Features

Built for clinical precision

VeinRifier uses near-infrared imaging to make subcutaneous veins visible through the skin — reducing failed venipuncture attempts and improving patient comfort.

NIR vein imaging

850 nm infrared LEDs illuminate subcutaneous veins in real time through the camera.

Wireless hardware

BLE-connected ESP32 device pairs instantly with your phone over Bluetooth.

Android app

Capture, annotate, and store patient records securely from any Android phone.

HCCast projection

Mirror the vein overlay onto an external display for team viewing or training.

Patient records

Securely store scan history, demographics, blood type, and clinical notes per patient.

IR intensity control

Adjust LED brightness live from your phone for different skin tones and vein depths.


How it works

From device to display in seconds

VeinRifier combines a custom NIR hardware device with a mobile app to give clinicians a clear view of subcutaneous veins — no invasive procedure required.

1

Power on the device

The ESP32-based VeinRifier hardware starts advertising over Bluetooth automatically when powered on.

2

Connect via the app

Open VeinRifier on your Android phone, go to Settings, tap "Scan & Connect Device" and select VeinRifier from the list.

3

Select the venipuncture site

Choose Antecubital Fossa or Dorsal Venous Arch before scanning to keep records correctly categorised.

4

Capture & view the vein map

Point the phone camera at the site. The NIR LEDs activate and the app overlays the processed vein map within seconds.

5

Save or cast

Save the scan to a patient record, or launch HCCast to project the overlay onto an external screen for the whole team.
