Description
Technical field
A kind of medical equipment is the utility model is related to, it is espespecially a kind of to improve injection safety when surgical disease needs injection
Performance and the injector for medical purpose for reducing a kind of painful special high safety performance of surgery of injection.
Background technology
Surgery is the generation for studying surgical disease, the rule of development and its clinical manifestation, is diagnosed, the science of prevention and treatment,
It is the professional section office with surgery excision, repairing for means of mainly curing the disease.With the application of microsurgical technique, surgery obtained compared with
Big development, surgical disease are divided into five major classes：Wound, infection, tumour, deformity and dysfunction, surgical intervention are to usually require
Intramuscular injection is carried out, surgical pain was once one of an important factor for obstruction surgery develops, and U.S. Morton is used first within 1846
Ether assists Warren to be anesthetized with ether and has implemented many major operations as anesthetic,general.Since then, etherization just by
It is generally applicable to surgery.German Schleich in 1892 is advocated first makees local infiltration anesthesia with cocaine, but due to its toxicity
Height, replaced soon by procaine, Proca is carried on as before for safely and effectively local anesthetic so far.
Medical universal syringe is a kind of common medical instruments at present, generally by syringe needle, syringe and matching
Piston rod composition, using very extensive in medical and health industry.The syringe of surgery is exactly traditional syringe at present, is passed
The syringe of system is when in use, it is impossible to control the distance of puncture, i.e. distance in the needle point leading portion insertion body of syringe needle can not determine,
Experience and range estimation are leaned on entirely, is punctured apart from the too short or long therapeutic effect that can all have influence on patient, it is also possible to make some normal groups
Knit and receive injury, it is long if can also making patients pain, such as nerve or bone sustain damage, so need to puncture
Depth, which is done, accurately to be limited, and protects the health of patient；Conventional syringe is all that only a pitch brace is living with unification simultaneously
Chock plug is drawn and is vented, when exhaust can not totally bring kind of the medicine of injury, especially two to be used in mixed way injection to patient, sometimes
What can be arranged does not need secondary exhaust totally, spends the time.
The content of the invention
In order to improve injection safety performance and reduce injection pain, the utility model aims to provide one kind and can once grasped
A kind of medical injection for the special high safety performance of surgery for injecting paracentesis depth is completed to draw and is once vented and control twice
Emitter.
The technical solution adopted in the utility model is：A kind of injector for medical purpose of the special high safety performance of surgery, it is described
Syringe mainly includes syringe needle, syringe and pitch brace, and syringe is in hollow tubular, and syringe needle is removably mounted at syringe lower curtate, living
Fill in pull bar piston head end to be arranged on inside syringe, drag link end extension is arranged on outside syringe, and described pitch brace has sequentially
Lower two piston heads and coaxial inside and outside two pull bars, path pull bar are arranged on inside big footpath pull bar, big footpath pull bar and upper piston head
Connection, path pull bar are connected with lower piston head, and the protection ring of adjustable position is provided with described syringe needle.
Described big footpath pull bar stretchy upper piston head moves up and down inside syringe.
Described path pull bar stretchy lower piston head moves up and down inside syringe.
Described protection ring is fixed on outside syringe needle after can adjust the upper-lower position outside syringe needle.
Described protection ring is latex or plastic cement material.
It is carved with scale in described syringe needle top.
The beneficial effects of the utility model are：The utility model has inside and outside two pitch braces to control different pistons respectively
Head, when drawing two kinds of medicinal materials, the first can pull path pull bar to draw, and pull big footpath pull bar to draw second, arrange
Big footpath pull bar need to be only pressed during gas, it is so convenient to draw parenteral solution twice, safety collar, Ke Yifang are provided with outside syringe needle in addition
Just penetration depth during needle injection is controlled, protects patient, reduces the pain of patient, surgical patient is especially reduced and is carrying out hand
The pain injected in advance during art.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Accompanying drawing marks explanation：The big footpath pull bars of 1-, 2- path pull bars, 3- syringes, 4- syringe needles, 5- safety collars.
Embodiment
Embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings：
A kind of injector for medical purpose of the special high safety performance of surgery, described syringe mainly include syringe needle 4, the and of syringe 3
Pitch brace, syringe 3 are in hollow tubular, and syringe needle 4 is removably mounted at the lower curtate of syringe 3, and pitch brace piston head end is arranged on pin
Inside cylinder 3, drag link end extension is arranged on outside syringe 3, described pitch brace have sequentially lower two piston heads and it is coaxial in
Outer two pull bars, path pull bar 2 are arranged on inside big footpath pull bar 1, and big footpath pull bar 1 is connected with upper piston head, and big footpath pull bar 1 can be drawn
Dynamic upper piston head is moved up and down inside syringe 3, and path pull bar 2 is connected with lower piston head, the stretchy lower piston head of path pull bar 2
Moved up and down inside syringe 3, the protection ring of adjustable position, protection ring latex or plastic cement material are installed on described syringe needle 4
Matter, it is fixed on after can adjust the upper-lower position outside syringe needle 4 outside syringe needle 4, scale is carved with the described top of syringe needle 4.
The utility model has inside and outside two pitch braces to control different piston heads respectively, when drawing two kinds of medicinal materials, the
One kind can pull path pull bar 2 to draw, and pull big footpath pull bar 1 to draw second, need to only press big footpath pull bar 1 i.e. during exhaust
Can, it is so convenient to draw parenteral solution twice, safety collar 5 is provided with outside syringe needle 4 in addition, when can conveniently control the injection of syringe needle 4
Penetration depth, protect patient, reduce the pain of patient.
