摘要：
Disclosed are devices, systems, and methods for providing access to a patient. The patient access device comprises a proximal end, a distal end and a lumen therethrough. The patient access device further comprises a hollow shaft, an input port and a liquid supply port. At least a portion of the lumen passes through the shaft. The input port is coupled to the lumen, and the lumen and the input port are constructed and arranged to receive an elongate probe. The liquid supply port is in fluid communication with the lumen. The patient access is constructed and arranged to reduce gas from exiting the distal end while a portion of the elongate probe is positioned in the patient access device.
