Can you guess what this historic patent is for?

Here's an image from a patent filing made in 1931. Now, what do you think it is?

I'll give you a hint: It's a medical device.

  1. “Darn it!  I’m tired of having a weak rectum!  Charles Atlas says he can give me a sphincter of steel!  I’ll gamble a stamp and get his free book.”

    1. You only say that because you’ve never done an image search for “rectal prolapse”.

  2. While I’m not a doc, my wife is, and there’s something to this. Some women have issues with the ‘integrity’ of their vaginal muscles after giving birth, or due to age, weight, or some other medical conditions, the results of which can range from embarrassing  to discomfort, to serious health complications. Some of the current solutions like the vaginal mesh have caused major problems (you may have seen the ambulance chasers on tv lately). So the idea of strengthening the vaginal muscles through exercise isn’t really that crazy since it’s relatively non-invasive. I know, women sticking that up the vajayjay seems invasive, but I mean relative to surgery or permanent device implantation.

    As far as the anal usage of the device, I’m gonna leave that one alone :)

    1.  I was going to say something similar. I’ve read that quite a few women suffer problems relating to damaged vaginal muscles, but since that isn’t something people feel they can talk about even with a doctor, well…
