Robot allows doctor to check on hospital patients remotely

In the future, patients in hospital may be attended to by robots instead of doctors or nurses. The invention will allow doctors who are not at the hospital to remotely check up on and speak to patients using a videolink.

Other gadgets include smart phone apps that keep track of the user's heart rate and blood pressure.

These are just some of the health-related inventions being showcased at the Consumer Electronics Show (CES) in Las Vegas.
