Title of the invention: Visualization apparatus for vein), which comprising: a near-infrared ray irradiating unit for irradiating near-infrared rays below the skin of target area; an infrared camera unit for photographing the target area; an image processing unit for receiving and processing image information of a portion below the skin of the target area taken by the infrared camera, and providing the processed image information to a display device; and a display device located near the target area and displaying image information provided by the image processing unit. The near-infrared ray irradiating unit has a predetermined inclination toward the target area direction so as to irradiate near-infrared rays to a portion below the skin of the target area through an outer skin of the target area. The near-infrared ray irradiating unit located inside of a barrier member, and the barrier member is used to prevent the infrared camera from capturing the near-infrared ray reflected from the outer skin surface of the target area.

According to the above previous technologies, since an operator may not only watch a near-infrared ray vein image through a display device but also directly see the skin of a target area, so that the venipuncture may be performed more accurately and intuitionally, and this technique may be applied to various operations which need visual checking of the veins in the skin. However, such technology can only display the position of the vein, it is not helpful for unskilled personnel in actual intravenous injections.

A real-time detection device of superficial vein has been disclosed in Korean Patent registration No. 2176196 (Registration date: Nov. 3, 2020. Title of the invention: Real-time detection device and method), which comprising: a near-infrared ray source module 100 for irradiate 800˜950 nm band near-infrared ray to the skin; a camera module 200 comprises one or more lenses 210 for picking up the image of subcutaneous vessels and a near-infrared ray (IR) image sensor 220 for imaging images obtained from the lenses 210; an image processing module 300 for image processing the subcutaneous vessels data transmitted from the camera 200; and a digital light processing module (DLP) 400 that outputs the vessel images outputted from the image processing module 300 to the photographed skin area.

Before the vessel image is detected, the DLP module irradiates a datum point or datum line to the patient's skin, and the image processing module performs the image process for the image obtained from the camera module based on the datum point or datum line, then the DLP module outputs the images based on the datum point or datum line.

According to the above mentioned former technology, since the vessel images are projected to the in-situ accurately and real-timely, so can reduce the medical accident and the side effects in the IV infusion process; and when it is necessary to avoid vessels to perform the injection, the vessels will not be damaged, thus the burden of medical personnel can be reduced during IV infusion or plastic surgery, and patients may be actively diagnosed and treated, and the patients will also have an increased sense of trust in medical personnel because of the accurate operation, but on the other hand, although the visibility of vein is very high, since the vein moves during operation, it is difficult to operate accurately.
