What it is


EasyVein is an electronic device that permits to detect and visualize the superficial venous structure of the body in real-time.

EasyVein is particularly useful when the venous vessels are very hard to be revealed by conventional analysis.

EasyVein allows to the operator to perform the best sampling or infusion procedure since it shows clearly and precisely where the vessels are located.

EasyVein shows some many details that cannot observed by conventional analysis and thus it guaranties easyer and more secure operative sessions on the patient.

How to use it

EasyVein is a sort of “digital loupe” which cam be interposed between the inspected tissue an the operator since it shows an “augmented reality” scene which reports the conventional image in the background as reference and a superposed false color map of venous vessels.

The output image is shown in real-time and there is no need to perform any sort of calibration or other preliminar procedures but only to position the device at the correct distance to obtain the best visualization for the required purposes. Indeed, moving the device toward the inspected tissue is possible to reveal a better detailed image of the area of interest and mowing the device away from the inspected area it is possible to obtain a general overview.

The positioning is very easy because of a effective support that guaranties that the device remains in the correct position when the operator has choosen the optimal visualization distance and this allows the usage of both the hands of the operator during the operation on the patient.

The needle or catheter insertion can be performed while observing the scene “through” the device buti s also possible to perform a conventional observation of the inspected area with a slight change of observation point.

There is no need of calibration or optimization; in addition to the optimal distance setting, the operator has only to choose the best visualization approach (among three possible choiches) for his purposes through a simple pression on a button.


Application contexts

    • Venous detection aid in difficult patients
    • Asssistance for needles for blood sampling or infusions.
    • Asssistance for venous catheters.




Cases where the device is particularly useful

    • Obese patients.
    • Pediatrics and  neonaotology.
    • Patients with deep and small venous vessels.
    • Patiens with a venous structure compromised by frequent medical treatments (chemiotherapy, clotting factors infusion, etc…) or by other venous vessels disorder.
    • Patients with dark skin.


How does it work


The light is absorbed by different biological tissues in different manners. In particular, the deoxygenated hemoglobin (Hb) absorbs the Near InfraRed radiations, i.e. wavelengths right outside the visible band, in a more effective manner with respect to other biological tissues.

Therefore, through the illumination of the region of interest with this radiation (NIR light) and the acquisition of the image capturing the backscattered radiation allows to create an image with luminosity variations where the superficial venous vessel are located. By alborating these images in real-time it is possible to reveal and show the reconstructed venous map allowing the identification of the best insertion point.


EasyVein Strenghts

    • Aid to the needle and catheters insertion with a “not operator dependent” approach  like with ultrasound systems.
    • Very easy usage: in the vast majority of the cases there is no need of specific training, expecially for experienced operators.
    • Very immediate and  intuitive usage with no need of calibrations or preliminary operations.
    • Autofocus optic so as to ensure the use of the device at different distances from the inspected area.
    • Ease of positioning and use thanks to the power supplied supports that can free both the hands of the operator.
    • Similar approach to a loupe: far for the overview, closer for more detailed information.
    • Three different elaboration modalities:
    • No parallax errors : the device can be  positioned in the preferred orientation by the operator with no risk of a skew between the insertion point suggested by the device and the real best insertion point.
    • Very light and very easy to be transported.
      • NIR image visualization (R): Gray Scale image with the Near InfraRed information contribute. The venous vessels are observed as darker structures with respect to the sorrounding tissues.
      • Low Detail visualization (L): The venous map revealed through the elaboration is superposed to the background  reference image witha false color approach. The elaboration of this modality is devoted to visualize only the higher dimension vessels which are more secure to be punched.
      • High Detail visualization (H): Also in this case the venous map is superposed witha false color approach. This modality allows to show also smaller structure that can be punched in very difficult cases by skilled operators.
    • No parallax errors : the device can be  positioned in the preferred orientation by the operator with no risk of a skew between the insertion point suggested by the device and the real best insertion point.
    • Very light and very easy to be transported.
