1.The application of Doppler ultrasound technology in venous localization

A research team from the Georgia Institute of Technology in the United States has developed a low-cost handheld device that uses Doppler ultrasound technology to quickly locate veins. This device distinguishes arteries from veins by emitting ultrasonic beams and analyzing blood flow reflection signals, and guides punctures in real time. It is particularly suitable for situations where veins are difficult to locate, such as in patients with trauma or burns. This technology has entered the human testing stage and is expected to achieve a portable design the size of a pen in the future.



2. Market and Technological Trends of Projection Vein Detectors

Technical classification: Laser, infrared and ultrasonic are the mainstream technologies. Laser technology has high precision and is suitable for intravenous injection and sclerotherapy. Infrared technology is low in cost and portable, and is often used for first aid. Ultrasound is widely used in vascular surgery due to its non-invasiveness and deep vein imaging ability.

Market-driven: The rising incidence of vascular diseases (such as varicose veins and deep vein thrombosis) and the increasing demand for minimally invasive surgeries have driven market development. By 2032, the global market size is expected to reach 10.8 billion US dollars, with a compound annual growth rate of 9.05%.



3. Technological breakthroughs in Infrared vein detectors and their impact on the supply chain

Technological progress: Near-infrared (NIR) imaging technology has significantly enhanced the accuracy of vein visualization, especially suitable for obese or dark-skinned patients. The portability of handheld devices makes them applicable in home care and remote areas.

Trade policy impact: The additional tariffs imposed by the United States have affected the technological flow and supply chain layout of the infrared vein detector industry, prompting Chinese enterprises to accelerate localized research and development, and at the same time promoting international enterprises to adjust their global value chains.



4. Vein recognition and biometric technology

The BK series of dorsal hand vein recognition systems developed by NEXTERN of South Korea and the palm vein imaging technology of Fujitsu of Japan both capture the distribution of subcutaneous veins through infrared rays and are applied in the field of identity authentication. Research from the University of Tennessee in the United States utilized CCD cameras combined with infrared filters to capture vein images, exploring their potential in the medical and security fields.



5. Tip catheter positioning technology (such as the Sherlock 3CG system)

The Sherlock 3CG system recommended by the American Society of Intravenous Infusion Nurses (INS) combines magnetic tracking and ultrasound guidance to achieve real-time positioning of PICC catheter insertion. This technology precisely determines the position of the catheter tip through changes in electrocardiogram signals (such as color changes in P-waves), reducing X-ray exposure and the risk of complications. It has been clinically promoted abroad.



6. Non-invasive central venous pressure (CVP) measurement technology

A research team from Massachusetts General Hospital in the United States has developed quantitative compression ultrasound (QCU) technology to non-invastively estimate CVP by measuring the collapse force of the internal jugular vein. Studies have shown that the accuracy of QCU is significantly higher than that of the traditional jugular pulse height measurement method, providing a new tool for the monitoring of diseases such as heart failure.



7. Clinical Application and Market Pattern of Venous Viewing Devices

The main enterprises: AccuVein (handheld infrared device), VeinViewer (high-precision projection technology), BD (medical equipment giant), etc. dominate the market. AccuVein’s products have become industry benchmarks due to their portability and real-time imaging capabilities.

Application scenarios: Hospitals (blood drawing, intravenous injection), clinics (minimally invasive surgery), and blood donation centers (efficient blood collection) are the main application fields, with North America and Europe occupying the largest market share.



8. Neuroscience correlation research of venous imaging

The study published in "Nature Communications" utilized the displacematic MRI (DiSpect) technique to reveal the hemodynamic changes of the cerebral venous system during neural activation. This technology not only enhances the resolution of venous imaging, but also provides a new perspective for the diagnosis of brain diseases such as stroke and multiple sclerosis.

To make veins show quickly for an injection, consider the following safe and effective methods, along with important precautions:



1.  Hydration

• Action: Drink 1-2 glasses of water 30-60 minutes beforehand.  Hydration increases blood volume, making veins more prominent.
  
• Note: Avoid excessive water intake, which can dilute electrolytes.
  
  2.  Apply Warmth
  
• Action: Place a warm compress or heating pad (not too hot) on the area for 5-10 minutes.  Heat dilates veins by increasing blood flow.
  
• Caution: Ensure the temperature is comfortable to prevent burns.
  
  3.  Use Gravity
  
• Action: Let the arm hang down below heart level for 1-2 minutes.  Gravity pools blood in the veins, enhancing visibility.
  
  4.  Exercise the Limb
  
• Action:Open and close your fist repeatedly or squeeze a stress ball for 30-60 seconds.  This engages muscles, pushing blood into superficial veins.
  
  5.  Gentle Tourniquet
  
• Action: Use a soft strap or blood pressure cuff (inflated to low pressure) around the upper arm.  This temporarily restricts venous return, causing veins to bulge.
  
• Caution: Do not leave on longer than 2-3 minutes to avoid nerve damage or ischemia.
  
  6.  Stay Calm
  
• Action: Practice deep breathing to reduce anxiety.  Stress causes vasoconstriction, hiding veins.
  
  7.  Visual Aids
  
• Action:Shine a flashlight under the arm in a dark room;  veins may cast shadows.  Alternatively, gently tap the skin to irritate the vein (avoid aggressive tapping).
  
  8.  Avoid Stimulants
  
• Action:Refrain from caffeine, nicotine, or cold environments for 1-2 hours before, as these constrict blood vessels.
  
  Additional Tips:
  
• Vein Selection: Forearm veins (e.g., cephalic or basilic) are often easier to access than hand veins.
  

  - Professional Help:If veins remain elusive, seek a trained practitioner to avoid complications like bruising or phlebitis.
