Description

[Detailed description of the invention] (Industrial application field) This invention is mainly applied to dental treatment, and the treatment table or other treatment table is set at a predetermined treatment position and posture, and at least the gargling position and the treatment end position. 1
The medical shadowless system is equipped with an automatic position control device that automatically controls the position between two non-medical treatment positions and postures, and a surgical light for illuminating the treatment area is placed above the treatment table. This invention relates to a light blinking control device.

(Prior Art) Conventionally known medical operating light blinking control devices of this type include the following three types based on blinking operation mode.

(1) As shown in Fig. 5, the operating light body 2 is turned on and
An off switch 2A is attached, and this switch 2A
The power supply from the surgical light power supply 1 is cut off by the on/off operation.

(2) As shown in Fig. 6, a dedicated position detection limit switch 3 is attached to the treatment table that is turned on when the treatment table is moved to a predetermined treatment position, and a surgical light is connected to the limit switch 3. The on/off switch 2A attached to the main body 2 is electrically linked.

(3) As shown in Figure 7, when the position of a medical table equipped with an automatic position control device is controlled using the position detection signal of the medical table, and the position of the medical table matches the set position. The operating light is turned on by the setting completion signal, and is turned off by the signal when the position shifts from the set position. The above (3) shown in this Figure 7
The conventional operating light blinking control device will be explained in more detail.

In Fig. 7, 4 is a set operation switch;
It has a first operation control circuit 6 that drives an automatic position control circuit 8 so that the operation of the switch 4 causes the medical treatment table to be position-controlled to a predetermined medical treatment position/posture. Reference numeral 5 denotes a reset operation switch, which has a second operation control circuit 7 that drives the automatic position control circuit 8 so that the operation of the reset operation switch 5 causes the examination table to be positionally controlled to a non-treatment position. Reference numeral 9 denotes a surgical light blinking control circuit, which is connected to the first operation control circuit 6.
The operating light 10 is turned on by inputting an operation stop signal from the operating control circuit 7, and is turned off by a reset signal from the second operation control circuit 7.

The conventional example shown in (3) above is disclosed in Japanese Patent Application Laid-open No. 171040/1986.
The correlation operation between the position movement of the surgical light and the blinking of the surgical light disclosed in the publication is replaced with the correlated operation between the position control operation of the treatment table and the blinking control operation of the surgical light. It is something.

(Problem to be solved by the invention) Among the conventional examples explained above, in (1), medical operators have to operate the operating light to blink every time they perform a medical treatment, which is extremely troublesome. Not only is it
Generally, the operating lights are installed at a high position, which causes a lot of fatigue in operating them. However, if you leave the operating light on and use it, it is disadvantageous in terms of power consumption, and it is also difficult to use the treatment table, for example, in the position for gargling during dental treatment or the position at the end of the treatment. When a patient is placed in a non-medical position with the upper body erect, the patient's face approaches the illuminated surgical light, causing inconveniences such as irritating the eyes.

In addition, in the conventional example (2), when the treatment table is moved to a predetermined treatment position, the surgical light can be turned on automatically and the blinking operation can be simplified. In the position and orientation, for example, even if there is a case where the patient wants to turn off the surgical light, such as when a medical treatment is temporarily interrupted, the surgical light cannot be turned off. If an attempt was made to turn off the light in this state, it would require troublesome work such as switching the automatic lighting circuit to a manual lighting circuit.

Furthermore, in the conventional example (3), the position control operation of the treatment table and the flashing operation of the surgical light are synchronized, which is very advantageous in terms of operation. If you want to turn off the light when the patient is in a non-diagnosis position or turn on the light when the patient is in a non-diagnosis position, it is necessary to move the treatment table itself, making it difficult to turn on and off the surgical light arbitrarily. Furthermore, in the conventional example (3), the operating light is controlled to blink by comparing the position detection signal of the automatic position control device and the set position signal.
Incorporating a surgical light blinking control circuit into the circuit of the automatic position control device requires changing the circuit configuration of the automatic position control device, which poses a problem of increasing costs.

This idea was created in view of the above circumstances, and by rationally linking the operation of controlling the position of the treatment table and the operation of controlling the blinking of the surgical light, it is possible to reduce the number of operations performed by the operator and reduce operational fatigue. It is an object of the present invention to provide a medical surgical light blinking control device that can easily and quickly perform arbitrary blinking of a surgical light.

(Means for Solving the Problems) In order to achieve the above object, the medical surgical light blinking control device according to this invention automatically changes the treatment table into a predetermined treatment position and at least one non-treatment position. an automatic position control device that controls the position of the patient; a first operating switch that inputs a command signal to the automatic position control device to control the position of the medical table to a predetermined medical treatment position; a second operating switch for inputting a command signal to the position control device for controlling the position of the medical table to a non-medical position; a surgical light disposed above the medical table; When receiving an operation signal from the first operation switch, the operation lamp is turned on with a delay until the treatment table is controlled to a predetermined treatment position and stopped, and the second operation switch is operated. and a surgical light blinking control circuit that immediately turns off the surgical light when the signal is received, and the surgical light blinking control circuit controls the position of the medical table to a predetermined medical treatment position and stops. and a circuit that enables the operating light to be turned off by operating signals having different operation times to the first operating switch when the operating light is on, and a circuit in which the operating table is in a non-medical position. and a circuit that enables the operating light to be turned on by operating signals having different operating times to the second operating switch when the operating light is in a state where the operating light is off. .

