Are we sure this is an antichoking device? Im pretty sure I saw the same thing in the grocery store and they called it a mini plunger. Same thing I spose, just be careful if you use it twice for different purposes. I mean do it, just don’t tell.
Just remember which end you used it on last.
Yeah, no… if you have someone choking this will probably save a life. NOT intended for any plumbing interventions…
OH! A throat plunger! And they say I don’t need anymore tools…
No, I’m not going to ask that question.
I think the point is to compress the air-column in the device FIRST, then apply it over the mouth/nose and UNCOMPRESS the device to cause a vacuum to pull out the blockage… don’t want to simply force [whatever] farther into/down the airway (as the graphic above seems to show)… it does take some thought. Valuable if the situation ever arises.
“The air will vent out the side…” 
Oh, you’re right of course FL. I guess I have crisis fatigue from taking care of me and mine.
Thanks for being a consistent poster and being on the right side.
If nobody’s told you lately, you show up and make a difference, thanks. 
It says it has a check valve, but there’s no way I’d use that on a person. It’s not like a person is a mechanical object. “Oh, wait right there. I have a special tool for that.”
It’s a ridiculous device, but technically it might be better than nothing. If it pushes the object into their lung, it clears the airway, but they’ll have to be put under and a specialist will have to fish it out with a bronchoscope. I have no particular medical expertise and I probably have no idea what I’m talking about, but I do have a child that once had to undergo this procedure.
Any basic Red Cross training teaches you how to do the Heimlich Manoeuvre. What a gimmick.
Edit: I just noticed that the box says, “CHOKING DEVICE” 
The air-fuel ratio has to be just right
I still wouldn’t use it, but I’m glad it worked for them.
Most people I know still refer to it as such, though you are correct. The last time I re-certified was well after 2006.
