Description
Technical field
The utility model relates to the field of medical instrument technology, specifically a kind of safety injector.
Background technique
Syringe is with being injected into the region that can not be approached for a small amount of liquid or gas or extracting out from which place, mostly
Number situation is to treat to use to patient, its pinhead sleeve of existing syringe is in the front of injection-tube, when there is liquid in injection-tube,
It pushes hard the liquid internal pressure of the piston rod of injection-tube then in injection-tube to increase, at this moment to needle, first forward is pushed away the internal pressure of liquid
Power, when pinhead sleeve loosens on injection-tube, syringe needle will be injected the injection of pipe high internal pressure, and the syringe needle of injection has lethality, such as
Fruit, which is mapped on the person, can injure body, have extremely unsafe factor.
Utility model content
The purpose of this utility model is to provide a kind of safety injectors, are increased with solving the internal pressure inside conventional syringe
Height, when syringe needle loosens, syringe needle will be injected in pipe and inject by pressure, and the syringe needle of injection has lethality, it is easy to hurt people.
To achieve the above object, the utility model provides the following technical solutions: a kind of safety injector, including push rod bottom
Seat, push rod, injection tube body, sealing ring, injecting adaptor, syringe needle and needle cap, the top of the push rod pedestal, which is fixedly connected with, to push away
Bar, the top of the push rod are connected with push rod cup, and the outside of the push rod cup is provided with sealing ring, and the external setting of sealing ring
There is injection tube body, the lower part of the injection tube body is fixedly installed the low side of injection-tube, the top fixed setting of the injection tube body
There is injecting adaptor, the top of the injecting adaptor is provided with syringe needle, and the outside of the syringe needle is provided with needle cap.
Preferably, the top of the push rod cup is provided with annular groove, seals snare inside annular groove.
Preferably, the syringe needle is made of needle holder and needle body, and needle holder, at bending, be open squarely, and opening is set
It is equipped with gradient.
Preferably, the injecting adaptor is bending, and the end setting of injecting adaptor is gradient.
Compared with prior art, the utility model has the beneficial effects that injecting adaptor is arranged to be bent by the utility model
Shape, injection tubular body highly pressurised liquid is to the thrust direction of syringe needle to side direction, when syringe needle is covered with needle holder is combined not tight, needle
Head is injected the power that highly pressurised liquid provides in pipe and projects, and the syringe needle of injection will not be flown nonstop to away, does not have lethality, to surrounding
People or object will not constitute harm.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~6, in the utility model embodiment, a kind of safety injector, including push rod pedestal 1, push rod 2, note
Tube body 4, sealing ring 6, injecting adaptor 7, syringe needle 8 and needle cap 9 are penetrated, the top of the push rod pedestal 1 is fixedly connected with push rod 2,
The top of the push rod 2 is connected with push rod cup 5, and the outside of the push rod cup 5 is provided with sealing ring 6, and sealing ring 6 can increase interior
Portion's air pressure, and the outside of sealing ring 6 is provided with injection tube body 4, the lower part of the injection tube body 4 is fixedly installed the low side of injection-tube
3, the top of the injection tube body 4 is fixedly installed injecting adaptor 7, and the top of the injecting adaptor 7 is provided with syringe needle 8, described
The outside of syringe needle 8 is provided with needle cap 9, and the top of the push rod cup 5 is provided with annular groove, and 6 sets of sealing ring in annular groove
Inside, the syringe needle 8 are made of needle holder 10 and needle body 11, and needle holder 10, at bending, be open squarely, and opening is provided with
Gradient, the injecting adaptor 7 is bending, and the end setting of injecting adaptor 7 is gradient.
The working principle of the utility model is: the equipment is when in use, needle holder 10 is rotatably fixed to injecting adaptor 7
The end setting of end, injecting adaptor 7 is gradient, injecting adaptor 7 and syringe needle 8 can be made to contact even closer, prevent syringe needle 8 from sending out
