and sure felt cold when first inserted even though stored at room temperature. Because of their weight, they tended to slip out. The end of the speculum was straight, and many still are, so there was nothing for the anal ring muscles to âgrab ontoâ and it'd slip out. Hence the string you describe. My therapist used a narrow, ca 1" wide, strip of cloth.' of the hose while the client was filled
The only real difference I noticed was that âcrimping the waste hose to cause a pressure pulse into the clientâs hose was less intense or effective. I always loved it when the hose was crimped. It is especially great at getting the water up higher, if poo is encountered.
I did, after both hepatitis and HIV became common and known, start to become far more careful, and today would NEVER allow use of a stainless speculum I didn't own.
The speculum doesn't really make any difference. There are now at least a half dozen different plastic designs. Some are one piece, some two. Each has it's pluses and minuses. Some are easier to insert, some pass poo more freely. Once any of them is in you and the water starts, you'll fill and poo, and that's all that really matters.
Very good theapists know how to massage your tummy deeply to work the water fully around your colon and then wok tye water and poo back around, down and out. The massage is, IMO, essential to an effective colonic.
