Enlarged drawing;Fig. 5 is the explosive view of each component in Fig. 1.
In a specific embodiment, fast automatic injection device provided by the present invention, including rear shell 5, front housing 6,
Sleeve 3, bracket 1, push rod 2 and trigger member 4, front housing 6 are connect with rear shell 5, are the shells of fast automatic injection device, in fixation
Portion's part.Sleeve 3 is set in rear shell 5, and it is mobile that rear shell 5 limits 3 axial position of sleeve.Bracket 1 is set in front housing 6, and is supported
It is connected to 3 front end face of sleeve, axial force can be transmitted.It should be noted that referring to before here and below described close to injection
The side of position, after refer to the side far from injection site.Clamped bottle and injection needle are installed in bracket 1, the limitation card of bracket 1
Formula bottle radial motion;Preferably, clamped bottle and injection needle separation, avoid medical fluid from revealing and pollute.Sleeve 3 and the buckle of bracket 1 connect
It connects, fixed clamped bottle;Sleeve 3 and push rod 2 Locating driver spring 7 together, make driving spring 7 before not discharging in compression shape
State.
Push rod 2 is installed in sleeve 3, and clamped bottle can be pushed to move forward.Trigger member 4 is set in front housing 6 and bracket 1
Between, and can move axially, the pressing of trigger member 4 applies certain dynamics in injection site, trigger member 4 move backward setting away from
From driving push rod 2 moves backward.The rear end of push rod 2 has and can have annular groove to the buckle of contract, the rear end of sleeve 3,
The rear end face of rear shell 5 has slot, and the internal diameter of slot is less than the outer diameter of buckle, for shrinking buckle.The fixture block energy of annular groove
It is enough stuck in buckle, after push rod 2 moves backward set distance arrival slot, slot shrinks buckle, the buckle and fixture block of rear end
It is detached from, buckle is shunk.The periphery of push rod 2 is set with driving spring 7, and 7 original state of driving spring is in compressive state, drives bullet
The front end of spring 7 peaks on the intermediate step ring of push rod 2, and rear end peaks on fixture block.When the outer diameter of buckle is less than annular groove internal diameter
When, driving spring 7 discharges, and with the forward movement of driving push rod 2, and then clamped bottle is pushed to move forward, and starts inserting needle administration, completes
Injecting liquid drug.
Fast automatic injection device provided by the present invention is disposable First-aid pen, makes drug containing clamped bottle and disposably
It is fitted into fast automatic injection device with sterile twolip injection needle, using snap-lock, triggering spring technology, with click on fashion
By the lock of driving spring 7 in sleeve 3, release spring power is buckled by triggering, driving push rod 2 moves, complete by several connectors
At inserting needle and injection.Trigger member 4 is pressed into injection site when use and applies certain pressure, inserting needle and note can be automatically performed
Medicine, when there is emergency episode, anaphylactic shock or acute onste etc., ordinary people can complete injection medicine before rescue carrigae comes
Liquid can be reduced the death rate and distress level of patient, one can be operated, easy to operate, easy to use, can be carried around, and pacify
It is complete reliable;Before injection, syringe needle is hidden, and reduces patient's fear;Injection process realizes that fast inserting needle is injected slowly, simple and convenient.
Above-mentioned fast automatic injection device is only a kind of preferred embodiment, is specifically not limited thereto, on this basis can root
It makes having according to actual needs and targetedly adjust, to obtain different embodiments, the rear end of trigger member 4 has hook,
Hook can be set with readjustment spring 8 to contract, the periphery of trigger member 4, and readjustment 8 original state of spring is in compressive state.
The front end of readjustment spring 8 peaks on the intermediate prominent ring of trigger member 4, and rear end peaks on snap ring 12, and snap ring 12 is fixed on front housing 6
Rear end face on, hook position is motionless, can be stuck in hook on snap ring 12, before triggering, snap ring 12 by adjust back spring 8 be fixed on
4 rear end of trigger member, the limit of trigger member 4 readjustment spring 8 and snap ring 12.After pressing trigger member 4, trigger member 4 is moved backward, trigger member
When 4 rear ends hook position pass through rear shell 5, because outer diameter is big, hook is to inside contracting, when removing the power imposed on contact, hook outer diameter
When less than 12 internal diameter of snap ring, readjustment spring 8 discharges, and trigger member 4 is pushed ahead, at this point, injection needle restoring, hidden time.Entire note
The process of penetrating is hidden needle operation, and syringe needle retracts automatically after injection, effectively prevents accidentally stabbing, and reduce user of service and fear
Fear sense and psychological pressure.
On the basis of above-mentioned specific embodiment, those skilled in the art can be according to the difference of specific occasion, to fast
Fast automated injection device carries out several changes, and the rear end face of bracket 1 has step surface, between the hook and step surface of trigger member 4
After having gap, trigger member 4 to trigger, the rear end face of hook can be peaked on step surface, and bracket 1 travels forward by 4 front end of trigger member
Inner surface withstands the movement of 1 front end face of bracket, is easy to transmit driving force, structure is simple, more compact.
Obviously, under the guidance of this thought, those skilled in the art can be according to the difference of specific occasion to above-mentioned
Specific embodiment carries out several changes, further includes protective cap 10, and protective cap 10 is installed at rear shell 5, for encapsulating slot,
The core of protective cap 10 inserts in the limiting slot in buckle, and before being not used, protective cap 10 is buckled on outer housing, and core is inserted in push rod
In 2 slots, guarantee before not removing protective cap 10, the buckle of push rod 2 can not retract, so that the movement of driving spring 7 can not be discharged.It protects
Helmet 10 can prevent maloperation, and when injection need to remove protective cap 10, can press the operation of trigger member 4, safer.
It is important to note that fast automatic injection device provided by the present invention is not intended to be limited to such situation,
It further include cushion 11, cushion 11 is installed at 1 front end of front end and bracket of front housing 6, after driving spring 7 discharges, injection needle,
Clamped bottle etc. plays buffer function when moving forward, and prevents strong collision from causing medicine bottle broken.
Fast automatic injection device provided by the present invention further includes sealing ring in the immovable situation of other components
9, sealing ring 9 is installed between rear shell 5 and front housing 6, for injection needle to be sealed in inside fast automatic injection device, prevents needle
Head pollution, guarantee is sterile, safer, hygienic.
For the fast automatic injection device in above-mentioned each embodiment, rear shell 5 and front housing 6 are connected through a screw thread, and are easy to
Connection, screw thread process is simple, is detachably connected, easy to disassemble, easy to use.Rear shell 5 and front housing 6 can also be connected by buckle
It connecing, structure is simple, and it is disposable, it prevents from dismantling.
In order to further optimize the above technical scheme, clamped bottle is clear vial, is offered on front housing 6 and bracket 1 for looking into
The visual window that whether medical fluid has been injected in clamped bottle seen, is finished by the way that whether visual window observation medical fluid is injected, it is more convenient to use.
In the description of the present invention, it should be noted that the orientation or positional relationship of the forward and backward equal instructions of term is based on attached
Orientation or positional relationship shown in figure, is merely for convenience of description of the present invention and simplification of the description, rather than indication or suggestion is signified
