Embodiment Construction

[0047]Referring to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0048] Please refer to Fig. 1, the light source positioning display device 10 shown in the present invention is a device that uses LEDs as light sources or xenon bulbs or tungsten bulbs as light sources to locate superficial veins or specific tissues of the body, but uses red LEDs Light sources work best for injections, intravenous injections, blood vessel searches, and identification of different superficial tissue boundaries on the body. Especially as shown in Figure 5 and Figure 7, the size, bending state and bifurcation state of the subcutaneous tissue of the patient can be displayed in real time, which can help the medical staff to select the appropriate blood vessel position and carry out the operation with naked eyes. Vascular needle.

[0049] The top surface of the body of the light source positioning display device 10 is provided with a notch-sha...

Abstract

The disclosed method for seeking body veins utilizes a skin-clinging irradiation mode, wherein red light with 600-650nm of wave length is radiated to penetrate the fat tissue, which develops optical transmission, refraction and diffusion, as a result, the lateral diffusion illuminating effect can be produced, thus appreciable shadow can be formed by the blood vessels at the diffused illumination of the red light, thus the problem of difficult blood vessel positioning for patients having thick fat layer can be solved.

Description

technical field [0001] The invention relates to a method and a device for locating superficial veins or specific tissues of a body by using an LED light source, in particular to a method and a device for displaying blood vessel images with a red light source with a wavelength of 600-650nm. Background technique [0002] More than one hundred years ago, human medicine advanced to the point of using vascular puncture (Veinopuncture) to draw blood and transfuse or transfuse fluids such as blood and normal saline. But the key to the implementation of this medical technology is to try to find the blood vessels of the human body before puncturing the blood vessels for subsequent treatment. for diagnosis or treatment. Especially when the patient must be rescued, how to find the blood vessel on the patient's body quickly to set up the infusion route is just very important. [0003] The current methods of locating blood vessels clinically are as follows: [0004] 1. Visual method—f...
