1-Near-Infrared Vein Finders

This is the most intuitive tool for dealing with superficial veins (within 10mm subcutaneous), such as Vein Finder

Working principle: Hemoglobin in the blood absorbs near-infrared light, while the surrounding tissues (including subcutaneous fat and scar tissue) reflect the light. After the instrument captures this information, it will project the shape of the veins back to the skin surface in real time with dark lines or bright colors.



How to avoid scars: Scar tissue itself lacks normal capillaries and venous networks, so under an imager, the scar area usually appears as a “blank” or blocked zone.

The operator can hold the imaging instrument to scan around the scar and observe the course of the veins (vascular tree).

Search for available veins: Follow the dark vascular lines displayed by the imaging instrument and trace upstream (proximal end) or downstream (distal end) to find a section of vein that avoids the scar edge, has a clear and straight line, and serves as the puncture point.



2-Ultrasonic guidance technology

When the scar area is large or the superficial veins have been exhausted and it is necessary to find deeper veins, ultrasound is the “gold standard”.

Working principle: Utilize high-frequency sound waves to penetrate tissues. Liquids (such as blood in veins) appear black (anechoic) under ultrasound, while dense tissues (such as scars and muscle fascia) appear bright white (hyperechoic).



How to avoid scars

Scar tissue is composed of dense fibrous connective tissue. On an ultrasound screen, it appears as a particularly bright area. Due to its high density, it may produce acoustic shadows at the bottom of the image, blocking the view.

The operator places the ultrasound probe (usually a high-frequency linear array probe) on the normal skin around the scar for cross-sectional scanning.

1-Overcome the limitations of light and hardware in the home environment
Uncontrollable lighting

: Hospital blood collection rooms usually have bright, shadowless professional lighting, while the light in patients’ homes is often dim, warm-toned, and even small, making it difficult for nurses to clearly see the blood vessels with their naked eyes.



The assistance of the imaging device: The portable venous imaging device comes with its own light source and can emit near-infrared light of a specific wavelength, completely unaffected by the ambient light in the home. It can provide nurses with a high-contrast “navigation map” of blood vessels in a dim bedroom or beside a bed.



2.-Overcome the “difficult blood vessels” and increase the rate of incisive response

Patients who need home blood collection are often vulnerable groups who have difficulty going to the hospital, and their vascular conditions are usually poor.

Elderly patients: The blood vessel walls are fragile, have poor elasticity, and are prone to sliding or collapsing.

Children/infants: They have small blood vessels, thick fat layers, and are prone to crying and being uncooperative.

Patients with chronic diseases or severe conditions: such as those who have been bedridden for a long time, have edema, are obese, or frequently undergo chemotherapy (for arteriosclerosis).



The assistance of imaging devices: Nurses no longer need to blindly “explore” or repeatedly touch based solely on experience. The imaging device can directly display the direction, thickness, branches and even the position of the valves of veins, helping nurses precisely select the straightest and healthiest blood vessels for puncture, significantly increasing the success rate of “puncturing with a single needle”.



3-Alleviate the anxiety of patients and their families and build trust between doctors and patients

Psychological stress: When invasive procedures are performed in a non-medical environment (at home), patients and their accompanying family members often become even more nervous. Once the first injection fails, the family members’ emotions can easily get agitated, leading to complaints.

The assistance of imaging devices: When patients and their families witness high-tech equipment clearly projecting originally invisible blood vessels onto the skin, it will greatly enhance their trust in the professionalism of nurses. The "visualized" process makes family members feel at ease and effectively reduces the cost of doctor-patient communication and the potential risk of friction.

: When encountering puncture difficulties in the hospital, nurses can call for assistance from senior colleagues at any time. However, home blood collection is usually done by a single person, and the psychological pressure is huge when encountering difficult blood vessels.

The assistance of the imaging instrument: The device is compact in size (usually about the size of a flashlight), can be handheld or used with a portable stand, which greatly enhances the operational confidence of the nurses on duty. Quickly locating blood vessels not only reduces the psychological burden on nurses but also shortens the service time for a single blood collection, thereby enhancing the overall outpatient efficiency of nurses within a day.

1. Bridging the "technical gap" of grassroots nurses

In remote areas of developing countries, there is often a severe shortage of experienced intravenous therapy nurses, and the turnover rate of primary medical staff is high. Many newly graduated or insufficiently trained novices have an extremely high failure rate in puncture when dealing with difficult blood vessels. The imaging device can directly "draw" the vascular routes on the skin, which is a typical "foolproof auxiliary tool", greatly lowering the technical threshold of puncture. This is an excellent selling point that can directly reduce medical disputes for local private clinic owners or distributors in lower-tier markets.

2. Addressing the challenges of tropical diseases and deep skin tone

Dark skin puncture: In some parts of Africa or South Asia, dark skin can increase the difficulty of visually locating superficial veins. Near-infrared technology, based on the principle that blood absorbs light, has extremely low sensitivity to skin color and can clearly display the venous network of patients with dark skin tones.

Emergency treatment for tropical infectious diseases: Dengue fever, cholera, malaria and other diseases frequently occur in these areas. Patients often suffer from severe dehydration, shock or fever, which can cause blood vessels to shrivel and collapse. The imaging device can help village doctors quickly locate venous channels for fluid replacement in such highly challenging emergency situations.

3. Perfectly fit the "mobile medical tour" and power shortage environment

Primary healthcare in emerging markets relies heavily on mobile medical vehicles, rural medical teams or temporary medical camps set up by international non-governmental organizations . The portable venous imaging device is compact and comes with a large-capacity rechargeable battery, completely independent of a stable power grid. In remote villages with unstable power supply, this ready-to-use device can be regarded as a practical wonder.

