Abstract
The utility model relates to a screw type prefilled and sealed syringe which is mainly formed by that an end cap (7) at the front end of a solvent bottle (6) which has the inner pressure is in threaded connection with a solute bottle (2), the center of a spacer (3) which is arranged at the middle of the solute bottle is provided with a double-sealed rubber plug (10), and the diameter of an internal thread of the solute bottle is larger than the external diameter of the solvent bottle. When the utility model is used, the solvent bottle is in screwed connection with the solute bottle for combination through the end cap, rubber plugs (5, 10) of the two bottles are pierced by a conducting needle (8) for conduction in the process of the screwed connection, the medicine mix is realized and the operation of filling the medicine into an infusion bottle can be conveniently realized.
Description
Technical field
This utility model relates to a kind of injector for medical purpose, is applicable to that particularly the intravenous drip injectable powder mixes, the rotary joint style pre-encapsulated injector of dosing.
Background technology
Pre-encapsulated injector is owing to its structural brand-new design, and the plurality of advantages in manufacturing, pack, transport, using is by numerous medical personnel and patient's acceptance and well received.The applicant also applied for the patent of several pre-embedding class syringes once, and they all have separately architectural feature and superiority separately, can solve some technical barriers really.But these several mostly is Contiuum type, and promptly the solvent bottle just is assembled in when dispatching from the factory with the solute bottle, and longer dimension is so exist certain inconvenience in packing, transportation.Major part all is provided with a piston in these patents in solute bottle, solvent bottle in addition, powder could be dissolved by promoting piston, the medicinal liquid that dissolves is released again, and degree is lower automatically.Some also will use the overcoat relative restraint.
Summary of the invention
The technical problems to be solved in the utility model is in order to overcome the deficiencies in the prior art, provides that a kind of packaging volume is little, automaticity is high, just the rotary joint style pre-encapsulated injector that solvent bottle and solute bottle are combined in use.
Realize that the above-mentioned purpose technical solution is: the end cap with intrinsic pressure solvent bottle front end is threaded with the solute bottle.
The further solution of present technique is: be provided with a partition in the middle of the solute bottle, the partition center is provided with the double-enclosure plug.The diameter of solute bottle female thread is greater than the external diameter of solvent bottle.
Structure of the present utility model is very simply but especially novel, rationally, just solvent bottle and solute bottle can be connected by the female thread of solute bottle and the external screw thread of end cap, operation technique is very easy.In the process of solvent bottle precession, just can make solvent bottle and the conducting of solute bottle mix medicine,, improve automatic degree and work efficiency by its intrinsic pressure medicinal liquid can being injected in the venous transfusion bottle by broken upper and lower two plugs of conducting acupuncture.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, this utility model mainly is made of solvent bottle 6, solute bottle 2, conducting pin 8 and syringe needle 12.Wherein, solvent bottle 6 is for having intrinsic pressure cillin bottle, is provided with external screw thread at the front end of solvent bottle 6, has plug 5 in the front end.The end cap 7 that has internal and external threads cooperates with the front end spiral of solvent bottle 6, and conducting pin 8 passes end cap 7 and thrusts in the plug 5.The intermediate radial of solute bottle 2 is provided with a partition 3, and being plugged with the cross section in the circular hole at partition 3 centers is I-shaped double-enclosure plug 10.Solute bottle 2 upper inside wall are provided with screw thread, can spin with the external screw thread of end cap 7.Also be provided with plug 13, sealing cap 1 in the lower end of solute bottle 2 with plug 13 sealing, the syringe needle 12 that has banking stop 11 is fixedlyed connected with sealing cap 1, and an end of syringe needle 12 stretches in the plug 13 but do not puncture.Said conducting pin 8 is the hollow body of double headed roller point, also is provided with a banking stop 9 on conducting pin 8.The upper end of this conducting pin 8 is stretched in the plug 5, and lower end aligned double-enclosure plug 10.
This syringe solvent bottle 6 when not using is isolating with solute bottle 2.If will use the time, the end cap 7 of the solvent bottle 6 front ends female thread by external screw thread and solute bottle 2 is spun, the two is combined into one.Syringe needle 12 is thrust in the infusion bottle, when continuation turn solvent bottle 6 made end cap 7 be threaded to the end of solute bottle 2 female threads downwards, conducting pin 8 will upwards pierce through plug 5 simultaneously and pierce through double-enclosure plug 10 downwards again.Owing to be filled with pressure in advance in the solvent bottle 6,, powder is fully dissolved or mix with water preparation so solvent will enter in the solute bottle 2 by conducting pin 8 under intrinsic pressure effect.Pressure is in poised state after two bottles of conductings, but still has pressure in two bottles, dissolves or mixed medicinal liquid is added in the infusion bottle so just can make under this pressure effect, promptly finishes once the operating process to the infusion bottle dosing.Reserve a segment distance between solute bottle 2 bottom surfaces and the sealing cap 1, this segment distance should be able to satisfy the needs that syringe needle 12 pierces through plug 13.When syringe needle 12 pierced through infusion bottle, owing to be subjected to counteracting force, the upper end of syringe needle 12 can be pierced through plug 13 simultaneously, and this moment, sealing cap edge, 1 end promptly contacted with the bottom surface of solute bottle 2.
This syringe is disposable use, with the back just not.Can be utilized once more, thus very high safety had, and easy to operate.
