Who is Vein Finder suitable for?
Aug 08 , 2025
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 va...

How does Optical Coherence Tomography reduce motion artifacts?
Aug 08 , 2025
1.Improvements at the hardware level (1) Increase the scanning speed Frequency domain OCT (FD-OCT) : Compared with time domain OCT (TD-OCT), FD-OCT has A faster scanning speed (up to tens of thousands to hundreds of thousands of A-scans per second), significantly reducing artifacts caused by patients' minor movements (such as eye tremors and breathing). Swept-frequency OCT (SS-OCT) : By rapidly tu...

How does the Table Stand Enhanced Vein Finder work?
Jul 24 , 2025
I. Core Technical Principles Near-infrared imaging (NIR Technology) The absorption characteristics of hemoglobin: Deoxyhemoglobin in veins has a higher absorption rate for near-infrared light of specific wavelengths (typically 700-900nm) than that in surrounding tissues. Reflection difference imaging: The device emits near-infrared light onto the skin, and the camera captures the reflection signal...

What roles does the vein finder device play in emergency scenarios?
Jul 17 , 2025
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 ...

Sudden blurring of vision could be a red alert for a systemic illness
Jul 10 , 2025
Exudative Retinal Detachment (ERD) is a lesion in which the neuroepithelial layer of the retina separates from the pigment epithelial layer without holes. The core mechanism is the destruction of the blood-retinal barrier or the imbalance of choroidal osmotic pressure, resulting in abnormal accumulation of plasma, lipids or blood in the subretinal space. Unlike rhegmatogenous or tractional detachm...
