Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a carbon lamp treatment device that treats an affected area of a human body by irradiating the affected area with arc light generated between carbon electrode rods. The present invention relates to a carbon lamp therapy device equipped with an arc point adjustment device that allows arc to be generated at an appropriate position at all times.

(Prior art and its problems) In general, a carbon lamp treatment device applies a commercial alternating current voltage between electrodes made of carbon rods (hereinafter referred to as carbon electrode rods), and generates an arc by discharge between the tips of the electrodes. The aim is to treat affected areas of the human body by irradiating the arc light. Therefore, in this type of carbon lamp therapy device, a reflector is provided around the arc light source to effectively utilize the arc light, and the arc discharge position, that is, the arc point, is located on the center line of the reflector. The structure is such that the irradiation to the affected area can be performed most efficiently when the irradiation point is in the position (appropriate position).

However, since the carbon electrode rods are gradually worn out by arc discharge, it is necessary to maintain a constant distance between the tips of the carbon electrode rods in order to keep the illuminance of the arc light constant. For this reason, conventionally, when the specified illuminance cannot be obtained due to wear of the carbon electrode rod,
Various carbon lamp therapy devices have been devised in which the distance between the tips of the carbon electrode rods is shortened so that a constant illuminance can be obtained. For example, it is disclosed in Japanese Utility Model Application No. 51-45289. This phototherapy device uses a pair of supporting members to movably support the carbon electrode rods so that their tips face each other, as a means of keeping the distance between the tips of the carbon electrode rods constant, and also feeds each carbon electrode rod. Pressure contact is made with a roller, and by rotating each feed roller using a combination of a single motor and gears, etc., or manual operation, each carbon electrode rod is moved left and right by the same distance, and the distance between the tips of the carbon electrode rods is kept constant. It is configured so that it can be held in In addition, the ``Skin disease treatment device using white bacteria'' disclosed in Japanese Patent Application Laid-Open No. 51-145187 also uses a similar arc discharge, and in order to adjust the reduction in illuminance due to consumption of the carbon electrode rod, manual adjustment is required. The structure is such that the distance between the tips of the carbon electrode rods can be maintained constant by operation.

However, in this type of carbon lamp treatment device, if one of the carbon electrode rods wears out on one side due to abnormal wear and there is a difference in the amount of wear between the two carbon electrode rods,
If an attempt is made to maintain a constant distance between the tips of the carbon electrode rods, the arc point will shift from the center line of the reflector and the affected area will not be irradiated efficiently. Therefore, the user has to manually adjust the arc point every time the arc point shifts, which is extremely troublesome.
In addition, if the arc point position is not adjusted even though the carbon electrode rod is worn out on one side in this way, the carbon electrode rod that has been worn out on one side will be supported and power will be supplied to the carbon electrode rod. There was a problem in that an arc would occur between the power feeding part and another carbon electrode rod, and the power feeding part could be damaged.

Furthermore, it is configured so that both carbon electrode rods are fed the same distance by manual operation or a feed roller driven by a single motor as described above, and the distance between the tips of the carbon electrode rods is kept constant. However, the feeding roller slips on the carbon electrode rod and the carbon electrode rod cannot be fed a predetermined distance, resulting in a feeding failure phenomenon. Therefore, if an attempt was made to maintain a constant distance between the tips of the carbon electrode rods, the arc point would shift from the center line of the reflector, resulting in the problem that irradiation of the affected area could not be carried out efficiently. .

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to solve the problem when there is a difference in the amount of consumption of carbon electrode rods, or when there is a problem in feeding the carbon electrode rods as described above. An object of the present invention is to provide a carbon lamp therapy device equipped with an arc point adjustment device that automatically adjusts the arc point to a proper position at all times even when a phenomenon occurs, and to simplify the structure thereof.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the means taken by the present invention are as follows. The carbon lamp treatment device 1 treats the affected area by irradiating the affected area with arc light generated between the carbon lamps, and includes a moving means 20 for individually moving each carbon electrode rod 10a, 10b, and a position detecting means for detecting the position of the arc point. 30, and a control means 40 for controlling the moving means 20 so that the arc point is at an appropriate position while detecting the arc point with the position detecting means 30.

The position detection means 30 includes three light receiving sensors 30
It is composed of a, 30b, 30c, a slit 32 provided in a reflecting mirror 31, and the like. Reflector 31
This is to effectively radiate the arc light generated between the carbon electrode rods 10a and 10b to the outside. On the center line of this reflecting mirror 31, that is, both feed rollers 21
A slit 32 is provided on the extension line from the midpoint of carbon electrode rods 10a and 21b.

b and 30c are on the back side of the reflecting mirror 31 and are arranged in a fan shape on the extension line of the carbon electrode rods 10a and 10b and the slit 32.

and a setting circuit 4 that can set the reference voltage in advance.
4, a first comparison circuit 45 that compares the reference voltage set by this setting circuit and the voltage detected by the voltage detection circuit 43, and three light receiving sensors 30.
A deviation detection circuit 48 detects the illuminance deviation of the arc light detected by the arc lights a, 30b, and 30c, a second comparison circuit 46 compares the illuminance deviation, and the above-mentioned It is comprised of amplifiers 47a and 47b that drive both left and right motors 20a and 20b to correct illuminance deviations.

Next, a method of using the carbon lamp treatment device 1 equipped with the arc point adjustment device 100 according to the present embodiment configured as described above will be explained step by step.

