Part, sealing ring and seal, it is rectangular hollow structure that the seat body uses cross section, described seat body one end and institute
State spike body to be wholely set, the seat body other end outside is provided with the shackle member, is set on the outside of the shackle member
Sealing ring is equipped with, the sealing ring uses rubber seal, the seal is provided with the outside of the sealing ring, it is described
Seal includes pressure bladder, support member, clamping hypotenuse portion and air bag passage, and the clamping hypotenuse portion uses cross section
It is the structure of " L " type, the clamping hypotenuse portion is arranged on the sealing ring, is set in the clamping hypotenuse portion inside upper part
The pressure bladder is equipped with, the pressure bladder bottom is provided with the air bag passage, set inside the pressure bladder
Support member is equipped with, the support member uses " V " type structure, the needle holder containment vessel is provided with the outside of the needle holder.
The inserting needle limiter is arranged at the spike body other end 5-8mm.
Finger supporting part is provided with the outside of the needle holder containment vessel, is provided with inside and outside the finger supporting part anti-
Sliding line.
Beneficial effects of the present invention are：Compared with prior art, by the inserting needle limiter being arranged in spike body, side
Just medical worker can control depth of needle when being injected to inoculation personnel, it is to avoid easily injure inoculation people because inserting needle is too deep
The nerve of member, and the excessively simple and easy liquid reflux that makes of inserting needle, it is to avoid the waste of medicine, rubber is coated with the outside of inserting needle limiter
Layer, it is to avoid inserting needle limiter causes to damage to the skin of patient；The setting of needle holder containment vessel, by needle holder containment vessel
Connecting portion can not only be protected, prevent connecting portion from damaging or contaminated；The design of shackle member be then for
Enable that syringe needle is flexibly connected with needle handle, and method is simple in connection；Be provided with the outside of shackle member sealing ring and
Seal, by sealing ring and the sealing function of seal, is prevented from Drug leakage at connecting portion.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure：1 is spike body, and 2 is inserting needle limiter, and 3 is needle holder containment vessel, and 4 is finger supporting part, and 5 is seat
Body, 6 is shackle member, and 7 is sealing ring, and 8 is pressure bladder, and 9 is clamping hypotenuse portion, and 10 is air bag passage.
Specific embodiment
Technical scheme is further described below by specific embodiment.
As shown in figure 1, wherein, 1 is spike body, and 2 is inserting needle limiter, and 3 is needle holder containment vessel, and 4 is finger
Supporting part, 5 is seat body, and 6 is shackle member, and 7 is sealing ring, and 8 is pressure bladder, and 9 is clamping hypotenuse portion, and 10 are
Air bag passage.
