It is caught under right state in locking slot and locks needle cover 21.Nature locking pin 23 locks needle cover 21, makes medicine feeding hole 52 closed,
Drug leakage is prevented, causes to waste.Injection putter 6 is promoted when using, needle cover 21 is moved down with drug storage pipe 2, compressed into medicine spring 24,
After the decrement for entering medicine spring 24 reaches critical value, needle cover 21 is separated in the presence of medicine spring 24 is entered with injection needle 5,
Medicine feeding hole 52 is set to be connected with drug storage pipe 2.
Be cased with as the further improvement to above-mentioned technical proposal, outside the piston rod 61 two ends respectively with drug storage pipe 2 and
What piston 62 was connected pushes away medicine spring 64.Compressed drawing arcotic pusher medicine spring 64 by piston 62, one is produced to piston 62
Thrust, is covered after closure 4, and drug storage space 63 forms a confined space.Injection needle 5 is pierced into after patient skin, patient's
Hypodermis is connected by injection needle 5 with drug storage space 63, and confined space is destroyed, in the presence of the thrust of medicine spring 64 is pushed away
Piston 62 compresses drug storage space 63 automatically, by infusion of medicine patient skin, shortens the operating time, mitigates patient suffering.
As the further improvement to above-mentioned technical proposal, the top of injection putter 6 sets cartoon head portrait.Cartoon head portrait
Infant can be attracted to note, it is to avoid infant is cry and screamed, facilitate doctor to operate.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