First, when the user operates the start switch 41, the starting circuit 42 is activated and both carbon electrode rods 10 are activated.
An arc occurs between a and 10b. At this time, the voltage applied between both carbon electrode rods 10a and 10b (hereinafter referred to as
The voltage detection circuit 43 measures the measured voltage (hereinafter referred to as "measured voltage"), and the first comparison circuit 45 determines whether the measured voltage matches the voltage set in the setting circuit 44 (hereinafter referred to as "set voltage"). . This set voltage corresponds to the distance between the two carbon electrode rods 10a, 10b when the illuminance of the arc light is optimal, and is incorporated in the setting circuit 44 in advance. If the measured voltage and the set voltage match, it means that the most suitable arc discharge is being performed, and no action is taken thereafter.

On the other hand, if the measured voltage and the set voltage do not match, the left motor 20a or the right motor 20b is driven via the second comparison circuit 46 and the left amplifier 47a or right amplifier 47b, and both carbon The distance between the electrode rods 10a and 10b is increased or decreased. By this operation, both carbon electrode rods 10a,
When the tips of carbon electrode rods 10b approach each other, the measured voltage drops, and when the tips of both carbon electrode rods 10a, 10b move apart, the measured voltage increases. Therefore, the above-mentioned approach operation or separation operation is stopped when the measured voltage and the set voltage match, that is, when the optimum arc light illuminance is obtained. If arc discharge continues in this state, both the carbon electrode rods 10a and 10b will gradually wear out, and the measured voltage will also gradually increase accordingly. The motors 20a and 20b rotate and both carbon electrode rods 1
The approach operation of 0a and 10b is performed to try to maintain the measured voltage at the set voltage.

In this way, the measurement voltage is always kept at the set voltage, in other words, the distance between both carbon electrode rods 10a, 10b is always kept constant, and the optimum arc illuminance can be obtained.

However, the rate at which both the carbon electrode rods 10a and 10b are worn out is not uniform and may decrease unevenly, and the sliding of the feed rollers 21a and 21b may cause the carbon electrode rods 10a and 10b to be fed the same distance on the left and right. There may be cases where there is no arc light, and if the above approach operation is repeated, the position where the arc light is generated will gradually shift from the initial position (on the center line of the reflecting mirror 31). To correct this, the moving means 20, position detecting means 30, and control means 40 according to the present invention operate as follows.

Now, if the arc point is shifted to the right from its initial position as shown by the broken line in FIG. do.
The arc light received by the three light receiving sensors 30a, 30b, 30c is detected by a deviation detection circuit 48 for the deviation of each illuminance, and is also detected by a second comparison circuit 46.
Each deviation is compared.

Now, since the arc point has shifted to the right, the illuminance of the left light receiving sensor 30a is lower than that of the other two light receiving sensors 3.
The illumination intensity is greater than that of 0b and 30c. In this case, a command to rotate left motor 20a to the left is given from the second comparison circuit 46 via left amplifier 47a, and a command to rotate clockwise is given to right motor 20b via right amplifier 47b. As a result, the left carbon electrode rod 10a is transferred to the left by the left feed roller 21a, and the right carbon electrode rod 10b is also transferred to the left by the right feed roller 21b. In this way, when the tips of both carbon electrode rods 10a and 10b are moved to the left while maintaining a constant interval, the above-mentioned 3.
The illuminance of the incident light to the three light receiving sensors 30a, 30b, and 30c changes respectively. In other words, a change occurs in the illuminance deviation. This change is constantly monitored, and when the deviation disappears, that is, the arc point is at the reflector 3.
1, the driving signals from the comparison circuits 45, 46 to both the left and right motors 47a, 47b are cut off, the transfer operation of both carbon electrode rods 10a, 10b is stopped, and the carbon electrode rods 10a, 10b are moved on the center line of the reflector 31. Sustain arc discharge.

Similarly, even if the arc point shifts to the left, the three light receiving sensors 30a, 30b,
30c, the left and right motors 47a, 47b are driven in accordance with the command from the second comparison circuit 46 to move both carbon electrode rods 10a, 10b to the right and move the arc point onto the center line.

As described in detail above, the present invention provides a motor 2 as a moving means 20 for both carbon electrode rods 10a and 10b.
Carbon electrode rods 10a and 20b are separately provided on the left and right sides, and three light receiving sensors 30a, 30b, 30c detect the deviation of the arc point and control the left and right motors 20a, 20b so that the deviation is eliminated. , 10b or slippage of the feed rollers 21a, 21b is adjusted to an appropriate position.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, the distance between the carbon electrode rods 10a and 10b to obtain appropriate illuminance is measured by the voltage detection circuit 43, but the voltage measurement may be replaced with a current measurement means. But it's okay. In addition, three light receiving sensors 30 detect the arc light entering through the slit 32 at the position of the arc point.
Although the judgment is made based on the illuminance deviation by a, 30b, and 30c, the number of light receiving sensors may be at least two or more. Furthermore, the light receiving sensor 30a,
If an image sensor is provided via a filter in place of 30b, 30c and slit 32, it becomes possible to simultaneously detect the distance between both carbon electrode rods 10a, 10b and the position of the arc point.

(Effects of the Invention) As described above, the carbon lamp therapy device equipped with the arc point adjustment device according to the present invention has a pair of carbon electrode rods arranged so as to be able to move toward and away from each other, and the control means to control the position detection means to arc the Both carbon electrode rods are moved by separate moving means while detecting the arc point, so that the arc point is always at the appropriate position.If there is a difference in the amount of wear of the carbon electrode rods, or Even if the carbon electrode rod fails to feed due to slippage, the arc point is automatically adjusted to the appropriate position at all times.
The affected area can be efficiently irradiated with arc light, and the risk of damage to the delivery section, which is conventional, can be avoided.
