Abstract
The invention discloses a kind of ejection type medicament injection apparatus, it includes the ejection type medicament injection apparatus of the compositions such as shell, launching cradle, pull rod, fixed link, power spring, circlip, injection key, housing hollow, launching cradle cavity, asepsis injector.Its main feature is that, the asepsis injector on launching cradle is placed under the action of power spring, it is moved downward along fixed link, asepsis injector syringe needle can be accurately pierced into the position of needed by human body injection drug, push asepsis injector push rod, it can be by drug injection into human body, having achieved the purpose that inject drug, thus with mechanical ejection device instead of manual operation.Ejection type medicament injection apparatus of the invention can provide a kind of professional and layman and handicapped patient and can operate, and the asepsis injector by more renewing, i.e., injectable it is all can injection drugs.
Description
The present invention relates to a kind of ejection type medicament injection apparatus, especially by shell, launching cradle, pull rod, fixed link, power
The ejection type medicament injection apparatus of the compositions such as spring, circlip, injection key, housing hollow, launching cradle cavity, asepsis injector.
After people's illness, over the course for the treatment of, it is sometimes desirable to carry out injection of drug, this sterile note with asepsis injector
The operation of emitter is all to be completed by doctor professional in hospital, nurse's manual operations, and even professional operates at present
Be be easy to cause injection inserting needle depth, inject the angle of inserting needle, the position for injecting inserting needle deviates, and layman by
In the study and training that did not receive profession, it is difficult to complete this operation, dare not also carries out this operation.
Currently, " insulin pen injectors " available on the market are made of pen cap, pen core, syringe needle, mechanical device etc., but
It is that " insulin pen injectors " can only inject micro single drug, and cannot inject large dosage and different types of drug,
" insulin pen injectors " are somebody's turn to do when the syringe needle that its is extremely short is pierced into human body, it is still necessary to manual operations.
The purpose of the present invention is to provide a kind of professional and laymans and handicapped patient to grasp
Make, and the asepsis injector by more renewing, injects all drugs that can be injected, make patient without going to hospital that can reach injection
Drug carries out the purpose for the treatment of disease.
It, should the purpose of the present invention is being realized and providing a kind of ejection type medicament injection apparatus having the following structure
Ejection type medicament injection apparatus is by shell, housing hollow, launching cradle cavity, launching cradle, pull rod, fixed link, power spring, card
Spring, injection key, asepsis injector composition；There is a shape similar on the housing wall but is greater than the cavity of asepsis injector；Shell
There are two strip slots for the two sides of body upper end, and shell side corresponding position is equipped with injection key, the launching cradle, fixed link, power
Spring is loaded on enclosure interior and generally on straight line, and the launching cradle can move up and down, on the launching cradle
Hold wing corresponding position there are two pull rod, the launching cradle cavity is interior to be provided with two circlips.
Compared with the prior art ejection type medicament injection apparatus of the invention has the advantages that the nothing being placed on launching cradle
Bacterium syringe moves downward under the action of power spring along fixed link, asepsis injector syringe needle accurately can be pierced into human body
The position of required injection drug, to make the depth of asepsis injector injection inserting needle instead of manual operation with mechanical ejection device
Degree, injects the angle of inserting needle, injects the position of inserting needle in controllable range, improves the quality of drug injection operation,
And due to easy to operate, ordinary person can also be operated, it is not necessary to which Zai Qu special environment implements this operation.
Embodiments of the present invention are described below with reference to accompanying drawings.
Attached drawing 1 is cross-sectional view of the invention.
Attached drawing 2 is sectional view of the invention.
The top of shell 2 is provided with handle 13, and the side of shell 2 is provided with a housing hollow 15, housing hollow 15
Shape is similar to 3 shape of asepsis injector, but is greater than the shape of asepsis injector 3, and launching cradle 8 is intermediate tubular upper and lower ends band
There is the ejection frame end wing 9, the edge of the ejection frame end wing 9 has four ejection frame end foramen alares 4, launches the diameter of frame end foramen alare 4
Greater than the diameter of fixed link 6,8 frame of launching cradle is as tubular, in the tubular frame body of launching cradle 8 and the corresponding position of housing hollow 15
Also it is provided with launching cradle cavity 16, the shape of launching cradle cavity 16 is similar to 3 shape of asepsis injector, but is greater than asepsis injector 3
Shape, the aperture of power spring 11 is greater than the diameter of fixed link 6, and two fixed links 6 are worn from ejection frame end foramen alare 4 respectively
It crosses, is then passed through the inner hole of power spring 11, then the upper and lower ends of fixed link 6 are separately fixed to the upper and lower ends of shell 2.
Two handles 13 are respectively provided at the ejection frame end wing 9 of launching cradle 8, in pull rod 10 and 2 corresponding position of shell, i.e.,
The upper end of shell 2 is provided with strip slot 12, and pull rod 10 is stretched out from strip slot 12, and 2 corresponding position of shell is provided with injection key
5, make asepsis injector 3 be convenient for being fixed to corresponding position, when injection presses injection key 5, makes launching cradle 8 in power spring 11
Under effect, launching cradle 8 is pushed to move downward, the inside of launching cradle cavity 16 is provided with two circlips 7.
In use, working as the asepsis injector 3 for filling drug via housing hollow 15, launching cradle cavity 16 is placed into launching cradle
8 inside, and it is fixed by the circlip 7 inside launching cradle cavity 16, pull rod 10 is pulled up, compresses launching cradle 8 during pull-up
Launching cradle 8 can be fixed on corresponding position by power spring 11, injection key 5, by the lower end of the ejection type medicament injection apparatus,
It is exactly one end with asepsis injector syringe needle 1, injection key 5, ejection are pressed in the position for needing to inject after alignment human body is sterilized
Frame 8 can move downward under the action of power spring 11, while drive the asepsis injector syringe needle 1 above launching cradle 8, penetrate into people
Body needs the position injected, and pushes asepsis injector core bar 14, the drug in asepsis injector 3 is slowly injected into human body, completes
After drug injection, ejection type medicament injection apparatus can firmly be driven into aseptic injection to the opposite direction pin at human injection position
