Description
Technical field
The utility model is related to arrive various injector for medical purpose, various disposable sterilized syringes are related specifically to, more
It is related specifically to various safety-type disposable sterilized syringes.
Background technology
Various injector for medical purpose can be used for injecting and export various liquid, can be used for aspirating various liquid, may be used also
For being mixed various liquid or mixing various liquid with powder, pumping liquid or mixing in container can be also used for
Various liquid or mixing liquid and powder can be also used for flushing or cleaning of objects.It is plugged on the conehead of various injector for medical purpose
After injection needle, various medicaments can be injected into human body or the subcutaneous of animal, muscle, blood vessel or other histoorgans, also
Various liquid can be aspirated out of human body or the histoorgan of animal.After fog-spray nozzle being plugged on the conehead of various injector for medical purpose,
Various medicaments can be sent forth on the mucous membrane or other histoorgans of human body or animal.
Well known routine injector for medical purpose includes housing and core bar.It is cased with enough transparencies outside.It is cased with housing cavity outside.
The housing cavity end opening before and after housing respectively.There is back cover portion in the front end of housing cavity.Before the back cover portion of housing cavity
There is conehead at end.The conehead of housing can be outer cone connector, or outer cone locked joints.During the conehead of housing can be
The conehead of hair style, or the conehead of inclined hair style.There is cone head hole in conehead.Cone head hole is penetrated through with housing cavity.In housing
There is housing crimping at rear portion.There is volume scale on the outer surface of housing.The rear end of core bar has by hand, and there is sealing ring in front.Core bar
Sealing ring be inserted into housing cavity from housing cavity open rearward end after, manipulate core bar by hand can make sealing ring housing sky
Intracavitary is moved forward and backward, and the sealing that the outer wall of sealing ring forms injector for medical purpose with the inner wall of housing cavity coordinates.
The first unsatisfactory place of conventional injector for medical purpose is, in one-handed performance to disposable aseptic injection
It is susceptible to error when injection liquid in device, gas especially in Inside Syringe or mixes various liquid or by various liquid
When body is mixed with powder, needs to inject repeatedly and liquid jet, one-handed performance are more difficult.Second of unsatisfactory place be,
After disposable sterilized syringe use, the injection needle to carry disease germs is exposed outside, easily causes serious infection to injure human body,
Also, since syringe needle engages with the conehead of the housing of syringe tighter, both hands shed syringe needle and return the dynamic of set sheath closure syringe needle
Work is to cause medical staff that the most high-risk action that needle is stabbed occurs.World Health Organization WHO reported just have for every 30 seconds in 1999
One medical staff is contaminated syringe needle and stabs.The third unsatisfactory place is, disposable sterilized syringe and with shield
The injection needle of set is separated in packing box；It needs first to take out syringe from packing box when in use, then shield will be carried
The injection needle of set takes out from packing box, installs injection needle on the injector after then removing sheath；After use, need by
Injection needle is removed from syringe, then is found sheath and entangled injection needle, or the note directly with sheath by installation on the injector
It penetrates needle guard to live, human body is injured to prevent exposed injection needle；Whole operation process is cumbersome, also easily causes to hinder to user of service
Evil.
United States Patent (USP) US20120296277A1, US20150174339A1, US20150314079A1,
The various safety-type disposable sterilized syringes introduced in US20160008554A1 and US20160271340A1, are using
Afterwards, the injection needle to carry disease germs is taken in the housing cavity of syringe using various methods, the injection needle to carry disease germs is avoided to make human body
At serious injury.The first unsatisfactory place of above-mentioned various injector for medical purpose is safety-type disposable sterile note
The part of emitter is more more more complicated than the part of conventional disposable sterilized syringe, and the overall volume of injector for medical purpose is more
Greatly, assembly is also more difficult, therefore production cost wants much higher.Second of unsatisfactory place of above-mentioned various injector for medical purpose
It is that the chamber that fills of safety-type disposable sterilized syringe has multiple parts, when filling liquid is difficult to complete Inside Syringe
The gas for filling chamber, can human body intravascular generation aeroembolism, human body is damaged.Above-mentioned various injector for medical purpose
The third unsatisfactory place be that after safety-type disposable sterilized syringe use, most of core bar stretches out housing, shape
It is larger at the overall volume after using, it makes troubles to subsequently destroying.The 4th kind of above-mentioned various injector for medical purpose makes us
Dissatisfied place is to be clearance fit between the injection needle and housing of safety-type disposable sterilized syringe, will disposably make
With the injection of asepsis injector be needled into human body muscle and it is intravascular when, the needle point of injection needle is easy to happen swing, causes to grasp
It slips up.
By above-mentioned it will be clear that well known injector for medical purpose also needs to be improved further so that injector for medical purpose
Production cost it is lower, injector for medical purpose convenience more secure when used, injector for medical purpose is more easy to destroy after.
Utility model content

Utensil intracavitary；In injector for medical purpose by use, being placed into the utensil intracavitary of core bar in pinching by the indentation, there of hand for core bar
The taper lip of instrument used for injection takes out instrument used for injection from the lateral openings of utensil chamber；After injector for medical purpose is used, it will insert
After instrument used for injection on the conehead of housing is removed, then instrument used for injection is disposed from the lateral openings of utensil chamber to the utensil into core bar
Intracavitary, most of core bar enters in housing after then shifting core bar onto bottom, reaches finally formed safety-type injector for medical purpose
The smaller purpose of overall volume, to offer convenience to subsequently destroying.
The injector for medical purpose of the utility model realizes the part of the safety-type injector for medical purpose of the utility model than conventional by one
Secondary property lacks the part of the sheath of an injection needle, the filling liquid of the safety-type injector for medical purpose of the utility model using asepsis injector
The structure of chamber is identical as conventional disposable sterilized syringe, and the safety-type injector for medical purpose of the utility model both reached
Convenient for excluding to fill the gas of chamber and convenient for the purpose of assembly, and reach production cost and conventional disposable sterile note
The production cost of emitter is similar, and the mesh more much lower than the production cost of existing safety-type disposable sterilized syringe
's.
It will thus be seen that above-mentioned stated target, including by those of shown target described above by effectively
Reach.Described here is only the typical best form of implementation of the present utility model application, can make certain to above structure
A little variations are also without prejudice to the spirit and scope of the utility model.The utility model is not limited to tool set forth herein
Body details, and should retain as stated in the restriction of claim for fields secondary technology personnel be it is aobvious and
Any improvement being clear to or remodeling.
