Vystar Female/Male ramp of two 3-way stopcocks is an add-on device for intravenous catheters comprising:

• a body molded in a lipid-resistant raw material (polycarbonate) and transparent to detect air bubbles to facilitate the priming of the device.
•  stopcocks in polyoxymethylene (POM), each stopcock having a different color.

The extension tube supplied with Vystar ramps is made of 3 layers.

The outer layer is in PVC, the inner layer is in Polyethylene without additives, material presenting a high chemical inertness and the intermediate layer is Ethyl Vinyl Acetate, material linking the inner and the outer layers.
This structure allows to minimize interations with drugs and leaching of plasticizers from the PVC into the administered solutions.
