Shooting cylinder 1 is connected, and liquid plate 61 is provided with out in the opening of the other end, go out on liquid plate 61 uniform intervals in a ring be provided with it is multiple go out liquid
Hole 62.Thin bar 40 is for coordinating the bullet in insertion needle 6.Taper running-on 70 is offered inside needle guard 7, for engagement sleeves
If being connected on syringe needle 6, it is provided with the inwall of needle guard 7 for coordinating the fixture block 71 being plugged in T-slot 60.T-slot 60 and card
The quantity of block 71 is identical, can be one or more.
The thin bar 40 of bullet is set,, can be by the fully-inserted tapered needle 6 of thin bar 40 when piston 4 is pushed into bottom to day
Medicament agent in tapered needle 6 goes out, and so as to reduce pharmaceutical quantities remaining in syringe needle 6, reduces the waste of medicament.
The exit of the front end of needle guard 7, which is provided with draining plate 72, draining plate 72 uniform intervals in a ring, to be had for going out liquid
It is additionally provided between multiple delivery holes 73 that hole 62 coordinates, the gap of multiple delivery holes 73 on multiple gas ports 74, gas port 74
It is provided with waterproof ventilated membrane 75.It is size identical circular slab to go out liquid plate 61 and draining plate 72, fluid hole 62, delivery hole 73 and is led
Stomata 74 is the circular port of size all same, and its quantity is identical；The center of circle of fluid hole 62 is to going out between the center of circle of liquid plate 61
The center of circle to the distance between the center of circle of draining plate 72 and the center of circle to the center of circle of draining plate 72 of gas port 74 of distance, delivery hole 73
The distance between all same, so as to realize that delivery hole 73 is turned on fluid hole 62 or led with gas port 74 by rotating draining plate 72
Logical switching.
Taper running-on 70 is offered inside needle guard 7, is set on tapered syringe needle 6, can be arranged tighter, it is ensured that sealing effect
Really.After needle guard 7 is set on syringe needle 6, the fixture block 71 on the inwall of needle guard 7, which coordinates, to be plugged in the transverse groove of T-slot 60, rotary needle
After set 7, fixture block 71 is slid into the cannelure of T-slot 60, so that needle guard 7 is fixed on syringe needle 6, when removing, is reversely rotated
Needle guard 7, fixture block 71 is skidded off by transverse groove to take out needle guard 7；It is achieved thereby that needle guard 7 and syringe needle 6 are detachably connected,
And sealing between the two can be ensured well, prevent liquid from oozing out.On the other hand, after needle guard 7 is located on syringe needle 6, syringe needle 6
Needle guard 7 is rotated to bottom, fixture block 71 is slid into T-shaped by the draining plate 72 for going out liquid plate 61 and the front end of needle guard 7 of front end just to being close to
During one end of the cannelure of groove 60, the delivery hole 73 on draining plate 72 is just with fluid hole 62 just to turning on, the medicine in injection tube 1
Agent can the fluid hole 62 through the front end of syringe needle 6 flow into the delivery hole 73 of needle guard 7 front end, then flow to puncture needle 8, you can carry out normal defeated
Liquid；Needle guard 7 is revolved into reverse rotation on earth, when the fixture block 71 is slid into the other end of the cannelure of T-slot 60, on draining plate 72
Gas port 74 is just with fluid hole 62 just to turning on, and the medicament in injection tube 1 can not flow to puncture needle 8, but by promoting forward
Pushing handle 3, through fluid hole 62 can flow into gas port 74, then discharged by puncture needle 8 by gas unnecessary in injection tube 1；Medicament without
Method is through the waterproof ventilated membrane 75 on gas port 74, therefore medicament will not be discharged.So as to which the gas in injection tube 1 can be discharged,
And medicament will not be discharged again while gas is discharged, the waste of medicament can be prevented effectively from.
The mark of exhaust or transfusion is respectively arranged with the upper and lower ends of the cannelure of T-slot 60, to facilitate medical personnel
Use.
In one embodiment, the quantity of fluid hole 62, delivery hole 73 and gas port 74 is 6, it is uniform in a ring between
Central angle between setting, two adjacent fluid holes 62 is that the central angle between 60 °, two adjacent delivery holes 73 is
60 °, the central angle between two adjacent gas ports 74 is 60 °, and gas port 74 is arranged in the middle of the gap of delivery hole 73, i.e. phase
Central angle between adjacent delivery hole 73 and gas port 74 is 30 °.When rotation draining plate 72 makes fixture block 71 by the longitudinal direction of T-slot 60
When one end of groove slides to the other end, draining plate 72 just rotates 30 °, i.e., just complete by delivery hole 73 and fluid hole 62 just to,
The switching of gas port 74 and fluid hole 62 just between.
