Abstract
The utility model relates to an elastic powder and injection preparation automatic-mixing and pouring injector. The revolving shell is provided with a triangle revolving bar, and the shell of the liquid medium bottle is provided with a spring column, and the inner wall with a helix top. The external side of the spring column is provided with spring. The spring column is provided with handspike of solution medium bottle internally. The handspike is provided with a triangle hollowness matching with the revolving bar. The lower edge is the helix top of the handspike matching with the helix top of the shell of the solution medium bottle. The terminal of the secondary gear limit groove of the revolving shell is provided with a blocking gap preventing reverse rotation. Users just need to rotate the shell to mix drugs, and rotate reversely to remove the shell of the solution medium bottle to inject muscle of patients or fill drug into transfusion bottles. The operation is convenient.
Description
Technical field
This utility model relates to a kind of medical elastic press type powder injection automatic medicine-mixing pre-encapsulated injector.
Background technology
The applicant once applied for one " automatic injection powder mixing syringe " (application number: invention: 200510094419.9; Utility model: 200520075580.7), it is that the solute bottle is assembled in overcoat separately with the solvent of pressurization is bottled, and the turn rotary sleeve makes menstruum mix with solute by syringe needle, then human body is injected.This syringe has significantly reduced doctor, nurse's operation sequence and labor intensity, has also reduced contamination of heavy simultaneously, is fit to very much to vigorously promote the use.But what this syringe used is the solvent bottle of pressurization, also has some unsatisfactory parts in fill, transportation, preservation.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the deficiencies in the prior art, and a kind of structure perfect elastic press type powder injection automatic medicine-mixing pre-encapsulated injector more rationally is provided.
Technical solution of the present utility model is: the container of fill solvent uses the cassette bottle, utilizes spring assembly that the solvent under the normal pressure is compressed into the solute bottle.
Technological improvement of the present utility model is: be provided with solvent bottle push rod in solvent bottle upper end, the push rod front end is provided with the spiral mouth, and the solvent bottle is arranged with spring strut outward, and the outside is provided with spring, the rotary sleeve upper end is provided with swingle, and the second gear pushing sleeve stopper slot terminal of rotary sleeve is provided with anti-revolution bayonet socket.
The good effect that this utility model produced is: because the solvent bottle has used the cassette bottle, utilize the pressure of spring assembly that solvent is compressed into the solute bottle, the solvent bottle does not need precharge pressure, there is not the restriction of direction during operation, can be owing to pressure leakages causes solvent residue and the excessive bottle explosion that causes of pressure, also easier enforcement in the process of medicine fill yet.The second gear pushing sleeve stopper slot terminal of rotary sleeve is provided with anti-revolution bayonet socket, the operate miss in can effectively preventing to use.

The specific embodiment
As shown in Figure 1, rotary sleeve 9 of the present utility model is provided with leg-of-mutton swingle 25 (referring to Fig. 2), in order to prevent that spring 27 from lateral bending taking place in the process of upspringing, solvent bottle overcoat 8 is provided with spring strut 26, inwall is provided with solvent bottle overcoat spiral mouth 30 (referring to Fig. 3), spring strut 26 outsides are provided with spring 27 (referring to Fig. 3), spring strut 26 inside are provided with solvent bottle push rod 28, solvent bottle push rod 28 is provided with leg-of-mutton hollow 33, swingle 25 puts in solvent bottle push rod 28 and is provided with leg-of-mutton hollow 33 inside, the lower edge has solvent bottle push rod spiral mouth 31 (referring to Fig. 4) to match with solvent bottle overcoat spiral mouth 30, and the terminal of the second gear pushing sleeve stopper slot 23 of rotary sleeve 9 is provided with anti-revolution bayonet socket 32 (referring to Fig. 5).
In use, turn rotary sleeve 9, such one grade of pushing sleeve stopper slot 22 (referring to Fig. 4) drives one grade of pushing sleeve location stuck point 12 rotation, one grade of pushing sleeve 5 is moved downward, with pin medicated cap 13 to pressing down, make the bayonet socket 25 (referring to Fig. 5) of pin medicated cap 13 stick into solute bottle overcoat bayonet socket 16, pin medicated cap 13 drives syringe needle 4 and moves downward, make an end of syringe needle 4 puncture solute bottle plug 14, continue turn rotary sleeve 9, second gear pushing sleeve stopper slot 23 (referring to Fig. 4) drives stuck point 11 rotations of second gear pushing sleeve location, making second gear pushing sleeve 6 drive solvent bottle 7 moves downward, make the other end of syringe needle 4 puncture solvent bottle plug 10, in the time of turn rotary sleeve 9, swingle 25 drives solvent bottle push rod 28 simultaneously and rotates, after the other end of syringe needle 4 punctures solvent bottle plug 10, solvent bottle push rod spiral mouth breaks away from solvent bottle overcoat spiral mouth, spring 27 is upspring at once, solvent bottle push rod is pressed in downwards on the solvent bottle piston 29, and compressing solvent bottle piston 29 is to lower slider, solvent in the solvent bottle 7 is injected in the solute bottle 3 by syringe needle 4, mix with solute.This moment, second gear pushing sleeve location stuck point 11 had been moved to the end of second gear pushing sleeve stopper slot 23, the opposite spin rotary sleeve, second gear pushing sleeve location stuck point 11 promptly sticks into the anti-revolution bayonet socket 32 (referring to Fig. 5) that is located at second gear pushing sleeve stopper slot 23 ends, rotary sleeve 9 promptly drives solvent bottle overcoat unitary rotation, make screw thread 17 and screw thread 18 turns between solvent bottle overcoat 8 and the solute bottle overcoat 2, solvent bottle overcoat 8 is screwed off, solvent bottle overcoat 8 is separated with solute bottle overcoat 2.The solute bottle is just the same with conventional injector with solute bottle overcoat, can clinically use, and both can carry out intramuscular injection to the patient, or gives the infusion bottle dosing.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to this utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
