Description
Technical field
This utility model belongs to technical field of medical instruments, relates to the pre-embedding powder of a kind of non-intestinal needle injection.
Background technology
Existing injectable powder pre-encapsulated injector all be the pre-embedding of powder injection formulation in the cassette bottle, water for injection is loaded in the cillin bottle, and in cillin bottle, be filled with the gas of certain pressure, this syringe all uses special process production separately in actual production, technical difficulty is quite big, production cost is very high, owing to be filled with the gas that has certain pressure in the cillin bottle, so transportation, preservation and the use of product all had specific (special) requirements.In actual use, product quality is wayward, poor reliability, owing to need special process to produce medicine, so, can not the existing powder injection formulation in supporting use market, must change the existing pharmaceutical packing form of having gone on the market could use, and therefore, its scope of application is greatly limited.
Summary of the invention
The purpose of this utility model provides the pre-embedding powder of a kind of non-intestinal needle injection, can be directly and the supporting use of the existing powder injection formulation in market, and simple in structure, be easy to produce.
The technical scheme that this utility model adopted is, the pre-embedding powder of a kind of non-intestinal needle injection, comprise the cassette bottle, end at the cassette bottle is provided with piston, the other end of cassette bottle is provided with bottle cap, pre-installs water agent for injecting in the cassette bottle, and the piston one end bottle periphery of described cassette bottle is fixed with the injection handle, the injection handle is connected with push rod, and push rod passes the injection handle and contacts with piston; On the bottle cap of cassette bottle, be connected with slide lid, be fixed with the twolip syringe needle on the slide lid, bottle cap one end bottle periphery at the cassette bottle is fixed with fixed sheath, the coaxial socket of an end of fixed sheath and movable sheath, and the other end opening of movable sheath also is connected with cillin bottle.
Characteristics of the present utility model also are:
The excircle of fixed sheath is provided with the twice indenture.
Movable sheath is towards the corresponding twice convex epirelief that is provided with the twice indenture of inner surface of fixed sheath, movable sheath is symmetrically arranged with six salient points towards an end inner surface of cillin bottle along circumference, the circumferential direction inside of movable sheath is provided with a boss, and the internal diameter of boss is less than the external diameter of slide lid.
The beneficial effects of the utility model are, do not need to change existing listing drug packaging form, can be directly and the supporting use of the existing powder injection formulation in market, and simple in structure, its production cost reduces greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model fixed sheath and movable sheath embodiment;
Fig. 3 is the work sketch map of this utility model device.
Among the figure, 1. push rod, 2. injection handle, 3. cassette bottle, 4. fixed sheath, 5. movable sheath, 6. cillin bottle, 7. powder injection formulation, 8. salient point, 9. twolip syringe needle, 10. convex epirelief, 11. boss, 12. slide lids, 13. indentures, 14. pistons.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.Comprise cassette bottle 3, end at cassette bottle 3 is provided with piston 14, the other end of cassette bottle 3 is provided with bottle cap, pre-install water agent for injecting in the cassette bottle 3, the piston one end bottle periphery of cassette bottle 3 is fixed with injection handle 2, injection handle 2 is connected with push rod 1, and push rod 1 passes injection handle 2 and contacts with piston 14; On the bottle cap of cassette bottle 3, be connected with slide lid 12, be fixed with twolip syringe needle 9 on the axle center of slide lid 12, bottle cap one end bottle periphery at cassette bottle 3 is fixed with fixed sheath 4, the coaxial socket of one end of fixed sheath 4 and movable sheath 5, movable sheath 5 and twolip syringe needle 9 concentrics, the other end opening of movable sheath 5 is connected with XiLin bottleneck.
Fig. 2 is the structural representation of this utility model fixed sheath and movable sheath embodiment.The excircle of fixed sheath 4 is provided with twice indenture 13, movable sheath 5 is provided with twice convex epirelief 10 towards the inner surface and indenture 13 correspondence positions of fixed sheath 4, movable sheath 5 is symmetrically arranged with six salient points 8 towards an end inner surface of cillin bottle along circumference, is used for fixing cillin bottle.The circumferential direction inside of movable sheath 5 is provided with a boss 11, and the internal diameter of boss 11 is less than the external diameter of slide lid 12.
Fig. 3 is a work sketch map of the present utility model.During use, the bottleneck of cillin bottle 6 is snapped in salient point one end of movable sheath 5, move on one side to cassette bottle 3 with cillin bottle 6 compressing activity sheaths 5, when movable sheath 5 all is inserted in fixed sheath 4, twice convex epirelief 10 just in time blocks with twice indenture 13, the boss 11 of movable sheath 5 just pushes slide lid 12 bottle cap of cassette bottle 3 is compressed, cillin bottle 6 enters salient point 8 and is fixed by salient point 8 with interior, twolip syringe needle 9 thrusts in the cassette bottle 3 at this moment, meanwhile twolip syringe needle 9 thrusts in the cillin bottle 6, realized being communicated with of cassette bottle 3 and cillin bottle 6, promoting piston 14 enters in the cillin bottle 6 water preparation, realize the abundant mixing of water preparation and powder injection formulation 7, then medicine is sucked back cassette bottle 3, catch movable sheath 5 to unplug cillin bottle 6, because it is firm that boss 11 makes twolip syringe needle 9 be connected with cassette bottle 3, therefore twolip syringe needle 9 can not become flexible, and more movable sheath 5 is taken away from fixed sheath 4, can carry out injection operation.
This utility model manufacturing simple in structure, easy, be applicable to the powder injection formulation of all veins and intramuscular administration clinically, during with the supporting use of existing preparation, do not need to change the packaged form of existing powder, do not need to apply for again the pharmaceutical production authentication code, production cost reduces greatly, has excellent adaptability.
