1. Rapidly establish intravenous access

Question: During emergency treatment (such as massive hemorrhage, shock, or cardiac arrest), rapid intravenous infusion or medication is required. However, the patient may experience vascular collapse due to dehydration, low blood pressure, or obesity, making it difficult to locate.

Function

Real-time display of subcutaneous veins (such as veins on the back of the hand and in front of the elbow) through infrared imaging can shorten the puncture time (studies show that it can reduce the number of attempts by 30-50%).

Avoid vascular damage or complications (such as hematoma) caused by repeated punctures.

Typical scenario

Emergency room rescue of patients with hemorrhagic shock.

Establish venous access for the wounded on the battlefield or at disaster sites.



2. Dealing with special patient groups

Children/Infants

Newborns have thin and fragile blood vessels. Vein-Finder can precisely locate them, reducing the pain of puncture (pediatric studies show a 40% increase in success rate).

Obese patients

The fat layer covers the veins, making traditional palpation difficult. The equipment can penetrate 10-15mm and clearly visualize the tissue.

Elderly/patients with chronic diseases

Long-term intravenous infusion can lead to vascular hardening or atrophy, and the device helps identify available venous segments.



3. Applications in harsh environments

Low light/Night rescue

When there is a power outage, in the wild or during night rescue, the device comes with its own light source and does not rely on external lighting (such as in earthquake-stricken areas or military operations).

Polluting the environment

Reduce operation time and lower exposure risks (such as in scenarios of chemical pollution or infectious diseases).



4. Reduce medical errors and the risk of infection

Function

Reduce needle contamination or occupational exposure of medical staff (such as HIV and hepatitis B viruses) caused by failed puncture.

Avoid phlebitis caused by repeated punctures, especially for emergency patients who need long-term intravenous infusion (such as those with sepsis).

Data support

An ICU study showed that the catheter-related infection rate decreased by 22% after the use of Vene-Finder.



5. Adaptation to special first aid scenarios

Burn patients

Skin damage makes it impossible to use a tourniquet. The device locates the remaining veins through non-contact imaging.

Hypothermia

When blood vessels constrict, infrared technology can still identify deep veins.

Diabetic emergency

1.Thickening of subcutaneous fat

• Deeper vein location: The subcutaneous fat layer of obese people is thicker, which may cause the veins to be covered by fat, making them deeper and difficult to accurately locate through visual observation or touch (palpation).
  
• Blurred touch: Adipose tissue weakens the elastic touch of veins finder, making it difficult for medical staff to determine the location and direction of veins through touch.
  
  2. Venous physiological changes
  
• Venous compression or concealment: Obesity may cause veins to be compressed or encapsulated by surrounding adipose tissue, further concealing their location.
  
• Circulatory problems: Obesity is often accompanied by diseases such as hypertension and diabetes, which may cause venous hardening, reduced elasticity or vasoconstriction, increasing the difficulty of puncture.
  
  3. Clinical operation challenges
  
• Reduced success rate: Research shows that the initial success rate of venipaspiration in obese patients is relatively low, and multiple attempts may be required.
  
• Enhanced reliance on technology: Medical staff may need to rely on tools (such as ultrasound-guided) or longer needles, or choose special puncture sites (such as the back of the hand or the veins in front of the elbow).
  
  4. Other influencing factors
  
• Skin condition: Obese individuals may develop skin wrinkles or edema, which further mask the veins.
  
• Patient position: Some positions (such as hanging arms) may help fill the veins, but obese individuals may have difficulty cooperating due to limited movement.
  
  Coping strategy
  
• Ultrasound-guided: Real-time ultrasound imaging can precisely locate deep veins.
  
• Hot compress or making a fist: Promote blood vessel dilation and increase venous visibility.
  
  Experienced operators: Skilled medical staff can increase the success rate through anatomical landmarks and experience.
  
  Summary
  

  Obesity does increase the difficulty of venipesis, but it can be effectively dealt with through technical means and clinical experience. This conclusion is clearly supported in both medical literature and clinical practice (such as the Journal of Emergency Medicine and Nursing Research).
