Curious robot-in-a-pill completes a successful human test / Boing Boing



RaniPill is another syringe that you can swallow to get blood into the blood from inside. This is caused by an interesting and complex mechanism involving a chemical reaction that infuses a small polymer balloon to push the needle into the intestinal wall. Rani Therapeutics has just completed a successful 20-person study using pills that fill the blanks. From IEEE Spectrum:

Working Outside RaniPill consists of a special coating that protects the pills from gastric acid juice. Then, when the tablet enters the intestine and increases to a pH of about 6.5, the coating dissolves to reveal a deflated biocompatible polymer balloon.

When it enters the intestinal environment, a small pinch builds up inside the balloon, causing two substances to be compressed in both directions to mix and produce carbon dioxide. This gas inflates the balloon, and the pressure of the inflatable balloon forces the microplate filled with the selected drug to dissolve into the intestinal wall. The human intestine lacks sharp pain receptors, so the microshot is painless.

However, the intestinal wall has a large number of blood vessels, so the drug quickly enters the bloodstream, based on animal studies conducted by the company. The needle itself dissolves …

The participants handed over the balloon residues within 1

-4 days.

(founder Mir) Imran calls the device a robot, although he has no electrical parts and no metals. "Although it has no brain and no electronics, [works through] is the interaction between science of science and body chemistry," says Imran. "It does one mechanical function of its own."
