    摘要： A transdermal introducer assembly is provided for quick and easy transcutaneous placement of a medical tube on a patient with reduced patient discomfort. The introducer assembly comprises a medical tube segment defining a hollow lumen extending between a distal end for placement into the subcutaneous tissue and a proximal end disposed outside the patient. The tube segment is assembled in side-by-side relation with a hollow introducer needle, and includes an elongated introducer thread at the distal end thereof folded back for slide-fit reception into the open distal end of the introducer needle. In use, the introducer needle is deployed to pierce the patient's skin at a selected placement site and to carry the tube segment to the desired transcutaneous position, after which the introducer needle can be withdrawn and slidably separated from the introducer thread to leave the tube segment and thread in place on the patient. A window is formed in the tube segment near the distal end thereof and, in a preferred form, exposes a transcutaneous sensor carried within the tube segment to patient body fluids.

    摘要： The invention provides methods and apparatus for detecting an analyte in blood. The apparatus is particularly suited for bringing a sensor into direct contact with blood in vivo. The apparatus comprises a sensor that detects the presence of an analyte and an assembly means. The assembly means has a sensor end, wherein the sensor end of the assembly means is affixed to the sensor, and the assembly means is adapted for coupling with a venous flow device. By coupling with a venous flow device, the assembly means brings the sensor into direct contact with blood flowing through the venous flow device. Examples of venous flow devices that bring the sensor into direct contact with the blood of a subject include, but are not limited to, intravenous catheters and external blood loops, such as are used in extra corporeal membrane oxygenation or hemodialysis.
