Reflective ultra-portable human superficial vein imaging instrument

Abstract

The invention discloses a reflection-type ultra-portable human body superficial venous vessel imaging apparatus, which comprises a shell, control switch buttons arranged on the shell and a control circuit board which is arranged in the shell, wherein the shell comprises an upper shell body and a lower cover plate; the control circuit board comprises a PCB board as well as a power module, a central control module, a driving amplifying module and a plurality of three-color LED lamps on the PCB board; the power module is electrically connected to the central control module and the driving amplifying module; the central control module is electrically connected to the control switch button; the driving amplifying module is electrically connected to the three-color LED lamps; each three-color LED lamp is composed of a red light source, a yellow light source and a blue light source; the upper shell body, the control circuit board and the lower cover plate are provided with corresponding observation windows; the plurality of three-color LED lamps are distributed along the periphery of the observation window in the upper shell body at intervals; and the parts, corresponding to the three-color LED lamps, of the lower cover plate are provided with dodging thin films. With the application of the imaging apparatus provided by the invention, venous vessels are highlighted, and meanwhile, depth information of the vessels is displayed.

Description

technical field [0001] The invention belongs to the field of biomedical electronic engineering, in particular to a reflective ultra-portable superficial human body vein and blood vessel imaging instrument. Background technique [0002] In the process of clinical treatment and inspection, venipuncture is an important and commonly used medical technology, and venipuncture can be used for blood collection, blood transfusion and infusion of patients. In the traditional venipuncture operation, the medical personnel need to find the superficial vein of the patient's skin first, and then accurately locate the target blood vessel before inserting the needle into the blood vessel. Therefore, identifying and locating target venous vessels plays a particularly important role in the venipuncture process. In the actual clinical operation process, due to factors such as age, obesity, dark skin color, anemia, low blood pressure and ambient light, it is difficult to find, identify and loca...

Problems solved by technology

This type of vein imaging device has a relatively simple structure, small volume, general vein imaging effect, and requires a high-power light source. During use, the temperature is too high, and temperature control measures need to be taken. At the same time, for the inner part of the arm, Venous vascular transmission imaging is more difficult for adults with thick palms, obese people, and patients with dark skin.
