As a medical staff, we may have such a problem. When injecting a patient's vein, we cannot find or locate the patient's blood vein. In this case, we will use a device for detecting veins - vein finder. portable vein finder for nurses is very helpful. Vein finder can eliminate the influence of risk factors, display veins accurately, clearly and in real time, help assist medical staff in the smooth progress of venipuncture, significantly improve the first success rate of venipuncture, and shorten venipuncture. time.
The vein imaging device uses the deoxygenated hemoglobin in the veins and the absorption of near-infrared light by different surrounding tissues to photoelectrically convert the information and process it through image processing, finally displaying the veins clearly on the screen.
Light Source: Vein finders use near-infrared light to illuminate the patient's skin. Near-infrared light is chosen because it penetrates the skin more deeply than visible light without causing harm.
Hemoglobin Detection: Hemoglobin in the blood absorbs near-infrared light differently than surrounding tissues. Vein finders exploit this property to create a contrast between veins filled with oxygenated blood and the surrounding tissue.
Image Processing: The device captures the reflected near-infrared light using sensors. These sensors then process the information to create a real-time image or map of the veins directly beneath the skin.
Display: The processed image is displayed on a screen or through eyepieces for the healthcare provider to see. This image typically highlights the veins as dark lines against a lighter background of the surrounding tissue.
Adjustments: Some vein finders allow adjustments for different skin tones and depths of veins. They may have settings to enhance contrast or to adjust the brightness and focus of the image.
Practical Use: Healthcare professionals use this real-time imaging to guide them in finding suitable veins for procedures like inserting IVs or drawing blood. It helps them avoid unnecessary punctures and reduces patient discomfort.
Advantages: Vein finders can be especially helpful in patients with difficult venous access, such as infants, elderly patients, or those with darker skin tones where veins may not be easily visible or palpable.
Overall, the portable vein finder for nurses is a valuable tool and relieves the pain of needle sticks for some elderly and children, eliminating the need for repeated needle sticks in different locations, allowing them to quickly and accurately locate veins, thereby improving patient satisfaction and clinical outcomes during vascular surgery.
