The medicine guiding groove is vertically opened in the middle of the adapter body. The inner diameter of the medicine guiding groove gradually decreases from the bottom to the head. The external thread is opened on the outside of the head of the adapter body;

[0007] The second adapter mechanism: is used for adapting an ordinary syringe needle. The second adapter mechanism includes a connecting sleeve and an internal thread. The inner wall of the connecting sleeve is provided with an internal thread. The adapter body and the connecting sleeve are spirally connected through the external thread and the internal thread. The middle end of the head of the connecting sleeve is fixedly installed with a connecting head, and one end of the connecting head is communicated with the connecting sleeve.

[0008] Preferably, a limiting platform is integrally formed on the outside of the adapter body, and the limiting platform is located at the end of the external thread.

[0009] Preferably, the inner diameter of the widest part of the medicine guiding groove is 3 mm, and the inner diameter of the narrowest part of the medicine guiding groove is 1.5 mm.

[0010] Preferably, a screwing platform is integrally formed on the outside of the bottom end of the adapter body, and the adapter body is in a cylindrical shape.

[0012] Preferably, the size of the connecting head matches that of the medicine guiding groove, and the size of the adapter body matches that of the connecting sleeve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the medicine guiding groove penetrating through the middle of the adapter body, with the inner diameter decreasing sequentially from the bottom to the head, the present utility model can connect syringe ports with different outer diameters. Through the external thread on the outer side of the head of the adapter body, on the one hand, it can be used to connect a cartridge injection needle, and on the other hand, it can be connected to the internal thread on the inner wall of the connecting sleeve, and a common injection needle can be connected through the connecting head.

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0020] An oral common syringe needle adapter, see Figures 1 to 3 , includes an adapter body 1, and also includes a first adapter mechanism and a second adapter mechanism; the first adapter mechanism: for connecting a cartridge injection needle, the first adapter mechanism includes a medicine guiding groove 11 and an external thread 13, the medicine guiding groove 11 penetrates through the middle of the adapter body 1, the adapter body 1 is in a cylindrical shape, the inner diameter of the medicine guiding groove 11 decreases sequentially from the bottom to the head, the inner diameter of the widest part of the medicine guiding groove 11 is 3 mm, the inner diameter of the narrowest part of the medicine guiding groove 11 is 1.5 mm, a screwing platform 12 is integrally formed on the outer side of the bottom end of the adapter body 1, and the external thread 13 is provided on the outer side of the head of the adapter body 1.

[0021] The drug guiding groove 11 is opened through the middle of the adapter body 1, and its inner diameter decreases from the bottom to the head, so that it can be connected to syringe ports with different outer diameters. The external thread 13 on the outer side of the head of the adapter body 1 can be used to adapt a card-type injection needle. The narrowest inner diameter of the drug guiding groove 11 is 1.5mm, which can ensure the smooth flow of the drug solution.
