While intravenous needles need to be rigid in order to pierce the skin, that rigidity sometimes causes damage to the veins. A new needle addresses that issue by softening upon insertion into the patient's body – plus it reduces the likelihood of needle-poke injuries.
There is a whole lot of nonsense in this “article”.
No one has used and left rigid needles in the body (outside of dialysis) for many, many decades. It is a plastic (of varying types) catheter over a steel needle.
One that catheter is introduced, the needle is removed. Those catheters are designed to be flexible.
No information on flow rates. No information on safety in hyperthermic patients. No information on its safety in hypothermia patients. How well does it do when the patients body temp is 85°F?
The IV tubing in the background very much looks like it has latex on it, which has basically been eliminated since the late 80s.
In short…sounds like nonsense.
