Abstract
The utility model discloses a powder cartridge prefilled syringe. The syringe comprises a shell (2) and a plunger (1), and is characterized in that the a connecting body (3) arranged at the front end of the plunger (1) in the shell (2) has threads, and a piston (7) arranged at the tail end of a powder cartridge (9) also has threads. The inner diameter of an injection port (4) at the front end of the shell (2) is the same as the outer diameter of the mouth of the powder cartridge (9). During injection, a syringe needle (6) with a needle holder (8) is sleeved or screwed on the injection port and the syringe needle pierces a rubber plug of a pressure bottle (10). As the pressure bottle is prefilled with solvent and pressure, the solvent enters the power cartridge from the syringe needle under pressure to mix and dissolve medicine. Then the pressure bottle is removed and the plunger is pushed to make the piston press liquid medicine so as to inject the liquid medicine into the human body. The utility model has the advantages of extremely simple structure and convenient use, and is particularly suitable for clinical use in hospitals.
Description
Technical field
This utility model relates to the pre-embedding injection device of a kind of injectable powder cassette bottle.
Background technology
The applicant repeatedly applied for multiple pre-embedding injection device once, and they all have separately function and purposes.But some pre-embedding injection device mostly is that the solvent bottle is linked together by conduction pipe and solute bottle, can't change separately or multiple being used in combination, and still there are some problems in use in very flexible, makes troubles for clinical use.
Summary of the invention
The technical problems to be solved in the utility model is exactly in order to overcome the deficiencies in the prior art, and a kind of pre-embedding injection device of injectable powder cassette bottle simple in structure, easy to use, with low cost is provided.
Technical solution of the present utility model is:
The pre-embedding injection device of this injectable powder cassette bottle comprises shell and push rod, is positioned on the connector of push rod front end of shell to have screw thread, also is provided with screw thread and be positioned on the piston of cassette powder pin bottle tail end.
Further technical solution of the present utility model is:
The longitudinal profile of the connector of push rod front end can be T font structure.
Also can be the T-slot that matches with T shape connector in the said piston.
The internal diameter of shell front end injection port is identical with the external diameter of cassette powder pin bottle bottleneck.
Can connect one by the hinge or the body that is flexible coupling on shell renovates.

The specific embodiment
Fig. 1 shows structure of the present utility model.It has the shell 2 of a cylindrical tube shape, and the front end of shell 2 is provided with an injection port 4 that is hollow cylinder, has the push rod 1 that pushes away handle and is positioned at shell 2, and the Front-end Design of push rod 1 has a connector 3, is provided with screw thread on the outer circumference surface of connector 3.
Fig. 2 has shown the configuration state when this utility model is used.During use, earlier push rod 1 is extracted out fully, a front end is had plug 5 and tail end has the cassette powder pin bottle 9 of rubber piston 7 and puts into shell 2, and the front portion of cassette powder pin bottle 9 is stretched in the injection port 4 of shell 2.Then with the connector 3 of push rod 1 by in the screw thread that is threaded into piston 7, realize the connection of the two.
Said connector 3 also can be made into the T shape connector 3.1 that longitudinal profile is a T font structure, and also can be made into the T-slot 14 that matches with T shape connector 3.1 in the piston 7.Because of piston 7 is made by rubber-like rubber, firmly T shape connector 3.1 is pushed the connection that just can realize the two in the T-slot 14 (referring to Fig. 6).
When needing injection, an entry needle 6 that has punch block 8 is enclosed within or is screwed on the injection port 4, entry needle 6 is pierced through the plug of pressurized bottle 10.Because be filled with solvent and pressure in advance in the pressurized bottle 10, solvent will enter in the cassette powder pin bottle 9 by entry needle 6 under the effect of pressure, realize mixing the molten medicine of medicine.Take out pressurized bottle 10 then and promote push rod 1, make piston 7 compressing medicinal liquids, medicinal liquid can be injected in the human body after the aerofluxus.
This utility model also can be made shell 2 as Fig. 3, Fig. 4 and two and half shells shown in Figure 5, renovate 13 and be connected with shell 2 by the hinge or the body 12 that is flexible coupling, with the hinge or the body 12 symmetric opposite sides that are flexible coupling renovate 13 and shell 2 on be equipped with card button 11.Open and renovate 13 and just cassette powder pin bottle 9 can be put into shell 2, cover then renovate 13 and make renovate 13 and shell 2 on card button 11 block mutually, just can implement injection according to aforesaid method of operation in operation again to human body.
Claims (5)