(Function) According to the medical shadowless lamp on/off control device of this invention, by operating the first operation switch, the automatic position control device operates to control the position of the examination table to a specified examination position and posture, and then the position control operation stops, and the shadowless lamp is automatically turned on with a delay by the operation of the shadowless lamp on/off control circuit. In this state, by operating the first operation switch for a different length of time than the above, it is possible to turn off the shadowless lamp at will while keeping the examination table in the specified examination position and posture.

In addition, by operating the second operation switch, the automatic position control device operates to control the position of the treatment table to the non-medical position, and at the same time, the operation of the operating light blinking control circuit causes the treatment table to be placed in the non-medical position. The shadow lights are immediately extinguished. In this state, by operating the second operation switch for a different length of time than the above, it is possible to arbitrarily turn on the surgical light while keeping the treatment table in the non-medical treatment position.

In the same figure, 22A is a position control signal input circuit to the autoset A, and this input circuit 22A includes the following: A short-time operation signal detection circuit 22A-1 and a long-time operation signal detection circuit 22A-2 are connected to the first operation switch 12 for discriminating two types of operation signals a1 and a, long and short, which have different operation times. has been done. 22B is a position control signal input circuit to autoset B or autoreset C, and like the input circuit 22A, this input circuit 22B also has an input circuit for controlling the second operation switch 13 or the third operation switch 14.

Reference numeral 22E denotes a lighting signal output circuit, which is driven by the output signal of the long-time operation signal detection circuit 22B-2 to turn on the surgical lamp 23 via the surgical lamp control circuit 22F.

Next, the operation of the above configuration will be explained with reference to the timing chart of FIG.

First, when the treatment table 30 is in the auto-reset C shown in FIG. When inputted into the operation switch signal detection circuit 15, the automatic position control circuit 16 is activated, and the treatment table 30 is moved to the third position via the drive control circuits 17, 19 and the position detectors 18, 20.
The position is controlled to autoset A as shown in Figure a. At this time, the operation switch signal detection circuit 1
The operation signal a branched at step 5 is input to the input circuit 22A in the surgical lamp blinking control circuit 22, passes through the short-time operation signal detection circuit 22A-1, drives the delayed lighting signal output circuit 22C, and thereby , operating light 23
is turned on after being delayed for a predetermined time T. Such delayed lighting of the surgical light 23 is effective in preventing the patient on the treatment table 30 from being dazzled by the surgical light 23 and from having his or her eyes irritated.

Next, when the treatment table 30 is in the autoset A shown in FIG.
When turned on for a long time t2 of about seconds,
The operation signal a1 is sent from the input circuit 22A in the operating light blinking control circuit 22 to the long-time operation signal detection circuit 22.

When the ON operation is performed and the operation signal b or c is input to the operation switch signal detection circuit 15, the automatic position control circuit 16 is activated and the treatment table 30 is moved through the drive control circuits 17, 19 and the position detectors 18, 20. The position is controlled to autoset B as shown in FIG. 3b or autoreset C as shown in FIG. 3c. At this time, the operation signal b or c branched by the operation switch signal detection circuit 15 is transmitted to the operating light blinking control circuit 2.

2D is driven, and the surgical light 23 is immediately turned off.

Next, when the treatment table 30 is in the auto-set B shown in FIG. 3b or the auto-reset C shown in FIG. When the third operation switch 14 is turned on again for a long time t4 of about 1 to 2 seconds, the operation signal b1 or c
1 is the input circuit 22B in the operating light blinking control circuit 22
, enters the lights-off signal output circuit 22E via the long-time operation signal detection circuit 22B-2, and then enters the operating light control circuit 2.

As described above, the operating light 23 is automatically turned on with a delay in the position control operation for autoset A, and in this state, the operating light 23 can be arbitrarily turned off by operating the same operation switch 12 again. In addition, by automatically turning off the surgical light 23 immediately with the position control operation to autoset B or autoreset C, and operating the operation switch 13 or 14 again in this state, The surgical light 23 can be turned on arbitrarily. Furthermore, when the operating light 23 is off in autoset A, by turning on the first operation switch 12 for a short time or turning on the second and third operation switches 13 and 14 for a long time. ,

(Effect of the invention) As already clarified from the above explanation,
According to this invention, the position control operation of the treatment table and the blinking control operation of the operating light are rationally related to each other, thereby reducing the number of operations required for these control operations and reducing operational fatigue. This allows the prescribed treatment to be carried out quickly and efficiently.

Moreover, you can freely turn off the operating light when you are in a predetermined treatment position and turn on the operating light when you are in a non-treatment position. It is possible to blink the light very easily and quickly by operating the operation switch that is originally provided to command the position control operation, without requiring the trouble of moving the light or switching the lighting circuit. It is possible to demonstrate excellent operability.

In addition, there is no need to change the circuit configuration of the automatic position control device, and the overall structure can be easily constructed at low cost by adding a simple circuit.

In addition, since the operating light can be blinked in conjunction with the position control operation of the treatment table, the operator does not have to touch the operating light directly, making it extremely hygienic. When operating the switch, dust may get on the operator's hands or fall on the patient, but this idea eliminates such concerns.
