Baffle plate can be blocked and be tightly connected mouth, and the liquid ensured from connector outflow flows into human body out of needle tubing completely；The ring simultaneously
Shape baffle plate also acts as position-limiting action, effectively prevents the oversize distance of needle tubing retraction, causes acupuncture treatment depth inadequate.
Preferably, desiccants are filled with the annular space that the seal membrane and needle stand bottom are surrounded；
In order to ensure the drying of seal membrane, and then extend the service life of the present invention.
Preferably, discoloration powder is mixed with the desiccants；Such as anhydrous cupric sulfate, color shifting ink；When
After syringe needle uses once, liquid is by the seal membrane contact discoloration powder of breakage, and now needle stand discoloration, the structure can facilitate
Differentiation which syringe needle be previously used, be also convenient for patient and assist supervision, prevent doctor from making mistakes in chaos, using mistake.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of this automatic damage safety syringe needle one embodiment.
Embodiment
Embodiment
In the embodiment shown in fig. 1, this automatic damage safety syringe needle includes the needle tubing 1 and needle stand 2 of hard；
Connector 3 extend internally, for connecting syringe is offered in the bottom center of the needle stand 2；At the end of the bottom 21
The passage 211 of the circumferentially equidistant arrangement along the connector 3 is further opened with face；Consolidate in the upper end periphery of the connector 3
Surely there is seal membrane 4 parallel with the bottom 21, in a ring；Surrounded in the seal membrane 4 and the bottom 21 of needle stand 2
Desiccants 5 are filled with annular space；Discoloration powder is mixed with the desiccants 5；It is sliding in the needle stand 2
It is dynamic that the piston sheet 6 parallel with the seal membrane 4 is installed；The needle tubing 1 is vertical to be fixed on the piston sheet 6；It is described
