<P>PROBLEM TO BE SOLVED: To provide a medical spray device preventing interference of an attaching/detaching implement with determination of a spray position and having excellent operability. <P>SOLUTION: This medical spray device has a nozzle attached to a spray body with the attaching/detaching implement and sprays medical solution by compressed air. The attaching/detaching implement includes: a pole trap for loosely fitting a locking pole in a cylindrical housing; and an engaging/disengaging cylindrical body that is located outside the cylindrical housing and inwardly pushes out the locking pole by an advancing/retreating operation. The nozzle includes a medical solution tube, an air tube, an outer tube, an engagement tube for engaging end parts of the medical solution tube and the air tube, and a pole receiving recess. When an insertion end of the nozzle is fitted in a fitting hole, the engaging/disengaging cylindrical body pushes out the locking pole to be engaged with the pole receiving recess and, when the push-out of the locking pole by the engaging/disengaging body is canceled, the nozzle is pushed out from the spray body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
