Description

Arterial blood vessel imaging device and blood vessel imaging instrument

technical field

The invention relates to the technical field of medical equipment, in particular to an arterial vessel imaging device and a blood vessel imaging instrument.

Background technique

Arterial blood collection is one of the daily nursing operations of clinical medical staff, and it is also one of the most troublesome operations for ICU and respiratory medicine medical staff. Clinically, junior nurses like to choose the femoral artery because the femoral artery is easy to reach, but if the position is slightly deviated, blood will be drawn from the femoral vein; senior nurses often prefer the dorsalis pedis artery, because the movement of the dorsum of the foot is very important to the patient. The effect of the needle is not as great as that of the wrist; the brachial artery cannot be used in pediatric patients due to the lack of lateral circulation. As for the more risky arterial puncture, symptoms such as hemorrhage, hematoma, infection, and complications are prone to occur, which not only aggravates the suffering of patients, but also easily causes disputes between doctors and patients.

In recent years, infrared imaging systems have been widely used in industry, transportation, military and medical fields. They are one of the important means of detection, management, monitoring and identification, and have greatly improved work efficiency and intelligence. Generally speaking, an infrared imaging system consists of the following parts: light source, target, lens group, CCD, computer. Usually, an infrared imaging system needs to be equipped with an image processing function to store, analyze, and identify the image formed by the target object.

However, most of the infrared vascular imaging technologies currently on the market are aimed at superficial venous blood vessels. There are no effective methods and mature solutions for deep arterial blood vessel imaging technologies and devices. Most of them are still detected by hand. Determining the position of the artery by experience and other means cannot meet the needs of medical staff.
