visual venipuncture device

Abstract

The invention relates to a visualized vein puncturing instrument. A light filter is connected with a camera, a lamp shade is connected with a transverse beam through a sliding part, a projector in the lamp shade is arranged at one end of the transverse beam through a screw, the other end of the transverse beam is connected with a rotary shaft, one end of a vertical column is connected with the rotary shaft, the other end of the vertical column is connected with a base, and a lower light source, a heat radiating hole, a light source adjusting switch, a soft-off machine, a mode switching switch, a lower light source switch, a power source switch and a power line charging hole are respectively arranged on the base. The visualized vein puncturing instrument has the advantages that a collection light path of using an infrared camera to capture vein images in real time is designed according to the infrared imaging principle; a method of combining transmission and reflection infrared light sources is used for detecting the information of veins with different depths; stable, continuous and clear vein images are obtained, the real-time enhanced vein images are projected to the skin surface by an image projection light path, the vein images can be developed in real time, and the puncturing operation of medical staff is greatly and conveniently carried out.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a visual venipuncture instrument capable of rapidly and accurately displaying veins in situ and assisting venipuncture. Background technique [0002] Intravenous injection, intravenous blood collection and blood transfusion are one of the important measures for rescuing and treating patients, and are also a very common medical method. However, for some patients with inconspicuous veins, such as: obese patients have thicker subcutaneous fat and deeper veins, the tourniquet must be tied tightly during venipuncture; patients with edema are difficult to see and touch due to tissue edema. After tightening the tourniquet to the blood vessel, you need to press the puncture site with your fingers, and the action must be quite fast, otherwise the local edema will make the vein difficult to see; young and uncooperative children often need a lot of experience when venipuncture.

Problems solved by technology

However, for some patients with inconspicuous veins, such as: obese patients have thicker subcutaneous fat and deeper veins, the tourniquet must be tied tightly during venipuncture; patients with edema are difficult to see and touch due to tissue edema. After tightening the tourniquet to the blood vessel, you need to press the puncture site with your fingers, and the action must be quite fast, otherwise the local edema will make the vein difficult to see; young and uncooperative children often need a lot of experience when venipuncture. Nurses are abundant, and at least 2 tourniquets must be tied; patients with peripheral circulatory failure, especially those with hemorrhagic shock, have submerged superficial veins and collapsed blood vessels, making venipuncture very difficult

This situation has caused great distress to medical staff, often leading to misoperation or repeated operations, which will not only cause disputes between doctors and patients, but even delay the timing of diagnosis and treatment.