4. Reduce the waste of consumables and the risk of needle prick infection

The budgets of primary clinics in developing countries are usually very tight. Repeated blind punctures not only waste precious consumables such as indwelling needles and blood collection needles, but more fatal is that in areas with a high incidence of blood-borne infectious diseases such as AIDS and hepatitis B, blind punctures greatly increase the probability of medical staff suffering from needle-puncture injuries. Improving the rate of "hitting the nail on the head" is directly helping local hospitals save money and lives.

1. Main detection depth

General depth: Most devices can detect veins 0.2 to 1.0cm beneath the skin, but the actual effective imaging range is usually concentrated on the shallower veins under the skin (0.2 to 1.0 cm).

Best effect: For clearly visible superficial veins (such as the back of the hand and forearm), the imaging effect is the best.



2. Key influencing factors

Skin condition

Skin color, fat thickness, edema or scar tissue can reduce penetration.

Patients with obesity or edema may have limited depth.

Equipment performance

The wavelength of the light source (usually near-infrared, approximately 750 to 980 nm) affects the tissue penetration.

The imaging algorithm and sensor sensitivity determine the ability to restore details.

Venous characteristics:

There are significant differences in vein diameter, blood filling degree and depth.

Deep veins (such as the femoral vein in obese patients) may not be clearly displayed.



3. Technical limitations

Non-penetrating deep blood vessels: Unable to detect arteries or visceral blood vessels, mainly used for superficial vein finder localization (such as infusion and blood drawing).

Auxiliary rather than substitute: It cannot completely replace deep imaging technologies such as ultrasound.



4. Common application scenarios

Patients with difficulty in venipuncture (children, the elderly, obese individuals).

Patients with arteriosclerosis or hidden veins caused by long-term intravenous infusion or chemotherapy.

The following differences also need to be considered when making a choice:
1. Display mode

Direct vision/projection: Project the vascular image directly onto the patient’s skin. The advantage is that the operator does not need to shift their gaze and their hands and eyes are in perfect coordination. The drawback is that the projection may deform due to the curved surface of the skin.

Screen display type: View vascular images on an independent display screen. The advantage is that the image is clear and stable, and can be viewed by multiple people. The drawback is that the operator needs to switch the line of sight between the patient’s skin and the screen.



2. Portability and form

Handheld portable: The most common, it looks like a large flashlight or probe, is flexible and convenient, and can be used beside the bed.

Desktop/floor-standing: Usually more powerful in function, not easy to move, and often used in fixed departments.

Head-mounted/wearable: Free up hands, but still in the development stage and not widely used.



3. Functional differences

Simple positioning vs. navigation guidance

Positioning type: Only displays the location and direction of blood vessels. Most infrared devices fall into this category.

Navigation-guided type: It can not only display blood vessels but also provide real-time guidance on the insertion path and depth of the puncture needle through technologies such as laser indication and puncture needle tracking. Most high-end ultrasonic devices are equipped with this function.

Vascular recognition algorithm: Smart devices can automatically identify and outline the center line of blood vessels through algorithms, and even assess the suitability of blood vessels, rather than merely displaying an image.



4. Cost and Maintenance

Near-infrared equipment: The purchase cost is relatively low, almost no consumables are required, and maintenance is simple.

Ultrasonic equipment: The purchase cost is high, it requires consumables such as coupling agents, and the maintenance and professional training costs are also high.



How to choose?

For routine clinical needs (such as outpatient infusion rooms) : High-quality near-infrared light vein finder are the most cost-effective choice and can solve the puncture problems of most patients.



For patients with difficult puncture (such as ICU patients, the elderly, those undergoing chemotherapy for tumors, and obese patients) : Portable ultrasound vein finder are more effective tools because they can “see” deep blood vessels and have a higher success rate.



For the establishment of medium to long-term vascular access: Ultrasound equipment is the gold standard, and even an essential tool, as it can assess vascular conditions, prevent accidental arterial puncture, and guide catheter placement in real time.

This is where Vein Visualization Technology (Vein Finders) is changing the game. Beyond just locating veins, these devices are becoming essential tools for psychological comfort and patient retention.

1️⃣ The Science of Fear: Why “First-Stick Success” Matters

Anxiety often stems from the fear of pain and the “unknown.” Patients are terrified of the nurse “fishing” for a vein.

The Stat: Studies show that multiple insertion attempts significantly increase patient distress.

The Solution: Vein finders utilize Near-Infrared (NIR) technology to project a real-time map of the vasculature on the skin. This dramatically increases the First-Stick Success Rate, assuring the patient that the procedure will be quick and accurate.

1) Traditional Screening Methods and Their Limitations

Traditionally, the screening and staging of DR Mainly relied on color fundus photography to observe two-dimensional surface lesions such as retinal microaneurysms, hemorrhage and exudation. However, this method has limitations:

Strong subjectivity: Relying on the doctor’s experience.

Inability to observe deep structures: It is impossible to quantitatively assess the early structural damage of the retina, especially the early morphology of diabetic macular edema (DME).



2) The core role of OCT in the early detection of DR

OCT is a non-contact and non-invasive cross-sectional imaging technique, similar to “optical biopsy”, which can provide micrometer-resolution images of each layer of the retina. Its application in early DR Is mainly reflected in the following aspects:

1. Detect subclinical diabetic macular edema

Key finding: OCT can detect before clinically visible retinal thickening or hard exudation (visible in traditional fundus photography) occurs in patients:

A slight thickening of the inner layer of the retina.

Early and local damage to the outer structures of the retina (such as the ellipsoid zone and the external membrane).

Tiny cystoid hyporeflex cavities (early cystoid edema).
