  2. Venipuncture - Wikipedia

    en.wikipedia.org/wiki/Venipuncture

    An elastic tourniquet used to temporarily restrict blood flow. The tourniquet distends the veins, making them more palpable and visible.. There are many ways in which blood can be drawn from a vein, and the method used depends on the person's age, the equipment available, and the type of tests required.

  3. Near-infrared vein finder - Wikipedia

  8. Venous translucence - Wikipedia

    en.wikipedia.org/wiki/Venous_translucence

    The erythrocytes absorb more light because they are oxygenated. Considering that aspect, we can deduce that venous blood has a light absorption different from arterial blood (in which sanguine viscosity is greater, due to the higher concentration of CO 2. In that sense, venous blood has a greater ability to reflect light.

  9. Cephalic vein - Wikipedia

    en.wikipedia.org/wiki/Cephalic_vein

    The cephalic vein is often visible through the skin, and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. Permanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for intravenous access, as large bore cannula may be easily ...
