Title
(EN) PUNCTURING DEVICES, PUNCTURING SYSTEMS INCLUDING THE PUNCTURING DEVICES, AND METHODS THEREOF
(ZH) 穿刺装置、包括该穿刺装置的穿刺系统及其方法
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.
(ZH) 本文公开了穿刺装置和包括穿刺装置的穿刺系统。此类穿刺装置和穿刺系统包括根据血氧、阻抗或血压来感测静脉血与静脉血之间的差异。因此,穿刺装置和穿刺系统能够区分静脉穿刺与动脉穿刺。还公开了用于区分静脉穿刺与动脉穿刺的穿刺装置和穿刺系统的方法。
