In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Fig. 1-fig. 3 show a controllable type double-nipple injector, including injection tube 1, push rod 2 (the bottom is connected with the piston), first syringe needle 3, hose 4, second syringe needle 5, valve body 6, handle 7, valve port 8, gag lever post 9, seal ring groove 10, first nipple 11, second nipple 12 and axle through mouth 13.

Wherein, two liquid outlets are formed at the bottom of the injection tube 1, a first nipple 11 is arranged at one liquid outlet, a second nipple 12 is arranged at the other liquid outlet, and the second nipple 12 is communicated with a second needle head 5; the valve structure is installed in cooperation with the two nipples.

The utility model discloses a method of use as follows, when clinical preparation needs the powder infusion medicine that dissolves, during the use, the step as follows:

firstly, the valve handle is rotated to open the liquid passage corresponding to the second nipple 12, close the passage corresponding to the first nipple 11, insert the needle connected with the second nipple 12 into the injection port of the solution bottle, and extract the solution as required.

Then, the valve handle is rotated so that the liquid passage corresponding to the first nipple 11 is opened and the liquid passage corresponding to the second nipple 12 is closed.

And (III) inserting the needle connected with the first nipple 11 into an injection port of the powder medicine bottle, pushing the push rod 2, injecting a solution through the needle connected with the first nipple 11, dissolving the powder medicine, and sucking the medicine to be injected.

And (IV) adjusting the valve structure to close the liquid passage corresponding to the first nipple 11 and open the liquid passage corresponding to the second nipple 12, and pushing the push rod 2 to inject the medicine to be injected into the solution bottle.

And (V) extracting the solution according to the requirement, and rotating the handle to open the liquid passage corresponding to the first nipple 11 and close the liquid passage corresponding to the second nipple 12.

And (VI) pulling out the needle connected with the first nipple 11 from the powder medicine bottle, inserting the needle into an injection port of another powder medicine bottle, pushing the push rod 2, injecting solution through the needle connected with the first nipple 11, dissolving the powder medicine, and sucking the medicine to be injected.
