BLOOD VESSEL SEEKING METHOD AND VEIN SEEKING DEVICE

摘要

The invention relates to a blood vessel seeking method and a vein seeking device, wherein said blood vessel seeking method includes step hereinafter: (a) closing at least one solid state lighting source with the wavelength between 550 and 650nm and at least one near touching device to the tissue (4); (b) said near touching device induces the tissue signal; (c) said near touching device touches off said solid state lighting source to transmit a beam; and (d) said solid state lighting source transmits the beam to irradiate the tissue (4). Said vein seeking device includes: a main body (2) which is provided projectingly a solid state lighting source with the wavelength between 550 and 650nm on its surface, the length which said solid state lighting source project said main body (2) surface is between 3 and 30mm, and its diameter is between 3 and 15mm. Said vein seeking device may further include: a main body (2); at least one solid state lighting source, which is provided by the main body (2); at least one near touching device, which is provided by said main body (2), said near touching device is connected to said solid state lighting source.
