Largest Rectal Thermometer Size

The Kinsa is not large. It is about the diameter of the old mercury thermometers for about three inches and then expands somewhat, but it’s still not as thick as a Geratherm. It works very well though, and keeps a record of your temperature readings as well as how it was taken(oral, rectal, axial.)

You mean one of these?

Oh, now that looks very tempting!

I have an Ekco kitchen thermometer that’s used for deep frying, candy and jelly making. It’s 8 inches long and 1/2 inch diameter. Perfect for needy bottoms. You could probably find one at a good kitchen store.

I've looked around for the Geratherm pretemp, but cannot find where I can buy it. The Geratherm Basal is a bit bigger than a regular one, so that might be an option. Otherwise you can indeed use veterinary thermometers or candy thermometers - however I've always had doubts about using kitchen thermometers as I really really don't want glass to break while using it (maybe they're equally strong but I just don't know).

The old timey dairy thermometer was quite weighty with a huge scale.

This one will do someone real proud!

The five inch veterinary glass rectal thermometers are larger and thicker than the standard fever thermometers. Veterinary glass rectal thermometers can also be distinguished by having an integral glass ring on the non-entry end which if removed and the non-entry end finished to a blunt end, it would like like a larger and thicker version of a standard four inch glass rectal thermometer. Such a finished five inch glass rectal thermometer can be substituted for a standard four inch glass rectal thermometer.

@Sanne That looks very similar to the one my girlfriend and I use. Larger width than the average rectal thermometer.

Docshelper010: Glass veterinary thermometers are becoming hard to find, new ones anyway. If you know of a source, would you share it?

I have some 12 and 16 inch glass thermometers that are meant to be used in a lab. Some are mercury and some are alcohol filled. I have used the 12 inch ones but not 16. They are of course thicker than the standard 4 inch mercury thermometer that is for the most part phased out.

I don't spend my nights watching porn but I do enjoy seeing some clips showing young girls ( or sometimes boys ) having their rectal temperature taken. I have noticed that doctors or nurses usually insert in the rectum of patients very small and thin glass (or plastic) cylinders as thermometer.

Is that the usual practice? Are those cylinders only used once? Is there not a risk that those small thermometers end up in the patient's body?

@Svensson , In your post you mention plastic cylinders. Are you possibly referring to the sleeves or sheaths that cover electronic temperature probes?

@poop,

I was refering to US made rectal temperature clips available on the internet. I have not seen those small thermometers in European made clips on the subjet.

For sure, the old glass American thermometers were very different from the ones used In Europe. In the U.S., the glass thermometers were narrow cylinders, about the width of the “neck” of old European (and current Geratherm) models, and about 11cm long.

The bulbs designed for oral use were long and narrow, intended to maximise contact with soft tissues in the sublingual area. The bulbs on rectal thermometers, on the other hand, were short and stubby. Compared with European thermometers, they were intended to go deeper inside, with the blunt bulb resting comfortably against the wall of the rectum. That obviously gives a different, but no less interesting, sensation to the lucky patient.

To this day, the sight of a “stubby” bulb thermometer remains extremely evocative for me, as there was no doubt about where it needed to be used.
