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.

When the utility model is used, the three-way valve 9 is firstly screwed on the injector body 1, so that the directional arrow 15 points to the injector body 1, the three-way valve 9 can be conveniently and better connected, and then the pus cavity drainage tube is screwed at the free end of the three-way valve 9, so that the pus cavity drainage tube can be conveniently protected, and the upper end of the three-way valve 9 is in threaded connection with the rubber plug 16, thereby not only protecting the interior of the three-way valve 9, but also being convenient for connecting other drainage devices;

when the negative pressure pus cavity drainage is needed, firstly, the knob 14 is rotated clockwise, the knob 14 drives the limiting plate 7 to swing upwards along the abdicating groove 12 through the guide rod 6, the spring piece 13 is compressed, so that the limiting plate 7 is not clamped in the clamping groove 4, meanwhile, the push rod 3 is pulled leftwards, the push rod 3 drives the push block 2 to slide leftwards along the injector body 1, so that the injector body 1 generates negative pressure, pus is sucked into the injector body 1 through the drainage tube and the three-way valve 9, and meanwhile, when the clamping groove 4 on the push rod 3 moves leftwards to the lower side of the limiting plate 7, under the action of the spring piece 13, the spring piece 13 drives the limiting plate 7 to swing downwards along the abdicating groove 12, so that the limiting plate 7 is inserted into the clamping groove 4, the injector body 1 can continuously perform negative pressure suction, meanwhile, a negative pressure suction value of 0-10ml is arranged on the pressure line 8, so that the negative pressure suction value is convenient to adjust, stable negative pressure is provided, and the suction efficiency is improved;

after the pus suction finishes, owing to be equipped with scale mark 17 on syringe body 1, can be convenient for observe the volume of pumping out the pus, unscrew syringe body 1 from three-way valve 9 thereupon, no longer carry out the suction of pus, owing to be equipped with check valve 11 in three-way valve 9, can effectually avoid the pus countercurrent, cause cross infection, in time treat the patient simultaneously.
