Description

Blood vessel detector

Technical Field

The utility model relates to the technical field of medical equipment, specifically a blood vessel detector.

Background

The near infrared projection device appearing in recent years is the visible radiography of the vein vessels. The technology can accurately display the subcutaneous blood vessel, and meanwhile, the influence of three-dimensional depth is not required to be considered for imaging the blood vessel. Meanwhile, the safe near infrared light avoids the inconvenience that the patient is exposed to the skin.

The principle of operation of such a device is that the area to be imaged is first illuminated with near infrared light, and since the absorption of near infrared light by the blood can at the same time penetrate the epidermis, the position of the veins can be located according to the absorption of reflected light. (Note: veins are generally subcutaneous, while arteries are deeper). And finally, processing the detected information and projecting the processed information to a previously irradiated area through a projector so as to display the position of the blood vessel. The whole process is very similar to projector-mapping which is commonly used in the visual field.

The vein imaging instrument can realize real image output and digital real-time radiography through active blood vessel image navigation (AVIN). By harmless near infrared light, the real-time navigation of the system can project dynamic digital images of vein vessels to the surface of skin in real time, accurately and intuitively. After the vein imaging instrument irradiates, the distribution of veins can be clearly displayed on the surface of the skin, and medical staff can be helped to find the best intravenous injection position, so that potential acupuncture complications are avoided. By utilizing the high-definition image technology, the vein imaging instrument is the only instrument which can clearly observe veins in the whole intravenous injection process, including before injection, during injection and after the injection is finished, and the instrument can benefit all patients.
