Accordingly, one end portion of the needle 3 is mounted to the needle fixing hole 469 so that the medicine injected through the connecting tube portion 467 can be supplied to the needle 3 through the needle fixing hole 469.
On the other hand, the suction connector 6 communicates with the needle hole 442 of the needle pusher 4, and a plurality of insertion grooves 61 into which the plurality of projection pipes 43 are respectively inserted are formed at the rear.
A plurality of fitting grooves 425 are formed on the outer peripheral surface of the cylindrical body 42 of the needle pusher 4 so as to be recessed in the longitudinal direction. Further, a plurality of insert pieces 65 that are inserted into the plurality of insertion grooves 425 of the cylinder 42 of the needle pusher 4 are formed to protrude from the suction connector 6.
The operation of the embodiment of the present invention will be described below.
The support plate 44 and the holding portion 46 are coupled to the contact plate 468 via the rear opening of the cylindrical body 42, and the support plate 44 and the holding portion 46 are coupled to the inside of the cylindrical body 42 by inserting the needle 3 through the projected tube 43 coupled to the cylindrical body 42.
Thereafter, the needle 3 is inserted into the insertion groove 61 of the suction connector 6 and the projecting tube 43 of the cylindrical body 42 is partially inserted into the insertion groove 61, thereby coupling the needle pusher 4 and the suction connector 6.
Thereafter, the first body 21 and the second body 22 are brought into close contact with the outer peripheral surface of the cylinder 42 and then are relatively grounded to assemble the body 2, and the screw 24 of the body 2 is screwed to the screw 424 of the cylinder 42. After the assembly is completed, the discharge port (not shown) of the injection member is coupled to the connecting tube portion 467 of the grip portion 46.
When the body 2 is held by a hand and the body 2 is rotated in one direction, the grip portion 46 moves forward or backward as the screwed cylindrical body 42 rotates, and the length can be adjusted as the needle 3 moves forward or backward.
Fig. 4(a) shows a state where the needle 3 is exposed to the maximum, and fig. 4(b) shows a state where the needle 3 is inserted. Therefore, as the needle 3 and the grip portion 46 coupled to the cylindrical body 42 move, the length of the needle 3 exposed to the front of the suction connector 6 can be appropriately adjusted.
The present invention is not limited to the above-described embodiments and drawings, and various modifications and applications not illustrated can be implemented, and replacement of constituent elements and modification with other equivalent embodiments can be implemented without departing from the scope of the technical idea of the present invention, and thus modifications and application-related contents of the features of the present invention should be interpreted as falling within the scope of the present invention.
