Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 give, including controlling axial cylinder 1, 1 left end of cylinder is dismantled through the nipple and is connected with syringe needle 2, and 1 left end of cylinder is equipped with the dead lever 4 that is located syringe needle 2 top and left right direction, offers the spout 5 of left right direction in the dead lever 4, offers on the 5 left side wall of spout about the axial just about the guide way 6 that link up, is equipped with in the spout 5 and can controls and the left end can follow the air inlet needle 7 that stretches out in the guide way 6.

In order to enable the air inlet needle 7 to move left and right, a sliding block 10 tightly attached to the inner side wall of the sliding groove 5 is arranged at the right end of the air inlet needle 7, the sliding block 10 is in sliding connection with the sliding groove 5, and the right end of the air inlet needle 7 penetrates through the sliding block 10 and is fixedly connected with the sliding block 10.

In order to facilitate the movement of the sliding block 10, a rectangular groove 11 which is in the left-right direction and is through up and down is formed in the upper side wall of the sliding groove 5, a connecting rod 12 with the lower end fixed with the sliding block 10 is arranged in the rectangular groove 11, and a pushing block 13 is arranged at the upper end of the connecting rod 12, extends out of the rectangular groove 11.

In order to limit the position of the air inlet needle 7, a slot 14 which is positioned at the left of the rectangular groove 11 and is vertically through is arranged on the upper side wall of the sliding groove 5, and an elastic buckle 15 which can be inserted into the slot 14 is arranged at the front end of the sliding block 10.

In order to release the restriction of the air inlet needle 7, an insertion block 16 is slidably connected in the slot 14, and the upper end of the insertion block 16 can extend out of the slot 14 and the lower end thereof can be contacted with the elastic buckle 15.

In order to prevent the liquid medicine from being discharged from the air inlet needle 7, a water-blocking and air-permeable membrane 17 capable of shielding the air inlet needle 7 is arranged at the rear end of the air inlet needle 7.

When the utility model is used, if medical personnel need to suck the medicine into the needle cylinder 1, the pushing block 13 is moved leftwards, the pushing block 13 drives the connecting rod 12 to move leftwards, the connecting rod 12 drives the slider 10 to move leftwards along the chute 5, the slider 10 pushes the air inlet needle 7 to move leftwards, meanwhile, the slider 10 drives the elastic buckle 15 to move leftwards, along with the movement of the slider 10, the left end of the air inlet needle 7 extends out of the guide groove 6, the elastic buckle 15 is contacted with the left side wall of the rectangular groove 11, at the moment, the elastic buckle 15 swings downwards and is contacted with the upper side wall of the chute 5, the pushing block 13 continues to move leftwards, the elastic buckle 15 is inserted into the clamping groove 14 and pushes the inserting block 16 upwards to enable the inserting block 16 to extend out of the clamping groove 14, at the moment, the pushing block 13 stops moving, the position of the slider 10 is limited;

after the preparation stage is finished, the needle head 2 is inserted into the medicine bottle, the air inlet needle 7 is inserted into the medicine bottle, the core bar moves rightwards at the moment, the core bar drives the rubber plug to move rightwards, along with the rightwards movement of the rubber plug, negative pressure is generated on the left side of the rubber plug in the needle cylinder 1, the medicine in the medicine bottle passes through the needle head 2 and the nipple and enters the needle cylinder 1, at the moment, negative pressure is generated in the medicine bottle, air outside the bottle body enters the bottle through the air inlet needle 7, the medicine suction difficulty is reduced, after the medicine suction is finished, the core bar stops moving, the needle head 2 and the air inlet needle 7 are pulled out of the medicine bottle at the moment, and the medicine suction is;

if the medicine needs to be injected into the medicine bottle, the needle head 2 and the air inlet needle 7 are inserted into the medicine bottle, the core bar is pushed leftwards at the moment, the core bar drives the rubber plug to move leftwards, the rubber plug pushes the liquid medicine in the needle head 2 to move leftwards and flow into the medicine bottle through the needle head 2, at the moment, the air in the medicine bottle is discharged out of the bottle through the air inlet needle 7, and meanwhile, the liquid medicine in the medicine bottle cannot be discharged out of the medicine bottle through the air inlet needle 7 due to the existence of the water-blocking and air-permeable film;

this device need withdraw air inlet needle 7 after finishing using, avoids air inlet needle 7 to stab medical personnel, and concrete operation is: the insert 16 is moved downwards, the insert 16 pushes the elastic buckle 15 to move downwards and move out of the clamping groove 14, the push block 13 moves rightwards at the moment, the push block 13 drives the sliding block 10 to move rightwards through the connecting rod 12, the sliding block 10 drives the air inlet needle 7 to move rightwards and insert into the sliding groove 5, when the right end face of the sliding block 10 is in contact with the right side wall of the sliding groove 5, the push block 13 stops moving, the air inlet needle 7 is restored to the initial position at the moment, and the air inlet needle 7 cannot move out of the sliding groove 5 due to self gravity because the sliding block 10 is tightly attached to the inner side wall of the sliding groove 5.

The rubber plug and the core bar of the utility model are the prior art, and the structure of the rubber plug and the core bar is not described in detail here.
