[0001] The utility model relates to the technical field of vein imaging instruments, in particular to a vein imaging instrument. Background Art

[0002] Veins are blood vessels that originate from capillaries and carry blood from various organs and tissues throughout the body back to the heart. Veins have thin walls, large lumens, low elasticity, low internal pressure, and slow blood flow. Currently, for young children, the elderly, obese patients, and those undergoing multiple chemotherapy treatments, venous identification during intravenous injections, punctures, or blood draws is challenging due to poor vascular elasticity, severe vascular collapse, reduced blood volume, or small vessels. This can easily lead to multiple injections due to inaccurate judgment by doctors and nurses, exacerbating patients' fear and physical pain. This can especially increase stress and pain in infants and the elderly, and even lead to medical disputes. Therefore, venous imaging devices are available on the market to facilitate the identification of suitable veins for injection.

[0043] It should be noted that, through the principle of light penetration and scattering, the penetration and scattering of light in the flesh is weakened, and the blood in the blood vessels has a high blood concentration in the blood vessel walls, which will clearly show the position and length of the veins. The present invention is based on the above principle and can display the position of veins that are not easy to see under the skin. It can improve the accuracy of vein positioning and the success rate of venipuncture, reduce patient pain and doctor-patient conflicts, and at the same time improve the work efficiency of medical staff, and is highly practical.

[0044] like Figures 1 to 6 As shown, the working principle of the utility model is as follows:

[0045] During use, the power switch button 24 is pressed to turn on the power. At this time, the lamp beads 13 on the lamp board 9 will not emit light. When the palm or the sole of the foot needs to find the position of the vein and touches the upper end of the light mirror 6, the touch sensor 7 detects the touch action and transmits a signal to the PCB board 23 through the touch panel 11. The PCB board 23 performs corresponding operations according to the signal, so that the lamp beads 13 emit light and the veins are displayed on the back of the hand or the back of the foot after the light penetrates. When the palm or the sole of the foot leaves the upper end of the light mirror 6, the lamp beads 13 also stop emitting light accordingly, which can avoid the light emitted by the lamp beads 13 from irritating the eyes, which is safe and improves the user experience.

[0046] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above.
