Problems solved by technology

One is that the mouth of the infusion bottle / bag is sealed with rubber parts. The use of rubber is very expensive. When the steel needle or plastic needle of the infusion set punctures the rubber part of the infusion bottle / bag, it is easy to drop rubber particles into the infused liquid. Rubber entering the blood vessels of the human body is very harmful to the human body; the second is that it is troublesome to use, and there are hidden dangers of safety. The infusion sets on the market are all steel needles or plastic needles to puncture the infusion bottle / bag.
