When I worked at medical centers as a Medical Technologist, years ago, we commonly drew blood from branch lines of catheters. So, not much new here. I looked up the patent application (US20160051174 – https://www.google.com/patents/US20160051174?dq=inassignee:velano&hl=en&sa=X&ved=0ahUKEwjsy-SRj5zOAhVi44MKHTPmC70Q6AEIHjAA I went to the USPTO site and see that the catheter has a needle (so the device has two needles, not needle-free) in an accordion housing so it can be pushed forward to intrude into a space at the front of the catheter. I guess the sliding needle mechanism has a seal to close off catheter fluid flows while the blood is being drawn. Still, it seems that one would still have to draw a significant amount of fluid back to waste before catheter fluid was no longer significantly contaminating the blood draw. A minor improvement over old technology, if it is cost effective. https://www.ksl.com/?fm=most_popular&nid=148&s_cid=popular-7&sid=37339157  Needle-free blood draw technology to be tested at Utah hospitals | KSL.comA partnership between Intermountain Healthcare and San Francisco-based Velano Vascular is investigating new technology that could limit unnecessary needle pokes for hospital patients. source: https://www.linkedin.com/groups/78665/78665-6165318383488299009 Marked as spam

For a true home based AND 100% non-invasive technology, have a look at www.abogen.com
It is the world's first technology that allows for the use of saliva (yes saliva instead of blood) to do cell and protein based work (70% of what can be done with blood) ... not just DNA, blood proteins and blood cells work ... Let me know if interested. Marked as spam

The Baxter(r) Interlink product was first introduced in 1991 and marketed by the global leader is sharps products. Baxter also offers their Clearlink product for IV administration and blood collection. BD has numerous product offerings for needless blood collection (BD Q-Syte (TM) Luer Access Split Septum) as do many, many other companies in the medical device market segment.

Times have probably changed but when I was a Med Tech, we were not allowed to touch any lines. If we wanted an IV turned off so we could draw blood below it, we had to call a nurse. Certainly, we were not allowed to draw blood through any devices or catheters already attached to the patient. This would have done nothing for my lab and probably just made the nurses feel more overworked.
As I said, perhaps times have changed. We would have treasured a device like this rather than the rigmarole we went through. Marked as spam

Anyone else notice that is not actually blood in the article photo?

There are clear advantages to measuring substances in blood rather than interstitial fluid (as most of the glucose monitoring system do) or saliva. However, sampling blood involves the use of an invasive approach. Furthermore infrequent measurements miss important information. I have been working for many years on continuous blood sampling without blood withdrawal. It is invasive but leaves blood where it belongs, within the patient. Happy to discuss further.
