An instrument for removing by suction saliva, water or other materials generated or used in connection with procedures carried out in the region of the mouth. The instrument includes a substantially tubular, elastic frame arranged for suction, a finger part for attaching the instrument to a finger, and a tip part located, in an axial direction, farther out than the finger part and including a suction inlet. The tip part is arranged to be rotatable around the axial direction of the frame. |

1. An instrument for: (i) sucking saliva or other secretions or objects out of a patient's mouth, nose, throat or lower respiratory tract, and (ii) removing by suction water or other materials generated or used in connection with procedures carried out in the region of the mouth, nose or respiratory tract, the instrument being capable of being disposed on a finger, the instrument comprising:
a substantially tubular, elastic frame part having a channel arranged therein for a suction flow, the frame part including first members and second members, the first members including: one or more receiving grooves, locking protrusions, locking recesses or threads, and the second members including: one or more locking protrusions, receiving grooves, threads or friction fits; a finger part configured to attach the instrument to the finger, said finger part being configured to receive the finger such that the outermost joint of the finger is between both axial ends of the finger part; and a separate tip part located, in an axial direction, farther out than the finger part and including a suction inlet communicating with the channel, the separate tip part being configured to rotate in relation to the frame part in an end to end contact, the tip part including third members and fourth members, the third members including: one or more grooves, recesses, projections or threads, and the fourth members including: one or more grooves, recesses, projections or threads, wherein: the tip part is configured to be rotated around the axial direction of the frame part, the first members and the third members being configured to co-operate with each other for a rotational adjustment of the tip part such that the tip part is rotationally lockable after predetermined lengths of movements, and the tip part is configured to be longitudinally adjusted, the second members and the fourth members being configured to co-operate with each other for the longitudinal adjustment of the tip part such that the tip part is longitudinally lockable after predetermined lengths of movements, the second and fourth members being located at different distances from the tip along the longitudinal axis for adjustment of the tip part in the longitudinal direction. |
