Description

  The present invention relates to a pipe joint, and more particularly, to a right-angle pipe joint used between an aspirator and a cleaning liquid bottle.

  The prior art will be described with reference to FIG. 1. FIG. 1 is a view showing a sucker of the prior art. As shown in FIG. 1, a sucker 10 according to the prior art is used by being inserted into a trachea of a patient. The other end of the suction device 10 is connected to a negative pressure to extract soot in the trachea. Since the suction device 10 that can be used many times must be periodically cleaned, the cleaning liquid inlet 12 is provided so as to be perpendicular to the side wall of the tubular body 11 of the suction device 10. The cleaning liquid inlet 12 is connected to the cleaning liquid bottle via a pipe.

  The cleaning liquid is sufficiently contained in the cleaning liquid bottle, and the cleaning liquid is sucked into the suction device 10 by the negative pressure, and after the suction device 10 is cleaned, is discharged out of the suction device 10 from the drain pipe 13. By providing an L-shaped tube 40 between the sucker 10 and the cleaning liquid bottle 30 for communication, the cleaning liquid bottle 30 is provided so as to be fixed upright. Therefore, in use, the sucker 10 can be held with one hand and the negative pressure device can be operated with the opposite hand at the same time.

  A disadvantage of the prior art is that the L-shaped tube 40 also moves when the cleaning liquid bottle 30 is shaken. If there is a gap between the L-shaped tube 40 and the cleaning liquid inlet 12, air leaks and the cleaning liquid cannot be sucked well.
