1.Venipuncture assistance

Conventional venous puncture、Increase the success rate of puncture

The success rate of traditional puncture (relying on palpation and visual inspection) is approximately 60-75%, while it can be increased to 85-95% after using a vein finder, especially for patients with higher difficulty levels (such as children, the elderly, and obese individuals), the effect is particularly remarkable.

Typical scenarios: blood drawing, intravenous infusion, and placement of indwelling needles.

Reduce complications: Lower the risk of hematoma, nerve damage and infection caused by repeated punctures.

Studies show that after using a vein finder, piercing-related complications are reduced by approximately 40%.

Special patient groups

Pediatric patient

Children’s veins are small and mobile, and traditional puncture may require multiple attempts. Vein finder (can clearly display vein branches and reduce the pain of children patients.)

Obese patients

When the subcutaneous fat layer is relatively thick (>3cm), near-infrared technology can penetrate the fat to locate deep veins (the success rate of traditional methods is only 50%).

For patients in shock or dehydration: When blood vessels collapse, the vein finder can identify veins that are invisible to the naked eye and quickly establish an emergency access.



2. Navigation for surgery and interventional therapy

Vascular surgery assistance

PICC (Peripherally Inserted Central Catheter) :

Accurately select the appropriate vein (such as the precious vein) to avoid mistakenly penetrating arteries or nerves, and the success rate has increased from 75% to over 90%.

Establishment of hemodialysis access: Locate well-functioning veins and prolong the service life of fistulas.

Patients with tumors and undergoing chemotherapy

Protecting vascular resources: Chemotherapy drugs are prone to cause phlebitis. Precise puncture can reduce vascular damage.



3. Emergency and Intensive Care

Rapid establishment of intravenous access: In emergency scenarios (such as cardiopulmonary resuscitation, massive hemorrhage), shorten the puncture time to within one minute.

Difficult intravenous treatment: For burn patients (with skin damage) or those with edema, avoid blind puncture.



4. Management of chronic venous diseases

Varicose vein screening: Evaluate the function of venous valves through dynamic imaging to assist in early diagnosis.

Deep vein thrombosis (DVT) assessment: Some studies have explored the possibility of using a vein finder combined with ultrasound to detect thrombosis (not yet widespread).



5. Special scenario applications

Military and disaster medicine

Battlefield first aid: Portable devices can quickly locate veins in low-light or harsh environments.

Veterinary field

Pet medical care: It is used for venipuncture of animals such as dogs and cats, especially for small dogs or dehydrated animals, with remarkable effects.



6. Medical Education and Quality Control

Training and teaching: Demonstrate the anatomical structure of veins through real-time imaging to reduce the practice mistakes of beginners on real patients.

Operation Record and analysis: Store puncture data for review to enhance the technical proficiency of the team.



Clinical advantages and limitations

Advantages

Non-invasive, real-time imaging

Reduce medical costs (decrease waste of consumables and repetitive operations)

Improve patient experience (reduce pain and anxiety)

Limitations: Technical limitations: The efficacy may decline for patients with extreme obesity (fat layer >5cm) or severe circulatory disorders.



The future direction of clinical development

Fusion with ultrasound: Enhance the imaging capability of deep veins and microvessels.

AI prediction system: Automatically recommend the best puncture path.

Low-cost popularization: Develop a simple version suitable for primary healthcare.

Vein finder has gradually evolved from an "optional tool" to a "clinical necessity", especially showing significant value in enhancing medical safety and efficiency. However, its full-scale popularization still needs to address issues of cost and technical compatibility.

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.
