Drawing blood should be a something commonly done procedure. Unfortunately difficulties can be common either in the old, who may have a damaged/a broken-into vasculature, or in children who are literally scared out of their minds. A startup based in Mountain View, California aims to replace your friendly phlebotomist with a robot. If this new device can gain patient confidence and perform well under ideal conditions, maybe it can also be of service in more demanding conditions also.

The robot phlebotomist, known as the Veebot, looks like it is a specially changed version of one of Epson’s standard a person who misleads and tricks people for his or her own benefit arms. Epson manufactures some of the fastest, and in a lucky way, most very close to the truth or true number multi-axis arms in the business. The head used on the Veebot appears to be custom changed to fit provide the added/more elements needed to achieve through skill the ideal stick. Human technicians definitely have more flexibility in changing to make better/changing to fit new conditions the angle and force applied when trying to penetrate the near side of vein without going clean through it. What the robot has going for it, though, is better tools for identifying the best place to poke/punch you in the first place.

To select the right spot, the Veebot uses near-infrared lighting up/education and computer vision software to identify veins below the skin. The imaging works well across a wide range of what colors skin, hair, eyes, etc. concentrations and skin tones gave/given there is not too much below the skin fat to scatter the light. An inflatable cuff restricts blood flow and pump up the veins, while the Veebot also checks that their is good enough flow using ultrasound. There are not many details here but one might guess that ultrasonic Doppler imaging might be used to guess a number flow speed gave/given that the cuff pressure is controlled in the same way/in that way.


For now, the robot has a success rate of 83%, which leaves some room for improvement. The development team plans to enter scientific fact-finding experiments when they get a rate above 90%, although that is still well below what patients expect from a human technician. Once perfected though, there are a lot of something commonly done sampling procedures that could benefit from this technology. Related to the lower back punctures are commonly performed to take off a bit of brain and spinal cord fluid CSF to either check for infection, or to deliver medicine or pain-killer that otherwise would not pass the border between the blood and the brain that can be hard to get through. The failure rate is fairly high for first pass penetrations, and when CSF leaks out without any advance planning, a headache of giant size can be expected. Automating this procedure would take out some of the guesswork and provide better comfort for the patient.
