1. A nasogastric tube, comprising:
a first tube; a second tube, having two ends and an assembling part formed on one end of the second tube; a connector disposed between the first tube and the second tube to define a flow channel therebetween, a first connection end of the connector being connected to the first tube, a second connection end of the connector being connected to the second tube, a positioning sleeve formed on the second connection end and extending to form a connection part from the flow channel that connects and fluidly communicates with the assembling part of the second tube, the positioning sleeve and the connection part being laterally offset one from the other by a gap formed therebetween; wherein a displaceable locking unit disposed on the assembling part is displaced to engage or disengage a flange portion of the connection part, the displaceable locking unit having opposing first and second ends for releasable engagement with the connection part, the positioning sleeve being disposed to encompass an upper portion of the displaceable locking unit, the connection part having the flange portion at a lower section of the connection part, said first end of said displaceable locking unit being pivotably displaceable within the gap upon compressive force applied to the second end of the locking unit for release of the first end from interference with the flange portion, the connector is adapted for placement in a human nasal cavity and adapted for placement into a nostril using the positioning sleeve, and a part of the positioning sleeve is adapted to protrude out of the nostril. |
