Vascular Access Detection Device and Method

摘要

A vascular access detection device and method for ensuring the proper insertion of a needle into a target is disclosed. A light source generates a beam of light which is directed along the needle's longitudinal axis so that said beam of light passes though the hollow shaft of the needle. The needle may be guided to a target inside a patient's body. Reflection and scattering of light by portions of the patient's body may be monitored to assist in determining when the target inside of the patient's body has been pierced by the needle.

主权项

1. A vascular access detection device for ensuring the proper insertion of a needle with a hollow shaft held in a needle hub, comprising:
a light source that generates a beam of light, wherein said light source has a distal end, said distal end defining an aperture through which said beam of light passes; and an interface bridge that protects said light source from contamination comprising a lens that allows light to pass through said interface bridge, wherein said interface bridge is adapted to operatively engage said distal end of said light source and operatively engage the needle hub, wherein said interface bridge aligns said light source and the needle along the needle's longitudinal axis so that said beam of light will pass though the hollow shaft of the needle so as to be detectable.
