1. How do you make sure the Health Monitor has enough straws? It means you need staff to check and refill the straws every few days if the straws are stored within the machine. Multiple times a day if they are in a dispenser, because kids will take them all. Have you taken into account the costs of refilling straws?
2. If you store the straws inside the Health Monitor, you need to design and construct a dispenser mechanism. Have you take into account those costs?
3. Is it possible for the straws to release particles that influence the measurements?
I don't think it will cost a lot for straws. Because from the video i saw they are just regular straws which are very cheap.
Also, i believe the machine isn't that small and hundreds maybe thousands straw can be put its dispenser.
wondering about R & D budget. Have you reserved fund for research and development and FDA approval process? how much percent?
