Innovation and Care


Vein Visualizer that uses infrared light to detect the patient's vascular map in high definition and reduces the number of punctures on patients.
Comfort and safety during treatment

Veinviewer is a state-of-the-art venous visualization technology offered by the Oncoclínicas Group.

The VeinViewer is a device that uses infrared light to detect the subcutaneous vascular map and create a high-definition digital image of the patient’s veins, projected directly onto the surface of the skin.

Studies evaluating this technology have found that it can locate veins up to 15mm deep.

VeinViewer Applications

The vein viewer is used as a way to provide a better experience for the patient. By directing the caregiver to the vein, it reduces the number of punctures, potentially improves IV catheter dwell time, and prevents associated complications.

How VeinViewer is used in oncology

A peripheral intravenous catheter (or cannula) is a device that is used to deliver solutions and medications directly into veins, such as during chemotherapy. It is also indicated to maintain hydration in patients who are unable to do so orally (that is, who cannot ingest liquids at the moment).

Although its placement is relatively simple, it can cause discomfort to some patients, especially when the vein is not punctured on the first attempt. Individuals with cancer may need several cycles of chemotherapy or other intravenous infusions. In this context, it is very important that they feel safe and undergo as few punctures as possible.

The vein viewer is highly recommended in this scenario, especially among younger patients with darker skin pigmentation or those who have veins that move around more, situations that often make puncture difficult.

How VeinViewer works

In pre-access (before the puncture) – when a nurse analyzes the patient’s veins before making a puncture, the most apparent one is not always the best option for placing the access. VeinViewer does this previous evaluation and offers the professional the best alternatives. It’s able to locate veins that are clinically relevant for a peripheral procedure, up to 10mm deep for the placement of a peripheral intravenous catheter, or up to 15mm deep for blood sampling.

During puncture – some unpredictable factors can make catheter insertion challenging, making it necessary to restart the procedure from scratch. The images projected by the VeinViewer allow the professional to change strategy immediately and finish the catheter insertion without the need to puncture the vein again.

After access – once the procedure is finished, the vein viewer confirms that the procedure was successful by demonstrating the IV fluid flow and pointing out whether the catheter is working properly. It is also able to detect the presence of a hematoma as it forms, and thereby prevent an infiltration (injury and perforation of the vein, resulting in the drugs infiltrating the tissues near the venous catheter insertion).
