DSh device name and logo

When something’s stuck inside your way
And blocks your breathing track:
You wished to breathe, but here you lay,
Just wishing to get back.

But then they put upon your face
A mask to clear the pipe.
The patient’s back from death’s embrace!
Now breathing, even gripes!

The logo has a soul within,
The name comes from the heart:
Just two letters make you grin—
DSh—breathe from the start.
