Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 5, including controlling axial and opening syringe body 1 towards the right side, coaxial sliding connection has ejector pad 2 in syringe body 1, the coaxial push rod 3 that is fixed with of 2 left ends of ejector pad, a plurality of draw-in grooves 4 that open up and left right direction equipartition have been seted up on the push rod 3, 1 left end of syringe body is equipped with fore-and-aft direction's rhombus ring 5, 5 internal rotations of rhombus ring are connected with fore-and-aft axial guide bar 6, be fixed with the limiting plate 7 that can insert its corresponding side draw-in groove 4 on the guide bar 6, 1 upside of syringe body is equipped with a plurality of pressure lines 8 along left and right direction equipartition, 1 right-hand member threaded connection of syringe body has the three-way valve 9 of shape of falling T, threaded groove 10 has been seted up in the free end of three-way valve 9.
In order to enable the limiting plate 7 to swing, the rhombic ring 5 is provided with an abdicating groove 12 with an upward opening, and the limiting plate 7 is positioned in the abdicating groove 12 and can swing in the abdicating groove 12.
In order to facilitate the separation of the limiting plate 7 from the clamping groove 4 and the automatic resetting of the limiting plate 7, the upper side of the limiting plate 7 is connected with the side wall of the abdicating groove 12 through the spring piece 13, and the left end of the guide rod 6 penetrates through the diamond-shaped ring 5 and is coaxially provided with the knob 14.
In order to facilitate the confirmation of the connection direction of the three-way valve 9, the lower side of the three-way valve 9 is provided with a directional arrow 15 which is in the left-right direction and faces the syringe body 1.
In order to protect the unused channel, the upper end of the three-way valve 9 is coaxially and threadedly connected with a rubber plug 16.
In order to facilitate the examination of the suction amount of the pus, a plurality of scale marks 17 uniformly distributed along the left and right directions are arranged on the lower side of the injector body 1.
