AVOIDING PAINFUL INSULIN INJECTIONS

This week I heard a new at bbc news about a great researching about a lot of current inventions which will help to the diabetics people to avoid the painful insulin injections.
I was really surprised while I was listening that new which is about a new invention which would help to daibetic people to avoid having to give themselves injections.An automatic insulin pump is already available, which means that fewer injections are needed. The needle is sited under the skin, and it only needs to be changed every few days.
It's connected to a small electrical pump that is situated to a belt or waistband. When insulin is needed, the user presses a button and insulin is liberated through the needle.
Other important advances which have been studied are painless ultrasonic injections baut the problem is that are really expensive.
Pancreatic cell transplantation from someone without diabetes are transplanted into someone with diabetes, are already showing good results in scientific studies.
I think that is really great all this kind of inventions and researches because so many people nowadays are affected by diabetes, abd it will help them to treat it as painlessly as possible.
