A food reflux reducing two-piece nasogastric tube, comprising:
- a first tube body having a first connector on one end and an insertion portion on another end, a first positioning portion disposed on one end of the first connector away from the first tube body, a protrusion edge being disposed on an outer side of the first connector adjacent to the first positioning portion, the first connector comprising a through hole formed in an axial direction and connected with the first tube body, the through hole comprising an elastic seal portion disposed adjacent to the first positioning portion, the seal portion being provided with a cross break which is normally in a sealing status, a convex portion being disposed on an inner edge of the through hole between the seal portion and the first positioning portion;
- a second tube body having an irrigation portion disposed on one end and a second connector disposed on another end, a second positioning portion being disposed on one end of the second connector away from the second tube body, an insertion combination tube extending from the second positioning portion, the insertion combination tube being connected with the second tube body, two elastic arms extending from an outer side of the second connector toward the insertion combination tube, with a hook portion disposed on a distal end of each of the two elastic arms;
- wherein, when in use, the insertion combination tube is inserted into the through hole of the first connector, such that the insertion combination tube expands the cross break, an outer periphery of the insertion combination tube tightly contacts and abuts against the convex portion, the second positioning portion abuts against the first positioning portion, and the hook portion of the two elastic arms hooks the protrusion edge, such that the second connector is connected with the first connector, and the second tube body is connected with the first tube body;
- and
- a fixing device comprising a fixing member, an adherence member, and a connection member, the fixing member comprising a clamp ring and a first rod body, the clamp ring disposed on one end of the first rod body, the clamp ring detachably clamping the first connector of the first tube body, the connection member comprising a second rod body and a universal ball part, one end of the second rod body being connected with the universal ball part, another end of the second rod body being pivotally and adjustably connected with the adherence member, the adherence member being configured to be adhered on a patient's nose, the connection member being pivotally and adjustably connected with one end of the first rod body of the fixing member through the universal ball part, the first rod body of the fixing member and the second rod body of the connection member being held up with the universal ball part serving as a support, such that the first rod body and the second rod body are configured to be prevented from contacting the patient's nose.
