Apparatus for Facilitating the Birth of a Child by Centrifugal Force

I was surprised to note that this was patented in 1965 and has not yet been used, to my knowledge. Granted, its use is not necessary among the "more primitive" people of the world -- so the patent description tells me -- who have developed all the necessary muscles for a swift and easy childbirth, presumably by laboring in the fields and so on. However, I know that on my very own friendslist I have several "more civilized" people whose jobs do not allow them great opportunity to "develop those muscles necessary in confinement". This device is for you. Look at the design! See how easy! They just sort of strap you into this giant piece of machinery, and then you go SPINNY SPINNY SPINNY WHEE WHEE WHEE!!! until the baby pops out! Dude, this sounds SO much more fun than a water birth. Who's gonna be the first one on my flist to try it?

And then the newborn is (presumably) thwapped on the the head by (effectively) 4.2 kg (~9 lb) of placenta that the machine is also helping to deliver fling across the room.

Thwapped on the feet, you mean, after crashing head-first into the net, which, according to Newton's Third Law, is equivalent to the kid being hit on the head with 62 lb of force...

...Actually, in that case, it probably *would* be better if the baby were delivered feet-first.

Er, yes. I'm accounting for some unspecified degree of umbilical bungee, I think, and the weight of body and limbs rotating the kid at a point somewhere around the neck following the initial impact with the OMGNET (and attending interactions with Newton's First and Second Laws).

Yeah...not to mention, if we're actually accounting for all the forces at work, the baby won't actually be moving *that* fast on exit; the centrifugal force is, after all, intended to overcome other forces that are already at work.

My next quibble, though: if the kid hits the net head first and then rotates around the neck...what are the odds of the neck snapping?

Accounting for all the forces takes the fun out of ridiculous!physics. (And being suspended by the feet at 7g is probably not recommended for neonatal health anyway.)

And that's... a very good question, actually. Even without actual snapping, there'd still be a Very Significant risk of spinal cord injuries from (I think) C3 to T1. Which would make a properly-snapped neck quite merciful, really.

Yeah, and being suspended by the feet at 7g and then dropped on your head is probably even worse, with or without the pivoting and neck-snapping that may follow. Being whacked on the head with the placenta would probably barely register, after all that.

And then it's still a net, where the force of the impact is focused onto a very, very small proportion of the surface area. So, further injuries, skin lacerations, and an outside chance of diced placenta if it somehow misses the mechanically-battered neonate.

I did not get to this conversation while it was going on on account of work duties, but allow me to come in belatedly and say that this is almost unquestionably the best conversation that has ever happened on my journal. OMG.

Even with the diced placenta?
