By providing the small magnetic ball 25 and the small iron ball 26, not only the elastic tube 18 can be swung back and forth by utilizing the magnetic attraction force between the two, but also the medicament discharged from the elastic tube 18 can be sprayed to a larger range, and when the small iron ball 26 attracts the small magnetic ball 25 to be attached to the small magnetic ball, the small magnetic ball 25 and the small iron ball can collide with each other, so that the elastic tube 18 can vibrate at a certain frequency, the sprayed medicament can be in a finer mist shape, and finally the two medicaments can be mixed more fully and uniformly.
Referring to fig. 5, the liquid inlet mechanism comprises a separating cylinder 5, a sealing column 27, a liquid inlet pipe 6 and a liquid inlet needle 7, wherein the liquid inlet pipe 4 is communicated with the inner bottom of the separating cylinder 5, the sealing column 27 is connected in the separating cylinder 5 in a sealing sliding manner, an L-shaped hole 28 is formed in the side wall of the sealing column 27, a groove 29 is formed in the inner wall of the separating cylinder 5, the sealing column 27 is pushed to move by the driving mechanism, the liquid inlet pipe 6 is communicated with the inner top of the separating cylinder 5, and one end, far away from the separating cylinder 5, of the liquid inlet pipe 6 is communicated with the liquid inlet needle 7. As shown in fig. 5, when the injection operation is performed, the driving mechanism makes the sealing post 27 below the groove 29, and at this time, the sealing post 27 can separate the liquid inlet pipe 6 from the liquid inlet pipe 4, and the medicine cannot pass through the liquid inlet pipe 6 or the liquid inlet pipe 4, but can only perform the injection operation through the injection pipe 2;
when the medicine is sucked, referring to fig. 6, the sealing post 27 is pulled by the driving mechanism to move upwards, the L-shaped hole 28 is communicated with the groove 29, and at this time, the medicine can flow into the liquid inlet pipe 4 through the groove 29 and the L-shaped hole 28, and finally flows into the injection cylinder 1 along the elastic pipe 18.
Referring to fig. 1 and 5, the driving mechanism includes a driving rod 8 fixedly connected to the upper end of a sealing post 27, a pulling plate 10 is fixedly connected to the upper end of the driving rod 8, and the pulling plate 10 is connected to the upper end of the separating cylinder 5 through a spring 9. The two pull plates 10 are fixedly connected together through the connecting ring 11, and the connecting ring 11 can enable the two pull plates 10 to synchronously lift. Specifically, by pulling the engagement ring 11, the pulling plate 10 and the driving rod 8 on both sides can move in the vertical direction, and then the sealing post 27 is driven to move.
Referring to fig. 3, a rubber hose 19 is connected to the lower end of the liquid suction pipe 17, a hard pipe 20 is connected to the lower end of the rubber hose 19, a plurality of rotating rings 21 are sleeved on the outer wall of the hard pipe 20, and a plurality of spoilers 23 are fixedly connected to the side walls of the rotating rings 21. Specifically, when the elastic tube 18 swings back and forth, the middle liquid suction tube 17 can be intermittently collided, and the soft rubber hose 19 enables the liquid suction tube 17 on the upper side and the hard tube 20 on the lower side to be in soft connection, so that the hard tube 20 on the lower side without limit can generate transverse vibration, and further the spoiler 23 on the outer side of the hard tube 20 continuously agitates the mixed medicament at the bottom of the injection tube 1, and the medicament is more quickly and fully mixed uniformly. Meanwhile, the rotary ring 21 can also rotate along the circumferential direction of the hard tube 20, so that the rotary ring 21 and the spoiler 23 can rotate in an unoriented manner under the action of inertia, and the stirring and mixing efficiency is further improved.
Referring to fig. 3, a plurality of limiting plates 22 are fixedly connected to the side wall of the rigid pipe 20, and each two adjacent limiting plates 22 are respectively disposed on the upper and lower sides of the swivel ring 21. It should be noted that, by providing the limiting plate 22, the vertical direction of the rotary ring 21 can be limited, so that the rotary ring 21 cannot move up and down, which prevents the rotary ring 21 from falling off the hard tube 20, and also prevents the adjacent rotary rings 21 from being blocked together and not rotating.
