Catheter assembly

Provided herein is a catheter assembly comprising: a catheter adapter having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end along a first longitudinal axis; a catheter extending from the distal end of the catheter adapter; a dressing comprising a proximal end, a distal end, and a first side and a second side extending between the proximal end and the distal end, the dressing defining a second longitudinal axis and being configured to cover at least a portion of the catheter adapter at a site penetrating into a patient's vasculature, the dressing further includes an upper surface and a lower surface, the lower surface configured to contact a patient's skin; and a tourniquet configured to apply a radially inward pressure to a limb of a patient near the penetration site, the tourniquet configured to couple with the dressing. 在本文中提供一种导管组件，所述导管组件包含：导管适配器，所述导管适配器具有近侧端、远侧端、以及沿着第一纵向轴线在所述近侧端与所述远侧端之间延伸的管腔；导管，所述导管从所述导管适配器的所述远侧端延伸；敷料，所述敷料包括近侧端、远侧端、以及在所述近侧端与所述远侧端之间延伸的第一侧和第二
