cannula

The bionic pancreas, a credit card-sized device called an iLet, monitors a person’s levels around the clock and automatically delivers insulin when needed through a tiny cannula, a thin tube inserted into the body.

The patient was far from needing a ventilator, and with his blood oxygen saturation around 95%, he wasn’t eligible for a nasal cannula under the current rationing orders.

Attached to the handle was a thumb-rest and a tube for removing or adding fluids and a perforator within the cannula.

Inside the cannula is fixed by oxidation an obturator, which carries on its end a small handle fixed on in T-fashion.

The iodoform is injected by means of a glass-barrelled syringe, which is firmly screwed on to the cannula.

Wind colic may need prompt use of the trocar and cannula to puncture high up in the right flank for liberation of gas.

The tube, thus prepared, was connected with the artery by a fine cannula, exactly fitting the artery.
