A switchable adapter for a suction tube has a manifold, a switching base rotatably connected to a pivot portion of the manifold, an air-tight component mounted between the pivot portion of the manifold and the switching base, and a cover mounted on an end of the pivot portion. The switching base has two connecting tubes. When the switching base pivots relative to the pivot portion of the manifold, the connecting tubes alternatively communicate with the manifold by rotation of the switching base. Thus, the switchable adapter is switched to allow the suction tube to suck sputa out of a trachea of a patient. |

1. A switchable adapter for a suction tube comprising:
a manifold having
a main tube having an internal channel defined and extending between a front end of the main tube and a rear end of the main tube;at least one branch tube formed on and protruding from the main tube, and communicating with the internal channel of the main tube; anda pivot portion attached to the rear end of the main tube, and having
an outer surface attached to the rear end of the main tube;an upper end;a lower end;a side recess formed in the outer surface of the pivot portion;an inner sidewall defined in the side recess; anda mounting hole formed through the inner sidewall of the pivot portion and communicating with the internal channel of the main tube; an air-tight component made of resilient material and having a main portion tightly fitted in the side recess of the pivot portion, and having a through hole aligning with and communicating with the internal channel of the main tube; a switching base rotatably connected to the pivot portion of the manifold and having
a bottom panel;an arced sidewall formed on and protruding up from the bottom panel, and having an inner arc surface, an outer arc surface, and two side edges disposed apart from each other;a pivot chamber defined above the bottom panel, surrounded by the arced sidewall, and receiving the air-tight component and the pivot portion with the lower end of the pivot portion facing the bottom panel and the main tube protruding between the side edges of the arced sidewall; andtwo connecting tubes including a first connecting tube and a second connecting tube, and the connecting tubes perpendicularly protruding from the outer arc surface of the arced sidewall; and a cover mounted on the upper end of the pivot portion of the manifold; wherein when the switching base pivots relative to the pivot portion of the manifold, the side edges of the arced sidewall alternatively move toward the main tube, and the connecting tubes of the switching base alternatively align with the through hole of the air-tight component to communicate with the internal channel of the main tube of the manifold. |
