1. Patients with difficulty in venipuncture
Typical population
Obese people (with thick subcutaneous fat layers and deeply hidden veins).
Infants and children (with thin blood vessels and low cooperation).
The elderly (with poor vascular elasticity and prone to rolling).
Patients who have received long-term intravenous infusion or chemotherapy (with hardened blood vessels and many scars).
Scene value
Reduce the number of repeated punctures (for example, from an average of 3 to 1) to lower the patient’s pain and the risk of complications (such as hematoma).
2. People with dark skin
Problem: Traditional visual/touch methods have difficulty locating veins in dark skin.
Technical adaptation
Choose multi-wavelength Vein Finder (for example, 850nm infrared light has better penetration).
Contrast adjustment function (such as the “Dark Skin Mode” of VeinViewer).
3. Emergency and critically ill patients
Applicable scenarios
Patients with shock/dehydration (vascular collapse).
Rescue for massive hemorrhage (rapid establishment of intravenous access is required).
Case: The emergency department uses AR projection devices (such as AccuVein) to locate the external jugular vein within 5 seconds.
4. Patients with chronic diseases and special treatment needs
Diabetes: Monitor the condition of blood vessels on the back of the hand/foot to prevent ulcers.
Hemodialysis: Protect the fistula and prevent accidental puncture.
Blood transfusion/plasma exchange: Ensure the precise establishment of high-flow pathways.
5. Areas with insufficient medical resources
Primary clinics: Making up for the lack of experience among medical staff.
Battlefield/Disaster rescue: Rapid operation under poor lighting and rudimentary equipment conditions.
6. Users outside the medical field
Veterinarian: Intravenous infusion for pets (such as the ear vein of cats and dogs).
Tattoo artist/beautician: Avoid injecting fillers into blood vessels or getting tattoos.
Medical student teaching: Vascular anatomy visualization teaching AIDS.
