Further, the base body includes a base and a top base combined.

Further, an inner chamber cannula inner tube is connected to the drug delivery tube.

Through the above technical features, the following effects can be achieved:

1. The present invention does not compress the medicine bottle, but uses the external gas supply member to input gas into the unfilled space of the medicine bottle, so that the medicine powder in the medicine bottle can be output under pressure, and there will be no medicine powder stuck in the medicine bottle. bottle, and the problem that affects the compression of the medicine bottle.

2. The air supply part of the present invention is provided with a dust filter, which can prevent the powder from entering the air pump when the air pump is repeatedly inflated.

3. When the medicine bottle is combined with the joint end of the base body, the medicine bottle can be stably fixed on the joint end by inserting the U-shaped latch on the opposite side of the neck of the medicine bottle.

4. The extension length of the sleeve of the seat body is longer than the gas feed end and the medicine feed end. When not in use, it can avoid collision and damage of the gas feed end and the medicine feed end, or prevent personnel from accidentally touching the gas feed end. The end and the drug-injecting end were punctured.
