Preferably, there is the check valve 20 for being placed in 6 left side of second inner chamber on the syringe 1, extraneous air is through check valve
20 enter second inner chamber 6.
Preferably, the right end of the syringe 1 is equipped with the first through hole 21 for making first inner chamber 5 be connected to 1 outside of syringe
With the second through-hole 22 for making second inner chamber 6 be connected to 1 outside of syringe.
Preferably, the right end of the syringe 1 has outer rim boss 23, when carrying out liquid extraction or injection, outer rim is convex
Platform 23 can provide effective stress support.
The present invention is in use, progress liquid extraction operation is pulled outwardly dynamic pressure with outer rim boss 23 for stress supporting point first
Handle 14 makes the first push rod 4 and the second push rod 12 that first piston 3 and turbofan 13 be driven to slide respectively, and the first of 3 left side of first piston
Negative pressure is generated in inner cavity 5, liquid is inhaled into first inner chamber 5, negative pressure, extraneous air are generated in the second inner chamber 6 in 13 left side of turbofan
Second inner chamber 6 can be entered through check valve 20；Meanwhile generating high pressure in the first inner chamber 5 on 3 right side of first piston makes air through first
Through-hole 21 is discharged, and generating high pressure in the second inner chamber 6 on 13 right side of turbofan makes portion of air be discharged through the second through-hole 22, another portion
Duct of the air through turbofan 13 is divided to enter in the second inner chamber 6 in 13 left side of turbofan, above-mentioned air circulation process makes liquid extract
The drag effects that process will not be changed by first inner chamber 5 and 6 air pressure inside of second inner chamber.
When carrying out drug injection, syringe 1 is clamped using index finger and middle finger, with outer rim boss 23 for stress supporting point, is pushed away
Dynamic pressure handle 14 makes the first push rod 4 drive the sliding in first inner chamber 5 of first piston 3, meanwhile, the second push rod 12 drives turbofan 13 to exist
Sliding in second inner chamber 6, drug are pressed into the case where the pressure that external thrust generates acts in syringe needle 2 through first piston 3, and through needle
First 2 enter human body, at this point, due to the one-way flow characteristic of check valve 20, the gas in the second inner chamber 6 in 13 left side of turbofan is by whirlpool
Fan 13 is compressed and can not be discharged through check valve 20, thus the partial shrinkage gas is forced into the duct of turbofan 13, and due to pressure
The gas pressure of contracting gas, when flowing through the duct of turbofan 13, the flabellum of turbofan 13 is generated compressed gas by gas pressure
Movement, to make turbofan 13 generate rotation, when turbofan 13 rotates, through transmission shaft 18, second gear 16, third gear 19, first
The gearing of gear 15 and sleeve 17, cam 11 generate rotation.
Due to the elastic force of spring 9, sliding block 10 contacts with the extruding of cam 11 and generates frictional force, therefore cam to be made 11 rotates
Sliding block 10 need to be overcome to squeeze generated frictional force；When injection speed is smaller, pressure of the turbofan 13 to the air in second inner chamber 6
Contracting speed, that is, gas compression amount in the unit interval is smaller, and the air pressure that the flabellum of turbofan 13 is subject to is smaller to be not enough to overcome cam 11
With the frictional force between sliding block 10, therefore turbofan 13 does not generate rotation.
When the thrust being applied on pressure handle 14 increases injection speed increase, turbofan 13 is to the air in second inner chamber 6
Compression speed increases, and the air pressure that the flabellum of turbofan 13 is subject to increases and gradually overcomes the friction between cam 11 and sliding block 10 therewith
Power, to make turbofan 13 generate rotation with moving cam 11；The rotation of cam 11 makes to produce between sliding block 10 and the lug boss of cam 11
The lug boss of raw Frictional Slipping, cam 11 pushes sliding block 10 to the direction sliding far from 7 axis of disk and is squeezed to the generation of sliding block 10
Pressure, the sliding of sliding block 10 make sliding block 10 contact and generate frictional force with the extruding of the inner wall of first inner chamber 5, so make disk 7 and
The movement speed of first push rod 4 reduces, and injection speed reduces or the speedup of injection speed reduces.
Injection speed is faster, and the gas compression speed in second inner chamber 6 is faster, and air pressure is also corresponding bigger, and turbofan 13 generates
Rotation torsion also accordingly increase, thus the lug boss of cam 11 increases the extruding force of sliding block 10, sliding block 10 and first inner chamber 5
Between extruding force increase the frictional force between sliding block 10 and first inner chamber 5 is made to further increase therewith, injection speed reduce or
Speedup process slows down and gradually tends towards stability.
Meanwhile when carrying out injecting liquid drug, due to being connected to for first through hole 21 and the second through-hole 22,3 right side of first piston
First inner chamber 5 and the second inner chamber 6 on the right side of turbofan 13 keep circulating with outside air always, therefore will not in the part cavity
Negative pressure is generated because of the sliding of first piston 3 and turbofan 13, the smooth-going of injecting liquid drug process will not be by unnecessary resistance.
When the thrust reduction being applied on pressure handle 14 makes injection speed slow down, due in sliding block 10 and first inner chamber 5
Frictional force between wall reduces or disappears, therefore resistance when injection reduces or disappears, even if thrust reduces at this time, due to no longer
Need to overcome larger resistance, therefore still can get stable injection effect, injection speed will not generate suddenly substantially reduce or
Stop.
Structure of the invention is ingenious, easy to use, according to the variation of injection speed, in the unit interval on the left of turbofan second in
The gas compression amount of intracavitary constantly changes and generates different gas pressures, and the rotating speed and torsion of turbofan also generate corresponding variation
So that the extruding force that cam is applied to sliding block is generated variation, and then change the frictional force between sliding block and syringe inner wall, realizes injection
Effective limitation of speed；Simultaneously as the thrust being applied on pressure handle is bigger, the frictional force between sliding block and syringe inner wall is bigger
So that injection speed reduction or speedup is reduced, therefore how the thrust no matter being applied on pressure handle increases, has always corresponding increased
Frictional resistance reduces the speedup of injection speed, and injection speed is made not will produce sudden wide variation, not only can be effective
Mitigate pain and discomfort that the drastically wide variation of injection speed is brought to patient, also can make medical staff that need not carefully control
Propulsive liquid dynamics processed, even if its propulsive liquid speed will not make injection speed generate significant change when changing in the range of setting.
Further, since the compressed gas in injection process in second inner chamber can only be discharged through the duct of turbofan, therefore pass through
Setting to duct size can obtain different velocity limiting effects, to meet different requirements.
