Been around since: 2013
Unique Design?: Yes (This cup design appears to have been created by this brand and has not been seen used by other brands)
Other Details: Has a hollow stem with a valve that allows you to empty the cup (every 4-8 hours is recommended) while it is still in place. They appear to sell a special steam steriliser as well. The “discharge points” where the cup can be emptied via the stem, are on the sides of the stem. So it appears that you’re just relying on the ball being pushed up above the holes and staying there…. or else it would leak when you don’t want it to. Also menstrual blood is often clotty, so I’m not sure how well this can handle clots. The video (which is a bit hilarious :P) mentions clots and the fact you can just squeeze them out…. but I’m not sure that would work in practice. I’d be interested to hear from anyone who has used it.
It appears you push the ball into the “discharge valve” spot to seal the stem, then push it down to the end to empty it.