When the device is used, when the medicament is sucked, referring to fig. 1, the plug 3 is screwed on the outer side of the injection tube 2, so that the injection tube 2 can be blocked, and air is prevented from being sucked in the process of sucking the medicament. The liquid inlet needles 7 on the liquid inlet pipes 6 on the two sides can be inserted into ampoule bottles or other types of medicine bottles containing medicines, and then the connecting rings 11 are lifted up, so that the pull plates 10 on the two sides can move upwards, the pull plates 10 drive the driving rods 8 to move upwards, and synchronously pull the sealing columns 27 in the separating cylinders 5 to move upwards, so that the L-shaped holes 28 on the sealing columns 27 are communicated with the grooves 29, as shown in fig. 6.
At this time, as in the case of operating a conventional syringe, when the push plate 13 is lifted up, the push plate 13 drives the push rod 12 and the piston 14 to move up, so that negative pressure is generated below the piston 14, and because the syringe 2 below is blocked by the stopper 3, air cannot be sucked from the syringe 2, and therefore, only air can be sucked from the liquid inlet pipes 4 on both sides, so that the medicine in the ampoule or the medicine bottle can be sucked from the liquid inlet needle 7 into the liquid inlet pipe 6, flows into the separating cylinder 5 through the liquid inlet pipe 6, then flows into the L-shaped hole 28 through the groove 29, flows to the lower part of the sealing post 27 through the L-shaped hole 28, finally is sucked into the syringe 1 through the liquid inlet pipe 4 and the elastic pipe 18, and the medicine flowing into the syringe 1 automatically flows into the syringe 2, so that when the piston 14 moves up, the medicine flows to the upper side of the limiting plate 15 along the hard pipe 20, the rubber hose 19 and the liquid suction pipe 17.
It should be noted that when the piston 14 moves up, the sliding rod 16 is driven to move up synchronously, and when the sliding rod 16 moves up, each small iron ball 26 on the side wall of the sliding rod passes through the small magnetic ball 25 in turn, and when a certain small iron ball 26 passes through the small magnetic ball 25, the small magnetic ball 25 can be attracted to move to one side of the small iron ball 26, so that the elastic tube 18 can be driven to swing to one side of the sliding rod 16, and when the small iron ball 26 leaves the small magnetic ball 25, the magnetic attraction between the small iron ball 26 and the small iron ball is weakened, the elastic tube 18 can reset by means of self elastic backswing, so that in the process of moving up the sliding rod 16, the elastic tubes 18 on two sides can swing back and forth, and thus, when medicines are input into the injection tube 1, the swinging elastic tubes 18 can throw the medicines into mist, and the two different mist medicines can be fully and uniformly mixed together, so that after medicines are extracted, shaking operation is not needed, injection operation is effectively saved, and injection operation efficiency is greatly improved;
further, when the elastic tube 18 swings transversely, the elastic tube 18 will collide with the middle liquid suction tube 17 continuously, so that the soft rubber hose 19 can drive the hard tube 20 to vibrate transversely, the rotary ring 21 and the spoiler 23 at the outer side of the hard tube 20 can transversely disturb the mixed medicament flowing into the injection tube 1, so that the mixed medicament can be mixed uniformly and quickly, and in addition, when the hard tube 20 vibrates transversely, the rotary ring 21 can rotate continuously and unidirectionally under the action of inertia, and the spoiler 23 is driven to rotate, so that the mixed medicament can be further promoted to be mixed uniformly and quickly.
When the injection operation is performed, the connection ring 11 is loosened, the spring 9 pulls the pull plate 10 to move downwards for resetting, at the same time, the sealing post 27 in the separating tube 5 also moves downwards for resetting, the L-shaped hole 28 moves to the lower side of the groove 29, as shown in fig. 5, at the same time, the liquid inlet tube 6 is separated from the liquid inlet tube 4 again by the sealing post 27, so that the medicament cannot flow into the injection tube 1 through the liquid inlet mechanism continuously, and simultaneously, the medicament cannot flow back into the separating tube 5 through the elastic tube 18 and the liquid inlet tube 4. Then, the injection needle is arranged outside the injection tube 2, the push plate 13 is pressed to push the piston 14 to move downwards through the push rod 12, so that the mixed medicament sucked into the upper side of the limiting plate 15 can be discharged into the injection tube 2 along the liquid suction tube 17, the rubber hose 19 and the hard tube 20, and finally injected into a patient through the injection needle.
To sum up, the device disperses the medicament discharged from the elastic tube 18 into mist, so that the two medicaments are fully and uniformly mixed, shaking and uniformly mixing operation is not needed, and after the two medicaments are inhaled, the injection operation can be performed by pushing the piston 14 reversely, thus the whole injection process is greatly simplified, a large amount of operation time is saved, and the injection operation efficiency is effectively improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
