摘要： An access device includes an access assembly for percutaneously accessing an anatomical space in a patient. An aspiration assembly is operable to generate negative pressure in a fluidic channel of the device. The fluidic channel places the access assembly in fluid connection with the aspiration assembly. A fluid tube has a first tube end connected to the access assembly, a second tube end connected to the aspiration assembly, and a tube body. The tube body defines a manometer tube portion spaced apart from both the first and second tube ends. The manometer tube portion acts as at least part of a manometer when the device is in a manometer mode. The manometer tube portion has adjacent first and second manometer tube ends and an inflection point substantially reversing the direction of the manometer tube portion at a location spaced apart from both the first and second manometer tube ends.
