3" LED Portable Vein Finder Used in Veinpuncture with 10 Kinds of Color Display

Definition

Venipuncture is a commonly used medical method. This blood vessel imaging device can make it easier for doctors and nurses to find veins, improve the success rate of venipuncture in children and obese people, and reduce the pain caused by the failure of venipuncture.

Working Principle

Vein finder Aurora 100 is developed on the basis of the specific absorption spectrum of deoxyhemoglobin. When infrared light irradiates human tissues, deoxyhemoglobin in vein has more obvious absorption effect than surrounding tissues, which leads to less reflection of infrared light. CMOS camera is used to collect infrared image of subcutaneous veins. After photoelectric conversion and software filtering, enhancement and segmentation of the image, the vein image which can be distinguished by naked eyes is generated. Shadow-light path will return the processed venogram to the image acquisition point of skin surface in the form of visible light, so that the venous information of skin surface can be more clearly displayed, thus effectively assisting venous localization.

Based on the above principle, the blood vessel imaging system realizes the display of subcutaneous veins which are difficult to see. It can be used to assist the localization and display of superficial blood vessels in dorsum of hand, dorsum of foot, elbow bend and scalp.

Application Scope

The vein finder is mainly used for the observation and search of superficial subcutaneous vessels in venipuncture departments and varicose operation rooms, and assists medical staff in venipuncture operations such as venipuncture examination, transfusion and blood drawing.
