Qualmedi QV-500 vein finder with wheeled stand, handheld near-infrared vein projection device with mobile stand, Ref: QV-500
Qualmedi QV-500 vein finder with wheeled stand
The QV-500 handheld vein finder illuminates the skin with near-infrared light: haemoglobin absorbs the infrared light, the device detects this and projects the image of the superficial veins in real time directly onto the skin above the veins. The puncture site can therefore be identified with the naked eye, without a separate screen.
Mounted on the wheeled mobile stand, the device can be fixed at the required height so that the healthcare professional can use both hands during venipuncture or cannulation. The device can also be used handheld.
Main features
- Projection vein imaging: the vein image appears exactly on the skin above the vein.
- Two modes: optimisation mode for a clearer, continuous vein image, sport mode for fast scanning.
- 10 projection colours for different skin tones and lighting conditions.
- 7 brightness levels and inverse mode (veins shown light or dark).
- 5 image sizes: for adults, children and infants.
- Replaceable lithium battery: at least 2.5 hours of continuous use, automatic sleep mode after 10 minutes of inactivity.
- Wheeled mobile stand: stainless steel, height adjustable, 5 lockable castors.
Areas of use
- Blood sampling, venipuncture, peripheral cannula insertion, IV access
- Patients with difficult venous access: children, elderly, obese or dehydrated patients, patients with darker skin
- Hospital wards, emergency care, practices, laboratories, blood collection points, aesthetic and dental practices
