Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a therapeutic apparatus for treating humans and small animals in warm water having a temperature higher than body temperature to treat AIDS and cancer.

[0002]

2. Description of the Related Art In general, treatment of AIDS and cancer in humans and animals includes a method of heating a virus with microwaves and a method of destroying cells with a laser.

This is a method which is commonly used because both AIDS virus and cancer cells are vulnerable to heat, but other methods include the use of an anti-cancer agent or a method of heating a chip agent placed in the vicinity of an affected part in the body to destroy malignant cells. is there.

As another treatment method, there is a hyperthermia treatment method known in the medical field.

A patent mainly on hyperthermia is disclosed in Japanese Patent Laid-Open No. Hei 10
-33626 gazette. This method is 4
The hot water of 1 to 42 degrees is put in the bathtub and the temperature of the deep part is raised by keeping the specimen (treatment object) stationary for several hours, so that the cancer cells are destroyed by heat.

Generally, it is said that the treatment temperature of AIDS virus (HIV) is 41.5 degrees Celsius and the treatment temperature of cancer is 42.5 degrees Celsius, but this temperature is the optimum temperature for treatment, During the treatment, even if the treatment is performed at an optimum treatment temperature, a vertical width of about 0.5 degrees is given depending on the age of the sample, the degree of progress of the medical condition, and the like.

As described above, the hyperthermia treatment involves putting the human body or the body of a small animal into the hot water in the aquarium with the neck and the upper part exposed above the surface of the bath, but the preparation work is difficult. is there.

In particular, in the preparatory stage before the treatment, as described above, since it is necessary to store the amount of hot water in the water tank in a short time, a large amount of hot water is added all at once by the water heater, but the temperature of the hot water stored in the water tank is If it is higher than the treatment temperature, it needs to be lowered to this treatment temperature.

As another factor for lowering the hot water temperature in the aquarium, it is necessary to ensure safety when physiological factors such as the heartbeat and respiratory rate of the human body or small animals greatly change during treatment. Sharply lower.

[0010]

As described above, the temperature of the hot water in the water tank is controlled based on the set temperature. For example, when the set temperature of the hot water is raised, it takes a short time. After pouring hot water to raise the hot water temperature to the set temperature, when the hot water temperature reaches the set temperature, the heating temperature is switched to heating by the heater and the set temperature is maintained while gradually heating and stopping. Constant temperature control is performed.

For this reason, even if the temperature is switched to the constant temperature control immediately after reaching the set temperature, the temperature continues to rise due to the residual heat of the high temperature water and rises above the set temperature. Therefore, the temperature is lowered to the set temperature by using the cooling means. Not only was it bothersome and time consuming.

Similarly, there is a method of directly dropping water into the warm water in the water tank to lower the set temperature, but the rate of reduction is too fast and the temperature falls below the set temperature. It needed to be warmed, which was a loss of time.

Particularly, when the set temperature is raised during the treatment, there is a risk that the human body and the small animals will have aftereffects if the temperature rises above the set temperature.

According to the present invention, when the set temperature of the hot water is changed, the temperature is brought close to the set temperature in the shortest possible time, but the set temperature is not exceeded, and the temperature is controlled to a stable constant temperature. is there.

Next, the operation from the preparation before the start of treatment to the treatment will be described with reference to the flowcharts of FIGS. 3 and 4 and the characteristic diagrams of FIGS. 5 and 6.

First, the pouring electromagnetic valve (13) is opened to slightly lower the hot water in the hot water tank (2) and the hot water is poured into the water tank, and the water level sensor (28) detects that the water has risen to a predetermined water level. (S1), (S2).

When the predetermined water level is reached, the pouring solenoid valve (13) is closed to stop tapping (S3), and the temperature is set according to the treatment content. Here, the treatment temperature is relatively low. The case of setting to 40 degrees (t1) will be described (S
4). Although the temperature is raised to the set temperature by heating the electric heater (20) (S5), since the set temperature requires delicate temperature management, when the temperature rises by 0.05 degrees, the electric heater (20) Stop heating (S6), (S
7).

After that, when the temperature of the hot water slightly drops and drops by 0.05 degrees (S8), the treatment by the constant temperature control means (31) is started (S9), (S10).

Here, when the set temperature (treatment temperature) is changed by the temperature setting means (30) (S11), that is, the treatment temperature is raised twice in order to enhance the treatment effect while observing the state of the sample. When done (S12), the pouring solenoid valve (1
3) is opened and the mixing valve (8) is switched to pour slightly higher temperature hot water into the water tank for direct heating (hot water temperature rise by high temperature water) (S13).

As shown in FIG. 5, the temperature rise curve of the hot water temperature rapidly rises from 40 degrees, and the output of the temperature measurement value (A) by the temperature detection means (34) is lower than 42 degrees (D
When it becomes the same as the absolute value of (1) (41.7 degrees) (S1

(S17), (S18).

At the time of step (S4), the treatment temperature set by the temperature setting means (30) is 42 degrees (t
In the case of 2), the indirect heating of the electric heater (20) is similarly performed, and when the temperature measurement value rises by 0.05 degrees from 42 degrees, the heating of the electric heater (20) is stopped, When the temperature also decreases by 0.05 degrees, the temperature shifts to constant temperature control for maintaining the treatment temperature of 42 degrees and the treatment is started (S19) to (S24).

8) Open the water supply solenoid valve (24) and close the pouring solenoid valve (13) to pass tap water through the cooler (23) to perform indirect cooling by gradually lowering the hot water temperature in the water tank (S2).
9).

Eventually, when the hot water temperature drops to an absolute value of 40.1 degrees according to the data (D3) of 0.1 degrees (S30), the water supply solenoid valve (24) is closed to perform natural cooling (S31),
When the hot water temperature drops to 40 degrees with the passage of time, constant temperature control for maintaining the hot water temperature is performed and the treatment is continued (S32).
~ (S34).

The reason for lowering the set temperature (treatment temperature) is to change it while observing the state of the sample when it is judged that the treatment temperature preset by the doctor during treatment is high and the sample (H) is overloaded. This is the case.

[0042]

As described above, according to the present invention, when the temperature setting means is set and set to a higher set value than the preset value, the hot water temperature does not reach a specified value lower than the preset value by a constant temperature. Since it is heated directly and heated by indirect heating after reaching the specified value, the temperature is raised rapidly until the temperature is changed and the time is shortened, and gradually when the hot water temperature approaches the set value. Since it is heated up to the set temperature, the hot water temperature does not exceed the set temperature and adversely affect the sample.

Further, when the temperature setting means is changed and set to a lower set value than the preset value, direct cooling is performed until the hot water temperature reaches a specified value that is a certain temperature higher than the preset value, and thereafter indirect cooling. After that, the constant temperature control to maintain the set temperature is performed, so that the hot water temperature is rapidly lowered to save the wasted time during the treatment time, and the indirect cooling prevents the temperature from dropping below the set temperature. It is possible to maintain the changed set temperature in a short time.
