Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bed equipped with an electrode applicator for high frequency thermotherapy.

High-frequency thermotherapy is a treatment in which a pair of electrode plates are brought into close contact with a living body and an induced current is applied to heat the affected area, such as cancer or a tumor.

This is because the heat resistance temperature of normal cells in living organisms is generally 43 to 4.
4°C, whereas cancer cells die at temperatures below 42°C, although this varies depending on the type. Therefore, if a living body is maintained at a temperature above 42'C and below 43'C, cancer cells will not cause any harm to normal cells. This is because only cells can be killed.

Further, subsequent research has shown that mild heating of the affected area to around 39-40°C is more effective than thermal therapy alone when used in combination with radiation therapy or chemotherapy.

In the case of this mild heating of about 39 to 40 degrees Celsius, the treatment takes a long time and must be repeated many times.Currently, it is difficult to efficiently treat patients with weakened physical strength while lying in bed. It is.

Moreover, it is often difficult to attach a pair of electrode applicators to, for example, the abdominal side and the back side, because even if one applicator is successfully attached, the other applicator may be misaligned or come off.

Additionally, if the electrode applicator contacts sweat, the sweat may heat up and cause burns.

Therefore, the present invention aims to provide a bed for thermal treatment in which one electrode applicator is attached to the bed surface, allowing efficient treatment while the patient is lying on the bed, and which also eliminates the risk of burns. An electrode applicator having a cooling bag body that is flexible enough to fit closely against the body and configured to circulate a cooling liquid inside the electrode applicator.
It is characterized by the structure provided on the bed body.

The present invention will be explained in detail based on the embodiments shown below. Reference numeral 1 denotes a bed body according to the present invention;
Cooling bags 21, 22, 23 with a diameter of about 20 cm are placed on the surface of the
, 24 and fixed electrode plates 31, 32, 33, 34 are provided.

The cooling bags 21, 22, 23, and 24 are made of rubber sacks like water pillows, and are filled with cooling liquid so that they can be circulated inside, so as to be in close contact with the body of the patient 8 lying on the bed body 1. The surrounding area is made of soft material.

Fixed electrode plates 31, 32, 33, and 34 are provided on the lower sides of the cooling bags 21, 22, 23, and 24, respectively, and are connected to one electrode of the high-frequency oscillator 7 via the selector 6.

Further, the cooling bags 21, 22, 23° 24 are connected to the cooler 12 and the pump 10 by a pipe 13 and a connector 20 for circulating coolant, and the coolant at about 4° C. is circulated in each cooling bag. It is configured as follows.

In this embodiment, the selector 6, the high frequency oscillator 7
, a pump 10, a cooler 12, and a pipe 13 are incorporated into the bed body 1.

On the other hand, reference numeral 5 denotes a movable electrode plate which forms a pair with the fixed electrode plate and is connected to the other electrode of the high frequency oscillator 7 through a conductive wire 51.

Reference numeral 4 denotes a cooling bag body provided on the movable electrode plate 5. Like the cooling bag body, the surrounding area is made of a soft material so as to be in close contact with the body of the patient 8. It has a connector 40 for connecting to a pump 11 and a cooler 12 provided inside the bed body 1 via a flexible pipe 14.

Note that, since the high-frequency oscillator 7 generates a large amount of heat, it is preferable to configure the high-frequency oscillator 7 so that the refrigerant in the cooler 12 is circulated for cooling.

In addition, a temperature sensor consisting of a thermocouple or the like is provided on the skin contact surface of each cooling bag body 4, 21, 22, 23.24 so that the skin surface temperature can be measured with a thermometer installed inside the bed body 1. It is preferable to configure

The manner in which the bed of the present invention is used will be explained based on the embodiment configured as described above. When the patient 8 is placed on the bed, the surfaces of the cooling bags 21, 22, 23, and 24 are brought into close contact with each other due to the load.

A moving electrode applicator is set above the affected area, and a fixed electrode plate located directly below the affected area is selected using the selector 6.

When the pumps 10, 11 and the cooler 12 are operated, the cooled liquid flows into the cooling bags 4, 21, and 4 of each electrode applicator.
22, 23, 24.

As the coolant, physiological saline with good conductivity is usually used, but it is not limited to this.

By activating the high frequency oscillator 7 to a predetermined output, thermal treatment can be performed on the affected area.

At this time, since the cooling liquid is circulating in the cooling bag body, the skin surface is constantly cooled and there is no danger of burns caused by sweating.

Furthermore, as in the embodiment, if all the equipment necessary for high-frequency thermal therapy is equipped in the bed body 1, the treatment can be performed in a normal hospital room by simply transporting the bed body 1, without having to set up a special treatment room. Can be done.

Furthermore, since the patient only needs to lie down on the bed, the patient can receive the treatment comfortably without feeling any fatigue even during long-term treatment.

As described above, the high-frequency thermal treatment bed according to the present invention has flexibility that allows it to adhere closely to the body, and is electrically independent and has a cooling bag configured to allow cooling fluid to circulate therein. A plurality of electrode applicators capable of supplying power to the body are successively installed along the recumbent position of the body on the bed main body, and the electrode applicator has a cooling bag body similar to the above, electrically paired with the electrode applicators. Since the electrode applicator is movable on the bed body, the patient simply lies on the bed and the electrode applicator comes into close contact with the patient's body, allowing treatment to be applied to the required areas sequentially by electrical switching without moving the patient's body. In addition, the pump and cooler for circulating the cooling fluid in the cooling bag body are installed in the bed itself, so there is no need to set up a special treatment room. However, it has the advantage of being able to perform thermal treatment easily and comfortably just by bringing in the bed itself, and is of great practical benefit.
