The medical treatment instrument B, which is provided corresponding to each of the above, is provided with the switches (16) a, (16) b, (16) c for permitting the flow of the working medium necessary for its operation when the treatment instrument B is input. Yes,
The pressurized air supply circuit (9) has an air source (17), the water supply circuit (10) has a water supply source (18), an operating power supply circuit (11) and an illumination power supply circuit (12). A power source (19) is connected to the suction circuit (13), and a suction source (20) including a vacuum pump is connected to the suction circuit (13). Reference numeral (21) is an operation switch for outputting the working medium from the working medium supply circuit in which the supply of the working medium is set by controlling the operation of the working medium supply control section (14) by a hood operation, for example.

Then, in use, for example, in FIG. 1 in which the hand-held members (3) that are respectively adapted to the joint members (2) are connected and the compatible signals are output from the respective treatment instruments B to the identification command circuit (8), for example. First, the first treatment device Ba is attached to the holding member (5) a.
When it is detached and held by hand, a detection signal is output from the detection circuit (6) a and is input to the identification command circuit (8) via the latch circuit (7). Then, the identification command circuit (8) causes the identification signal corresponding to the therapeutic instrument Ba to be transmitted to the working medium supply control section (14) by matching the detection signal with the compatible signal from the therapeutic instrument Ba. Output. Then, the working medium supply control section (14) causes the working medium supply circuit (for example, in the case of the air turbine handpiece, the air turbine and the pressurized air for spraying) necessary for the operation of the first treatment instrument Ba according to the identification signal. Supply circuit (19), water supply circuit (10) for spraying out, and power supply circuit (12) for lighting

On the other hand, the detection signal from the detection circuit (6) a accompanying the removal of the first treatment instrument Ba is input to the priority holding circuit (15), and the priority holding circuit (15) opens and closes the switch corresponding to the treatment instrument Ba. (16) A switch that outputs a priority signal only to a (16)
A is opened.

When the operating switch (21) is operated from this state by, for example, a hood operation, only the various operating medium supply circuits that are in an operable state by operating signals are given to the operating medium supply control section (14), and the operation is performed. Medium is switch (16) a
And the first treatment instrument Ba is supplied via the flexible hose (1) a, and the treatment instrument Ba operates. In this state, even if the second and third therapeutic instruments Bb and Bc are handheld, the output state of the latch circuit (7) does not change, so that the output state of the identification command circuit (8) is maintained, and therefore the working medium The output state of the working medium from the supply control unit (14) is set to the switch (2

Then, all the switches (16) are closed and the identification command circuit (8) and the latch circuit (7) are reset.

When the hand-held member (3) is removed from the joint member (2) from the state shown in FIG. 1 and another non-supported hand-held member is connected, a compatible signal is not output from the compatible signal output unit (4), so that the treatment is performed. The identification command circuit (8) to which the detection signal from the detection circuit (6) is input by detaching the device does not output the identification signal. Therefore, even if the operation switch (21) is operated in this state, the operation medium supply circuit does not operate, and the treatment instrument connected to the unsupported hand-held member does not operate.

FIG. 2 shows another embodiment of the device of the present application, which differs from the above-mentioned embodiment in that the latch signal is omitted by operating the identification command circuit (8) by the priority signal from the priority holding circuit (15). According to this configuration, a detection signal is input from the detection circuit (6) to the priority holding circuit (15) by removing the therapeutic instrument B [Ba to Bc] from the holding member, and the priority holding circuit (15) ) Is inputted to the identification command circuit (8) only, the identification command circuit (8)
Is a treatment instrument B [Ba to Ba corresponding to the working medium supply unit (14).
The output state of only the working medium supply circuit necessary for the operation of [Bc] is set.

As described above, according to the present invention, the working medium supply circuit necessary for the operation of various treatment instruments in which the hand-held member is replaceable with the joint member is provided in the treatment apparatus body such as the dental unit, and the treatment is performed. When various therapeutic instruments are connected to the main body of the device through flexible hoses, and when an arbitrary therapeutic instrument is held by hand, the operation required to activate the therapeutic instrument based on the unique signal provided in the holding member of the therapeutic instrument By selecting only the medium supply circuit and setting it under suitable conditions, by operating the operation switch in this state, only the earliest treatment instrument held by hand was operated, and a hand-held member that was not compatible with the joint member was connected. In this case, since the treatment instrument is configured not to operate, even if a large number of treatment instruments are provided, the configuration in the treatment apparatus can be simplified by sharing the working medium supply circuit. In addition, it is convenient that only the earliest hand-held treatment device can be used with priority, and even if the user accidentally connects an inconvenient hand-held member with a different rating to the joint member, the operation will It has the advantage that the parts do not operate and can be used safely.
