Specific embodiment
The embodiments of the present invention are described further with reference to the accompanying drawing:
As shown in Figures 1 to 5, micro-shaping filler syringe described in the utility model, including syringe needle 1, injection-tube 7,
Piston 6 and piston rod 8, are equipped with connector 2 between syringe needle 1 and injection-tube 7, axially inside running through for connector 2 has injection logical
Road 11, the front end of connector 2 are equipped with the detection mouth 13 being connected to injection canal 11, and detection mouth 13 is equipped with detection valve 12, detection
Mouthfuls 13 end is connected with detection pipe 3, and detection pipe 3 is connected with negative pressure device by gas-guide tube 4, the rear end of connector 2 be equipped with
The corresponding introduction valve 14 of injection canal 11；The bottom of piston 6 is fixed with link block 20, is sequentially reduced in link block 20 equipped with internal diameter
The first rank hole 22, second-order hole 16 and third rank hole 21, the protrusion part of piston 6 is fixed in the first rank hole 22, second-order
Be equipped with limited block 17 in hole 16, be fixed with guide rod 18 on limited block 17, guide rod 18 pass through third rank hole 21 and with piston rod 8
It is fixedly connected, spring 19 is cased on guide rod 18, spring 19 is between link block 20 and piston rod 18.
In preferred embodiment: negative pressure device is inflated rubber air bag 5, and gas-guide tube 4 connects the air inlet of inflated rubber air bag 5
Mouthful；The front end of connector 2 is equipped with the first connector 10 to match with the first connecting hole 9 of syringe needle 1, and the rear end of connector 2 is set
There is the second connecting hole 15 to match with the end of injection-tube 7.
In use, pulling piston rod 8, guide rod 18 drives limited block 17 to move backward, is close to third rank in limited block 17
When the edge in hole 21, limited block 17 can drive link block 20 to move backward, to move backward with piston 6, by filler
In inspiration injection-tube 7, then the second connecting hole 15 of connector 2 is mounted on the end of injection-tube 7, by the first of syringe needle 1
Connecting hole 9 is mounted on the first connector 10 of connector 2, is detected valve 12 at this time and is in off state with introduction valve 14, then
By squeezing inflated rubber air bag 5, make to generate slight negative pressure in detection pipe 3, then syringe needle 1 is inserted into patient's beauty by healthcare givers
Position, open detection valve 12 can determine that syringe needle 1 is not inserted into blood vessel, then can close inspection if entering detection pipe 3 without blood
Side valve 12 opens introduction valve 14, and then, healthcare givers pushes piston rod 8, and guide rod 18 pushes limited block 17 in second-order hole 16
Interior sliding, therefore piston 6 will not move, 8 compressed spring 19 of piston rod at this time, after spring 19 is compressed to a certain degree, spring
19 elastic force is greater than the frictional force between piston 6 and injection-tube 7, and spring 19 can push link block 20, so that piston 6 be pushed to transport
It is dynamic, by filler injection such as patient's beauty position.
Micro-shaping filler syringe described in the utility model can determine that syringe needle 1 without pumpback filler syringe
Whether blood vessel is inserted into, it is therefore prevented that the blood of extraction pollutes filler；Also, after 8 persistent movement a distance of piston rod, piston
6 just understand movement injection filler, and control driving velocity convenient for healthcare givers has to control the initial injection speed of filler
Effect improves the working efficiency of healthcare givers.
