Abstract
(EN)
Disclosed herein are puncturing devices and puncturing systems including the puncturing devices. Such puncturing devices and systems include those that sense a difference between venous blood and arterial blood as a function of blood oxygen, impedance, or pressure. As a result, the puncturing devices and systems are able to differentiate between a venipuncture and an arterial puncture. Methods of the puncturing devices and systems for differentiating between a venipuncture and an arterial puncture for are also disclosed.

L'invention concerne des dispositifs de ponction et des systèmes de ponction comprenant ces dispositifs de ponction. De tels dispositifs et systèmes de ponction comprennent ceux qui détectent une différence entre le sang veineux et le sang artériel en fonction de l'oxygénation, de l'impédance ou de la pression sanguines. Par conséquent, ces dispositifs et systèmes de ponction sont aptes à faire la différence entre une ponction veineuse et une ponction artérielle. L'invention concerne également des procédés de dispositifs et systèmes de ponction permettant de faire la différence entre une ponction veineuse et une ponction artérielle.
