[0004]

The hose type spray device 12 has a hose 14 and a large-sized compressor 1.
Since it is connected to 1, the compressed air does not run short in the middle of the treatment for a long time. However, since the hose 14 needs to be drawn around, there are problems that the hose 14 is an obstacle and the workability is not good, and that the sterilization of the hose type spray device 12 including the hose 14 is troublesome. The hoseless type spray device 13
Since there is no hose 14, workability is good because it does not have a hose 14, but there is a problem that compressed air is insufficient in the middle of treatment during a long period of time, and a filling work is required each time.

Further, since both the hose type spray device 12 and the hoseless type spray device 13 send compressed air, even if the chemical solution or the washing water can be sprayed from the nozzle 16, a liquid such as pus in the affected area can be obtained. Since the object cannot be sucked and the range of adjusting the pressure of the compressed air is limited, the hose type spray device 12 can be used depending on the work content.
Alternatively, the hoseless type spray device 13 must be replaced, the range of use is limited, the compressor 11 for generating compressed air is large, and the size of the entire device is large. By the way, there was a problem that it could not be used.

It is an object of the present invention to obtain a miniaturized apparatus which can be used for both injection and suction, can be continuously used for a long time, has excellent workability, and can be used as a whole apparatus.
