2. Description of the Related Art In a dental treatment room, many outpatients come and go, and if care is not taken to sterilize and disinfect the room, many microorganisms may remain on the floor, surfaces of instruments and appliances, or in the air. The dental treatment room may become a place where the pathogenic microorganisms are transmitted from patient to patient, patient to operator, or operator to patient. In particular, nosocomial infections caused by Staphylococcus aureus have recently attracted attention.

FIG. 1 is a diagram for explaining an embodiment of the present invention. First, a conventional dental unit will be described with reference to FIG. In FIG. 1, 10 is a dental unit, 11 is a treatment chair, 12 is a surgical light, 13 is a spittoon, 14 is a work table, 15 is a saliva discharge pipe, 16 is a vacuum hose, and 20 is a water supply / drainage pipe box (joint box). As is well known, the saliva ejecting tube 15 is put into the oral cavity of a patient and sucks and discharges the waste (mainly waste fluid) generated during dental treatment. Thus, in dental treatment, a vacuum source (vacuum), an air pressure source (compressor), in order to suck and dispose of filth from a spitton, saliva ejector, etc., or to drive an air turbine, a spray, etc. A water pressure source etc. is required, and those pipes are required. These pipes are connected in a water supply / drainage pipe box (joint box) 20 provided in the treatment room. An air vacuum tank 21 is provided in the joint box 20, and saliva or the like in the oral cavity is sucked into the tank 21 through a vacuum hose 16 from the saliva ejector 15 and is sucked through the vacuum tube 16. Since the gas is separated from the gas, the gas is discharged into the joint box 20 through the filter 22, and the waste liquid is discharged through the drain pipe 23.

Thus, in a large dental unit having a vacuum device or a large dental treatment room having a vacuum device, the vacuum hose 16 is directly connected to the vacuum device to exhaust and exhaust the gas. Both liquids can be cleaned. The connection between the vacuum device and the saliva ejector is usually performed in the joint box 20, but it is not always necessary. In this way, the drainage liquid and the exhaust gas sucked through the saliva discharge pipe 15 and the vacuum hose 16 are guided to the joint box 60 through the vacuum pipe 29 and separated into the gas and the liquid by the gas-liquid separation tank 61. .. The separated gas is discharged through the filter and the waste liquid is discharged through the drain pipe, as in the case of the joint box 20.

As described above, in the conventional joint box, the contaminated air sucked from the oral cavity of the patient is discharged into the treatment room through the filter, and the filter removes dust and deodorizes (deodorizes). Although it is possible to add an antibacterial action to, it is not possible to have a sterilizing action. Therefore, bacteria are mixed in the air exhausted through the filter, and there is a risk of nosocomial infection by the bacteria. Moreover, since the waste liquid is also discharged as it is, it is unsanitary and pollutes the surrounding environment.
