    • An apparatus, method and system for cannulation of blood vessels. The apparatus comprises a sensor assembly including two linear transducer arrays oriented perpendicularly to each other to form a “T” shape to provide substantially simultaneous ultrasound images of at least one blood vessel in a portion of a patient's body in two perpendicular planes. The apparatus may also include one or more Doppler transducer elements to transmit and receive one or more Doppler beams at an incident angle beneath one of the transducer arrays and in alignment therewith to determine blood flow direction and velocity within the at least one blood vessel. The sensor assembly may be disposed within an elongated, flexible, protective sheath and secured to a graphically marked cover to facilitate orientation of the sensor assembly on the patient and guidance of a needle towards a desired target vessel during the cannulation procedure. The cover may also include associated structure to cooperate with a reference location element to place, align and secure the sensor assembly to the patient's skin at a desired location.
    • 用于插管血管的装置,方法和系统。 该装置包括传感器组件,其包括彼此垂直取向以形成“T”形状的两个线性换能器阵列,以在两个垂直平面中的患者身体的一部分中提供至少一个血管的基本上同时的超声图像。 所述装置还可以包括一个或多个多普勒换能器元件,以在所述换能器阵列中的一个的入射角度下发射和接收一个或多个多普勒波束并与其对准,以确定所述至少一个血管内的血流方向和速度。 传感器组件可以设置在细长的,柔性的保护性护套内并且固定到图形标记的盖子上,以便于在插管过程期间传感器组件在患者身上的取向并且针朝向期望的目标血管的引导。 盖还可以包括相关联的结构,以与参考位置元件配合,以将传感器组件放置,对准并将其固定到患者的皮肤上的所需位置。

    • An apparatus is provided for cannulation of blood vessels. The apparatus comprises a sensor assembly including two linear transducer arrays oriented perpendicular to each other to form a “T” shape to provide ultrasound images of at least one blood vessel in a portion of a patient's body in two perpendicular planes. The sensor assembly includes a housing having a graphically marked surface to facilitate orientation of the sensor assembly on the patient and guidance of a needle toward a desired target vessel during the cannulation procedure. The housing is configured to engage a frame element having a pair of wings extending laterally therefrom, the wings each bearing a magnet to cooperate with a reference location element secured to a patient's skin and bearing magnetically responsive shims thereon to place, align and secure the sensor assembly to the patient's skin at a desired location.
    • 提供了一种用于插管血管的装置。 该装置包括传感器组件,其包括彼此垂直定向以形成“T”形状的两个线性换能器阵列,以在两个垂直平面中的患者身体的一部分中提供至少一个血管的超声图像。 传感器组件包括具有图形标记的表面的壳体,以便于在插管过程期间传感器组件在患者身上的取向和针朝向期望的目标血管的引导。 壳体被构造成接合具有从其横向延伸的一对翼的框架元件,每个翼各自承载磁体,以与固定到患者皮肤上的参考位置元件配合,并且在其上承载磁性响应的垫片以放置,对准和固定传感器 在所需位置组装到患者的皮肤上。
