Pipe, it may be necessary to twice or when can just be expelled to target vascular site more times, like this increase patient and injecting
When the pain to be born, while also increase the pressure of medical worker, more likely trigger family numbers of patients and medical worker it
Between dispute.
In addition, the vaccine injection of minor especially infant is more universal, the pain resistance of infant is weaker, blood
Pipe also relatively look for by difficulty, and now, multiple injection can more increase the pain of infant.
The content of the invention
The present invention be in order to solving the above problems and carry out, and it is an object of the present invention to provide a kind of injection needle, for injection
Needle tubing is supported the use, and patient is injected.
The invention provides a kind of injection needle, have the feature that, including：Injection needle body, containing needle point and
From the needle body of needle point extension；And anaesthetic layer, at least it is coated on needle point.
In injection needle provided by the invention, it can also have the feature that：Wherein, needle body and needle point are using not
What steel material of becoming rusty was integrally formed, anaesthetic layer is also coated on the outer surface of needle body.
In injection needle provided by the invention, it can also have the feature that：Wherein, anaesthetic layer is by benefit card
Because what is formed, one kind in Ropivacaine, Bupivacaine and totokaine.
In injection needle provided by the invention, it can also have the feature that, in addition to：Nesting part, wherein, it is nested
Portion is arranged on one end of the remote needle point of needle body, for being nested in injection needle.
In injection needle provided by the invention, it can also have the feature that：Wherein, nesting part in rectangular-shape or
It is cylindric.
Present invention also offers a kind of syringe, have the feature that, including：Injection needle, for accommodating decoction, tool
There is medicine liquid outlet；And injection needle, match with injection needle, be set on medicine liquid outlet, wherein, injection needle is above-mentioned
Injection needle.
In syringe provided by the invention, it can also have the feature that, in addition to：Protection sleeve pipe, wherein, protection
Sleeve pipe is set on injection needle, for being protected to injection needle.
In syringe provided by the invention, it can also have the feature that：Wherein, protection sleeve pipe be by polyethylene,
One kind in polypropylene, polyurethane, polyvinyl chloride and polytetrafluoroethylene (PTFE) and formed.
The effect of invention and effect
According to injection needle involved in the present invention, because being coated with anaesthetic layer on the surface of needle point, the present invention
Injection needle needle point and human body skin contact when, anaesthetic layer can discharge anaesthetic, to human body be injected place carry out
Local anaesthesia, such words can reduces suffered pain of the human body in injection process, while can also reduce medical worker
Pressure.
Brief description of the drawings
Fig. 1 is the structural representation of syringe in embodiments of the invention；And
Fig. 2 is the structural representation of injection needle in embodiments of the invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, it is real below
Example combination accompanying drawing is applied to be specifically addressed injection needle of the present invention and syringe.
Fig. 1 is the structural representation of syringe in embodiments of the invention.
As shown in figure 1, syringe 100 be used for patient is injected, including injection needle 10, injection needle 20, with
And protection sleeve pipe 30.
Injection needle 10 is used to accommodate decoction, has medicine liquid outlet 11, graduation mark is additionally provided with injection needle 10.
Injection needle 20 is set on medicine liquid outlet 11.
Fig. 2 is the structural representation of injection needle in embodiments of the invention.
As shown in Fig. 2 injection needle 20 includes injection needle body 21, anaesthetic layer 22 and nesting part 23.
Injection needle body 21 includes needle point 211 and needle body 212.
Needle point 211 is used to be pierced into inside patient.
Needle body 212 extends from needle point 211, and is integrally formed with needle point 211 using stainless steel.
Anaesthetic layer 22 is coated on needle point 211 and on the outer surface of needle body 212.Anaesthetic layer 11 be by lidocaine,
One kind in Ropivacaine, Bupivacaine and totokaine and formed.In the present embodiment, anaesthetic layer 22 is by lidocaine
And sustained release component composition, sustained release component can ensure that lidocaine slowly discharges in the given time.
Nesting part 23 is arranged on one end of the remote needle point 211 of needle body 212, for being nested in medicine liquid outlet 11.It is nested
Portion 23 is in rectangular-shape or cylindrical shape.In the present embodiment, nesting part 23 is in cuboid, and four of the cuboid supply the side held
Towards sunken inside, it is easy to medical worker to hold.The material of nesting part 23 is by polyethylene, polypropylene, polyurethane, polychlorostyrene
One kind in ethene and polytetrafluoroethylene (PTFE) and formed.In the present embodiment, the material of nesting part 23 is polyethylene.
As shown in figure 1, protection sleeve pipe 30 is set on injection needle 20, and for being protected to injection needle 20, protection
Medical worker or patient are injected syringe needle 20 and stabbed.Protection sleeve pipe 30, be by polyethylene, polypropylene, polyurethane,
One kind in polyvinyl chloride and polytetrafluoroethylene (PTFE) and formed.In the present embodiment, the material of protection sleeve pipe 30 is poly- amino
Ethyl formate.
The use process of syringe 100 is：Medical worker to patient when injecting, when needle point 211 touches patient
Skin when, anaesthetic layer 22 starts slowly to discharge lidocaine, and the place being injected to patient carries out local anaesthesia, and injection terminates
When, extract syringe 100.
The effect of embodiment and effect
Injection needle according to involved by embodiment, because being coated with anaesthetic layer on the surface of needle point, this hair
During the skin contact of the needle point of bright injection needle and human body, anaesthetic layer can discharge anaesthetic, and the place being injected of human body is entered
