Intravascular Catheter Assembly

摘要

A peripheral intravascular catheter assembly comprising a tubular introducer needle and an adapter connected to the proximal end of the light guide. An introducer needle comprises a connection hub and a needle member. The needle member has a lumen, a distal end and a proximal end. The assembly may be further provided with a cannula tubing surrounding at least a portion of the needle member, with at least one light source and with an electronic module, configured to power the light source. The light guide has a distal end and a proximal end and extends along the lumen of the needle member. The adapter may be connected to the electronic module to the connection hub of the introducer needle so that light emitted by at least one light source is capable of entering the light guide, but blood flowing through the lumen of the needle member is prevented from contacting said light source.

1. A intravascular assembly for catheterization comprising:
a. an introducer needle comprising a connection hub and a needle member, wherein the needle member has a lumen, a distal end provided with a blood entry aperture, and a proximal end, and wherein the connection hub defines an inner chamber adapted to receive blood exiting from the proximal end of the needle member; b. a light guide having a distal end and a proximal end and extending along the lumen of the needle member, wherein the distal end of the light guide is arranged inside the lumen of the needle member; c. an adapter secured to the light guide, wherein the light guide is arranged to extend through the adapter; and d. at least one light source, wherein the adapter is provided with an interface for a light source, wherein the adapter is connected to the connection hub of the introducer needle, wherein the adapter is adapted to form a leak-proof barrier between blood within the inner chamber of the connection hub and the light source, wherein the proximal end of the light guide is optically coupled to the light source such that light emitted by the light source enters the light guide and is emitted by the distal end of the needle member, and wherein the light emitted from the distal end of the needle member has a total light intensity, and wherein at least 40% of the light emitted from the distal end of the needle member has a wavelength between 510 nm and 610 nm.
