Abstract

The utility model relates to a portable dorsal hand vein observation instrument. The instrument consists of observation window, lens barrel, zoom knob, focus adjustment knob, top lighting module, housing, base with power supply, top light source switch, bottom light source switch, and bottom light source. The instrument of the invention utilizes the magnification characteristic of the microscope, enables medical personnel to observe clear veins on the back of the hand, facilitates venipuncture, improves the accuracy of venipuncture, and has a simple structure and low cost.

Description

[0001] Technical field: [0002] The invention relates to a portable dorsal hand vein observation instrument, which belongs to the technical field of medical instruments. [0003] Background technique: [0004] In the clinical diagnosis and treatment process, it is necessary to perform puncture operations such as intravenous injection, blood drawing and transfusion, and infusion. At this time, it is necessary to accurately find subcutaneous veins. The veins that are mainly studied at present are finger veins, palm veins and dorsal hand veins. Due to the small size of the finger vein, few blood vessels, and the thick palm fat layer of the palm vein, the dorsal vein of the hand is often chosen as the site of venipuncture. This area is larger and contains more veins. However, some patients have excess fat, darker skin, and thinner veins, making it difficult for medical staff to directly observe and distinguish with the naked eye. [0005] According to the position of the light s...
