Dynamic primary push rod, is together injected medicine.
2nd, when two kinds of arcotics are injected, pull secondary pushing block, secondary push rod that the first arcotic is sucked into secondary injecting cavity, afterwards
Block is promoted mainly in pulling, and second arcotic is sucked main injecting cavity by primary push rod, therefore respectively can be sucked two kinds of different arcotics not
In same injecting cavity, can first promote promote mainly block afterwards, promote secondary pushing block to be injected respectively afterwards, it is also possible to promote secondary pushing block,
Two kinds of arcotics are together injected.
Therefore this anestetic needle has various occupation modes, and simple structure can be adjusted flexibly, and injection direction and puncture direction
It is identical, it is avoided that increase patient's pain.
In a kind of above-mentioned drug injection modified anestetic needle, main syringe front end has a master shield, main syringe needle with
Master shield connects, and secondary syringe front end has secondary baffle plate, and secondary syringe needle is connected with secondary baffle plate, and secondary syringe needle penetrates secondary baffle plate, and makes secondary pin
Hole connects with secondary injecting cavity, and secondary baffle plate bottom surface is fitted with master shield top surface, and secondary baffle plate is enclosed in main pin hole one end, secondary baffle plate bottom
Face is provided with some fluting shape flow path grooves, and flow path groove two ends connect respectively with main injecting cavity and main pin hole.
Therefore structure is relatively simple stable.
In a kind of above-mentioned drug injection modified anestetic needle, described main syringe needle and secondary syringe needle is coaxially disposed,
And secondary needle tip passes main syringe needle.
Therefore effectively two kinds of arcotics can be separated.
In a kind of above-mentioned drug injection modified anestetic needle, described main syringe and secondary syringe is transparent material
Material is made.
Compared with prior art, the invention has the advantages that：
This anestetic needle has various occupation modes, can be adjusted flexibly, and injection direction is identical with direction is punctured, and is avoided that increasing
Plus patient's pain.
