Utility model content
For the problems referred to above, the purpose of this utility model there is provided the dual chamber syringe for injecting high viscosity medicament, solve described thrust when injecting high viscosity medicament excessive, or injector length is excessive, the technical problem of the use difficulty caused.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, for injecting the dual chamber syringe of high viscosity medicament, for injecting full-bodied injection material, comprises cylindric injection tube, push rod, entry needle.
One end of injection tube is provided with opening, and injection material is entered in injection tube by opening.Described injection tube and the rightabout one end of described opening are provided with outer cone joint, and described entry needle is connected with female cone joint, and described injection tube is connected with female cone joint by outer cone joint with entry needle.
Injection tube middle position is provided with next door, and described next door extends to outer cone joint along injection tube central axis direction from described opening, two cavitys being divided into shape identical with structure injection tube.Described cavity is provided with along injection tube inner surface locking groove outwardly away from one end of outer cone joint.
The structure inserting two push rods of described two cavitys is respectively identical.Push rod also comprises push rod cup, and described push rod is provided with the first lock ring matched with described locking groove near push rod cup place, and push rod is provided with the second lock ring matched with described locking groove away from push rod cup place.Described first lock ring, the second lock ring are the annular protrusion structure around push rod, coordinate with locking groove, the position of fixing push rod.
During concrete use, be all full of injection material in cavity, push rod is positioned at home position, and push rod extends described cavity.Described locking groove fixes the first lock ring of push rod, prevents push rod from skidding off.
Promote described push rod, the injection material in cavity is squeezed to entry needle.After injection material enters entry needle completely, described locking groove fixes the second lock ring of push rod, and anti-throw-out lever moves ejection cavity.
As preferably, described push rod is semi-circular cylindrical.
This utility model structure is simple, while arranging two cavitys minimizing injector length, increases the capacity of syringe, solves the inconvenience brought when using general injector to inject high viscosity medicament.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
For injecting the dual chamber syringe of high viscosity medicament, for injecting full-bodied injection material 401, comprise cylindric injection tube 101, push rod, entry needle 104.
Consult Fig. 1, one end of injection tube 101 is provided with opening, and injection material 401 is entered in injection tube 101 by opening.Described injection tube 101 is provided with outer cone joint with the rightabout one end of described opening, and described entry needle 104 is connected with female cone joint, and described injection tube 101 is connected with female cone joint by outer cone joint with entry needle 104.
Injection tube 101 middle position is provided with next door 301, and described next door 301 extends to outer cone joint along injection tube 101 central axis direction, injection tube 101 is divided into the first cavity 302 and the second cavity 303 of same shape and structure.First cavity 302 is provided with along injection tube 101 inner surface locking groove 403 outwardly away from one end of outer cone joint.
